Although the main interest in the modelling of electricity prices is often on volatility aspects, we argue that stochastic heteroskedastic behaviour in prices can only be modelled correctly when the conditional mean of the time series is properly modelled. In this paper we consider different...

We consider eight different measures (issued amount, coupon, listed, age, missingprices, price volatility, number of contributors and yield dispersion) to approximate corporatebond liquidity and use a five-variable model to control for maturity, credit and currencydifferences between bonds. The...

We investigate the effects of introducing a central clearing counterparty (CCP) on securities prices by adopting as an experimental construct the 2009 CCP reform in three Nordic markets. We find that, relative to other European economies, these countries experience market-adjusted equity returns...

I study a model of market-liquidity provision by levered intermediaries that, besides operating trading desks, run deposit-taking franchises. Levered intermediaries’ heightened incentive to absorb risk helps to counteract liquidity-provision frictions that, in an unlevered economy, would lead...

We examine whether the drastic improvement in liquidity in the US stockmarket after 2003 has impacted the systematic exposures of hedge funds to theUS-stock market. The relation between market exposure and Amihud’s illiquiditymeasure reverses significantly around a breakpoint situated...

This paper argues that the introduction of a short-sale constraint in the Arrow-Radner frameworkinvalidates standard definitions of complete and incomplete markets. In this constrained set-up,two threshold values with familiar properties arise.The case of a zero short-sale bound set on some...

Speeding up the exchange does not necessarily improve liquidity. The price quotes of high-frequency market makers are more likely to meet speculative high-frequency "bandits", thus less likely to meet liquidity traders. The bid-ask spread is raised in response. The recursive dynamic model...

Taking a portfolio perspective on option pricing and hedging, we show that within the standard Black-Scholes-Merton framework large portfolios of options can be hedged without risk in discrete time. The nature of the hedge portfolio in the limit of large portfolio size is substantially different...

The equity premium is a key parameter in asset allocation policies. There is a vigorous debate in the literature regarding the actual measurement of the equity premium, its size and the determinants of its variation. This study aims to take stock of this literature by means of a meta-analysis....
