The Relevance of the Fishbein Model to Insurance Buying

Consumer decision making is a much-researched area. This cannot be said of the more specific area of the insurance purchaser. This study explores the validity to insurance of Fishbein's ‘Theory of Reasoned Action’ model and examines the responses obtained in the elicitation stage, the first stage in the model's two-stage process. The authors consider some of the implications arising from the salient and normative beliefs extracted.     

Commerce with a conscience: corporate control and academic investment

Corporations have been investing in academia to an extent that could be classified as a corporate takeover of universities. Intra‐university critics see this as an ethical problem, because of the degree of business control over university policies and decisions which accompanies the funding. University critics rarely suggest that the corporate funding be given up, returned, or even limited. What they protest against is corporate control, which they see as threatening university autonomy, and as inimical to the public good. Multi‐university conferences have been held focusing on this problem, and the most serious solution proposed thus far is to construct a relevant code of ethics regulating and limiting corporate involvement, through standards and guidelines which corporations will then have to subscribe to, in order to fund universities. However, there is a conflict of interest here. Universities have a public trust and a fiduciary duty not to compromise education. This implies a covenant not to cede power to outside interests, not to use university resources, or faculty and students, as a means to an educationally irrelevant end. Universities cannot sell out. However, it seems equally dishonest not to offer their students a well‐funded first‐rate, quality education in applied fields with current skills, maximum research opportunity, and the corporate ties that would allow them to obtain jobs. We examine three cases showing errors made by universities in ceding control to corporate investment, and draw some policy conclusions.     

Estimating the Impact of Anti-dumping and Anti-cartel Actions Using Intervention Analysis

Intervention analysis is proposed as a method for estimating the effects of anti-dumping actions in the presence of a domestic cartel. Data requirements and modelling effort compare favourably with traditional structural model approaches. The method is applied to an anti-dumping action brought to the European Commission and in which the European producers of the product were fined after an anti-cartel action by the Commission covering an overlapping period. Interven tion analysis is applied to distinguish the effects of the anti-dumping action from those of changes in cartel behaviour     

Marketing in five “simple” questions!

Peters (1987) describes how after some of his seminars he is asked “But what do I DO?”. This question is also often directed at people who have been introducing marketing ideas to businessmen—particularly businessmen whose work does not bring them into contact with customers. This article explains how anybody can start to think in marketing terms by asking five simple questions about the organisation they work for. “Simple” to ask, but requiring disciplined thought if answers are to be found which lead to appropriate managerial actions. “Difficult” to answer not least because the answers to each question affect the answers given to the others. In doing so it also introduces a number of basic but important marketing concepts.     

Evaluating wind-following and ecosystem services for hydroelectric dams in PJM

Hydropower can provide inexpensive, flexible fill-in power to compensate for intermittent renewable generation. Policies for hydropower dams maintain multiple services beyond electric generation, including environmental protection, flood control and recreation. We model the decision of a hydroelectric generator to shift some of its power production capacity away from the day-ahead energy market into a “wind-following” service to smooth the intermittent production of wind turbines. Offering such a service imposes both private and social opportunity costs. Since fluctuations in wind energy output are not perfectly correlated with day-ahead energy prices, a wind-following service will necessarily affect generator revenues. Seasonal wind patterns produce conflicts with the goal of managing rivers for “ecosystem services”—the maintenance or enhancement of downstream ecosystems. We illustrate our decision model using the Kerr Dam in PJM’s territory in North Carolina. We simulate the operation of Kerr Dam over a three-year period that features hydrologic variability from normal water years to extreme drought conditions. We use an optimization framework to estimate reservation prices for Kerr Dam offering wind-following services in the PJM market. Wind-following may be profitable for Kerr Dam at low capacity levels during some time periods if ecosystems services are neglected and if side payments, or reserves-type payments, are provided. Wind-following with ecosystem services yields revenue losses that typically cannot be recovered with reserves market payments. Water release patterns are inconsistent with ecosystem-services goals when Kerr Dam dedicates significant capacity to wind-following, particularly in drought years.     

Negative equity and wages

We examine the relationship between housing equity and wage earnings using nine waves of the national American Housing Survey from 1985 to 2003. Employing a rich set of time and place controls, a synthetic mortgage instrumental variable strategy, and a first difference estimator we find that people underwater on their mortgage command a significantly lower wage than other homeowners. The finding survives a number of robustness checks for reverse causality and unobserved heterogeneity. We also explore other determinants of “house lock” including loss aversion, a low existing mortgage interest rate and property tax assessment caps, but do not find these factors mitigate the effect of negative equity on wages.     

Learning from Postproject Reviews: A Cross‐Case Analysis*

Every new product development (NPD) project should not only deliver a successful new product but also should generate learning for the organization. Postproject reviews (PPRs) are recognized by both practitioners and academics as an appropriate mechanism to stimulate and capture learning in NPD teams. However, relatively few companies use PPRs, and those that do use them often fail to do so effectively. Although they are widely perceived to be a useful tool, empirical research on how PPRs are typically organized and the learning that results is limited. The present article addresses this gap in the extant knowledge and describes five in‐depth case studies, which were conducted at leading companies in Germany. A detailed investigation was made of how PPRs are conducted and of the type of learning that can result. Three main sources of data were used for each case: company documentation, in‐depth interviews with managers responsible for NPD, and observation of an actual PPR. The different data sources enabled extensive triangulation of data to be conducted and a high degree of reliability and validity to be achieved. The analysis enabled a number of key characteristics of the way PPRs are managed to be identified. Various characteristics of PPRs influence their utility, such as the time at which they take place and the way discussions are moderated. In addition, the data show that participants in the discussions at PPRs often use metaphors and stories, which indicates that PPRs have the potential to generate tacit knowledge. Interestingly, the data also show that there are various different ways in which metaphors and stories appear to stimulate discussions on NPD projects. Based on the cross‐case analysis, a wide range of implications are identified. Researchers need to investigate PPRs further to identify how they can generate tacit and explicit knowledge and support project‐to‐project learning. The generation of tacit knowledge in NPD is a topic that particularly needs further investigation. The research also led to a range of recommendations for practitioners. Companies need to strongly communicate the purpose and value of PPRs, to run them effectively to stimulate the maximum possible learning, and to disseminate the findings widely. PPRs have the potential to create and transfer knowledge amongst NPD professionals, but, as they are seldom currently used, many companies are missing an important opportunity.     

Equilibrium Underdiversification and the Preference for Skewness

We develop a one-period model of investor asset holdings whereinvestors have heterogeneous preference for skewness. Introducingheterogeneous preference for skewness allows the model's investors,in equilibrium, to underdiversify. We find support for our model'sthree key implications using a dataset of 60,000 individualinvestor accounts. First, we document that the portfolio returnsof underdiversified investors are substantially more positivelyskewed than those of diversified investors. Second, we showthat the apparent mean-variance inefficiency of underdiversifiedinvestors can be largely explained by the fact that investorssacrifice mean-variance efficiency for higher skewness exposure.Furthermore, we show that idiosyncratic skewness, and not justcoskewness, can impact equilibrium prices. Third, the underdiversificationof investors does not appear to be coincidentally related toskewness. Stocks most often selected by underdiversified investorshave substantially higher average skewness—especiallyidiosyncratic skewness—than stocks most often selectedby diversified investors.
