Search frictions, real rigidities and inflation dynamics

  • Carlos Thomas


    (Banco de España)

I analyze the effect of search frictions on inflation dynamics, in a New Keynesian model where firms make both pricing and vacancy posting decisions. I find that search frictions create real rigidities in price setting. This mechanism flattens the New Keynesian Phillips curve, relative both to the standard model with a frictionless labor market and a model where pricing and vacancy posting decisions are made by different subsets of firms. This helps the model improve its empirical performance along a number of dimensions. First, inflation becomes more persistent. Second, output responses to monetary shocks become larger and more persistent. Finally, unemployment becomes more volatile.
