Mass adult male circumcision campaigns for HIV prevention are underway across much of Sub-Saharan Africa. However, concern remains about risk compensation associated with the reduction in the probability of HIV transmission per risky act. This paper examines the be- havioral response to male...

This research argues that variations in the interplay between cultural assimilation and cultural diffusion have played a significant role in giving rise to differential patterns of economic development across the globe. Societies that were geographically less vulnerable to cultural diffusion...

This paper is an exploratory analysis of the role that banks play in supporting what Jevons called the mechanism of exchange. It considers a model economy in which exchange activities are facilitated and coordinated by a self-organizing network of entrepreneurial trading firms. Collectively,...

We assess quantitatively the effect of exogenous reductions in fertility on output per capita. Our simulation model allows for effects that run through schooling, the size and age structure of the population, capital accumulation, parental time input into child-rearing, and crowding of fixed...

A common critique of globalization is that it leads to a race to the bottom. Speci?cally, it is assumed that multinationals invest in countries with lower regulatory standards and that countries competitively undercut each other's standards in order to attract foreign capital. This paper tests...

Copper mining is among the largest economic activities in Zambia, comprising close to ten percent of GDP. Between 2003 and 2008, the price of copper increased by over 400 percent. In response, copper production in Zambia grew by 70 percent and employment in copper mining increased by nearly 200...

This paper examines the effects of antiretroviral therapy (ART) on demand for HIV testing and of ART-induced testing on demand for risky sexual behavior. I provide a model of sexual behavior decision-making under uncertainty and estimate the structural parameters of the model using nationally...

This paper examines the role played by a specific identity, defined as the attachment to a hometown, in determining occupational choice and mobility. The analysis links competition between ethnic networks in the Midwest when it was first developing, and the in-group identity that emerged...

This research examines theoretically and empirically the origins of agriculture. The theory highlights the role of climatic sequences as a fundamental determinant of both technological sophistication and population density in a hunter-gatherer regime. It argues that foragers facing volatile...

This paper addresses the complex and overlooked relationship between the receipt of workers’ remittances and institutional quality in the recipient country. Using a simple model, we show how an increase in remittance inflows can lead to deterioration of institutional quality – specifically,...
