报告简介：
Using hand-collected data on analysts’ activities on WeChat, we investigate how career concerns affect analysts’ effort allocation and their outcomes. We find analysts tend to write more tweets with more colorful expressions, promotion photos, and the number of words, chase hot stocks more timely, and leak more contents of research reports when approaching next Star contest voting period. The efforts on writing tweets significantly helps analysts’ career advancement, while conventional efforts like making more and better forecasts is useless. Instrumented by the number of months since last Star tournament, we find more effort on writing tweets leads to bolder but less accurate and informative earnings forecast and recommendations. Furthermore, distraction from tweets deteriorates firms’ information environment. Taking advantage of an exogenous shock which had led to the suspension of Star tournament, we find similar results using difference-in-differences analyses.
