ECONOMIC ACTIVITY IN THE SHADOW OF CONFLICT

Appropriation possibilities significantly alter economic fundamentals in a production and exchange economy. This is the primary lesson of our model, which combines Ricardian trade and the potential for predator/prey behavior. The model shows how conflict can be subdued by mutual gains from trade, but at a resource cost that modifies the exchange itself. On the other hand, it identifies conditions wherein appropriation incentives are so strong that specialized production and trade are precluded altogether. The model also reveals a new way to think about and measure the gains from trade. ( JEL C72, D51, D74, F10)     

UNIFORM TWO-PART TARIFFS AND BELOW MARGINAL COST PRICES: DISNEYLAND REVISITED

This paper completely characterizes the demand and cost parameters which induce a constant cost monopolist charging a uniform two-part tariff to choose a marginal price less than marginal cost when selling to two types of consumers with different linear demands. It also provides a quantitative assessment of the potential significance of such pricing. Pricing below marginal cost maximizes profits in large regions of the model parameter space, contrary to widely held beliefs. If fixed costs are zero, pricing below marginal cost can increase profits by a factor of √2, although for most parameters the profit increase is much smaller. ( JEL D42, L11)     

Competence and Competitive Advantage: Towards a Dynamic Model

Over the last ten years the concept of ‘competence’ has emerged as a central concept for competitive strategy. Several rich theoretical streams have contributed an extensive array of frameworks, definitions and papers using the concept. There is now a need to integrate these many contributions. Indeed, some of the frustration expressed recently by academics may be due to the large volume of conversation and the low level of integration. A concept that is considered so useful that many writers have incorporated it in their work will be of little value if it takes on different meanings for every use. If competence is to be used to explain relationships among variables and to build richer understandings of the roots of competitive advantage, then the field needs to engage in a serious conversation that attempts to focus this concept. Competence needs to be understood in a way that is faithful to its theoretical roots, allows the multiple dimensions that underpin competitive advantage to be meaningfully integrated and is specific enough that meaningful differences can emerge when used as a variable in empirical research. This paper seeks to begin a conversation toward that end by presenting a conceptualization that meets all of these requirements. The paper builds its conceptualization around satisfying the elements of a dynamic model of the relationship between competence and competitive advantage.     

Linear Aggregation of SSB Utility Functionals

A necessary and sufficient condition for linear aggregation of SSB utility functionals is presented. Harsanyi's social aggregation theorem for von Neumann–Morgenstern utility functions is shown to be a corollary to this result. Two generalizations of Fishburn and Gehrlein's conditional linear aggregation theorem for SSB utility functionals are also established.     

Postmodernism, philosophy and management: concepts and controversies

The paper offers a (partial) review of the philosophy of postmodernism as it applies to social science in general and management and organization theory in particular. Initially, some of the main analytical perspectives of postmodernism and post-structuralism are explored, notably those relating to epistemology and ethno-industrial change. Subsequently, we review concepts which lie at the heart of the 'postmodern mood' in social philosophy and sociology; for example, representation, reflexivity, deconstruction and decentring. In so doing, we take reference to the works of Jean Baudrillard, Jacques Derrida and Jean-François Lyotard amongst others Finally, this philosophical assessment review forms the basis for an analysis of postmodernism as an emerging paradigm of management and organization theory. The works of key postmodernist writers in management and organization studies are reviewed and case examples of postmodern research presented.     

THE BOYS IN BLUE AND THE BAD BLUE BOYS: A CASE STUDY OF INTERACTIVE RELATIONS BETWEEN THE POLICE AND ETHNIC YOUTH IN WESTERN SYDNEY

The paper draws on ethnographic fieldwork undertaken with a group of young men known collectively as the Bad Blue Boys (BBB)¹. These young men use the supporting of a soccer team (Sydney United in the national league) as a means of parading nationalistic allegiance to their parent's homeland, Croatia. Given the history of crowd conflict at Australian soccer matches and the current trends within soccer officialdom to move the sport away from its traditional affiliation with ethnic communities, it is inevitable that the BBB have come into confrontation with agents of social authority, such as the police, during an afternoon at the football. The participant observation aspect of the research is used to discuss the interaction between the police and the BBB at soccer matches, while interviews with members of the BBB are recounted to reveal group attitudes held about the police. The paper is written to articulate with other academic contributions which have investigated the relationship between youth from non-English speaking backgrounds (NESB) and the police in contemporary Australian urban contexts. A leading contributor to such studies, Janet Chan, has commented, ‘Australian research specifically on police-ethnic youth relations [paints] a negative portrait’ (Chan 1994, p. 176). The portrait painted by the present study is intended for comparison with such research. At the outset it must be stressed that the findings are peculiar to the study and that no great claim is made for extrapolation. However, this is not to say that the study does not reflect trends in relations between NESB youth and police in Australian cities. On the contrary, a conclusion will be drawn which argues that ethnographic studies of particular ethnic youth groupings and subcultures facilitate a social mapping of police youth relations.     

Are Groups More (or Less) Consistent Than Individuals?

There is now overwhelming experimental evidence that individuals systematically violate the axioms of Expected Utility theory. In reality, however, many economic decisions are taken by, or on behalf of, groups whose members have a joint stake in those decisions. This paper reports on an experiment in which pairs of individuals are tested for Common-Ratio inconsistencies. We find that the agreed choices of subject-pairs follow a pattern of inconsistency very close to that of individuals' choices. We also look for evidence that group participation increases the consistency of the individuals themselves. With one solitary exception, we find none.     

Social europe,social citizenship,and social services

The article begins by considering moves to establish Social Europe, alongside the European Unions single market, and the emphasis within the formulation of Social Europe on an employment-based model of social citizenship. This employment-based model is considered to be too limited for application to the social services. Accordingly, two other models are placed within the context of continuing European debate. These models are termed state clienthood and state-sponsored consumerism. The social democratic model of state cli-enthood is considered to be flawed by its neglect of the power exercised by the state over users of social services and by its lack of concern with individual needs. The potential of state-sponsored consumerism to open up questions concerning the rights of users of social services and responsiveness to their individual needs is explored and the conclusion is reached that, despite its inauspicious beginnings as part of the New Rights reform programme, this model has possibilities for enhancing social citizenship. Procedural rights offered by state-sponsored consumerism not only can extend social citizenship within existing social services provision but also can serve as a precursor to the wider participation of citizens in the social services, as the site of a continuing struggle around their rights.
