In this paper we 'update' the option implied probability of default (option iPoD) approach recently suggested in the literature. First, a numerically more stable objective function for the estimation of the risk neutral density is derived whose integrals can be solved analytically. Second, it is...

Rating downgrades are known to make subsequent downgrades more likely. We analyze the impact of this ?downward momentum? on credit portfolio risk. Using S&P ratings from 1996 to 2005, we estimate a transition matrix that is insensitive to and a second matrix that is sensitive to previous...

The underpricing phenomenon of Initial Public Offerings (IPOs) has been widely studied across different stock markets around the world and has often been explained to be as a result of asymmetrically distributed information and ex-ante uncertainty. However, as Ritter and Welch (2002) argue to...

The overallotment or greenshoe option has become very popular in the German IPO market since its introduction in 1995 and is nowadays an important tool to stabilize IPOs or to issue additional shares in the case of excess demand. Besides providing evidence for the prevalence of price support...

Using a unique, hand-collected database of all venture- backed firms listed on Germany's Neuer Markt, we analyze the history of venture capital financing of these firms before the IPO and the behavior of venture capitalists at the IPO. We can detect significant differences in the behavior and...

In this paper, we analyze the investment and divestment patterns of different types of venture capitalists. Using a data set em- bracing all venture-backed IPOs that occurred on Germany's Neuer Markt we investigate whether the governance structures, objectives, abilities and track records of...

This paper sets out to analyze the influence of different types of venture capitalists on the performance of their portfolio firms around and after IPO. We investigate the hypothesis that different governance structures, objectives, and track records of different types of VCs have a significant...

Venture capital markets are characterized by multiple incentive problems and asymmetric information in an uncertain environment. All kinds of agency problems are present: moral hazard, adverse selection, hold-up problems, window dressing, etc. Entrepreneurs and venture capitalists enter into...

We present evidence on venture capitalists? (VCs) impact on turnover of executives for a sample of nearly 47,000 German high-tech start-ups between 1995 and 2004. We confirm that the presence of VCs increases the probability of a change in the initial executive team. Additionally, we take a...

We analyze the venture capitalist's decision on the timing of the IPO, the offer price and the fraction of shares he sells in the course of the IPO. A venture capitalist may decide to take a company public or to liquidate it after one or two financing periods. A longer venture capitalist's...
