Why transition economies did worse than others in 2008-09 recession?

While developing countries as a group did better than developed countries in 2008-09 recession, transition economies – former communist countries – experienced the largest reduction of output. Out of 42 countries that experienced negative growth in 2007-09, 13 were transition economies. In fact, 4 out of 5 most affected economies were former communist countries (Latvia, Estonia, Ukraine, Lithuania). The hypothesis is that these transition countries (1) suffered more than the others from the sudden outflow of capital and (2) did not manage this outflow particularly well. The rule of thumb was that large outflows of capital, especially coupled with negative trade shocks, suppressed economic activity. But if the shocks were relatively small (up to 3% of GDP change in trade and capital account from Q2 2008 to an average of subsequent 3 quarters), it was possible to mitigate them through devaluation (not allowing foreign exchange reserves to drop by the same amount). If the shocks were large, even devaluation did not allow to avoid output fall.
