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...

We develop a model of waiting lists for public hospitals when physicians deliver both private and public treatment. Public treatment is free but rationed, i.e., only cases meeting some medical criteria are admitted for treatment. Private treatment has no waiting time but entails payment of a...

Depending on the definition of the tax base, the statutory corporate tax rate implies rather different measures of effective average and marginal tax rates. This paper develops a model of a monopolistically competitive industry with extensive and intensive business investment and shows how these...

We analyse a set of simple dynamic models where sellers are capacity constrained over the length of the model. Buyers act strategically in the market, knowing that their purchases may affect future prices. The model is examined when there are single and multiple buyers, with both linear and...

This paper investigates the interaction of firms' financial structure and their competitive behaviour on oligopolistic product markets. We consider risk-averse entrepreneurs who produce with uncertain production costs. To reduce their exposure to risk they can sell stocks to risk-neutral...

We set up a duopoly model with dynamic capacity constraints under demand uncertainty. We endogenize the investment decisions of the firms, examine their intertemporal pricing behavior, their incentives to merge, as well as the welfare implications of a merger. Whereas under known and constant...

The Paper addresses the issue of coordinated effects of mergers in the framework of a differentiated products model. Firms’ assets are product varieties that can be sold individually or entirely transferred to another firm in a merger. We show that under symmetric optimal punishment schemes...

We present a Hotelling model of price and advertising competition between prescription drugs that differ in quality/side e¤ects. Advertising results in the endogenous formation of two consumer groups: brand loyal and non-brand loyal ones. We show that advertising strategies are strategic...
