Liquidity traps and expectation dynamics: Fiscal stimulus or fiscal austerity?

Abstract: We examine global dynamics under infinite-horizon learning in New Keynesian models where the interest-rate rule is subject to the zero lower bound. The intended steady state is locally but not globally stable. Unstable deflationary paths emerge after large pessimistic shocks to expectations. For large expectation shocks that push interest rates to the zero bound, a temporary fiscal stimulus, or in some cases a policy of fiscal austerity, will insulate the economy from deflation traps if the policy is appropriately tailored in magnitude and duration. A fiscal stimulus “switching rule,” which automatically kicks in without discretionary fine-tuning, can be equally effective.
