This study demonstrates that speed of change in the breadth of international markets has a positive but curvilinear effect on return on assets and has a negative but curvilinear effect on Tobin's Q. Meanwhile, speed of change in international commercial intensity has a positive but curvilinear effect on return on assets and no significant effect on Tobin's Q. Finally, speed of change in the commitment of foreign resources has a positive but curvilinear effect on both return on assets and Tobin's Q.
