Implementation of allocation rules under perfect information

We study subgame perfect implementation through perfect information mechanisms in economic environments. We assume that worst bundles exist for each agent and can be assigned to them independently of the bundle assigned to at least one other agent. We restrict our attention to allocation rules that are anonymous, efficient on their own range, single-valued in welfare, and that induce agents' participation. We define a class of mechanisms, which satisfy properties of minimal path length and finiteness of message dimensions. We characterize the class of allocation rules which can be implemented through those mechanisms.I would like to thank Bhaskar Dutta, Louis Gevers, Matthew Jackson, Ozgur Kibris, Hervé Moulin and Arunava Sen for stimulating discussions, seminar participants at Université de Montréal (the Axiomatic Theory of Resource Allocation meeting, May 1996), Universitat Autonoma de Barcelona, Universitad Carlos III de Madrid and Université de Paris Dauphine for their comments, and Frédéric Gaspart, Tarik Kara, James Schummer, William Thomson and an anonymous referee for extremely useful comments and suggestions on earlier versions.

Fair Production and Allocation of an Excludable Nonrival Good

We study fairness in economies with one private good and one partially excludable nonrival good. A social ordering function determines for each profile of preferences an ordering of all conceivable allocations. We propose the following Free Lunch Aversion condition: if the private good contributions of two agents consuming the same quantity of the nonrival good have opposite signs, reducing that gap improves social welfare. This condition, combined with the more standard requirements of Unanimous Indifference and Responsiveness, delivers a form of welfare egalitarianism in which an agent's welfare is measured by the quantity of the nonrival good that, consumed at no cost, would leave her indifferent to the bundle she is assigned.     

Increasing women's contribution on board decision making: The importance of chairperson leadership efficacy and board openness

In the last decade, the number of women on corporate boards has increased slightly, but the prevailing minority status of women directors implies that they will continue to face social barriers. While prior research has largely focused on explaining social barriers (e.g., being categorized as an out-group member) to increase diversity and its negative consequences, how boards can avoid these obstacles remains unclear. Stemming from recategorization theory, we examine whether and to what extent board chairperson leadership efficacy and board openness (as mechanisms to avoid out-group bias) enhance the influence of women when they are in the minority in board decision-making. In a sample of 146 Norwegian firms, we found a positive relationship between women minorities and women directors’ contribution to board decision-making. Moreover, we found that this positive impact increases when the board chairperson exercises leadership and the board operates in an atmosphere of openness.

The Touchard distribution

We present a novel model, which is a two-parameter extension of the Poisson distribution. Its normalizing constant is related to the Touchard polynomials, hence the name of this model. It is a flexible distribution that can account for both under- or overdispersion and concentration of zeros that are frequently found in non-Poisson count data. In contrast to some other generalizations, the Hessian matrix for maximum likelihood estimation of the Touchard parameters has a simple form. We exemplify with three data sets, showing that our suggested model is a competitive candidate for fitting non-Poisson counts.     

The International Migration System Between Turkey and Russia: Project‐Tied Migrant Workers in Moscow

The last 50 years of emigration history in Turkey indicate that the migratory flows of Turkish citizens have consecutively become a part of various migratory systems. In this essay, our main aims are twofold. First, we attempt to document the dynamics and mechanism of project‐tied migration from Turkey to the Russian Federation, focusing in particular on the case of project‐tied workers migrating from Turkey to Moscow. Second, this effort intends to elaborate on the research on migratory systems between Turkey and the former communist countries of Eastern Europe and Central and Northern Asian countries, mainly referring to macro‐, micro‐ and meso‐level factors affecting the relevant migration systems. In this paper, in which we tackle the various migration systems with which Turkey is involved, we conclude by arguing that parallel to the new migration patterns that have been experienced throughout the post‐Soviet geographies, the internalization process of Turkish constructors within the changing dynamics of Turkish foreign policy has widened the direction of the migration flows from Turkey by introducing new migrant worker profiles to different regions. In this sense, short‐term labour migrants, shuttle traders and in particular project‐tied migrant workers show not only the important role that migrants may play in the shift towards a market‐based economy in the Russian Federation, but also how they have become crucial actors of the migration system between Turkey and Russia.
