We examine whether analysts’ prior industry experience influences their ability to serve as effective external firm monitors. Our analyses of firms’ financial disclosure quality, executive compensation and CEO turnover decisions portray a consistent picture that related pre-analyst industry experience is of critical importance for analysts to play an effective monitoring role. Coverage by analysts with such experience is associated with reduced earnings management, lower probability of committing financial misrepresentation, less CEO excess compensation, and higher performance sensitivity of CEO turnover. We also provide evidence on several plausible mechanisms through which industry expert analysts exert monitoring efforts and limit managerial opportunism.

Using hand‐collected biographical information on financial analysts from 1983 to 2011, we find that analysts making forecasts on firms in industries related to their preanalyst experience have better forecast accuracy, evoke stronger market reactions to earning revisions, and are more likely to be named Institutional Investor all‐stars. Plausibly exogenous losses of analysts with related industry experience have real financial market implications—changes in firms’ information asymmetry and price reactions are significantly larger than those of other analysts. Overall, industry expertise acquired from preanalyst work experience is valuable to analysts, consistent with the emphasis placed on their industry knowledge by institutional investors.
