摘要：Electronic medical records (EMRs) facilitate fast and accurate access to patient records, which could improve diagnosis and patient monitoring. Using a 12-year county-level panel, we find that a 10 percent increase in births that occur in hospitals with EMRs reduces neonatal mortality by 16 deaths per 100,000 live births. This is driven by a reduction of deaths from conditions requiring careful monitoring. We also find a strong decrease in mortality when we instrument for EMR adoption using va...

摘要：A direct consequence of restricting the price of a good for which secondary markets do not exist is that, in the presence of excess demand, the good will not be allocated to the buyers who value it the most. We demonstrate the empirical importance of this allocative cost for the U. S. residential market for natural gas, which was subject to price ceilings during 1954-89. Using a household-level, discrete-continuous model of natural gas demand, we estimate that the allocative cost in this marke...

摘要：I develop a model of costly capital reallocation to understand how leasing reduces trading frictions. Leased assets trade more frequently and produce more output than owned assets because (1) high-volatility firms are more likely to lease than low-volatility firms and (2) firms shed leased asssets faster than owned assets amid productivity shocks because of lower transaction costs. Commercial aircraft data show that leased aircraft have holding durations 38 percent shorter and fly 6.5 percent ...

摘要：We study a model in which voters choose between two candidates on the basis of both ideology and competence. While the ideology of the candidates is commonly known, voters are imperfectly informed about competence. Voter preferences, however, are such that ideology alone determines voting. When voting is compulsory, the candidate of the majority ideology prevails, and this may not be optimal from a social perspective. However, when voting is voluntary and costly, we show that turnout adjusts e...
