This study investigates how accounting harmonization affects one particular group of financial statement users—financial analysts. We find that mandatory International Financial Reporting Standards (IFRS) adoption attracts foreign analysts, particularly those from countries that are simultaneously adopting IFRS along with the covered firm's country and those with prior IFRS experience. We also find that mandatory IFRS adoption improves foreign analysts’ forecast accuracy. The change in analyst following increases with the distance between prior local Generally Accepted Accounting Principles (GAAP) and IFRS and with the extent to which IFRS adoption eliminates GAAP differences between the firm's country and the analyst's country. IFRS adoption also attracts more local analysts, particularly those with prior IFRS experience and with an international portfolio prior to mandated IFRS adoption in their home country. Local analysts’ forecast accuracy is not affected by IFRS adoption. Overall, our results suggest that accounting harmonization brings comparability benefits that enhance the usefulness of accounting data.

Prior research demonstrates that a strong institutional infrastructure in a country moderates self‐serving behavior of market participants. Cross‐country economic activities have increased significantly, presenting a research opportunity to examine the relative influence of local versus foreign institutional infrastructure on individual market participants. We utilize variation in analyst‐country location relative to covered firm location to examine institutional determinants of optimism in analyst research. Focusing on target prices, where persistent optimism is well documented, we find that analysts domiciled in countries with stronger institutional infrastructures exhibit significantly attenuated target price optimism and more value‐relevant target prices. Our results demonstrate the importance of domestic country‐level institutional factors in moderating self‐serving behavior of market participants engaged in cross‐country activities.
