We estimate the long-term effect of public R&D on growth in manufacturing by analyzing new data from the Cold War era Space Race. We develop a novel empirical strategy that leverages US-Soviet rivalry in space technology to isolate windfall R&D spending. Our results demonstrate that public R&D...

Since 1980, US wage growth has been fastest in large cities. Empirically, we show that most of this urban-biased growth reflects wage growth at large Business Services firms, which are also the most intensive users of information and communications technology (ICT) capital in the US economy. We...

We develop a framework to estimate the economic value of a recent zoning reform in the city of Sao Paulo, which altered maximum permitted construction at the city-block level. Using a spatial regression discontinuity design, we find that developers file for more multi-family construction permits...

Infrastructure assets have undergone substantial privatization in recent decades. How do different types of owners target and manage these assets? And does the contract form--control rights (concession) vs. outright ownership (sale)--matter? We explore these questions in the context of global...

Amid rising global interest in state interventions, this paper examines how China's infrastructure investments--a key macroeconomic policy tool--affect firm productivity. We focus on a policy that encourages regional governments to improve market conditions for private enterprises. Our analysis...

Are the costs of discrimination mainly borne by the targeted group or by society? This paper examines both individual and aggregate costs of ethnic discrimination. Studying Germans living in the U.S. during World War I, an event that abruptly downgraded their previously high social standing, we...

Conventional wisdom suggests that small businesses are innovative engines of Schumpetarian growth. However, as small businesses, they are likely to face credit rationing in financial markets. If true then policies that promote lending to small businesses may yield substantial economy-wide...

U.S. county data for the last 20 or 30 years show that manufacturing employment has been deconcentrating. In contrast, the service sector exhibits concentration in counties with intermediate levels of employment. This paper presents a theory where local sectoral growth is driven by technological...

Previous work on transportation investments has focused on average impacts in high- and middle-income countries. We estimate average and heterogeneous effects in a poor continent, Africa, using roads and cities data spanning 50 years in 39 countries. Using changes in market access due to distant...

The participation of the United States in World War II led to a substantial mobilization of domestic resources to produce the materiel used on the battlefields of Europe and in the Pacific. We produce new estimates for the impact of war mobilization on long-run economic growth and regional...
