We introduce a version of the Cumulative Offer Algorithm of Hatfield and Milgrom(2005) modified for the supply chain networks setting of Ostrovsky (2008). The algorithmprovides an alternative proof for existence of a chain stable network. Moreover, we show that when choice functions satisfy...

In a general model of trading networks with bilateral contracts, we propose a suitably adapted chain stability concept that plays the same role as pairwise stability in two-sided settings. We show that chain stability is equivalent to stability if all agents' preferences are jointly fully...

We investigate whether network closure in the supply chain can explain the heterogeneity observed in import premia. Using unique panel data on trade flows among beef farms in the Italian region of Piedmont, we analyze a purely sequential supply chain characterized by the co-existence of two...

The restrictive measures that have been imposed from March 2020 on business activities in several countries to reduce the spread of the COVID-19 pandemic can be interpreted as shocks to global supply chains. We propose some agent-based models to evaluate the economic effects of different...

The question of how to optimally design an infrastructure network that may be subject to intelligent threats is of highest interest. We address this problem by considering a Designer-Adversary game of optimal network design for the case of imperfect node defense. In this two-stage game, first...

The Optimization principles are now considered center of Supply Chain Management (SCM) process. In this paper we will review conceptually the general approach of Optimization of Supply Chain Network for manufacturers. The mathematical modelling which are used for the designing Supply Chain...

Power is one of the key components in understanding and analyzing global production and is central to the analytical frameworks of both GVCs and GPNs. By focusing on firms' power within GPNs, we are able to draw a novel analytical link between the governance structures of GVCs and network...

We study production networks where firms' products can be described by a set of input and output characteristics, and links are formed only if the output characteristics of a seller match the input characteristics of a customer. We introduce a fully endogenous network formation model with...

We show that supply networks are inefficiently, and insufficiently, resilient. Upstream firms can expand their production capacity to hedge against supply and demand shocks. But the social benefits of such investments are not internalized due to market power and market incompleteness. Upstream...
