Les effets du gel d'une caisse de retraite sur la performance et le risque des entreprises

This study considers the effect of freezing defined benefit pension funds on shareholder risk and returns. The conditional models used in this study directly assess the effects of a pension fund freeze on returns and on systematic and residual risk. While pension fund freezes do not significantly affect performance or systematic risk, they do significantly reduce short‐term residual risk. Pension fund freezes therefore do not generally present significant financial advantages to shareholders. Only shareholders of funds in crisis would benefit from significant systematic risk reductions. Copyright © 2015 ASAC. Published by John Wiley & Sons, Ltd.     

Effets des réglementations sur la rentabilité et le risque des compagnies d'assurances iard

La réglementation des sociétés d'assurances par les autorités de tutelle impose différentes contraintes aux gestionnaires. Il est difficile d'en apprécier les effets finaux si l'on ne dispose pas d'un modèle d'ensemble de l'entreprise. La rentabilité des compagnies d'assurances dépend de la gestion de l'actif et du passif du bilan, portefeuille déplacements et portefeuille d'assurances. La réglementation intervient pour poser des limites à ces choix sous forme de plafonds en pourcentages pour certains types de placements. Cette étude dans le contexte Canadien met en évidence le coǔt économique, en termes de risque et de rendement, d'une réglementation sur les placements. Abstract The control of insurance companies by the regulatory authorities imposes constraints on the manager's decisions. The companies' profitability is a function of the management of both assets and liabilities. Therefore it depends on the relative importance of the diverse lines of insurance - the insurance portfolio - and relative weight of the various assets - the investment portfolio. Portfolio theory demonstrates that the total risk is a non-linear combination of those component risks in a portfolio. This, in turn, determines the pursuit of the optimal portfolio structure, a structure defined by a minimal risk for a given level of profitability. With such a generalized portfolio model for insurance companies, one could simulate the consequences of the modification of any given regulation on either the assets or liabilities. The combination of risk level and profitability accessible to the companies vary as a function of markets constraints and regulations considered. It is therefore possible to demonstrate the effect, in terms of risk and return framework, of various regulations. The first section of this paper discusses the appropriate approach to the portfolio problem applied to insurance. The second section describes the data and the empirical results.     

Le modèle d'apprentissage de l'erreur et les taux de change à terme

Dans cette étude, nous utilisons le modèle d'apprentissage de l'erreur pour examiner le processus suivi par les agents économiques pour réviser les taux de change à terme, ceux-ci étant considérés comme des anticipations du taux de change au comptant futur. Nos résultats basés sur deux échantillons indiquent: 1) que le simple écoulement du temps n'a pas d'effet systématique sur la révision des taux de change à terme; 2) que les agents économiques semblent utiliser l'hypothèse plausible que les taux de change au comptant suivent une marche aléatoire; 3) que seulement quelques devises manifestent des possibilités d'inefficience. Abstract In this paper, the error-learning model is used to examine the updating process of forward exchange rates, these being considered as expected future spot rates. The results based on two samples show that:1) the mere passage of time does not have a systematic effect on the revision of forward exchange rates; 2) economic agents seem to use the plausible hypothesis that spot rates follow a random walk; 3) only a few currencies exhibit possibilities of inefficiency.     

Effets des conceptions de l'erreur,de la motivation à apprendre et du soutien social sur l'intention de transférer les nouveaux apprentissages : un modèle de médiation modérée

This study aims to assess whether trainees' errors orientation can influence their motivation to learn and their intention to transfer learning. Data were collected from 275 trainees participating in a corporate training program offered by a Canadian government agency. Results show that the concept of learning by error positively influences trainees' levels of motivation and their intention to transfer learning. Results also confirm the mediating role motivation plays between the concept of learning by error and the intention of transferring learning. Finally, results confirm the moderating role of social support on the relationship between motivation to learn and the intention to transfer learning. Practical and theoretical implications of these results are discussed. Copyright © 2017 ASAC. Published by John Wiley & Sons, Ltd.
