Why We Should Stop Using the Kogut and Singh Index
指出国际商务研究中广泛使用的科古特和辛格文化距离指数存在错误，实际测量的是平方文化距离，导致实证结果可能误导，并给出基于欧氏距离的正确形式。
The Kogut and Singh (J Int Bus Stud 19(3):411–432, 1988) index is the most widely used construct to measure cultural distance in international business and management research. We show that this index is incorrectly specified and captures the squared cultural distance. This inaccuracy is problematic because it means that the empirical findings on the effects of cultural distance presented in different strands of international business research are likely to be misleading. We specify the correct form of the distance measure based on the Euclidean distance formula and demonstrate the implications of using the incorrectly specified Kogut and Singh (1988) index.
