ABSTRACT We investigate whether ineffective internal control over financial reporting has implications for firm operations by examining the association between inventory-related material weaknesses in internal control over financial reporting and firms' inventory management. We find that firms with inventory-related material weaknesses have systematically lower inventory turnover ratios and are more likely to report inventory impairments relative to firms with effective internal control over financial reporting. We also find that inventory turnover rates increase for firms that remediate material weaknesses related to inventory tracking. Remediating firms also experience increases in sales, gross profit, and operating cash flows. Finally, we assess the generalizability of our findings by examining all material weaknesses in internal control over financial reporting, regardless of type, and provide evidence that firms' returns on assets are associated with both their existence and remediation. Collectively, our findings support the general hypothesis that internal control over financial reporting has an economically significant effect on firm operations.

This paper evaluates the impact of three different performance incentive schemes using data from a social experiment that randomized 88 Mexican high schools with over 40,000 students into three treatment groups and a control group. Treatment 1 provides individual incentives for performance on curriculum-based mathematics tests to students only, treatment 2 to teachers only, and treatment 3 gives both individual and group incentives to students, teachers, and school administrators. Program impact estimates reveal the largest average effects for treatment 3, smaller impacts for treatment 1, and no impact for treatment 2.

This paper provides a systematic analysis of identification in linear social interactions models. This is a theoretical and econometric exercise as the analysis is linked to a rigorously delineated model of interdependent decisions. We develop an incomplete information game for individual choice under social influences that nests standard models as special cases. We consider identification of both endogenous and contextual social effects under alternative assumptions regarding an analyst’s a priori knowledge of social structure or access to individual-level or aggregate data. Finally, we discuss potential ramifications for identification of endogenous formation of social structure.
