In a developing profession, emphasis is placed on two key ingredients for a successful climb to the executive suite — namely, interpersonal skills and an appropriate personality structure than can cope with forms of stress and uncertainty. The data presented in this study were collected from one of the major accounting firms and offers insights into men and women on the upward climb within the accounting profession. Analysis of this data shows that although appropriate personality characteristics are predicated on a male managerial model, women and men perceive themselves similarly with respect to these characteristics. However, others' perceptions of women, male accountants as well as clients, seemed more skeptical of women's ability to succeed. Furthermore, there are indications that women and men have different job assignments along their career paths. Our data collected in the latter half of the seventies tend to corroborate many of the findings in the first half — in general women are not perceived as ready for the managerial climb.  相似文献

The AICPA and NYSE urge corporations to avoid the term “stock dividend” and use the term “stock split” when referring to large common stock distributions. Theoretically these large distributions do not convey any economic value to the stockholders. Therefore a rule was considered necessary so as not to mislead them as to the actual nature of the distributions. The purpose of this study is to examine security price reactions to the differential naming of these distributions. The results strongly suggest that security returns are not differentially affected by naming a large common stock distribution a stock dividend rather than a stock split. That is, the capital market appears to be semantically efficient between terminologies.  相似文献

This paper analyzes the money stock effects of the Monetary Control Act (MCA) under a nonborrowed reserve (NBR) operating procedure. Prior to the passage of the MCA, policy was conducted under an interest rate operating target where reserve requirement reforms such as those introduced by the MCA had little influence on money stock variability. Under an NBR procedure however, the structure of reserve requirements may have a significant impact on monetary control. Our analysis indicates that the relative improvement in monetary control greatly depends on the degree of tightness exercised by the Federal Reserve over total reserves in an MCA regime. The tighter the control, the more significant the estimated monetary control benefits of the MCA under an NBR procedure.  相似文献

In the pharmaceutical area, third world countries have been particularly subjected to excessive pricing and manipulative marketing practices by multinational corporations. Sri Lanka has gained some experience in curbing abuses by establishing a State Pharmaceuticals Corporation. It has been able to achieve substantial price cuts for pharmaceuticals and to adapt to changing economic and political circumstances. The control of advertising and marketing practices remains a problem but has been tackled in Sri Lanka by an Act of 1980. Until similar laws are enacted greater attention should be given to the individual patient by doctors becoming more circumspect in prescribing drugs.
Strategien der Länder der Dritten Welt zur Regulierung des Vertriebs und der Werbung von Arzneimitteln
Zusammenfassung Länder der Dritten Welt sind für multinationale Unternehmen auf dem Arzneimittelsektor ein bevorzugtes Objekt für Ausbeutung durch überhöhte Preise oder manipulatives Marketing. Der Autor, mit diesen Problemen an leitender Stelle persönlich vertraut, beschreibt Versuche in Sri Lanka, Mißbräuche ausländischer Unternehmen durch Errichtung einer staatlichen pharmazeutischen Gesellschaft (State Pharmaceuticals Corporation) zu bekämpfen.Das Unternehmen hat wesentliche Preisreduzierungen für Arzneimittel erreicht und sich an geänderte wirtschaftliche und politische Verhältnisse anpassen können. Werbung und Vertriebsmethoden werden neuerdings in Sri Lanka — wie in anderen Ländern der Dritten Welt — durch ein Gesetz von 1980 kontrolliert, das allerdings für homöopathische und ähnliche Produkte nicht gilt. In der Zukunft kommt es darauf an, den individuellen Patienten durch eine vorsichtigere Verschreibung von Arzneimitteln mehr Aufmerksamkeit zu widmen.

As part of an investigation into the performance of heating systems and the effectiveness of energy saving measures, temperatures have been monitored in forty centrally heated homes. The addition of extra insulation had no effect on the way people operated their heating system or on the temperature level set in the main living room. However, bedrooms were warmer and the importance of individual room temperature controls demonstrated. Differences between people's thermal requirements in domestic and office environments are considered.  相似文献

Risk is an important characteristic of decisions about weed control in crops. In this paper it is shown that risk can affect weed control decisions even if the objective of the decision maker is to maximise expected profits: that is, even if the decision maker is ‘risk-neutral’ in the usual economic sense. This is shown for two decision frameworks: the optimal rate approach and the economic threshold approach. Empirical results are presented for control of ryegrass in wheat in Western Australia. It is found that, in general, risk reduces the optimal level of herbicide use under expected profit maximisation. Although individual sources of risk have a small impact on the optimal decision rules, combinations of uncertain variables can have a relatively large effect.  相似文献

This note comments on the econometric analysis of the dynamic relationship between agricultural research expenditures and agricultural productivity change. The validity of the Almon restrictions, particularly endpoint restrictions, commonly imposed on the distributed lag is questioned. It is suggested that models incorporating such restrictions may lead to biased estimates of the effects of research spending. More fundamentally, doubts are raised as to whether any meaningful relationship between research spending and productivity change can be established from the available data.  相似文献

Summary This article presents a survey of recent literature on stock market efficiency, with special reference to the US and Dutch stock markets. Additionally, models are specified and estimated for the daily return since 1987 on FTA indices for eleven major stock markets, allowing for non-normality, heteroskedasticity, leverage effects and autocorrelation. The leverage effect and positive autocorrelation are characteristics of some of the indices investigated. The magnitude of the autocorrelation, however, is so small, that no profitable arbitrage opportunities arise and weak-form efficiency of these stock markets is not rejected.  相似文献

Structural changes in U.S. agriculture, influenced by technological and institutional forces, have altered the economic and social characteristics of rural America, especially that segment of rural America populated by farmers and their families. Changes in the structure of agriculture have greater implications for small scale farmers, many of whom are African American, in that strategic options for their farm-firms are constrained to: increasing their farm size, exiting farming, and obtaining off-farm employment to survive. This article presents a rationale for public support of limited resource farmers, identifies structural trends in U.S. agriculture and their impacts on African American farmers, discusses economic problems unique to these farmers, and recommends needs for specific public policies and development programs.  相似文献

Summary The voluntary saving rate has declined in The Netherlands over the last thirty years. In this paper the increasing share of transfer income in total income, with a high propensity to consume, and the increase in collective pension schemes are simultaneously used to explain this development. Furthermore, the influence of taxes is modelled. The planning horizon of the representative consumer is treated as a parameter to be estimated. The planning horizon obtained (about 4.5 years) appears to be short compared to expected residual lifetime, implying rather small interest elasticities. The estimation results indicate that, in case the obligatory pension schemes are diminished, the representative consumer offsets the loss in pension benefits for 75 per cent by voluntary, additional accumulation of nonhuman wealth in the long run. The working of the model is illustrated by simulation experiments.I wish to thank two anonymous referees, Prof. J. Pen, G.M.M. Gelauff, J.J. Graafland, W. Vossers and other colleagues of the CPB for their helpful comments.  相似文献
