We present a model to explain why in the transition economies of Central an
d Eastern Europe an important output fall has been associated with price li
beralization. Its key ingredients are search frictions and Williamsonian re
lation-specific investment, implying that new investments are made only aft
er having found a new long-term partner. When all firms search for new part
ners, output may fall because of three effects: a) disruption of previous p
roduction links, b) a fall in investment, and c) capital depreciation due t
o the absence of replacement investment. We show that forms of gradual libe
ralization like the Chinese 'dualtrack' price liberalization may avoid the
transitory output fall.
