Abstract

For incomplete financial markets jumps in both prices and consumption can be unavoidable. We consider pure-exchange economies with infinite horizon, discrete time, uncertainty with a continuum of possible shocks at every date. The evolution of shocks follows a Markov process and fundamentals depend continuously on shocks. It is shown: (1) equilibria exist; (2) for effectively complete financial markets asset prices depend continuously on shocks; and, (3) for incomplete financial markets there is an open set of economies U such that for every equilibrium of every economy in U, asset prices at every date depend discontinuously on the shock at that date.
