During the U.S.-China trade war, the U.S. punitive tariffs were almost entirely borne by U.S. importers. In contrast, only 68% of China's retaliatory tariffs were paid by Chinese importers. The puzzling difference between the U.S. and China is mainly driven by their different import structures...

Estimates of the trade elasticity based on actual trade policy changes are scarce, and the few that exist are all over the place. This paper offers a setting where an exogenous increase in a border tax can be used to estimate the trade elasticity. It shows theoretically and empirically that if...

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. Specifically, we argue that structural gravity estimations should be performed with data that include not only...

Blockchains, the technology underlying cryptocurrencies, face large fluctuations in user demand and marginal costs. These fluctuations make effective fee policies necessary to manage transaction service allocation. This paper models the conflict between the blockchain designer and validators...

How do trade costs affect international trade? This paper offers a new approach. We rely on a flexible gravity equation that predicts variable trade cost elasticities, both across and within country pairs. We apply this framework to the effect of currency unions on international trade. While we...

This paper points to the important role which the elasticity of aggregate capital supply with respect to the net rate of return to capital plays for the efficiency of policymaking in a decentralized economy with mobile capital and spillovers among jurisdictions. In accordance with previous...

Under standard assumptions, optimum commodity taxation (OCT) should target non-renewable resources (NRRs) in priority. NRRs should be taxed at a higher rate than otherwise-identical conventional commodities. NRR substitutes and complements should receive a particular tax treatment. When reserves...
