Security Analysis, Agency Costs, and UK Firm Characteristics AbstractThe purpose of this paper is to assess the monitoring power of security analysts from the manager-shareholder conflict perspective. Using a net sample of 1,027 UK firms tracked by security analysts over the 1998-2000 period, our evidence supports the view that security analysis acts as a monitoring mechanism in reducing agency costs. More importantly, we also find that security analysts are more effective in reducing managerial non-value maximising behaviour for smaller and more focused firms rather than larger and more diversified firms supporting the supposition that as firms grow larger and more complex, the monitoring activity of security analysis becomes less effective with firm size. In addition, the evidence points out that security analysis has a positive and significant impact on firm value for smaller firms as opposed to larger ones. Overall, the UK findings suggest that the monitoring role of security analysts is not restricted to the U.S. capital market environment.
