Here is a post that can be nominated for epic failure. Growth in nominal terms cannot be fuelled by inflation for long! The market forces balance things out. If that is the case, then a currency that is free float will not be valued at the same conversion rate.
With no proof you claim drop in purchasing power !
Similar to Pakistan's nominal growth, at least a part of India's nominal growth in per capita gdp and income is also driven by rising domestic inflation of over 10% and appreciating Indian rupee (5.5% from 48.32 in 2009 to 45.65 in 2010) from strong hot money inflows from the Fed's quantitative easing in the United States and elsewhere. India's FDI has declined by a third from $34.6 billion in 2009 to $23.7 billion in 2010. Its current account deficit is being increasingly funded by significant short-term capital inflows (FII up 66% from $17.4 billion in 2009 to $29 billion in 2010) rather than more durable foreign direct investment (FDI).
