When Elle's Espresso Bar raised its price by 10 percent, the quantity of coffee that Elle sold decreased by 40 percent. When Elle and all her competitors cut their prices by 10 percent, the quantity of coffee sold by Elle increased by only 4 percent.Explain the difference between the responses to Elle's price hike and the price cut. Why did the price increase bring a large response in the quantity sold while the price cut had only a small effect?
A. Elle's coffee has lots of close substitutes while coffee has few substitutes, so the demand for Elle's coffee is more elastic than the market demand for coffee.

Oil prices rise ahead of OPEC meetingThe Organization of the Petroleum Exporting Countries (OPEC) produces about 40 percent of the world's output of crude oil. With the global demand for oil falling, OPEC has cut production in an attempt to stop the price sliding further from its high of $147 a barrel. OPEC knows that to raise the world price of oil it has to cut the total production of its member countries.OPEC also knows that the demand for crude oil is inelastic. Is it possible to conclude from these facts that OPEC's total revenue would increase if it were to cut its production?
No because non-OPEC oil producers can increase production, which lowers the price.
Valentine RosesOn Valentine's Day 2015, 257 million roses were sold for about double the normal price. On a normal day, 3 million roses are sold.Source: aboutflowers.com, 2015What is the magnitude of the elasticity that you can estimate using the information provided?If we assume that, by using the midpoint method, the percentage change in the price is 100 percent, then the _______.
On Valentine's Day the demand for roses increases.The demand curve shifts rightward and the change in the quantity bought and sold is equal to the change in the quantity supplied.The price elasticity of supply is equal to the percentage change in the quantity supplied divided by the percentage change in the price.The average quantity sold is (3 million + 257 million) divided by ÷2, which is 130 million.When the quantity sold increases from 3 million to 257 million, the percentage change in the quantity supplied is [(257 millionminus−3 million) divided by ÷130 million] times ×100, which is 195 percent.The percentage change in price is 100 percent.The price elasticity of supply is 195 percent divided by ÷100 percent, which is 1.95.
As gas costs soar, buyers are flocking to small cars Faced with high gas prices, Americans are substituting smaller cars for SUVs. In April 2008, Toyota Yaris sales increased 46 percent and Ford Focus sales increased 32 percent from a year earlier. Sales of SUVs decreased by more than 25 percent in 2008 and Chevrolet Tahoe sales fell 35 percent.
