We analyse the price discovery process in DJIA stocks before and after the full implementation of Reg NMS in October 2007. The execution channels analysed are NYSE-ARCA, the traditional NYSE system, and NASDAQ. By comparing the changes in Hasbrouck's information share to changes in the...

In November 2008, the Federal Reserve announced the first of a series of unconventional monetary policies, which would include asset purchases and forward guidance, to reduce long-term interest rates. We investigate the behavior of shorts, considered sophisticated investors, before and after a...

In 2015 the Tokyo Stock Exchange (TSE) implemented Arrowhead Renewal improvements (ARI) that reduced latency from about one millisecond to less than 0.5 milliseconds. Simultaneously, the ARI introduced new risk management functions to improve market fairness by reducing manipulative trading...

We investigate the impact of failures-to-deliver on the performance of 116 Real Estate Investment Trusts (REITs) during a period of substantial short selling (calendar years 2007 and 2008). REIT shares typically are easy to borrow, have high transparency (low information asymmetry), and are...

We investigate competition between traditional stock exchanges and new ‘dark' trading venues using an important difference in regulatory treatment. SEC required minimum pricing increments constrain some stock spreads, causing large limit order queues. Dark pools allow some traders to by-pass...

We provide a cross-country test on three theoretical models that might explain the relation between trading volume and short-horizon price pattern that gives rise to contrarian/momentum profits. Based on weekly returns of seven Pacific-Basin countries, including Japan, Taiwan, Korea, Hong Kong,...

There have been a number of investigations of the individual characteristics of the limit order book (Lee, Mucklow, and Ready, 1993; Harris, 1994; Bruno, Hillion, and Spatt, 1995). Lee,Mucklow, and Ready report that wide spreads are accompanied by low depths and that spreads widen and depths fall in...

Microstructure research has recently forged two theoretical frameworks characterizing stock specialist behavior: a Walrasian inventory-theoretic individual optimization model sometimes with asymmetric information, and a queue-theoretic disequilibrium market model of the continuous auction...
