Efficiency of Corporate International Diversification: Evidence from Developing Countries
During the last two decades corporate international diversification became a widely used growth strategy. However, the majority of scientific researches insist on its value-destroying pattern. Those of them which were based on accounting studies’ methodology and used current performance measures are likely to make an incomplete evaluation of corporate performance by accounting either for operating performance or financial (cost of capital) effects of internationalization. The current paper proposes a new approach for estimation of internalization-performance relationship which is based on economic profit concept. It allows to control simultaneously both operating and financial effects of internationalization on the firms’ current performance. The proposed model has been empirically tested on a sample of large companies from one of emerging economies - Russia. The results identify a non-linear U-shape relationship between a degree of internationalization and companies’ residual income (economic profit). The relationship is mainly determined by operating performance effects on economic profit while cost of capital has a modest effect. Overall for the majority of companies international diversification refers to decrease in economic profit. The results are compared against the Q-Tobin measure which incorporates expectations about future performance. A joint analysis of current performance (economic profit) and long-term performance (Q-Tobin) allows to expect the internationalization benefits to be realized in future. As an implication of the present research for corporate decision makers it may be stated that at the initial level of international diversification the internationalization decisions should be made with a high degree of caution. There should be a clear internationalization strategy based on definite mechanisms of performance improvement. The prestige and other irrational motives which may lead to the value destruction should be pruned.
