Analyse der wirtschaftlichen Situation in Polen 1987/1988 mit Fokus auf dem Außenhandel. Den wirtschaftspolitischen Rahmen bildet die sogenannte "zweite Etappe der Reform", die das marktorientierte Konzept zur Umgestaltung der Wirtschaft ergänzen und ihm zum Durchbruch verhelfen soll.

This paper introduces the computable partial equilibrium energy model 'Global Resource Extraction and Energy Transformation' (GREET), its structure, assumptions and the outcomes of two exemplary scenarios. GREET is characterized by a comprehensive modelling of constraints on the diffusion of...

In the two-country Melitz (2003) model, unilateral trade liberalization is often cast as a reduction of iceberg transportation costs and wages are determined by a linear outside sector. We show that welfare results reverse when wages adjust and trade frictions are revenue-generating tariffs.

There has been an extensive discussion on the applicability of Poisson Pseudo Maximum Likelihood (PPML) to trade. Here, we are going to analyse again the performance of PPML but in the light of a bimodal distribution; in addition, we also explicitly account for excess zeros. Simulations are...

National labour market institutions interact across national boundaries when product markets are global. Labour market policies can thus entail spill-overs, which suggest that there are benefits from international policy coordination. This paper studies the effects of wage subsidies in an...

The paper uses a gravity trade model to examine the impact of corruption on bilateral trade using a data set comprising OECD economies, new EU members and developing nations. Although the level of corruption of both the importing and exporting nations does hinder cross-border transactions,...

This paper uses comprehensive high-quality panel data from official statistics for exporting enterprises to investigate the micro-structure of the recent export collapse in manufacturing industries in Germany during the crisis of 2008/2009. Almost all of the decline in exports was due to...

The paper sets up a two-country asymmetric trade model with heterogeneous firms,search frictions and endogenous labor market institutions. Countries are linked by tradein goods and non-cooperatively set unemployment benefits to maximize national welfare.We show that more open and smaller...

In theoretical trade models with variable markups and collective wage bargaining, exportexposure may reduce the exporter wage premium. We test this prediction using linkedGerman employer-employee data from 1996 to 2007. To separate the rent-sharingmechanism from assortative matching, we exploit...
