The methods used in economic research are analyzed on a sample of all 3,415 regular research papers published in 10 general interest journals every 5th year from 1997 to 2017. The papers are classified into three main groups by method: theory, experiments, and empirics. The theory and empirics...

The purpose of this article is to introduce the technique and main findings of meta-analysis to the reader, who is unfamiliar with the field and has the usual objections. A meta-analysis is a quantitative survey of a literature reporting estimates of the same parameter. The funnel showing the...

During the last 60 years development in Sub-Sahara Africa has had three main phases - P1, P2 and P3 - divided by kinks in 1972 and in 1994. P1 and P3 had fairly satisfactory growth, but P2 had negative growth. This cyclical growth path has to be explained by variables with a similar path. A set...

We try to identify which economic factors might be responsible for the large international differences in student performance. We present time series evidence for a number of European countries which suggests that rising educational expenditures obviously did not improve student performance....

We suggest a new way to quantify the growth effects of capital mobility. We find that for reasonable parameter values, capital mobility has a large impact on income growth.

Most empirical studies of long run growth refer to one of the two seminal contributions by Robert Solow (1956, 1957). His work shows that in order to estimate the relative roles of factor accumulation and technology in development, an a priori identification assumption is needed about the nature...

The role of human capital has so far not been well documented at the macroeconomic level. Many empirical studies lack a consistent theoretical foundation and there are measurement problems due to a very narrow concept of human capital focusing on formal education. Future empirical research...

Die konventionellen Indikatoren für Bildungsinput und ?output deuten darauf hin, dass sich die meisten Beitrittsländer in Bezug auf das Humankapital nicht bedeutend vom EUDurchschnitt unterscheiden. Die verfügbaren Messungen erfassen jedoch unter Umständen nicht den wirtschaftlich relevanten...
