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.
