A large class of models with CES utility and iceberg trade costs are now known to generate isomorphic “gravity …” variable and the elasticity of trade with respect to true ad valorem “trade costs.” In this paper, we offer three potential … (σ), can be estimated precisely – even without observable true ad valorem trade-cost measures – using exporter …

We derive a simple equation for the welfare gains from trade when tariffs are liberalized or iceberg trade costs fall … countries with relatively high status quo tariffs, our formula predicts 30-60\% larger gains from trade than the icebergs only …. Covering various one-sector trade models that may or may not feature extensive margins and imperfect competition, we generalize …

Recent quantitative trade models treat import tariffs as pure cost shifters so that their effects are similar to … iceberg trade costs. We introduce revenue-generating import tariffs, which act as demand shifters, into the framework of … formula predicts 30-60% larger gains from trade when iceberg trade costs and/or tariffs are liberalized as compared to a pure …

Furthermore, in the two-country Nash equilibrium, tariffs turn out … to be strategic substitutes. Small or poor economies set lower Nash tariffs than large or rich ones. Lower transportation …

We propose a simple method to identify the effects of unilateral and non-discriminatory trade policies on bilateral … trade within a theoretically-consistent empirical gravity model. Specifi-cally, we argue that structural gravity estimations … should be performed with data that include not only international trade flows but also intra-national trade flows. The use of …

We quantify the economic impact of a potential secession of Catalonia from Spain. Using a novel dataset of trade flows … between 17 Spanish sub-national regions and 142 countries, we estimate effects of different levels of borders on trade flows … associated political uncertainty. In counterfactual experiments, we impose new borders on Catalan trade, potentially within or …
