What is progress in transdisciplinary research?

In disciplinary research progress is reached and assessed by referring to the state of research in a specific field. But what is progress in transdisciplinary research, where several disciplines and further societal actors may be involved? Based on the conception of transdisciplinary research as a collaboration of academic as well as non-academic thought-styles, and based on the understanding of transdisciplinary research as research that develops a comprehensive, multi-perspective, common-good oriented and useful approach to a socially relevant issue, the question of progress is discussed for four view-points: (a) the people concerned about the issue are much less interested in the question of progress in transdisciplinary research than in a better handling of the real world problem; (b) members of a disciplinary, business, governmental or civil society's thought-style, who gain a more comprehensive understanding of an issue through the transdisciplinary research process, are more interested in further elaborating the issue within their thought-style, than in general lessons on progress; (c) progress on the level of personal experience mainly means that members of academic or non-academic thought-styles realize that they are a member of a specific thought-style among others. Progress would be made by integrating this experience in general education and special training; (d) finally a lot of general lessons can be learned and elaborated as tools, cases studies and approaches form the perspective of a thought-style interested in how to understand and manage transdisciplinary research.     

Aktuelle Rechtsfragen der Umweltschadensversicherung

The paper provides an overview of current legal issues with regard to the environmental damage insurance, which exists in Germany since 2007. At the center of the observation are limitations of coverage, in particular the requirement of a malfunction of the business operations, the exclusion of qualitative risk changes and the cost deduction clause. In addition, the article deals with some issues of interpretation as well as of delimitation with regard to further insurance policies. By way of introduction the basics of the German Environmental Damage Act (USchadG) and its underlying EU Directive are shown. Finally, the authors discuss the question whether the environmental damage insurance should be configured as an obligatory insurance in the future.     

Market segmentation,performance differences and strategic orientation - the case of German reinsurers

We apply the concept of strategic groups to the German reinsurance market. We use a cluster analysis to subdivide reinsurance companies into strategic groups and analyze the effect of a set of strategic choice variables on their performance. Furthermore, we examine the impact of the financial crisis of 2008 on the reinsurance sector. Our dataset encompasses 142 firm-year observations for the years 2004 until 2012. Our results indicate the existence of three strategic groups in the German reinsurance market. Moreover, we find that most strategic choice variables that characterize the individual strategic groups affect the reinsurers’ level of performance. Finally, we find that the reinsurers’ performance increased in the aftermath of the financial crisis. This holds in particular for professional reinsurance companies.     

Analysis of Systemic Risk in the Insurance Industry

In this paper, we discuss the systemic relevance of the insurance sector. Systemic risk is defined as the propensity of a financial institution to be undercapitalised when the financial system as a whole is undercapitalised. By the law of large numbers, traditional lines of insurance with idiosyncratic non-catastrophic risks cannot be systemic. On the contrary, undiversified insurers specialised in activities whose insured risks are highly correlated with GDP are systemic. In the life insurance sector, some contractual clauses such as unhedged minimum guarantees and free options to surrender raise the chance of systemic relevance. On the contrary, life insurers satisfying the classic solvency capital requirements contribute to the liquidity of financial markets thanks to the long-termist approach of their portfolio management. Finally, using historical data in the U.S. on the contribution of different sectors to the aggregate volatility of the economy, we show that investment banking is almost twice as volatile as aggregate GDP, while insurance is one fifth as volatile as aggregate GDP. The insurance sector thus appears to be a stabilising force of the economy.     

Merger policy and tax competition: the role of foreign firm ownership

In many situations, governments have sector-specific tax and regulation policies at their disposal to influence the market outcome after a national or an international merger has taken place. In this paper we study the implications for merger policy when countries non-cooperatively deploy production-based taxes and firms may be partly owned by foreigners. We find that when foreign firm ownership is low in the pre-merger situation, non-cooperative tax policies are more efficient after a national merger, and smaller synergy effects are needed for this type of merger to be proposed and cleared. In contrast, cross-border mergers dominate when the degree of foreign firm ownership is high initially. These results suggest a link between increasing international portfolio diversification and the rising share of cross-border mergers.     

The Role of Bank and Corporate Balance Sheets on Early Warning Systems of Currency Crises—An Empirical Study

This study analyzes the role of bank and corporate balance sheets on early warning systems (EWS) of currency crises. Using firm-level data on debt structure, leverage, liquidity, and profitability, this study presents estimations of EWS for a panel of emerging markets. Using calibration experiments, we assess the performance of alternative EWS specifications in a comprehensive range of crisis-probability cut-offs?. These models supplement EWS based on traditional macroeconomic indicators, improving forecasting performance substantially. The results support the third-generation models of currency crises and can assist policymakers on the design of surveillance strategies tailored for heterogeneous levels of risk tolerance and country specificities.     

A simple correction of the WACC discount rate for default risk and bankruptcy costs

Standard discounted cash flow approaches suffer from a rudimental modeling of the possibility of a default, as the main characteristics such as the default probability and potential bankruptcy costs are commonly disregarded. This paper aims at providing a tractable extension of the well-known WACC approach for both default risk and bankruptcy costs. The corrected WACC discount rate reveals that default risk results in a systematically higher WACC because the tax component is scaled by the survivorship probability and an aditional component for bankruptcy costs must be added. This difference between the classical WACC discount rate and the simple modified WACC rate can be remarkable especially for firms from businesses with high bankruptcy costs and a relevant default probability.
