A large research program in economics has established a persuasive link between institutions and economic development. But what does this imply for development policymaking? Can a political leader or aid agency seeking to promote development readily change institutions? This article starts off...

Social cohesion - that is, the inclusiveness of a country's communities - is essential for generating the trust needed to implement reforms. Citizens have to trust that the short-term losses that inevitably arise from reform, will be more than offset by long-term gains. However, in countries...

Well-meaning national and international bureaucracies dispense foreign aid under conditions in which bureaucracy fails. The environment that created aid bureaucracies led those organizations to (a) define their output as money disbursed rather than service delivered, (b) produce many low-return...

The classic narrative of economic development -- poor countries are caught in poverty traps, out of which they need a Big Push involving increased aid and investment, leading to a takeoff in per capita income -- has been very influential in development economics since the 1950s. This was the...

Using a newly assembled dataset spanning from 1820 to 1998, we study the relationship between the occurrence and cruelty of episodes of mass killing and the levels of development and democracy across countries and over time. We find that massacres are more likely at intermediate levels of income...

Does economic development depend on geographic endowments like temperate instead of tropical location, the ecological conditions shaping diseases, or an environment good for grains or certain cash crops? Or do these endowments of tropics, germs, and crops affect economic development only through...

Modern political economy stresses"society's polarization"as a determinant of development outcomes. Among the most common dorms of social conflict are class polarization, and ethnic polarization. A middle class consensus is defined as a high share of income for the middle class and a low degree...

The classic narrative of economic development—poor countries are caught in poverty traps, out of which they need a Big Push involving increased investment, leading to a takeoff in per capita income—has been very influential in foreign aid debates since the 1950s. This was the original...

The Schelling model of a "tipping point" in racial segregation, in which whites flee a neighborhood once a threshold of nonwhites is reached, is a canonical model of strategic interdependence. The idea of "tipping" explaining segregation is widely accepted in the academic literature and popular...

We assemble a dataset on technology adoption in 1000 BC, 0 AD, and 1500 AD for the predecessors to today's nation states. We find that this very old history of technology adoption is surprisingly significant for today's national development outcomes. Our strong and robust results are for 1500 AD...
