Risk Sharing and Efficiency Implications of Progressive Pension Arrangements*

This paper aims to quantify the welfare effects of progressive pension arrangements in Germany. Starting from a purely contribution‐related benefit system, we introduce basic allowances for contributions and a flat benefit fraction. Since our overlapping‐generations model takes into account variable labor supply, borrowing constraints as well as stochastic income risk, we can compare the labor supply, the liquidity and the insurance effects of the policy reform. Our simulations indicate that it would be optimal to introduce a flat benefit share of 50 percent and a basic allowance that amounts to 30 percent of average income. Such a reform would yield an aggregate efficiency gain of 3.3 percent of resources.

Strategic factor markets,scale free resources,and economic performance: The impact of product market rivalry

This paper analyzes how scale free resources, which can be acquired by multiple firms simultaneously and deployed against one another in product market competition, will be priced in strategic factor markets, and what the consequences are for the acquiring firms' performance. Based on a game‐theoretic model, it shows how the impact of strategic factor markets on economic profits is influenced by product market rivalry, preexisting competitive (dis)advantages, and the interaction of acquired resources with those preexisting asymmetries. New insights include the result that resource suppliers will aim at (and largely succeed in) setting resource prices so that the acquiring firms earn negative strategic factor market profits—sacrificing some of their preexisting market power rents—by acquiring resources that they know to be overpriced.

Modelling the Link Between US Inflation and Output: The Importance of the Uncertainty Channel

This article employs an augmented version of the UECCC GARCH specification proposed in Conrad and Karanasos (2010) which allows for lagged in‐mean effects, level effects as well as asymmetries in the conditional variances. In this unified framework, we examine the twelve potential intertemporal relationships among inflation, growth and their respective uncertainties using US data. We find that high inflation is detrimental to output growth both directly and indirectly via the nominal uncertainty. Output growth boosts inflation but mainly indirectly through a reduction in real uncertainty. Our findings highlight how macroeconomic performance affects nominal and real uncertainty in many ways and that the bidirectional relation between inflation and growth works to a large extent indirectly via the uncertainty channel.     

Fare Thee Well? An Analysis of Buyout Funds’ Exit Strategies

This paper analyzes exit strategies of buyout funds in portfolio companies following initial public offerings (IPOs). We use a data set of 222 buyout‐backed IPOs in the United States from 1999 to 2008, including hand‐collected data about each exit process, to draw a detailed roadmap of buyout investors’ divestment processes. Using this data, we document the timing and aggressiveness of the exit strategies, and analyze to which degree a multitude of possible determinants influence the choice of a given exit strategy. Our results indicate that buyout funds remain invested in their portfolio companies for a substantial period of time after the IPO, and that the choice of a given exit strategy depends not only upon the characteristics of each respective portfolio company, but also on the financial success of the deal from the perspective of the buyout investor.     

On the Closeness Aspect of Three Voting Rules: Borda – Copeland – Maximin

This paper provides a comparison of three voting rules, the Borda rule, the Copeland rule and the maximin rule. Our analysis based on the rankings derived from those voting rules will shed new light on existing comparisons based on “closeness” between the three voting rules under investigation. In particular it will be shown that both, the rankings derived from the Borda rule and the maximin rule and the rankings derived from the Copeland rule and the maximin rule, will be exactly the opposite for certain preference profiles.

Clustering Biotech: A Recipe for Success? Spatial Patterns of Growth of Biotechnology in Munich,Rhineland and Hamburg

The dynamic growth of biotechnology in Germany in recent years has an obviously spatial pattern. Some regions show a substantial potential for start-ups and young firms of this new industry whereas others lag behind. The paper is discussing this unequal spatial development elaborating perspectives which derive from recent debates about regional innovation systems. The biotech regions Munich and Rhineland, both winner regions of the BioRegio Competition are described and compared with the situation in Hamburg where biotechnology is much less important. We analyze the degree and relevance of locally integrated input-output relations of innovation systems based on typologies of the wide range of firms within the biotechnological value chain and the forms of co-operation. Moreover, a qualitative estimate is given with respect to the significance of untraded relationships and regional knowledge spillovers. Factors favoring local integration are compared with those favoring input-output systems on a transatlantic scale. The paper discusses the question whether the biotech industries in the regions of Munich, Rhineland and Hamburg represent identifiable regional systems of innovation.Our findings show that the spatial concentration does not necessarily imply a close network of input-output relations within a cluster. Knowledge and technology transfer often happens on a international, mostly on the North Atlantic scale. The exchange of tacit knowledge, however, is facilitated by spatial proximity. This underlines the importance of untraded relations and "relational assets" in a region. Political and institutional support for building a "business community" can reduce barriers to launch risky commercialization processes.
