"Model uncertainty hampers consensus on the key determinants of economic growth. Some recent cross-country, cross-sectional analyses have employed Bayesian Model Averaging to address the issue of model uncertainty. This paper extends that approach to panel data models with country-specific fixed...

"The authors develop an endogenous growth model that combines structural change with repeated product improvement. That is, the technologies in one sector of the model become not only increasingly capital-intensive, but also progressively productive over time. Application of the basic model to...

"This paper surveys the recent literature which examines the impact of business climate variables on productivity and growth in developing countries using enterprise surveys. Comparable enterprise surveys today cover some 70,000 firms in over 100 countries around the world. The literature that...

"This paper explores the linkage between income growth rates and foreign direct investment (FDI) inflows. So far the evidence is rather mixed, as no robust relationship between FDI and income growth has been established. The authors argue that countries need a sound business environment in the...

"Using a large cross-country income distribution dataset spanning close to 800 country-year observations from industrial and developing countries, the authors show that the size distribution of per capita income is well approximated empirically by a lognormal density. The null hypothesis that...

"External exposure can be measured by the sensitivity of first and second moments of economic growth to openness and foreign shocks. This paper provides an empirical evaluation of external exposure using panel data methods for a worldwide sample of countries. Controlling for domestic conditions,...

"The authors examine whether financial development boosts the growth of small firms more than large firms and hence provides information on the mechanisms through which financial development fosters aggregate economic growth. They define an industry's technological firm size as the firm size...

"Are natural resources a blessing or a curse? Bravo-Ortega and De Gregorio present a model in which natural resources have a positive effect on the level of income and a negative effect on its growth rate. The positive and permanent effect on income implies a welfare gain. There is a growth...

"The relationships among competition in the financial sector, access of firms to external financing, and associated economic growth are ambiguous in theory. Moreover, measuring competition in the financial sector can be complex. In this paper Claessens and Laeven first estimate for 16 countries...

"Loayza and Rancire study the apparent contradiction between two strands of the literature on the effects of financial intermediation on economic activity. On the one hand, the empirical growth literature finds a positive effect of financial depth as measured by, for instance, private domestic...
