This paper surveys recent theoretical economic research on long term care (LTC). LTC differs from health care: it is about nursing; it is mostly provided by unpaid caregivers (mainly spouses and children), whereas both the market and the State play a modest role. The future of LTC appears to be...

Should health care provision be public, private, or both? We look at this question in a setting where people differ in their earnings capacity and express an inelastic demand for health care. We assume that illness reduces a person's health status when not receiving immediate treatment.

In this paper, we propose an example of successive oligopolies where the downstream firms share the same decreasing returns technology of the Cobb-Douglas type. We stress the differences between the conclusions obtained under this assumption and those resulting from the traditional example...

In the theoretical literature, strong arguments have been provided in support of the efficiency defense in antitrust merger policy. One of the most often cited results is due to Williamson (1968) that shows how relatively small reduction in cost could offset the deadweight loss of a large price...

This paper analyses successive markets where the intra-market linkage depends on the technology used to produce the final output. We investigate entry of new firms, when entry obtains by expanding the economy, as well as collusive agreements between firms. We highlight the differentiated effects...

This paper examines a three-stage model of divisionalization where, first, two parent firms create independent units, second, the parent firms allocate cost reduction levels over these units, and third, the resulting units compete in a Cournotmarket given their current costs of production. The...

The present work analyzes the effect of competition on managerial incentives when agents have private information about the firms' productivities. Two types of firms are considered: managerial firms (delegation) and entrepreneurial firms (no delegation). Due to the asymmetry of information...

In this paper we analyze how the technology used by downstream firms can influence input and output market prices. We show via an example that both these prices increase under a decreasing returns technology while the contrary holds when the technology is constant.

This paper faces two questions concerning Joint Ventures (JV) agreements. First, we study how the partners contribution affect the creation and the profit sharing of a JV when partners' effort is not observable. Then, we see whether such agreements are easier to enforce when the decision on JV...

In view of the uncertainty over the ability of merging firms to achieve efficiency gains, we model the post-merger situation as a Cournot oligopoly wherein the outsiders face uncertainty about the merged entity's final cost. At the Bayesian equilibrium, a bilateral merger is profitable provided...
