Estimation Uncertainty in Credit Risk Assessment: Comparison of Credit Risk Using Bootstrapping and an Asymptotic Approach
Henry Dannenberg
IWH Discussion Papers,
No. 3,
2009
Abstract
For credit risk assessment, probability of default and correlation have to be estimated simultaneously. However, these estimates are uncertain. To assess this uncertainty the literature has discussed the use of asymptotic confidence regions. This kind of region though needs a long credit history for exact assessment. An alternative method to generate a confidence region for a short credit history is bootstrapping. Hence, it could be more appropriate to assess estimation uncertainty with bootstrapping than with asymptotic methods if only a short credit history is available. Based on a simulation study, it is analyzed how many periods should be available for assessing credit risk – taking account of estimation uncertainty – if bootstrapping and a Wald confidence region shall achieve similar results. This article shows that more than 100 cycles have to be available for similar results.

Determinants of Academic-Industry Linkages and Incubator-internal Cooperation Patterns of Incubator Firms: Empirical Evidence from Germany
Michael Schwartz, Christoph Hornych
IWH Discussion Papers,
No. 2,
2009
Abstract
The article examines cooperation patterns of firms located in German business incubators (BIs) and technology centers. Based on cross-sectional data, the study explores the network activities within the tenant portfolio and the academic-industry linkages of the tenant firms. In this respect, we contribute to the literature on the impact of business incubation by explicitly considering differences regarding cooperation patterns between diversified and specialized incubator facilities. Contrary to common assumptions, we do not find a higher propensitiy for incubator-internal cooperation activities for firms located in specialized BIs. However, firms located in specialized BIs show significantly higher propensity to engage in academic-industry linkages compared to firms located in diversified incubators.

Contestability, Technology and Banking
S. Corvoisier, Reint E. Gropp
ZEW Discussion Papers, No. 09-007,
No. 7,
2009
Abstract
We estimate the effect of internet penetration on retail bank margins in the euro area. Based on an adapted Baumol [1982] type contestability model, we argue that the internet has reduced sunk costs and therefore increased contestability in retail banking. We test this conjecture by estimating the model using semi-aggregated data for a panel of euro area countries. We utilise time series and cross-sectional variation in internet penetration. We find support for an increase in contestability in deposit markets, and no effect for loan markets. The paper suggests that for time and savings deposits, the presence of brick and mortar bank branches may no longer be of first order importance for the assessment of the competitive structure of the market.

Abstract
On the basis of a neoclassical production function in a small open economy the contribution shows potential economic effects of population and workforce ageing and shrinking. Some evidence is provided, that ageing and not shrinking is the true burden of demographic change.
