Suppose that in a particular market, the demand curve is highly elastic and the supply curve is highly inelastic. If a tax is imposed in this market, then a. the buyers will bear a greater burden of the tax than the sellers. b. the sellers will bear a greater burden of the tax than the buyers. c. the buyers and sellers are likely to share the burden of the tax equally. d. the buyers and sellers will not share the burden equally, but it is impossible to determine who will bear the greater burden of the tax without more information. 2

Table 11-1 Consider the town of Tritown with only three residents, Ed, Jim, and Tony. The three residents are trying to determine how large, in acres, they should build the public park. The table below shows each resident s willingness to pay for each acre of the park. Acres Ed Jim Tony 1 $12 $16 $ Refer to Table Suppose the cost to build the park is $30 per acre.
