Are developing-world cities engines of opportunities for low-wage earners? In this study, we track a cohort of young low-income workers in Brazil for thirteen years to explore the contribution of factors such as industrial structure and skill segregation on upward income mobility. We find that...

Institutions of justice, like prisons, can be used to serve economic and other extrajudicial interests, with lasting deleterious effects. We study the effects on incarceration when prisoners are primarily used as a source of labor using evidence from British colonial Nigeria. We digitized 65...

We construct a grid that covers the key business functions of an establishment and the main technologies used in each of them. We populate this grid with data from over 20,000 establishments in 15 countries. We use this dataset to document novel "facts" about how establishments use technology,...

Economic models provide little insight into when the next big idea and its associated productivity dividend will come along. Once a general purpose technology (GPT) is identified, the economist's toolkit does provide an understanding when firms will adopt a new technology and for what purpose....

Transformative technologies like generative artificial intelligence promise to accelerate productivity growth across many sectors, but they also present new risks from potential misuse. We develop a multi-sector technology adoption model to study the optimal regulation of transformative...

This paper examines recent proposals and research suggesting that AI adoption should be delayed until its potential harms are properly understood. It is shown that conclusions regarding the social optimality of delayed AI adoption are sensitive to assumptions regarding the process by which...

Variation in technology adoption is a key driver of differences in productivity. Previous studies sought to explain variations in technology adoption by heterogeneity in profitability, costs of adoption, or other factors. Less is known about how adoption is affected by bias in the perceived...

Generative Artificial Intelligence (AI) is a potentially important new technology, but its impact on the economy depends on the speed and intensity of adoption. This paper reports results from the first nationally representative U.S. survey of generative AI adoption at work and at home. In...

We study how financial development affects economic development and wage inequality. We use a large expansion of government-owned banks into Brazilian cities with low bank branch coverage and combine it with data on the universe of employees from 2000-2014. We find that higher financial...

We study a fundamental institution in many societies: the structure of property rights over land. Across societies, communal land rights have been more common than private land rights. We test the hypothesis that longer fallow requirements - the time needed to leave land uncultivated to restore...
