First, we have applied a static framework for the assessment of economic impacts of the Öresund bridge. Secondly, we make an attempt to enhance the static framework through the introduction of economic dynamics. Third, we introduce the STRAGO model, incorporating monopolistic competition, dynamics and additive transport costs. STRAGO is applied to the analysis of effects from a kilometer tax on freight. The last paper presents a framework for studying the division, or fragmentation of production. This framework uses the standard theory of monopolistic competition, with a production chain extension, through a recursive view of markets. The optimal level of fragmentation in such industries is studied. / QC 20100811 spatial computable general equilibrium monopolistic competition dynamic organization new economic geography fragmentation production chains vertical horizontal regional economics trade.
