Convergence club empirics: Some dynamics and explanations of unequal growth across Indian states

This paper documents the convergence of incomes across Indian states over the period 1965 to 1998. It departs from traditional analyses of convergence by tracking the evolution of the entire income distribution, instead of standard regression and time series analyses. The findings reveal twin-peaks dynamics—the existence of two income convergence clubs, one at 50 per cent, another at 125 per cent of the national average income. Income disparities across states seem to have declined over the 1960s, only to increase over the subsequent three decades. The observed polarization is strongly explained by the disparate distribution of infrastructure, and that of education, and to an extent by a number of macroeconomic indicators; that of capital expenditure and fiscal deficits.
