In this paper we show that if a very small, exogenously given probability of terminating the exchange is introduced in an elementary investment game, reciprocators play more often the defection strategy. Everything happens as if they "hide behind probabilities" in order to break the trust...

This paper explores the methodological implications of non-representational approaches of organizational complexity. Representational theories focus on the syntactic complexity of systems, whereas organizing processes are predominantly characterized by semantic and pragmatic forms of complexity....

One possible way of risk management for an insurance company is to develop an early and appropriate alarm system before the possible ruin. The ruin is defined through the status of the aggregate risk process, which in turn is determined by premium accumulation as well as claim settlement out-go...

We propose a method to generate a warning system for the early detection of time clusters in discrete time series. Two approaches are developed, one using an approximation of the return period of an extreme event, independently of the nature of the data, the other using an estimation of the...

This article discusses conflicts of interest existing between investors and their financial advisors. Several contributions in this field treated this question in relation either with invested amount or with expected holding period of the mutual fund. Our paper considers an approach globalizing...

This article analyzes how the actual and expected future activities of French Socially Responsible Investment (SRI) analysts may reveal a convergence process between SRI decisions and traditional financial investment decisions, that is a form of “mainstreaming” of SRI processes, by asking...

The authors analyse the present and coming financial consequences of the revolution caused by the new communication media (TV broadcast, DVD, internet…) towards the diffusion of literary and artistic works protected by intellectual property laws to an increasingly larger public. They...

This paper analyzes international migrations when migrants invest part of their income in their origin country. This investment contributes to increase capital intensity and wages in the origin country, thus reducing the scope for migrating. We show that a non-total migratory equilibrium can...

This original study examines the potential of a spatiotemporal autoregressive Local (LSTAR) approach in modelling transaction prices for the housing market in inner Paris. We use a data set from the Paris Region notary office (“Chambre des notaires d’Île-de-France”) which consists of...

This paper studies the influential Melitz model of trade with heterogeneous firms using an alternative, intuitive approach. Contrary to what is often argued, it is an increase in product market competition that drives the bad firms out: with two-way trade, entry by foreign firms is not...
