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%. 相似文献

Critics of U.S. corporations have long argued that companies are overly focused on short‐term results and, as a consequence, sacrifice their own long‐run value and competitiveness. These criticisms have expanded in recent years to include those from prominent politicians, investors, consultants, and academics. If such criticisms have merit, they would imply a massive governance failure in which there has been decades of underinvestment with little adjustment on the part of managers, boards, or the market for corporate control. This article evaluates the economic underpinnings of these criticisms and analyzes their implications in the context of empirical evidence produced by several decades of research on corporate investment policies, the outcomes of corporate control events, investor horizons, and the market pricing of companies with little if any earnings. In reviewing the findings of these studies, the author finds little evidence to support the view that U.S. companies sacrifice long‐run value and competitiveness by systematically underinvesting. First, although U.S. companies have indeed cut back on tangible investments such as property, plant, and equipment, these cutbacks have been more than offset by the dramatic growth in investment in intangibles, such as spending on developing knowledge capital, brand‐building, and IT infrastructure. Second, when subjected to events that have the effect of reducing managerial control over investment policies and transferring control to outside investors—such as leveraged buyouts and recapitalizations, forced CEO dismissals, and shareholder activist campaigns—companies tend to reduce, not increase, investment spending. In fact, it is difficult to find any corporate control threats that have had the goal or effect of increasing investment. Third, and at the same time, the rising concentration of large institutional investors, including indexers such as BlackRock and Vanguard, suggests that investors have become, if anything, more long‐term oriented over time. Fourth, there is no evidence that the market shuns companies that have yet to report large (or indeed any) earnings. These findings suggest that curbing overinvestment, and not discouraging myopia and underinvestment, may well still be the larger corporate governance challenge facing investors when monitoring and attempting to influence the performance of U.S. companies. 相似文献

The aim of this paper is to investigate the relevance for stock market pricing of accounting earnings of voluntary disclosures in XBRL files considering the quality of corporate governance. Results are the following. It appears that XBRL extensions attract financial analysts. Good governance is positively associated with voluntary XBRL extensions. We observe that XBRL extensions enhance the positive relationship between accounting earnings and stock price. However, this positive association is reduced for firms with good governance, suggesting a substitution effect between XBRL extensions and corporate governance. Finally, it appears that XBRL extensions would strategically be related to earnings quality. This research highlights the importance to consider governance when assessing the value relevance of XBRL disclosures for stock market pricing. 相似文献

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. 相似文献

This article investigates differences in household production and consumption among small‐ and large‐scale irrigators to assess whether the scale of an irrigation project increases household welfare in Mali. Much of the evidence of the impact of irrigation does not use counterfactual analysis to estimate such impact or distinguish between the scale of the irrigation projects to be evaluated. In the dataset collected by the author, both a large‐scale irrigation project and small‐scale projects are used to construct counterfactual groups. Propensity score matching is used to estimate the average treatment effect on the treated for small and large irrigators relative to non‐irrigators on agricultural production, agricultural income and consumption per capita. Small‐scale irrigation has a larger effect on agricultural production and agricultural income than large‐scale irrigation, but large‐scale irrigation has a larger effect on consumption per capita. This suggests that market integration and non‐farm externalities are important in realising gains in agricultural surplus from irrigation. 相似文献

In contrast with the classical models of frictionless financial markets, market models with proportional transaction costs,
even satisfying usual no-arbitrage properties, may admit arbitrage opportunities of the second kind. This means that there
are self-financing portfolios with initial endowments lying outside the solvency region but ending inside. Such a phenomenon
was discovered by M. Rásonyi in the discrete-time framework. In this note, we consider a rather abstract continuous-time setting
and prove necessary and sufficient conditions for a property which we call no free lunch of the second kind, NFL2. We provide a number of equivalent conditions elucidating, in particular, the financial meaning of the property B which appeared as an indispensable “technical” hypothesis in previous papers on hedging (superreplication) of contingent
claims under transaction costs. We show that it is equivalent to another condition on the “richness” of the set of consistent
price systems, close to the condition PCE introduced by Rásonyi. In the last section, we deduce the Rásonyi theorem from our general result by using specific features
of discrete-time models. 相似文献

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. 相似文献
