题目：Endogenous Production Networks and the Business Cycle
摘要：This paper develops a structural model of trade between heterogeneous firms in which the network of firm-level input-output linkages is endogenously determined. Firms vary in the size of their customer and supplier bases and adjust their sets of trade partners over time. Using data on buyer-seller relationships between US firms, I structurally estimate the model's key parameters, and apply the theory to quantify how important the endogenous adjustment of the production network is for US business cycles. Simulations of the model show that extensive margin adjustments of the production network over horizons of one year account for around 4% of observed real gross output and welfare, while adjustments over longer horizons account for larger components of these outcomes. Furthermore, adjustment of the production network is quantitatively important primarily as a response to idiosyncratic shocks at the relationship level rather than the firm level.
