Saving and investment rates in the BRICS countries

The first decade of the new millennium witnessed the arrival of five large, fast-growing emerging economies on the global stage. These countries, Brazil, Russia, India, China and South Africa, collectively known as the BRICS countries, have achieved robust growth and steadily outpaced the advanced economies in the last quarter of a century or so. In spite of their recent slowdown, on the basis of their demographics, vast natural resources, physical and human capital accumulation and overall progress, they are likely to remain the engines of global economic growth and development for some time in the future. In the light of the rising role of BRICS countries in the world economy, this paper aims to study the relationship between their domestic saving and investment rates in the vein of Feldstein–Horioka but on a country-by-country basis using time-series econometric techniques. The results suggest that the basic Feldstein–Horioka regression is misspecified for each BRICS country. The preferred autoregressive-distributed-lag specifications imply that capital is not perfectly mobile internationally in any of the BRICS countries, but it is more mobile in South Africa and Russia than in India, Brazil and China.
