This article offers a comparative analysis of the inflationary exeriences of Weimar Germany and post-Soviet Russia, applying theories about money and government budget constraints in the manner of Thomas Sargent and François Velde. The comparison looks beyond economic policy itself to the political and social consequences of the two inflationary crises. The parallel is fairly close: close enough to suggest that Russia, despite its recent quiescence, may not have seen the end of its monetary—or political—travails.
