2. The following table shows how the marginal benefit enjoyed by Amy, May, Lisa, and all other consumers of Science Exhibitions varies with the number made available by a city government per summer. a. Derive the demand curve for Science Exhibitions assuming that it is a pure public good. b. If the marginal cost of producing Science Exhibitions is $2,500 no matter how many are produced, then what is the efficient number of exhibitions to have each summer? What would be the efficient number of exhibitions to produce if the marginal cost of production were $850 instead of $2,500? c. Suppose the marginal cost of producing Science Exhibitions is only $500 per exhibition no matter how many are produced. Use the data below to calculate the efficient number of exhibitions. If a Lindahl scheme is used to finance the exhibition, what prices of admission should be charged to Amy, Lisa, and May? Marginal Benefit of Number of Science Exhibitions per Consumer (in $) CONSUMERS 1 2 3 4 Amy 250 250 200 150 May 225 200 150 100 Lisa 200 150 100 50 All others 1200 800 400 200
