Abstract

We study how trade policy affects firms’ ownership structures. We embed an incomplete contracts model of vertical integration choices into a standard perfectly-competitive international trade framework. Integration decisions are driven by a trade-off between the pecuniary benefits of coordinating production decisions and the managers’ private benefits of operating in preferred ways. The price of output is a crucial determinant of this choice, since it affects the size of the pecuniary benefits: higher prices lead to more integration. Because tariffs increase domestic product prices, this effect provides a novel theoretical channel through which trade policy can influence firm boundaries. We then examine the evidence, using a unique dataset to construct firm-level indexes of vertical integration for a large set of countries. In line with the predictions of our model, we obtain three main results. First, higher tariffs lead to higher levels of vertical integration. Second, differences in ownership structure across countries, measured by the difference in sectoral vertical integration indexes, are smaller in sectors with similar levels of protection. Finally, ownership structures are more alike among members of regional trade agreements.
