Testing the Link Between Multinationality and the Return on Foreign Assets

A large and robust empirical literature demonstrates that there is a strong relationship between the performance of a multinational enterprise (MNE) and its degree of multinationality We develop a new metric to capture the return on foreign assets (ROFA), which we use as an alternative metric to return on total assets (ROTA) as a dependent variable representing performance. We find a significant S-shaped relation between ROFA and the degree of multinationality across a large set of UK firms. [ABSTRACT FROM AUTHOR]
