Condorcet cycles in bipartite populations

Summary. Simple majority voting between pairs of alternatives is used to aggregate individual preferences. The occurence of Condorcet cycles is limited thanks to a principle of homogeneity on individual preferences. The restrictions induced on the domain of the latters are weak: among the n! possible orderings of n alternatives, more than one half are admissible within a domain. The resulting aggregated preference has then a neglectable probability of showing up cycles. We show moreover that the set of individual preferences can be `naturally' partitioned into two such domains. Received: June 17, 1996; revised version: April 15, 1997     

Mythical representations of trust in auditors and the preservation of social order in the financial community

The present paper investigates financial practitioners’ use and perception of audited financial statements. In-depth interviews, which we conducted with Canadian institutional investors, financial analysts and bankers, indicate: (1) a firm tendency to favour the quality of management over the content of financial statements in investment decisions and recommendation processes; and (2) a fundamental scepticism regarding the work of auditors. However, representations of auditor trustworthiness abound in formal texts surrounding the financial analysis domain—as if audited financial statements and the trust they convey towards numbers are indispensable to the work of financial analysts. Based on the work of Roland Barthes, we argue that financial practitioners’ trust in auditors constitutes a mythical representation whose main function is to maintain order and reproduce status quo within the financial system.     

On the satisfaction of peak demand in the certainty case

The concept of full-capacity flat-rate equilibrium is explored for a version of the Arrow-Debreu model with time-differentiated goods and production subject to a capacity constraint. The corresponding equilibrium allocations are shown to be inefficient in general. It is also shown that rationing peak demand is Pareto superior to non-rationing.     

Job matching, social network and word-of-mouth communication

Workers can find a job either directly or through personal contacts. From this micro scenario, we derive an aggregate matching function that has the standard properties but fails to be homogeneous of degree one. We show that, when the network size increases, on average, the unemployed workers hear about more vacancies through their social network. However, above a certain critical value, job matches decrease with network size. We then establish existence and uniqueness of the labor market equilibrium and study its properties. Finally, we demonstrate that the decentralized market equilibrium is not efficient because of both search and network externalities.     

Does City Structure Affect Job Search and Welfare?

We develop a model in which workers' search efficiency is negatively affected by access to jobs. Workers' location in a city is endogenous and reflects a trade-off between commuting costs and the surplus associated with search. Different configurations emerge in equilibrium; notably, the unemployed workers may reside far away (segregated city) or close to jobs (integrated city). We prove that there exists a unique and stable market equilibrium in which both land and labor markets are solved for simultaneously. We find that, despite inefficient search in the segregated city equilibrium, the welfare difference between the two equilibria is not so large due to differences in commuting costs. We also show how a social planner can manipulate wages by subsidizing/taxing the transport costs and can accordingly restore the efficiency.     

Global models applied to agricultural and trade policies: a review and assessment

The continuing process of global integration bears implications for farmers and related supplying and processing industries in all parts of the world, but also for the rest of the world economy. An assessment of agricultural and trade policy impacts is bound to be complex and is often supported by quantitative modeling analysis. This article provides an assessment of the present state of applied modelling in the area of trade and agricultural policies. We provide in this paper a comparative assessment of alternative modelling approaches, considering a total of 16 partial equilibrium and general equilibrium models. The assessment includes theoretical modelling foundations, datasets employed and institutional aspects, such as model maintenance and dissemination of results. A typology of models is provided by structuring the assessment along a clear set of evaluation criteria.

The Impact of Internal Corporate Social Responsibility on Organizational Commitment: Evidence from Vietnamese Service Firms

This study examines the relationship between internal corporate social responsibility (CSR) and organizational commitment in the service sector in Vietnam. Results from a survey of 256 employees indicate that internal CSR has a positive and significant correlation with organizational commitment. More specifically, labor relations, health and safety, and training and education had a significant effect on organizational commitment whereas work–life balance and social dialogue have no significant association with organizational commitment. The authors also provide implications, limitations, and recommendations for future research.     

Business ethics research at the world's leading universities and business schools

This paper explores the role of the leading universities and best-ranked business schools in the evolution of the academic field of business ethics. An advanced bibliometric methodology is applied to publications in business ethics from the major universities of the Shanghai ARWU ranking and from the FT-ranked business schools. The comprehensive bibliometric study encompasses multiple indicators and examines the evolution of business ethics publications over time. Business ethics research is built on two complementary interdisciplinary streams of research, philosophy, and management. The study indicates that it were not the top universities that contributed most to research advancements in the field of business ethics but second and third tier universities. This finding suggests that academic research in new subfields constitutes a niche strategy for universities and business schools to differentiate themselves. The study furthermore highlights the prominent role of the product champion or ‘idea champion’ in management research at universities. The diffusion of business ethics research illustrates the possibilities for lower ranked business schools with lower budget to excel in specialised subfields and interdisciplinary subthemes.     

Determinants of demand for green products: An application to eco-label demand for fish in Europe

In this paper, we confront the theoretical motivations of the consumption of eco-friendly products and the factors influencing the European perceptions regarding the fact that “fish caught using an environmentally friendly technique may carry a special label”. We take advantage of the recent integration of non-economic elements in the microeconomic analysis of consumers' behavior in order to highlight the factors leading to their demand for green products. Thanks to an original European survey on seafood product carried out on more than 5000 consumers, we test the influence of intrinsic motivation, information, localization and socio-economic factors on the demand for an eco-label for fish.Our results show a significant connection between the desire for eco-labeling and seafood features, especially the freshness of the fish, the geographical origin of the fish and the wild vs farmed origin of the fish. Moreover, we prove the major role played by the fish price. We also demonstrate that the ecological issue regarding fisheries is highly connected to consumer information, intrinsic motivation and socio-economic status: the typical “green fish consumer” is a young woman, well educated, well informed on the state of marine resources and not very trusting of the regulation of the fisheries. Consumers who are aware of the importance of marine resource preservation have the same profile.
