Acid rain is caused by sulphur dioxide (SO2), largely from power stations, and nitrogen oxides (NOx), half of which comes from vehicles. The paper attempts to quantify the costs and benefits of abatement in Europe, and concludes that the current agreement on uniform reductions from 1980 levels...

Patient mobility is a key issue in the EU who recently passed a new law on patients' right to EU-wide provider choice. In this paper we use a Hotelling model with two regions that differ in technology to study the impact of patient mobility on health care quality, health care financing and...

Under Medicare Part D, senior citizens choose prescription drug insurance offred by numerous private insurers. We examine non-poor enrollees' actions in 2006 and 2007 using panel data. Our sample reduced overspending by $298 on average, with gains by 81% of them. The greatest improvements were...

Performance indicators are increasingly used to regulate quality in health care and other areas of the public sector. We develop a model of contracting between a purchaser (principal) and a provider (agent) under the following scenarios: a) higher ability increases quality directly and...

One of the mechanisms that is implemented in the cost containment wave in the health-care sectors in western countries is the definition, by the third-party payer, of a set of preferred providers. The insured patients have different access rules to such providers when ill. The rules specify the...

Extending choice in health care is currently popular amongst English, and other, politicians. Those promoting choice make an appeal to a simple economic argument. Competitive pressure helps make private firms more efficient and consumer choice acts as a major driver for efficiency. Giving...

The Paper evaluates the German health care reform of 1997, using the individual number of doctor visits as outcome measure. A new econometric model, the Probit-Poisson-log-normal model with correlated errors, describes the data better than existing count data models. Moreover, it has an...

We investigate the effect of competition on quality in regulated markets (e.g., health care, higher education, public utilities), using a Hotelling framework, in the presence of sluggish demand. We take a differential game approach, and derive the open-loop solution (providers commit to an...

We investigate the effect of competition on quality in regulated markets (e.g., health care, higher education, public utilities) taking a differential game approach, in which quality is a stock variable. Using a Hotelling framework, we derive the open-loop solution (providers commit to an...

We study optimal risk adjustment in imperfectly competitive health insurance markets when high-risk consumers are less likely to switch insurer than low-risk consumers. First, we find that insurers still have an incentive to select even if risk adjustment perfectly corrects for cost differences...
