Is the interaction of international diversification and economic performance a linear relationship?
The current study analyses the effect of an international diversification strategy measured by multi-nationality and country scope, and tests its relationship with economic performance in the context of Australian corporate activity. Evidence from previous US studies on the relationship between international diversification strategy and economic performance was inconclusive, which suggests that research should go further with empirical analysis than testing for a linear relationship and should test for curvilinear relationships resulting from transactions costs analysis. Guided by that evidence a Chow test was used in the current study to establish a cut-off point that divided the sample of Australian firms into two subgroups (low-to-moderate and high level international diversification) to determine whether a non-linear relationship existed between economic performance and international diversification. This approach followed a similar technique used by Hitt, Hosskisson and Kim, (1997
