Improbable does not mean impossible. Maybe this time really will be different. The U.S.S.R. wasn’t supposed to loosen the screws, and then it did. The Burmese junta was supposed to have battened down the hatches when it crushed the Saffron Uprising in 2007, and look where we are now, just a few years later. Although the safe money’s still on continuity in North Korea, there are sound reasons to believe the chances for political liberalization in the near future are improving.
Those “sound reasons” have to do with trade-offs inherent in the political economy of authoritarian rule, a topic I also discussed on this blog last fall in a post about Burma. Dictators want to preempt or squash domestic political threats, but they don’t like having to pay so much for security, and all that monitoring and repression trips up their economies, too. Those dilemmas mean that dictators might sometimes decide to relax repression when their opposition is weak and their economies are languishing, as is the case in North Korea today.
If you’re interested, please take a look at the piece in FP and let me know what you think. For more academic treatments of this topic, check out the 2007 conference paper on which I based my essay and this article by Georgy Egorov, Sergei Guriev, and Konstantin Sonin from the November 2009 issue of the American Political Science Review.
