Do openness to trade and higher levels of human capital promote faster productivity growth? That they do is a key implication of several versions of endogenous growth theory. To answer the question we use panel data on 93 countries spanning the 1970-2000 period. Controlling for fixed effects as...

Do openness to trade and higher levels of human capital growth promote faster growth? To answer that question we use a panel of countries to investigate the role of human capital and two measures of openness in determining both the level of income and its growth rate. We argue that focusing on...

This paper studies the distributional impact of commodity price shocks over the both the short and very long run. Using a GARCH model, we find that Australia experienced more volatility than many commodity exporting developing countries over the periods 1865-1940 and 1960-2007. A single equation...

This paper introduces new data on climatic conditions to empirical tests of growth theories. We find that, since 1960, temperate countries have converged towards high levels of income while tropical nations have converged towards various income levels associated with economic scale and the...

Why do so many African governments consistently impose high tax rates and make little investment in productive public goods when alternative policies could yield greater tax revenues and higher national income? We posit and test an intertemporal political economy model in which the government...

Oil prices experienced in early life predict differential adult outcomes across Nigerian ethnic groups. Our difference-in-difference approach compares members of southern ethnicities to other Nigerians from the same birth cohort. Greater prices in a southern individual’s birth year predict...

We study the origins of adult mental health using early life income fluctuations. Combining a time series of real producer prices of cocoa with a nationally representative household survey in Ghana, we show that a one standard deviation rise in the cocoa price in early life decreases the...

What is the relationship between entrepreneurial saving practices and reinvestment? We develop a model of entrepreneurial finance and show that entrepreneurial reinvestment decisions depend on the efficiency of saving practices. Utilizing a novel micro & small enterprise survey from Tanzania we...

We report on a randomized field experiment using price incentives to address both economic and gender inequality in land tenure formalization. During the 1990s and 2000s, nearly two dozen African countries proposed de jure land reforms extending access to formal, freehold land tenure to millions...

Using data from a randomized control trial in Sri Lanka, this paper explores whether cash and in-kind grants helped microenterprises approach the productivity level of SMEs. The paper first estimates production functions and subsequently treatment effects on TFP levels. Most significantly, more...
