Arrovian theorems for economic domains: Assignments,matchings and pairings

In this paper, we show that Arrow's and Wilson's theorems hold for permutation, symmetric permutation and symmetric domains. Permutation domains concern assignments: n indivisible private goods are distributed betweenn selfish individuals. Symmetric permutation domains concern matchings: two sets ofn selfish individuals being given, pairs with an individual from each set are to be made. Symmetric domains concern pairings: a set of 2n selfish individuals being given,n pairs of individuals are to be made.We thank two anonymous referees for helpful suggestions.     

The minimal overlap rule revisited

This paper provides an analysis of the Minimal Overlap Rule, a solution for bankruptcy problems introduced by O’Neill (1982). We point out that this rule can be understood as a composition of Ibn Ezra’s proposal and the recommendation given by the Constrained Equal Loss Rule. Following an interpretation of bankruptcy problems in terms of TU games, we show that the Minimal Overlap Value is the unique solution for bankruptcy games which satisfies Anonymity and Core Transition Responsiveness.     

Ethnic Transformation in Rural California: Looking Beyond the Immigrant Farmworker

Abstract Communities in rural California are becoming increasingly Latino. Using a quantitative database of 288 rural communities, together with qualitative data collected in the San Joaquin Valley, we examine the processes through which this ethnic transformation is occurring. Most studies have focused on Latino immigration as the cause of changing ethnic composition. We find that non-Latino population growth, as well as Latino population growth, accounts for the relative differences in changing community ethnicity. Most important for explaining migration among Latinos are housing costs and year-round job availability. Among white non-Latinos, ethnic conflict and perceptions of community deterioration better explain migration decisions. As a result of these changes, places in rural California are becoming increasingly economically and ethnically differentiated.     

Gamson’s law and hedonic games

This note adds one celebrated coalition formation game due to Gamson (Am Soc Rev 26:373–382 1961a, Am Soc Rev 26:565–573, 1961b) in the list of applications of the theory of hedonic games explored by Banerjee et al. (Soc Choice Welf 18:135–153, 2001) and Bogomolnaia and Jackson (Games Econ Behav 38: 204–230, 2002). We apply their results to study the original Gamson game and offer extensions both to a multi-dimensional characteristics space and to an infinite number of players.

Influence diagnostics in the capital asset pricing model under elliptical distributions

In this paper we consider the Capital Asset Pricing Model under Elliptical (symmetric) Distributions. This class of distributions, which contains the normal distribution, t, contaminated normal and power exponential, among others, offers a more flexible framework for modelling asset prices or returns. In order to analyze the sensibility to possible outliers and/or atypical returns of the maximum likelihood estimators, the local influence method was implemented. The results are illustrated by using a set of shares from companies who trade in the Chilean Stock Market. Our main conclusion is that symmetric distributions having heavier tails than those of the normal distribution, especially the t distribution with small degrees of freedom, show a better fit and allow the reduction of the influence of atypical returns in the maximum likelihood estimators.
