ECON 1 Lecture Notes - Lecture 27: Normal Good, Marginal Cost, Economic Equilibrium
Document Summary
Disequilibrium: temporary mismatch between quantity supplied and quantity demanded as the market seeks equilibrium. Price floors: a minimum selling price that must be above equilibrium price to have an impact. Price ceilings: a maximum selling price which must be set below equilibrium price to have an impact. Lo1: define and graph the price elasticity of demand. Price elasticity of demand: how responsive consumers are to a change in price. Quantity demanded is relatively unresponsive to a change in price. Formula: q / p . (q+q")/2 (p+p")/2. If price decline inelastic, total revenue decreases. Consumers are more responsive to a given price change when the initial price is high than its low. Demand becomes less elastic as we move down the curve. Constant-elasticity demand curves: elasticity is same all along the curve. Price is no object, price change has no effect on quantity demanded. Percent change in price cause an exact opposite percent change in.
