There is a striking variation in the prevalence of the human immunodeficiency virus (HIV) among countries and regions of the world, with a distinct geographical pattern. This paper explores the link between income inequality and HIV. It presents empirical evidencea meta-study and additional...

Wage-differentials by education of men and women are examined from African household surveys to suggest private wage returns to schooling. It is commonly asserted that returns are highest at primary school levels and decrease at secondary and postsecondary levels, whereas private returns in six...

This paper studies the influence of consumption externalities in the Ramsey model. In contrast to the recent literature, a quite general specification of preferences is used and the concept of the effective intertemporal elasticity of substitution is introduced. We give conditions for the...

In an influential paper Mankiw, Romer, and Weil (1992) argue that the evidence on the international disparity in per-capita income levels and growth rates is consistent with a standard Solow model, once it has been augmented to include human capital as an accumulable factor. In a study on...

Late 19th century investors demanded compensation to invest in countries with poor institutional protection of property rights. Using the monthly stock returns of 1,808 firms located in 43 countries but traded in London between 1866 and 1907, we estimate the country-specific cost of capital. We...

In this paper, we study the long- and short-run relationship between regional public debt and economic performance for a sample of German federal states over the period of four decades (1970-2010). By choosing a sample of regional entities with comparable institutional settings, we complement...

This paper puts the Reinhart-Rogoff dataset to a formal econometric testing to see whether public debt has a negative nonlinear effect on growth if public debt exceeds 90% of GDP. Using nonlinear threshold models, we show that the negative nonlinear relationship between debt and growth is very...

We examine the contribution of human capital to economy-wide technological improvements through the two channels of innovation and imitation. We develop a theoretical model showing that skilled labor has a higher growth-enhancing effect closer to the technological frontier under the reasonable...

Although cross section relationships are often taken to indicate causation, and especially the important impact of economic growth on many social phenomena, they may, in fact, merely reflect historical experience, that is, similar leader-follower country patterns for variables that are causally...
