About the paper
This paper examines the effects of banning and/or heavily regulating dark pools on European trading activity and overall market quality following the announcement and implementation of MiFID II, the DVC (double volume caps) and MiFIR by the European Commission.
The research was primarily looking to discover where traders migrate following implementation of regulations, and the key implications for primary market liquidity and efficiency. It did so through a Quasi-Experimental approach, looking at Semiparametric Difference-in-Differences, Regression Discontinuity Design, analysis of stock that were incorrectly not banned due to failed reporting, and the effect on the market of announcement.
The research observed Liquidity, Market Shares, and Price Efficiency over key trading formats including Dark LIS, Periodic Auctions, Continuous Lit trading, Call Auctions, SI (systematic internalisers) and OTC (over the counter / off-exchange trading), tracking relative Tick size, Tick Constraint, log MV, Reference Price Waiver and Unconditional.
