How do trade barriers affect sectoral diversification and macroeconomic stability in developing countries?

Developing countries typically rely on exports of primary commodities and goods that are low in the production chain, to generate foreign currency. As a consequence, they are highly vulnerable to the frequent and persistent shocks that afflict these industries. A natural and often-proposed remedy is to diversify the economy. But while some countries have made progress in this direction, diversification remains a difficult challenge for many others. This paper examines the relationship between economic integration, sectoral diversification, and macroeconomic stability in developing economies.

The paper shows that:

  • lower trade barriers and diversification can have ambiguous effects on macroeconomic stability
  • lower trade barriers on primary goods increases volatility in the economy stemming from primary shocks, whereas lower trade barriers on domestic nonprimary goods have the opposite effects
  • lower trade barriers on foreign nonprimary goods enhances exchange rate stability while it increases the volatility of the aggregate variables
  • diversification in the form of a relatively smaller primary sector reduces volatility in the economy stemming from primary shocks
  • diversification in the form of equal distribution of resources between the nonprimary sectors may be counterproductive
  • investment in the nonprimary sector with lower trade barriers is shown to unambiguously promote macroeconomic stability.
