We investigate empirically the impact of electronic market-makers on the reliability and the consistency with which financial markets provide transactional liquidity services. Our analysis is based on proprietary intraday data from U.S. futures markets. We document results of considerable...

In this paper we develop a new approach to understanding the behavior of high frequency electricity spot prices. It treats electricity delivered at different times of the day as different commodities, while recognizing that these commodities may be traded on a small number of intra-day markets....

This paper uses high frequency wholesale electricity spot price data from Australia, Canada, and the United States to estimate realized volatility and the frequency of price spikes. I find similar levels of realized volatility in Australia and North America, with estimates ranging from 1,500% to...

In this paper we estimate the skewness of the marginal distribution of energy returns and test its statistical significance. We use traditional tests of symmetry but we also estimate a TGARCH model assuming a Gram-Charlier distribution for the innovations. Our results show that crude oil (Brent...

We examine the impact of oil price and oil price volatility on US illiquidity premiums (return on illiquid-minus-liquid stocks), using the US Oil Fund options implied volatility OVX index. We use daily data from 2007 to 2018, taking into account the structural break in June 2009 and controlling...

This study attempts to discover the nexus between crude oil price fluctuation after heavy oil upgrading and stock returns of petroleum companies in the U.S. Stock Exchange for the years 2008 to 2018. One of the methods of upgrading heavy crude oil is to extract asphaltene from crude oil....

We propose a comprehensive treatment of the leverage effect, i.e. the relationship between returns and volatility of a specific asset, focusing on energy commodities futures, namely Brent and WTI crude oils, natural gas and heating oil. After estimating the volatility process without assuming...

Motivated by repeated spikes and crashes during previous decades we investigate whether the heavily financialized market for crude oil has been driven by speculative bubbles. In our theoretical modeling we draw on the convenience yield approach in order to approximate the fundamental value of...

This study investigates the dynamics of stock market liquidity in the energy industry in the US for 130 firms for the period 2006–2011. We use a (structural) vector autoregression approach to model the simultaneous relationships between three liquidity measures, namely turnover, price impact...
