Choice Certainty and Consistency in Repeated Choice Experiments

The main objective of this study is to examine how repeated choice affects preference learning in stated preference experiments. We test different hypotheses related to preference learning by analyzing response patterns and asking respondents in a choice experiment to report their experienced certainty when going through the choice tasks. In a split-sample test, we show that follow-up choice certainty questions are procedural invariant. The self-reported certainty results indicate that learning occurs, but econometric testing procedures do not identify any significant impact of learning effects on parameter estimates or variance across choice tasks. Additional tests of choice consistency suggest that preferences in the choice experiment are stable and coherent.     

Variety,Globalization, and Social Efficiency

The standard formal presentation of the Dixit‐Stiglitz‐Krugman (DSK) model of monopolistic competition with a constant‐elasticity‐of‐substitution (CES) utility function supposes a sufficient number of firms so that the elasticity of demand facing each variety is approximated by a constant elasticity of substitution. Such a formulation forces economies of scale to be frozen so that firm size never changes. We use a Bertrand‐Nash interpretation of the equilibrium that allows the elasticity of demand facing each variety to depend on the number of varieties, thus allowing the gains from globalization to reflect both the increase in variety and the exploitation of economies of scale. We also develop a precise expression for per capita real income with any number of sectors and examine the age‐old question of the socially optimal number of varieties.     

The strategic management of re-innovation

Abstract
Most studies of the management of the technological innovation process cover the range of activities that culminate in the commercial introduction of a new product. In certain sectors of industry, however, especially those characterised by extended product lifecycles, continued competitiveness depends on vigorous and continuous product improvement, i.e. on the process of 're-innovation' to satisfy evolving user requirements. Ongoing research at SPRU has investigated the process of re-innovation in a number of industry sectors, and the paper presents material relating to two of the characteristic patterns of re-innovation identified in this research.
The first characteristic pattern is re-innovation combining the existing with the new. Two brief case studies are presented. In both cases, the manufacturer and customer gained significant benefits from this re-innovation strategy. For the manufacturer there were reduced development and testing costs, scale and learning curve benefits, distributed inventories of spares and servicing experience. For the customer there were familiarity benefits and reduced entry risks associated with proven reliability of parts and sub-systems.
The second, and more general pattern of re-innovation is based on the concept of the 'robust design'. This is a basic design which has sufficient inherent technological slack or flexibility to enable it to evolve into a significant design family of variants. Product design families offer the producer economies of scale in R&D, manufacturing, marketing and sales and servicing. They offer the user learning from experience, the enhanced possibility of user-inspired modifications, a wider range of price/ performance packages and rapid adaptations to changing environments. Robust designs can effectively combine economies of scale with economies of scope; they are strategically more flexible than leanly configured designs which satisfy only transient user requirements.     

Personal value systems of Japanese trainees and managers in a changing competitive system

A study of personal values held by Japanese and foreign students, trainees and managers showed recent Japanese trainees slightly more conservative than their 1979 cohorts. Foreign students and foreign managers held more pro-American work values than either Japanese managers or trainees. Finally, for the Japanese respondents, there was some evidence of specific shifts away from the Japanese employment system in the areas of thenenko compensation and promotion systems in their organisations.Roy J.

A note on cross-impact analysis: a calculus for sequence-dependent events

As the example presented demonatrate, the analysis of cross-impactss amount a group of related events is somewhat more complex than perhaps heretofore imagined. Impacts of effects between such events very often carely depend on their temporal sequence. The event outcome space is accordingly multiplied considerably over the case where such dependency is ignored. The result is that high premium is placed on methods that seek to reduce analytical complexity without distorting essential event intrications.     

Ethical and Unethical Bargaining Tactics: An Empirical Study

Competitive negotiators frequently use tactics which others view as "unethical", in that these tactics either violate standards of truth telling or violate the perceived rules of negotiation. This paper sought to determine how business students viewed a number of marginally ethical negotiating tactics, and to determine the underlying factor structure of these tactics. The factor analysis of these tactics revealed five clear factors which were highly similar across the two samples, and which parallel (to a moderate degree) categories of tactics proposed by earlier theory. Data from one sample also permitted comparisons of the appropriateness of certain tactics across gender, nationality, ethnic origin and perception of one's negotiating style.     

The ubiquitous tourist brochure explorations in its intended and unintended use

The format and content of tourist attraction brochures are examined. Emphasis is on their function in encouraging tourists to establish authentic “traveler-like” personal contact with the local people and area. The Old Order Amish community in Lancaster County, Pennsylvania, is the setting studied. Findings indicate that brochures advertising staged tourist attractions implicity encourage tourists to move away from contact with the indigenous population and culture. Attractions are presented as convenient, efficient, and authentic means of “sampling” the region. Questions are raised about the probable consequences for a local area and its people, should large numbers of tourists choose to seek our direct and “authentic” contact with the indigenous community. It may be the staged attractions, while often the object of intellectual critique, protect the community from the pressures of mass tourism.     

Why statutory union recognition is bad labour policy:the North American experience

The proposed British legislation is modelled on that of the United States which has been a clear failure in its stated goal of encouraging the practice and procedure of collective bargaining (Adams, 1993). It has instead perpetuated a culture of labour-management animosity that many other nations have 113been able, to their benefit, to overcome (Adams, 1995c).
