Chapter 19 - Supply/Demand Elasticity Flashcards
price elasticity of demand equation (Ep)
Ep = %Quantity / %Price
responsiveness of quantity demanded of a commodity to changes in its price
price elasticity of demand
percentage change in quantity demanded is larger than the percentage change in price
elastic demand
Ep > 1 means blank
elastic demand
percentage change in quantity demanded is smaller than the percentage change in price where Ep < 1
inelastic demand
zero elasticity is a blank line
straight vertical
perfect elastic line is blank
straight horizontal
closer the substitutes and the more substitutes there are, the more blank is demand
elastic
the greater the share of the consumer’s total budget spent on a good, the greater is the blank
price elasticity
two determinants of price elasticity of demand
existence of substitutes, share of the budget
cross price elasticity of demand equation
Exy = % change in amount of good X demanded / % change in price of good Y
substitutes would result in a blank cross price elasticity of demand
positive
complements would be blank in the cross price elasticity of demand
negative
percentage of change in demand for any good holding its price constant, divided by the percentage change of income
income elasticity of demand
the responsiveness of the quantity supplied of a commodity to a change in its price
price elasticity of supply
