Resilient-to-Fragile Transition and Excess Volatility in Supply Chain Networks
David Martin, José Moran, Debabrata Panja +1
We study a production network in which firms use non-substitutable (Leontief) inputs, hold precautionary inventories and face idiosyncratic productivity shocks, with adjustment occ…
A differentiable model of supply-chain shocks
Saad Hamid, José Moran, Luca Mungo +2
Modelling how shocks propagate in supply chains is an increasingly important challenge in economics. Its relevance has been highlighted in recent years by events such as Covid-19 a…
Timeliness criticality in complex systems
José Moran, Matthijs Romeijnders, Pierre Le Doussal +4
In complex systems, external parameters often determine the phase in which the system operates, i.e., its macroscopic behavior. For nearly a century, statistical physics has extens…
Critical fragility in socio-technical systems
José Moran, Frank P. Pijpers, Utz Weitzel +2
Socio-technical systems, where technological and human elements interact in a goal-oriented manner, provide important functional support to our societies. Here we draw attention to…
From Ants to Fishing Vessels: A Simple Model for Herding and Exploitation of Finite Resources
José Moran, Antoine Fosset, Alan Kirman +1
We analyse the dynamics of fishing vessels with different home ports in an area where these vessels, in choosing where to fish, are influenced by their own experience in the past a…
Schrödinger's ants: A continuous description of Kirman's recruitment model
José Moran, Antoine Fosset, Michael Benzaquen +1
We show how the approach to equilibrium in Kirman's ants model can be fully characterized in terms of the spectrum of a Schrödinger equation with a Pöschl-Teller () potenti…
May's Instability in Large Economies
José Moran, Jean-Philippe Bouchaud
Will a large economy be stable? Building on Robert May's original argument for large ecosystems, we conjecture that evolutionary and behavioural forces conspire to drive the econom…
