Oxford University Press

An evaluation is made of potential ways in which product market competition can be operationalized as part of a panel data econometric analysis. As with corporate governance, it is necessary to identify suitable proxy variables. The OECD's NMR index is chosen as the most plausible measure of product market competition, an assessment reflected in its widespread utilization in the empirical economics literature.

Keywords:   product market competition, economic rents, proxy variables, NMR index
