Developing an immigration policy for Germany on the basis of a nonparametric labor market classification

Summary: Based on a nonparametrically estimated model of labor market classifications, this paper makes suggestions for immigration policy using data from West Germany of the 1990s. It is demonstrated that nonparametric regression is feasible in higher dimensions with only a few thousand observations. In sum, labor markets are able to absorb immigrants are characterized by above average age and by professional occupations. On the other hand, labor markets for young workers in service occupations exhibit rising unemployment due to wage rigidities and are therefore not recommended for immigration. This raises a potential conflict between financing Germanys ailing social security system and protecting decreasing or rigid labor markets by immigration control.*We are grateful to Daron Acemoglu, Joshua Angrist, Herbert S.

Coaching — Performanceorientierung und Managererwartung

Coaching — orientation on performance and expectations of managersThe author discusses the up to now controversial question what managers are thinking about coaching. The inquiry, developed in the Free University of Amsterdam, asks also for the expectations on coaching. The author finds out, that issues of leading take priority and that not only crises and conflicts are reasons to ask for a coaching, but also desires to improve the personal performance.     

Strategy Formation Across Organizational Boundaries: An Interorganizational Process Model

Strategic decision‐makers today face complex environments with meta‐problems that cut across multiple industries. Single organizations cannot address these meta‐problems. As a result, organizations collaborate with partners, among them also competitors, and commonly work together in multi‐partner initiatives (MPIs). How these organizations jointly form an interorganizational strategy (IOS), however, is not well understood. In this paper, we extend the current strategy process conceptualizations from an intraorganizational focus of a single firm to an interorganizational process of multiple strategy‐making entities working together. We selected the eMobility sector as our research context to develop such an IOS process model. We first developed 25 cases on MPIs in the German‐speaking area based on interviews and desk research, before we focused on the eMobility ecology in the southern part of Germany. We identified 291 MPIs, conducted interviews with 19 central actors, held several workshops and informal gatherings, and complemented these data with an analysis of publicly accessible documents. Using an inductive research design, we developed a process model that unfolds in three phases: initiation, negotiation and execution. We reveal specific process dynamics in MPIs to be critical in the formation and manifestation of IOS.     

The governance of free/open source software projects: monolithic, multidimensional, or configurational?

This paper presents the results of a qualitative review and synthesis of the literature on open source governance, addressing four key questions: (1) How has open source software (OSS) governance been defined? (2) Has the phenomenon of OSS governance been conceptualized as a monolithic or multidimensional phenomenon? (3) What purposes is OSS governance hypothesized to serve? and (4) What are the dimensions of OSS governance, and how are these dimensions related to each other? The results of the review suggest a framework for future comparative and case study research on OSS governance, and they provide a basis for comparison with research on the governance of other distributed, community-based forms of content and creation.     

Issues in the assessment of non-inferiority: perspectives drawn from case studies

Superiority claims for improved efficacy are the backbone of clinical development of new therapies. However, not every new therapy in development allows for such a claim. Some therapies per se do not try to improve efficacy further but concentrate on important aspects in safety or convenience. Such improvements can be equally important to patients, and development strategies should be available for such compounds. A three-arm design with placebo, active control and experimental treatment may be viewed as the golden standard for such compounds; however, it may be difficult if not impossible to add a placebo arm in certain diseases. In such situations, non-inferiority designs are the only development option left. This paper will highlight some of the key issues with such designs in practice and will report experience from two studies from different therapeutic areas intended for regulatory submission.     

Bubbles and Crashes

We present a model in which an asset bubble can persist despite the presence of rational arbitrageurs. The resilience of the bubble stems from the inability of arbitrageurs to temporarily coordinate their selling strategies. This synchronization problem together with the individual incentive to time the market results in the persistence of bubbles over a substantial period. Since the derived trading equilibrium is unique, our model rationalizes the existence of bubbles in a strong sense. The model also provides a natural setting in which news events, by enabling synchronization, can have a disproportionate impact relative to their intrinsic informational content.     

COMPETING AUCTIONS

This paper shows that larger auctions are more efficient than smaller ones, but that despite this scale effect, two competing and otherwise identical markets or auction sites of different sizes can coexist in equilibrium. We find that the range of equilibrium market sizes depends on the aggregate buyer‐seller ratio, and also whether the markets are especially thin. (JEL: D44, L11)     

Taking social policy personally: How does neuroticism affect welfare state attitudes?

The role of the “Big Five” personality traits in driving welfare state attitudes has received scant attention in social policy research. Yet neuroticism in particular—a disposition to stress, worry, and get nervous easily—is theoretically likely to be an important driver of welfare attitudes precisely because welfare states deliver social “security” and “safety” nets. Using cross-sectional data from the German Socio-Economic Panel, we study three distinct attitude types (dissatisfaction with the social security system, feelings of personal financial insecurity, and preferences for state provision) and multiple social need contexts (including unemployment, ill health, old age, and nursing care). Controlling for established explanations such as self-interest, partisanship, and socialization, neuroticism does not systematically affect support for state provision. But it robustly increases general dissatisfaction with social security, as well as financial insecurity across various need contexts. Neurotic people are thus less happy with welfare state programmes across the board, yet they also appear to need these programmes more. This trait may be an important deeper layer driving other social attitudes.     

Globale organisation — globale manager — globale Klasse?

The globalization of business corporations led to the thesis that a so-called global management class would emerge, both integrating transnational companies and facilitating a global business culture which is able to turn cultural diversity into a competitive advantage. Two questions stem from this thesis: First, how do talents and high potentials in transnational companies become global managers? Second, is global management to be understood as an integrating culture or as a selective one in the context of transnational corporations? The article explores these questions by contrasting the theory of global management with empirical findings from research concerning the strategies of international management assignment and the forming of expatriates’ “mental memberships“. It is shown that global management rests on a ‘thin’ Ethos of economic rationalities which give way to an exclusive “business monoculture” challenging cultural diversity taking place in everyday-life of transnational organizations.
