When the firm is uncertain about the efficiency units of labor that it employs, some organizational forms—franchise, owner-operated, and multiplant firms— may be more profitable than others. As a result, particular organizational forms may dominate an industry with uncertain inputs. Conversely, various organizational forms may be selected by a company selecting producing units that will maximize the decision maker's expected utility of profits. This paper offers an alternative view of firm attributes associated with x-efficiency.  相似文献

A translog cost function is estimated for U.S. manufacturing in order to investigate plant size differences in responses to increases in energy prices. Smaller plants were more intensive users of energy in the early 1970s but were also better able to substitute out of energy and into other inputs during the first round of energy price increases. As a result, by the mid-1970s larger plants had become more intensive energy users. Thus, later energy price increases probably had a greater adverse impact on the production costs of larger plants in manufacturing.  相似文献

This study shows how scale economies, initial size differences among firms, potential competition, and adjustment costs may influence the entry of firms into a dynamic oligopoly. It also examines the effects of these factors on the final size distribution of firms in an industry, and on the welfare levels of consumers and producers. We find that low to moderate scale economies are insufficient for Cournot-Nash competition to drive small firms from the market. Only when scale economies are quite high will the distribution of firm sizes become degenerate. Potential competition and the size of incumbent firms' capital stocks are additional barriers to entry. The welfare conclusion is that there may be a government role to preserve potential competition, but also to dissuade small firms from entering certain markets where there are economies of scale.  相似文献

The impressive growth in countertrade necessitates a careful look at this trade financing mechanism and a new attitude by American policy makers and businessmen toward it. This study looks at the various forms of countertrade, at the motivating forces behind it, at the pitfalls that countertrade could engender, and at some imperatives in the negotiation of countertrade deals. The issues are examined from the perspective of a policy maker and that of a businessman. The two perspective are distinct but overlap sufficiently to merit a joint examination. It is the conclusion of this study that countertrade is here to stay, and that American businessmen better learn to cope with it if they are to maintain and improve their competitiveness in the world markets.  相似文献

This paper examines the efficiency with which the Australian share market incorporates new information relating to interest rates and the monetary aggregates into share prices. It finds a strong relationship between medium term government security yields and equity returns although little relationship could be found between unanticipated changes in the monetary aggregates and share returns. Furthermore, the interest rate relationship involved long lags and suggests inefficiency in stock market pricing in Australia.  相似文献

BESSEL PROCESSES, ASIAN OPTIONS, AND PERPETUITIES   总被引:11,自引:0,他引:11  
Using Bessel processes, one can solve several open problems involving the integral of an exponential of Brownian motion. This point will be illustrated with three examples. The first one is a formula for the Laplace transform of an Asian option which is "out of the money." The second example concerns volatility misspecification in portfolio insurance strategies, when the stochastic volatility is represented by the Hull and White model. The third one is the valuation of perpetuities or annuities under stochastic interest rates within the Cox-Ingersoll-Ross framework. Moreover, without using time changes or Bessel processes, but only simple probabilistic methods, we obtain further results about Asian options: the computation of the moments of all orders of an arithmetic average of geometric Brownian motion; the property that, in contrast with most of what has been written so far, the Asian option may be more expensive than the standard option (e.g., options on currencies or oil spreads); and a simple, closed-form expression of the Asian option price when the option is "in the money," thereby illuminating the impact on the Asian option price of the revealed underlying asset price as time goes by. This formula has an interesting resemblance with the Black-Scholes formula, even though the comparison cannot be carried too far.  相似文献

This article shows that serious analytical errors may occur in expected utility theory when Taylor series approximation methods are used without careful attention to underlying mathematical assumptions. Recent studies have developed theory incorporating skewness of return into expected utility calculations based on a Taylor series approximation. It is apparent that this theory is invalid if assumptions for application of a Taylor series cannot be met. Errors may occur if returns fall outside the region of convergence of the utility function ot if the partial sums of the Taylor series provide poor approximations to the utility function. Stylized examples are presented to illustrate miscalculation of utility when the various assumptions are violated. These examples are motivated by the use of Taylor series approximations in current literature which deal with the new spectrum of financial securities.  相似文献

The primary objective of this article is to present a social comparison model of how employees perceive, evaluate, and react to tasks. The model represents a synthesis of recent findings in the task design area and three social comparison theories. A three-stage process is described which suggests that employees first understand their tasks at an informational level, then understand their tasks at an evaluative level, and finally react to their tasks both affectively and behaviorally. Managerial implications and future research directions are discussed.  相似文献

Considerable confusion surrounds the role of importance in multiattribute attitude models. The present study tests a theoretical proposition as to how attribute importance is manifested in the expectancy-value formulation. Though not unequivocal, the results suggest that order of elicitation may be more valid than structured ratings as an indicant of attribute importance.  相似文献

Boundary-spanning activity and its effects on role conflict and ambiguity and job satisfaction were studied in a large manufacturing organization. Longitudinal data were collected 11 months apart from 132 managerial, engineering, and supervisory employees. A corrected cross-lagged correlational analysis suggests no casual relationships between boundary-spanning activity and role conflict and ambiguity. Causal, positive relationships are suggested, however, between boundary-spanning activity and satisfaction with work, promotions, supervision, co-workers, and overall job satisfaction.  相似文献

This study uses the public announcement of an advance refunding to examine the informational efficiency of the secondary market for municipal bonds. The data show that bond yields respond quickly and in the direction predicted. The text discusses methodological considerations and the data sources used in the tests. The results of the study indicate that even for infrequently traded bonds, yields can be expected to reflect fully changes in default risk.  相似文献

This paper has attempted to isolate that portion of the underground economy which is both measurable and controllable. The standard variables postulated by Cagan, income and interest rates, are still important, although the value of the income elasticity of currency demand may be larger than expected. Marginal tax rates have a positive and significant influence on currency holdings, which supports Tanzi's work and contradicts the findings of the Internal Revenue Service. While not all the increase in currency holdings in the last 20 years can be explained by using tax rates, somewhere between $11 and $12 billion worth of currency can be attributed to that source. While unemployment compensation ought to affect the size of the underground economy, no statistical verification can be found through the specification contained here. Finally, it is noted that the trend toward less currency holding, which one would expect from the recent banking innovations, would have occurred had not other forces offset it.One of the forces which has probably led to an increase in currency holdings is increased drug-related activity. However, that portion of the underground economy which exists because of crime has been largely ignored here because little of it can be controlled by economic policy. What is explored here is a measurement of how much underground activity we could dissuade by lowering taxes, and further, how those lower taxes would influence tax collections. The effects appear to be large enough to warrant concern about the impact of tax rates on incentives.  相似文献

The marketing literature has overlooked the problem of designing optimal organizational structures for marketing management. The study of this problem is crucial and pressing. Some relationships are proposed between the information generated by the market environment and the ability of the organization of a marketing department to process this information. Insights and opportunities for future conceptual and empirical work are provided.  相似文献

Of recent time, there has been a proliferation of concerns with ethical leadership within corporate business not least because of the numerous scandals at Enron, Worldcom, Parmalat, and two major Irish banks – Allied Irish Bank (AIB) and National Irish Bank (NIB). These have not only threatened the position of many senior corporate managers but also the financial survival of some of the companies over which they preside. Some authors have attributed these scandals to the pre-eminence of a focus on increasing shareholder value in Western business schools and/or to their failure to inculcate ethical standards. In this paper, we challenge these accounts and the aetiological view of knowledge from which they derive but are grateful for the consensus that they convey regarding the importance of business ethics. The paper focuses on different approaches to ethical leadership concluding with a view that some hybrid of MacIntyre’s virtue ethics and Levinas’s ethics of responsibility may serve as an inspiration for both educators and practitioners.
