ABSTRACT: This study examines the relation between internal controls and conditional conservatism (“conservatism”), also referred to as timely loss recognition. Using a sample of firms that disclose material weaknesses (MWs) in internal controls under the Sarbanes-Oxley Act (SOX), we find a positive relation between internal control quality and conservatism. Specifically, firms with MWs exhibit lower conservatism than firms without such weaknesses. Further, firms that disclose MWs and subsequently remediate these weaknesses exhibit greater conservatism than firms that continue to have MWs. Overall, these results are consistent with strong internal controls acting as a mechanism that facilitates conservatism. Our study contributes to the literature on the reporting effects of strong versus weak internal controls.

We examine stock exchange trading rules for market manipulation, insider trading, and broker–agency conflict, across countries and over time, in 42 stock exchanges around the world. Some stock exchanges have extremely detailed rules that explicitly prohibit specific manipulative practices, but others use less precise and broadly framed rules. We create new indices for market manipulation, insider trading, and broker–agency conflict based on the specific provisions in the trading rules of each stock exchange. We show that differences in exchange trading rules, over time and across markets, significantly affect liquidity.
