Using unique transactions data for individual high-frequency trading (HFT) firms in the UK equity market, we examine if the trading activity of individual HFT firms is contemporaneously and dynamically correlated with each other, and what impact this has on price efficiency. We find that HFT...

We analyse liquidity dynamics in the UK long gilt futures market. We use a novel order book dataset to assess liquidity resilience to sources of pressure such as policy operations or episodes of financial distress. Our results provide evidence in favour of resilience. We further show that this...

This paper uses transaction data to estimate how single stock circuit breakers on the London Stock Exchange affect other stocks that remain in continuous trading. This ‘spillover' effect is estimated by calculating the effect of a trading halt on the market quality of stocks that remain in...

In a world of interconnected financial markets it is plausible that risk appetite — an important factor in asset pricing — is determined globally. By constructing an estimate of variance risk premia (VRP) for UK, US and euro-area equity markets, we are able to estimate international variance...

This paper proposes a novel approach to assessing volatility contagion across equity markets. I decompose the variance risk premia of three major stock indices into: crash and non-crash risk components and analyse their cross-market correlations. I find that crash-risk premia exhibit higher...

This paper studies how non-Gaussian shocks affect risk premia in DSGE models approximated to second and third order. Based on an extension of the work by Schmitt-Grohe and Uribe to third order, we derive propositions for how rare disasters, stochastic volatility, and GARCH affect any risk premia...

This paper studies the causal effects of personal investment taxes on stock demand, stock returns, and the financial decisions of companies. I exploit a change in legislation in 2013 which allowed stocks listed on the Alternative Investment Market, a sub-market of the London Stock Exchange, to...

This paper is about the effectiveness of qualitative easing, a form of unconventional monetary policy that changes the risk composition of the central bank balance sheet with the goal of stabilizing economic activity. We construct a general equilibrium model where agents have rational...
