Inter-Firm Relationships and Asset Prices

Abstract

This paper proposes a novel link between the propagation of shocks within production networks and asset prices. It develops a dynamic network model in which the propagation of firm cash-flow shocks via inter-firm relationships affects the economy's equilibrium asset prices. When calibrated to match key features of customer-supplier networks in the United States, the model generates long-run risks, high and volatile risk premia, and a low and stable risk-free rate. Consistent with data from firms in manufacturing and service industries, the model predicts that central firms in the network command lower risk premiums than peripheral firms, and that firm-level return volatilities exhibit a high degree of co-movement.
