We bridge the gap between the standard theory of growth and the mostly static theory of corruption. Some public investment can be diverted from its purpose by corrupt individuals. Voters determine the level of public investment subject to an incentive constraint equalizing the returns from...

Corruption is thought to prevent poor countries from catching-up. We analyze one channel through which corruption hampers growth: public investment can be distorted in favor of specific types of spending for which rent-seeking is easier and better concealed. To study this distortion, we propose...

In this paper we argue that if the cross-country heterogeneity in productivity is more important than the heterogeneity in government quality, it can be optimal to give more foreign aid to more corrupt countries. We build a multi-country model of optimal aid in which we disentangle the...

We develop a theory of marriage and fertility, distinguishing the choice to have children from the choice of the number of children. The deep parameters of the model are identified from the 1990 US Census. We measure voluntary and involuntary childlessness, and explain why (1) single women are...

Consider an economy populated by males and females, both rich and poor. The society has to choose one of the following marriage institutions: polygyny, strict monogamy, and serial monogamy (divorce and remarriage). After having identified the conditions under which each of these equilibria...

We built a unique dataset of 300,000 famous people born between Hammurabi's epoch and 1879, Einstein's birth year. It includes, among other variables, the vital dates, occupations, and locations of celebrities from the Index Bio-bibliographicus Notorum Hominum (IBN), a very comprehensive...

We propose a new theory of the demographic transition based on the evidence that body development during childhood is an important predictor of adult life expectancy. Fertility, childhood development, longevity, education and income growth all result from individual decisions. Parents face a...

We assess the merits of different education systems in a framework that accounts for the joint decision problem of parents regarding fertility and education. Specifically, we compare the implications of a public and a private schooling regime for economic growth and inequality. We find that...

We propose amodelwith some of themain demographic, economic and institutional factors usually considered to matter in the transition to modern growth. We apply our theory to England over the period 1530-1860. We use the model to measure the impact of mortality, population density and...

We explore the consequences of liberalized credit markets for growth and inequality in a lifecycle economy with physical and human capital accumulation, populated by households of different abilities, and calibrated to match the longrun economic performance of a panel of emerging countries....
