摘要：This paper compares the welfare implications of two widely used pricing assumptions in the New-Keynesian literature: Calvo-pricing vs. Rotemberg- pricing. We show that despite the strong similarities between the two assump- tions to a first order of approximation, in general they might entail different welfare costs at higher order of approximation. In the special case of non- distorted steady state, the two pricing assumptions imply identical welfare losses to a second order of approximation
