In this paper, we investigate the importance of different loss functions when estimating and evaluating option pricing models. Our analysis shows that it is important to take into account parameter uncertainty, since this leads to uncertainty in the predicted option price. We illustrate the...

We analyse the effects of insider trading on real investment and welfare, and the consequences of different regulatory policies: a disclose-or-abstain rule, ‘fair’ disclosure, laissez-faire and forbidding insider trades based on ‘precise’ information. We perform the analysis in a model...

The paper evaluates the ability of asset pricing models that do not use consumption data, and models that use consumption data as a proxy for true consumption, to explain the time-series and cross-sectional variation of expected returns of portfolios of stocks. Although some parameter...

This Paper studies predatory trading: trading that induces and/or exploits other investors’ need to reduce their positions. We show that if one trader needs to sell, others also sell and subsequently buy back the asset. This leads to price overshooting and a reduced liquidation value for the...

In the last few years, the empirical literature has documented that existing correlations between national returns are higher than correlations between the national growth rates of fundamental variables. In this paper we study the ability of intertemporal asset pricing models to explain...

Surprisingly there are very few estimates of the equity risk premium period-by-period that satisfy a no-arbitrage condition, despite the vast literature on the subject. This is mainly due to the difficulties of estimation. Using the stochastic discount factor (SDF) model based on observable...

The theory and the data in this Paper challenge the view that there is no structure in prices and allocations when markets are off equilibrium. Starting from the observation that price-taking usually applies only to small orders, a theory of equilibration is derived based on the assumption that...

This study investigates whether market-wide liquidity is a state variable important for asset pricing. We find that expected stock returns are related cross-sectionally to the sensitivities of returns to fluctuations in aggregate liquidity. Our monthly liquidity measure, an average of...

This paper considers the evidence for volatility clustering and transmission in six bilateral Deutsche mark ERM exchange rates. Data on daily exchange rate changes are described by a mixture of two normal distributions. One of these contains observations of volatile exchange rate changes while...

Consumption is striking back. Some recent evidence indicates that the well-known asset pricing puzzles generated by the difficulties of matching fluctuations in asset prices with high frequency fluctuations in consumption might be solved by considering consumption in the long-run. A first strand...
