Antidumping and Feed-In Tariffs as Good Buddies? Modeling the EU-China Solar Panel Dispute.

The paper analyzes the interactions between trade and renewable energy policies based on the EU-China solar panel dispute which is the most significant antidumping (AD) complaint in Europe. We build a price competition duopoly model with differentiated products and intra-industry trade in photovoltaic (PV) equipment. We show that an optimal antidumping duty always increases with the feed-in tariff (FIT) program set in the home country. An appropriate antidumping duty--nullifying the dumping margin--decreases with the FIT program. We show that optimal FIT increases with the AD duty. Therefore, trade and renewable energy optimal policies may complement one another. Lastly, we introduce R&D activities in the PV sector, and international spillovers. We show that R&D makes the optimal FIT lower and increases the dumping margin. These effects are reinforced by technological spillovers. [ABSTRACT FROM AUTHOR]
