Preferential Trade Agreements and Multi-Product Firms
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)

Preferential Trade Agreements and Multi-Product Firms
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 are
substitutable, 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
Stefan Rouenhoff & Carsten Eckel, University of Bamberg
Preferential Trade Agreements and Multi-Product Firms
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

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
