Bedingte Aktiengeschäfte sind solche, die nur bei Eintritt einer Bedingung wirksam werden, z. B. bei einer Übernahme oder der Wahl eines bestimmten Vorstandsvorsitzenden. Damit lassen sich Alternativen bewerten und Entscheidungen besser treffen.

We discover a novel monetary policy shock that has a widespread impact on aggregate financial conditions. Our shock can be summarized by the response of long-horizon yields to Federal Open Market Committee (FOMC) announcements; not only is it orthogonal to changes in the near-term path of policy...

We characterize how informed investors trade in the options market ahead of corporate news when they receive private, but noisy, information about (i) the timing of the announcement and (ii) its impact on stock prices. Our theoretical framework generates a rich set of predictions about the...

Using merger announcements and applying methods from computational linguistics we find strong evidence that stock prices underreact to information in financial media. A one standard deviation increase in the media-implied probability of merger completion increases the subsequent 12-day return of...

In inefficient stock markets payout policy may be directly relevant for stock prices, not only by way of announcement effects considered in signaling games. We show that paying out free cash flow, either as a dividend or via repurchasing shares, has in general a positive price impact and...

Futures markets are a potentially valuable source of information about price expectations. Exploiting this information has proved difficult in practice, because time-varying risk premia often render the futures price a poor measure of the market expectation of the price of the underlying asset....

In a dynamic stochastic exchange economy where, due to beliefs heterogeneity, agents engage in speculative trade, I investigate the Market Selection Hypothesis that speculation rewards the agent with the most accurate beliefs. Assuming that agents maximize Epstein-Zin preferences and that...

This paper examines whether investor mood, driven by World Health Organization (WHO) alerts and media news on globally dangerous diseases, is priced in pharmaceutical companies' stocks in the United States. We concentrate on irrational investors who buy and sell pharmaceutical companies' stocks...

We analyse whether different levels of country ties to Europe among the rating agencies Moody's, S&P, and Fitch affect the assignment of sovereign credit ratings, using the Eurozone sovereign debt crisis of 2009-2012 as a natural laboratory. We find that Fitch, the rating agency among the "Big...

We examine whether there is contagion from the U.S. stock market to six Central and Eastern European stock markets. We use a novel measure of contagion that examines whether volatility shocks in the U.S. stock market coupled with negative returns are followed by higher co-exceedance between U.S....
