Investment in Transition Economies

Summary

All centrally planned economies suffered from overinvestment. Due to low capital productivity, reasonable growth rates in output could be maintained only with high investment/GDP ratios. Nevertheless, the sharp reduction in investment during transformational recession and its slow growth during subsequent recovery are viewed as negative phenomena, since transition economies offer numerous opportunities to increase output with relatively small targeted investment.

This paper seeks to develop and test two major hypotheses. The first one explains the behavior of aggregate investment during transition: we find that changes in external financing (current account balance), in the government budget deficit and in the institutional capacity of the state (as measured by the share of government revenues in GDP) explain up to 75% of the variations in investment/GDP ratios during transition, while the progress in reforms (cumulative liberalisation index) and in privatisation (share of the private sector in GDP) do not matter a great deal. With respect to sources of investment financing, there is some evidence that better investment performance is supported by budgetary funds, by credits to the private sector and by the strength of the stock market, whereas foreign aid is a substitute rather than a complement (i.e., it is negatively related to investment) and the inflow of foreign direct investment is not important.

The second hypothesis deals with the impact of investment on economic performance as measured by changes in GDP during transition: we find that differences in performance arc, in great part, associated not with investment patterns, but with varying marginal capital productivity. The latter in turn is determined mainly by differing magnitudes of restructuring required in various countries, i.e., by the distortions in industrial structure and trade patterns inherited from central planning, and by the institutional capacity of the state (as measured by the share of shadow economy and government revenues in GDP). The degree of liberalisation in this case appears to be a relatively important determinant of capital productivity, while the rates of inflation are not.
