hi ,

i need a help in my home work in economy :

1-The New York Times reported (Feb. 17, 1996, p. 25) that subway ridership declined after a fare increase: "There were nearly four million fewer riders in December 1995, the first full month after the price of a token increased 25 cents to $1.50, than in the previous December, a 4.3 percent decline." a. Use these data to estimate the price elasticity of demand for subway rides.

b. According to your estimate, what happens to the Transit Authority's revenue when the fare rises?

c. Why might your estimate of the elasticity be unreliable?

2-Two drivers—Tom and Jerry—each drive up to a gas station. Before looking at the price, each places an order. Tom says, "I'd like 10 gallons of gas." Jerry says, "I'd like $10 worth of gas." What is each driver's price elasticity of demand?

3- Pharmaceutical drugs have an inelastic demand, and computers have an elastic demand. Suppose that technological advance doubles the supply of both products (that is, the quantity supplied at each price is twice what it was).

a. What happens to the equilibrium price and quantity in each market?

b. Which product experiences a larger change in price?

c. Which product experiences a larger change in quantity?

d. What happens to total consumer spending on each product?

4- Several years ago, flooding along the Missouri and Mississippi rivers destroyed thousands of acres of wheat.

a-Farmers whose crops were destroyed by the floods were much worse off, but farmers whose crops were not destroyed benefited from the floods. Why?

b. What information would you need about the market for wheat in order to assess whether farmers as a group were hurt or helped by the floods?

5- Because better weather makes farmland more productive, farmland in regions with good weather conditions is more expensive than farmland in regions with bad weather conditions. Over time, however, as advances in technology have made all farmland more productive, the price of farmland (adjusted for overall inflation) has fallen. Use the concept of elasticity to explain why productivity and farmland prices are positively related across space but negatively related over time.
