Most papers that employ Differences-in-Differences estimation (DD) use many years of data and focus on serially correlated outcomes but ignore that the resulting standard errors are inconsistent. To illustrate the severity of this issue, we randomly generate placebo laws in state-level data on female wages from the Current Population Survey. For each law,(More)
The evaluation of numerous school reforms requires an understanding of the value of better schools. Given the difficulty of calculating the relationship between school quality and student outcomes, I turn to another method and use house prices to infer the value parents place on school quality. I look within school districts at houses located on attendance(More)
We study race in the labor market by sending fictitious resumes to help-wanted ads in Boston and Chicago newspapers. To manipulate perceived race, resumes are randomly assigned African-Americanor White-sounding names. White names receive 50 percent more callbacks for interviews. Callbacks are also more responsive to resume quality for White names than for(More)
Financial markets appear to improve the allocation of capital. Across 65 countries, those with developed "nancial sectors increase investment more in their growing industries, and decrease investment more in their declining industries, than those with undeveloped "nancial sectors. The e$ciency of capital allocation is negatively correlated with the extent(More)
Much of our understanding of corporations builds on the idea that managers, when they are not closely monitored, will pursue goals that are not in shareholders’ interests. But what goals would managers pursue? This paper uses variation in corporate governance generated by state adoption of antitakeover laws to empirically map out managerial preferences. We(More)
Previous authors have documented a dramatic decline in food expenditures at the time of retirement. We show that this is matched by an equally dramatic rise in time spent shopping for and preparing meals. Using a novel data set that collects detailed food diaries for a large cross section of U.S. households, we show that neither the quality nor the quantity(More)

We present evidence on whether workers have social preferences by comparing workers’ productivity under relative incentives, where individual effort imposes a negative externality on others, to their productivity under piece rates, where it does not. We find that the productivity of the average worker is at least 50 percent higher under piece rates than(More)
Interpersonal preferences – preferences that depend on the characteristics of others – are typically hard to infer from observable individual behavior. As an alternative approach, this paper uses survey data to investigate interpersonal preferences. The General Social Survey contains self-reported preferences for welfare spending, which I validate with(More)
Does import competition alter the extent to which employers, after negotiating workers’ wages upon hire, subsequently shield those wages from external labor-market conditions? If increased competition induces a switch away from these wage implicit agreements, then (1) the sensitivity of workers’ wages to the current unemployment rate should increase as(More)
