تمرين 25

Suppose there are three people in society who vote on whether the government should undertake specific projects. Let the net benefits of a particular project be $150, $140, and $50 for persons A, B, and C, respectively.
a. If the project costs $300 and these costs are to be shared equally, would a majority vote to undertake the project? What would be the net benefits to each person under such a scheme? Would total net benefits be positive?
b. Suppose the project cost $375 and again costs were to be shared equally. Now would a majority vote for the project and total net benefits be positive?
c. Suppose (presumably contrary to fact) votes can be bought and sold in a free market. Describe what kinds of results you might expect in part a and part b.
