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…
