We show that the invariant method (Pinski and Narin, 1976), recently axiomatised by Palacios-Huerta and Volij (2004), and used to quality-rank academic journals is subject to manipulation: a journal can boost its performance by making additional citations to other journals.

In this paper we develop a model to describe a firm’s demand for two production factors which is subject to the presence of nonconvex adjustment costs. In our model simultaneous adjustment of these two production factors may either increase or decrease the total costs incurred by the firm. The...

We introduce and study a unified reasoning process which allows to represent the beliefs of both a fully rational agent and of an unaware one. This reasoning process provides natural properties to introspection and unawareness. The corresponding model for the rational or boundedly rational...

The present paper extends the standard model of pairwise communication among Bayesianagents to cases where the structure of the communication protocol is not commonly known.We show that, even under strict conditions on the structure of the protocols and the nature of the transmitted signals, a...

We introduce a new class of bankruptcy problems in which the value of the estate is endogenous and depends on agents'' investment decisions. There are two investment alternatives: investing in a company and becoming a shareholder (risky asset) and depositing money into a savings account...

Bloch (1996) presents a novel method to solve cooperative games with externalities. When trying to relate this to classical approaches he could only present negative results. We elaborate on these problems, define a modification of Bloch''s model and show that its order-independent equilibria...

By distinguishing between discretionary and non-discretionary fiscal policy, this paper analyses the stability of fiscal rules for EMU countries before and after the Maastricht Treaty. Using both Instrumental Variables and GMM techniques, it turns out that discretionary fiscal policy has...

This paper investigates the state, development and drivers of banking market integration in the member countries of the Southern African Development Community (SADC) by employing interest rate data. We first conduct a principal component analysis and find evidence for both increasing monetary...

We examine product-games, which are n-player stochastic games satisfying: (1) the state space is a product S(1)×…×S(n); (2) the action space of any player i only depends of the i-th coordinate of the state; (3) the transition probability of moving from s(i) ∈ S(i) to t(i) ∈S(i), on the...

This paper deals with the optimization of the flow of sterile instruments in hospital which takes place between the sterilization department and the operating theatre. This topic is especially of interest in view of the current attempts of hospitals to cut costs by outsourcing sterilization...
