Within a traditional context of myopic discrete-time mean-variance portfolio investments, the problem of conditioned optimisation, in which predictive information about returns contained in a signal is used to inform the choice of portfolio weights, was first expressed and solved in concrete...

Abstract: This paper investigates the effect of anticipated/experienced regret and pride on individual investors decisions to hold or sell a winning or losing investment, in the form of the disposition effect. As expected the results suggest that in the loss domain, low anticipated regret...

Remittances have greatly increased during recent years, becoming an important and reliable source of funds for many developing countries. Therefore, there is a strong incentive for receiving countries to attract more remittances, especially through formal channels. One way of doing so is to...

In this paper we first introduce an approach relying on market games to examine how successive oligopolies operate between downstream and upstream markets. This approach is then compared with the traditional analysis of oligopolistic interaction in successive markets. The market outcomes...

In this paper, we propose an example of successive oligopolies where the downstream firms share the same decreasing returns technology of the Cobb-Douglas type. We stress the differences between the conclusions obtained under the assumption and those resulting from the traditional example...

Substitution policies are strategies sometimes chosen in Sub-Saharan Africa for curtailing the shortage of health professionals especially caused by the outflow of medical personnel. The aim of our contribution is to propose a way to assess the merits and drawbacks of substitution policies by...

We investigate the existence of local (i.e. within-country) and global (i.e. between-country) knowledge spillovers within a single analytical framework. Our analysis is based on an exhaustive database on Irish manufacturing plants covering the period 1986-1994 and focuses on the impact of R&D...

We argue that the failure to disentangle the evolution of the Canadian currency and energy and commodity prices from the US currency leads to potential wrong conclusions regarding the case of a Dutch disease in Canada. We propose a new approach aimed at extracting currency components and energy...

The pace of international skilled migration has accelerated dur- ing recent decades and it has attracted considerable attention across scholars and politicians. This paper gives a general and critical idea of the brain drain issue. It provides stylized facts on the magnitude and skill...

The aim of this paper is to develop a dynamic model of migra- tions, in which migration is driven by size asymmetries between coun- tries and by the relative preferences of consumers between private consumption and consumption of public goods. The dynamic trajec- tories heavily depend on the...
