- Give typing answer with explanation and conclusion Suppose that the government must undertake an irreversible policy decision regarding the extent of air pollution regulation. The government is making this decision in a situation of uncertainty, however. In particular, there is some probability p that the benefits will remain the same as they are this year for all future years, but there is some probability 1 - p that benefits will be less in all future years. If we take into consideration the multiperiod aspects, should we err on the side of overregulation or underregulation, compared to what we would do in a single-period choice?10 10Can you Do it fast.

- The problems with e.g."Acid rain" created by emissions of sulfur dioxide has been onemajor problem in Sweden, not least because emissions have occurred in other countries (eg England and Denmark) andthen transported here. Now assume that if one tonne of sulfur is emitted in England, it results in one (1) gram of sulfur deposition in Sweden. The corresponding deposit of one tonne of sulfur emissions in Denmark is assumed to be 3 grams. Suppose further that The socio-economic damage of one gram of sulfur deposit can be estimated at SEK 0.10.The marginal cost of reduce sulfur emissions in England is estimated at Z SEK per tonne, and in Denmark the equivalent is estimatedcost to 2Z SEK per tonne. Z indicates here the emission reduction in tonnes (eg in Denmark it would cost SEK 4 toreduce emissions by two tonnes). In other words, Z = 0 corresponds to the emission level where there is no reductionemissions occur. a) Suppose now that the European Union decides that Denmark and England…10 7Can you Do it fast.

- The town of Whoopup has decided that it needs a new public library. Although the city leaders have made this decision, the decision of location of the library is still an open question. Knowing that you have a back ground in economic decision making, they selected you to formulate their decision problem. You gather data from the city leaders to determine the important attributes to consider in the decision; you then acquire information for both sites and present it in teh shown Table . Use the tools introduced in this chapter to make a site recommendation.
