  abstract  = {The study explores differences between three user types in the top tweets about the 2015 "refugee crisis" in Germany and presents the results of a quantitative content analysis. All tweets with the keyword "Fl{\"u}chtlinge" posted for a monthlong period following September 13, 2015, the day Germany decided to implement border controls, were collected (N = 763,752). The top 2,495 tweets according to number of retweets were selected for analysis. Differences between news media, public and private actor tweets in topics, tweet characteristics such as tone and opinion expression, links, and specific sentiments toward refugees were analyzed. We found strong differences between the tweets. Public actor tweets were the main source of positive sentiment toward refugees and the main information source on refugee support. News media tweets mostly reflected traditional journalistic norms of impartiality and objectivity, whereas private actor tweets were more diverse in sentiments toward refugees.},

  abstract  = {Based on large representative German household survey data, we compare incomes of the self-employed with those of paid employees. We find that the entrepreneurial income gap is largest for those holding a tertiary degree, but in two directions: positive for employers (self-employed with further employees) and negative for solo entrepreneurs. Entrepreneurs holding a tertiary degree also face the greatest income variation. However, some solo self-employed earn more than their employed counterparts, in particular those with a university entrance degree as the highest level of education.},

  abstract  = {This article contributes to the debate on the use of performance information in the context of public sector performance management. Based on case studies, the authors analyze the appropriateness of the performance information provided in the newly established performance budgets of municipalities in Germany and Italy. They also examine the interest of politicians and senior managers in using such information for decision-making and monitoring within the municipal budget cycle. They find that the use of performance information is generally quite modest, and that the interest of different local actors varies to a great extent. Politicians are generally less interested in such information than top managers, particularly chief financial officers. The results are discussed by applying a theoretical framework based on institutional and legitimacy theories, and are compared with the literature on performance information use.},

  abstract  = {Germany experienced a unique rise in the level of self-employment in the first two decades following unification. Applying the nonlinear Blinder-Oaxaca decomposition technique, we find that the main factors driving these changes in the overall level of self-employment are demographic developments, the shift towards service sector employment and a larger share of population holding a tertiary degree. While these factors explain most of the development in self-employment with employees and the overall level of self-employment in West Germany, their explanatory power is much lower for the stronger increase in solo self-employment and in self-employment in former socialist East Germany.},
