Multiple Reserve Requirements, Exchange Rates, Sudden Stops and Equilibrium Dynamics in a Small Open Economy

We model a typical Asian-crisis-economy using dynamic general equilibrium tech-niques. Exchange rates obtain from nontrivial fiat-currencies demands. Sudden stops/bank-panics are possible, and key for evaluating the merits of alternative ex-change rate regimes. Strategic complementarities contribute to the severe indetermi-nacy of the continuum of equilibria. The scope for existence and indeterminacy of equilibria and dynamic properties are associated with the underlying policy regime. Binding multiple reserve requirements promote stability under floating but increase the scope for panic equilibria under both regimes. Backing the money supply acts as a stabilizer only in fixed regimes, but reduces financial fragility under both regimes.
