Can directors impact performance? A case-based test of three theories of corporate governance

We examine hypothesised links between the board of directors and firm performance as predicted by the three predominant theories in corporate governance research, namely agency theory, stewardship theory and resource dependence theory. By employing a pattern matching analysis of seven cases, we are able to examine the hypothesised link between board demography and firm performance expected under each theory. We find that while each theory can explain a particular case, no single theory explains the general pattern of results. We conclude by endorsing recent calls for a more process-orientated approach to both theory and empirical analysis, if we are to understand how boards add value
