Research objective and methodology
- Objective: Shed new light on the determinants of growth by addressing the blunt and weak instrument problems in the empirical growth literature.
- Instrumental strategy:
- Propose average values of the same endogenous variable in neighboring countries as an instrument for each endogenous variable.
- Characterize these instruments as variable-specific and time-varying—namely, “sharp”—and strong.
Key findings
- Export sophistication is identified as the only robust determinant of growth among the standard growth determinants examined.
- Other standard determinants considered include:
- Human capital
- Trade
- Financial development
- Institutions
- Implication from results:
- Other growth determinants may be important to the extent they help improve export sophistication.

Core takeaway for policy and research
- Focus on policies and interventions that improve export sophistication, as this characteristic is found to be the robust driver of economic growth in the authors’ empirical framework.
- Use of neighboring-country averages as variable-specific, time-varying instruments provides a methodological approach to mitigate blunt and weak instrument problems in growth regressions.
