In this thesis it is analyzed if promoting product market competition can help to to fight unemployment in Europe. We have used a general equilibrium model in order to study how reducing mark-ups and increasing productivity in one sector affect aggregate unemployment for an exogenously given...

In this paper we develop a spatial Cournot trade model with two unequally sized countries, using the geographical interpretation of the Hotelling line. We analyze the trade and welfare effects of international trade between these two countries. The welfare analysis indicates that in this...

One of the fundamental normative questions within international trade theory is whether free trade is better than autarky and, if so, in what sense and to what extent. Surprisingly, the literature contains just a few formal models constructed under discrete time and investigating the...

General financial models have become workhorse models in the fields of macroeconomics and finance. These models have been developed and extensively studied by general equilibrium theorists. What makes them so applicable for macroeconomics and finance is the well accepted fact that models with a...

We quantify the effect of financial leverage on stock return volatility in a dynamic general equilibrium economy with debt and equity claims. The effect of financial leverage is studied both at a market and a firm level where the firm is exposed to both idiosyncratic and market risk. In a...

This paper examines the impact of imposing different separability assumptions in the specifications of the standard hierarchical KLEM production function in a computable general equilibrium (CGE) model. The appropriate means of introducing energy to sectoral production functions in CGE models...
