Preferential Trade Agreements andMulti-Product Firms Stefan Rouenhoff & Carsten Eckel University of Bamberg 11th Annual Conference of the European Trade Study Group Rome, September 10, 2009
Literature Preferential trade agreements and FDI • Horizontal FDI as tariff jumping motive and the intention to exploit the proximity to larger regional markets • E.g., Motta & Norman (1996), Puga & Venables (1997) Multi-product firms • High importance of multi-product firms (MPFs) • Horizontal FDI causes multiple way trade in differentiated final products • “Cannibalization” of own sales • E.g., Baldwin & Ottaviano (2001), Eckel & Neary (2009)
Theoretical Framework • Partial equilibrium analysis • One monopolistic MPF, located in a third country (C) • wants to supply two identical countries (j=A,B) • produces two product varieties (i=1,2), which aresubstitutable, 0<b<1 • Each variety is produced in a separate production plant under constant variable costs c • Each production plant is associated with fixed costs F • Unit tariff costs t are identical between all three countries
Theoretical Framework Comparison of two economic settings No preferential trade agreement between country A & B(non-integrated markets (NIM)) A preferential trade agreement between country A & B(integrated markets (IM)) No tariff costs between country A & B

Comparative Static Analysis Investment location
Comparative Static Analysis Welfare (Extension I: transportation costs ) , if , if
Results and Outlook • Relocation of production possible • Both, “tariff jumping motive” and “cannibalization reduction motive” are decisive for market supply stragegy • Welfare decrease possible • Extension II: varying country size • Extension III: varying tariff costs
