A 2009 observational study reported that private insurance status is associated with decreased mortality risk compared to no insurance. Employing the same statistical model but with more recent data, we observe a weaker and statistically insignificant relationship. However, Medicaid coverage is...

In this paper we investigate the cyclicality of real wages. The approach we take is to search for the largest possible common cyclical component in a statistical sense. This contrasts with the existing literature which uses observable variables to proxy for a common cycle. We do so by using a...

We examine agreeability between mothers and caregivers in their assessments of children’s non-cognitive development. We extend the standard agreeability framework and carefully consider systematic directional differences between mothers and caregivers across maternal subgroups. Minority...

This paper analyzes the effect of traffic tickets on motor vehicle accidents. OLS estimates may be upward-biased because police officers tend to focus on areas where and periods when there is heavy traffic and thus higher rates of accidents. This paper exploits the dramatic increase in tickets...

This paper documents a startling difference in the grading standards between education departments and other academic departments at universities – undergraduate students in education classes receive significantly higher grades than students in all other classes. This phenomenon cannot be...

The traditional wisdom holds that the benefits of a decentralized channel structure arise from downstream competitive relationships. In contrast, Arya and Mittendorf (2007) showed that the value of decentralization can also arise from upstream interaction when the downstream firm conveys...

Barcode scanners were introduced in the 1970s as a way to reduce labor costs in stores, particularly at checkout. This paper is the first to estimate their effect on productivity. I use store-level data from the 1972, 1977, and 1982 Census of Retail Trade, matched to data on store scanner...

The price-to-rent ratio, a common yardstick for the value of housing, is difficult to estimate when rental properties are poor substitutes of owner-occupied homes. In this study we estimate price-to-rent ratios of residential properties in two major cities in China, where urban high-rises...

In early 2010, the U.S. Department of Health and Human Services released the findings from a large, experimental evaluation of the Head Start program. A common interpretation of the findings is that they show "small" effects, which has lead to, among other things, calls to improve the efficacy...

This paper introduces cointegrating mixed data sampling (CoMiDaS) regressions, generalizing nonlinear MiDaS regressions in the extant literature. Under a linear mixed-frequency data-generating process, MiDaS regressions provide a parsimoniously parameterized nonlinear alternative when the linear...
