We analyze the role of risk-sharing institutions in transitions to modern economies. Transitions requires individual-level risk-taking in pursuing productivity-enhancing activities including using and developing new knowledge. Individual-level, idiosyncratic risk implies that distinct...

This paper examines the economic origins of the Islamic revival that took place in Egypt in the 1970-80s, and in Muslim societies more generally. We provide the first systematic evidence of a decline in social mobility among educated youth in Egypt. Developing a behavioral model of religion, we...

Although cross section relationships are often taken to indicate causation, and especially the important impact of economic growth on many social phenomena, they may, in fact, merely reflect historical experience, that is, similar leader-follower country patterns for variables that are causally...

We propose a unified growth theory to investigate the mechanics generating the economic and demographic transition, and the role of mortality differences for comparative development. The framework can replicate the quantitative patterns in historical time series data and in contemporaneous...

We investigate the effects of interregional labor market integration in a two-sector, overlapping-generations model with land-intensive production in the non-tradable goods sector (housing). To capture the response to migration on housing supply, capital formation is endogenous, assuming that...

The United States provides a unique laboratory for understanding how the cultural, institutional, and human capital endowments of immigrant groups shape economic outcomes. In this paper, we use census micro-sample information to reconstruct the country-of-ancestry distribution for US counties...

We study the long-term determinants of the high rates of HIV infection in sub-Saharan Africa, particularly among women, with a focus on family structure and sexual behavior as shaped by the demographic shock following the transatlantic slave trade. First we show that, in clusters where polygyny...

We model an infinitely repeated Tullock contest, over the sharing of some given resource, between two ethnic groups. The resource is allocated by a composite state institution according to relative ethnic control; hence the ethnic groups contest the extent of institutional ethnic bias. The...

This paper studies relationships between social networks, health and subjective well-being (SWB) using nationally representative data of the Chinese Population - the Chinese Family Panel Studies (CFPS). Our data contain SWB indicators in two widely used variants - happiness and...
