Exports and Capacity Constraints: A smooth transition regression model for six euro-area countries. CEPS Working Document No. 395/May 2014

The significant gains in export market shares made in a number of vulnerable euro-area crisis countries have not been accompanied by an appropriate improvement in price competitiveness. This paper argues that, under certain conditions, firms consider export activity as a substitute for serving domestic demand. The strength of the link between domestic demand and exports is dependent on capacity constraints. Our econometric model for six euro-area countries suggests domestic demand pressure and capacity-constraint restrictions as additional variables of a properly specified export equation. As an innovation to the literature, we assess the empirical significance through the logistic and the exponential variant of the non-linear smooth transition regression model. We find that domestic demand developments are relevant for the short-run dynamics of exports in particular during more extreme stages of the business cycle. A strong substitutive relationship between domestic and foreign sales can most clearly be found for Spain, Portugal and Italy, providing evidence of the importance of sunk costs and hysteresis in international trade.

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.

A Greek tragedy in the making. EPC Commentary, 6 July 2015

One thing is clear: the Greek people have emphatically voted ‘No’, providing a boost to Prime Minister Alexis Tsipras and plunging Greece and the Eurozone even more into uncertainty. But it might, at the end of the day, prove to be a hollow victory for the Greek Prime Minister: the vote cannot compel the rest of the Eurozone to open their coffers and provide the funds Greece so desperately needs. It is certainly not a victory for democracy: it is highly questionable whether the Greek people could form an informed opinion, given the short time frame, the unclear question relying on a proposal no longer on the table, and the high level of misinformation on the potential consequences of the vote. This is no victory, neither for Greece nor the EU and its members: in the end, it increases the danger of Greece leaving the Eurozone – and potentially even an eventual exit from the EU –, which the people of Greece clearly do not want, as 75-80 per cent of citizens firmly want the country to stay in the euro.
