A fundamental question in social sciences relates to the effect of wealth inequality on economic growth. Yet, in tackling the question, researchers have had to use income as a proxy for wealth. We derive a global measure of wealth inequality from Forbes magazine's listing of billionaires and...

The paper investigates the effects of nursing overtime on nosocomial infections and medical accidents in a neonatal intensive care unit (NICU). The literature lacks clear evidence on this issue and we conjecture that this may be due to empirical and methodological factors. We thus focus on a...

Will an aging population lower economic growth? Economists are generally concerned that the increase in life expectancy could lower economic growth, however, theory does not make a prediction. As life expectancy increases, so should household savings, which results in more physical capital per...

This paper provides a long-term view by studying the effect of the underground or shadow economy on economic growth in the Unites States over the period 1870 to 2014. Shadow activities might spur or retard economic growth depending on their interactions with the formal sector and impacts on the...

This paper develops an adaptive learning model under uncertainty that examines evolution of capital account polices over time and across developing regions. In the framework, countries' past experiences and IMF programs influence policymakers' beliefs about the impact of capital account...

This survey reviews the recent research on trust, institutions and growth. It discusses the various measures of trust and documents the substantial heterogeneity of trust across space and time. The conceptual mechanisms and the methods employed to identify the causal impact of trust on economic...

This essay investigates the determinants of the growth performance of Africa. I start by illustrating a broader research agenda which accounts not only for basic economic and demographic factors, but also for the role of history and institutional development. After reporting results from...

This paper investigates the empirical role of violent conflicts for the causal effect of democracy on economic growth. Exploiting within-country variation to identify the effect of democratization during the 'Third Wave', we find evidence that the effect of democratization is weaker than...

There exists a persistent disagreement in the literature over the effect of business cycles on economic growth. This paper offers a solution to this disagreement, suggesting that volatility carries a positive direct effect, but also a negative indirect effect, operating through the insurance...

This paper suggests that the weak empirical effect of human capital on growth in existing cross-country studies is partly the result of an inappropriate specification that does not account for the different channels through which human capital affects growth. A systematic replication of earlier...
