This study estimates the dose-response relationship between Body Mass Index (BMI) and crash risk in commercial motor vehicle operators. Intake data was collected on 744 new truck drivers who were training for their commercial driver's licenses at a school operated by the cooperating trucking...

The presence of a heavy truck on the road can impose an externality if accidents occur that would not have otherwise. We find each additional truck on the road increases the risk of a truck accident – but also, at an even higher rate, the risk of a car-on-car collision. Our estimates imply two...

In the United States, about 28 lives are lost daily in motor vehicle accidents that involve an alcohol-impaired driver. While most states have enacted traffic-safety laws to address this phenomenon, little consensus exists on the causal impact of these laws in reducing drunk-driving fatalities....

In the past 25 years, several states and the District of Columbia have implemented statewide marijuana laws. By employing difference-in-differences model and using the data from the Fatality Analysis Reporting System (FARS), this paper focuses on the effects of policy changes that legalize the...

Throughout the years spanned by the US Vital Statistics Linked Birth and Infant Death Data (1983-2002), birth weights are measured most precisely for children of white and highly educated mothers. As a result, less healthy children, who are more likely to be of low socioeconomic status, are...

There is a substantial correlation between household debt and bodyweight. Theory suggests that a causal relationship between debt and bodyweight could run in either direction or both could be caused by unobserved common factors. We use OLS and Propensity Score Matching to ascertain if household...

It is well known that a substantial part of income and education is passed on from parents to children, generating substantial persistence in socio-economic status across generations. In this paper, we examine whether another form of human capital, health, is also largely transmitted from...

This study exploits plausibly exogenous variation from the youngest sibling's school eligibility to estimate the effects of parental work on the weight outcomes of older children in the household. Data come from the 1979 cohort of the National Longitudinal Survey of Youth linked to the Child and...

The US trucking industry trade press often portrays the US labor market for truck drivers as not working, citing persistent driver shortages and high levels of firm‐level turnover, and predicting significant resulting constraints on the supply of motor freight services. We investigate the...
