Public Firm Presence, Financial Reporting, and the Decline of U.S. Manufacturing
研究发现上市公司存在与进口竞争正相关，外国竞争者可能利用上市公司财务报告中的信息来与国内企业竞争，从而加剧了美国制造业的衰退。
ABSTRACT We examine the relation between public firm presence and import competition. The information created by public firm presence may provide importers with insights they can use for competing with domestic firms. Consistent with this possibility, we document a positive relation between public firm presence and import competition. We find similar results when using differences in the expected costs of the Sarbanes‐Oxley Act as a source of plausibly exogenous variation in public firm presence after the act. We use differences in the proportion of German firms reporting publicly around a major enforcement reform as a natural mechanism experiment, and find evidence that financial reporting is a channel through which public firm presence relates to import competition. Additional mechanism tests and a falsification test estimated in the United Kingdom, where public and most private firms report publicly, further support this inference. In total, our evidence is consistent with foreign competitors using the information created by public firm presence, including what public firms disclose in financial reports, to compete with domestic firms. Consequently, our results provide evidence of competitors using the proprietary information disclosed in financial reports to compete with the disclosing firms and of information frictions affecting trade.
