The author dissects, with great acuteness, the issues of convergence in financial performance dynamics in the African continent through the lenses of stock market capitalization, value traded, turnover, and number of listed companies. The empirical evidence is premised on 11 homogeneous panels based on regions (Sub-Saharan and North Africa), income levels (low, middle, lower-middle, and upper-middle), legal origins (English common law and French civil law), and religious dominations (Christianity and Islam). Findings provide partial support for the existence of absolute convergence in some dynamics. Only Sub-Saharan Africa reveals conditional convergence in relation to per capita number of listed companies. The speed of convergence for the most part is between 12% and 28% per annum. As a policy implication, countries should work toward adopting common institutional and structural characteristics that favor stock market development.  相似文献

State regulation of rates is sometimes used as a means to make automobile insurance more affordable to consumers by restricting insurer profits and pricing practices. Incentive distortions arising from this type of rate regulation might lead to higher accident rates and higher insurance loss costs. Annual state‐level panel data for the time period 1980–1998 are used to investigate these effects, using empirical methods that recognize the endogenous determination of states’ regulatory choices. Results suggest that rate regulation that systematically suppresses (some or all) drivers’ insurance premiums is associated with significantly higher average loss costs and higher insurance claim frequency.  相似文献

It is widely believed that international financial reporting standards (IFRS) have been adopted in many countries, at least for the consolidated reporting of listed companies. However, in nearly all cases, what the rules require is some national or supranational version of IFRS. This might create problems for investor confidence and comparability. We examine what companies and auditors report concerning compliance with IFRS, focusing on the first full year of IFRS reporting by companies in the stock market indices of four major European countries and Australia. We find that, even when companies were complying with IFRS, they were generally not saying so, which seems to miss part of the point of the 35‐year project on international harmonization. In a small number of cases, auditors provided dual reports: on full IFRS in addition to the mandated reference to national GAAP where the latter corresponds with full IFRS. These cases were found only in Germany and the United Kingdom, and mainly related to companies that filed with the Securities and Exchange Commission as foreign private issuers. We propose explanations for the general lack of dual reports and for the exceptions. We call for widespread adoption of dual reporting where a plain report on IFRS is not yet possible.  相似文献

The finite sample properties of three semiparametric estimators, several versions of the modified rescaled range, MRR, and three versions of the GHURST estimator are investigated. Their power and size for testing for long memory under short-run effects, joint short and long-run effects, heteroscedasticity andt-distributions are given using Monte Carlo methods. The MRR with the Bartlett window is generally robust with the disadvantage of a relatively small power. The trimmed Whittle likelihood has high power in general and is robust except for large short-run effects. The tests are applied to changes in exchange rate series (daily data) of 6 major countries. The hypothesis of no fractional integration is rejected for none of the series.  相似文献

Organ transplantation holds the potential to substantially restore the health of many otherwise terminally ill patients. That potential, however, is currently being denied full realization by a chronic and severe shortage of cadaveric organs that are made available for this use. In recent years, medical practitioners, social scientists, and others have debated the virtues of allowing markets for cadaveric organs to form as a way to end the current shortage. In this debate, market opponents have argued, inter alia, that (1) organ collections may fall with payment of positive prices and (2) the price required to equilibrate organ supply and demand would be high. On the other hand, proponents of organ markets have argued that financial inducements could save many lives and that the equilibrium price is likely to be low. While dozens of papers have been published debating this issue, to date no one has provided any empirical evidence to resolve these important questions of supply. This paper provides preliminary evidence suggesting that potential donors would be relatively responsive to financial inducements and, accordingly, that the price required to eliminate the current shortage of organs is surprisingly low.

In this article, policy capturing was used to examine how lawyers, as experts, understand the wording in employee handbook passages that promise procedural protections for employees. Specifically, how the wording of employee handbook passages can create both legal and nonlegal obligations was examined. Forty-six lawyers were asked to make the following judgments: whether the handbook passage constituted a legal or moral obligation and the chances of the employer winning or being granted a summary judgment in a wrongful discharge suit. Five aspects of the handbook passages were examined: verb strength, specificity, contract disclaimers, legalistic jargon, and the employee's signature.  相似文献

\"This paper tests a central prediction of vintage growth models of urban structure: that there are discontinuities in the population density function. The data set covers quarter sections in Chicago in 1980. Using such highly disaggregated data is critical because discontinuities are less likely to be found the larger is the unit of observation. Both a switching regression model and a nonparametric estimator reveal discontinuities and upward-sloping segments in the function, which supports the vintage growth model.\"  相似文献

We investigate how closely NBA teams play up to their potential. We find that shooting, rebounding, stealing the ball and blocking shots raise the number of potential wins while turnovers lower it. We also learn that better coaching and defensive prowess raise a team's win efficiency. Copyright © 2006 John Wiley & Sons, Ltd.  相似文献
