A prominent philosophical/legal case for requiring 100% bank reserves employs a flawed style of argument. It involves essentialism
(criticized by Karl Popper and Joseph Schumpeter), persuasive definitions (identified by Charles L. Stevenson), faulty classification,
and the piling up of irrelevant facts and considerations. 相似文献

The Academy of Management formally adopted a Code of Ethical Conduct in 1990. During the subsequent 15 years, almost nothing had been published about it and its value as a formal document meant to guide professional practice. Rather surprisingly then, in December 2005 an entirely new Code of Ethics was introduced by the Academy’s Board, to take effect in February 2006. Why was a new code promulgated? More broadly, what do the contents of these codes, the processes of their promulgation, and their expressed purposes, suggest about the value of such codes for similarly situated professional associations, in general? This article seeks to identify key strengths and weaknesses of the original code, begin an assessment of the potential value of the new code, and so stimulate debate. Further, not only is this a call to the members of the Academy to engage in some thoughtful debate and possible amendment of its new code, but also a caution to all such associations to take seriously the hurdles that must be jumped before any code can be developed and promulgated to worthwhile effect. 相似文献

Abstract The following situation is considered. A fixed number (= n) or sequence of independent trials T 1 T 2,…, T n is given, and in each of these an event E mayor may not occur, It is further observed that the event E occurs a total of k times amongst the n trials T i , (i = l,…, n). It is then required to test the hypothesis H 0 that the probability of the occurrence of E is constant from trial to trial, i.e. H 0 is the hypothesis: p 1 = p 2 = ? = p n = p, if p n (i = 1, …, n) represents the probability that E occurs on the ith trial. 相似文献

Recently, Fair (1987) has addressd an interesting question in the areas of demand for money, namely, whether the adjustment of actual to desired demand for money is in nominal or real terms. His conclusion, based on time-seies analysis for twenty-seven countries, including a few developing countries, was that the evidence was overwhelmingly in favour of the nominal hypothesis. The aim of this paper is to address the same issue for eleven Asian countries. In the process, a reformulation of the test procedure used by Fair is suggested. In addition, the question is also examined within the framework of the error correction model. The models are also tested for structural stability. The scheme of the paper is as follows. The models and the tests are specified in Section I. The data and the estimation issues are dealt with in Section II. Section III presents the results. The paper is concluded with a brief summary of the major findings. 相似文献

Although evidence of a link between socioeconomic status and child health has been researched extensively, much less attention
has been devoted to studying the link between child health and cognitive development. This paper seeks to determine whether
early childhood illnesses and poverty significantly impede cognitive development. The empirical model attempts to control
for observed and unobserved heterogeneity through the use of panel data models. Results indicate that a child’s cognitive
development is not directly related to health problems acquired after birth or socioeconomic standing. Rather, cognitive development
is primarily influenced by unobserved child- and family-specific factors that happen to be correlated with health and socioeconomic
status. On the other hand, birth weight appears to affect cognitive performance later in childhood, even after taking unobserved
heterogeneity into account. 相似文献

Hedge funds often impose lockups and notice periods to limit the ability of investors to withdraw capital. We model the investor's decision to withdraw capital as a real option and treat lockups and notice periods as exercise restrictions. Our methodology incorporates time-varying probabilities of hedge fund failure and optimal early exercise. We estimate a two-year lockup with a three-month notice period costs approximately 1% of the initial investment for an investor with constant relative risk aversion utility and risk aversion of three. The cost of illiquidity can easily exceed 10% if the hedge fund manager can arbitrarily suspend withdrawals. 相似文献

There is a compelling need to improve the relationship between managers in marketing and sales departments. This paper argues
that one critical way of enhancing individual managers’ perceptions of relationship effectiveness between these departments
is to view the issue as a matter of justice and suggests that perceived marketing–sales relationship effectiveness is positively
influenced by managers’ perceptions of organizational justice. Furthermore, it proposes that interfunctional communication
has the potential to enhance the proposed positive effects of justice and hence needs to be considered and effectively managed
when looking at marketing–sales relationship effectiveness. Data drawn from a survey of 203 marketing and sales managers in
38 consumer packaged goods companies are used to empirically test these predictions. The authors find that perceived sales–marketing
relationship effectiveness is influenced by perceptions of distributive, procedural and interactional justice. Greater interfunctional
communication is found to further enhance the positive effects of distributive and procedural justice on perceived relationship
effectiveness, but it does not contribute to the already strong positive effects of interactional justice. Furthermore, results
reveal important differences in the effects of justice on perceived relationship effectiveness across the marketing and sales
departments. 相似文献

When estimating finance panel regressions, it is common practice to adjust standard errors for correlation either across firms or across time. These procedures are valid only if the residuals are correlated either across time or across firms, but not across both. This paper shows that it is very easy to calculate standard errors that are robust to simultaneous correlation along two dimensions, such as firms and time. The covariance estimator is equal to the estimator that clusters by firm, plus the estimator that clusters by time, minus the usual heteroskedasticity-robust ordinary least squares (OLS) covariance matrix. Any statistical package with a clustering command can be used to easily calculate these standard errors. 相似文献
