Vertical integration in the U.S. auto industry : A note on the influence of transaction specific assets

Abstract

Recent refinements in the theory of the firm suggest that organization form may be sensitive not only to the degree to which assets are specific to a transaction but also to the type of capital employed. This paper reports evidence regarding the relative influence of transaction-specific investments in physical and human capital on the pattern of vertical integration using new data obtained directly from U.S. auto manufacturers. The results support the proposition that investments in specialized technical know-how have a stronger influence than those in specialized physical capital on the decision to integrate production within the firm.
