Abstract:
Trade credit in the form of a delay of inputs payments is an important source of financing for all types of firms. In this paper, I study the role of credit linkages for the propagation of financial shocks in a production network where firms finance their working capital requirements using bank and trade credit. To this end, I build a quantitative multisector model with endogenous credit linkages between representative firms in each sector. The endogenous adjustment in the volume and cost of trade credit captures two counteracting mechanisms: (1) Firms smooth interest rate shocks by substituting bank and supplier finance. (2) An increase in the interest rate that a firm charges on trade credit tightens the financing terms of its customers thereby amplifying financial shocks. Quantitatively, the model accounts for 30% of the variation in aggregate output in the US-economy. Model simulations show that the existence of the trade credit network doubled the drop in aggregate output during the 2008-2009 crisis relative to an equivalent economy with bank-finance only. Furthermore, the ratio of total outstanding payments owed by customers for already delivered goods and services to bank credit is a good proxy for the systemic importance of a sector in propagating liquidity shocks.
