Required level of investment for fast economic growth: Stylized facts and policies

Abstract

To close the gap in economic development relative to the EU average, Serbian economy has to achieve significantly higher growth rates in comparison to other European countries over the longer period. Theoretical and empirical literature indicates that the level of investment in physical capital is one of the key determinants of the dynamics of economic growth. In this paper, based on data on investments and savings in Serbia and in 37 countries that in the previous three decades achieved an average GDP growth rate of over 5% per year (so-called fast-growing economies - FGE), we present and analyze relevant stylized facts. In the observed period, FGE had average total investments of 25.6% of GDP, of which 69% was private and 31% public investments, whereby private investments were predominantly domestic, which is associated with a high rate of gross domestic savings (of 27.4% of GDP). On the other hand, total investments in Serbia were 9.7% of GDP lower than the FGE average, which was a consequence of significantly lower public and domestic private investments, which was, among other things, a consequence of significantly lower domestic savings (by over 20% of GDP). As in the recent period there has been a noticeable increase in public investments in Serbia, in order to accelerate economic growth, it is necessary, in addition to maintaining them at a high level, to encourage a considerable increase in domestic private investments through economic measures policy and wider reforms of the general institutional environment, with the aim of having the total level of investments of over 25% of GDP over the next few decades.
