Suppose a state is considering improving river water quality downstream from a wastewater treatment facility. the water quality is indicated by q, with initial quality q = 0. the beneficiaries of an improvement are (i) 100 people who fish, who each have demand for water quality given by q = 100 − 2p; and (ii) 50 people who boat, who each have demand q = 30 − p. the (total) social cost of improving the wastewater treatment is t sc = 1500q + 50q 2 . (a) what is the equation for the marginal social benefit of improvements in water quality, q? (b) what is the equation for the marginal social cost of q? (c) what is the efficient improvement in water quality for the state to choose? (d) what is the net social benefit of the improvement in (c)? illustrate and calculate a number. (e) do the people who boat and the people who fish value the last unit of improvement in water pollution the same amount or different amounts? what is each group’s marginal valuation of water pollution at the efficient quantity

Peppy roaney believes that pizza is a much more versatile dish than most people realize. as the national marketing manager for pizza guys, he observed how consumers were delighted with barbecue pizza, hawaiian pizza, mexican pizza and other unique combinations. his suggestions for other unusual pizzas, however, were met with a negative response by his superiors. even some of his colleagues laughed at his ideas. peppy's confidence in his ability to understand the market has led him to focus on planning a business of his own. peppy realizes that he will take a risk when he leaves his job with pizza guys and embarks upon a new venture: peppy's pizzazzeria. peppy is excited about the potential of profitably catering to the unmet desires of pizza consumers. peppy is confident that peppy's pizzazzeria will be a success, but only if he has enough money to do things right. since peppy has very little personal wealth, he knows he must obtain financial assistance. in order to prepare for meetings with bankers and p

Recently, verizon wireless ran a pricing trial in order to estimate the elasticity of demand for its services. the manager selected three states that were representative of its entire service area and increased prices by 5 percent to customers in those areas. one week later, the number of customers enrolled in verizon's cellular plans declined 4 percent in those states, while enrollments in states where prices were not increased remained flat. the manager used this information to estimate the own-price elasticity of demand and, based on her findings, immediately increased prices in all market areas by 5 percent in an attempt to boost the company's 2016 annual revenues. one year later, the manager was perplexed because verizon's 2016 annual revenues were 10 percent lower than those in 2015"the price increase apparently led to a reduction in the company's revenues. did the manager make an error? yes - the one-week measures show demand is inelastic, so a price increase will decrease revenues. yes - the one-week measures show demand is elastic, so a price increase will reduce revenues. yes - cell phone elasticity is likely much larger in the long-run than the short-run. no - the cell phone market must have changed between 2011 and 2012 for this price increase to lower revenues.
