This paper studies a recent tick size reduction in the U.S. Treasury securities market and identifies its effects on the market's liquidity and price efficiency. Employing difference-indifference regressions, we find that the bid-ask spread narrows significantly after the change, even for large...

Differences in market structures may affect the manner in which fundamental information is incorporated into prices. High levels of quote and trade transparency plus substantial quoting obligations in European government securities markets ensure that prices are informationally efficient. The...

We analyze different dimensions of liquidity on the Istanbul Stock Exchange (ISE) by using detailed order and transaction data for all ISE stocks. We estimate the limit order book on the ISE at each point in time and examine the intraday behavior of spreads, depths, returns and volume. We find...

This supplemental appendix extends the main paper by presenting additional analyses and robustness checks. It also describes the procedure to construct the Monthly TAQ effective spread benchmark.The paper "A Simple Estimation of Bid-Ask Spreads from Daily Close, High, and Low Prices" to which...

We propose a new method to estimate the bid-ask spread when quote data are not available. Compared to other low-frequency estimates, this method utilizes a wider information set, namely, readily available close, high, and low prices. In the absence of end-of-day quote data, this method generally...

Using data from the 2016-2018 tick size pilot study, we examine the efficacy of using wider tick sizes to subsidize market-making in small capitalization stocks. We demonstrate that realized spreads decay quickly within the initial microseconds of a trade. The effect reduces the subsidy offered...

Transaction costs in many international equity markets are reported as being much larger than those in the U.S. This raises questions such as what trade size these reported trading costs relate to and whether investors can reduce trading costs by timing their trades. We show, using data from the...
