We investigate the monitoring quality of accountants with ties to the Mafia in their role as auditors for “clean” firms—those with no known ties to organized crime. Using a proprietary government database, we identify Italian firms with alleged ties to the Mafia through their executives, directors, or shareholders. We define “suspect accountants” as those who serve as auditors for these Mafia‐connected firms, acknowledging their potential associations with criminal entities. We predict and find evidence that “clean” clients (treatment group) monitored by suspect accountants are more likely to engage in earnings management practices that reduce taxable income, compared with a control sample of “clean” firms monitored by accountants with no known Mafia ties (control group). Our findings suggest that accountants with ties to the Mafia act as low‐quality monitors in the “clean” economy.

This paper examines whether a country's corporate transparency environment, which includes the quality of accounting information, contributes to efficient resource allocation. Based on a cross‐country study of 37 manufacturing industries in 37 countries, we provide three pieces of related evidence. First, we find the contemporaneous correlations in industry growth rates across country pairs are higher when there is a greater level of corporate transparency in the country pairs, after controlling for country‐level economic and financial development. Second, we find the influence of transparency on these correlations is stronger when country pairs are at similar levels of economic development (GDP). Finally, when we control for the level of transparency explained by a country's institutions in place, we find that residual transparency (unexplained by country‐level factors) is associated with industry‐specific growth rates. Taken together, the results are consistent with corporate transparency facilitating the allocation of resources across industry sectors.
