- Evaluating the impact of foreign aid on economic growth: a cross-country studyPublication . Moreira, Sandrina BerthaultOne branch of the literature on aid effectiveness attempts to measure the contribution of foreign aid to the growth of developing countries. The micro results are clear and encouraging: foreign aid is beneficial to economic growth. However, until recently, the macro results were inconclusive: the impact of aid on growth was positive, negative, or even non-existent, in statistical terms. This contradiction is known as the “micro-macro paradox”. Certain methodological and econometric flaws inherent in the assessments being carried out up to the mid-nineties may provide an explanation for the misleading macro results. Examining a large panel data set, I have found that foreign aid has had a positive impact on economic growth. In light of these findings, I conclude that earlier-generation work is in accordance with the new and recent generation of aid effectiveness studies. Thus, less importance should be attributed to the “micro-macro paradox” as an overall appraisal of aid effectiveness. In terms of magnitude, I have also found that aid has less effect on growth in the short-run than in the long-run. I also conclude that the time lags in the aid-growth relationship should not be ignored.
- Born globals versus domestic venture: an exploratory study on opportunity framing differencesPublication . Simões, Vítor Corado; Dominguinhos, PedroInternational entrepreneurship is generating an increasing stream of research. However, this is mainly concerned with the description of strategies used by born globals and with the comparison between their behaviour and that of traditional exporters. The study of the very early stages of the entrepreneurial process as well as the contrast with purely domestic ventures has been neglected. This exploratory paper, based on case studies of two pairs of high tech firms (ICT and biotechnology), focusses on the differences of opportunity framing processes between born globals and domestic ventures. Empirical evidence shows that born globals’ entrepreneurs frame their opportunities with no geographic boundaries, show higher-levels of self-perception, master deeper and more complex knowledge and are more involved in international networks than the founders of domestic ventures.
