Equality preference in the claims problem: a questionnaire study of cuts in earnings and pensions

Many distributional conflicts are characterized by the presence of acquired rights. The basic structure of these conflicts is that of the so-called claims problem, in which an amount of money has to be divided among individuals with differing claims and the total amount available falls short of the sum of the claims. We describe the results of a questionnaire in which Belgian and German students were confronted with nine claims problems. In the “Firm” version, respondents had to divide revenue among the owners of a firm who contribute to the activities of the firm in different degrees. In the “Pensions” version, they had to divide tax money among pensioners who have paid different contributions during their active career. Responses in the Pensions version are more egalitarian than in the Firm version. For both versions, the proportional rule performs very well in describing the choices of the respondents. Other prominent rules—in particular the constrained equal awards and constrained equal losses rules—fail to capture some basic intuitions. A substantial part of the respondents tend to become more progressive as the amount to be distributed decreases other things equal, and tend to become more progressive as the inequality in the distribution of claims becomes more unequal other things equal. All of these conclusions are robust with respect to the difference in home-country of the respondents.     

A comparison of early retirement pensions in the United States and Russia: the pensions of musicians

Early retirement pensions for particular occupations free national policy to establish the social security early retirement age at a later age that is more appropriate for the population as a whole. This paper focuses on early retirement pensions in the United States and the Russian Federation. While comparing early retirement pensions generally, the paper provides a more detailed discussion of the pensions for musicians. While this is an unconventional group to choose for the study of pensions, study of their pensions yields insights into the principles underlying retirement age policy in the two countries.     

Complementarity of pensions and training under multiemployer plans

We compare firmoptimizing and institutional models of labor contracts to investigate how different types of pension plans affect employee training. Unlike previous stud-ies, we consider an expanded voice model of training and pension coverage in which worker and union preferences feed back on firm decisions, and we test for this bidi-rectional causality between pensions and training. A standard view is that firms pro-vide pensions to optimize their training costs. However, when pension coverage is treated as endogenous in a twostage least squares regression (the data are merged 1991 CPS samples), pensions have a negative effect on training. In contrast, when the pension is a definedbenefit, multiemployer plan, training and pensions are comple-ments, consistent with both optimizing and institutional models. We are grateful for excellent research assistance from Michael Ash, Bhashkar Mazumder, and Judith Ruha and for suggestions from Dale Belman, David Card, B.J. Lee, David MacPherson, and John Turner.     

An overview of work, retirement, and pensions in Japan

Work to retirement in Japan is a sequential transition for the most part, and Japan permits mandatory retirement by firms at age 60. But many older people work beyond the age of 60, many more than in other industrialized countries. A number of hypotheses are examined, having to do with pensions, health, opportunity, interest in working, cultural attitudes (including the concept of ikigai), and public policy initiatives (such as employment policy and the Silver Human Resource Centers). Japan's cultural attitudes and existing policies appear to have set Japan on a unique course in considering the aging of its population. To what extent should other nations emulate Japan?     

How technology affects the design and administration of pensions and benefits

Conclusion Technology presents opportunities in all areas of employee benefits — design, administration, and communication. Indeed, it holds out the potential to deliver benefits, like almost every other product or service, in a way that is “better, faster, cheaper.” But achieving that goal will involve substantial financial investment and many hours of staff time.     

Gender inequalities in pensions: different components similar levels of dispersion

While the average gender gap in pensions is quite well documented, gender differences in the distribution of pensions have rarely been explored. We show in this paper that pension dispersion is very similar for men and women within the French pension system of a given sector (public or private). Gender differences are less marked among retired civil servants than among former private sector employees. However, the determinants of these inequalities are not the same for men and women. Using a regression-based decomposition of the Gini coefficient, we find that pension dispersion is mostly due to dispersion of the reference wage for all retirees but gender differences exist. For women, in particular, pension dispersion is also due to the dispersion in contribution periods. We also decompose the Gini coefficient by source of pension to measure the impact of institutional rules (minimum pensions, survivor’s pension) on the extent of pension inequality. Unexpectedly, we find that the impact of minimum pensions is limited, although slightly larger for civil servants than for private-sector employees. Survivor’s pension schemes, on the other hand, contribute positively to pension dispersion among retired women.     

Réformes des retraites et pensions en Malaisie

Les auteurs font le point sur les problèmes que connaissent les régimes de retraite et sur la réforme des pensions en Malaisie. Les modèles proposés par le Bureau international du Travail, la Banque mondiale et l'Association de Genève sont analysés et comparés, ce qui fournit un cadre conceptuel pour la mise en place et la réforme des régimes en question. Ce cadre est utilisé pour évaluer la réforme des pensions en Malaisie, avec ses avantages et ses inconvénients pour les travailleurs. Les auteurs concluent en proposant un certain nombre de recommandations en matière de régimes de retraite.     

Family history and pensions: The relationships between marriage,divorce, children,and private pension coverage

This article examines how family history affects the odds of private pension receipt and how these effects vary by sex. Analyses indicated that family history had opposite effects for men and women. Compared to continuously married men, men who were single or divorced had lower odds of pension receipt; having children was associated with higher odds. For women, being single or divorced was associated with higher odds of pension receipt, and having children decreased their odds. After reanalyzing the effects of family history in the context of couples' joint pension receipt, the negative association between pension receipt and children becomes insignificant for women, and being single, divorced, or widowed has negative effects for both men and women. These results suggest that if individuals stay together as a couple, they increase their chances of access to a pension and financial well-being during retirement.     

The inverse Banzhaf problem

Let ${\mathcal{F}}Let F{\mathcal{F}} be a family of subsets of the ground set [n] = {1, 2, . . . , n}. For each i ? [n]{i \in [n]} we let p(F,i){p(\mathcal{F},i)} be the number of pairs of subsets that differ in the element i and exactly one of them is in F{\mathcal{F}}. We interpret p(F,i){p(\mathcal{F},i)} as the influence of that element. The normalized Banzhaf vector of F{\mathcal{F}}, denoted B(F){B(\mathcal{F})}, is the vector (B(F,1),...,B(F,n)){(B(\mathcal{F},1),\dots,B(\mathcal{F},n))}, where B(F,i)=\fracp(F,i)p(F){B(\mathcal{F},i)=\frac{p(\mathcal{F},i)}{p(\mathcal{F})}} and p(F){p(\mathcal{F})} is the sum of all p(F,i){p(\mathcal{F},i)}. The Banzhaf vector has been studied in the context of measuring voting power in voting games as well as in Boolean circuit theory. In this paper we investigate which non-negative vectors of sum 1 can be closely approximated by Banzhaf vectors of simple voting games. In particular, we show that if a vector has most of its weight concentrated in k < n coordinates, then it must be essentially the Banzhaf vector of some simple voting game with n − k dummy voters.     

The traveling group problem

This paper combines social choice theory with mathematical optimization by applying various group decision concepts to a classical problem of combinatorial optimization, namely the famous traveling salesperson (salesman) problem. The aim of the latter is to find a tour through all vertices of a given graph along edges of minimal total cost. In this contribution we replace the measure of additive edge costs by the social acceptance of different edges and the resulting tours. In particular, for four different voting rules, the Borda rule, Approval voting, Plurality rule and Simple Majority rule, we will investigate the social acceptance of tours derived from global and local decisions. It will be shown that these two decision approaches can lead to widely varying results.     

The problem of early English sociology

A brief survey is attempted of the recent literature relating to the ‘problem’ of early English sociology, i.e. its apparent failure to produce in the late nineteenth and early twentieth centuries a body of thought comparable to the ‘classical’ sociological tradition which emerged in France and Germany during the same period. It is argued that the absence of such a tradition in England cannot be linked to the supposed failure of the English middle class to develop a corporate identity, as certain contemporary Marxist theorists have suggested. If the continental ‘classical’ tradition reflects the ideology of any social stratum, it is that of the educated middle class, linked to the central state apparatus, which developed in a number of European countries during the nineteenth century. The failure of such an intelligentsia to emerge in England in the same period is reflected in the specific development of English social thought.     

A note on pensions and firm performance: First evidence from german micro data

Using a large new data set we present results from the first econometric study of the effects of pensions on firm performance in Germany. We find evidence for positive effects on wages, reduction of labor turnover, training, and profits. We use data from the Hannover Firm Panel Study which was financially supported by the Volkswagen Foundation.
