We examine how language barriers affect the capital market reaction to information disclosures. Using transcripts from non-U.S. firms' English-language conference calls, we find that the calls of firms in countries with greater language barriers are more likely to contain non-plain English and erroneous expressions. For non-U.S. firms that hire an English-speaking manager, we find less use of non-plain English and fewer erroneous expressions. Calls with a greater use of non-plain English and more erroneous expressions show lower intraday price movement and trading volume. The capital market responses to non-plain English and erroneous expressions are more negative when the firm is located in a non-English-speaking country and has more English-speaking analysts participating in the call. Our results highlight that, when disclosure happens verbally, language barriers between speakers and listeners affect its transparency, which, in turn, impacts the market's reaction.

We examine how managers' ethnic cultural background affects their communication with investors. Using earnings conference calls with executives from 42 countries, we find that managers from ethnic groups that have a more individualistic culture use a more optimistic tone and exhibit greater self-reference. Managers' ethnic culture has a lasting effect and persists for executives whose work experience later exposes them to different ethnic cultures. The effect of ethnic heritage is observed in dialogues that reflect real-time interactions (i.e., Q&A ) and is less pronounced in the scripted, less spontaneous portion of the calls (i.e., management discussion). Analysts respond positively to optimistic tone, but only those who share the manager's ethnic background adjust their earnings forecasts for the cultural component of managerial tone. The findings suggest that managers' ethnic background has a significant effect on how they communicate with the capital market and how the market responds to the disclosure.
