Soziale Lage — Was sind die drängendsten Probleme?

Democracy seems to be at risk. People elect populists and autocrats, who offer simple solutions to social problems. Often, these problems are not even real ones but are only perceived as such. Economists have measures to determine which problems are fact-based, but they cannot draw a clear distinction between academic analysis and normative demand. If politics pursues a correction of a market outcome, any normative criteria other than efficiency have to be outlined explicitly. Nevertheless, some authors consider inequality one of the central contemporary social and economic challenges. Marcel Fratzscher emphasises that the solution is not found in more redistribution via taxes and transfers, but rather through greater equality of opportunity and social and educational mobility. Bert Rürup thinks that to stabilise the acceptance of the compulsory pension scheme, the dominance of the equivalence principle should be reduced. Further, the existence of different federal subsidy schemes should be replaced by a fixed federal contribution rate in alignment with the pension expenditures. In an international comparison, the fiscal burden for households with small and mid-level earned incomes is exceptionally high in Germany. In order to reduce this burden, Rürup suggests a contribution-free allowance for the social insurance contributions.     

The Impact of Search and Recommendation Systems on Sales in Electronic Commerce

The Internet and related technologies have vastly expanded the variety of products that can be profitably promoted and sold by online retailers. Furthermore, search and recommendation tools reduce consumers’ search costs in the Internet and enable them to extend their search from a few easily found best-selling products (blockbusters) to a large number of less frequently selling items (niches). As a result, Long Tail sales distribution patterns emerge that illustrate an increasing demand in niches. We show in this article how different classes of search and recommendation tools affect the distribution of sales across products, total sales, and consumer surplus. We hereby use an agent-based simulation which is calibrated based on real purchase data of a video-on-demand retailer. We find that a decrease in search costs through improved search technology can either shift demand from blockbusters to niches (search filters and recommendation systems) or from niches to blockbusters (charts and top lists). We break down demand changes into substitution and additional consumption and show that search and recommendation technologies can lead to substantial profit increases for retailers. We also illustrate that decreasing search costs through search and recommendation technologies always lead to an increase in consumer surplus, suggesting that retailers can use these technologies as competitive advantage.     

Komplexe Kompressionstherapie

pAVK: Wann ist Kompression erlaubt? - Eine periphere arterielle Verschlusskrankheit (pAVK) gilt meist als Kontraindikation für eine komplexe Kompressionstherapie – nicht immer zum Nutzen des Patienten. Bei strenger Indikationsstellung und intensiver Betreuung k?nnen jedoch auch diese Patienten von der Behandlungsform profitieren.     

Der MDK kommt!

Vorbereitung auf die Qualit?tsprüfung — Steht der MDK unangemeldet vor der Tür, kommt es unter den Mitarbeitern h?ufig zu Unsicherheiten, die sich negativ auf die Prüfung auswirken k?nnen. Doch durch klare Aufgabenverteilungen und einen „Handlungsleitfaden“ legen Sie und Ihre Mitarbeiter den Grundstein für ein gutes Prüfungsergebnis.     

Nadelstichverletzungen: Kleiner Pieks mit großer Wirkung

Arbeitsschutz als Führungsaufgabe - Eine kurze Unachtsamkeit oder unglückliche Verkettung von Ereignissen und schon ist es passiert: Die Kanüle trifft das Pflegepersonal. Aber: Nadelstichverletzungen lassen sich durch die Verwendung sicherer Produkte und Injektionstechniken reduzieren. Dabei ist die Verbesserung des Arbeits- und Gesundheitsschutzes des medizinischen und pflegerischen Personals eine wichtige Aufgabe der Führungskr?fte.     

Country-level Accounting Enforcement and IPO Underpricing

Using a sample of up to 2,503 initial public offerings (IPOs) in 32 countries from 2011–2017, we predict and find that higher levels of country-level accounting enforcement are associated with lower levels of IPO underpricing. IPOs in countries with a relatively low accounting enforcement score (second quintile) exhibit a mean underpricing of 19%, whereas the mean underpricing amounts to just 9% in countries with a relatively high score (fourth quintile). The results remain qualitatively the same when we employ a multi-level model or a difference-in-difference design. In countries that substantially strengthened their accounting enforcement in the 2003–2009 period, the level of IPO underpricing decreased significantly. We show that accounting enforcement matters for the cost of going public.     

Control and co-ordination of Japanese subsidiaries in China: problems of an expatriate-based management system

This paper analyses the international management control (IMC) system that Japanese multinational companies (MNCs) employ to co-ordinate the activities of their subsidiaries in China. It focuses on the role of Japanese expatriates in this IMC system and assesses their performance. In the process, it offers a comprehensive evaluation of the organizational fit of the Japanese IMC model within the current Chinese business environment. Taking Japanese firms as the subject, the analysis identifies areas of incongruity and explains the underlying reasons for problems with expatriate-focused IMC models. In doing so, this paper argues that the Japanese expatriate-based control system in China (as in many other parts of the world) continues to be characterized by an insider-outsider mentality that prevents a real internationalization of overseas operations in the 'transnational' sense.
