Consider a typical graphical model of market supply and demand as applied to the market for two endangered species products: rhino horn and elephant tusk (two separate markets). a global ban on the trade of endangered species products has been imposed. this is likely to affect both the demand and the supply for both products. the demand for rhino horn is relatively inelastic, since relatively few close substitutes exist. the demand for elephant tusk is relatively elastic, since good substitutes exist. a. graphically illustrate in which market you would expect a ban to be successful and explain why? b. what alternatives to a ban are there that might improve the effectiveness of the policy to reduce the trade in endangered species products?

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.

Bdj co. wants to issue new 22-year bonds for some much-needed expansion projects. the company currently has 9.2 percent coupon bonds on the market that sell for $1,132, make semiannual payments, have a $1,000 par value, and mature in 22 years. what coupon rate should the company set on its new bonds if it wants them to sell at par?

Suppose that electricity producers create a negative externality equal to $5 per unit. further suppose that the government imposes a $5 per-unit tax on the producers. what is the relationship between the after-tax equilibrium quantity and the socially optimal quantity of electricity to be produced?
