TLDR
A model for interdependent demand for health insurance and health care under uncertainty is developed to throw light on the issue of insurance-induced distortions in thedemand for health care services.Abstract:
This paper develops a model for interdependent demand for health insurance and health care under uncertainty to throw light on the issue of insurance-induced distortions in the demand for health care services. The model is used to empirically analyse the determinants of the choice of health insurance type and seven types of health care services using micro-level data from the 1977–78 Australian Health Survey. Econometric implementation of the model involves, simultaneously, issues of discreteness of choice, selectivity and stochastic dependence between health insurance and utilization. Health status appears to be more important in determining health care service use than health insurance choice, while income appears to be more important in determining health insurance choice than in determining health care service use. For a broad range of health care services both moral hazard and self selection are found to be important determinants of utilization of health care services.read more

Hausman Tests for Inefficient Estimators: Application to Demand for Health Care Service
TL;DR: The Hausman (1978) test is based on the vector of differences of two estimators as discussed by the authors, and it is usually assumed that one of the estimators is fully efficient, since this simplifies calculation of the test statistic.

Information Asymmetries and Risk Management in Healthcare Markets: The U.S. Affordable Care Act in Retrospect
TL;DR: This article critically examines the pertinent issues in ex ante and ex post moral hazard in healthcare markets, with the U.S. Affordable Care Act (ACA) as its focal point of inquiry, and compares the various types of information asymmetries resulting from the production, allocation, and utilization of health insurance.

Specification Tests in Econometrics
TL;DR: In this article, the null hypothesis of no misspecification was used to show that an asymptotically efficient estimator must have zero covariance with its difference from a consistent but asymptonically inefficient estimator, and specification tests for a number of model specifications in econometrics.

Uncertainty and the Welfare Economics of Medical Care
TL;DR: In this article, the authors focus on the way in which the operation of the medical-care industry and the efficacy with which it satisfies the needs of society differ from a norm, and the most obvious distinguishing characteristics of an individual's demand for medical services is that it is not steady in origin as, for example, for food or clothing but is irregular and unpredictable.

Dummy Endogenous Variables in a Simultaneous Equation System
TL;DR: In this article, the authors considered the formulation and estimation of simultaneous equation models with both discrete and continuous endogenous variables and proposed a statistical model that is sufficiently rich to encompass the classical simultaneous equation model for continuous endogenous variable and more recent models for purely discrete endogenous variables as special cases of a more general model.

Econometric models based on count data. Comparisons and applications of some estimators and tests
TL;DR: In this article, the authors deal with specification, estimation and tests of single equation reduced form type equations in which the dependent variable takes only non-negative integer values, and provide a detailed application of the estimators and tests to a model of the number of doctor consultations.

TL;DR: In this paper, the authors used a subsample of the 1975 survey of 3249 households carried out by the Washington Center for Metropolitan Studies (WCMS) for the Federal Energy Administration for the purpose of testing the statistical exogeneity of appliance dummy variables typically included in demand for electricity equations.
