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

Abstract

The paper examines themacroeconomic structure of SAARC countries, i.e. 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 the SAARC countries. Hence, there is considerable scope for trade expansion among the SAARC 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 benefit from the regional trade expansion. The samemay 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.
