A pervasive phenomenon in developing countries is that self-prescribed medications are purchased from drug vendors without professional supervision. In this article we develop a model of self-medicating behavior of a utility-maximizing consumer who balances the benefits and risks of...

This paper estimates treatment effects of managed care plans on the utilization of health care services using data from two contemporaneous, nationally representative household surveys from the USA. The paper exploits recent advances in simulation-based econometrics to take the endogeneity of...

SUMMARY In this paper, we estimate a copula‐based bivariate dynamic hurdle model of prescription drug and nondrug expenditures to test the cost‐offset hypothesis, which posits that increased expenditures on prescription drugs are offset by reductions in other nondrug expenditures. We apply...

This article analyzes the effect of gatekeeper and network restrictions on use of health-care services using simulation-based estimation methods. Data from the Community Tracking Survey (1996-1997) show significant evidence of selection into plans with gatekeeper and|or network restrictions....

This paper takes a finite mixture approach to model heterogeneity in incentive and selection effects of drug coverage on total drug expenditure among the Medicare elderly US population. Evidence is found that the positive drug expenditures of the elderly population can be decomposed into two...

This paper explains and empirically assesses the channels through which population aging may impact on income-related health inequality. Long panel data of Swedish individuals is used to estimate the observed trend in income-related health inequality, measured by the concentration index (CI). A...
