We study how the trajectory of health for the near-elderly uninsured changes upon enrolling into Medicare at the age of 65. We find that Medicare increases the probability of the previously uninsured having excellent or very good health, decreases their probability of being in good health, and...

There are two broad classes of models used to address the econometric problems caused by skewness in data commonly encountered in health care applications: (1) transformation to deal with skewness (e.g., OLS on ln(y)); and (2) alternative weighting approaches based on exponential conditional...

Data on health care expenditures, length of stay, utilization of health services, consumption of unhealthy commodities, etc. are typically characterized by: (a) nonnegative outcomes; (b) nontrivial fractions of zero outcomes in the population (and sample); and (c) positively-skewed distributions...

We develop a formal model to show how integration solves task allocation problems between organizations and test the predictions of the model, using a large and rich patient-level dataset on hospital discharges to nursing homes and home health care. As predicted by the theory, we find that...

Two key attributes of a job are its wage and its duration. Much has been made of changes in the wage distribution in the 1980s, but little attention has been given to job durations since Hall (1982). We fill this void by examining the temporal evolution of job retention rates in U.S. labor...

In earlier work we examined the temporal evolution of job stability in U.S. labor markets through the 1980's, using data assembled from a sequence of Current Population Survey tenure supplements. We found little or no change in aggregate job stability in the U.S. economy. In addition, older and...

Using data from a survey of 800 managers in 12 industries, we find empirical support for the hypothesis that the cost associated with missed work varies across jobs according to the ease with which a manager can find a perfect replacement for the absent worker, the extent to which the worker...

Most existing studies of risk selection in the employer-sponsored health insurance market are case studies of a single employer or of an employer coalition in a single market. We examine risk selection in the employer-sponsored market by applying a switcher' methodology to a national, panel data...

Certificate of Need Laws (CON), state laws requiring providers to obtain licenses before adopting healthcare technology, have been controversial. The effect of CON on technology supply has not been well established. In part this is because analyses have focused on state-level supply effects,...

This paper uses Roy's model of sorting behavior to study welfare implication of current health care data production infrastructure that relies on solicitation of research subjects. We show that due to severe adverse-selection issues, directionality of bias cannot be established and welfare may...
