Close-to-zero interest rates challenge standard economic models in which zero lower bound (ZLB) is absent. We estimate a recursive utility model which features time-varying latent expected real growth, expected inflation, and stochastic inflation volatility. Using an approximate solution to bond...

This paper deals with the superhedging of derivatives on incomplete markets, i.e.with portfolio strategies which generate payoffs at least as high as that of a givencontingent claim. The simplest solution to this problem is in many cases a staticsuperhedge, i.e. a buy-and-hold strategy...

This paper deals with the superhedging of derivatives and with the corresponding price bounds. A static superhedge results in trivial and fully nonparametric price bounds, which can be tightened if there exists a cheaper superhedge in the class of dynamic trading strategies. We focus on European...

Zinsderivate wie Swaps, Caps, Forwards oder Futures ermöglichen auf vielfältige Weise das Management von Zinsrisiken. Die Bewertung dieser Kontrakte erscheint jedoch meist wesentlich schwieriger und anspruchsvoller als die Bewertung von Aktien- oder Währungsderivaten, da Anleihen besondere...

We perform a general equilibrium analysis in a complete markets economy whenthe dividend follows a jump-diffusion process with stochastic volatility. Agents haveCRRA utility, but differ with respect to their degree of risk aversion. The keyoutput of our analysis is the structure of the...

We consider an exchange economy with two heterogeneous stocks and twogroups of investors. Dividends follow diusion processes, with a constant expectedgrowth rate for one stock and a stochastic drift for the other. 'Rationalinvestors' can either observe this stochastic drift without error or...

In this paper we perform a general equilibrium analysis when the dividend followsa jump-diffusion process with stochastic volatility, where both the dividend itselfand its volatility can jump. We work in a complete markets economy and assumethat agents have CRRA utility, but can differ with...
