Agent-based macroeconomics for the UK's Seventh Carbon Budget
Tom Youngman, Tim Lennox, M. Lopes Alves +9
In June 2026, the UK government will set its carbon budget for the period 2038 to 2042, the seventh such carbon budget (CB7) since the Climate Change Act became law in 2008. For th…
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…
Revisiting Granular Models of Firm Growth
José Moran, Angelo Secchi, Jean-Philippe Bouchaud
We revisit granular models that represent the size of a firm as the sum of the sizes of multiple constituents or sub-units. Originally developed to address the unexpectedly slow re…
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…
Revealing production networks from firm growth dynamics
Luca Mungo, José Moran
We study the correlation structure of firm growth rates. We show that most firms are correlated because of their exposure to a common factor but that firms linked through the suppl…
Exact time-dependent dynamics of discrete binary choice models
James Holehouse, José Moran
We provide a generic method to find full dynamical solutions to binary decision models with interactions. In these models, agents follow a stochastic evolution where they must choo…
Out-of-Equilibrium Dynamics and Excess Volatility in Firm Networks
Théo Dessertaine, José Moran, Michael Benzaquen +1
We study the conditions under which input-output networks can dynamically attain a competitive equilibrium, where markets clear and profits are zero. We endow a classical firm netw…
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…
By Force of Habit: Self-Trapping in a Dynamical Utility Landscape
José Moran, Antoine Fosset, Davide Luzzati +2
Historically, rational choice theory has focused on the utility maximization principle to describe how individuals make choices. In reality, there is a computational cost related t…
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…
Greedy algorithms and Zipf laws
José Moran, Jean-Philippe Bouchaud
We consider a simple model of firm/city/etc. growth based on a multi-item criterion: whenever entity B fares better that entity A on a subset of items out of , the agent ori…
