Doran, Kirk; Gelber, Alexander; Isen, Adam - National Bureau of Economic Research (NBER) - 2014
We study the effect of a firm winning an additional H-1B visa on the firm’s outcomes, by comparing winning and losing firms in the Fiscal Year 2006 and 2007 H-1B visa lotteries. We match administrative data on the participants in these lotteries to the universe of approved U.S. patents, and to...

Exporting and Plant-Level Efficiency Gains: It's in the Measure
Marin, Alvaro Garcia; Voigtländer, Nico - National Bureau of Economic Research (NBER) - 2013
While there is strong evidence for productivity-driven selection into exporting, previous research has mostly failed to identify export-related efficiency gains within plants. This non-result is derived from revenue productivity (TFPR), thus also reflecting pricing decisions of exporters. Using...

Schmalensee, Richard - National Bureau of Economic Research (NBER) - 2013
Government subsidies have driven rapid growth in U.S. wind and solar generation. Using data on hourly outputs and prices for 25 wind and nine solar generating plants, some results of those subsidies are studied in detail: the value of these plants' outputs, the variability of output at plant and...

Hoping to Win, Expected to Lose: Theory and Lessons on Micro Enterprise Development
Karlan, Dean; Udry, Christopher; Knight, Ryan - National Bureau of Economic Research (NBER) - 2012
Many basic economic theories with perfectly functioning markets do not predict the existence of the vast number of microenterprises readily observed across the world. We put forward a model that illuminates why financial and managerial capital constraints may impede experimentation, and thus...
