We integrate liquidity risk measured by the weighted spread into a Value-at-Risk (VaR) framework. The weighted spread … measure extracts liquidity costs by order size from the limit order book. We show that it is precise from a risk perspective … find liquidity risk to increase traditionally-measured price risk by over 25%, even at standard 10-day horizons and for …

A long tradition in macro finance studies the joint dynamics of aggregate stock returns and dividends using vector autoregressions (VARs), imposing the cross-equation restrictions implied by the Campbell-Shiller (CS) identity to sharpen inference. We take a Bayesian perspective and develop...

We revisit the question whether commodities should be included in investors' portfolios. We employ for the first time a stochastic dominance efficiency (SDE) approach to construct optimal portfolios with and without commodities and we evaluate their comparative performance. SDE circumvents the...

We develop likelihood-based tests for autocorrelation and predictability in a first order non-Gaussian and noninvertible ARMA model. Tests based on a special case of the general model, referred to as an all-pass model, are also obtained. Data generated by an all-pass process are uncorrelated...
