There is still hardly any empirical evidence on how divergent broadband technologies, and, by extension, bandwidth levels, influence GDP growth, or on the extent of spatial externalities at a regional level. Our study aims to assess the economic benefits of high-speed broadband networks within...

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...

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...

Firms' investment decisions involve analyzing prices, products, technologies, productive capacity and the availability of credit. These and other factors were greatly impacted by the 2009 post-crisis economic environment in Brazil. We measure the after crisis impacts of subsidized credit on the...

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...

Germany intends to reach climate neutrality in 2045, tripling the speed of emission reductions that was achieved between 1990 and 2019. Soaring energy prices and the need to replace Russian energy imports have amplified the urgency to act. Various policy adjustments are needed to ensure...

Independent and high-quality evaluations of government policies are an important input for designing evidence-based policy. Lack of incentives and institutions to write such evaluations, on the other hand, carry the risk of turning the system into a costly beauty contest. We study one of the...

Virtually all theories of economic growth predict a positive relationship between population size and productivity. In this paper I study a particular historical episode to provide direct evidence for the empirical relevance of such scale effects. In the aftermath of the Second World War about...

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...
