We present a model of wage contract violation that implies a possibility of multiple equilibria in the level of arrears. Positive feedback arises because each employer's arrears affect the costs of late payment faced by other employers operating in the same labor market, resulting in a network...

Field evidence suggests that people belonging to the same group often behave similarly, i.e., behaviour exhibits social interaction effects. We conduct an experiment that avoids the identification problem present in the field. Our novel design feature is that each subject simultaneously is a...

We present a model of neighborhood effects in wage payment delays. Positive feedback arises because each employer’s arrears affect the late payment costs faced by other firms in the same local labor market, resulting in a strategic complementarity in the practice. The model is estimated on...

We develop a model where the decision to commit a crime in a neighboring area is a positive function of the percentage of same-race individuals residing in that area since they can provide crucial information on crime possibilities. The model then predicts a positive spatial correlation in crime...

Numerous studies have evaluated the effect of nutrition early in life on health much later in life by comparing individuals born during a famine to others. Nutritional intake is typically unobserved and endogenous, whereas famines arguably provide exogenous variation in the provision of...

In response to the dramatic rise in childhood obesity, the Centers for Disease Control (CDC) and other organizations have advocated increasing the time that elementary school children spend in physical education (PE) classes. However, little is known about the effect of PE on child weight. This...

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...

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...

This paper develops a conceptual framework that can explain why economic development goes along with increases in body weight and obesity rates. We first introduce the concept of novelty consumption, which refers to an increase in food availability due to trade or innovation. Then we study how...

Despite the urgent public health implications, relatively little is yet known about the effect of peers on adolescent weight gain. We describe trends and features of adolescent BMI in a nationally representative dataset and document correlations in weight gain among peers. We find strong...
