Katastrophenanleihen als Risikotransfer-Instrument für Industrieunternehmen

All over the world an increase in natural catastrophes and resulting damages can be observed for entire economies as well as for individual industrial enterprises. This trend leads to extraordinary expensive traditional natural catastrophe insurance or even a lack of insurance capacities. Due to the increased threat resulting from natural catastrophes and the inefficiencies of traditional insurance solutions, it will be analyzed in the following whether catastrophe bonds (cat bonds), as an alternative risk transfer instrument, should play a role in the risk management portfolio of industrial companies. It will be discussed whether catastrophe bonds are possible risk transfer instruments for industrial companies and whether certain basic prerequisites for a confirmation of the suitability are recognizable. In a further step, the design possibilities for cat bonds will be presented and the most suitable design alternatives for industrial companies as issuers of cat bonds will be elaborated. In addition, a critical comparison between the usage of traditional insurance solutions and cat bonds by industrial companies in order to protect themselves against natural catastrophes will be conducted. The result is a first orientation and a general guideline for dealing with catastrophe bonds as part of the operational risk management for industrial companies.     

Revisiting the sectoral Linder hypothesis: Aggregation bias or fixed costs?

This paper reassesses and revisits the Sectoral Linder Hypothesis due to Hallak, which posits that similar tastes for quality lead to more intensive trade between similar countries at the sectoral level. First, the measure of demand similarity used in this paper is based on the distribution of income estimated from household surveys. The paper finds that a similarity measure based on the income distribution produces stronger results than the traditionally used measure based on GDP per capita. Moreover, the country/product level extensive margin is taken into account. This is important because similarity is likely to affect the fixed costs of trade and the fixed costs of alternative means of servicing a market (i.e., licensing and FDI). Fixed costs, in turn, affect the number and average productivity of firms that engage in bilateral trade and hence the overall volume of trade. This paper employs the method by Helpman et al. to control for the extensive margin. Heteroskedasticity is addressed using a feasible generalized least squares (FGLS) approach. The findings show that once controlling for the effect of similarity on the extensive margin, the Linder hypothesis holds at more aggregate levels. Other robustness checks suggest that results are not confined to products that are vertically differentiated.     

Does GDP Distort Mexico's Economic Performance?

Between 1961 and 1980, Mexico's gross domestic product (GDP) per capita grew nearly 3.50% annually. During the 1980s, however, it shrank about 0.50% per year. GDP figures suggest that there was sustained economic growth for the 1960s and 1970s, changing suddenly to contraction in the 1980s. This impression may be misleading. GDP does not account for housework or informal production outside households. Further, GDP also may be distorted by transactional activities, which are expenditures to support transactions, not actual output consumed. This study recalculates output for Mexico for the 1961-1990 sample period, controlling for transactional activities and nonmarket production. We find that GDP misstates Mexico's “actual” economic growth. In the 1960s, the economy expanded more quickly than GDP suggests. But in the 1970s, growth was less than half that of the 1960s. The economy indeed slumped in the 1980s, but not as terribly as the official figures indicate. Mexico's economy did not collapse suddenly in the early 1980s; actual economic growth had slowed dramatically during the 1970s.     

Regression analysis on serial dilution data from virus validation robustness studies

To ensure the safety of plasma-derived medicinal products, the Dutch Blood Supply Foundation (Sanquin) performs virus validation experiments. Data from these experiments are based on serial dilution assays. Regression analysis on assay data faces several problems: only a small number of data points are available, data contain censoring and are subject to sampling error. Furthermore, the process variability inherent to the experiments is not evident. In this paper we address these problems by introducing a regression model for serial dilution data and by analyzing how validation experiments and simulation techniques can help elucidate various sources of variability the experiments are subject to. These are then incorporated into the regression model.     

Stromspeicher für die „Energiewende“ – eine akteursbasierte Analyse der zusätzlichen Speicherkosten

Political targets for implementing the German “energy turnaround” aiming at the ambitious extension of renewable energies to generate electricity. However, a majority of the renewable supply is provided by intermittent sources, e.g. wind and solar power. For balancing the increasing supply fluctuations additional storage options are claimed beside of an enforced grid infrastructure and a more flexible demand side. Despite of the political guidelines the economics of additional flexibility measures has to be considered. For this paper we analyse the costs of large scale stationary battery storages to be operated in wholesale markets and transmission grid level. By deriving a key figure based on a life-cycle cost approach, we are able to evaluate the additional costs of electricity of selected battery technologies (lead-acid, lithium ion, sodium sulphur, redox-flow). Moreover, current and valid parameters of the cost analysis are received by scientific and industrial stakeholders of battery systems via online survey and face-to-face interviews. According to the stakeholder estimation a nationwide operation of stationary battery storages will be established at wholesale and transmission grid level until the year 2030. The life-cycle cost analysis, which also includes estimated future cost reductions, shows that lead-acid batteries remain the cost-efficient technology, assuming about 100 storage cycles p.a. In addition, a sensitivity analysis reveals the impact of increasing annual storage cycles as well as the achievable cost reduction by economies-of-scales of the power unit of the storage system.     

Dilemmas of Downsizing During the Great Recession: Crisis Strategies of European Employers

The present paper analyzes the choices faced by European employers when threatened with the prospect of the mass lay-off of their employees as a result of the Great Recession. By means of a representative survey among employers in Italy, Germany, Denmark, Poland, the Netherlands and Sweden in 2009, we show that employers mainly prefer to tackle such threats by offering short-time work, and by early retirement packages to older workers, in conjunction with buy-outs. The latter preference is particularly visible in countries where employers perceive the level of employment protection to be high. The only notable exception is Denmark, where employers prefer to reduce working hours. In general, a sense of generational fairness influences downsizing preferences, with those employers who favor younger workers particularly likely to use early retirement and buy-outs when downsizing, followed by working time reductions. Wage reductions and administrative dismissal are less favored by European employers. In particular, CEOs and owners are more inclined than lower-level managers to cut wages.     

HEALTHY MINDS IN HEALTHY BODIES: AN INTERNATIONAL COMPARISON OF EDUCATION-RELATED INEQUALITY IN PHYSICAL HEALTH AMONG OLDER ADULTS

We study education-related inequality in the physical health of older adults across 11 European countries and the United States. Combining the data from Health and Retirement Study 2002, the English Longitudinal Study of Ageing 2002 and the Survey of Health, Ageing and Retirement in Europe 2004, our results suggest that education is strongly correlated with health both across and within countries. Education-related inequality in health is larger in Mediterranean and Anglo-Saxon countries than in western European countries. We find no evidence of a trade-off between health levels and equity in health. Education-related inequality in health is hardly driven by income or wealth effects (except in the United States), and differences in health behaviours (smoking) by education level contribute little to health differences across education groups.     

Linking multi-channel customer behavior with shopping motives: An empirical investigation of a German retailer

Operating multiple channels, in store as well as non-store, allows a retailer to cater to the different shopping motives of its customers. This research into the buying behavior of 525 customers of a multi-channel retailer that operates five channels in Germany shows that most customers use only one channel within a buying process, selecting the channel that best satisfies their shopping motives in each situation. Based on exploratory qualitative and quantitative research, this study identifies five shopping motives: “recreational orientation”, “convenience orientation”, “independence orientation”, “delivery-related risk aversion” and “product- and payment-related risk aversion”. In the majority of the store channels examined in this study (chain stores and bakeries), single-channel users primarily look to satisfy emotional and social needs. Single-channel users of non-store channels (catalogue and online-shop) look for convenience and strive for independence. Multi-channel users, who obtain their information from the online-shop and then make their purchase in the chain store, are combining the independence of online-shop information with the reduction of risks associated with buying products in the chain store. These findings can be used to develop recommendations for managing the individual channels.     

On discouraging environments in team contests: Evidence from top-level beach volleyball

This contribution empirically investigates the adverse effects of unbalanced competition and negative feedback in team contests in the field. Using a unique data set sourced from top-level beach volleyball, I provide evidence for discouragement effects in line with contest theory. The analysis identifies a non-linear relationship between ex ante contestant heterogeneity and performance. Overall, no gender differences can be found. Finally, it shows that age diversity in teams helps to overcome setbacks.
