This paper contributes to the ongoing debate on the relationship between austerity measures and economic growth. We propose a general equilibrium model where (i) agents have recursive preferences; (ii ) economic growth is endogenously driven by investments in R&D; (iii) the government is...

We analyze the equilibrium in a two-tree (sector) economy with two regimes. The output of each tree is driven by a jump-diffusion process, and a downward jump in one sector of the economy can (but need not) trigger a shift to a regime where the likelihood of future jumps is generally higher....

We study self- and cross-excitation of shocks in the Eurozone sovereign CDS market. We adopt a multivariate setting with credit default intensities driven by mutually exciting jump processes, to capture the salient features observed in the data, in particular, the clustering of high default...

This paper uses analysts' forecasts to estimate a share's equity duration, a measure of a company's average cash-flow maturity. We find that short duration equity is associated with high expected and realized returns, which cannot be attributed to the shares' systematic risk exposure as implied...

In diesem Beitrag wird untersucht, ob die Einführung der Wertpapier-KESt zum 1. Jänner 2011 einen signifikanten Einfluss auf das Handelsvolumen am österreichischen Kapitalmarkt hatte. Basierend auf der Annahme, dass Investoren die Information über die Einführung der Wertpapier-KESt zum...

The paper studies the effect of uncertainty in tax avoidance on firm value. We first show in a clean surplus valuation model that expected tax rates interact with expectations about future profitability. This paper builds and tests a valuation framework that incorporates two outcome dimensions...

Let Q be the set of equivalent martingale measures for a given process S, and let X be a process which is a local supermartingale with respect to any measure in Q. The optional decomposition theorem for X states that there exists a predictable integrand ф such that the difference X−ф•S is...

In a complete financial market every contingent claim can be hedged perfectly. In an incomplete market it is possible to stay on the safe side by superhedging. But such strategies may require a large amount of initial capital. Here we study the question what an investor can do who is unwilling...

This paper is devoted to the problem of hedging contingent claims in the framework of a complete two-factor jump-diffusion model. In this context, it is well understood that every contingent claim can be hedged perfectly if one invests the unique arbitrage-free price. Based on the results of H....

An investor faced with a contingent claim may eliminate risk by (super-)hedging in a financial market. As this is often quite expensive, we study partial hedges, which require less capital and reduce the risk. In a previous paper we determined quantile hedges which succeed with maximal...
