Multidimensional Screening in Insurance Markets with Adverse Selection

Bundled coverage of different losses and distinct perils, along with differential deductibles and policy limits, are common features of insurance contracts. We show that, through these practices, insurers can implement multidimensional screening of insurance applicants who possess hidden knowledge of their risks, and thereby reduce the externality cost of adverse selection. Competitive forces drive insurers to exploit multidimensional screening, enhancing the efficiency of insurance contracting. Moreover, multidimensional screening allows competitive insurance markets to attain pure strategy Nash equilibria over a wider range of applicant pools, resolving completely the Rothschild–Stiglitz nonexistence puzzle in markets where the perils space is sufficiently divisible.     

Comparative research in industrial relations: helping the survey cross frontiers

There has been a relative dearth of comparative, cross-national research which has followed a survey-based approach. This partly reflects the difficulty that researchers encounter in collecting such information, either via primary collection or the secondary matching of existing survey material. This paper addresses these difficulties and suggests ways in which their impact can be minimized. It notes that such difficulties are much more severe in the case of secondary matching and are thereby likely to constrain the scope of this approach. They are not totally absent in primary collection and it is suggested that there are limits to what can be achieved during data collection to promote the development of like data-sets across countries. This indicates that great care must be taken in interpreting data so obtained. Despite such limits and cautions, it is nevertheless concluded that the survey approach can be an important adjunct to the process of understanding why the world of work varies across frontiers.     

The Innovative Performance Of The World'S Largest Firms: Some New Evidence ‡

Data on R & D expenditures and US patenting in the world's 660 largest, technologically active firms both show a linear relation between firm size and the volume of innovative activities, despite some inconsistencies between the two measures. Technological diversity increases with firm size, but relatively weakly, especially in R & D-intensive sectors. Sectoral variations in the comparative technological advantage of large firms based in Japan, the USA and W. Europe are better explained by variations in rivalry in their home market than by variations in their size.     

Land Tenure and the Adoption of Conservation Practices

We use a logit adoption model with data on 941 U.S. corn producers from the 1996 Agricultural Resource Management Study to analyze the influence of land tenure on the adoption of conservation practices. We extend previous analyses by distinguishing renters according to lease type and by distinguishing practices according to the timing of costs and returns. We find that cash-renters are less likely than owner-operators to use conservation tillage, but share-renters are not. Both cash-renters and share-renters are less likely than owner-operators to adopt practices that provide benefits only over the longer term (grassed waterways, stripcropping, and contour farming).     

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.     

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.
