Abstract:
Contractual frictions are widely known to shape firm boundaries. But do better contracting institutions, which reduce these frictions, induce firms to be more or less deeply integrated? This paper provides a large-scale investigation of this question using a unique micro dataset of ownership shares across half a million firm pairs worldwide. We uncover strong evidence that better contracting institutions in subsidiaries' countries favor deeper integration, particularly in relationship-specific industries. We formally show that these findings can be explained by a generalized Property-Rights Theory of the firm featuring partial ownership, while they are at odds with the canonical Transaction-Cost Theory.
