Between 1977, when India kicked Coke out the country, to 1993, 16 years, when Coke reentered the Indian market, India's GDP per capita (adjusted for inflation) increased 65%. During the next 16 years, from 1993 to 2009, GDP per capita increased increased 267% (multiplying by 3.6x). In the next 11 years, GDP per capita doubled again.
Had India not engaged in a multi-decade dalliance with central planning and pursued economic liberalization off the bat, India's per-capita GDP would be twice as high today.
