Applied social reporting: A social indicators system for West German Society

This paper presents a ‘system’, i.e. systematic compilation, of about 200 social indicators in 10 areas of life, for the Federal Republic of Germany, 1955–1975. The construction of this indicator system is explained and an abridged version is introduced that can be comprised into one master table. Next, an overall evaluation of welfare development in West Germany is given and four models for a time-sequence interpretation are discussed. Finally, the present effort is put in perspective, e.g. in regard of the OECD program and of recent quality-of-life survey research.     

Random Choice as Behavioral Optimization

We develop an extension of Luce's random choice model to study violations of the weak axiom of revealed preference. We introduce the notion of a stochastic preference and show that it implies the Luce model. Then, to address well‐known difficulties of the Luce model, we define the attribute rule and establish that the existence of a well‐defined stochastic preference over attributes characterizes it. We prove that the set of attribute rules and random utility maximizers are essentially the same. Finally, we show that both the Luce and attribute rules have a unique consistent extension to dynamic problems.     

Selbstmanagement-Entwicklung durch coaching?

Development of self-management by coaching? An expert survey on the promotion of self-management competenciesThe much-discussed assumption that business coaching promotes clients’ self-management competence was explored through an expert survey. In a qualitative questionnaire study, 20 professional coaches provided information on their conceptual understanding of self-management, their approaches to promoting client self-management and on strategies employed to assess intervention outcome. In addition, coaches specified the obstacles and constraints clients encounter when transferring improved self-management skills into everyday working life. The results corroborate the relevance of the self-management concept in a coaching context. The benefits resulting from an increased consideration of self-management processes in coaching research, vocational training courses and day-to-day coaching practice are discussed. The use of theoretical concepts which provide a guideline is recommended.     

Real estate and real estate finance as a research field—an international overview

We present a citation-based analysis of the most important journals on real estate and real estate finance over a time period from 1986 to 2010. For each year, those three articles with the highest number of citations according to Google Scholar are identified. A thorough analysis of all 75 selected articles reveals that the focus of interest has been on (1)empirical research, (2) mainly using data ofresidential real estate, with (3) the primary objective of evaluating real estateinvestment until the midst 1990s. In order to derive reliable risk-return relations for real estate investment, (4) asset pricing as the main task of real estateappraisal is in the centre of attention, too. Appraisal issues have relatively gained importance for the last fifteen years in comparison to investment issues. Interdisciplinary aspects and sustainable issues are only very rarely integrated in appraisal methods, the focus is primarily on maximizing economic returns. Therefore, our citation analysis confirms that the Financial Management Approach of Dasso and Woodward (1980) is the predominant approach particularly in the United States. Our findings regarding our basic sample of articles are cross-checked by several robustness tests. For future research activities, it seems to be quite promising to focus on the one hand on interdisciplinary aspects and on the other hand to contribute to the theoretical foundation of real estate with the aim of developing a common body of knowledge.     

An empirical likelihood goodness-of-fit test for time series

Summary. Standard goodness-of-fit tests for a parametric regression model against a series of nonparametric alternatives are based on residuals arising from a fitted model. When a parametric regression model is compared with a nonparametric model, goodness-of-fit testing can be naturally approached by evaluating the likelihood of the parametric model within a nonparametric framework. We employ the empirical likelihood for an α -mixing process to formulate a test statistic that measures the goodness of fit of a parametric regression model. The technique is based on a comparison with kernel smoothing estimators. The empirical likelihood formulation of the test has two attractive features. One is its automatic consideration of the variation that is associated with the nonparametric fit due to empirical likelihood's ability to Studentize internally. The other is that the asymptotic distribution of the test statistic is free of unknown parameters, avoiding plug-in estimation. We apply the test to a discretized diffusion model which has recently been considered in financial market analysis.     

Struktur und Beziehung in gruppalen Settings

Structure and relationship in group settings Working in and with groups involves always working with the relationships between the group members, even when it is not intended to influence them. The individual interactions within the group tend to develop enduring patterns, which may provide important resources of realization of the group objects, but also strong resistances. A knowledge of the inherent regularities of the communication and role structures and of the development of relationships represents an essential competence in working effectively with groups and teams.     

A Population Policy Rationale for the Twenty‐First Century

I propose that the primary goal of twenty‐first‐century population policies should be to strengthen the human resource base for national and global sustainable development. I discuss the shortcomings of the three dominant twentieth‐century population policy rationales: acceptance of replacement‐level fertility as a demographic goal; realizing a “demographic dividend” from the changing age structure; and filling the “unmet need” for family planning. I demonstrate that in all three cases the explicit incorporation of education into the model changes the picture and makes female education a key population policy priority. Population policies under this new rationale could be viewed as public human resource management. I argue that 20 years after the Cairo ICPD the international community needs a new rationale for population policies in the context of sustainable development and that a focus on human capital development, in particular education and health, is the most promising approach.     

What difference do alternative immigration and integration levels make to Western Europe?

The population of Western Europe (EC plus EFTA) is seen as consisting of three sub-populations: the natives, the East-European immigrants, and the non-European immigrants. Different immigration levels assumed add to the non-native populations while different levels of integration describe the transition intensities from a non-native to a native category. Alternative multi-state population projections to 2050 based on six scenarios show that (1) in the case of no further immigration the total population of Western Europe will start to decline after 2010; (2) the rate of integration influences the future size of the non-European population much more than alternative levels of immigration; (3) in the long run the Eastern Europeans will be quantitatively insignificant; (4) the Western European population is bound to significant population aging no matter what happens with immigration; and (5) in the short to medium run immigrants contribute to the alleviation of the pension burden.La population d'Europe occidentale (CE et AELE) est décomposée en trois sous-populations: les natifs, les immigrants originaires d'Europe de l'Est, et les immigrants originaires du reste du monde. Les populations non-natives augmentent sous l'effet de divers niveaux d'immigration tandis que les intensités de passage d'une catégorie non-native à native sont décrites par différents niveaux d' intégration. Des projections de population jusqu'en 2050 dans ces divers états, basées sur six scénarios, montrent que: (1) la population totale de l'Europe occidentale commencerait à baisser après 2010, dans le cas d'un arrêt de l'immigration; (2) le taux d' intégration influencerait la taille future de la population non-européenne beaucoup plus fortement que le niveau d'immigration; (3) dans le long terme, les Européens de l'Est serait en nombre très réduit; (4) la population d'Europe occidentale connaîtra un vieillissement important de sa population, quelque soit ses flux d'immigrants; et (5) dans le court et le moyen terme les immigrants contribueraient à alléger le poids des retraites.
