Taxes and Welfare

This set of flashcards is designed to help students review key concepts regarding taxes and welfare from the lecture notes.

Welfare from Tax

The concept that analyzes the impact of taxes on consumer surplus (CS) and producer surplus (PS).

Dead Weight Loss (DWL)

The fall in total surplus resulting from market distortions like taxes, monopolies, and price controls.

Elasticity

A measure of how responsive the quantity supplied or demanded is to a change in price.

Dead Weight Loss and Elasticity

DWL increases as the price elasticity of supply or demand increases, and a more inelastic good results in less DWL.

Tax Revenue

The income generated from collecting taxes, which contributes to total surplus under taxation.

Laffer Curve

Illustrates the relationship between the size of tax and tax revenue, demonstrating that revenue can peak at an optimal tax rate.

Consumer Surplus (CS)

The difference between what consumers are willing to pay and what they actually pay, represented graphically as areas A, B, C.

Producer Surplus (PS)

The difference between what producers are willing to sell for and the market price, represented graphically as areas D, E, F.

Market Distortion

Occurrences that lead to a departure from free market equilibrium, often resulting in dead weight loss.
