Relatively high estimates of the welfare cost of monopoly power in U.S. manufacturing industries have been obtained by economists who use the Lerner equation to estimate this welfare cost from profit data. These Lerner equation loss estimates are appropriate for a monopoly with constant costs and linear demand. But if the industry is an oligopoly in a Nash-Cournot equilibrium, the Lerner equation loss estimates can be more than twice as large as the actual welfare gain that would result from the elimination of monopoly power. Partial and general equilibrium examples are presented to illustrate the nature of these estimation errors.  相似文献

Since the development of the capital asset pricing model, a number of studies have examined the effect of a firm's operating leverage on its systematic risk. The essential conclusion of these studies is that operating leverage affects systematic risk through either the contribution margin or unit variable costs. In this paper, the models derived in previous research are refined and extended to demonstrate that, for either a single-product or multiproduct firm, the degree of operating leverage measures the full effect of a firm's operating leverage on its systematic risk. In addition, it is shown that a sales variability measure should also be an important differentiating factor among the systematic risk of common stocks. Thus, the results have important practical implications for financial managers when estimating project or divisional risk for investment decisions, and for security analysts when predicting the systematic risk of common stocks.  相似文献

In this article, the multidimensionality of price as perceived by members of a consumer panel is examined. Respondents are first classified as price-sensitive or non-price-sensitive with respect to a durable and a nondurable product. Several dimensions of price are then described within the framework of brand purchase decision situations, and consumer evaluations of the importance of each situational dimension are measured. Dimensions perceived as important by price-sensitive persons are different from those considered important by non-price-sensitive consumers. Variations exist in the importance of price dimensions based on type of product.  相似文献

Managers, theorists, and researchers are interested in studying organizational phenomena such as technological change, organizational development, and leadership effectiveness over a period of time. However, a review of the literature in the field of organizational behavior and management indicates that a limited number of empirically based studies rigorously investigate changes within organizations. This article looks at the salient characteristics and issues facing those engaged in longitudinal research. While much more theoretical and methodological work is needed to improve the rigor of this type of research, some researchers have forged ahead and have attempted to conduct longitudinal research in field settings. A select few of these studies are presented to illustrate what can be accomplished by longitudinal research and what needs to be improved in such research designs. In conclusion, the authors offer some suggestions that may serve to increase the number of longitudinal organizational research studies in the future.  相似文献

A two-stage Delphi research study was undertaken to determine and measure the attitudes of the public regarding factors that may either inhibit or stimulate solar energy commercialization today and over the next 10 years. Some factors judged important were product cost, lack of product knowledge, lack of governmental support, and public concern over the energy crisis. The factors were determined by a group of energy conscious respondents who completed the Delphi research. They also indicated the likely and desirable actions to be taken by government and business. These included more funding of research and development, tax incentives, increased public education, and reduced prices. The Delphi research proved to be an effective method for investigating solar energy commercialization, as the attitudes expressed in the second survey converged with those identified during the first stage. Furthermore, governmental and business actions suggested in the study could help to initiate greater solar energy use and developmental efforts.  相似文献

This paper examines the proposition that local nationals employed as (local) managers by foreign subsidiaries of multinational corporations have managerial attitutes which are generally between those of indigenous managers employed by domestic firms in both the parent and host countries. The evidence strongly suggests that the concept has validity, and that the organization attributes of capital, R&D, and marketing intensity influence the managerial attitudes of the three groups of managers and the differences among these attitudes.  相似文献

The purpose of this study is to examine empirically whether managerial pay of small-firm executives is more closely related to profitability or generation of sales. Conventional economic doctrine supports the hypothesis that chief executives are paid primarily to advance profitability. The contrary hypothesis, given impetus by Baumol [2] and Galbraith [8], asserts a closer relationship between compensation and sales. Previous studies of large corporations have produced conflicting results. Regression analysis of the 78 small firms in this study reveals managers receiving compensation correlating fairly closely with both profitability and sales. The cumulative forces at work in these firms impacting upon managerial pay appear to have wrought a linkage conductive toward motivating managers to be both “bottom line” and marketing oriented.  相似文献

Unproven assertions about potential option returns have accompanied increased interest in option trading since formation of the CBOE. This paper presents an analysis of return distributions from buying and selling CBOE options. Generally, buying options resulted in returns that were negative and lower than returns from buying the underlying stocks. Average returns from writing covered options exceeded returns from buying both options and stocks. Commissions and taxes shifted location of return distributions for all three investments, particularly reducing returns from buying options.  相似文献

Data collected from field research using structured observations indicate for task communications significant relationships between organization technology certainty (using Perrow's typology) and use of verbal and sign media and no significant relationship with use of object and written media. These data also indicate relationships between technology certainty and stimulus and problem solving communications purposes. Directionality of communications moderates these technology-purpose relationships, even exposing some additional relationships. The last section of this article proposes a reconceptualized model of organization communications, considering technology certainty, member mobility, and leadership style as independent variables and directionality as a moderating variable.  相似文献

There are increasingly sales opportunities for capital equipment in developing countries. Concomitantly, concern is that capital intensive technologies are too widely employed. Yet there has been little reported empirical research on why LDC manufacturers choose specific equipment. Textile manufacturers accounting for a significant part of Peru's spinning and weaving capacities participated in this study by providing perceptions of two capital versus labor intensive technologies capable of producing identical output. Exporters and nonexporters scores, using a five-point scale, were compared by t tests on 19 equipment attributes selected from innovation diffusion studies. Factor analysis determined innovations underlying dimensions. Factor scores were regressed on export commitment proxies. Higher export dependence related to more concern with ease of altering output specifications and less concern with cost, thus supporting that dependence on foreign versus domestic markets will affect equipment decisions. The method of comparing product attribute perceptions provides a simple possibility for segmenting LDC capital equipment markets.  相似文献

For nearly a decade flood insurance was provided by a unique partnership arrangement involving the federal government and the private insurance industry. This study examines (1) the rationale for establishing subsidized flood insurance in the United States, (2) the government-industry partnership formed to provide flood insurance, (3) the reasons why the partnership failed, and (4) the implications of the failure for future joint ventures between government and industry.  相似文献

A generalized expression of the net advantage of leasing (NAL) is used to assess the implications of discounting incremental cash flows at the firm's before-tax cost of debt and the firm's after-tax cost of debt, respectively. If no personal tax biases are assumed, then the before-tax cost of debt should be used to compute NAL. If the before-tax cost of debt is the correct discount rate, then any change in the firm's borrowing level brought about by the decision to lease rather than purchase will alter the computed NAL by the amount of the present value of the tax savings on interest payments. Thus using the before-tax cost of debt is consistent with basic MM valuation theory. Using the after-tax cost of debt, in contrast, implies that any associated change in the firm's borrowing level is irrelevant for purposes of computing NAL. Sufficient conditions are specified for the after-tax cost of the debt to be the correct discount rate for lease versus purchase analysis. Finally, lease analysis in a MM world is compared to lease analysis in a Miller tax world. For the special case of a 100% leverage ratio, the specification of NAL is the same in both worlds. Use of the after-tax cost of debt is correct in a Miller world and is a good approximation in an MM world provided the cash flows are predominantly debt financed.  相似文献

Marketers are vitally interested in the relationships between personal attributes and consumer behavior. This study was developed to examine, using canonical analysis, the relationships of personality and socioeconomic data with innovative behavior of housewives. The Gordon Personal Profile and Inventory provided the personality variables, and socioeconomic variables used were age, marital status, income, and number of children living at home. All respondents were women who represented middle-class housewives in the Columbia, South Carolina, metropolitan area. An initial sample was used to scale a list of products as to their degree of innovativeness in their effect on consumption and usage patterns. A sample of 152 middle-class housewives were then contacted and 142 of these supplied completed questionnaires suitable for analysis. A great many combinations of innovative products and personality and socioeconomic variables were run. Several strong relationships were found. The major ones were between products and socioeconomic variables. However, one analysis showed the most significant levels of association with the innovative products when personality variables were used alone. A brief analysis of the major canonical root for this analysis indicates a woman who uses more malt liquor and club cocktails and who has a microwave oven. Associated with these innovative products are the personality variables of ascendancy, slightly irresponsible, less cautious, and highly sociable. This interpretation might indicate the profile of a woman who is on the way up and likes to socialize without regard to what others think. Many other interesting profiles are also described. The study is exploratory in nature but provides stimulus for additional research and also provides support for previous consumer behavior findings.  相似文献

The corporate boardroom, once an inner sanctum where the secret ritual of top-level policymaking takes place, is slowly opening its doors and letting in a bit of sunshine. As the investing public begins to peer into the corporate “kiva,” it will want to know more about board structure and performance. In anticipation, this study provides an assessment model to correlate 15 boardroom attributes, or directorate dimensions, with company performance. As a major conclusion, the study finds that as yet there is no substitute for technical experience and internal managerial expertise. Neither is there an optimal formula. No two firms have identical boardroom dimensions. As the newer dimensions begin to make contributions, this diversity will be even greater. This accentuates the need for more precise measurement of board structure and effectiveness.  相似文献

Reactions of consumers to marketplace problems vary widely despite the frequent similarity of sources of dissatisfaction. The results of two studies designed to investigate the determinants of consumer inclinations to complain are presented. Two alternative social-psychological explanations of behavior employing self-monitoring, moral and social norms,and attitudes as predictor variables are examined.  相似文献

The image that current and potential customers have of a retail store affects the magnitude of patronage at that store. In attempting to increase store patronage, management of a retail store must look to people who already are customers, as well as to people who are not current customers. The appropriate strategy depends upon the dimensions used by people in their evaluation of the store. The hypothesis is tested that the strategy used for gaining increased patronage from customers may have to differ from that used to gain patronage from noncustomers.Field survey techniques were used to collect data from 225 adult females. Respondents evaluated three large retail department stores, which were believed to have distinct images in the minds of female shoppers, on the basis of a set of 12 semantic scales that represented various store attributes. Each respondent indicated frequency of shopping at each store. The data were analyzed by two different multiple discriminant analyses. For the customer growth strategy, the semantic scale measures were used to develop a discriminant model for each store to determine which attributes would be the best predictors of shopping frequency. The analysis relevant to the strategy of new customer attraction differed. First, shoppers were classified as loyal to one store on the basis of their rates of shopping at each store. Second, the 36 attribute measurements (12 scales for 3 stores) were factor analyzed, and three factors were extracted. Those attributes which loaded highest on each of the factors for each store were used as predictor variables in the discriminant analysis.The results of this study indicate that different marketing strategies may be required for increasing sales to existing customers and attracting new customers. In addition, consumers do not necessarily differentiate similar type retail stores on the same dimension.  相似文献

A theoretical and empirical examination of the relationship between product class familiarity and usage of information processing strategies is presented. Four major dimensions of information processing strategies are identified and used to conceptualize the linkage between product class familiarity and usage of particular strategies. Research hypotheses are tested in an exploratory study using a laboratory choice situation. Implications of the study with respect to usage of specific strategies and for future research are discussed.  相似文献

The market rate of return and related risk of a group of 23 property-liability insurers are explored. The focus is on the return earned by the stockholders of these firms. Previous studies have only examined the accounting rate of return. This study compares the accounting rate of returns to stockholder yields. Several factors that effect the return earned by shareholders are reviewed.The average return on the property-liability stocks studies was 4.0 percentage points greater than the accounting rate of return (0.14 vs 0.10). This evidence suggests that studies based only on accounting rates of return under-estimate returns earned by property-liability shareholders. On a risk-return basis property-liability profits were found not to be significantly different from the general stock market. However, several individual firms had superior stockholder yields. The beta for the group of firms was 1.09.  相似文献

Are there households in trading areas that have unique mobility predispositions? Can mobility types be monitored? And does mobility type relate to the life style and consumption patterns of households? This study examines the mobility and life style characteristics of suburbanites in a medium-sized city in an effort to discover the answers to these and other questions.In particular, the article suggests that mobility relates to life style and media usage, which in turn largely determines the quality of consumer demand and the most efficient media to reach such a market. If the composition of mobility types within a shopping area is changing, retailers should monitor these changes so that they can better predict retail demand—both quality and quantity.A self-administered questionnaire was designed to measure (1) the mobility characteristics of consumers—including their local moves, long-distance moves, and their predisposition to move; (2) the life styles and socioeconomic characteristics of consumers; and (3) the median exposures of households. The instrument was administered by personal interviews with 322 suburban housewives within a medium-sized trading area. The usage sample included 304 cases.The data support the hypotheses of the study; mobility types emerged from the analysis and these had distinctive life styles and media habits. Periodic sampling of households is suggested as an approach to monitoring mobility composition within the trading area.  相似文献
