AP Microeconomics Unit 5: Factor Markets - Labor Dynamics

Derived Demand

The demand for labor driven by the demand for the goods or services that labor produces.

Marginal Product (MP)

The additional output generated by adding one more worker.

Marginal Revenue Product (MRP)

The additional revenue generated by adding one more worker, acting as the Demand Curve for Labor.

Marginal Resource Cost (MRC)

The additional cost incurred by hiring one more worker, often equated to the wage.

Profit Maximization Rule

A firm will hire workers as long as the revenue generated by the worker (MRP) is greater than or equal to the cost of hiring them (MFC).

Wage Taker

A firm in a perfectly competitive labor market that cannot influence the market wage.

Monopsony

A market structure where there is only one buyer of labor, functioning as a wage maker.

Labor Demand Curve ($D_L$)

A curve that shifts based on changes in product demand, productivity, or prices of related resources.

Efficiency in Labor Market

When labor is allocated optimally, balancing the valuation of labor output against its cost.

Deadweight Loss

The loss in economic efficiency that occurs when the equilibrium for a good or service is not Pareto optimal.

Change in Product Demand

One of the main factors impacting the demand for labor, where an increase in product price increases worker value.

Change in Productivity

A shift in labor demand resulting from improvements in worker efficiency or technology.

Equilibrium Wage ($W_e$)

The prevailing wage rate determined by the intersection of supply and demand in a labor market.

Immobile Labor

A characteristic of monopsony where workers cannot easily move to different jobs or regions for better wages.

Wage Maker

A firm that can influence the wage it pays, typically seen in monopolistic markets.

Law of Diminishing Marginal Returns

The principle stating that as more units of a variable factor are added to a fixed factor, the additional output produced will eventually decrease.

Labor Market Analysis

The examination of how supply and demand dynamics influence wages and employment levels in the labor market.

Cost-Benefit Analysis (Marginal Analysis)

A method firms use to determine the optimal number of workers to hire by comparing the marginal cost and marginal revenue.

Supply Curve in Labor Market

In a perfectly competitive market, this curve is horizontal indicating that the wage is constant regardless of the quantity of labor supplied.

Substitutes and Complements

The relationship between goods that can either replace each other (substitutes) or are used together (complements), influencing labor demand.

Firms Demand Labor

Refers to the behavior of businesses seeking to employ workers to produce goods and services.

Households Supply Labor

Indicates that individuals offer their time and effort as labor to firms in the market.

Shifters of Labor Demand

Factors that cause labor demand to shift, including product demand, productivity, and prices of related resources.

Marginal Factor Cost (MFC) higher than Wage

A phenomenon in monopsonistic markets where the cost of hiring additional labor exceeds the wage paid.

Market vs. Firm Labor Hiring

In a competitive market, hiring decisions reflect the market equilibrium, while in a monopsony, hiring reflects the firm's wage setting.
