Budget-constrained Pareto-efficient allocations

This paper is concerned with a study of budget-constrained Pareto-efficient (BCPE) allocations, i.e., allocations which given a price system satisfy a given income distribution. We prove existence, show structural stability, and establish a sufficient condition for uniqueness of BCPE allocations. These properties of the BCPE allocations are deduced from similar properties of Walrasian equilibria by a duality theory which is of independent interest.     

SOCIAL NETWORKS AND CRIME DECISIONS: THE ROLE OF SOCIAL STRUCTURE IN FACILITATING DELINQUENT BEHAVIOR*

Delinquents compete with each other in criminal activities but benefit from being friends with other criminals by learning and acquiring proper know‐how on the crime business. We study the subgame‐perfect Nash equilibrium of this game in which individuals decide first to work or to become a criminal and then the crime effort provided if criminals. We show that multiple equilibria with different numbers of active criminals and levels of involvement in crime activities may coexist and are only driven by the geometry of the pattern of links connecting criminals.     

The evolution of cooperation in strategic alliances: Initial conditions or learning processes?

We examine how the learning, along several dimensions (environment, task, process, skills, goals), that takes place in strategic alliances between firms mediates between the initial conditions and the outcomes of these alliances. Through a longitudinal case study of two projects in one alliance, replicated and extended in another four projects in two alliances, a framework was developed to analyze the evolution of cooperation in strategic alliances. Successful alliance projects were highly evolutionary and went through a sequence of interactive cycles of learning, reevaluation and readjustment. Failing projects, conversely, were highly inertial, with little learning, or divergent learning between cognitive understanding and behavioral adjustment, or frustrated expectations. Although strategic alliances may be a special case of organizational learning, we believe analyzing the evolution of strategic alliances helps transcend too simple depictions of inertia and adaptation, in particular by suggesting that initial conditions may lead to a stable ‘imprinting’ of fixed processes that make alliances highly inertial or to generative and evolutionary processes that make them highly adaptive, depending on how they are set.     

Out-of-equilibrium price dynamics

A trading-post organization of exchange is shown to determine an out-of-equilibrium price dynamics. The unique equilibrium of quasi-linear economies (defined by log-linear utility functions) is stable for the discrete time version of the dynamics. Equilibria that are stable for the continuous time version include those that satisfy the gross-substitutability property, the no-trade equilibria and, more generally, those for which trade intensity is relatively small. In addition, the set of stable equilibria is path-connected when endowments are allowed to vary without sign restrictions.      

Core rationalizability in two-agent exchange economies

Summary. We provide a characterization of selection correspondences in two-person exchange economies that can be core rationalized in the sense that there exists a preference profile with some standard properties that generates the observed choices as the set of core elements of the economy for any given endowment vector. The approach followed in this paper deviates from the standard rational choice model in that a rationalization in terms of a profile of individual orderings rather than in terms of a single individual or social preference relation is analyzed.

Are shirking and leisure substitutable? An empirical test of efficiency wages based on urban economic theory

Recent theoretical work has examined the spatial distribution of unemployment using the efficiency wage model as the mechanism by which unemployment arises in the urban economy. This paper extends the standard efficiency wage model in order to allow for behavioral substitution between leisure time at home and effort at work. In equilibrium, residing at a location with a long commute affects the time available for leisure at home and therefore affects the trade off between effort at work and risk of unemployment. This model implies an empirical relationship between expected commutes and labor market outcomes, which is tested using the Public Use Microdata sample of the 2000 U.S. Decennial Census. The empirical results suggest that efficiency wages operate primarily for blue collar workers, i.e. workers who tend to be in occupations that face higher levels of supervision. For this subset of workers, longer commutes imply higher levels of unemployment and higher wages, which are both consistent with shirking and leisure being substitutable.     

Large Shareholder Entrenchment and Performance: Empirical Evidence from Canada

Abstract:  Recent empirical evidence indicates that the largest publicly traded companies throughout the world have concentrated ownership. This is the case in Canada where voting rights are often concentrated in the hands of large shareholders, mostly wealthy families. Such concentrated ownership structures can generate specific agency problems, such as large shareholders expropriating wealth from minority shareholders. These costs are aggravated when large shareholders don't bear the full costs of their decisions because of the presence of mechanisms (dual class voting shares, pyramids) which lead to voting rights being greater than the cash flow rights (separation). We assess the impact of separation on various performance metrics while controlling for situations when the large shareholder has (1) the opportunity to expropriate (high free cash flows in the firm) and (2) the incentive to expropriate (low cash flow rights). We also control for when the large shareholder has the power to expropriate (high voting rights, outright control and insider management) and for the presence of family ownership. The results support our hypotheses and indicate that firm performance is lower when large shareholders have both the incentives and the opportunity to expropriate minority shareholders.     

Imperfections and Shortcomings of the Stakeholder Model’s Graphical Representation

The success of the stakeholder theory in management literature as well as in current business practices is largely due to the inherent simplicity of the stakeholder model––and to the clarity of Freeman’s powerful synthesised visual conceptualisation. However, over the years, critics have attacked the vagueness and ambiguity of stakeholder theory. In this article, rather than building on the discussion from a theoretical point of view, a radically different and innovative approach is chosen: the graphical framework is used as the central perspective. The major shortcomings of the popular stakeholder framework are systematically confronted with the graphical scheme to illustrate their visual impact. The graphical illustrations of the imperfections help explain the sometimes-oversimplified generalisation inherent to every graphical model. They also make some interrelationships easier to understand. The analysis demonstrates that, with the tacit but implicit acceptance of simplification of the discussed explanatory elements, Freeman’s framework remains a rather good approximation of reality. Only a few minor changes to the stakeholder model are consequently proposed.     

Professional–Organisational Commitment: A Study of Canadian Professional Accountants

This paper extends the literature on professional and organisational commitment through an online survey of professional accountants that examines the influence of several contextual features; namely, workplace diversification, occupational stress, professional involvement and culture. The survey was carried out around the end of 2002 with Canadian chartered accountants (CAs) from four Canadian provincial institutes. Three of these provincial institutes are located in English-speaking provinces (Alberta, British Columbia and Nova Scotia), while the fourth CA association is in Quebec, a predominantly French-speaking province. In contrast to prior research carried out more than two decades ago, our results indicate that respondents in public practice do not differ from respondents in non-public accounting settings in their level of professional commitment and in their level of organisational commitment. Our results also suggest that occupational stress and professional involvement are both significantly related to professional commitment. Finally, our survey data indicate that accountants working in Quebec had a lower professional commitment than their peers working in English-speaking provinces, thereby suggesting that culture exerts significant influence on professional commitment.
