Hausmann, R., Schetter, U. & Yildirim, M.A., 2022. On the Design of Effective Sanctions: The Case of Bans on Exports to Russia.Abstract
We analyze the effects of bans on exports at the level of 5,000 products and show how our results can inform economic sanctions against Russia after its invasion of Ukraine. We begin with characterizing export restrictions imposed by the EU and the US until mid May 2022. We then propose a theoretically-grounded criterion for targeting export bans at the 6-digit HS level. Our results show that the cost to Russia are highly convex in the market share of the sanctioning parties, i.e., there are large benefits from coordinating export bans among a broad coalition of countries. Applying our results to Russia, we find that sanctions imposed by the EU and the US are not systematically related to our arguments once we condition on Russia’s total imports of a product from participating countries. Quantitative evaluations of the export bans show (i) that they are very effective with the welfare loss typically ∼100 times larger for Russia than for the sanctioners. (ii) Improved coordination of the sanctions and targeting sanctions based on our criterion allows to increase the costs to Russia by about 60% with little to no extra cost to the sanctioners. (iii) There is scope for increasing the cost to Russia further by expanding the set of sanctioned products.
Hausmann, R., et al., 2022. Cutting Putin’s Energy Rent: ‘Smart Sanctioning’ Russian Oil and Gas.Abstract

Following the Russian aggression against Ukraine, major sanctions have been imposed by Western countries, most notably with the aim of limiting Russia’s access to hard international currency. However, Russia remains the world’s first exporter of oil and gas, and at current energy prices this provides large hard currency revenues. As the war continues, European governments are under increased pressure to scale-up their energy sanctions, following measures taken by the United States, the United Kingdom, Canada and Australia. This piece argues that given the inelasticity of Russia’s oil and gas supply, for Europe the most efficient way to sanction Russian energy would not be an embargo, but the introduction of an import tariff that can be used flexibly to control the degree of economic pressure on Russia.
