I assess the impact of increasing the tick size on stock liquidity and trading volume in illiquid stocks. Using a regression discontinuity design at the Oslo Stock Exchange, I find that increasing the tick size has no impact on the transaction costs, order book depths, or trading volumes of...

We derive invariance relationships in a dynamic, infinite-horizon, equilibrium model of adverse selection with risk-neutral informed traders, noise traders, market makers, and with endogenous information production. The model solution depends on two state variables: stock price and...

We propose a partitioning algorithm to solve a class of linear-quadratic Markov decision processes with inequality constraints and non-convex stage-wise cost; within each region of the partitioned state space, the value function and the optimal policy have analytical quadratic and linear forms,...

We model a financial market where privately informed investors trade in a limit order book monitored by professional liquidity providers. Price competition between informed limit order submitters and professional market makers allows us to capture tradeoffs between informed limit and market...

This paper studies the relation between intermarket sweep order, ISO, order imbalances and daily returns of individual stocks. I show that ISO order imbalances positively affect contemporaneous returns. Second, I find that price pressures emanating from ISO imbalances are persistent and result...

This paper examines the effects of multimarket high-frequency trading (HFT) activity on liquidity co-movements across different markets. Multimarket trading by HFTs connects individual markets in a single network, which should induce stronger network-wide liquidity co-movements. We use the...

This paper builds the clustering model of measures of market microstructure features which are popular in predicting the stock returns. In a 10-second time frequency, we study the clustering structure of different measures to find out the best ones for predicting. In this way, we can predict...

This chapter investigates the influence of improved pre-trade transparency on the information content of the limit order book. Data from two natural experiments are examined: when the Sydney Futures Exchange increased the limit order book disclosure from the best bid and ask level to the best...

This paper studies invariance relationships in tick-by-tick transaction data in the U.S. stock market. Over the 1993–2001 period, the estimated monthly regression coefficients of the log of trade arrival rate on the log of trading activity have an almost constant value of 0.666, strikingly...
