Over the last few decades, economists and psychologists have quietly documented the many ways in which a person's IQ matters. But, research suggests that a nation's IQ matters so much more. As Garett Jones argues in Hive Mind, modest differences in national IQ can explain most cross-country...

Do national differences in cognitive skills (CS) predict a nation’s likelihood of generating high-quality entrepreneurs who create and expand high-value businesses? We answer this question by estimating cross-country regressions that use the Acs and Szerb Global Entrepreneurship Development...

Cognitive skills are robustly associated with good national economic performance. How much of this is due to high-skill countries doing a better job of absorbing total factor productivity from the world's technology leader? Following Benhabib and Spiegel (Handbook of Economic Growth, 2005), who...

Are more intelligent groups better at cooperating? A meta-study of repeated prisoner's dilemma experiments run at numerous universities suggests that students cooperate 5-8% more often for every 100-point increase in the school's average SAT score. This result survives a variety of robustness...

Human capital plays an important role in the theory of economic growth, but it has been difficult to measure this abstract concept. We survey the psychological literature on cross-cultural IQ tests and conclude that intelligence tests provide one useful measure of human capital. Using a new...

Several leading candidate countries will eventually enter the European Monetary Union (EMU). A key question is what exchange rate management policy should be pursued after joining the European Union (EU). This paper focuses on the impact of Euro-area monetary policy on Hungary. We find that...

When money is added to a dynamic IS model, evidence from six countries indicates that money growth usually helps predict the GDP gap and that the predictive power of a short-term real interest is much weaker than previous work suggests. Thus, for dynamic IS models such as that used by Rudebusch,...

Differences in worker skill cause modest differences in wages within a country, but are associated with massive differences in productivity across countries (Hanushek and Kimko, 2000). I build upon Kremer's (1993) O-ring theory of production to explain this stylized fact. I posit that there are...
