We conduct an exploratory analysis of how researchers can address the issue of “construct validity”, which poses a major challenge to all studies of the effect of corporate governance on firm performance. Many corporate governance studies rely on aggregate governance “indices” to measure underlying, unobserved governance. But we are not confident that we know how to build these indices – often we are unsure both as to what is “good” governance, and how one can proxy for this vague concept using observable measures. These are construct validity questions.
