Most economic analyses presume that there are limited differences in the prior beliefs of individuals, as assumption most often justified by the argument that sufficient common experiences and observations will eliminate disagreements. We investigate this claim using a simple model of Bayesian...

We propose a model of the emergence of equality before the law. A society can support “effort” (“cooperation”, “pro-social behavior”) using the “carrot” of future cooperation or the “stick” of coercive punishment. Community enforcement relies only on the carrot and involves...

We study the determinants of vertical integration in a new dataset of over 750,000 firms from 93 countries. Existing evidence suggests the presence of large cross-country differences in the organization of firms, which may be related to differences in financial development, contracting costs or...

Medical and public health innovations in the 1940s quickly resulted in significant health improvements around the world. Countries with initially higher mortality from infectious diseases experienced greater increases in life expectancy, population, and - over the following 40 years - social...

This paper evaluates the importance of property rights institutions', which protect citizens against expropriation by the government and powerful elites, and contracting institutions', which enable private contracts between citizens. We exploit exogenous variation in both types of institutions...

What is the effect of increasing life expectancy on economic growth? To answer this question, we exploit the international epidemiological transition, the wave of international health innovations and improvements that began in the 1940s. We obtain estimates of mortality by disease before the...

Is inequality harmful for economic growth? Is the underdevelopment of Latin America related to its unequal distribution of wealth? A recently emerging consensus claims not only that economic inequality has detrimental effects on economic growth in general, but also that differences in economic...

Thomas Piketty's (2014) book, Capital in the 21st Century, follows in the tradition of the great classical economists, like Marx and Ricardo, in formulating general laws of capitalism to diagnose and predict the dynamics of inequality. We argue that general economic laws are unhelpful as a guide...

A fundamental problem for economic development is that most poor countries have 'weak state' which are incapable or unwilling to provide basic public goods such as law enforcement, order, education and infrastructure. In Africa this is often attributed to the persistence of 'indirect rule' from...

We provide evidence that democracy has a significant and robust positive effect on GDP. Our empirical strategy relies on a dichotomous measure of democracy coded from several sources to reduce measurement error and controls for country fixed effects and the rich dynamics of GDP, which otherwise...
