Betriebe lernen Ältere schätzen

Durch die demographische Entwicklung nimmt der Anteil der ?lteren Arbeitskr?fte stetig zu, w?hrend das Erwerbspersonenpotenzial insgesamt langfristig sinkt. Die Unternehmer müssen daher immer mehr ?ltere Arbeitnehmer neu einstellen. Hier k?nnte es aufgrund verschiedener Anforderungen zu Problemen kommen. Die Autorin untersucht die Besch?ftigungschancen ?lterer beispielhaft in sechs hessischen Regionen.     

Mechanism Connecting Environmental Friendliness to Service Loyalty: The Role of Positive Customer Emotions and Satisfaction

This research explores the mechanisms linking consumers’ perceptions of the environmental friendliness of service to customer loyalty. It investigates positive emotions evoked by perceptions of environmental friendliness and then links these emotions to customer satisfaction and loyalty as outcome variables. The data for testing a set of hypotheses was collected from a sample of over 150 consumers for three service industries, each. The results suggest that positive emotions in the form of “warm glow” feelings and sense of belonging are encouraged by environmental friendliness. The positive emotions have direct impacts on satisfaction, but show mixed impacts on loyalty.     

Cartels and norms in the Swedish steel industry 1923–1953

This article discusses the reasons for cartel stability by using the Swedish Steel Casting Cartel as an example. Previous research points out organisational structure and the ability to deal with exit entry and cheating as crucial for stability. In this article, the development of social norms, morally legitimised within the cartel, is discussed as a possible explanation for cartel stability. The organisational structure developed was flexible enough to deal with problems of exit entry and cheating. The discussions on quotas and prices led to a common view on fair prices. The conclusion is that the organisational structure can partly explain why the Steel Casting Group was relatively stable but that there are indications that the development of common social norms related to the value of fairness was also an important explanatory factor.     

A supermartingale relation for multivariate risk measures

The equivalence between multiportfolio time consistency of a dynamic multivariate risk measure and a supermartingale property is proven. Furthermore, the dual variables under which this set-valued supermartingale is a martingale are characterized as the worst-case dual variables in the dual representation of the risk measure. Examples of multivariate risk measures satisfying the supermartingale property are given. Crucial for obtaining the results are dual representations of scalarizations of set-valued dynamic risk measures, which are of independent interest in the fast growing literature on multivariate risks.     

Elicitability and identifiability of set-valued measures of systemic risk

Current account imbalances and financial integration in the euro area

While the current account of the euro area as a whole has remained almost balanced in the past two decades, several member countries have sizeable deficits or surpluses. In this paper, we interpret these imbalances as indicators of net capital flows among the euro-area countries. We distinguish between balances against the euro zone and the rest of the world and examine these for the EU-15 countries. We find that for euro members the net flows follow differences in per-capita incomes, even before the introduction of the euro. Our results show further that with the introduction of the common currency the elasticity with respect to per-capita incomes of net capital flows within the euro area has increased for the members of the euro zone. This increase can neither be observed for the flows between the euro members and the rest of the world nor for the flows between the countries that stayed outside the monetary union and the euro zone. We interpret this as evidence for increasing financial integration in the euro area. There is also some evidence suggesting that the introduction of the euro has led to some financial diversion.
