Price Dynamics, financial fragility and aggregate volatility

Abstract : Within a standard framework à la Arrow-Debreu, we investigate the dynamics emerging from the interactions of heterogeneous households and firms that are adaptive price setters and financially constrained. We show that depending on the stringency of the financial constraints the model can settle in two very different regimes: one characterized by equilibrium, the other by disequilibrium and financial fragility. We then investigate how the structure of the production network affects the emergence of aggregate volatility from micro-level price and financial shocks, hence providing a dynamical counterpart to recent results of Acemoglu and al (2012).
