Macro-economic and trade link models of South Asian countries: an investigation for regional trade expansion

The paper examines the macroeconomic structure of South Asian countries-Bangladesh, India, Nepal, Pakistan and Sri Lanka. It also explores the possibility of trade expansion among these countries by examining the macro-economic and regional trade link models based on time series data of 28 years. The study finds that there are inter-country differences in production and consumption patterns, investment behaviour, tax and non-tax structures in these countries. Hence there is a considerable scope for trade expansion among the South Asian countries. The study also confirms that aggregate regional consumption and regional GNP increase significantly with the increase of aggregate regional trade, and the consumption and income elasticities are 1.70 and 1.61 respectively. The study also exhibits that the GNP of Bangladesh, Nepal, Pakistan and Sri Lanka, with limited exceptions, are significantly increased with the increase of their exports to the region. So these countries would definitely be benefited from the regional trade expansion. The same may be true for India if the smuggled trade is prevented or reduced, and true economic factors, keeping aside political conflicts, dominate for regional trade policy.
