Bivariate income distributions with lognormal conditionals

In this paper, the most general bivariate distribution with lognormal conditionals is fully characterized, using the methodology proposed by [3]. The properties of the new family are studied in detail, including marginal and conditional distributions, regression functions, dependence measures, moments and inequality measures. The new distribution is very broad, and contains as a particular case the classical bivariate lognormal distribution. Several subfamilies are studied and a generalization of the basic model is discussed. Finally, we present an empirical application. We estimate and compare the basic model proposed in the paper with a classical model, using data from the European Community Household Panel in different periods of time.     

Nonmanipulable decision mechanisms for economic environments

In the social choice literature studying the problem of designing institutions for collective decision making, it is customary to (implicitly) assume that each dimension of the social outcome is of public interest (i.e., that each individual's welfare depends on every dimension of the outcome). Thus, the scope of the conclusions obtained is very limited. Here social decision problems with and without that public character are considered and it is shown that the same negative results arise in most cases; namely, that only dictatorial mechanisms are immune to the participants' manipulations. These results are obtained without requiring that the mechanisms produce Pareto optimal outcomes (they must simply be minimally responsive to the participants' preferences), which deepens their pessimistic character.I am deeply grateful to my advisor, Mark Walker, for his continuous guidance and encouragement. I wish also to thank Salvador Barberà, John Weymark, and two anonymous referees for helpful comments.

L’adaptation des modèles de production dans les pays émergents L’exemple de l’industrie automobile en Argentine

How to test for the existence of a new model of production based on the firm lending an ear to customer demands and valuing the individual and collective intelligence of its work force? The facts for putting this model to the test of reality come from an analysis of two Argentinean automobile-makers, subsidiaries of Toyota and Volkswagen. Various aspects of their organization policy provide evidence of their capacity for making adaptations by “hybridizing” the parent firm’s model with the rationales inherent in the network of local actors (suppliers and labor unions, in particular). These firms are open systems with a narrow margin of maneuver. — Special issue: Latin America.     

Transitional socioeconomic and political environments of public relations in Mexico

This qualitative research on the socioeconomic and political environments of public relations in Mexico documents how national context influences the practice of the profession. The evolution of public relations in Mexico has accelerated since the establishment of the North America Free Trade Agreement with the United States and Canada. This advancement is attributed to the practices of transnational corporations and the democratization process that motivates openness, greater professionalism and the expansion of public relations across diverse organizations.     

The effects of breastfeeding and pace of childbearing on mortality at early ages

The effects of the pace of childbearing and breastfeeding practices on infant mortality have rarely been considered together. In this paper, we design and use a set of methodological tools to test a variety of hypotheses postulating the effects of breastfeeding and pace of childbearing on mortality in infancy and early childhood, the mechanisms through which those effects operate, and the contingencies that strengthen or weaken them. The strong effects of both length of breastfeeding and the pace of childbearing on the risks of child death suggest that neither of them exerts an impact on mortality totally mediated by the other. Social and demographic factors (such as age of child, education of mother, and region of residence) also condition the impact of breastfeeding and pace of childbearing on mortality.
