Using data on U.S. state and federal taxes and transfers over a quarter century, we estimate a regression model that yields the marginal effect of any shift of market income share from one quintile to another on the entire post tax, post-transfer income distribution. We identify exogenous income...

We document the diffusion of nebulized ibuprofen in Argentina as a treatment for COVID-19. As the pandemic spread, this clinically unsupported drug reached thousands of patients, even some seriously ill, despite warnings by the regulator and medical societies. Detailed daily data on deliveries...

Public service reforms often provoke political backlash. Can they also yield political benefits for the politicians who champion them? We study a Wisconsin law that weakened teachers' unions and liberalized pay, prompting mass protests. Exploiting its staggered implementation across school...

This paper estimates the local welfare impacts of road maintenance investments. We instrument road quality exploiting Indonesia's two-step budgeting process for allocating funding to local road authorities. Using comprehensive data on road quality from 1990-2007, we find that better roads help...

This paper studies how agricultural production responds to the loss of agricultural labor during the process of urbanization and structural transformation. Using household microdata from India and exogenous variation in migration opportunities induced by urban income shocks, we show that...

What are a country's policy options in the face of emerging technologies development in a global economy? To answer this question, we examine optimal dynamic policies in an open economy where technology is endogenously accumulated through R&D innovation. Our key insight is that a country has...

Policies aimed at raising agricultural productivity have been a centerpiece in the fight against global poverty. Their impacts are often measured using field or quasi-experiments that provide strong causal identification, but may be too small-scale to capture the general equilibrium (GE) effects...

Multinational enterprises (MNEs) increasingly impose "Responsible Sourcing" (RS) standards on their suppliers worldwide, including requirements on worker compensation, benefits and working conditions. Are these policies just "hot air" or do they impact exposed suppliers and their workers? What...

The close connection between US and China in scientific research and education in the 2000s produced a large group of China-born researchers who work in the US ("diaspora") and a larger group of China-born researchers who gained US-research experience and returned to do their research in China...

This paper studies technology absorption worldwide in the late nineteenth century. We construct several novel datasets to test the idea that the codification of technical knowledge in the vernacular was necessary for countries to absorb the technologies of the Industrial Revolution. We find that...
