The paper extends a result in Dutta and Ray's (1989) theory of constrained egalitarianism initiated by relying on the concept of proportionate rather than absolute equality. We apply this framework to redistributive systems in which what the individuals get depends on what they receive or pay qua members of generally overlapping groups. We solve the constrained equalization problem for this class of models. The paper ends up comparing our solution with the alternative solution based on the Shapley value, which has been recommended in some distributive applications

Consumer Attitude Toward Brand Extensions: An Integrative Model and Research Propositions


International Journal of Research in Marketing

2003, vol. 20, n°1, pp.97-115

Départements : Marketing

Mots clés : Brand extensions, Consumer attitudes, Brand associations, Brand affect, Cognitive psychology

The paper proposes an integrative model of the antecedents and consequences of brand extension attitude based on the dominant cognitive paradigm. The four key processes of the model are (1) the perception of fit, (2) the formation of primary attitudes toward the extension, (3) the link between extension attitude and marketplace behaviour and (4) the reciprocal effect of brand extension attitude on parent brand/extension category attitude. Moderator and control variables of these processes are identified and classified into three groups: (1) consumer characteristics, (2) marketer-controlled factors and (3) external factors. This integrative model leads to the identification of missing links and variables in past research, resulting in a propositional inventory for future studies. The paper ends with a reflection on the long-term perspectives of scientific inquiry on brand extensions

Corporate Walkout Decisions and the Value of Default

We present a continuous-time asset pricing model of the levered firm where shareholders select not only the timing but also the form of abandonment. Shareholders can walk out of the firm either by (i) defaulting on their debt obligations or (ii) selling their shares to alternative operators of the technologies, as in a corporation sale. The structural model relates shareholders' ex-post choice to both technological and financial factors. Considering that operators' technological supremacy is not universal, we obtain that whereas default necessarily involves an inefficient timing of ownership transfer, corporation sales do not. Then, the likelihood of default being chosen instead of a corporation sale increases with (i) the degree of leverage displayed by the firm and (ii) its technological supremacy. By ignoring corporation sales, existing defaultable bond pricing models have thus a tendency to exaggerate risk premia and underestimate the borrowing ability (debt capacity) of firms

Cultural Impact on European Staffing Policies in Sales Management

Mots clés : Sales force management, Staffing decisions, International human resource management, Cultural values, Managerial values

This paper tests propositions derived from the sales and human resource management literature about the adoption of sales personnel recruitment and promotion policies in an international context through a comparative study of managers in six European countries. The results indicate that the regional culture of decision-makers has a strong effect on their choice of recruitment and promotion candidates. This study attempts to identify key sales personnel characteristics for international staffing policies.

Deterministic Multi-Player Dynkin Games

A multi-player Dynkin game is a sequential game in which at every stage one of the players is chosen, and that player can decide whether to continue the game or to stop it, in which case all players receive some terminal payoff.We study a variant of this model, where the order by which players are chosen is deterministic, and the probability that the game terminates once the chosen player decides to stop may be strictly less than 1.We prove that a subgame-perfect <F>?</F>-equilibrium in Markovian strategies exists. If the game is not degenerate this <F>?</F>-equilibrium is actually in pure strategies.
