TAUX D'INTERET EFFECTIF, VIABILITE FINANCIERE ET FINANCEMENT DES PETITS OPERATEURS ECONOMIQUES PAR LES INSTITUTIONS DE MICROFINANCE AU BENIN

RÉSUMÉ ** :  Les institutions de microfinance (IMF) ont accompli le miracle de faciliter l'accès aux services financiers à des milliers d'exclus du système bancaire classique dans les pays en développement. Mais une polémique naît quant aux coûts élevés associés auxdits services. Cette étude a évalué le niveau de taux d'intérêt viable pour la microfinance en termes d'offre de services financiers. Les résultats montrent que les micro-projets dont le taux de rentabilité interne ne dépasse pas 42% ne pourraient être financés par les institutions de microfinance. Quasiment aucune IMF n'assurerait son autosuffisance opérationnelle, donc sa pérennité en respectant le seuil légal fixéà 27%.     

Perceptions of high‐involvement work practices and burnout: the mediating role of job demands

This study examined the impact of perceived high‐involvement work practices on job demands (role conflict, role overload and role ambiguity) and burnout (emotional exhaustion and depersonalisation). The study was conducted in a Canadian general hospital. Findings from structural equation modelling (N = 545) revealed that perceived HIWPs were significantly and negatively related to job demands and burnout. Role conflict and role overload have a significant positive association with emotional exhaustion and depersonalisation. Finally, role conflict and role overload partially mediate the relationship between perceived HIWPs and burnout. We discuss the theoretical and managerial implications of these findings for our understanding of how HIWPs influence the job demands and burnout of employees.     

A pseudo-panel data model of household electricity demand

We study the dynamic behaviour of household electricity consumption on the basis of four large independent surveys conducted in the province of Québec from 1989 to 2002. The latter region displays some rather unique features such as the very extensive use of electricity for space heating in a cold climate and the wide range of energy sources used to meet space heating requirements. We adopt Deaton (1985) approach to create 25 cohorts of households that form a pseudo-panel. The cohorts have on average 131 households. The model error terms allow for group heteroskedasticity and serial correlation. Short-run and long-run own and cross-price elasticities are statistically significant. Electricity and natural gas are estimated to be substitutes while electricity and fuel oil are complements, as it may occur in the Quebec context. The estimate of the income elasticity is not significant. Comparisons with related studies are provided.     

Rebounding from Corruption: Perceptions of Ethics Program Effectiveness in a Public Sector Organization

We examine the perceived importance of three organizational preconditions (awareness of formal ethics codes, decision-making techniques, and availability of resources) theorized to be critical for ethics program effectiveness. In addition, we examine the importance of ethical leadership and congruence between formal ethics codes and informal ethical norms in influencing employee perceptions. Participants (n=418) from a large southern California government agency completed a survey on the perceived effectiveness of the organization’s ethics program. Results suggest that employee perceptions of organizational preconditions, ethical leadership and informal ethical norms were related to perceptions of ethics program effectiveness. Based on these findings, organizations should evaluate the presence (or absence) of essential preconditions and take steps to ensure that leaders model espoused organizational values to foster perceptions of effective ethics programs.Kathie L.

An investigation of the weekend effect during different market orientations

Studies of stock returns over short horizons indicated irregularities in returns, the weekend effect, and consequently the notion of market efficiency has been questioned. Despite extensive research on the weekend effect, little research has been conducted to define the prominence of the seasonal anomaly in Bear markets versus non-Bear markets. In the paper the weekend effect is investigated for daily returns in the Dow Jones Industrial Average (DJIA), the S&P 500, and the NASDAQ for Bear and non-Bear markets. Results support a weekend effect but only during non-Bear market orientations and a possible day-of-the-week effect during Bear and non-Bear markets.     

Equity recognition of mandatory accounting changes: the case of transitional goodwill impairment losses

This study investigates if and how the use of the retroactive method to account for a mandatory accounting change affects a firm's measurement and recognition choices. We examine if reporting incentives and constraints are associated with the magnitude of transitional goodwill impairment losses reported by Canadian firms implementing Section 3062 on purchased goodwill. Our results indicate firms have an incentive to both overstate and understate transitional goodwill impairment losses. We also show that financially literate and independent audit committees constrain managerial opportunism. Copyright © 2008 ASAC. Published by John Wiley & Sons, Ltd.
