abstract: 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 minimum real wage. The  bottom-line was that product market reforms will help to reduce aggregate  unemployment under most circumstances. Modeling a microfoundation of mark-ups, we have demonstrated that different  learning abilities of firms with respect to general equilibrium effects lead to  different levels of unemployment. If firms, competing a la Cournot, consider  only partial equilibrium effects when choosing quantities, the observation of  general equilibrium feedbacks will lead to repeated quantity adjustments until  a steady state is reached. We have used the above model to show that the impacts  of mergers of firms on employment are rather negative. We then have examined wage bargaining between employers and labor unions. We  have demonstrated that if agents do hardly consider general equilibrium effects,  low real wages and low unemployment results. With an intermediate view, when  partial equilibrium effects are taken into account, high real wages and  unemployment results. If all general equilibrium effects are incorporated at  once, again low real wages and low unemployment results. We thus have obtained  a hump-shaped relationship between the extend of feedback effects incorporated  by the bargaining parties and real wages or unemployment. Finally the impacts  of uneven productivity improvements on employment were shown to generally remain  positive when wages are set endogenously by wage bargaining.
