In this paper we analyse the role of the traditional determinants of economic growth in the African countries in the period between 1950 and 2012. Due to the specificity and the single nature of each one of these countries, methods that take into account observed and unobserved heterogeneity are used. Results highlight the relevance of the growth rate of the capital stock to growth in the short-run, which is significant in all regressions. The growth rate of the government to GDP ratio is also important in all but one of the regressions in which it appears, and its growth is harmful for the growth of GDP per capita in the short-run. The variables related to public debt do not present any relationship with economic growth. Human capital has a positive relationship with economic growth in regressions that do not include public debt. The growth rate of real GDP per capita also depends (negatively) on its past value, i.e., the lower the real GDP per capita the higher will be its growth rate.

解释非洲国家的增长-什么问题？

在本文中，我们分析了非洲国家在1950年至2012年期间传统的经济增长决定因素的作用。由于每个国家的特殊性和单一性，考虑到观察到的和未观察到的异质性的方法被使用。结果强调了短期内资本存量增长率与增长的相关性，这在所有回归分析中都非常重要。政府增长率对GDP的比率也很重要，除了其中一种回归，它的出现对短期内人均GDP的增长都是有害的。与公共债务有关的变量与经济增长没有任何关系。在不包括公共债务的回归中，人力资本与经济增长具有正相关关系。
