Ich fühle,also bin ich — Markenemotionen machen den Unterschied

Marken l?sen Gefühle bei den Konsumenten aus. Eine Studie zeigt: Starke Marken profitieren von den mit ihnen verknüpften positiven Emotionen, schwache Marken hingegen k?nnen sogar negative Gefühle erzeugen. Es gilt also, Marken „positiv aufzuladen“. Denn st?rkere Markenbindung und gesteigerte Markenbegehrlichkeit wirken sich letztendlich auch positiv auf die Kaufentscheidung der Verbraucher aus.

Evolutionary stable stock markets

Summary. This paper shows that a stock market is evolutionary stable if and only if stocks are evaluated by expected relative dividends. Any other market can be invaded in the sense that there is a portfolio rule that, when introduced on the market with arbitrarily small initial wealth, increases its market share at the incumbents expense. This mutant portfolio rule changes the asset valuation in the course of time. The stochastic wealth dynamics in our evolutionary stock market model is formulated as a random dynamical system. Applying this theory, necessary and sufficient conditions are derived for the evolutionary stability of portfolio rules when relative dividend payoffs follow a stationary Markov process. These local stability conditions lead to a unique evolutionary stable portfolio rule according to which assets are evaluated by expected relative dividends (with respect to the objective probabilities).Received: 7 October 2003, Revised: 18 January 2005, JEL Classification Numbers: G11, D52, D81.

A dynamic model of settlement

We investigate the role of settlement in a dynamic model of a payment system where the ability of participants to perform certain welfare-improving transactions is subject to random and unobservable shocks. In the absence of settlement, the full information first-best allocation cannot be supported due to incentive constraints. In contrast, this allocation can be supported if settlement is introduced, provided that it takes place with a sufficiently high frequency.     

Das Mindestlohngesetz — Hoffnungen und Befürchtungen

The German government plans to introduce a minimum wage from 2015. This must be understood as a response to the decline in collective bargaining coverage and the marked increase in employment in the low-wage sector. The authors discuss how many workers are affected by this new regulation and whether the minimum wage is too high in relation to the average wage of workers (Kaitz index). They assume that the introduction of a minimum wage in Germany can have a number of effects. It is not possible to forecast all the reactions and behaviour of market participants to handle higher wages and goods prices. Some authors warn that these measures are significant labour market interventions that could have adverse employment effects. They recommend allowing more exemptions from the minimum wage law than intended by the government, especially for young employees and student apprentices. Other authors hope that minimum wages would help to strengthen collective bargaining and stabilise wages. Some authors emphasise that there should be a careful evaluation of the economic effects by scientists.
