In the presence of markup differences, externalities and other social considerations, the equilibrium direction of innovation can be systematically distorted. This paper builds a simple model of endogenous technology, which generalizes existing comparative static results and characterizes...

We estimate the causal effect of the diffusion of solar photovoltaic (PV) systems on the fraction of Green Party votes in federal and state elections in Baden-Württemberg, Germany. Our estimates are based on instruments that induce exogenous variation in roof appropriateness to PV installation....

Using a detailed dataset of hospitals' purchase orders, we find that information on purchasing by peer hospitals leads to reductions in the prices hospitals negotiate for supplies. Identification is based on staggered access to information across hospitals over time. Within coronary stents,...

This paper examines the importance of buyer-supplier relationships, geography and the structure of the production network in firm performance. We develop a simple model where firms can outsource tasks and search for suppliers in different locations. Low search and outsourcing costs lead firms to...

This paper uses a database covering the universe of French firms for the period 1990--2007 to provide a forensic account of the role of individual firms in generating aggregate fluctuations. We set up a simple multi-sector model of heterogeneous firms selling to multiple markets to motivate a...

Recent policy debates have focused on whether restricting for-profit institutions' access to federal student financial aid could reduce student loan defaults without restricting prospective students' access to higher education. We examine the effects of similar restrictions imposed on over 1,200...

We evaluate the Car Allowance Rebate System (CARS) by comparing the vehicle purchases and disposals of households with eligible "clunkers" to those of households with similar, but ineligible, vehicles. We find that CARS caused roughly 500,000 purchases during the program period and that the...
