He said the fact that inequality trends vary so greatly among countries, even when they share similar levels of development, highlights the important role of national policies in shaping inequality.
He also noted that the challenge for India is how to share growth without destroying its environment.
According to the 'World Inequality Report 2018', inequality rose substantially in India following profound transformation in the economy that centred on the implementation of deregulation and opening-up reforms.
The report, launched globally recently, was coordinated by economists Facundo Alvaredo, Lucas Chancel, Thomas Piketty, Emmanuel Saez and Gabriel Zucman and shows unequal impacts of globalisation over past 40 years.
According to the report, income inequality in India has reached historically high levels.
It said: "In 2014, the share of national income accruing to Indias top 1 per cent of earners was 22 per cent, while the share of the top 10 per cent was around 56 per cent."
It noted that the temporary end to the publication of tax statistics between 20002010 by Indian government highlights the need for more transparency on income and wealth statistics that track the long-run evolution of inequality.
