Unemployment rates don't prove anything by themselves, even though these two nearly matching it trended downward until the late 2000s.

We get the line so labeled because the actual rate of unemployment has varied widely in the United States.

The natural rate of unemployment would decline until the late 2000s, when it began to rise again.

Let's look at two examples to see how departures from the natural rate of unemployment can occur.

Imagine if the government used fiscal or monetary policy to boost the economy.

For reasons that will soon become clear, suppose that this policy surprises decision makers throughout the economy because they did not anticipate that it would happen.

Workers and owners of capital and raw materials revise their expectations.

The long-run real GDP per year is fifteen trillion, but at a higher price level.

Expec Price Level tations of input owners are revised over time.

People looking for jobs find it takes longer than expected.

As real GDP returns to $15 trillion, the price level will decline to 116.

The expectations of input owners are revised at the lower price level.

An unexpected increase in aggregate demand causes the price level to rise and the unemployment rate to fall.

Although the relationship between unemployment and wages was presented only as an empirical regularity, economists quickly came to view it as repre prices.

ThePhillips curve suggested that it was possible for discretionary policymakers to fine-tune the economy by selecting the policies that would produce the exact mix of unemployment and inflation that suited current government objectives.

The natural unemployment rate applies to a long-run equilibrium in which short-run adjustments have ended.

The natural rate of unemployment varies by a relatively greater amount than the NAIRU.

If aggregate demand fluctuates up and down at random, this is a good way for workers to view the world.

When the expected inflation rate was zero, a 3 percent rise in nominal wages meant a 3 percent expected rise in real wages, and this was enough to induce some individuals to take jobs rather than remain unemployed.

When workers expect the inflation rate to go up, rising nominal wages will not be enough to get them out of unemployment.

The effects of shocks on the core infla prefer to remove food and energy prices from the inflation rate for a long time.

Policymakers seek to take advantage of unforeseen changes in fiscal or monetary policy when there is a departure from the natural rate of unemployment.

The assumption that economic participants think rationally about the future as well as the present is one of the key features of current macro policy research.

The rational expectations hypothesis holds that Abraham Lincoln was correct when he said, "You can fool all the people."

The economy's response to a change in monetary policy is an example of how rational expectations operate in the new classical perspective.

The location of the short-run aggregate supply curve will cause the price level and real GDP to rise to 120 and $15.3 trillion, respectively.

A $1 trillion increase in money supply causes the demand curve to shift.

Even as real GDP declines back down to $15 trillion, the price level continues its rise to 122.

The perspective given by the rational expectations hypothesis is that wages and prices are flexible in a purely competitive environment.

Workers and other input owners should be aware that the money supply is going to increase.

They will go to their employers and insist that their nominal wages move in line with the higher prices.

This is the only way to protect real wages from falling due to the increase in money supply.

Our discussion assumed that economic participants knew in advance exactly what the change in monetary policy would be and when.

The future course of monetary policy is not announced by the Federal Reserve.

The Fed tries to keep most of its plans secret, announcing only in general terms what policy actions are intended for the future.

Economic participants have great incentives to learn how to predict the future behavior of the monetary authorities, just as businesses try to forecast consumer behavior and college students do their best to forecast what their next economics exam will look like.

Even if the economic participants are not perfect at forecasting the course of policy, they are likely to come a lot closer than they would be.

It is likely that the Federal Reserve makes mistakes, meaning that the money supply may change in ways that the Fed does not predict.

There is no guarantee that other economic participants would fully forecast the actions of the Fed.

The result is a rise in real GDP in a short period of time.

The rise in real GDP will lead to an increase in employment and a fall in the unemployment rate.

The effect on real variables will disappear in the long run because people will think that the Fed increased the money supply in a way that fooled them.

When confronted with the policy irrelevance proposition, many economists began to reexamine the first principles of macroeconomics with fully flexible wages and prices.

Some economists argue that real forces can help explain economic fluctuations.

The new long-run aggregate supply curve is associated with the lowered output of oil.

Second, the higher costs of production occasioned by the rise in oil prices induce firms to cut back production, so real GDP falls to $14.7 trillion in the short run.

The reduction in oil supplies affects the owners of nonoil inputs.

Some workers who were willing to continue on the job at lower real wages in the short run will eventually decide to switch from full-time to part-time employment or to drop out of the labor force altogether.

Lower employment and a higher unemployment rate are associated with the decline in real GDP.

In the early 1970s, Congress enacted steep increases in marginal tax rates and implemented a host of new federal regulations on firms.

Stagflation episodes were prevented by increases in oil supplies, cuts in marginal tax rates, and deregulation during the 1980s and 1990s.

Even if prices and wages are flexible, shocks such as sudden changes in tech information, an understanding of government nology or the supply of factors of production can affect the economy.

Monetary policy actions can't change the rate of unemployment or real GDP.

The policy irrelevance proposition and the idea that real shocks are important causes of business cycles are major attacks on the desirability of trying to stabilizing economic activity with activist policies.

The rational expectations hypothesis is combined with the assumptions of pure competition and flexible wages and prices to create anti-activism suggestions.

Market clearing models of the economy are not believed to explain business cycles by economists who see a role for activist policymaking.

Keynes assumed sticky wages and prices in his major work, which they argue is important in today's economy.

The Federal Reserve Bank of New York estimates the costs weeks at a time for Pinelopi Goldberg and Rebecca beers.

Retailers change their prices slightly more often than the market for beer imported into the United States.

The argument favoring active policymaking as a means of preventing substantial short-run swings in real GDP and employment is strengthened by sticky prices.

In the short run, the aggregate supply curve is horizontal if a significant portion of prices don't adjust quickly.

The largest decline in equilibrium real GDP will be caused by 2 shown in panel a.

The theory presumes that small menu costs cause firms to keep their prices the same.

Real GDP would rise in the short run if aggregate demand increases.

Firms would gain sufficient profits from raising their prices to compensate for menu costs in the long run, and the short-run aggregate supply curve would shift upward.

Panel (a) shows that when prices are sticky, the short-run aggregate supply is horizontal, so that the price level falls to 116 and real GDP returns to $15 trillion at the point curve.

Producers think that they can increase their degree by cutting prices and paying menu costs, in the long run.

The period of contraction experienced by the economy may be brief if the policymaker acts quickly.

It is possible for active policymaking to moderate or even eliminate recessions.

Early in 2009, the federal government increased its spending by the largest real GDP.

Each $1 of government expenditures percentage in a single year since World War II was the worst he could find.

The Economic Advisers issued a report that provided a justification for the government's very active fiscal policymaking.

The government spending had failed to boost money, solvency, and growth according to his judgement.

By "exploitable," economists mean a relationship that is sufficiently predictable and long-lived to allow enough time for policymakers to reduce unemployment or to push up real GDP when economic activity falls below its long-run level.

The existence of a policy-exploitablePhillips curve relationship between inflation and unemployment has been debated by economists for more than 40 years.

The lack of a long-lived relationship between inflation and unemployment is not a concern for today's Keynesian theorists.

According to the new Keynesians, the most important thing for policymakers is whether the relationship is exploitable in the near term.

Policymakers can intervene in the economy if unemployment and real GDP vary from long-run levels.

Menu costs reduce firms' incentive to adjust their prices according to the new Keynesian theory.

Firms take the expected future inflation rate into account when setting prices at the present time, as it signals how much equilibrium prices are likely to increase during future months.

The average inflation-adjusted per-unit costs that firms incur in producing goods and services should affect current inflation, according to new Keynesian theory.

Keynesians propose a positive relationship between inflation and an aggregate measure of real per-unit costs faced by firms throughout the economy.

Media reports often refer to changes in inflation expectations and firms' production costs as signals of altered inflationary pressures.

The horizontal new Keynesian aggregate supply curve will remain in place if the average interval between firms' price adjustments is long.

Real GDP will be negatively affected by a decline in aggregate demand.

There will be more scope for activist policymaking to be able to boost aggregate demand and stabilization of real GDP.

There will be less scope for activist policies to stabilizing the economy because of the fact that faster adjustments of prices will tend to reduce movements in real GDP and the unemployment rate.

Calculating the average interval between price changes in national economies is difficult.

New Keynesian inflation dynamics yielded estimates of average price PART 4 # money, solvency, and growth adjustment intervals for the United States for two years.

There isn't much agreement about how much scope activist policymakers might have to fix the economy under the new Keynesian theory.

Many people who have never taken a principles of economics course think that the world's governments should work to achieve high and stable real GDP growth and a low and stable unemployment rate.

There are a number of factors involved in assessing whether policy activism is better than passive policymaking.

Table 17-1 summarizes the issues involved in evaluating the case for active policymaking.

You may be frustrated by the current state of thinking on the relative desirability of active or passive policy making.

Most agree that business cycles are affected by aggregate supply shocks.

A number of economists continue to argue that there is evidence that prices and wages stay the same.

Monetary and fiscal policy actions can offset shocks in the short run and possibly even in the long run, the effects that aggregate demand would otherwise have on real GDP and unemployment, they argue.

The diverging perspectives help explain why economists differ about the advisability of pursuing active or passive approaches to macroeconomic policymaking.

Different interpretations of evidence on the issues summarized in Table 17-1 on the facing page will likely continue to divide economists for years to come.

The short-run aggregate supply curve can be stable if activist policymaking is stickiness.

This is possible, according to the theory, the largest possible effects on real GDP in the short run, if policymakers can exploit the trade-off greatest ability to stabilizing real GDP.

During the years leading up to and including the American Economic Association annual meetings, the Fed's forecasts of inflation listen to Ben Bernanke discuss Fed policymaking prior to and during the financial meltdown.

The Fed adjusted the growth of the discretionary policies on the inflation rates it actually money supply in a way that moved market interest rates tolev observed instead of on inflation forecasts that were nearly always wrong.

If the Fed permits rapid growth in the money supply, revenue gains from changing prices can be more important than small menu costs.

The fact that people anticipate method for measuring inflation expectations is a signal that Treasury inflation-protected securities offer many economists.

There is a guaranteed fixed inflation-adjusted fuel inflation throughout the coming decade for people who hold TIPS.

According to return, the interest rate they require from these securities the theory of new Keynesian inflation dynamics, a conse is lower than the rate people require to hold non-inflation protected Treasury securities.

The equilibrium rate of unemployment price level and inflation are caused by the Study Plan 17.2 aggregate demand that causes a drop in the unem nonaccelerating inflation.

If people anticipate policymakers' efforts to exploit thePhillips curve trade-off via inflationary policies aimed at pushing down the unemployment rate, input prices such as nominal wages will adjust more rapidly to an increase in the price level.

The economy will adjust more quickly to the natural rate of unemployment as a result of the shift in thePhillips curve.

Wages and other input prices adjust immediately if people completely anticipate the actions of policymakers.

The case for active policymaking can be weakened by real business cycles caused by technological changes and labor market shocks.

Real GDP can be affected by changes in aggregate demand in the short run.

Discretionary policy actions can stabilization real GDP if prices and wages are too inflexible in the short run.

List possible factors affecting the military as part of the labor force.

The current group of Fed officials is following Chapter 11 and the new Keynesian theory indicates that the short-run to reduce the unemployment rate is possible.

The rational short-run increases in real GDP largely to expectations hypothesis is shown to be true by the real-business-cycle approach.

If you notice an inverse relationship between inflation and ployment, it's time to look at the data.

The existence of dead growth by helping to jump-start businesses capital retards investment and economic operating in the private sector, which is why a number of governments have sought to promote higher rates of economic growth.

Government inefficiencies have led to the creation of programs that help entrepreneurs open large quantities of dead businesses in the developing world.

You will be able to evaluate the prospects for global economic growth after reading this chapter.

Population growth doesn't mean an increase in labor resources in the poor regions of the world.

In China, the government has imposed an absolute limit on the number of children a woman can have.

A higher population reduces per capita real GDP if a country has fixed borders.

A higher rate of labor force participation by a nation's population contributes to increased growth of real GDP.

The relative freedom of a nation's residents is a crucial factor in economic growth.

The Heritage Foundation's evaluations of the world's nations over the past 30 years show that many are growing much more degree of economic freedom.

Negative rates of per capita income growth have been experienced in more than 30 countries.

17 percent of the world's people are granted high degrees of economic freedom by 17 nations.

The nations with the highest population densities account for 81 percent of world output.

The Indian government requires farmers to sell their beans to a middleman who resells them in wholesale markets.

Farmers are able to give the middleman an advantage in price negotiations because they have this information.

Economic freedom is more important than the right to openly support national leaders.

When nondemocratic countries achieve high standards of living through consistent economic growth, they become more democratic over time.

Dead capital is one of the most significant obstacles to growth of per capita incomes in the world's poor countries.

Capital goods include physical structures used to house both business operations and labor resources.

According to current estimates, there are more than $9 trillion worth of unofficial, nontransferable physical structures in developing nations around the world.

People in developing countries can't easily trade their capital goods because they don't officially own them.

In Cairo, Egypt, a city with an estimated 90 percent of all physical structures unofficially owned, a hypothetical situation could be faced by an individual.

If this person unofficially owns a run-down apartment building, they have no official title of ownership.

The indi can't sell or lease the structure to the new firm because he doesn't have enough capital to formally own it.

People who unofficially own capital goods can't use them efficiently.

Large quantities of capital goods are inefficiently employed in the developing world.

When we take production choices into account, any society faces a trade-off between consumption and capital goods.

When we choose to aim for more future economic growth to allow consumption of more goods in the future, we must allocate more resources to producing capital goods today.

Society must allocate less resources to the current production of consumption goods in order to incur an opportunity cost.

In a developing country, the inefficiencies of dead capital greatly reduce the rate of return on investment by individuals and firms.

Economic growth can be hampered by the resulting disincentives to invest in new capital goods.

The problem of dead capital in developing nations is often caused by inefficient government regulation.

Governments in many of the world's poor nations place a lot of obstacles in the way of entrepreneurs who want to own capital goods.

In addition to creating dead capital, overzealously administered government regu lations that impede private resource allocation tend to reduce investment in new capital goods.

There is less incentive to invest if capital goods can't be easily devoted to their most efficient uses.

The relationship between per capita incomes and government inefficiency is shown in Figure 18-1 on the next page.

The economies of countries with less efficient governments tend to grow at a slower rate.

bureaucratic inefficiencies complicate efforts to direct capital goods to their most efficient uses The index of Bureaucratic Inefficiency is a measure of economic growth in poor countries.

It is not possible for loan applicants to offer as capital assets that they do not own.

If government rules and inefficiencies prevent the marketability of capital assets, a lender is unlikely to accept them as security.

Tens of millions of people are getting access to credit for the first time in their lives in some of the least developed countries.

It is difficult for a buyer to trade a large portion of capital goods.

Private markets can be used to find ways to direct capital goods to their best uses.

Between 1995 and 2007, at least $150 billion per year in private funds flowed to developing nations in the form of loans or purchases of bonds or stock.

During the Panic of 2008, international investors stopped lending to developing countries or sold off their bonds.

This is a small part of the annual net investment in the United States.

Most of the funds that flow into developing countries are used to finance investment projects.

It is difficult to finance capital investment in developing nations with international flows of funds.

Many investment on developing nations go to stand ready to withdraw their financial support at a moment's notice due to the analysis of the effects of foreign direct informational problems to which they are exposed.

Banks and investors may be less willing to channel funds to creditworthy borrowers if they can't identify higher-risk individuals and firms.

In light of the adverse selection problem, anyone thinking about funding a business endeavor in any locale must carefully study the firm.

The potential for moral hazard requires a lender to a firm or someone who has purchased the firm's bonds or stock to continue to monitor the company's performance after providing financial support.

Financial intermediation is still relatively undiscovered in less advanced regions of the world.

Individuals interested in financing potentially profitable investments in developing nations can't rely on financial advisers in these countries.

Concerns about adverse selection and moral hazard can be a significant obstacle to economic growth in some countries.

The U.S. use other nations when they consider lending to firms in developing ment officials disburse foreign aid.

It is not apparent that the US government is any people's money, and other things being equal, hence do not have strong personal incentives to avoid direct funds to worthy projects in developing coun funding projects.

Private individuals government officials distributing foreign aid have fewer incentives than private parties to identify risks from asymmetric information problems.

Those who are willing to consider making loans or buying bonds in developing nations should either do their own research or follow the example of other investors who are better informed.

Many relatively unsophisticated lenders and investors, such as relatively small banks and individual savers, rely on larger lenders and investors to evaluate risks in developing nations.

Some economists think that a follow-the-leader mentality can influence international flows of funds.

Firms and governments withdraw their foreign investments stocks quickly.

The world economy shrank for the first time in decades as Asian nations weathered the crisis relatively well.

International flows of private funds to developing nations can be affected by adverse selection and moral hazard problems.

The World Bank and the International Monetary Fund are at the center of government efforts to attain higher rates of global economic growth.

Governments and firms in these countries usually seek loans from the World Bank to finance specific projects, such as better irrigation systems, road improvements, and better hospitals.

Approximately 10,000 people are employed by World Bank institutions to coordinate funding of investment activities undertaken by various governments and private firms in developing nations.

Firms in developing nations can't communicate effectively with extra 10 cellphones per 100 people.

Government-operated nation's average annual rate of economic growth is 0.8 percentage point.

The primary function of the International Monetary Fund was to provide short-term loans.

The demand for short-term credit declined after the 1970s, and the International Monetary Fund expanded its lending programs.

It now provides certain types of credit directly to poor and heavily indebted countries, either as long-term loans intended to support growth-promoting projects or as short- or long-term assistance aimed at helping countries experiencing problems in repaying existing debts.

The International Monetary Fund seeks to assist any member that is experiencing an unusual fluctuation in exports or imports, a loss of confidence in its own financial system, or spillover effects from financial problems in other countries.

The World Bank's client nations have meager economic growth in recent decades.

The average resident of a nation that receives World Bank assistance lives on less than $2 per day.

Mexico, Thailand, Indonesia, Malaysia, and South Korea, Russia, Brazil, Turkey, Argentina, and other European nations have all been involved in such crises.

The World Bank and the International Monetary Fund face moral hazard problems.

Both institutions impose conditions on borrowers that they must meet in order to receive funds.

The World Bank and the International Monetary Fund place very vague initial conditions on their loans.

By giving nations that are most likely to try to take advantage of vague conditions a greater incentive to seek funding, this policy worsens the adverse selection problem.

Basic property rights, well-run legal systems, and uncorrupt government agencies help promote growth when a developing nation has more effective institutions.

The World Bank and the International Monetary Fund should identify ways to put basic market foundations into place by guaranteeing property and contract rights.

Legal systems that can credibly enforce laws protecting these rights would need to be built.

The processes for putting capital goods in developing countries need to be simplified.

In recent years, economists have advanced a wide variety of proposals on the appropriate role for the International Monetary Fund in anticipating and reacting to international financial crises.

Many of these proposals share similar features, such as more Fund's view on its role in international financial frequent and in-depth releases of information both by the IMF and countries that crises go to borrow from this institution.

Economists recommend improved financial and accounting standards for those receiving funds from the World Bank and the International Monetary Fund, as well as other changes that might help reduce moral hazard problems in such lending.

The current structure of the International Monetary Fund should be maintained but it should be harder to develop early warning systems of financial crises so that aid can be provided to head off crises before they develop.

One proposal would create a board composed of finance ministers of member nations to be in charge of day-to-day management of the International Monetary Fund.

Government incentives, in the form of tax breaks and subsidies, are recommended for increased privatesector lending that would supplement or even replace loans made by the International Monetary Fund.

The World Bank and the International Monetary Fund confront loans to governments and private firms in developing nations.

A significant increase in the nation's per capita real GDP is currently being achieved.

Each government that fails to consistently adhere to the additional $1 billion of investment in capital goods rule of law has come to power in a developing country, and firms must pay a small fee to gain official approval for annual rate of growth.

Companies cut back their investment in order to open a range of spending to $4 billion per year.

The rate of invest $20 billion is maintained by companies if other things are employing capital resources valued at equal.

$100 million of the stocks that foreign investors decide to drop are shares that amounted to investment plans completely and less than 10 percent interest in domestic firms.

There is $10 trillion in dead capital in the world, by adverse selection and which are examples of moral hazard, if faced by international investors.

Answer the following questions about nations that failed to repay loans they received from the International Monetary Fund, but now claim to be better credit risks.

The World Bank may face moral hazard if it doesn't fully repay new loans.

The International Monetary Fund faces an adverse selection abroad.

There is a problem if it is considering making loans to the government in response to corruption in which the ruling parties have already been elected.

A small increase in the price of debit-card usage causes a reduction in the amount of transactions demanded by users.

How responsive consumers will be to changes in prices is the only way to answer these questions.

If you were told that the price elasticity of demand for oil was -1, you would know that a 10 percent increase in the price of oil would cause a 10 percent decrease in the quantity demanded.

The quantity of natural gas demanded by the United States increased from 62.21 billion cubic feet per day to 62.64 bil not very responsive to a decrease in the price.

Even a small increase in price will lead to mula for computing elasticity.

The demand curve is vertical Panel at the quantity of 8 million units per year.

The demand schedule in panel (b) is elastic because there is perfect responsiveness at each point along the curve.

The price per unit is thought to be the way for total receipts to rise.

When the price goes up to 6 cents per minute, total revenues remain constant at $3 billion.

Some important micro economic concepts are brought together by the relationship between price elasticity of demand and total revenues.

To consider how the price elasticity of demand for Internet-ready gad which of the opposing changes exerts a greater force on total revenues.

We want to come up with a list of the factors that affect the elasticity of demand.

The greater the price elasticity of demand, the closer the substitute for a particular commodity is.

In this extreme example, we are talking about two goods that the consumer believes are exactly alike and equally desirable, like dollar bills whose only difference is their serial numbers.

We can only speak about the number and similarity of the substitute when we talk about less extreme examples.

The closer we define a good, the greater the number of substitute options.

The demand for diet soft drinks may be elastic because consumers can switch to other liquid refreshments.

The elasticity of demand for a commodity is determined by the share of a person's total budget spent on it.

In contrast, the demand for items such as transportation and housing is much more elastic because they occupy a large part of people's budgets.

Consider the spending power of this family when the price of pepper and transportation double.

If transportation costs double, the family will have to spend $8,000 or $4,000 more to purchase the same quantity.

If you don't have competitors, you can't raise your price because the demand for baby food iselastic.

The inverse relationship between the short run and elasticity of demand is 1.1, even though the estimate is omitting the negative sign.

The period of time necessary for consumers to make a full adjustment to a price change is called the long run.

It will take consumers a long time to switch over to cheaper sources of heating, to buy houses and appliances that are more energy efficient, and so on, in the case of the demand for electricity.

The effect of a change in price on demand for a related good was discussed in Chapter 3.

We looked at whether a reduction in the price of one caused a decrease or increase in demand for the other.

We need to come up with a numerical measure of the responsiveness of the amount of an item demanded to the prices of related goods.

The cross price elasticity of demand will be positive when two goods are replaced.

Plans for increasing production of flash memory drives can be made.

Our understanding of elasticity can be applied to the relationship between income and demand for a good.

The longer the time period allowed for adjustment, the greater the price elasticity of demand.

The longer the time allowed for adjustment, the more resources can flow into or out of an industry.

With the operating refining equipment available to them, it will be hard for them to expand their production.

Once the equipment arrives, they can put it into place to expand their gasoline production.

Adding new refining operations can eventually respond to higher gasoline prices.

Entry or exit of firms increases or decreases production in an industry if the time allowed for adjustment is longer.

The quantity of gasoline supplied increases as new refining companies enter the market.

The time period during which full adjustment has not yet taken place is known as the short run.

Firms have been able to adjust fully to the change in price during the long run.

Steve Jobs has just made his first big Thus, although most industry observers anticipated that a pitch for Apple's latest high-tech gadget, the iPad, which can per basic iPad would be priced at $1,000, Apple.

The company has set a lower price in order to play animated figures from college textbooks.

According to media reports, industry observers think that the company will lower the price of the product in order to make more money.

The amount of satellite TV services demanded fell when they accessed using personal computers.

Section N: News is where you can find information about why cable and satellite services are viewed as imperfectly substitutable.

When a larger portion of a person's budget is spent on the good, the price elasticity of demand increases.

The percentage change in the amount of good demanded divided by the percentage change in the price of a related good is called demand price elasticity.

The good's relative price is not affected by the percentage change in income.

When sellers have more time to adjust to price changes, supply is likely to be elastic.

The demand curve for the following goods is shown in the diagram below as being close to "miniburgers" in a local fast-food market.

The range of the demand curve is based on the price of the goods and how elastic or inelastic they are.

If the price of eggs and bacon is -0.5, then the elasticity of demand to the volume of imports would be zero.

The income elasticity of things being equal, the 20 percent price increase demand for lobster, and the fact that other hot dogs is -1.25 are all indicators of the long run.

At a price of $25,000, producers of midsized auto cause a local barbershop to have its employees work mobiles to increase the number of daily haircuts cars per month.

The price elasticity of demand is a key factor in determining the use of illegal drugs, and if you make the use of certain drugs illegal, the price elasticity of demand will go up.

Why do you think the price elasticity of demand affects drug consumption?

The net result is that people are less happy with their goods and services than they would have been if they didn't use credit cards.

The human brain is thousands of times better at making choices than the computing machines available today, according to evidence.

Understanding the law of demand is useful because it allows us to examine the relevant variables, such as price, income, and tastes, in such a way as to make better sense of the world.

An analysis of consumer choice in a world of limited resources is one way to derive the law of demand.

There can't be an accurate scientific assessment of the utility that someone might receive by consuming a fast-food dinner or a movie relative to the utility that another person might receive from that same good or service.

The utility that individuals receive from consuming a good is dependent on their tastes and preferences.

No one really believes that we can measure Utils, but the ideas forthcoming from such analysis will prove useful in understanding how consumers choose among alternatives.

Let's say that there are thousands of downloadable music albums to choose from each year and that each of them is of the same quality.

If you download and listen to another music album per week, you will get more satisfaction or utility.

When a person has already downloaded and listened to two music albums in a single week, the total utility increases from 16 to 19 The marginal utility is the amount of time it takes to download and listen to one more album of Internet music after having already downloaded and listened to two in a week.

Until four digital music albums are downloaded and listened to per week, total utility continues to rise.

If we were able to assign specific values to the utility derived from download utility derived from each additional quantity, which is defined as the change and listening to digital music albums each week, we could obtain a marginal in total utility due to a change of one unit of listening to downloaded albums.

The total utility curve in panel (b) is unchanged after four albums are downloaded and listened to per week.

Rarely does a consumer face a situation of negative marginal utility.

The extra benefit law concerns a psychological or subjective utility that you receive when you decline in service.

As an individual consumes more of a particular commodity, the total level of utility, or satisfaction, derived from that consumption usually increases.

Most people experience diminishing marginal utility of food until they stop eating.

monotony in consumption was preferred instead of observing that "variety is the spice of life."

We have great confidence in the concept of diminishing marginal utility because we don't observe single-item consumption.

Newspaper vending machines are almost always nil because yesterday's news has no value.

The marginal utility is what explains the difference between the two types of vending machines.

A set of goods and services that maximize the level of satisfaction for each consumer, subject to limited income.

When total utility is maximized, the satisfaction per last dollar spent on both cappuccinos and music album downloads is equal for the two goods.

There is a table on the facing page with information on utility derived from various quantities of music album downloads and cappuccinos.

If the prices of both goods are zero, individuals will consume each as long as their marginal utility is positive, at least five units of each and probably much more.

There is no effective constraint on consumption when the price is zero or the consumer's income is unlimited.

The marginal utilities per dollar spent are equal at the consumption level of four music album downloads and two cappuccinos.

The marginal utility per dollar spent for both goods is equal to the consumption level of three music album downloads and one cappuccino, but here total income is not completely exhausted.

The marginal utility per dollar spent is equal to five music album downloads and three cappuccinos, but the expenditures necessary for that level of consumption exceed the individual's income.

Downloads and listening to the second music album yield a higher marginal utility per dollar (9, versus 8.3 for a cappuccino), so this album is also purchased, leaving an unspent income of $16.

If you buy the first cappuccino, you will get a higher marginal utility than if you listen to the next music album.

The process continues until all income is exhausted and the marginal utility per dollar spent is equal for both goods.

A consumer's money income should be allocated so that the last dollar spent on each good yields the same amount of marginal utility, because this rule yields the largest possible total utility.

People pay explicit prices for items in market settings, according to Antonio Rangel of the California Institute of Technology.

This must be true for the marginal utility per dollar spent to be equalized times, he told people.

The rule of consumer optimum can be stated in terms of the ratio of marginal utilities and prices of individual products.

Consumers' marginal utility per dollar spent on goods and services is equalized across all purchases.

Government incomes to purchase larger quantities of certain items, requirement for consumers to reallocate their incomes then the marginal utilities from consuming those items to different quantities of goods and services might please would decline.

A price increase marginal utility of the last dollar spent on one good requires consumption.

The law of demand states that the amount purchased is related to the price.

The marginal utility per dollar spent on each good or service was the same before the price change.

The marginal utility will fall because of the purchase and consumption of additional units of the lower-priced good.

At a lower price, the number of music album downloads increased from four to five.

The marginal utility is equalized across all purchases when the consumption rate is higher.

People have replaced other goods with more expensive ones in order to purchase additional smartphones as the price of their phones has fallen.

You will probably purchase more goods, including possibly even more gasoline, because you will feel richer.

When that price goes up, real income, or income effect in causing us to purchase more of goods that have become cheaper and purchasing power, falls, and when that price less of goods that have become more expensive.

The law of diminishing marginal utility and the rule of equal marginal utilities per dollar give us a negative relationship between quantity demanded and price.

The consumer can maximize total utility by purchasing more music if the price of downloads falls.

The law of demand is derived from the assumption of constant tastes and incomes.

When we look at the relationship between price and quantity demanded, we keep these important determining variables constant.

Water is cheap and diamonds are expensive, even though they are not essential to life.

Marginal utility does not determine what people are willing to pay for a unit of a commodity.

On the horizontal axis, we plot quantity in terms of kilograms per unit time period.

The horizontal quantity axis has been broken to show the demand for and supply of water.

Utility analysis makes clear predictions about how individuals will adjust their consumption of different goods and services based on the prices of those items and their incomes, which is appealing to economists.

Proponents of behavioral economics have doubts about the rationality assumption, which causes them to question the utility-based theory of consumer choice.

This assumption states that human limitations prevent people from examining every possible choice available to them and thus impede their efforts to pursue long-term personal interests.

Proponents of behavioral economics point to real-world examples that they claim violate rationality-based utility theory.

When purchasing electric appliances such as refrigerators, people sometimes buy the lowest-priced, energy-inefficient models even though the initial purchase-price savings often fail to compensate for higher future energy costs, according to economists.

People who live in earthquake- or flood-prone regions fail to purchase adequate insurance against these events.

Experiments have shown that people are willing to pay different amounts for items if they are placed in situations in which strong emotions come into play.

They argue that utility-based consumer choice theory cannot be used if the rationality assumption does not apply to actual behavior.

Utility theory is a fundamental strength of this approach and it yields clear-cut predictions regarding consumer choices.

Any number of possible human behaviors could be considered if the rationality assumption is rejected.

The "reasonableness" of rational consumers maximizing utility is likely to continue to be argued by economists.

Utilitybased consumer choice theory has allowed economists to make a wide array of predictions about how consumers respond to changes in prices, incomes, and other factors.

Key predictions are supported by actual choices that consumers make.

The demand curve needs to price a good consumer in a downward slope when the marginal utility holds.

The marginal utility of water power increases when the consumer's real purchasing increases, causing the consumer to purchase compared with the marginal utility of diamonds.

Alex Rampell operates a company called TrialPay, which is based on the principle of signing up for free trial offers.

He started his business at an optimal time for TrialPay's customers, when he was in his late 20s.

Merchants can anticipate earning future revenues from TrialPay's customers, which is why they offer a product from another firm.

The effective price of a TrialPay "freebie" is greater than that of a movie service.

The marginal utility experienced from the TrialPay Web cover is very low, so what does Netflix think the dollar value of the time and effort will be spent on?

The economists suggest that the decision that many people make to use credit cards is a good example.

They suggest that people use optimum in which positive marginal utility per dollar spent their cards to obtain too many items.

As the person consumes more and more of the good or service, marginal utility declines.

Consumption Choices per dollar spent on the last unit consumed is equalized.

It is possible to analyze consumer choice in a way that is1-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-65561-6556 On intuitive grounds, the theory of diminishing marginal utility can be accepted.

We show consumer equilibrium in geometric form by discussing these terms and their relationship.

In panel (a) of Figure F-1 below, we show several combinations of fast food and movie tickets that a representative consumer considers equally satisfactory.

We have used a simple example to show how fast-food and movie theaters affect a consumer's weekly budget.

A curve composed of a set of consumption every combination of the two goods in question yields the same level of satisfaction.

It doesn't seem plausible that a consumer is willing to give up one fast-food meal per week to watch a movie.

The indifference curve in panel (b) of Figure F-1 will be different when viewed from the origin.

If we rearrange panel (a) of Figure F-1 on page , we can see what happens to the marginal rate of substitution.

A three-unit decrease in fast-food meals requires an increase of one movie ticket to leave the consumer's total utility unaffected.

The marginal rate of substitution is measured by the slope of the consumer's indifference curve.

An indifference curve will have to be drawn below and to the left of the one in panel (b) of Figure F-1 if the individual faces the possibility of having less of both movie tickets and fast-food meals per week.

The higher an indifference curve is for a consumer, the greater their total level of satisfaction.

The budget line's anchor points are obtained by dividing money income by the price of each product.

The two optimum points are given by the indifference curve that just touches the two budget lines.

In panel a, we show the effects of a decrease in the price of movie tickets from $10 to $5.

The demand curve for tickets to movies slopes downward when we connect these two points.

As one moves down the indifference curve, the marginal rate of substitution falls.

Consumer optimum Figure F-5, 457 is obtained when the highest feasible indifference curve is just outside the budget constraint line.

The budget constraint is the rate of exchange between two goods, which is the ratio of their dollar prices.

The budget line rotates due to the price of an item in Study Plan 20.13.

The curve is convex to the origin in economic goods that satisfy Sue's utility maximization terms.

Sue's budget can be increased by two soft drinks and three hamburgers by using the indifference curve diagram.

As shown in the table below, Sue's constant-utility preferences are indifferent between two soft drinks and three, if your classmate states that he is also Problem F 3.

If Sue's son can have these preferences, use your diagram from part (a) to show him the combination of goods that satisfy him.

The table shows Sue's preferences for bottled water and soft drinks.

The rate of substitution to marginal utility is determined by the answers to Problems F-5 and F-7.

Explain the difference between accounting profits and economic profits after the Great Crash of wak, and how the interest rate performs when average stock prices plummet.

Economic rent can be applied to other factors of production, such as land and natural resources.

Some of the people who provide different labor services are likely to receive large amounts of economic rent.

Today's most highly paid entertainment figures receive economic rent because no one can duplicate them.

Entrepreneurs, managers, and workers make up the organizational structure of a typical firm.

Entrepreneurs combine land, labor, and capital to make a good or a service.

Some economists believe that the true quality of anentrepreneur can be seen with the selection of managers.

Managers decide who should be hired and fired and how the business should be run on a day-to-day basis.

The workers use the other inputs to make the products and services that the firm sells.

Close to 72 percent of firms in the A business are owned by one individual in the United States, as shown in Table 21-2 above.

Each is owned by a single individual who makes the business decisions, receives all business decisions, receives all the profits, and is legally responsible for the debts of the firm.

It is possible to seize the second disad of the owner of a firm in order to get a large sum of money from the lender.

As shown in Table 21-2 above, partnerships are less numerous than businesses owned by two or more partners.

A legal entity can conduct business because they own shares in the firm.

The corporation's existence does not depend on the life of any one of the firm's owners, as people are able to buy ownership shares or lend funds to the corporation knowing that their liability is limited to the amount of funds they invest.

Law firms in the United Kingdom were given the authority to restructure liability in 2011.

They are measured by out of pocket and not what the resources currently used in producing a particular good or explicitly calculate, such as the opportunity service could earn in other uses.

The opportunity cost of the labor that the proprietor provides to the business is what causes single-owner proprietorships to grossly exaggerate their profit rates.

If they had worked for someone else in a similar job, they would have figured into their costs the salary they could have made.

He is incurring losses in an economic sense unless his service station shows accounting profits of more than that per week.

After only explicit U.S. annual revenues and expenses, accounting profit ends up being the residual.

Remember that implicit costs include a normal rate of return on invested capital.

The basis for the analysis was provided by the theory of consumer demand, utility maximization by the individual.

The goal of the firm is to maximize economic profits, and the firm is expected to make the positive difference between total revenues and total costs as large as it can.

Firms that can provide relatively higher risk-corrected returns will have an advantage in obtaining financing needed to continue or expand production.

It is expected that a policy of profit maximization will become the dominant mode of behavior for firms that survive.

Each partner's liability for the debts of the firm is not included as a cost when accounting profits.

Funds used to purchase physical capital in physical capital and rights to patents and trademarks from which they hope to goods, such as buildings and equipment, and make a satisfactory return.

The annual interest rate is 5 percent if you pay me back at the end of the year.

You will find that the interest rate charged is vastly different when you go into the marketplace for credit.

A loan to buy a house can cost you up to 6 percent in annual interest.

It is possible to pay less than 4 percent in annual interest on Treasury securities.

The rate of annual interest that must be paid depends on a number of factors.

The interest rate charged is related to the risk of nonrepayment of the loan.

If the borrower fails to comply with the loan agreement, the asset will become the lender's property.

A price that allocates credit to consumers and businesses is called interest.

If the expected rate of return on the purchase of a new factory or intellectual property is 10 percent, the investment project will proceed.

The interest rate allocates funds to industries with the highest risk-adjusted returns.

The interest rate allocates real physical capital to various firms for investment projects, and it is important to realize that the interest rate performs the function of allocating financial capital.

Businesses incur large costs today but don't make a profit until some time in the future.

If you have to pay $105 at the end of the year when you borrow $100, that 5 percent interest rate gives you a measure of the premium on the earlier availability of goods and services.

If you want to have things today, you have to pay a 5 percent interest rate.

The formula for figuring out the worth of dollars to be received in the future can now be determined.

The present value of $1 will be received in future years at var ious interest rates.

Why did a number of U.S. corporations suddenly report significant reductions in sums back to present value?

The new law reduced the amount that com panies' discounted present value of anticipated after-tax profits can deduct from their federal income taxes.

The Dutch East India Company raised financial capital by selling shares of its future profits to investors.

The company issued notes of indebtedness, which involved borrowing funds in return for interest paid on the funds, plus eventual repayment of the principal amount borrowed.

The methods of financing used by the Dutch East India Company four centuries ago are still used today.

If you give up your voting rights, you will get preferential treatment in the payment of dividends.

Roughly 75 percent of new financial capital for corporations in recent years has come from reinvestment by established firms, which is an important source of financing.

Small businesses can't rely on the stock market to raise investment funds.

This title has been held by the National Association of Securities Dealers Automated Quotations since the mid-2000s.

The market links 500 dealers and is home to nearly 4,000 stocks, including those of Microsoft, Intel, and Cisco.

At any point in time, tens of thousands, even millions, of people are looking for information that will allow them to forecast the future prices of stocks.

The result is that all publicly available information that might be used to forecast stock prices gets taken into account by those with access to the information and the knowledge and ability to learn from it, leaving no predictable profit opportunities.

Information that is not available to the general is in charge of new product development at the world's largest software firm, Microsoft.

You could make a lot of money by buying shares of Microsoft and selling them at a higher price when the new product is announced.

Stock trading based on inside information is illegal and can result in fines and even imprisonment.

If you have a way the Securities and Exchange Commission tries to prevent the use of inside stronger-than-average desire for a long vacation in a federal prison, you might be better information.

It is possible for people to influence stock or bond prices through the accidental release of inside information.

The information of the bond's demise would be made public at 10 a.m., according to Treasury officials.

The officials told reporters in advance that they would have time to write stories at the later hour.

The officials decided that members of the commission's own staff failed to report that it would be prudent to put into place the kinds of monitoring systems stock trades.

The SEC discourages staff members from trading the stocks of firms that it might bring charges against because it encourages them to do so.

The three primary sources of corporate funds make a higher-than-normal rate of return.

The answer is that the city faces an even higher homeless rate because of the present value of anticipated future expenses.

Paying for the market price of a plane ticket that the city government will give to the homeless is the lower-cost alternative.

The stock market crash of 1929 and the Great Depression of the 1930s have been compared to the downturn in average U.S. securities prices that occurred in the late 2000s.

If you had held stocks with a market value of $10,000 or less in price decline, it was likely that it would be compared to how 1929 crash in severity was.

The downturn that followed the Great Crash of 1929 has been shown to be less like the stock price meltdown of the late 2000s.
