This paper investigates whether accounting standards harmonization enhances the comparability of financial information across countries. I hypothesize that a firm yet to announce earnings reacts more strongly to the earnings announcement of a foreign firm when both report under the same rather than different accounting standards. My analysis of abnormal price reactions for a global sample of firms supports the prediction. Next, in an attempt to control for the underlying economic comparability and the effects of changes in reporting quality, I use a difference‐in‐differences design around the mandatory introduction of International Financial Reporting Standards. I find that mandatory adopters experience a significant increase in market reactions to the release of earnings by voluntary adopters compared to the period preceding mandatory adoption. This increase is not observed for nonadopters. Taken together, the results show that accounting standards harmonization facilitates transnational information transfer and suggest financial statement comparability as a direct mechanism.

We examine changes in firms’ dividend payouts following an exogenous shock to the information asymmetry problem between managers and investors. Agency theories predict a decrease in dividend payments to the extent that improved public information lowers managers’ need to convey their commitment to avoid overinvestment via costly dividend payouts. Conversely, dividends could increase if minority investors are in a better position to extract cash dividends. We test these predictions by analyzing the dividend payment behavior of a global sample of firms around the mandatory adoption of IFRS and the initial enforcement of new insider trading laws. Both events serve as proxies for a general improvement of the information environment and, hence, the corporate governance structure in the economy. We find that, following the two events, firms are less likely to pay (increase) dividends, but more likely to cut (stop) such payments. The changes occur around the time of the informational shock, and only in countries and for firms subject to the regulatory change. They are more pronounced when the inherent agency issues or the informational shocks are stronger. We further find that the information content of dividends decreases after the events. The results highlight the importance of the agency costs of free cash flows (and changes therein) for shaping firms’ payout policies.
