Endlich besser schlafen

Schlafst?rungen erkennen und behandeln — Erholsamer Schlaf ist die Grundvoraussetzung für k?rperliche und geistige Leistungsf?higkeit. Doch für viele Menschen ist das Ein- und Durchschlafen ein n?chtlich wiederkehrender Kampf. Auch bei den Bewohnern von Pflegeeinrichtungen sind Schlafst?rungen verbreitet. Mitunter k?nnen aber bereits einfache, gezielte Ma?nahmen den Schlaf wieder stabilisieren.     

Examining the relationship between customer and entrepreneurial orientation on nascent firms’ marketing strategy

Is entrepreneurial marketing (EM) a ??one type fits all?? approach? Research suggests that EM is especially suitable for small firms. However, it is obvious that??despite their size??small firms show a myriad of different characteristics. In this paper, it is argued that different firm characteristics can be seen in different business orientations, namely customer orientation (CO) and entrepreneurial orientation (EO). In turn, different amounts of EO and CO lead to different forms of EM strategy. The Panel Study of Entrepreneurial Dynamics (PSED) serves as source to investigate relationships between EO, CO, and respective marketing strategies among nascent firms. The study suggests that innovativeness is strongly related to the importance of several marketing strategies, such as developing new or advanced product or process technologies. However, other strategies, such as lower prices or convenient location, are not related to either significant levels of CO or EO. The paper offers two main implications. Firstly, small business founders have to be aware of the fact that certain strategies cannot come ??out of nowhere??. This paper shows that running proactive marketing strategies that aim for ongoing innovativeness require the existence of an underlying EO. Secondly, there are different forms of ??small firm EM??; a finding that requires further research in the future.     

The long-run determinants of inequality: What can we learn from top income data?

This paper studies determinants of income inequality using a newly assembled panel of 16 countries over the entire twentieth century. We focus on three groups of income earners: the rich (P99–100), the upper middle class (P90–99), and the rest of the population (P0–90). The results show that periods of high economic growth disproportionately increases the top percentile income share at the expense of the rest of the top decile. Financial development is also pro-rich and the outbreak of banking crises is associated with reduced income shares of the rich. Trade openness has no clear distributional impact (if anything openness reduces top shares). Government spending, however, is negative for the upper middle class and positive for the nine lowest deciles but does not seem to affect the rich. Finally, tax progressivity reduces top income shares and when accounting for real dynamic effects the impact can be important over time.     

The cause of Danish unemployment: Demand or supply shocks?

We study the Danish unemployment experience 1905–92 using a common trends model with cointegration constraints. To justify the identifying assumptions about the cointegration vectors and the common trends we present a simple macroeconomic model of the labor market. The model determines the long run behavior of labor productivity, employment, unemployment, real product and real consumer wages. The empirical results give support for three cointegration relations and two common trends. Based on the economic model the trends are interpreted as representing labor productivity (technology) and labor supply. With unemployment being nonstationary, the common trends analysis indicates that labor supply shocks is the primary source for explaining the behavior of unemployment.

Coping with the African Business Environment: Enterprise Strategy in Response to Institutional Uncertainty in Tanzania

Weak institutions, endemic market failures and low trust permeate the Tanzanian business environment. Nevertheless, some local enterprises overcome these challenges. Based on case studies of Tanzanian food processing enterprises, this paper identifies a number of coping strategies that contrasts markedly with the strategies traditionally emphasized by the strategic management literature: Instead of focus strategies, Tanzanian enterprises diversify; Instead of competitive strategies, Tanzanian enterprises adopt network strategies; And instead of internationalizing based on strengths, Tanzanian enterprises internationalize to overcome weaknesses. The paper traces these strategies back to specificities of the Tanzanian institutional environment and discusses implications for the strategic management literature.     

Estimating Precision and Recall for Deterministic and Probabilistic Record Linkage

Linking administrative, survey and census files to enhance dimensions such as time and breadth or depth of detail is now common. Because a unique person identifier is often not available, records belonging to two different units (e.g. people) may be incorrectly linked. Estimating the proportion of links that are correct, called Precision, is difficult because, even after clerical review, there will remain uncertainty about whether a link is in fact correct or incorrect. Measures of Precision are useful when deciding whether or not it is worthwhile linking two files, when comparing alternative linking strategies and as a quality measure for estimates based on the linked file. This paper proposes an estimator of Precision for a linked file that has been created by either deterministic (or rules‐based) or probabilistic (where evidence for a link being a match is weighted against the evidence that it is not a match) linkage, both of which are widely used in practice. This paper shows that the proposed estimators perform well.     

Trust and the don't‐want‐to‐complain bias in peer‐to‐peer platform markets

This paper addresses peer‐to‐peer (P2P) digital platform markets, often associated with the “sharing economy” or the “collaborative economy”. Such digital platforms, facilitating new purchasing channels for consumers by matching P2P supply and demand, can be considered new market places challenging the conventional markets. How are P2P platform markets evaluated by the consumers? Based on a comprehensive survey‐data material, five different P2P service markets are considered by peer buyers and the results compared to consumers’ evaluations from similar conventional service markets according to trust, comparability and consumers’ satisfaction with the transactions. Comparability seems to be one advantage for the platform markets, while trust could become a problem. Conditions for trust in P2P platform markets is particularly interesting to study because contrary to conventional markets P2P transactions cannot rely on governmental laws, regulations and security net. This trust problem has been solved by a trust‐generating rate and review system. Our data material, however, distinguishes a mechanism that we have coined as the don't‐want‐to‐complain bias. More precisely, people do not like to complain, hence buyers of P2P services often hesitate to give negative ratings when they are discontent with a service or a supplier. Therefore, positive ratings become overestimated. If consumers recognize this bias, ratings and reviews will lose credibility and no longer be considered trustworthy. Eventually, this may threaten the well‐functioning of P2P markets.     

Towards an alternative theory of the advertising communication process?

Several findings reported by researchers working in quite different areas suggest that individuals may be able to receive advertising in a way which is very different from the advertising communication process. Here, some of these findings are presented. They derive from studies of picture perception, of mere exposure, of brain lateralization, of emotion formation, of attention processes, and from new approaches to content analysis. Finally, the need for a revised view on how advertising works is emphasized.
