We consider a random utility extension of the fundamental Lucas (1978) equilibrium asset pricing model. The resulting structural model leads naturally to a likelihood function. We estimate the model using U.S. asset market data from 1871 to 2000, using both dividends and earnings as state...

This paper approximation errors are introduced in a Luca (1978)-type model to reflect model uncertainty. The purpose is twofold. First, the rational investor is allowed to take model uncertainty into account when asset prices are determined. Second, the statistical degeneracy, common to most...

This paper suggests a method for determining rigorous upper bounds on approximation errors of numerical solutions to infinite horizon dynamic programming models. Bounds are provided for approximations of the value function and the policy function as well as the derivatives of the value function....

Kinks and jumps in the payoff function of option contracts prevent an effective implementation of higher-order numerical approximation methods. Moreover, the derivatives (the greeks) are not easily determined around such singularities, even with standard lower-order methods. This paper suggests...

This paper considers estimation of a pure equilibrium search model in which all heterogeneity is endogenous and due to information asymmetries, and of variations that allow better fits to the data. Measurement error and heterogeneity in the productivity levels of firms. The model is fit to a...

We consider the relation between the volatility implied in an option's price and the subsequently realized volatility. Earlier studies on stock index options have found biases and inefficiencies in implied volatility as a forecast of future volatility. More recently, Christensen and Prabhala...

We examine the forward market for electricity for indications of misuse of market power. The data source is a unique set of OTC price indications posted by Elsam A/S, the dominant producer in Western Denmark, which is one of the price areas under the Nordic power exchange Nord Pool. The Danish...
