We aim at accommodating the existing affine jump-diffusion and quadratic models under the same roof, namely the linear-quadratic jump-diffusion (LQJD) class. We give a complete characterization of the dynamics of this class by stating explicitly the structural constraints, as well as the...

This paper investigates the relative influences of industrial and country factors in international stock returns. Until very recently, academic research has consistently found that country factors dominate industrial factors. This result is in contradiction with practitioners beliefs. This paper...

n this study, we examine the level of stock market integration and the impact of sovereign risk on the pricing of European equity markets since the introduction of the euro. We use a multivariate GARCH(1,1)-M return generating model allowing for partial market integration in which sovereign risk...

We explain excess volatility, short-term momentum and long-term reversal of asset prices by a repeated game version of Keynes beauty contest. In every period the players can either place a buy or sell order on the asset market. The actual price movement is determined by average market orders and...

This paper introduces state dependent utility into the standard Mehra and Prescott (1985) economy by allowing the representative agents coefficient of relative risk aversion to vary with the underlying economys growth rate. Existence of equilibrium is proved and its asymptotic properties...

We investigate the influence of various variables on credit default swap transaction data. Credit derivatives are arguably a superior proxy to credit risk than bond spreads. The variables considered include fixed-income as well as equity markets data. We thus provide an international analysis of...

In this paper we study the hedging of derivatives in illiquid markets. More specifically we consider a model where the implementation of a hedging strategy affects the price of the underlying security. Following earlier work we characterize perfect hedging strategies by a nonlinear version of...

This paper presents a new method to detect informed trading activities in the options markets.An option trade is identified as informed when it is characterized by an unusual largeincrement in open interest and volume, induces large gains, and is not hedged in the stock market.For the period...
