The Market for Tractors in the EU: Price Differences and Convergence. Factor Markets Working Documents No. 35, February 2013

This study evaluates the degree of segmentation of the market for agricultural machinery and equipment in the EU. We focus on agricultural tractors, the most common and biggest investment in machinery and equipment in the agricultural sector. By using country price data for individual tractor models, we test the law of one price, i.e. the existence of a common price for tractors across EU member states. We find that significant price differences exist, yet unlike most other studies we find that large price deviations are penalised within a short time. The study also shows that transport costs are an important source of price differences, as domestic production leads to lower prices on the domestic market and as price convergence is negatively correlated with distance. Finally, price differences should not solely be understood from a geographical perspective, as evidence supports the idea that farmers’ buying power is significant in explaining price differences within countries.

EMU Convergence: Reason for Encouragement. ACES Working Paper (Report) No. 6, 2007

The purpose of this paper is to investigate whether convergence is actually occurring within Europe, which groups of countries are converging, and the macroeconomic indicators for which such convergence is apparent. Free trade and a single currency should lead to convergence in rates of inflation, but perhaps not in unemployment rates or in GDP growth. These latter aspects of economic performance are politically important, because the voters become decidedly displeased if unemployment is high and growth slow, as has been the case in France, Germany, and Italy during recent years.

From Convergence to Diffusion: The EU's influence on national tax systems. ACES Cases No. 2011.2

In this article I investigate to what extent European Integration stimulates policy convergence and diffusion of various forms of tax policy. Using a mixed-methods design, I find that several causal mechanisms contribute to an EU-wide diffusion of tax policies: imposition, competition, harmonization and learning/communication. I show that these mechanisms have different effects on different forms of taxation. Even if the ultimate outcome of this influence only in few cases leads to unconditional convergence, the EU has markedly accelerated policy diffusion among its member states.
