Capital mobility in the Caucasus

摘要

This paper examines the degree of capital mobility in the countries of the Caucasus. I estimate a simple model developed in the seminal paper by Feldstein and Horioka (1980). I construct a panel of 6 countries of the Caucasus - Armenia, Azerbaijan, Georgia, Kazakhstan, Russia, and Turkey - and employ a panel cointegration approach. To that end, I make use of the Dynamic OLS (DOLS), Fully Modified OLS (FMOLS), and Pooled Mean Group (PMG) techniques for heterogeneous panels. Preliminary cross-dependency tests reject the presence of cross-sectional dependence. Panel unit root and cointegration tests confirm that investment and saving are non-stationary and cointegrated. The estimated long-run saving retention ratios using DOLS, FMOLS, and PMG are 0.90, 0.73, and 0.83, respectively. These results suggest that capital mobility in the Caucasus is very low. I put these findings in an international context and confirm that the Caucasus is considerably financially restrained compared to other regions. I also look at the country ratings of the Index of Economic Freedom (IEF) and find that my results work well in predicting the IEF rank. Finally, 1 discuss some implications for the region's policy-relevant issues such as financial integration, human capital mobility, cross-border trading, fiscal and monetary policy, solvency management, responsive consumption smoothing, and recession resistance.
