摘要

Firms in a vertical relationship are likely to affect each other's productivity. Exactly how does productivity spill over across this type of relationship (i.e., through which mechanisms)? Additionally, how does the relative importance of these mechanisms depend on the structure of the supply chain? To answer these questions, we decompose the channels of upstream productivity spillovers-from customers to suppliers-by developing a structural econometric model on a sample of approximately 22,500 supply chain dyads. We find that the endogenous channel (i.e., the effect of the customer's own productivity on the supplier's productivity) is by far the most important source of spillovers. This is especially true if (i) the supplier has a concentrated customer base, (ii) the supplier and the customer have similar operational characteristics, and (iii) the relationship has medium maturity. In the converse scenarios, we find, it is more important to have a partner with a portfolio of favorable contextual characteristics (high inventory turnover, financial liquidity, and asset turnover) than to have a productive partner.
