This article considers a linear regression model with some missing observations on the response variable and presents two
estimators of regression coefficients employing the approach of minimum risk estimation. Small disturbance asymptotic properties
of these estimators along with the traditional unbiased estimator are analyzed and conditions, that are easy to check in practice,
for the superiority of one estimator over the other are derived.

Two readings are made of Mynatt, Omundson, Schroeder and Stevens (pp. 657–683). The first reading views the paper through a largely “conventional” social science lens, while the second adopts a more critical perspective which raises three issues: abstraction in research; gender and ethnicity; and the rhetoric of research. 相似文献

This study explores the impact of environmental turbulence on relationships between personal and organizational characteristics, personal values, ethical perceptions, and behavioral intentions. A causal model is tested using data obtained from a national sample of marketing research professionals in South Africa. The findings suggest turbulent conditions lead professionals to report stronger values and ethical norms, but less ethical behavioral intentions. Implications are drawn for organizations confronting growing turbulence in their external environments. A number of suggestions are made for ongoing research.

By means of a straightforward application of empirical process theory, we show that S-estimators of multivariate location and covariance are asymptotically equivalent to a sum of independent vector and matrix valued random elements respectively. This provides an alternative proof of asymptotic normality of S-estimators and clearly explains the limiting covariance structure. It also leads to a relatively simple proof of asymptotic normality of the length of the shortest α-fraction. 相似文献

Proponents of state antitakeover legislation argue that previous empirical tests by financial economists of the wealth effects of Pennsylvania's 1990 antitakeover law are biased. We show that the proponents are correct. In particular, firm size, event-time clustering, and non-synchronous trading effects account for the wealth decreases reported in earlier studies. We also show, however, that both proponents and critics of the Pennsylvania legislation have ignored the earliest press release about it. The wealth effect associated with this announcement is negative, large, and statistically significant. These results therefore are consistent with the hypothesis that the Pennsylvania law decreased company values and with the hypothesis that the initial market reaction is an unbiased estimate of the law's effect on firm values. 相似文献

In search of the meaning of entrepreneurship 总被引:9,自引:0,他引:9
This paper is an attempt to build a bridge between the popular and the academic usage of the terms entrepreneur and entrepreneurship, and to identify the raw materials needed to construct an interpretive framework capable of illuminating the nature of entrepreneurship and its role in economic theory. We review briefly the contributions made to this topic by Cantillon, Schumpeter, Schultz and Kirzner. We advance a synthetic definition of the entrepreneur as someone who specializes in taking responsibility for and making judgemental decisions that affect the location, the form, and the use of goods, resources, or institutions. We then conclude with some observations on the basic choice confronting economics regarding the place of entrepreneurship in economic analysis. 相似文献

Modern professionals are engaged in making things better, but the specific advances on the micro-level are increasingly undercut by problems on the macro-level. The content of this better is typically guided by values such as efficiency, productivity or cost-effectiveness, which are essentially output over input ratios unable to account for how a specific improvement will fit into the broader human, social and ecological contexts. Hence, micro-level advances lead to fragmentation and a loss of harmony, compatibility and conviviality. The situation is further complicated by the fact that, culturally speaking, science and technology have become good in themselves, making reasonable discourse difficult. This paper concludes with an analogy from an earlier epoch suggesting how the situation may be resolved.
