This paper breaks new ground toward contractual and institutional innovation in models of homeownership, equity building, and mortgage enforcement. Inspired by recent developments in the affordable housing sector and in other types of public financing schemes, this paper suggests extending...

A new model of unemployment based on an idea of Marx is presented and used to interpret the development of the British economy from the beginning of capitalism to the present. It is shown that unemployment may be created purposely by capitalists in order to weaken the bargaining position of the...

Ghoshs model is discussed in this paper under two alternative scenarios. In an open version we compare it with Leontiefs model and prove that they reduce to each other under some specific productive conditions. We then move onto reconsidering Ghoshs model alleged implausibility and we do so...

This expository paper describes the factors that contribute to failure of health insurance markets, and the regulatory mechanisms that have been and can be used to combat these failures.

Site licensing of electronic journals has been revolutionizing the way academic information is distributed. However, many librarians are concerned about the possibility that commercial publishers might abuse site licensing by practicing bundling. In this paper, we analyze how bundling afects...

We study a retail benchmarking approach to determine access prices for interconnected networks. Instead of considering fixed access charges as in the existing literature, we study access pricing rules that determine the access price that network i pays to network j as a linear function of the...

In this paper, we study how access pricing affects network competition when subscription demand is elastic and each network uses non-linear prices and can apply termination-based price discrimination. In the case of a fixed per minute termination charge, we find that a reduction of the...

We re-examine the literature on mobile termination in the presence of network externalities. Externalities arise when firms discriminate between on- and off-net calls or when subscription demand is elastic. This literature predicts that profit decreases and consumer surplus increases in...

In this paper we present a model of oligopoly and financial constraints. We study allocations which are bankruptcy-free (BF) in the sense that no firm can drive another firm to bankruptcy without becoming bankrupt. We show how such allocations can be sustained as an equilibrium of a dynamic...

I analyze the basis of the market economy in classical Rome, from the perspective of personal-versus-impersonal exchange and focusing on the role of the state in providing market-enabling institutions. I start by reviewing the central conflict in all exchanges between those holding and those...
