Kyiv School of Economics invites to the academic seminar "Endogenous Production Networks and Non-Linear Monetary Transmission" by Mishel Ghassibe, University of Oxford/NBU. The seminar will be held in English online via Zoom. To get a link please register below.

Date&Time: Thursday, December 10, 17:00 (Kyiv time).

About the speaker. Mishel Ghassibe is a PhD Candidate at the Department of Economics, University of Oxford and a Chief Expert at the Research Unit of the Monetary Policy and Economic Analysis Department of the National Bank of Ukraine. His research interests are in macroeconomics, with a particular focus on the implications of firm heterogeneity and goods market frictions for macroeconomic policies.

Abstract. I develop a tractable sticky-price New Keynesian model, where input-output linkages across sectors are formed endogenously through firms' optimizing decisions. My model is able to jointly rationalize several of the empirically documented non-linearities associated with monetary transmission, which cannot be explained by workhorse models. First, the magnitude of real GDP's response to a monetary shock is procyclical in my model. This cycle dependence occurs because in expansions the level of productivity is high, encouraging firms to connect to more suppliers, which in turn facilitates stronger downstream propagation of price rigidity. Second, short-run non-neutrality of real GDP is higher following periods of loose monetary policy. The latter path dependence happens as under nominal rigidities, higher supply of money erodes the real prices charged by suppliers, encouraging more connections and hence a stronger contagion of stickiness to customer firms. Third, large monetary expansions make the production network denser, and hence have a disproportionally larger effect than small monetary expansions; on the other hand, large monetary contractions break the network and hence have a disproportionally smaller effect on GDP. The latter size dependence holds even under fully time-dependent pricing.
