Internationalization and Performance: Traditional Measures and Their Decomposition

Previous empirical results on the relationship between internationalization and firm performance have been mixed. Both monotonic and curvilinear relationships have been reported. Most recent studies have focused on different types of curvilinear relationships, such as inverted Ushaped, standard U‐shaped, and multiple waves. This paper utilizes a more current sample of firms than prior studies have used and decomposes traditional financial performance measures, applying two different measures of degree of internationalization, country scope and foreign sales as a percent of total sales (FSTS), to measure the effects on financial performance of different degrees of internationalization. Several financial performance measures, including traditional indexes (ROE and ROA) and a decomposition of traditional ones (Profit Margin, Total Asset Turnover), are examined.
