The World Health Assembly passed a resolution on the importance of engaging with the private health sector. However, the reality is that universal health coverage aspirations are particularly challenging when there is a significant private health sector. This sector in South Africa suffers from rapidly increasing costs, inflation and volume of services (unnecessary medical tests or treatments)....

We present an empirical analysis of a supply function equilibrium model in the Texas spot electricity market. We derive conditions for optimal bidding behavior in a spot market with ex ante bilaterally contracted sales. By estimating costs, we are able to derive a set of ex post-and ex ante-optimal supply functions and use a non-parametric behavioral model to compare our theoretically optimal s...

Highly palatable foods play a salient role in obesity and binge-eating, and if habitually eaten to deal with intrinsic and extrinsic factors unrelated to metabolic need, may compromise adaptive coping and interpersonal skills. This study used event sampling methodology (ESM) to examine whether individuals who report eating palatable foods primarily to cope, to enhance reward, to be social, or t...

As a contribution to the understanding of the mechanism of the collective motion of the cell mass in the migrating pseudoplasmodium its motive force has been determined. The measurements in the present paper were made by an original method using centrifugal force. The maximum value of the motive force of a migrating pseudoplasmodium in the dark was estimated as 0.6-1.6 dyn. This value is compar...

subject written in England and primarily for English readers. The book is not intended merely for the medical profession, though most medical officers will read it with profit; it is a popular handbook and is written like the same author's Medical Jurisprudence mainly for non-professional readers and consequently in clear and simple language. In addition to being a book on Hygiene, it also deal...

AIM This paper provides a critical overview a decade after the New Zealand Government announced its intention to formally incorporate a public health approach into its comprehensive revision of gambling legislation. METHOD The initial enthusiasm and the subsequent disillusionment with this approach are tracked. Four reasons for its lack of success are examined. FINDINGS The New Zealand expe...

The nature of competition is quite different in network industries as compared to the other, more traditional, ones. The purpose of the present paper is to thoroughly examine the implications of these differences as reflected in the dependence of equilibrium outputs, price and profits on industry concentration. We restrict the analysis to oligopolistic competition amongst firms in a market char...

If a hospital is to use profit centers successfully, it should resolve several philosophical, organizational, and accounting matters, including: How much decisionmaking latitude clinical care chiefs should have. Whether to take a cross-subsidization approach. What role clinical care departments should take in a service line strategy.

About 25% of the world's fisheries are depleted such that their current biomass is lower than the level that would maximize the sustained yield (MSY). By using methods not previously applied in the fisheries conservation context, we show in four disparate fisheries (including the long-lived and slow-growing orange roughy) that the dynamic maximum economic yield (MEY), the biomass that produces ...

This paper examines how a project owner optimally selects a project operator and motivates him to deliver an unobservable effort when potential operators are wealthconstrained. It shows that either a pooling or a separating contract can arise in equilibrium. In a separating contract, the more capable potential operator is either selected more often but awarded a smaller share of profit, or sele...
