We study the distinct impacts of own and rival actions on risk and return when firms strategically compete in the product market. Contrary to simple intuition, a competitor's options to adjust capacity reduce own-firm risk. For example, if a rival possesses a growth option, an increase in...

We examine a model in which two firms strategically compete in a duopolistic product market. Firms produce a homogenous product and face stochastic industry demand. Each firm has a single option either to expand or contract capacity, and hence output. In this setup we analyze the risk...

Credit risk has become an important factor driving government bond returns. We therefore introduce an asset pricing model which exploits information contained in both forward interest rates and forward CDS spreads. Our empirical analysis covers euro-zone countries with German government bonds as...

Many economic problems can be formulated as dynamic games in which strategically interacting agents choose actions that determine the current and future levels of a single capital stock. We study necessary conditions that allow us to characterize Markov perfect Nash equilibria (MPNE) for these...

Aufbauend auf einem klassischen Finanzmarktmodell behandeln wir drei Modellvarianten, die jeweils einen anderen Ansatz der (heterogenen) Erwartungsbildung von Investoren über künftige Wertpapierpreise in den Vordergrund der Betrachtungen rücken: das Konzept der konsistenten Erwartungen, das...

The widespread use of accounting information by investors and financial analysts to help value stocks creates an incentive for managers to manipulate earnings in an attempt to influence short-term stock price performance. This paper examines the role of earnings management in affecting a firm's...

The paper examines the tendency to sell winners and hold on to losers in a dynamic noisy rational expectations equilibrium with informed and uninformed investors. The key feature of the model is that the information asymmetry between investors varies over time. Besides demonstrating that the...
