Health Plan Choice and the Utilization of Health Care Services
TLDR
After controlling for chronic illness and other observed variables, the authors find no evidence of further selectivity bias in equations for physician contacts and inpatient days.Abstract:
The effect of health-plan membership on the utilization of health-care services is of interest to both consumers and policymakers. Often estimation of that effect is difficult because data are nonexperimental and the dependent variable exhibits a high proportion of zeros. The authors propose a model of utilization that addresses both problems. After controlling for chronic illness and other observed variables, they find no evidence of further selectivity bias in equations for physician contacts and inpatient days. The authors' estimates of the effect of health-plan membership on utilization of services are similar to those from experimental data. Coauthors are Roger Feldman, Steven Cassou, and Michael Finch.

TL;DR: A structural model of health insurance and health care choices using data on single individuals from the NMES is estimated and it is found that riskier types buy more coverage and, on average, end up using more care.

Usual Source of Care in Preventive Service Use: A Regular Doctor versus a Regular Site
TL;DR: Promoting a stable physician-patient relationship can improve patients' timely receipt of clinical prevention and have a greater impact than having a regular site on discretional preventive services, such as blood pressure and cholesterol level checkups.

A Controlled Trial of the Effect of a Prepaid Group Practice on Use of Services
TL;DR: The lower rate of use that the authors observed, along with comparable reductions found in non-controlled studies by others, suggests that the style of medicine at prepaid group practices is markedly less "hospital-intensive" and, consequently, less expensive.
