Economic growth due to export externalities: a spatial econometric analysis for Russian regions, 2003–2008
This paper empirically investigates the effects of vertical export diversification on economic growth in Russian regions. First, we explore differences in vertical export diversification across Russian regions and analyze whether the relationship between intra-industry vertical export diversification and economic growth takes place at the regional level in 2003-2009. Using OLS and GMM estimators and controlling for a quality differences when calculating productivity level of export goods, we show that initial specializing in low-quality goods (with implied low- productivity level) leads to higher subsequent economic growth. The possible explanation is that, regions with low-quality goods in their export basket are able to improve productivity in relatively shorter terms (comparing with the situation of export discovery) and as the result grow faster. However, as it was shown, these effects of initial specialization in low-quality products on faster economic growth do matter only for regions, which are far from technology frontier.
