One of the most important controversies in the health economics discourse of the last twenty years concerns the question whether the imminent ageing of the population in most OECD countries will place an additional burden on the tax-payers who finance public health care systems. These systems are usually pay-as-you-go financed with taxes or contributions depending on labor income and pensions. Population ageing due to rising longevity and below-replacement fertility in coming decades will lower the population share of working-age persons and raise the share of pensioners. Since labor income exceeds pensions by far, this will weaken the tax base so that tax or contribution rates will rise notably.

The COVID-19 pandemic has drastically changed many aspects of our society and work life. This study assesses how daily variations in employees' work engagement are affected by daily variations in infection rates in employees' communities. Applying the conceptual framework of event system theory, we argue that surging COVID-19 cases have an impact on employee engagement, depending on the individual sensemaking processes of the pandemic. We assume that employee age and received leader support are key context factors for these sensemaking processes and that particularly older employees and employees who receive little leader consideration react with lower work engagement levels toward rising local COVID-19 infections in their proximity. We find support for most of our proposed relationships in an 8-day diary study of German employees, which we integrate with official COVID-19 case statistics on the county level. We discuss the implications of these results for the literature on extreme events and individual workplace behavior. Furthermore, these findings have important implications for companies and executives who are confronted with local COVID-19 outbreaks or other extreme societal events.

The article investigates the conditions of multiple engagement in the private and public realm in the second half of life. More specifically, I look at the relationship between informal care-giving and formal volunteering in a country-comparative way. Based on longitudinal data from the Survey of Health, Ageing and Retirement, 2004–2015, I investigate the 50+ population in 13 European countries. Controlling for unobserved heterogeneity by using conditional fixed-effect logistic regression models, I confirm earlier findings that care-givers are more likely to volunteer than non-care-givers; this effect is independent of care-giving intensity but only true for those who care outside their own household. As to macro-level influences, I find that both care-in-kind and cash-for-care expenditures increase the likelihood of volunteering among the 50+ population. The effect of cash-for-care expenditure is even stronger for the group of those who give intensive care outside their own households than for non-care-givers. Moreover, I find effects related to family's and women's role in society. First, I show a negative effect of a country's societal norm of family orientation on volunteering participation for those giving sporadic care outside their household but also among non-care-givers. Second, in countries with higher female labour market participation among the middle-aged, the volunteering likelihood is higher for sporadic female care-givers outside their own household but also among female non-care-givers.

Starting a new job is able to boost people's careers, but might come at the expense of other areas of life. To investigate individual implications of job mobility, we analyse the effects of job changes on time-use and indicators of subjective well-being using rich data from a representative German panel survey. We find that job switchers report relatively high levels of life satisfaction, at least for the first time after the job change. There is no such ‘honeymoon’ period for job changes triggered by plant closures. Instead, we find evidence for a harmful impact of involuntary mobility on family life.

It has long been overlooked that factions of finance such as banks and insurers can have opposing policy interests. This paper is concerned with the preferences and strategies of private financial actors in the context of private prefunded pensions. To capture the “tug of war” among these actors, this paper identifies their different financial business models (insurance- and investment-orientation), political roles (financial incumbents and challengers), and levels at which infighting may occur (political and product-market level). For the German case, it shows that product-market competition among financial incumbents and challengers over retirement savings products only turned into competition politics during the 1990s, when shifting political winds provided an opening to insert path-shaping instruments in line with the program of finance capitalism. Financial actors’ preferences are not a derivative of economic or functional incentives, but socially embedded in that they are crucially shaped by interactions with their competitors and the political environment. The analysis disentangles the complex web of competition, cooperation, and ownership among factions of finance and discerns their genuine preferences from those strategically adjusted to context. This sheds doubt on functionalist explanations of (pension) financialization and enhances our understanding of how financial actors form and pursue their preferences.

Based on longitudinal data from Germany, we analyze how perceptions of discrimination change once migrants’ integration evolves. Individuals who identify more strongly with the host country, speak the language, have native friends, and are adequately employed report less discrimination overall. However, group-specific analyses reveal that German-born Turks feel more rather than less discriminated against after their language skills and their identification increase. For this group, we find evidence for the “integration paradox”, i.e., the finding that better educated migrants have more rather than less negative attitudes about the host society. Results suggest that attributional processes rather than rising exposure to discrimination might be the main mechanism linking integration to higher levels of perceived discrimination. Obviously, discrimination does not disappear for groups facing salient ethnic boundaries and is met with growing awareness and sensitivity among individuals that have become more similar to the majority of members. This, in turn, by no means implies that perceived discrimination is detached from reality.

Studying the so-called refugee crisis in Germany, this article asks about the effectiveness of crisis management by a large number of local administrations, each acting upon the same crisis impulse of a high number of asylum seekers who entered the country in 2015 and 2016. Instead of theorizing the exact administrative design features fit for an effective crisis response, the focus is on the ability of administrations to adjust. We conceptualize such shifts in administrative practices as informal and temporary (latent) deviations from routine action along two dimensions of organizational behavior typically dominant in private and nonprofit sector organizations, respectively: internal flexibility and citizen participation (hybridity). Novel survey data from 235 out of 401 German district authorities are reported. We test the effects of different forms of latent hybridization on administrative effectiveness using regression modeling. Findings indicate that changes in administrative practices towards more flexible and participatory action had a positive impact on self-reported crisis management effectiveness. The effect of flexible action was especially pronounced in districts that were allocated higher shares of asylum seekers. These findings advance theory on crisis management and bottom-up implementation, highlighting the ability of local agencies to shift practices as a key explanatory factor for effective administrative action in exceptional situations.

Bureaucratic representation theory holds that civil servants are not “neutral” in a Weberian sense. Bureaucrats are thought to “actively” represent their communities by trying to make them better off. This article proposes an alternative understanding of individual behavior in representation that emphasizes knowledge sharing instead of patronage, but leads to similar outcomes: Their societal background provides officials with advanced social knowledge about the group(s) they represent, including both informational knowledge (facts about culture, history, politics) and relational knowledge (how people interact). Bureaucratic knowledge linkage is the process of sharing information and managing relations internally and with citizens. An extreme case serves to illustrate knowledge linkage empirically: Survey data from an international organization yield high levels of knowledge asymmetries within staff bodies and subsequent observation of knowledge linkage mechanisms. In generalizing findings, the risks (knowledge distortions) and benefits (attaining public value) of knowledge linkage are discussed for both international and domestic administrations.

Many educational systems are characterized by segregation between a general and vocational educational track. When adolescents must decide on their postcompulsory education at the end of lower secondary school, the different programs are typically embedded in one of these two main tracks. Prior career choice theories postulate that vocational interests, as structured by the six-dimensional RIASEC model of Holland (1997), play a crucial role in educational and vocational transition processes. However, regarding the question of general versus vocational education, previous studies have mainly focused on the effects of social background. Therefore, this paper examines the impact of vocational interests on the choice of Baccalaureate School (BAC, general track), Vocational Education and Training (VET, vocational track) or the Federal Vocational Baccalaureate (FVB), a hybrid qualification that links elements of both tracks. The sample consists of N = 609 students at the end of lower secondary school in Switzerland. The results of multinomial logistic regression analyses show that all six dimensions of Holland’s interest model are significant predictors for the three postcompulsory tracks, even when controlling for school variables (e.g., grades) and variables of social background. While the realistic and social dimensions are positively interrelated with the choice of VET, the artistic, investigative and enterprising dimensions predict the choice of BAC. The conventional dimension is the only one positively linked to the choice of FVB. The results are discussed with special attention to segregation between more practical and more theoretical types of interests.

Addressing heterogeneity in the classroom by adapting instruction to learners’ needs challenges teachers in their daily work. To provide adaptive instruction in the most flexible way, teachers face the problem of assessing students’ individual characteristics (learning prerequisites and learning needs) and situational states (learning experiences and learning progress) along with the characteristics of the learning environment. To support teachers in gathering and processing such multidimensional diagnostic information in class, we have developed a client–server based software prototype running on mobile devices: the Teachers’ Diagnostic Support System. Following the generic educational design research process, we (1) delineate theoretical implications for system requirements drawn from a literature review, (2) describe the systems’ design and technical development and (3) report the results of a usability study. We broaden our theoretical understanding of heterogeneity within school classes and establish a basis for technological interventions to improve diagnostic accuracy in adaptive instructional strategies.

Most models of word production converge on the assumption that selecting a specific word to name is a competitive process. Monolingual speakers experience lexical competition in their spoken language (i.e., within-language competition), but bilingual speakers who constantly juggle two sets of lexical items face within- and between-language competition. It has been argued that one of the reasons bilingual speakers perform poorly in linguistic tasks compared to monolinguals is the interference from the non-target language. However, this constant juggling of two languages has also been proposed to lead to better executive control abilities in bilinguals. The aim of this research was to determine the relationship between increased lexical competition as induced by semantic context manipulation in the blocked-cyclic picture naming paradigm, and executive control processes in bilingual and monolingual speakers. We implemented the blocked-cyclic picture naming paradigm to induce increased lexical competition and employed independent executive control tasks to understand its role in reducing increased lexical competition. We also computed delta plots – size of interference effects as a function of naming latencies – to investigate the type of inhibition involved in the blocked-cyclic picture naming paradigm. In this paradigm, objects to be named were presented in close succession, either from the same semantic categories (homogeneous: elephant, lion, deer, tiger, and cat) or different ones (heterogeneous: pear, shoes, lips, saw, and deer). Naming latencies are longer in the homogeneous context due to the heightened activation of competitors, and the difference in latencies between the homogeneous and heterogeneous contexts is referred to as semantic context effect. The participants were 25 young, healthy Bengali-English bilinguals and 25 healthy, age-, gender- and education-matched English monolinguals. All participants performed a blocked-cyclic naming task in English as well as three independent executive control tasks, tapping into their inhibitory control (Stroop task), mental-set shifting (colour-shape switch task), and working memory (backward digit span task). The key group differences were as follows: bilinguals showed less semantic context effect and more semantic facilitation on the first presentation cycle, applied more selective inhibition in both blocked-cyclic picture naming and Stroop tasks as measured by delta plots, showed better inhibitory control (Stroop task) and shifting abilities, but showed comparable working memory span. The correlation findings for both groups were as follows: slope of the slowest delta segment correlated with the magnitude of the semantic context effect in the blocked-cyclic naming task, no correlation between the slope and interference effect in the Stroop task, no correlation between slope of the two tasks, and no correlations between the semantic context effect with any of the measures derived from the independent executive control tasks. This is the first study to establish that bilinguals are less affected by semantic context manipulation and show a reduced interference effect for the longest naming latencies, compared to monolinguals. It also illustrates that even in a challenging linguistic task that heightens lexical competition, bilinguals performed better than monolinguals. This challenges the notion that bilinguals are disadvantaged compared to monolinguals in linguistic tasks, and we conclude that this study provides evidence for the advantage of bilingualism in linguistic tasks where executive control demands are higher.
