Vocabulary flashcards covering welfare economics, efficient market outcomes, demand curve interpretations, and consumer surplus concepts from Chapter 7.

Principle 6

Principle 7

The principle stating that governments can sometimes improve their market outcomes.

Efficient Market Outcome

A market outcome that does not involve any misallocation of resources (such as labor, capital, land, and ambient air/environment), where the equilibrium output level ($Q^*$) and equilibrium price ($P^*$) maximize the economic welfare of society as a whole.

Welfare Economics

The area of economics that focuses on the study of the allocation of resources and its effect on economic wellbeing.

Point on a Demand Curve

A point showing the maximum price a consumer is willing to pay for a particular unit of a good.

Market Price ($P^*$)

The price a consumer actually pays when buying a unit of a good in question.

Consumer Surplus for a Unit of a Good

A consumer's net gain from buying a unit of a good, calculated as the amount a buyer is willing to pay minus the amount actually paid ($\text{MWTP} - P^*$) when $\text{MWTP} \boldsymbol{\beta} P^*$, and equal to $0$ when $\text{MWTP} < P^*$.

Total Consumer Surplus

The sum of the consumer surplus derived from each unit of a good bought by a single consumer.

Market Consumer Surplus

The sum of each consumer's total consumer surplus in a given market.

Implicit Form of Savings

An interpretation of consumer surplus representing the monetary savings a consumer realizes by paying a market price lower than their maximum willingness to pay.

Total Consumer Surplus on a Demand Curve Graph

The geometric area located below the demand curve and above the market price line.
