Neue Produkte schneller am Markt: Vorsprung durch Innovationslabors

Innovative Produkte systematisch und schnell zugleich zu entwickeln, ist für viele Unternehmen heute eine überlebensnotwendige Aufgabe. Konsumenten sollten daher früh in der Entwicklungsphase und nicht erst in der Testphase eingebunden werden. Innovationsmanagement muss zudem m?glichst alle berührten Abteilungen im Unternehmen einbeziehen. Dies erfordert besondere Instrumente. Innovationslabore sind ein Konzept, das die komplexen Anforderungen an das Innovationsmanagement extrem gut bedienen kann.     

The persistence of the small firm/January effect: Is it consistent with investors’ learning and arbitrage efforts?

Using improved methodology and an expanded research design, we examine whether the small firm/January effect (Keim, D. B. (1983). Size-related anomalies and stock return seasonality: further empirical evidence. Journal of Financial Economics 12:13–32), is declining over time due to market efficiency. First, we find that January returns are smaller after 1963–1979, but have simply reverted to levels that existed before that time. Second, we show that the January effect is not limited to mature markets but also appears in firms trading on the relatively new NASDAQ exchange in the 1970s. Third, trading volume for small firms in December and January is not different from other months, implying that traders are not actively arbitraging the anomaly. Together, our results suggest that this anomaly continues to defy rational explanation in an efficient market.     

Structural adjustment and soil degradation in Tanzania A CGE model approach with endogenous soil productivity

In this paper, a model of the nitrogen cycle in the soil is incorporated in a Computable General Equilibrium (CGE) model of the Tanzanian economy, thus establishing a two‐way link between the environment and the economy. For a given level of natural soil productivity, profit‐maximising farmers choose input levels – and hence production volumes – which in turn influence soil productivity in the following years through the recycling of nitrogen from the residues of roots and stover and the degree of erosion. The model is used to simulate the effects of typical structural adjustment policies like a reduction in agro‐chemicals’ subsidies, reduced implicit export tax rate etc. After 10 years, the result of a joint implementation is a 9% higher Gross Domestic Product (GDP) level compared to the baseline scenario. The effect of soil degradation is found to represent a reduction in the GDP level of more than 5% for the same time period.     

Gifted kids or pushy parents? Foreign direct investment and plant productivity in Indonesia

This paper analyzes the causal relationship between foreign ownership and various aspects of plant performance using micro data from the Indonesian Census of Manufacturing. It examines the implications of foreign ownership in two different contexts: foreign acquisitions and foreign privatizations. To control for the possible endogeneity of FDI decision propensity score matching is combined with a difference-in-differences approach. The results indicate that foreign ownership leads to significant productivity improvements in the acquired plants. The improvements become visible in the acquisition year and continue in subsequent periods. After three years, the acquired plants exhibit a 13.5% higher productivity than the control group. The rise in productivity is a result of restructuring, as acquired plants increase investment outlays, employment and wages. Foreign ownership also appears to enhance the integration of plants into the global economy through increased exports and imports. Finally, productivity improvements and evidence of restructuring are also found in the context of foreign privatizations.     

Consumer neuroscience the effect of retail brands on the perception of product packaging

Whereas classical marketing research is restricted to purely analyzing reported and/or behavioral data, the new research area of consumer neuroscience might be able to capture unconscious and emotional processes as well. The present study investigates the neural correlates associated with different retail brand frames. The authors assume that the integration of emotions and memories associated with the image and reputation of a retail brand can influence consumers’ perception of a product packaging.     

Die Emergency Liquidity Assistance der EZB — ein Blick in die Black Box

We do not know much about the ELA of the ECB, even though the degree of financial assistance to the national banking sector is of tremendous importance for the public. This article brings together the scarce information on ELA and its use in several countries so far. Based on this evaluation, improvements in the communication of ELA are derived. The article argues that the currently available option to publish the ELA ceilings should be made mandatory and that increases in the ELA ceiling should be strongly limited.     

Selling digital music: business models for public goods

This paper considers the market for digital music. We claim that the combination of the MP3 format and peer-to-peer networks has made music non-excludable and this feature is essential for the understanding of the economics of the music market. We study optimal business models for selling non-excludable goods and show that despite promising theoretical results, adding just a slight uncertainty about the number of customers has significant negative implications for profitability. Indeed, as the average number of customers tends to infinity the average payment per customer converges to zero. Therefore, the music industry should concentrate on alternative ways of creating profit such as selling access to listeners, concerts, merchandise, ringtones etc.
