This paper examines interactions and feedbacks between categories of capital
flows and economic growth in Turkey for the 1992:01-2009:08 period. Our
empirical analysis is based on a new version of the causality test of John
Geweke (1982, p. 77) and Yuzo Hosoya (1991, p. 88) in the frequency domain
proposed recently by J?rg Breitung and Bertrand Candelon (2006, p. 132). In
addition, using standard methods in spectral analysis, we decompose the total
covariance between capital flows and growth across main frequency bands and
capture lead/lag interactions between them. Some of our findings are as
follows: Variance decompositions over frequency bands reveal that variations
in individual capital flow categories are largely concentrated over high
(seasonal) frequencies. The nature of the interaction/feedback between growth
and capital flows varies significantly over frequency bands and subcategories
of flows. Over business cycle frequencies, two out of four subcategories of
inflows, short-term external borrowings and portfolio investments on
government bonds, drive growth whereas the other two components, long-term
borrowings and portfolio investments on shares, are driven by growth.
Furthermore, for the post-2001 financial crisis period we found significant
bidirectional causality between long-term external borrowings and growth
whereas portfolio investments, bond flows and short-term external borrowings
do not affect growth in the long run.
