Using a highly portable computer to gather qualitative social network data

We report on the use of a highly portable computer for collecting precise and accurate data concerning specific social network ties. Our experience confirmed that a highly portable computer, when loaded with a flexible database management program, is a useful tool for such a task. Data entry can be done during the interview and information retrieval can provide immediate and useful information for the respondents. The use of the computer with semistructured interviews changes the dynamics of the interview situation. A three-way interaction is created between the interviewers, the respondents and the information in the database. We found that there were great benefits from having two or three respondents in the session, and that it was desirable to have two interviewers.     

Information in the hiring process: A case study

A variety of theoretical models have been concerned with the extent to which economic agents base their decisions on full information. This paper describes the stages of the hiring process for secretaries in a large conglomerate, the information sources used at each stage, and then estimates the relative importance of each source. Almost all applicants are interviewed when they apply and the interviewer's comments are a significant source of information. But in spite of the firm's use of complex information, it appears that the people hired are not likely to do well than those applicants not hired.     

Leveling the Playing Field for Women of Color in Corporate Management: Is the Business Case Enough?

A study was conducted in order to examine the unique experiences of African-American, Hispanic, and Asian-American women in business careers. A multi-phase research design included: a survey of professional and managerial women of color in 30 companies with 1735 survey responses; an analysis of national census data; qualitative analyses from 59 focus groups and 83 individual interviews; and diversity policy analyses at 15 companies. The study found that retention of women of color was positively correlated with supportive behaviors of supervisors. The authors argue that the financial business case for diversity, e.g., the cost of turnover, is necessary but not sufficient for developing and sustaining supportive relationships between supervisors and their women of color direct reports.     

Effects of recontracting on shareholder wealth: The case of voluntary spin-offs

This paper investigates the effect of voluntary corporate spin-off announcements on shareholder wealth. A significant positive share price reaction is documented for 93 voluntary spin-off announcements between 1963 and 1981. These shareholder gains do not appear to come wholly at the expense of bondholders. Evidence suggests the gains to shareholders may arise from tax and regulatory advantages and/or improved managerial efficiency resulting from the spin-off.     

Customer-centered brand management

Most executives today agree that their efforts should be focused on growing the lifetime value of their customers. Yet few companies have come to terms with the implications of that idea for their marketing management. Oldsmobile, for example, enjoyed outstanding brand equity with many customers through the 1980s. But as the century wore further on, the people who loved the Olds got downright old. So why did General Motors spend so many years and so much money trying to reposition and refurbish the tired,tarnished brand? Why didn't GM managers instead move younger buyers along a path of less resistance, toward another of the brands in GM's stable--or even launch a wholly new brand geared to their tastes? Catering to new customers, even at the expense of the brand, would surely have been the path to profits. The reason, argue the authors, is that in large consumer-goods companies like General Motors, brands are the raison d'etre. They are the focus of decision making and the basis of accountability. But this overwhelming focus on growing brand equity is inconsistent with the goal of growing customer equity. Drawing on a wide range of current examples, the authors offer seven tactics that will put brands in the service of growing customer equity. These include replacing traditional brand managers with a new position--the customer segment manager; targeting brands to as narrow an audience as possible; developing the capability and the mind-set to hand off customers from one brand to another within the company; and changing the way brand equity is measured by basing calculations on individual, rather than average, customer data.     

Estimating the Economic Benefits of Cleaning Up Superfund Sites: The Case of Woburn,Massachusetts

Superfund was established in 1980 to deal with closed and abandoned hazardous waste sites. Given the large amounts of money being spent on cleanups of Superfund sites, one might hope that the money is being spent in a cost-effective manner, but there is little evidence that the estimated benefits from cleanup affect the cleanup decision. We apply the hedonic method to house prices to estimate the individual willingness to pay (WTP) to clean up a Superfund site. We then show how the individual WTP can be used to calculate the total benefits from cleaning up the site so that a cost-benefit analysis of Superfund cleanup can be undertaken. We apply our technique to the two Superfund sites in Woburn, Massachusetts. We find that the benefits from cleaning up these sites are in the range of $72 million to $122 million (1992 dollars). It is likely that these benefits are greater than the present value of the estimated costs of cleaning up these sites. Thus it appears that the cleanup of the Woburn Superfund sites results in positive net benefits to society.     

Implications of Web assurance services on e-commerce

The ongoing rapid growth in the popularity of the Internet is having a revolutionary impact on the way companies do business. Doing business online has become a necessity, not an option. However, some consumers are not completely comfortable using the Internet for transacting business because of concerns regarding security of their transactions. For these situations, consumer trust and confidence can be enhanced by a Web assurance service such as AICPA Trust Services. Building on prior studies, the study provides comprehensive information on current reporting requirements, differences among Web assurance services, and results of a recent consumer survey to obtain perceptions of Web assurance services. The theoretical foundation of the current study is based on the Assurance Gaps Model [Burke, K. G., Kovar, S. E., & Prenshaw, P. J. (2004). Unraveling the Expectations Gap: An Assurance Gaps Model and illustrative application. Advances in Accounting Behavioral Research, 7, 169–193]. E-business consumers (users of Web assurance services) can be dichotomized into older consumers and younger consumers, who have different expectations based on information asymmetries. Findings indicate that consumers value Web Assurance services, but younger consumers place greater value on these services than older consumers.

Measuring risk in the mining sector with ARCH models with important observations on sample size

This paper uses the GARCH technique to estimate time-varying individual firm risk measures for the mining sector. In general, the mining industry is riskier than the market with estimated betas greater than one. The results also show that the level of risk in the industry is quite volatile and can be divided into three distinct time periods according to the magnitude and variability of the firm's betas. Additionally, the number of observations in a sample has a strong relationship to the detection and estimation of an ARCH effect in the data, which cannot be explained by firm financial size.
