We address the question of how a third-party payer (e.g. an insurer) decides what providers to contract with. Two different mechanisms are studied and their properties compared. A first mechanism consists in the third party payer setting up a bargaining procedure with both providers. The second...

The interpretation of the loss of utility as transport costs in address models of differentiation poses a methodological difficulty. Transport costs implicitly amounts to assume that there is a good neither included in the differentiated sector nor in the composite (numeraire) good of the...

In several instances, third-party payers negotiate prices of health care services with providers. We show that a third-party payer may prefer to deal with a professional association than with the sub-set constituted by the more efficient providers, and then apply the same price to all providers....

This paper aims at assessing the importance of the initial technological endowments when firms decide to create R&D agreements. We study a Bertrand duopoly where firms evaluate the returns of an agreement according to its length. A learning process allows us to depict a close connection between...

Ramsey pricing has been proposed in the pharmaceutical industry as a principle to price discriminate among markets while allowing to recover the (fixed) R&D cost. However, such analyses neglect the presence of insurance or the fund raising costs for drug reimbursement. By incorporating these new...
