Travis Kellenberger AGEC 700 Problem Set #3 2) The demand curve for a product is given by Qdx = 1‚200-3Px- .01Pz‚ where Pz = $300. a) What is the own price elasticity of demand when Px = $140? Is demand elastic or inelastic at this price? What would happen to the firm’s revenue if it decided to charge a price below $140? At the given prices‚ quantity demanded is 750 units: Qdx = 1‚200- (3 *140) -.1 (300) = 750. -140/750=-.56; demand is inelastic at this price point and you would be decreasing

z-statistic z=Q-μσ=32‚000-25‚00010‚000=0.7 We then look up the standard normal loss function. The expected lost sale is given by. Lz=0.1429 Therefore‚ the expected lost sales = 10‚000 * 0.1429 ≈ 1‚429 Expected sales = 30‚000 – 1‚429 = 30‚571 jerseys 3. First‚ we normalize the order quantity to find its z-statistic z=Q-μσ=28‚000-20‚00010‚000=0.8 In-stock probability = normdist(0.8‚ 0‚ 1‚ 1) = 0.788145 Therefore‚ the probability of filling all demand is 0.788145 4.

Econ Answers Chapter 3 The price of train travel increases by 10% and the demand for train travel falls by 12.5%. The price elasticity of demand for train travel is – -1.25 The short run (retail) supply of freshly cut flowers is much less elastic than that of pot plants because: -florists cannot keep freshly cut flowers as long as pot plants If demand drops to zero at the slightest increase in price‚ demand is: - Perfectly elastic Price elasticity of supply will be greater when: - firms hold large
