This paper attempts to investigate the extent to which trade openness has had an impact on the levels of income and rates of growth in a sample of 115 developing countries for the period 1970–2009. Additionally, to assess whether there is an income level threshold for a country to benefit from international trade, the sample is broken down into three mutually exclusive groups of countries: low-income, lower middle-income, and upper middle-income countries. The main novelty of the paper lies on the use, on the one hand, of a new and better trade openness measure and, on the other hand, of non-stationary heterogeneous panel cointegration techniques to cope with the problem of cross-sectional dependence. The results show a positive bi-directional relationship between trade openness and income level in the long run, thus suggesting that trade openness is both a cause and a consequence of the level of income. The results for the short run, that is, the link between openness growth and economic growth, go in the same direction.

The aim of this paper is to study the determinants of FDI in the 260 EU NUTS2 regions between 2000 and 2006. After reviewing the relevant literature and the major traits of the FDI regional distribution in the EU, we analyse its drivers. First, we specify the model and perform a factor analysis to reduce the vast number of potential determinants to a manageable size. Afterwards, we estimate a reduced version of the model with the extracted factors as independent variables. We find that economic potential, labour market characteristics, technological progress and competitiveness exert a significant impact on FDI location patterns; in contrast, market size and labour regulation do not seem to play any noteworthy role. Finally, we perform some robustness tests to make sure the results are not sensitive to outliers, spatial dependence, size of regions, endogeneity and the consideration of just the top 50 FDI recipient regions
