Abstract

Purpose The purpose of this study is to investigate the first time ever the effects of overall terms of trade, bilateral terms of trade and main commodity groups’ terms of trade on economic growth. Design/methodology/approach Augmented Dickey Duller and Philips Perron unit root tests and Johensan cointegration test have been applied by using annual time series data from 1974 to 2017. Dynamic ordinary least square and fully modified ordinary least square have also been used to perform sensitivity analysis. Findings The cointegration test confirm the positive long-run relationship between overall terms of trade (ToT) and economic growth. Country-wise results show that ToT with Australia, Bangladesh, Canada, Hong Kong, Japan, Kuwait, Malaysia, Singapore, Sri Lanka, UK and the USA have significant positive effect on economic growth.

In contrast, ToT with India, Norway, Saudi Arabia and Switzerland has insignificant effect on the economic growth of Pakistan. Product-wise results indicate that the product group namely, Chemical, Crude Material inedible except fuels, Manufactured and Minerals fuels and Lubricant found to be a significant positive effect on economic growth. However, Beverages and Tobacco, and Machinery and Transport product groups found to be significant negative impact on economic, while Food and Live animals found to be insignificant. Practical implications In general, it is suggested that the beneficial terms of trade are favorable for economic growth.
