The “V-factor”: Distribution, timing and correlates of the great Indian growth turnaround

We analyze a panel of output series for India, disaggregated by 15 states and 14 broad industry groups. Using principal components (Bai, 2004; Bai and Ng, 2004) we find that a single common “V-factor” captures well the significant shift in the cross-sectional distribution of state-sectoral output growth rates since the 2nd half of the 1980s. The timing of the turnaround implied by the V-factor is more closely related to the pattern of policy reforms than has been found in previous research. Regression-based analysis also provides some insights into the uneven distribution of the turnaround across Indian states.
