Unit 1: Decision Making and Economic Structures

Marginal Analysis

A tool used to determine if choices are rational by comparing marginal benefits to marginal costs.

Marginal Benefit (MB)

The additional satisfaction or utility derived from consuming or producing one more unit of a good or service.

Marginal Cost (MC)

The additional cost incurred from consuming or producing one more unit of a good or service.

Optimal Quantity

The level of an activity where marginal benefit equals marginal cost (MB = MC).

Law of Diminishing Marginal Utility

As consumption increases, the satisfaction gained from each additional unit generally decreases.

Command Economy

An economic system where the government or a central authority owns resources and makes all decisions.

Market Economy

An economic system where individuals and private firms own resources and make decisions through voluntary exchange.

The Invisible Hand

A concept by Adam Smith that describes how self-interested behavior in free markets leads to efficient outcomes.

Mixed Economy

Consumer Wants

Optimal Level

The point at which the total net benefit is maximized, often where marginal cost equals marginal benefit.

Economic Equity
