A structural econometric model of family valuation and choice of employer-sponsored health insurance in the United States.

This paper estimates a fully structural unitary household model of employment and health insurance decisions for dual wage-earner families with children in the United States, using data from the 1987 National Medical Expenditure Survey. Families choose hours of work and the breakdown of compensation between cash wages and health insurance benefits for each wage earner in order to maximize expected utility under uncertain need for medical care. Heterogeneous demand for the employer-sponsored health insurance is thus generated directly from variations in health status and earning potential. The paper concludes by discussing the benefits of using structural models for simulating welfare effects of insurance reform relative to the costly assumptions that must be imposed for identification.

Occupational gender segregation: index measurement and econometric modeling.

Empirical studies of gender segregation by occupation must be founded on rigorous measurement procedures. There appears to be a consensus that any index used in the analysis of time-series or international cross-section employment data must be either margin-free or decomposable to yield a margin-free component. On the other hand, Charles and Grusky (1995) advocate the use of multiplicative log models from which a margin-free odds ratio can be derived. In this paper, I contrast the construction and interpretation of the index of dissimilarity and the Karmel-MacLachlan index with the multiplicative modeling of gender segregation and the associated log index.

An econometric model for forecasting regional population growth.

"An econometric model for forecasting net migration and natural increase is proposed and then estimated using time-series data for Texas. The model is simulated five years out-of-sample and found to be quite accurate in forecasting future population growth. It outperforms simpler prediction methods, thus indicating that explicit modeling of net migration and natural increase is superior to modeling only total population."

Econometric models and the study of the economic effects of Social Security.

This article provides a relatively nontechnical discussion of previously published research on the use of econometric models in the study of the economic effects of social security. It illustrates the role of econometric model building by focusing on three major applications: forecasting, policy simulation, and hypothesis testing. A series of three macroeconomic examples serves to emphasize that the development and use of such models puts the focus of the analysis on the underlying economic structure. The first example presents a program-specific model of the Social Security system, the second a large-scale model of the U.S. economy, and the third a single-equation analysis of a specific issue.

Association between abciximab and length of stay in intensive care for patients undergoing percutaneous coronary intervention. A 2-stage econometric model in a naturalistic setting.

OBJECTIVE: To examine the effect of abciximab treatment on intensive care length of stay for patients undergoing percutaneous coronary intervention (PCI). DESIGN AND SETTING: A retrospective study conducted in a naturalistic setting. METHODS: A 2-stage econometric model was used to control for the influence of possible selection bias across categories of patients and for both observable and unobservable factors correlated with each patient's treatment selection and length of stay in intensive care. Multivariate analysis was applied to control for a wide range of factors (patient demographics, insurance provider, health conditions, admission and discharge information, and hospital characteristics) that may influence intensive care length of stay. Retrospective data were obtained from HCIA's Clinical Pathways Database. PARTICIPANTS: Patients (n = 13,364) who were hospitalised in any of 87 hospitals across the US over the period from October 1, 1995 to December 1, 1996. RESULTS: After controlling for high-risk indications and selection bias, results indicated that administration of abciximab was associated with a significantly shorter length of stay in intensive care compared with not administering a GPIIb/IIIa inhibitor (0.45 fewer days; p < or = 0.0001). In a subgroup analysis of patients having an acute myocardial infarction (n = 4793), administration of abciximab was also associated with a significantly shorter intensive care stay (0.27 fewer days; p < 0.0001). CONCLUSION: Results of this study indicate that the administration of abciximab is associated with a reduction in the length of stay in intensive care. This reduction implies potential cost offsets for patients undergoing PCI who receive abciximab.

The hospital response to Medicare's Prospective Payment System: an econometric model of Blue Cross and Blue Shield plans.

This paper presents an empirical analysis of the impact that resulted from phase-in of Medicare's Prospective Payment System (PPS) on hospital utilization and payments for the Blue Cross and Blue Shield (BCBS) plans. A pooled cross-sectional time series econometric model was specified and estimated using quarterly hospital utilization and payments of the BCBS plans over the period 1980 to 1987. The results indicate that the implementation of PPS was significantly associated with a lower rate of hospital admissions, days and deflated inpatient payments for the BCBS plan members under age 65. A 1% increase in the proportion of hospital days reimbursed under PPS resulted in a .032% decrease in BCBS plan admissions per 1,000 members, a 0.017% decline in days per 1,000 members and a 0.016% decline in deflated inpatient payment per 1,000 members. The reductions in hospital utilization resulted in lower payments by BCBS plans to participating hospitals suggesting a positive spill-over effect of PPS for private insurers. This research underscores the importance of interaction between federal health policy and the private health insurance market.

Demographic disaggregation in the construction of regional econometric models: a statistical evaluation.

"A cohort-component method is used to construct historical annual age/sex disaggregations of total population. In econometric models of six substate areas [in the United States], regressions are estimated with and without the disaggregated data for five model variables expected to be dependent on the size of particular population subgroups. Statistical tests are performed to determine significant differences in residual variance of estimation with and without the disaggregated data. Although age/sex population projections may be a desired model output per se, the results indicate that the population subgroup data generally do not improve estimation of other model variables."

Evidence of fertility regulation among rural French villagers, 1749-1789: a sequential econometric model of birth-spacing behavior (Part 2).

This is the second part of a two-part paper in which the authors examine statistical models of marital fertility regulation in rural France from 1749 to 1789. They create a case against the "natural fertility" characterization of the period by presenting "clear indications that marital fertility was being regulated in congruence with the differential valuations placed upon children, according to their gender and age. A complex pattern is found in the non-biological responses of couples' fertility to both non-familial and familial experience of infant deaths, which take the form of 'hoarding' and 'replacement effects', respectively. Evidence is present bearing upon the suspected endogeneity of infant deaths, and its relationship to the adoption of preventive methods of limiting family size." (SUMMARY IN FRE)

An econometric model of an episode of mental health care for patients with mild conditions: implications for caregiver substitution.

This article presents a model of the number of hours of mental health care, the concurrent improvement in the patient's condition, the probability the patient will receive medications, and the reasons for treatment termination. The variables related to these aspects of mental health care are analyzed separately for patients of psychiatrists, psychologists, and social workers. Estimates of the average length of treatment, the average price and income elasticities, and the average cost of treatment are obtained from the model. The major conclusions from this study are that psychiatrists do not have a benefit-cost advantage in the treatment of relatively mild conditions, and that consumer responsiveness to variations in price appear to be largely confined to the decision to seek treatment. These and other findings provide a basis for making tentative recommendations about personnel substitution and reimbursement policies in mental health.

An econometric model of internal migration and development: extensions and tests.

The author extends a previous work on migration in Italy "from 1958-1976 to 1958-1981, tests for the stability of the model and its coefficients, and uses the model for policy simulations and forecasting. The model performs as well over the extended sample period as over the original period and, even more important..., the model is found to be quite stable. This is remarkable in view of the economic turmoil that characterized the years by which the original sample period was extended."

Economic reform and migration in Yugoslavia: an econometric model.

"The paper analyzes the impact of external migration on the Yugoslav economy during the period 1965-1972. This is done by means of a macroeconometric model embodying various dualistic characteristics of Yugoslavia. A counterfactual simulation of the model is used to judge the impact of external migration. According to the indicators utilized, the simulation suggests that migration has been beneficial to Yugoslavia."
