Eric Sjöberg, one of the Mistra Arctic Futures:Arctic Games project participants, will defend his thesis towards a degree of Doctor in Philosphy in Economics at Stockholm University on 17 October 2013. He will be the first PhD student from the Mistra Arctic Futures programme to graduate. Sjöberg’s thesis consists of three different papers that can be summarized as follows. In The political economy of environmental regulation he studies how enforcement of national environmental legislation differ across municiplaities in Sweden depending on the local political situation. While the legislation is national, enforcement is decentralized. He finds that municipalities where the Green Party has joined the ruling political coalition issue more environmental fines than other municipalities. In Pricing on the fish market he uses Swedish data to study how size affects the price per kilo of fish for several species. In traditional fishery biomass models, fish sticks are treated homogenous. New theoretical heterogenous fishery models, where size is allowed to differ in a fish stock, have important implications for regulation, for example that it is optimal too regulate on numbers of fish rather than weight. However, prices in these modes are assumed to be constant. His estimates can be used to shed some light on how prices change when the size and composition of the catch changes. In his third and final chapter, the work on the Arctic Games project features particularly strongly. In Settlement under the threat of conflict- The cost of asymmetic information, he presents a theoretical model where two players can divide a good peacefully or engage in a contest in order to obtain the entire good. He assumes that one player’s valuation of the good is private information and show how this affects the expected cost of the contest and thus the probability of peaceful settlement.
