1) The Herfindahl index Suppose that three firms make up the entire tire manufacturing industry. One has a 50% market share, and the other two have a 25% market share each.
The Herfindahl index of this industry is .
2) Tread Tough, one of the firms with a 25% market share in the tire manufacturing industry, leaves the market.
This would cause the Herfindahl index for the industry to .
3) The largest possible value of the Herfindahl index is 10,000 because:

a) An index of 10,000 corresponds to 100 firms with a 1% market share each.
b) An industry with an index higher than 10,000 is automatically regulated by the Justice Department.
c) An index of 10,000 corresponds to a monopoly firm with a 100% market share.

The market price of cheeseburgers in a college town increased recently, and the students in an economics class are debating the cause of the price increase. some students suggest that the price increased because the price of beef, an important ingredient for making cheeseburgers, has increased. other students attribute the increase in the price of cheeseburgers to a recent increase in college student enrollment.1. the first group of students thinks the increase in the price of cheeseburgers is due to the fact that the price of beef, an important ingredient for making cheeseburgers, has increased. (what happened to demand and supply, shift to the right or left)2. the second group of students attributes the increase in the price of cheeseburgers to the increase in college student enrollment. (what happens to demand and supply, shift to the right or left)3. suppose that both of the events you analyzed above are partly responsible for the increase in the price of cheeseburgers. based on your analysis of the explanations offered by the two groups of students, how would you figure out which of the possible causes was the dominant cause of the increase in the price of cheeseburgers? (choose a, b,c, or d)a)if the price increase was small, then the supply shift in the market for cheeseburgers must have been larger than the demand shift.b)if the equilibrium quantity of cheeseburgers decreases, then the demand shift in the market for cheeseburgers must have been larger than the supply shift.c)if the equilibrium quantity of cheeseburgers decreases, then the supply shift in the market for cheeseburgers must have been larger than the demand shift.d)whichever change occurred first must have been the primary cause of the change in the price of cheeseburgers.
