This paper examines the effect of international trade on corporate market power in emerging market economies and developing countries, with a special focus on sub-Saharan Africa. The analysis is based on a large firm-level dataset, tariff data by sector and aggregate indicators of international...

There is not one, perfect model for institutional regulatory cooperation, nor is there a single model for eliminating technical barriers to trade or discriminatory sanitary and phytosanitary measures in a preferential trade agreement (PTA). However, recent experience with PTAs has shown that it...

Much potential for trade liberalization exists in industries and markets with trade barriers that are prohibitive for all or many firms. In standard political economic theories of trade policy, observed prohibitive barriers must be globally optimal according to static government preferences,...

Gravity equations have been used for more than 50 years to estimate ex post the partial effects of trade costs on international trade flows, and the well-known - and traditionally presumed exogenous - "trade-cost elasticity" plays a central role in computing general equilibrium trade-flow and...

We nest an extended two-way fixed effect (ETWFE) estimator for staggered difference-in-differences within the structural gravity model. To test the ETWFE, we estimate the effects of regional trade agreements (RTAs). The results suggest that RTA estimates in the current gravity literature may be...

The real effective exchange rate (REER) is one of the most cited statistical constructs in open-economy macroeconomics. We show that the models used to compute these numbers are not rich enough to allow for the rising importance of global value chains. Moreover, because different sectors within...
