Zur Integration heuristischer Managementstrategien in die Dynamische Finanzanalyse

Dynamic financial analysis (DFA) has become an important tool in analyzing the financial situation of insurance companies. Constant development and documentation of DFA tools has occurred during the last years. However, several questions concerning the implementation of DFA systems have not been answered in the DFA literature to date. One such important issue is the consideration of management strategies in the DFA context. The aim of this paper is to study the effects of different management strategies on a non-life insurer’s risk and return profile. Therefore, we extend the results of a recent working paper by Eling / Parnitzke / Schmeiser (2007) with two variants and test these variants numerically within a DFA simulation study.     

Momentum Investing and Business Cycle Risk: Evidence from Pole to Pole

We examine whether macroeconomic risk can explain momentum profits internationally. Neither an unconditional model based on the Chen, Roll, and Ross (1986) factors nor a conditional forecasting model based on lagged instruments provides any evidence that macroeconomic risk variables can explain momentum. In addition, momentum profits around the world are economically large and statistically reliable in both good and bad economic states. Further, these momentum profits reverse over 1‐ to 5‐year horizons, an action inconsistent with existing risk‐based explanations of momentum.     

Why Do the Swiss Rent?

At less than 34%, Switzerland has the lowest home ownership rate in Western Europe. This may seem odd given the economic strength of the country. We use household survey data for five Swiss cantons to explore some possible reasons for this. We estimate a tenure choice equation that allows us to analyze the impacts of a number of key variables on the ownership rate. We pay particular attention to the relative cost of owning and renting, which is a function of house prices, rents, and the user cost of owning. The latter is a function of income tax policy and expected house price inflation, among other things. We also measure mortgage underwriting criteria and consider rent control and other policies affecting rental housing. By simulating a number of hypothetical changes to taxation and other policies, underwriting criteria, and price levels, we assess the importance of these variables in explaining the ownership rate. We conclude that high house prices—relative to household incomes and wealth—and the tax on imputed rent are the most important causes of Switzerland’s low ownership rate.     

Accelerators as start-up infrastructure for entrepreneurial clusters

ABSTRACT

Infrastructure is commonly conceptualized as a set of facilities that play a critical role in facilitating activities by individuals and organizations. Conventionally, infrastructure is tightly linked to publicly funded projects that facilitate access to key resources and enable diverse activities. Within entrepreneurial clusters research, infrastructure includes universities, research institutions and telecommunication technologies that facilitate entrepreneurial activities. These capital-intensive investments seek to facilitate start-ups emergence by aiding access to markets and development of ideas. Accelerators facilitate the same activities and have only recently been conceptualized as start-up infrastructure. This study builds upon this research stream by elaborating on how accelerators can play this meaningful role at the cluster level. Specifically, and by relying on the analysis of empirical evidence from three distinct studies, we uncover how accelerators provide tangible and intangible dimensions of start-up infrastructure to form a positively reinforcing cycle of entrepreneurial activities. Additionally, our findings allow us to push further the idea that start-up infrastructure development can be an endogenous process involving multiple actors within the cluster. Our empirical findings and the theoretical insights derived from them have meaningful implications for the aforementioned literature, as well as start-up practitioners and policymakers linked to the funding of entrepreneurial clusters.     

THE USE OF CONTRACT BY GOVERNMENT AND ITS AGENTS

Given that the provision of a service is being controlled by the state, the decision whether to contract out that service provision to the private sector is essentially a business decision. A number of economic advantages and disadvantages need to be offset against each other. Governments are poorly placed to make such decisions and it is no surprise that PPPs are often inefficient and steered by political objectives.
