The present article asks what lessons the empirical case of institutional change in post-Soviet Russia yields for the recent research on ideas and institutions. Its main point is that in post-Soviet Russia a clash between imported foreground ideas and deep domestic background ideas led to an ideational division among the elite of the country that became a main obstacle to the provision of coherent economic reforms. This story stands in some contrast to much of the newer literature on ideas and (...) institutions, which tends to see critical junctures as leading from one equilibrium to another. I argue that tensions between imported foreground ideas and deep domestic backgrounds are likely to occur in other cases of far-reaching processes of institutional change based on Western ideas but taking place beyond the realm of Western, industrialized countries. Therefore, I argue, some general lessons on the interplay between ideas and institutions might be drawn from this case study. (shrink)
