We show that wealth processes in the block-shaped order book model of Obizhaeva/Wang converge to their counterparts in the reduced-form model proposed by Almgren/Chriss, as the resilience of the order book tends to infinity. As an application of this limit theorem, we explain how to reduce...

Since European trading now traverses national boundaries, and MTFs are rampant, how have the stock price dynamics changed? Analysing the execution channels NYSE Euronext Paris, Chi-X and BATS in CAC40 stocks, we compare metrics of market efficiency pre/post-MiFID and provide insight into the...

We continue the analysis of optimal execution strategies in the model for a limit order book with nonlinear price impact and exponential resilience that was considered in Alfonsi, Schied, and Fruth (2009). We now allow for non-homogeneous resilience rates and arbitrary trading dates and consider...

This paper studies the workup protocol, a unique trading feature in the U.S. Treasury securities market that resembles a mechanism for discovering dark liquidity. We quantify its role in the price formation process in a model of the dynamics of price and segmented order flow induced by the...

Firms changing their listing from the less regulated AIM to the more regulated main section of the London Stock Exchange exhibit positive returns on the day the decision is announced, while for firms moving in the opposite direction both announcement and implementation day returns are negative....

China launched a pilot scheme in March 2010 to lift the ban on short-selling and margin-trading for stocks on a designated list. We find that stocks experience negative returns when added to the list. After the ban is lifted, price efficiency increases while stock return volatility decreases....

We document the changes in dynamic stochastic structure of the various industrial sectors of the Chinese A, B share markets and the Hong Kong share markets. We utilize a robustly estimated VECM-MV-GARCH model to test for possible co-integrating vectors between the market segmentations pre and...

Despite the growing adoption of decentralized exchanges, little is known about their market quality. Using a comprehensive dataset, we compare decentralized blockchain-based venues (DEXs) to centralized crypto exchanges (CEXs) assessing two aspects of market quality: price efficiency and market...
