Query: The Transition from Brownian Motion to Boom-and-Bust Dynamics in
  Financial and Economic Systems   Quasi-equilibrium models for aggregate variables are widely-used throughout
finance and economics. The validity of such models depends crucially upon
assuming that the systems' participants behave both independently and in a
Markovian fashion.
  We present a simplified market model to demonstrate that herding effects
between agents can cause a transition to boom-and-bust dynamics at realistic
parameter values. The model can also be viewed as a novel stochastic particle
system with switching and reinjection.
