Abstract

This paper reformulates the New Keynesian model to incorporate output adjustments through the extensive margin. Shifting from adjustments through the intensive to the extensive employment margin, the model introduces predetermined output, altering key properties of the New Keynesian framework. First, the Taylor principle is inverted: stability is achieved when nominal rates respond less than one-for-one with inflation. Second, the model significantly alters the output responses to changes in monetary policy. We argue that this represents a challenge and an opportunity for the literature. Sticky information allows the model to correct the sign of impulse responses.
