(Explaining the Magnitude of the Transformational Recession) Comparative Economic Studies, Vol. 42, No. 1, Spring 2000, pp. 1-57. The arguments of this earlier article, however, are reconsidered in

Does liberalization matter? • Vietnam and China are similar in initial conditions and in
transition results (immediate growth of output without transformational recession) despite different reform strategies:
• Chinese reforms are the classical example of gradualism • Vietnamese reformers introduced shock therapy treatment
(instant deregulation of most prices and introduction of convertibility of dong) in 1989
• Differing performance of the former Soviet Union (FSU) states: • Baltic states are the champions of liberalization and
stabilization in the region. In the Baltics, however, output fell in the early 1990s by 36-60% and even in 2005, 10 years after the bottom of the recession was reached, was still below the pre-recession maximum.
• Uzbekistan is commonly perceived to be one of the worst procrastinators. However in Uzbekistan the reduction of output in 1990-95 totaled only 18% and the economy started to grow again in 1996
• By 2005 only two former Soviet republics - Uzbekistan and Turkmenistan - surpassed the pre-recession level of 1989
Reasons for recession: (1) Supply shock - change in relative prices

Explaining the magnitude of recession:
• Differences in performance during transition depend strongly on the initial conditions:
• The higher the distortions (militarization, over-industrialization, "under-openness" of the economy and the share of perverted trade flows), the worse is the performance
• The higher was GDP per capita before transition, the greater were distortions embodied in fixed capital stock, the more difficult it was to overcome these distortions to achieve growth
Explaining the magnitude of recession:
• Macroeconomic stability matters a great deal for economic performance
• Liberalization index does not appear to be important
• Changes in the institutional capabilities of the state have dramatic impact on performance
By the end of the 1990s most countries were already recovering from recession

Conclusions
• The impact of the speed of liberalization at the initial stage of transition, i.e. during the transformational recession, appears to be negative, if any.
• The reason for the negative impact is most probably associated with limited ability of the economy to adjust to new price ratios

Assumptions: size of non-competitive sector (NC) in the initial year = 20% of total output; net investment (s) = 10% of total output;
marginal capital productivity, output increase per unit of net investment (a) = 1/3.
Conclusions • At the recovery stage liberalization starts to affect
growth positively, whereas the impact of pre-transition distortions disappears. Institutional capacity and macroeconomic policy continue to be important prerequisites for successful performance.
• Liberalization at the recovery stage influences performance positively because it creates market stimuli without causing rapid collapse of output of ineff icient industr ies , which cannot be compensated fully by the rise of efficient industries due to investment constraints.
