3 Exporter Characteristics and Dynamics Exporter characteristics Only 2% of US manufacturing plants exported in 992. (Bernard, Eaton, Jensen & Kortum 23) 2-8% more productive, 48% higher capital/worker, 2-45% more employment than non-exporters (Bernard & Jensen 999) Significant export costs 7-7% of a shipment s value (Alessandria et al. 2) Time-varying extensive margin of trade figure Entry rate = 3.9%, exit rate = 2.6% (Bernard & Jensen 24) Incomplete exchange rate pass-through 23% in short run, 42% in long run (Campa & Goldberg 25) Yuko Imura (Bank of Canada) Endogenous Trade Participation June 23 / 9

4 Objective This paper studies implications of endogenous trade participation for international business cycles, dynamics of trade participation, and exchange rate pass-through in an environment with nominal rigidities. Yuko Imura (Bank of Canada) Endogenous Trade Participation June 23 2 / 9

5 Main Findings With price rigidities, limited adjustments along intensive margin of trade lead to procyclical movements in the number of exporters, resulting in larger responses of export price and trade balance, in contrast to existing studies under flexible prices. Quantitative effect of extensive margin of trade on exchange rate pass-through is negligible, preserving incomplete pass-through in the presence of nominal rigidity. Entry and exit lead relatively more productive firms to dominate the export market. The model explains delayed response of trade balance and terms of trade to currency depreciation, with substantial adjustments along intensive and extensive margins.

10 Model Overview All intermediate-good producers sell in their own country. y t (i) = z t (i)a t K t (i) ν L t (i) ν z t (i) = current firm-specific productivity A t = aggregate productivity To enter the export market, a firm pays entry cost, η G E (η). Upon entering the export market, an entrant sets a new price for its exports. To continue exporting, a firm pays a continuation cost, ξ G(ξ).

27 Conclusion In the presence of price rigidity, endogenous trade participation influences international business cycles, in contrast to earlier findings under flexible prices. This suggests that market structure and pricing conventions may be critical in analyzing the role of exporter entry and exit for aggregate dynamics and international transmission of shocks. Endogenous trade participation and incomplete exchange rate pass-through have important implications for the effects of currency movements and the conduct of monetary policy at both micro and macro levels.
