摘要:This paper quantifies the analyst-firm relations based on an informational characteristic-model of analyst coverage innovatively. Furtherly, the rationality of analyst-firm relations is investigated based on the reciprocity between analysts and target firms by examining the impact of analyst-firm relations on stock recommendation and analysts’ earnings forecasting performance. Empirical results suggest that analysts are prompted by close analyst-firm relations to render relatively positive rating for target firms and reciprocated by more firm-specific information for better earnings forecasting performance.
