This paper calls into question the currently most influential model of international trade. An empirical finding by Trefler (2004, AER) and others that industrial productivity increases more strongly in liberalized industries than in non-liberalized industries has been widely accepted as...

China’s policy-makers argued that WTO accession and the accompanying trade liberalization would have a beneficial impact on the domestic economy. China’s import tariffs differed tremendously across industry in the earlier years, but converged to an almost uniform low level after WTO entry....

Advocates of antidumping (AD) laws downplay their effects by arguing that the trade flows that are subject to AD are small and their distortions negligible.This paper is the first to counter that notion by quantifying the worldwide effect of AD laws on aggregate trade flows.The recent...

When in 1923 Jacob Viner wrote the book "Dumping: A Problem in International Trade", he probably did not imagine that the system put in place to eliminate the effects of dumping (i.e. antidumping) would surge to be a problem.However, as we celebrate the 100th anniversary of the first antidumping...

Some supporters of antidumping have argued that this procedure serves as a kind of "safety valve" for protectionist pressure.This paper examines whether there is any empirical evidence that the use of antidumping actions has contributed to tariff reductions in a sample of 35 developing and...

Abstract This paper develops a theoretical framework where a multinational firm (MNE) is allowed to acquire or sell a productive asset in multiple segmented asset markets. The asset is used to produce a final good which can be sold in multiple countries, with segmented product markets,...

This paper studies how simultaneously liberalizing trade and tightening environmental policy affect welfare in a second-best world. We consider a three-good two-factor small open economy. We allow for non-tradables and for market power in the export market. The government is constrained to...

This paper introduces optimal competition: the best form of competition in an industry that a competition authority can achieve under the information constraint that it cannot observe firms' effciency levels.We show that the optimal competition outcome in an industry becomes more competitive as...

This paper extends the firm heterogeneity model of Melitz (2003) by introducing a new concept of endegenous investments in process R&D. The novelty is that if a firm invests more R&D its expected innovation return hazard rate stochastically dominates the return of less R&D investments. Due to...

This paper shows that electoral incentives deter politicians from supporting trade liberalization. We focus on all major trade liberalization bills introduced since the early 1970s in the U.S. Congress, in which House and Senate members serve respectively two- and six-year terms and one third of...
