The study argues that mandatory disclosure can reduce stock manipulation by increasing transparency, which in turn lowers excess stock volatility. Using a review of voluntary disclosure practices by NYSE firms before 1934, the authors compare groups and find larger post-Act volatility declines for firms with poorer disclosure. Liquidity improvements are also larger and link to the volatility reduction, supporting the legislators’ aim to curb excessive market volatility.","cbCaipGG7AT4uNlf","https://ap.wps.com/l/cbCaipGG7AT4uNlf","pdf",2201962,1,60,"English","en","# Abstract\n# Introduction\n## Mandatory disclosure, transparency, and information asymmetry\n## Deterrence, legal enforcement frictions, and limits of voluntary disclosure\n## Motivation for mandated disclosure","[{\"question\":\"What is the core research question of the paper?\",\"answer\":\"Whether the U.S. Securities Exchange Act of 1934 significantly stabilized the market through mandatory information disclosure.\"},{\"question\":\"How does mandatory disclosure affect stock volatility in the paper’s argument?\",\"answer\":\"Mandatory disclosure is argued to curb stock manipulation by improving transparency, thereby reducing excess stock volatility.\"},{\"question\":\"What empirical pattern do the authors find regarding firms with different disclosure quality?\",\"answer\":\"Firms with poorer disclosure practices experienced a significantly greater reduction in volatility after the 1934 Act than firms with better disclosure practices.\"}]",1780261257,151,{"code":4,"msg":28,"data":29},"ok",{"site_id":30,"language":22,"slug":31,"title":13,"keywords":32,"description":14,"schema_data":33,"social_meta":84,"head_meta":86,"extra_data":88,"updated_unix":25},105,"does-securities-regulation-matter-mandatory-disclosure-excess-stock-volatility-and-the-us-1934-securities-exchange-act","",{"@graph":34,"@context":83},[35,52,66],{"@type":36,"itemListElement":37},"BreadcrumbList",[38,42,46,49],{"item":39,"name":40,"@type":41,"position":19},"https://docshare.wps.com","Home","ListItem",{"item":43,"name":44,"@type":41,"position":45},"https://docshare.wps.com/document/","Document",2,{"item":47,"name":12,"@type":41,"position":48},"https://docshare.wps.com/document/research-report/",3,{"item":50,"name":13,"@type":41,"position":51},"https://docshare.wps.com/document/does-securities-regulation-matter-mandatory-disclosure-excess-stock-volatility-and-the-us-1934-securities-exchange-act/31821/",4,{"url":50,"name":13,"@type":53,"author":54,"headline":13,"publisher":56,"fileFormat":59,"description":14,"dateModified":60,"datePublished":60,"encodingFormat":59,"isAccessibleForFree":61,"interactionStatistic":62},"DigitalDocument",{"name":9,"@type":55},"Person",{"url":39,"name":57,"@type":58},"DocShare","Organization","application/pdf","2026-05-31",true,{"@type":63,"interactionType":64,"userInteractionCount":4},"InteractionCounter",{"@type":65},"ViewAction",{"@type":67,"mainEntity":68},"FAQPage",[69,75,79],{"name":70,"@type":71,"acceptedAnswer":72},"What is the core research question of the paper?","Question",{"text":73,"@type":74},"Whether the U.S. Securities Exchange Act of 1934 significantly stabilized the market through mandatory information disclosure.","Answer",{"name":76,"@type":71,"acceptedAnswer":77},"How does mandatory disclosure affect stock volatility in the paper’s argument?",{"text":78,"@type":74},"Mandatory disclosure is argued to curb stock manipulation by improving transparency, thereby reducing excess stock volatility.",{"name":80,"@type":71,"acceptedAnswer":81},"What empirical pattern do the authors find regarding firms with different disclosure quality?",{"text":82,"@type":74},"Firms with poorer disclosure practices experienced a significantly greater reduction in volatility after the 1934 Act than firms with better disclosure practices.","https://schema.org",{"og:url":50,"og:type":85,"og:title":13,"og:site_name":57,"og:description":14},"article",{"robots":87,"canonical":50},"index,follow",{"doc_id":7,"site_id":30}]
