A rationalist explanation of Russian risk-taking

Three seemingly unrelated topics of Russian politics are investigated. It is shown that under expected utility maximization the assumptions of an unbiased oil forward market and a risk-acceptant attitude (strictly convex utility function) are sufficient to explain Russia’s open position in oil and the bailout of Rosneft. The risk-acceptant attitude of the Russian leader also causes a shrunken bargaining range for the conflict in Ukraine, which can be enlarged by sanctions but not necessarily by the proliferation of weapons. This gives sanctions a clear edge over the proliferation of weapons.
