Pension Schemes Comparison between EEC Countries*

Abstract. A lot of research has been made on macroeconomic spending on the financing of retirement, most of it taking into account demographic evolution. On the other hand, little research has gone into international comparisons that shed more light on the standards of living that are guaranteed after retirement, and on the flexibility and accessibility of public pension schemes. It is a study of this type that we have carried out for 11 member-states of the EEC (Greece having been left out because of its lack of statistics). In this article, we construct an index that reflects the levels of protection that are offered to the aged by the “first pillar” and under the most general conditions. On the basis of a series of important criteria (conditions for access, flexibility, intervention levels, etc.), we calculated an average of the scores for each criterion. These averages are then used to obtain a general score for each country, ranking them against each other relative to the quality of their respective pension schemes.     

Propensity of Canada's Foreign‐born to Claim Unemployment Insurance Benefits

This article examines the relationship between claiming unemployment insurance benefits in Canada and the immigrant class under which immigrants were admitted (namely skilled workers, assisted relatives, family class, refugees), using a new data set that combines income tax and immigration records. Claims rates (or the proportion of immigrants who claimed unemployment insurance benefits) are calculated for each immigrant landing class for the cohorts of immigrants who landed in 1980, 1985 and 1989; for each cohort, annual claims rates are presented from the year after landing to 1995. The claims rates indicate that there are significant differences among the different immigrant landing classes: those admitted as skilled workers have relatively low claims rates, those in the family class or assisted relatives have higher rates, and refugees have the highest rates. For all immigrant landing classes, claims rates rise rapidly during the two or three years after arrival in Canada, but decline thereafter for all classes. Differences in claims rates on unemployment insurance benefits remain across the immigrant landing classes after general economic conditions and some characteristics of the immigrants are controlled.     

Cross-disciplinary problem-solving workshop: a pedagogical approach to anticipate ergonomist engineering design collaboration

The aims of this paper are to present concept and results of an innovative educational model approach based on ergonomics involvement in industrial project. First we present Cross disciplinary Problem solving Workshop by answering three questions:1) What is a CPW: A partnership between Universities and one or several companies, purposes of it are first to increase health, well being, companies teams competencies, and competitiveness, second to train the "IPOD generation" to include risks prevention in design. 2) How does it work? CPW allows cooperation between experience and new insight through inductive methods. This model follows the Piaget (1) philosophy linking concrete world to abstraction by a learning system associating realization and abstraction. 3) Is it successful? In order to answer this third question we will show examples of studies and models performed during CPWs.It appears that the CPWs produce visible results in companies such as new process designs, new methods, and also changes in lectures. However some less visible results remain unclear: How the company personnel evolve during and after CPW? Does CPW motivate our future engineers enough to continuously improve their skills in risk prevention and innovative design?     

Sensitivity to Social Contingency and Positive Emotion in 2‐Month‐Olds

This study was aimed at sorting out conflicting results in the literature concerning 2‐month‐olds' sensitivity to interpersonal contingency, and investigated the potential role of infants' positive emotion in contingency detection. Infants were randomly assigned to an experimental group (EG) that was presented an uninterrupted live–replay–live sequence of three 30‐sec episodes of their mothers' communicative behavior using a double video TV paradigm, or to a control group (CG) that was presented an uninterrupted 90 sec of contingent maternal interactions. Infants of the EG grimaced more than infants of the CG only during the 2nd period of social exchange (replay vs. 2nd live period), but there was an increase of grimacing and a reduction in gazing during the 3rd period of televised interactions in infants of the CG. Each group was split into 2 subgroups a posteriori according to the presence or absence of smiling during the 1st contingent episode. Smiling infants of the EG reacted more negatively during the 2nd interaction period compared to other subgroups. These findings support the view that sensitivity, not fatigue or loss of interest to maternal stimulation, accounts for 2‐month‐olds' expressive changes during noncontingent maternal interactions; fatigue or loss of interest better explains the decline in attention and the increase of negative expressiveness during the last period of contingent interaction. The findings also suggest that the emotional climate of dyadic exchanges could be a contributing factor to infants' ability to detect the relations between their own actions and those of their social partners.     

Divorce and the duality of marital payoff

Empirical studies on the determinants of divorce are scarce in economics. The literature has focused on the impact of income differentials between partners. We extend the model of marital dissolution to integrate time-varying non-pecuniary quality of the match. We use a unique Russian dataset to measure shocks to the non-economic components of the value of marriage. Our estimates suggest that the monetary and non-monetary components enter additively into marriage surplus, but with gender-specific marginal rates of substitution: divorce hazard is more sensitive to the non-pecuniary dissatisfaction of the wife than to that of the husband; impacts of the monetary components are also gender-specific and highly non-linear. We link these findings to remarriage prospects and partial risk sharing.     

Bayesian Causality

Abstract

Although no universally accepted definition of causality exists, in practice one is often faced with the question of statistically assessing causal relationships in different settings. We present a uniform general approach to causality problems derived from the axiomatic foundations of the Bayesian statistical framework. In this approach, causality statements are viewed as hypotheses, or models, about the world and the fundamental object to be computed is the posterior distribution of the causal hypotheses, given the data and the background knowledge. Computation of the posterior, illustrated here in simple examples, may involve complex probabilistic modeling but this is no different than in any other Bayesian modeling situation. The main advantage of the approach is its connection to the axiomatic foundations of the Bayesian framework, and the general uniformity with which it can be applied to a variety of causality settings, ranging from specific to general cases, or from causes of effects to effects of causes.
