We propose a model based on competitive markets in order to analyse an economy with several homogeneous landlords and heterogeneous tenants. We model the landlord- tenant economy as a two-sided matching game and characterise the equilibrium of this market. In equilibrium, contracts are Pareto...

There are two general ways in which the role of fiat money has been introduced in the standard monetary search-theoretical model. The first is to bring in the model a fiat object with different intrinsic properties. The second is to introduce a centralized institution that favors the use of fiat...

We conduct a laboratory experiment to study how, after a history of decay, cooperation in a repeated voluntary contribution game can be revived in an enduring way. Simply starting the repeated game over - a simple fresh start - leads to an initial increase of cooperation, but to a subsequent new...

We consider a dynamic model where traders in each period are matched randomly into pairs who then bargain about the division of a fixed surplus. When agreement is reached the traders leave the market. Traders who do not come to an agreement return next period in which they will be matched again,...

This paper generalizes the original random matching model of money by Kiyotaki and Wright (1989) (KW) in two aspects: first, the economy is characterized by an arbitrary distribution of agents who specialize in producing a particular consumption good; and second, these agents have preferences...

This paper analyses the effect of unmet formal care needs on informal caregiving hours in Spain using the two waves of the Informal Support Survey (1994, 2004). Testing for double sample selection from formal care receipt and the emergence of unmet needs provides evidence that the omission of...

This paper addresses the impact of payment systems on the rate of technology adoption. We present a model where technological shift is driven by demand uncertainty, increased patients benefit, financial variables, and the reimbursement system to providers. Two payment systems are studied: cost...

Recently the Portuguese Government announced the launching of public private partnerships to build hospitals with the distinctive feature that both infrastructure construction and the clinical activities management will be awarded to a private party. Accordingly there appear coordination issues...

A feature present in countries with a National Health Service is the coexistence of a public and a private sector. Often, the public payer contracts with private providers while holding idle capacity. This is often seen as inefficiency from the management of public facilities. We present here a...

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....
