The paper examines how hospital cost efficiency has reacted to extensive horizontal integrations of hospitals and rapid growth of managed care in the US health care industry. Cost efficiency is estimated by using panel data approaches to relax the assumptions for the hospital effects imposed in earlier studies. The paper shows that higher managed care penetration over time is associated with gr...

This paper considers a model of defensive medicine where doctors are imperfect agents of insured patients. A national insurer subsidises both curative and preventive medical care consumed by risk averse patients. We show that in such an environment, the optimal liability regime is similar to the no-fault systems of Sweden and New Zealand where the doctor faces zero liability. The reason is that...

HE tryptophan-I ( t r yp I ) locus is located in linkage group I11 in Neurospora crassa. TATUM and BONNER (1944) and BEADLE and TATUM (1945) reported tryp-I mutant 10575, which could utilise either indole or tryptophan. AHMAD and CATCHESIDE (1960) brought forward evidence that a new group of five anthranilic acid mutants were allelic to 10575. The present paper describes complementation studies...

This article presents a model to analyze consumer welfare, price, and competition in a three-way market among consumers, medical providers, and insurers. While insurers compete with each other for customers, they also act as collective bargaining agents on behalf of consumers in determining the equilibrium price of health care with providers. The entry of an additional insurer thus has contradi...

The influence of Eu3+ on the upconversion (UC) fluorescence of Er3+ in Y2O3:Er, Yb3+ nanocrystals was investigated. Room-temperature UC spectra show that the intensity ratio of red to green lights was increased from 8.6 to 19.3 with 1.0 mol% Eu3+ doping. Additionally, with the increase of Eu3+ ion concentration, the n values for both green and red UC emissions in Y2O3:Er, Yb3+ nanocrystals beco...

Though most of the literature in health insurance and the labor market assumes a tradeoff between employerprovided health insurance and wages, its empirical validity has not been established. Employing Current Population Survey 2004 data, this paper assesses the tradeoff hypothesis in a distributional analysis framework using stochastic dominance tests. In addition, it contributes to the previo...

This paper revisits the link between health insurance and health by estimating a model that allows for insurance and health to be linked through both dynamic and contemporaneous channels, each with di¤erent policy implications. The model produces two main …ndings. First, while insurance and health appear to be negatively related dynamically, they are positively related contemporaneously, with p...

New empirical evidence shows substantial heterogeneity in the altruism of healthcare providers. Spurred by this evidence, we build a spatial quality competition model with altruism heterogeneity. We fi nd that more altruistic healthcare providers supply relatively higher quality levels and position themselves closer to the center. Whether the social planner prefers more or less horizontal diff ...
