Heated debate, - Article ExampleRossi-Hansberg of Princeton University in their working paper are inquire whether there are ways of managing the impact of changing weather patterns by moving the location of economic activity. These writers note that about 90% of international production makes use of only 10% of the land available. When that 10% is threatened, activity may at least theoretically shift to bits of the 90% made more hospitable by climate change.Thus Messrs Desmet and Rossi-Hansberg created a model economy and battered it with various temperature rises to gauge its reaction. In this analysis, the two writers allow people to move near as they want in this response. In worst situations, freedom from movement does not make much difference since temperatures lead to a reduction of global agricultural productivity to almost zero, meaning the end of human life on earth. Neverthe slight, in more moderate situations, rising global temperatures elicit agricultural productivit y in northerly climes. Restrictions on movement on the other hand, dramatically increase the cost of welfare. This model is simplistic and suggests that limits on migration let a huge impact on the global warming costs. Mr. Mathew Kahn (University of California) claims that warming of the climate, will lead to vulnerable areas such as lower Manhattan to become less desirable in relation to rival centres such as New Yorks suburbs, Manhattan and Chicago. It is therefore important that rational firms and workers to assess the dangers of floods or such and migrate, so as to raise the productivity of the destination locations as they appear. This move would come with its own costs and investors in places such as lower Manhattan property would for case suffer big losses. Nevertheless Mr. Kahn argues that there may also be gains as activity shifts from ancient cities to more modernized areas.The conclusion of the article points to political sympathies involvement through such things as food flood insurance, for those living
