Analyse der Marktaussichten von Biogasanlagen

Without guaranteed compensation, granted by the German Renewable Energy Sources Act (Erneuerbare Energien Gesetz/EEG), biogas plants compete with all other plant types on the market for electrical energy. However, exchange-based electricity products do not currently permit an economically viable operation of biogas plants owing to their cost situation.     

Strategic Patenting in Biotechnology

Patents can be used by their owners in a variety of strategic ways in the market place that do not necessarily conform with the original idea of patents as a remedy against market failure. More patenting does not lead to more innovation in all cases. This article looks at the relevance of patents and their strategic uses in the biotechnology industry. The article considers the different motives for applying for patents and various strategies. Theoretical considerations are made based on empirical findings from a survey of the Swiss biotechnology industry carried out in 2003. The empirical data confirm that patents for biotechnological inventions are important as an incentive for investment in R&D and that patents are an efficient tool for protecting biotechnological inventions. Strategic patenting is not very common in Switzerland and there are no signs for an abusive level of strategic patenting.     

What you are is what you like—similarity biases in venture capitalists' evaluations of start-up teams

This paper extends recent research studying biases in venture capitalist's decision making. We contribute to this literature by analyzing biases arising from similarities between a venture capitalist and members of a venture team. We summarize the psychological foundations of such similarity effects and derive a set of hypotheses regarding the impact of similarity on the assessment of team quality. Using data from a conjoint experiment with 51 respondents, we find that venture capitalists tend to favor teams that are similar to themselves in type of training and professional experience. Our results have important implications for academics and practitioners alike.     

Modelling and forecasting liquidity supply using semiparametric factor dynamics

We model the dynamics of ask and bid curves in a limit order book market using a dynamic semiparametric factor model. The shape of the curves is captured by a factor structure which is estimated nonparametrically. Corresponding factor loadings are modelled jointly with best bid and best ask quotes using a vector error correction specification. Applying the framework to four stocks traded at the Australian Stock Exchange (ASX) in 2002, we show that the suggested model captures the spatial and temporal dependencies of the limit order book. We find spill-over effects between both sides of the market and provide evidence for short-term quote predictability. Relating the shape of the curves to variables reflecting the current state of the market, we show that the recent liquidity demand has the strongest impact. In an extensive forecasting analysis we show that the model is successful in forecasting the liquidity supply over various time horizons during a trading day. Moreover, it is shown that the model's forecasting power can be used to improve optimal order execution strategies.

Hostages, free lunches and institutional gaps: the case of the European Currency Union

This paper argues that the strong member states of the European Currency Union are hostages of a financially distressed member state so that they are compelled to provide financial support. Moreover, due to the dynamics of the interaction game, a debt relief is a free lunch for the distressed country. This fosters moral hazard of distressed countries. In the absence of capital market control, European politics do not effectively monitor fiscal politics of member states. The lack of a long-term strategy of the European Currency Union to deal with distressed states has undermined the credibility of politics. This lack is also explained by a lack of a European Insolvency Charter. A viable Union requires such a charter with rules for handling distress. Moreover, politics should determine a mechanism to coordinate politics and capital markets in their monitoring of fiscal and economic policy of member states.
