Volatility risk premia compensate agents for holding assets whose payoffs correlate with times of high return variation …. This paper takes a structural approach to explain the cross-section of volatility risk premia of stocks using a Lucas … uncertainty, namely (i) agents’ disagreement and (ii) time-varying volatility of fundamental growth rates. The paper shows that …

Several authors have proposed series expansion methods to price options when the risk-neutral density is asymmetric and leptokurtic. Among these, Corrado and Su (1996) provide an intuitive pricing formula based on a Gram-Charlier Type A series expansion. However, their formula contains a...

We investigate a class of semiparametric ARCH(∞) models that includes as a special case the partially nonparametric (PNP) model introduced by Engle and Ng (1993) and which allows for both flexible dynamics and flexible function form with regard to the 'news impact' function. We propose an...

Ambivalence in the regulatory definition of capital adequacy for credit risk has recently stirred the financial services industry to collateral loan obligations (CLOs) as an important balance sheet management tool. CLOs represent a specialised form of Asset-Backed Securitisation (ABS), with...

Following the framework of Cetin et al. (finance stoch. 8:311-341, 2004), we study the problem of super-replication in the presence of liquidity costs under additional restrictions on the gamma of the hedging strategies in a generalized black-scholes economy. We find that the minimal...

We provide a test of the Monday effect in daily stock index returns. Unlike previous studies we define the Monday effect based on the stochastic dominance criterion. This is a stronger criterion than those based on comparing means used in previous work and has a well defined economic meaning. We...

This paper reviews fundamental concepts in environmental economics and explores theoretical results regarding the choice of the key policy instruments for the control of externalities: taxes, subsidies and marketable permits. The paper explains why today market mechanisms are increasingly being...

Equilibrium models have been proposed in literature with the aim of describing the evolution of the price of emission permits. This paper derives first a reducedform model from an equilibrium model and thereby explains how existing reducedform models are related to equilibrium models. Second, by...
