Saving-investment dynamics and capital mobility in the BRICS, 1970-2013

Abstract

This study examines the saving-investment relationship and the extent of capital mobility in the BRICS over the period 1970-2013. However, saving and investment are cointegrated, but the error correction model exhibits structural instability with the onset of different country-specific crisis and over the period of global financial crisis in 2008. The inclusion of interactive dummy variables reveals that current period pass through of saving to investment is negative and statistically significant for the post-1980 period in Brazil, and over 1990s and 2000s in South Africa, indicative of capital mobility. Furthermore, the global financial crisis affects the exchange rate depreciation in Russia
