2 Questions: Are Financial Frictions Important as a Source of Shocks and/or Propagation in Aggregate Data?
3 Model Structure Base: closed economy model of CEE. Add: Financial Frictions as in BGG, CMR. Add: Labor Market Frictions as in MP, Gertler Trigari, CIMR. Add: Open Economy as in Adolfson, Laséen, Lindé and Villani (2005)

6 Need Additional Price Frictions in Export Sector Exports potentially defeat hump shape p response of output to a monetary shock. Recall: habit in consumption, investment adjustment costs limit rise in demand after monetary policy shock, and so limit rise in output in closed economy. In open economy, extra source of demand: exports. Expansionary MP shock depreciates exchange rate, S, stimulates foreign demand. To stop this, we suppose that exports have sticky prices, set in foreign currency units ( pricing to market )
