Title: Supply Network Formation and Fragility
Title: Supply Network Formation and Fragility
Abstract: We model the production of complex goods in a large supply network. Each firm sources several essential inputs through relationships with other firms. Individual supply relationships are at risk of idiosyncratic failure, which threatens to disrupt production. To protect against this, firms multisource inputs and strategically invest to make relationships stronger, trading off the cost of investment against the benefits of increased robustness. We find that equilibrium aggregate production is robust to idiosyncratic disruptions. Nevertheless, there is a regime in which arbitrarily small systemic shocks cause arbitrarily steep drops in output, so that the the supply network is fragile. The endogenous configuration of supply networks provides a new channel for the powerful amplification of shocks.
This is joint work with Matthew Elliott and Matthew Leduc.

We collaborate with the INFORMS Auctions and Market Design online seminar series. This might be a particularly interesting seminar for those of you interested in the design of auctions, markets, and related questions in game theory and optimization. Please note that both seminars take place on Fridays, but on alternating weeks.
