Coefficient of determination in a simultaneous equation model: A pedagogic note

The simultaneity of the market for securities has been recognized by a number of finance authors. Simkowitz and Jones [10] advocate the use of a simultaneous equation system to capture some of the relationships among the securities in a homogeneous set. Simkowitz and Logue [11], and Jones and Simkowitz [6], have performed studies using a simultaneous equation system in a capital asset pricing framework. Marcis and Smith [9] call for the use of the simultaneous methodology when there is a strong residual correlation between securities. Simultaneous equation systems have been used in other areas of finance by authors such as Barnea [1], Herbst [5], and Logue and Lindvall [8]. This note explores how anomalies concerning the coefficient of determination (R²) mentioned in previous research could have occured. Conditions under which the (R²) does not have its usual properties and an example is given.     

Does source affect response to direct advocacy print advertisements?

This posttest-only experiment examined how source attribution and the personality characteristic of fatalism affect evaluate and behavioral intention responses to direct advocacy print advertisements. Two commercial sources, a noncommercial source, and no source were manipulated in an identical print advocacy ad. Regression analysis revealed that subjects exposed to the two commercial source treatments evaluated the ad more negatively than subjects exposed to the noncommercial and no source treatments. The commercial and trade association source treatments also produced a negative intent to respond to the advocated request. Fatalism was found to be significantly related to behavioral intention, but not the message evaluation. Overall, the results indicate that commercial sponsors should employ direct advocacy print advertisements with the knowledge that their commercial identification elicits critical and negative responses from uncommitted audience members.     

Product familiarity and information processing strategies: An exploratory investigation

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.     

Operating leverage as a determinant of systematic risk

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.     

Retailing strategy for customer growth and new customer attraction

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.     

Longitudinal organizational research in field settings

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.     

Mapping market mobility: Psychographic profiles and media exposure

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.     

Reliability and cross-validity of trade-off analysis in an industrial setting

More than 200 applications of trade-off analysis now have been completed. A review of the literature uncovers only four sources that evaluate the reliability or validity, or both, of trade-off analysis using the concept evaluation approach. Detailed evaluations of trade-off analysis based on trade-off grid data are unavailable. This paper reports reliability and cross-validity experience using this approach.     

Accuracy of management and security analysts' forecasts: Additional evidence

This paper provides further support for findings in studies by Basi, Carey, and Twark [2] and Ruland [5] which indicated no statistically significant superiority of management over analysts in forecasting earnings per share. These somewhat surprising findings are seen to flow from several possible sources. Lack of superior management forecasting performance may reflect (1) a considerable sharing of the forecast or forecast-related information by management with analysts, or (2) firm-specific data (to which management is more privy) may be less important in forecasting performance than data on economy-wide movements.     

Corporate governance: Assessing corporate performance by boardroom attributes

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.     

Speeding solar energy commercialization: A Delphi research of marketplace factors

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.     

Managerial pay and financial performance of small business

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.     

Perceived industrial innovation advantage and export commitment

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.     

Demographics in consumer behavior

Four criticisms against using socioeconomic and demographic (SED) factors in consumer behavior are reviewed: dissatisfaction with models of consumption behavior developed by economists and sociologists, obsolescence of SED factors in mass consumption societies, poor predictions produced by SED factors, and a grass-is-greener attitude held by consumer researchers. The insights offered substantially hurt the validity of these criticisms. Strategies for better theory and research in consumer behavior using SED factors are described.     

Perceived situational effects on price sensitivity

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.     

Bargaining in distribution channels

This study empirically assesses the impact two fundamental dimensions of distribution channels have on channel member bargaining behavior, namely, (1) the expected duration of the channel bargaining relationship and (2) the channel member dependence on the bargaining. The following findings were observed from a laboratory study using 160 business students: low dependence produced fewer bargaining sessions ending in agreement compared to high dependence among buyer-seller dyads. Low dependence bargainers made more extreme initial offers, conceded less, and used the pronoun we less than did high dependence bargainers. The sellers emerged better off than the buyers from the negotiations. Sellers achieved this advantage by making more extreme initial offers than buyers, conceding more than buyers, but emerging with the better deal.
