A popular interpretation of the Rational Expectations/Efficient Markets hypothesis states that, if the hypothesis holds, then market valuations must follow a random walk. This postulate has frequently been criticized on the basis of empirical evidence. Yet the assertion itself incurs what we...

Based on criteria of mathematical simplicity and consistency with empirical market data, a stochastic volatility model is constructed, the volatility process being driven by fractional noise. Price return statistics and asymptotic behavior are derived from the model and compared with data....

Alan Greenspan's paper (March 2010) presents his retrospective view of the crisis. His theme has several parts. First, the housing price bubble, its subsequent collapse and the financial crisis were not predicted either by the market, the FED, the IMF or the regulators in the years leading to...

This paper provides micro-econometric evidence on the relevance of non-market interaction for the timing of initial public offerings (IPOs) in the French and German primary equity markets. The surge of IPO volume in the late 1990s appears to be consistent with rational expectations, not with...

We use weekly survey data on short-term and medium-term sentiment of German investors in order to study the causal relationship between investors' mood and subsequent stock price changes. In contrast to extant literature for other countries, a tri-variate vector autoregression for short-run...

This paper offers a quantitative description of European private equity markets and compares the recent development in these markets with the development of the US venture capital market. Moreover, the paper addresses the differences between private equity investors acting in a single national...

The relationship between a venture capitalist and an entrepreneur is modeled to investigate the impact of public subsidies on venture capital investments in start-up enterprises. In this model, the venture capitalist only finances start-up enterprises if he has sufficient expertise to make...

This paper surveys empirical and theoretical studies of various control mechanisms embedded in venture capital contracts. These mechanisms mitigate incentive problems and opportunistic behavior arising in the uncertain environment of financing young high-technology enterprises that predominantly...

This paper analyses the link between venture capitalists’ sources of funds, such as banks and pension funds, and the specialization pattern of venture capital investments in particular industries and particular stages of enterprises’ development. Based on a panel data set of Western European...
