Benefits principle people should pay taxes based on the benefits they receive the bigger the distortionary effects the higher the elasticity. Cped (cross price elasticity of in price (b) demand) formula. Elasticity/ the price sensitivity of a good equation. Club goods non-rival and excludable (cable tv, national parks, movies) government intervenes to keep incentives up. Coase theorem two parties bargain and arrive at the social optimal quantiity without government intervention. Common resource goods rival and non-excludable (lumber, the ocean) will always lead to over consumption without government intervention completely unrelated goods (closer to. The maximum price you can afford a certain bundle, it is when the bundle only touches the indifference curve once. Per-unit taxes or subsidies aimed at shifting the private curves until they mirror the social curves, shift the demand curve to the left.
