We analyze the implications of the structure of a network for asset prices in a general equilibrium model. Networks are represented via self- and mutually exciting jump processes, and the representative agent has Epstein-Zin preferences. Our approach provides a flexible and tractable unifying...

This paper provides empirical evidence on initial public offerings (IPOs) by investigating the pricing and long-run performance of IPOs using a unique data set collected on the German capital market before World War I. Our findings indicate that underpricing of IPOs has existed, but has...

This paper provides empirical evidence on initial returns and long-run performance of initial public offerings (IPOs) in Germany before World War I. In the literature it is often argued that a check for the robustness of existing results should be undertaken using different data sets and periods...

We study the method proposed by Flood and Rose (FR, 2004, 2005) for checking for financial integration by estimating the risk-free rate using the idiosyncratic component of individual stock returns. Performing simulations with data with a known return generation process, we find that the FR...

Tests for the existence and the sign of the volatility risk premium are often based on expected option hedging errors. When the hedge is performed under the ideal conditions of continuous trading and correct model specification, the sign of the premium is the same as the sign of the mean hedging...

When options are traded, one can use their prices and price changes to draw inference about the set of risk factors and their risk premia. We analyze tests for the existence and the sign of the market prices of jump risk that are based on option hedging errors. We derive a closed-form solution...

In this paper we study the equilibrium in a heterogeneous economy with two groups of investors. Over-confident experts incorrectly assume that their signal for the drift of the dividend process is correlated with the true drift, but interpret the signal otherwise perfectly. Rational laymen avoid...

Variance contracts permit the trading of 'variance risk', i.e. the risk that the (squared) volatility of stock returns changes randomly over time. We discuss why investors might want to trade this type of risk, and why they might prefer a variance contract to standard calls and puts for this...
