Recent capital market research evidence suggests that a large proportion of public companies worldwide are characterized by controlling stockholders who are more often families, usually the founder(s) or their descendants. There has been considerable debate on whether “family” firms can indeed be accurately delineated from nonfamily firms given the diversity and abundance of family business definitions in the literature. This paper provides a robust definition of family business for the purposes of capital market research. Using an accounting‐based definition of family business, the paper outlines a four‐step procedure that provides validation for identifying family controlled companies listed on the Australian Stock Exchange. A significant feature of the research methodology was reliance on data collected from the Australian Securities and Investments Commission. Having access to the corporate regulator's restricted data enabled the researchers to establish important links between directors and their private related entities. 相似文献

Several definitions of individual bioequivalence of two formulations of a medical treatment (drug) have been proposed recently. These definitions attempt to adapt the criterion of average bioequivalence, which would be deficient if substantive treatment heterogeneity were present. In some of the proposed definitions, relatively large differences of means can be compensated by differences in the measurement-error variances. We propose a definition based on a simple latent-variable model which overcomes this anomaly and need not involve the U.S. Food and Drug Administration's 80/125 rule. Our approach is based on a moment-matching estimator of the discrepancy between the outcomes underlying the subjects' responses. The distribution of this estimator is a linear combination of independent χ2 variates; asymptotically, it can be approximated by a normal distribution. Evidence of individual bioequivalence corresponds to rejecting the hypothesis that the discrepancy is greater than a specified threshold. The approach is illustrated by reanalysing two bioequivalence trials. 相似文献

To compete effectively, multi-national enterprises (MNEs) must establish market presence in their global rivals' home courts and/or profit sanctuaries. Technology transfer is often used as a means toward that end. The technology adoption decisions of an aggressor MNE and a defender MNE are investigated in a model that features indirect moves and changes in strategy through technology transfer. Each firm may adopt a strategy that incorporates the transfer of high technology or appropriate technology. The strategic decision situation is modelled as a closed-loop sequential equilibrium in discrete time. In contrast to results in the technology adoption literature, the aggressor MNE may successfully transfer technology first, to be imitated later by the defender MNE. This and several other scenarios emerge from the model which, by incorporating the cost of social adjustment and risks involved in technology transfer, ties technology to the competitive interaction of MNEs and specifies conditions for creating competitive advantage through technology, both locally and worldwide. 相似文献

We consider unit root testing allowing for a break in trend when partial information is available regarding the location of the break date. This takes the form of knowledge of a relatively narrow window of data within which the break takes place, should it occur at all. For such circumstances, we suggest employing a union of rejections strategy, which combines a unit root test that allows for a trend break somewhere within the window with a unit root test that makes no allowance for a trend break. Asymptotic and finite sample evidence shows that our suggested strategy works well, provided that, when a break does occur, the partial information is correct. An empirical application to UK interest rate data containing the 1973 ‘oil shock’ is also considered. 相似文献

The Effect of Country‐Level Investor Protection on the Voluntary Assurance of Sustainability Reports
David N. Herda Martin E. Taylor Glyn Winterbotham 《Journal of International Financial Management & Accounting》2014,25(2):209-236
Over the last several years, sustainable (or socially responsible) investing has experienced rapid growth around the world reflecting an increasing awareness by investors of social, environmental, ethical, and corporate governance issues. This heightened awareness among investors has resulted in a demand for sustainability reporting and a corresponding increase in demand for assurance of sustainability information to enhance its credibility. Using an investor‐based view, we examine the impact of country‐level investor protection on reporting companies’ voluntary sustainability assurance decisions. We find that both the decision to obtain voluntary sustainability report assurance and the decision to obtain higher quality assurance are more likely for firms domiciled in countries that have weaker investor protection. Our results indicate that managers in low investor protection countries use voluntary sustainability assurance as a substitute monitoring mechanism. 相似文献
