Downscaling,Upgrading or Linking? Ways to Realize Micro‐Insurance

Micro‐insurance is seen by many as a promising tool to improve the social protection of low‐income earners. This assumption is supported by the positive experience of existing micro‐insurance schemes. At the same time, however, many schemes have failed to organize sustainable insurance arrangements that are affordable for the poor and near‐poor. The question is thus which institutions are best able to arrange for micro‐insurance. Formal institutions such as public agencies or commercial companies are usually too distant in social and spatial terms from the target group of micro‐insurance and face severe difficulties in downscaling. Informal institutions, however, such as self‐help groups or grassroots NGOs, usually lack the know‐how, experience and capacities to design and manage insurance arrangements. They need powerful partners to upgrade. An alternative would be that formal and informal institutions cooperate in providing micro‐insurance. This article argues that such a linking approach is superior to both the downscaling and upgrading approach.     

Trajectories of body mass and self-concept in black and white girls: the lingering effects of stigma

As a stigmatizing condition, obesity may lead to the internalization of devalued labels and threats to self-concept. Modified labeling theory suggests that the effects of stigma may outlive direct manifestations of the discredited characteristic itself. This article considers whether obesity's effects on self-concept linger when obese youth enter the normal body mass range. Using longitudinal data from the National Growth and Health Study on 2,206 black and white girls, we estimated a parallel-process growth mixture model of body mass linked to growth models of body image discrepancy and self-esteem. We found that discrepancy was higher and self-esteem lower in formerly obese girls compared to girls always in the normal range and comparable to chronically obese girls. Neither body image discrepancy nor self-esteem rebounded in white girls despite reduction in body mass, suggesting that the effects of stigma linger. Self-esteem, but not discrepancy, did rebound in black girls.     

The influence of world societal forces on social tolerance. A time comparative study of prejudices in 32 countries

Societal variation in xenophobia, homophobia, and other prejudices is frequently explained by the economic background and political history of different countries. This article expands these explanations by considering the influence of world societal factors on individual attitudes. The empirical analysis is based on survey data collected within the World Value Survey and European Values Study framework between 1989 and 2010. Data are combined to a three-wave cross-sectional design including about 130,000 respondents from 32 countries. Results show that xenophobia and homophobia are influenced by the national political history, societal affluence, and the presence of international organizations. Global forces, however, are of particular importance for homophobia.     

Equality of opportunity and the distribution of long-run income in Sweden

Equality of opportunity is an ethical goal with almost universal appeal. The interpretation taken here is that a society has achieved equality of opportunity if it is the case that what individuals accomplish, with respect to some desirable objective, is determined wholly by their choices and personal effort, rather than by circumstances beyond their control. We use data for Swedish men born between 1955 and 1967 for whom we measure the distribution of long-run income, as well as several important background circumstances, such as parental education and income, family structure and own IQ before adulthood. We address the question: in Sweden, given its present constellation of social policies and institutions, to what extent is existing income inequality due to circumstances, as opposed to ‘effort’? Our results suggest that several circumstances, importantly both parental income and own IQ, are important for long-run income inequality, but that variations in individual effort account for the most part of that inequality.     

Mein(schöner)Prof.de

Evaluations of academic teaching have become an instrument for the quality management in universities of constantly growing importance. This process is unproblematic as long as the quality of teaching is rated validly by the evaluations of students. The validity of the rating, however, becomes questionable as an influence of the teaching staffs’ physical attractiveness on the evaluation of teaching has been proved. This effect would only be compatible with an assumed valid rating of the teaching performance if attractive teachers would in fact show a better performance in academic teaching and are not just better rated for their attractiveness. We analyzed data from the German online platform MeinProf.de for the evaluation of academic teachers. The results show that attractive teachers very probably do not perform better. The attractiveness of female teachers does not have the expected influence on the evaluation of their teaching.     

Wage Dynamics and Unemployment in Germany: Evidence from Regional Panel Data

A stylized fact of empirical work on the relationship of wages and unemployment using macro data for European countries is a combination of strong autocorrelation of wages and a significant negative long‐run relationship of wages and unemployment. However, this view is challenged by empirical work relying on regional or micro data providing evidence for an instantaneous adjustment of wages to variations in the level of unemployment. Exploiting regional panel data for West Germany, we show that, at least for the years 1990–94, regional and macro data mirror the same phenomenon. Our results are broadly consistent with the observed increase in the natural rate of unemployment in Germany.     

The role of cognitive load in effective strategic issue management

Firms have different ways of addressing issues emerging from outside their regular calendar-driven strategy processes. These practices tend to be unstructured, organization specific, and highly dependent on the characteristics of the strategic issues themselves. Building on three dimensions of cognitive load—intrinsic, germane, and extraneous cognitive load—we extend existing research on strategic issue management by showing how different team-level choices in strategic issue processing and organizational congestion interact in their effects on a firm's strategic issue management performance. Based on an in-depth analysis of all 92 strategic issue decisions in a large multinational firm during a three-year period, we find that organizational disturbances influence strategic issue initiation by top management, which in turn influences the quality of strategic issue management practices and subsequent performance outcomes. We conclude by providing recommendations for managers on how they can decrease the sensitivity of their companies' strategic issue systems to external disturbances.     

A small sample estimator for a polynomial regression with errors in the variables

An adjusted least squares estimator, introduced by Cheng and Schneeweiss for consistently estimating a polynomial regression of any degree with errors in the variables, is modified such that it shows good results in small samples without losing its asymptotic properties for large samples. Simulation studies corroborate the theoretical findings.
