Ludwig Straub, Harvard
Department seminar. Ludwig Straub is a post-doctoral fellow in economics at Harvard. He will present a paper entitled "Investment, heterogeneity, inattention".
We estimate a Heterogeneous-Agent New Keynesian model that matches existing microeconomic evidence on marginal propensities to consume and macroeconomic evidence on the impulse response to a monetary policy shock. We rule out habit formation as an explanation for the hump shape of output, but show that sticky information in the sense of Mankiw and Reis (2002) can rationalize both the micro and the macro data. Our estimated model implies a central role for investment in the monetary transmission mechanism.
