Managerial Econ – Formula/Concept Sheet Taxes – no matter whether tax is on consumer or producer, the end final equilibrium outcome is the same. Imposed on the customers, demand shift . On sellers, supply shift Elasticity: Price Elasticity of demand (point elastisticity): = EPD PQ∙dQdP If many substitute goods are available, then demand is price elastic. Arc Elasticity : = - - ED Q2 Q1Q1P2 P1P1 Income Elasticity of Demand: = EY YQ∙dQdY Consumer Behaviour Complete (rank market baskets/bundle), Transitive (eg. I like A->B, B->C, C->A), prefer more to less (non- satiation). Indifference curve always slope downward, cannot cross each other, further from origin = better MRS (Marginal Rate of Substitution) – Measured by slope of indifference curve. – how willingly people trade 1 gd for the other – MRS decreases as we move along the curve…. diminishing MRS 1.)
