Empirical results on the links between trade openness and economic growth often suggest that, in the long run, more outward‐oriented countries register better economic growth. However, a similar level of trade openness can hide different types of trade structures. The aim of this paper was to enrich the way of measuring trade openness taking into account two different dimensions of countries’ integration in world trade: export quality and export variety. Based on the estimation of an endogenous growth model on a panel of 169 countries between 1988 and 2014 using a generalised method of moments estimator, our results confirm that countries exporting higher quality products and new varieties grow more rapidly. More importantly, we find a non‐linear pattern between the export ratio and the quality of the export basket, suggesting that openness to trade may impact growth negatively for countries which are specialised in low‐quality products. A non‐linear relationship between export variety, the export ratio and growth is also found, suggesting that countries increasing their exports will grow more rapidly after reaching a certain degree of the extensive margin of exports.

The aim of this paper is to examine the effects of foreign direct investments (FDI) on food security for 55 developing countries in a panel framework over the period 1995-2009. There are various measures of food security that can be used. Our first contribution is to build a composite indicator that synthesizes the food indicators used by the Food and AgricultureOrganization to measure the food availability and food utilization. Second, our empirical study is based on a model composed of a food security equation and an agricultural production equation. Our results show that sectoral FDI have different effects on food security. FDI in the agriculture sector improves food security and FDI in the secondary and tertiary sector increases the food insecurity. We found a significant FDI's spillover through the agricultural production to food security. While the effect is positive with FDI in secondary sector, it is negative for FDI in the tertiary sector.

EU enlargement and the recent sovereign‐debt crisis of Euro zone countries have revived the debate around the (European Monetary Union) EMU. In this article we ask how informal barriers to agricultural and food trade have changed since the introduction of the common European currency, and whether this evolution can be attributed to monetary integration. We focus on the foreign trade of the 11 EMU founder countries over a nine‐year period covering the creation of the EMU and find a diminishing marginal trade impact of both information and institutional barriers. We find a lower level of trade barriers, but cannot attribute this outcome to the introduction to the Euro.

This article focuses on the comparison of sacrifice ratios as an indicator for structural dispersion within the euro area over the period 1972-2003. Estimates of the sacrifice ratio, defined as the cumulative output cost arising from permanent inflation reduction, are obtained using structural VAR models. Results from sub-period analysis as well as 10-year-period rolling estimates lead to two main conclusions. First, empirical evidence displays a recent increase in the average sacrifice ratio, which can be linked to the simultaneous decrease in the average inflation rate: this negative relationship between the initial level of inflation and the cost of disinflation can be seen as a justification for the choice of an inflation objective close to 2% for the European Central Bank (ECB) rather than a target of perfect price stability, potentially very damaging. Second, we cannot provide evidence of any reduction in European sacrifice ratio dispersion, which would suggest that the nominal convergence triggered by the Maastricht Treaty did not involve a true reduction of structural differences. It is likely to be a problem in the stance of a single monetary policy, because structural differences imply asymmetric responses of real national economies to the same monetary impulse.sacrifice ratio, monetary policy, convergence, Economic and Monetary Union (EMU),
