Global Sourcing and Credit Constraints

Abstract

This paper incorporates credit constraints into a model of global sourcing and heterogeneous firms. Following Antras and Helpman (2004), heterogeneous firms decide whether to outsource or integrate input suppliers. Financing of fixed organizational costs requires borrowing with credit constraints and collateral based on tangible assets. The party that controls intermediate inputs is responsible for these financing costs. Sectors differ in their reliance on external finance and countries vary in their financial development. The model predicts that increased financial development decreases the share of integration relative to outsourcing in a country. The effect is more pronounced in sectors with a high reliance on external finance. However, this effect is mitigated by higher productivity (TFP) and headquarter intensity. Empirical examination confirms the predictions of the model. An improvement in financial development from the 25th to the 75th percentile in industries at the 75th percentile in finance dependence relative to those at the 25th percentile is associated with a 16.8% decrease in the median share of U.S. intra-firm imports. An increase in TFP from the 25th to the 75th percentile in the TFP triple interactions increase the share of U.S. intra-firm imports at the median by 3.2%. An increase in headquarter intensity from the 25th to the 75th percentile in the headquarter intensity triple interactions increase the share of U.S. intra-firm imports at the median by 21%.
