Hierarchie und Entlohnung

In this paper, we suggest a wage scheme that accounts for the hierarchical structure of an enterprise. We employ concepts of cooperative game theory and modify the van den Brink (2008) approach. Besides results on how the hierarchy affects wage differentials between levels of the hierarchy, we deal with the allocation of employees to the different levels.     

Conditioning Capacities and Choquet Integrals: The Role of Comonotony

Choquet integrals and capacities play a crucial role in modern decision theory. Comonotony is a central concept for these theories because the main property of a Choquet integral is its additivity for comonotone functions. We consider a Choquet integral representation of preferences showing uncertainty aversion (pessimism) and propose axioms on time consistency which yield a candidate for conditional Choquet integrals. An other axiom characterizes the role of comonotony in the use of information. We obtain two conditioning rules for capacities which amount to the well-known Bayes' and Dempster–Schafer's updating rules. We are allowed to interpret both of them as a lack of confidence in information in a dynamic extension of pessimism. This revised version was published online in June 2006 with corrections to the Cover Date.     

Welfare, labor supply and heterogeneous preferences: evidence for Europe and the US

Following the report of the Stiglitz Commission, measuring and comparing well-being across countries has gained renewed interest. Yet, analyses that go beyond income and incorporate non-market dimensions of welfare most often rely on the assumption of identical preferences to avoid the difficulties related to interpersonal comparisons. In this paper, we suggest an international comparison based on individual welfare rankings that fully retain preference heterogeneity. Focusing on the consumption-leisure trade-off, we estimate discrete choice labor supply models using harmonized microdata for 11 European countries and the US. We retrieve preference heterogeneity within and across countries and analyze several welfare criteria which take into account that differences in income are partly due to differences in tastes. The resulting welfare rankings clearly depend on the normative treatment of preference heterogeneity with alternative metrics. We show that these differences can indeed be explained by estimated preference heterogeneity across countries—rather than demographic composition.

This research focuses on insiders’ views of marital sex and their dyadic patterning. The analyses were conducted based on seventy‐two (72) couples’ assessments of their recent sexual interactions. Non‐genital and genital activities were assessed as a function of the respondents’ and the actors’ gender, and as a function of constructs that were specific to the marital partners as individuals and as a marital dyad. Consistent differences were found between husbands’ and wives’ perceptions of discrepancies within their couple. Regardless of respondents’ gender, couples reported that wives were genitally less active than husbands and that this was in accordance with the wives’ preferences. The results are discussed with respect to the advantages of using a dyadic methodology for measuring dimensions of sex which involve interpersonal behaviors.     

Towards a Sociocultural Perspective on Identity Formation in Education

This article discusses a sociocultural approach to processes of identity that has implications for how we understand learning and identity formation in education. Focusing on the socially constructed and culturally figured nature of language, tools, and interactions in learning contexts, this approach assists in the appreciation of how students navigate through and develop an understanding of themselves in different educational contexts. To this end, reference is made to Wortham's work on interactional positioning in narratives and the work of Holland and colleagues on figured worlds. Wortham provides the tools for a systematic analysis of how individuals construct their identities by positioning themselves in discursive interaction. Holland and colleagues alert us to the cultural shaping of such positioning in cultural worlds and the artifacts mediating identity formation. To explore the potential of combining these lenses, a case study is described involving a series of interviews with medical students about their self-perceptions in two contexts of clinical training. The case study highlights how different worlds and identities are formed in these educational contexts.     

Comparative assessment of analytical approaches to quantify the risk for introduction of rare animal diseases: the example of avian influenza in Spain

Trade of animals and animal products imposes an uncertain and variable risk for exotic animal diseases introduction into importing countries. Risk analysis provides importing countries with an objective, transparent, and internationally accepted method for assessing that risk. Over the last decades, European Union countries have conducted probabilistic risk assessments quite frequently to quantify the risk for rare animal diseases introduction into their territories. Most probabilistic animal health risk assessments have been typically classified into one-level and multilevel binomial models. One-level models are more simple than multilevel models because they assume that animals or products originate from one single population. However, it is unknown whether such simplification may result in substantially different results compared to those obtained through the use of multilevel models. Here, data used on a probabilistic multilevel binomial model formulated to assess the risk for highly pathogenic avian influenza introduction into Spain were reanalyzed using a one-level binomial model and their outcomes were compared. An alternative ordinal model is also proposed here, which makes use of simpler assumptions and less information compared to those required by traditional one-level and multilevel approaches. Results suggest that, at least under certain circumstances, results of the one-level and ordinal approaches are similar to those obtained using multilevel models. Consequently, we argue that, when data are insufficient to run traditional probabilistic models, the ordinal approach presented here may be a suitable alternative to rank exporting countries in terms of the risk that they impose for the spread of rare animal diseases into disease-free countries.     

Emotional Empathy and Facial Feedback

We studied if emotional empathy is related to sensitivity to facial feedback. The participants, 112 students, rated themselves on the questionnaire measure of emotional empathy (QMEE) and were divided into one high and one low empathic group. Facial expressions were manipulated to produce a happy or a sulky expression. During the manipulation, participants rated humorous films with respect to funniness. These ratings were the dependent variable. No main effect of facial expression was found. However, a significant interaction between empathy and condition indicated that the high as compared to the low empathic group rated the films as being funnier in a happy condition and a tendency to be less funny in a sulky condition. On the basis of the present results we suggest emotional empathy to be one important and previously ignored factor to explain individual differences in effects of facial feedback.     

Auswirkungen der deutschen Unternehmensteuerreform 2008 und der österreichischen Gruppenbesteuerung auf den grenzüberschreitenden Unternehmenserwerb

Using a simple model under certainty we show the implications of the new group relief system in Austria effective from 2005 and the reform act of business taxation 2008 in Germany on cross border marginal purchase prices and marginal seller prices concerning incorporations. The results show that the new group relief in Austria does not imply a higher marginal purchase price for a subsidiary located in Austria by an Austrian investor in comparison to his German competitor. If the German reform act of business taxation 2008 is not taken into account a German investor is able to pay higher marginal prices at the Austrian and German transaction market for companies. Considering the German tax reform act the situation changes. Now the Austrian investor is able to pay higher marginal prices for subsidiaries located in Germany and Austria.
