This paper studies price and quality differences across international intermediate input suppliers. We develop price measures that account for (i) differences in product characteristics, (ii) unobserved quality differences, and (iii) pure (frictional) price dispersion across suppliers. Using...

We study the cross-sectional dispersion of prices paid by EMU importers for French products. We document a significant level of price dispersion both within product categories across exporters, and within exporters across buyers. This latter source of price discrepancies, sellers' price...

Carbon control policies in OECD countries commonly differentiate emission prices in favor of energy-intensive industries. While leakage provides a efficiency argument for differential emission pricing, the latter may be a disguised beggar-thy-neighbor policy to exploit terms of trade. Using an...

This paper examines the welfare effects of intellectual property protection, accounting for firms' optimal responses to legal environments and technological innovation. I examine firms' use of indirect price discrimination in response to U.S. copyright law, which effectively prevents direct...

Regulators around the world are discussing, or taking action to limit, self-preferencing by large platforms. This paper explores Amazon's search rankings of its own products as the European Union's Digital Markets Act (DMA) was coming into effect. Using data on over 8 million Amazon search...

We introduce a new method for conditioning out serially correlated unobserved shocks to the production technology by building ideas first developed in Olley and Pakes (1996). Olley and Pakes show how to use investment to control for correlation between input levels and the unobserved...

This paper shows that the usual excess-burden triangle' formula performs poorly when used to assess the excess burden from taxes on intermediate inputs or consumer goods, and derives a practical alternative to this formula. We use an analytically tractable general equilibrium model to reveal how...

This paper examines the evidence on technology diffusion through trade in differentiated intermediate goods. Because intermediates are invented through costly research and development (R&D) investments, employing imported intermediates implies an implicit sharing of the technology that was...

This paper introduces an imported input into a model of art open economy with developed financial markets, a flexible exchange rate, and some degree of market power on the export side. The model is designed to investigate the impact of an increase in imported input prices on the exchange rate,...

My topic is the question: what difference does the set of commercial policies chosen by a developing country make to its rate of economic growth? Three points are salient. First, in its present state, trade theory provides little guidance as to the role of trade policy and trade strategy in...
