Business reforms and total factor productivity in Vietnamese manufacturing

Vietnam implemented reforms in the 2000s to ease start-up of new businesses with dramatic effect on firm entry and market competition. This study examines firm level data for the period 2000-2010 to analyze total factor productivity (TFP) in connection with the reforms, adopting a semi-parametric technique developed by Wooldridge (2009) and Petrin and Levinsohn (2012) to measure TFP. Intensified competition is hypothesized to have driven convergence of TFP within industrial sectors as technologies best suited to Vietnamese market conditions became more widely implemented. The evidence strongly supports this hypothesis with convergence found for 16 of the 17 sectors analyzed. Further, comparison of TFP growth rates between the first and second half of the decade shows mixed results by sector and region. More often than not, TFP growth is seen to have slowed over time. This suggests that competition acted not only to push low TFP firms to exit the market or raise productivity, it also discouraged use of technologies that may have been overly advanced and not cost efficient for Vietnam.
