In this article, we formulate a semiparametric model for counting processes in which the effect of covariates is to transform the time scale for a baseline rate function. We assume an arbitrary dependence structure for the counting process and propose a class of estimating equations for the...

[This item is a preserved copy. To view the original, visit http://econtheory.org/] We study a game of strategic experimentation with two-armed bandits where the risky arm distributes lump-sum payoffs according to a Poisson process. Its intensity is either high or low, and unknown to the...

The number of bank failures has increased dramatically over the last twenty-two years. A common notion in economics is that some banks can become "too big to fail." Is this still a true statement? What is the relationship, if any, between bank sizes and bank failures? In this thesis, the...

Die Arbeit beschäftigt sich mit der Investition in neue, emissionsärmere Technologien, bei dem der Entscheider eine große, langfristige Investition tätigt und den dafür optimalen Zeitpunkt wählt. Dabei wird sowohl der gesamtwirtschaftliche Kontext, also die effiziente Allokation der neuen...

The research presented in this thesis addresses different aspects of dynamic portfolio construction and portfolio risk measurement. It brings the research on dynamic portfolio optimization, replicating portfolio construction, dynamic portfolio risk measurement and volatility forecast together....

Since the mid-nineties, agricultural economists discuss the suitability of “weather derivatives” as hedging instruments for volumetric risks in agriculture. Contrary to traditional insurance contracts, the payoffs of such derivatives are linked to weather indices (e.g. accumulated rainfall...

In this paper, we propose a framework for robust optimization that relaxes the standard notion of robustness by allowing the decision maker to vary the protection level in a smooth way across the uncertainty set. We apply our approach to the problem of maximizing the expected value of a payoff...

An analysis and further development of the building blocks of modern credit risk management:- Definitions of default- Estimation of default probabilities- Exposures- Recovery Rates- Pricing- Concepts of portfolio dependence- Time horizons for risk calculations- Quantification of portfolio risk-...

The traditional Markowitz mean-variance portfolio optimization theory uses volatility as the sole measure of risk. However, volatility is flawed both intuitively and theoretically: being symmetric it does not differentiate between gains and losses; it does not satisfy an expected utility...
