This paper introduces a bi-objective winner determination problem which arises in the procurement oftransportation contracts via combinatorial auctions. The problem is modelled as an extension to the setcovering problem and considers the minimisation of the total procurement costs and the...

We model the production of complex goods in a large supply network. Each firmsources several essential inputs through … idiosyncraticdisruptions. However, there is a regime in which equilibrium supply networks are fragile, withsmall aggregate shocks to … relationships causing arbitrarily steep drops in output. The endogenousconfiguration of supply networks provides a new channel for …
