Two factories dump industrial waste into a stream. They can reduce their waste (abate), but it is costly. The Marginal Cost of Abatement (MCA) for factory 1 is 10 + 2A1, and for factory 2 is 5 + A2, where Ai is the amount of pollutants that have been abated. The municipal government has opted for a Cap and Trade policy. The cap effectively requires the firms to reduce total pollution by 30 units. Permits are issued to Firms 1 and 2 such that Firm 1 will have to abate by 10 units and Firm 2 will have to abate by 20 units. a)If trade of permits is not allowed, what will be the costs of abatement to each firm?b) If trade of permits is allowed, what will be the abatement and marginal cost levels for eachfirm? c)What will the total cost of abatement be after trade of the permits?d) If we assume that all permits are bought/sold at the marginal cost you found in part b), whatwill be the net abatement costs for each firm?

David paid $975,000 for two beachfront lots in coastal south carolina, with the intention of building residential homes on each. two years later, the south carolina legislature passed the beachfront management act, barring any further development of the coast, including david's lots. when david files a complaint to seek compensation for his property, south carolina refuses, pointing to a passage in david's own complaint that states "the beachfront management act [was] properly and validly designed to south carolina's " is south carolina required to compensate david under the takings clause?
