We examine whether a shock to the enforceability of Regulation Fair Disclosure (Reg FD) limited its ability to restrict the flow of private information between managers and investors. Prior work provides evidence that Reg FD reduced managers' selective disclosure of material information...

We use the 2016 U.S. SEC tick size pilot to examine the effects of an increase in the minimum price variation on limit order book liquidity in NASDAQ-listed stocks on the NASDAQ exchange. For treatment stocks with an average pre-pilot quoted spread less than $0.05, the tick size increase is...
