Representation of effectivity functions in coalition proof Nash equilibrium: A complete characterization

The concept of coalition proof Nash equilibrium was introduced by Bernheim et al. [5]. In the present paper, we consider the representation problem for coalition proof Nash equilibrium: For a given effectivity function, describing the power structure or the system of rights of coalitions in society, it is investigated whether there is a game form which gives rise to this effectivity function and which is such that for any preference assignment, there is a coalition proof Nash equilibrium.  It is shown that the effectivity functions which can be represented in coalition proof Nash equilibrium are exactly those which satisfy the well-known properties of maximality and superadditivity. As a corollary of the result, we obtain necessary conditions for implementation of a social choice correspondence in coalition proof Nash equilibrium which can be formulated in terms of the associated effectivity function.

Speaking With and Without Words—An Analysis of Foster Children’s Expressions and Behaviors That Are Suggestive of Prior Sexual Abuse

This exploratory study reports on foster children’s informal self-disclosures of previously unknown histories of sexual abuse. Data were collected from 40 children’s files, and an inductive thematic analysis of verbal and behavioral expressions was conducted. Findings suggest that foster children’s self-disclosures can be fragmented, spontaneous, narrative, or triggered and often occur during everyday activities in the foster family. The children disclose their past by referring to the perpetrator or the severity of the abuse or by acting out, mostly by reenacting sexual abuse experiences. In addition, some children use childish vocabulary focusing on genitals or sexual acts they were involved in or want to be involved in. Last, some foster children seem to be linguistically challenged to disclose that a female person abused them or that they were forced to reciprocate sexually. This study adds to the understanding of the complex process of child sexual abuse disclosure in the context of foster care.

INTRODUCTION TO THE SYMPOSIUM ON CONTEMPORARY BANKING RESEARCH: THE USE OF FIXED EFFECTS TO DISENTANGLE LOAN DEMAND FROM LOAN SUPPLY

With the onset of the financial crisis, disentangling the effects of loan demand and supply in contemporary banking research has become vital for a proper assessment of supply-related banking shocks. These shocks may negatively affect the real economy through many channels, such as the lending channel of monetary policy transmission, the bank risk-taking channel or the evaluation of macroprudential policy efficiency. All these rely on separating the two lending components. Empirical identification has largely relied on the use of demand-related fixed effects, which has also been applied in several analyses within this symposium. (JEL G21)     

Six of One and Half a Dozen of the Other: The Gender Subtext of Taylorism and Team-based Work

This article analyses gendering processes in two distinct models of work organization. It is a widespread belief that, compared to hierarchical (Tayloristic) organizations, team-based work offers opportunities for a high quality of working life to a broader range of employees, both men and women. Our research, however, suggests that gender inequality is (re)produced in both settings and results from the so-called gender subtext. The gender subtext is the set of often concealed power-based processes (re)producing gender distinction in social practices through organizational and individual arrangements. We draw a comparison between the gender subtext of Tayloristic and team-based work organizations through a theoretical analysis, illustrated by empirical data concerning the functioning of the gender subtext in organizations in the Dutch banking sector. Taylorism and team-based work differ in their conceptualization of organization and job design, but, when it comes to the gender subtext, it is six of one and half a dozen of the other. We argue that in both approaches a gender subtext contributes to the emergence of different but gendered notions of the ‘disembodied worker’. In both cases the notion of the abstract worker is implicitly loaded with masculine connotations. This gender bias is supported by two factors influencing the gendering of jobs: the gender connotations of care responsibilities and of qualification profiles. These implicit connotations produce and reinforce unequal opportunities for men and women to get highly qualified or management jobs. Our research, therefore, questions the self-evidence of stating that team-based work will offer opportunities for a higher quality of working life for women.     

Bayesian predictive power: choice of prior and some recommendations for its use as probability of success in drug development

Bayesian predictive power, the expectation of the power function with respect to a prior distribution for the true underlying effect size, is routinely used in drug development to quantify the probability of success of a clinical trial. Choosing the prior is crucial for the properties and interpretability of Bayesian predictive power. We review recommendations on the choice of prior for Bayesian predictive power and explore its features as a function of the prior. The density of power values induced by a given prior is derived analytically and its shape characterized. We find that for a typical clinical trial scenario, this density has a u‐shape very similar, but not equal, to a β‐distribution. Alternative priors are discussed, and practical recommendations to assess the sensitivity of Bayesian predictive power to its input parameters are provided.

Spillover Between Work and Home,Role Importance and Life Satisfaction

This study of n = 201 knowledge workers examines positive and negative spillover between work and home and its interrelation with life satisfaction. Additionally, it accounts for the direct effect of role importance on life satisfaction and its moderating effect on the interrelation between spillover and life satisfaction. Central to role importance is the degree of attachment that an individual places on family role and career role. Positive spillover from home is interrelated with higher life satisfaction, whereas negative spillover from work is related to lower life satisfaction. Family role importance and career role importance are associated with higher life satisfaction. For respondents with higher family role importance, there is a stronger interrelation between negative spillover from home and lower life satisfaction.     

A new index of perceived inflation: Assumptions, method, and application to Germany

After the introduction of Euro notes and coins in January 2002, throughout the Economic and Monetary Union member countries a substantial discrepancy was evident between inflation as measured by the official consumer price indices (CPI) and that perceived by the general public. The starting point of this paper is the German case. First, the public controversy in Germany after the Euro changeover is sketched. Then conventional approaches to perceived inflation are reviewed including the many studies published by the German Federal Statistical Office as well as the perceived inflation balance generated within the EU Consumer Survey. In the main part of the paper, a novel approach to measuring perceived inflation is developed, the Index of Perceived Inflation (IPI). First, the hypotheses underlying this index are presented. Then, the IPI is derived. In the forth section the IPI is applied to the German data. The IPI time series for Germany from 1996 through 2005 shows a particularly high perceived inflation around the introduction of Euro notes and coins. In the fifth section the hypotheses of inflation perception underlying the IPI are critically reviewed. The paper closes with a conclusion on the insights gained through computation of the IPI.     

Competition of politicians for wages and office

We examine a model in which two politicians compete for office and for wages. Their remunerations are either set by the public or are offered competitively by the candidates during campaigns. Our main finding shows that competitive wage offers by candidates lead to lower social welfare than remunerations predetermined by the public, since wage competition may lead to higher wage costs or to the election of less competent candidates.
