We examine how interactions with foreign capital, product, and labor markets affect the disclosure practices of non-U.S. multinational firms. Drawing on literature related to multinationals, country-level legal institutions, and accounting disclosures, we expect that the relation between globalization and voluntary disclosure will be conditioned on the legal environment in a firm's home country. Specifically, while firms from strong legal environment countries (e.g., common law countries) already face pressure for good disclosure, globalization can increase the benefits associated with good disclosure for firms from weak legal environments (e.g., civil law countries). We use a self-constructed voluntary disclosure index and hand-collected disclosure and foreign activity data for 643 non-U.S. firms from 30 countries. We find a significant interaction between globalization and legal environment. This indicates that for the same level of globalization, there is more voluntary disclosure for firms based in weak legal environments. Our results suggest that globalization is an important variable that has been overlooked in much of the previous cross-country research.
