What happened: income-share concentration by major Indian family business groups

A World Bank Economic Review study titled “Business Groups, Concentration and Market Power in India” argues that large family business groups continue to dominate corporate India’s income streams even after economic liberalisation and increasing competition. The study is authored by Simon Commander along with other academics.

The study reports these patterns for Reliance, Adani, Birla, Om Prakash Jindal, and Tata groups:

- From 2001 to 2020, these five family business groups collectively controlled more than 60% of business revenue.

- The Birla group’s revenue share declined steadily over the period.

- The shares of other listed family groups rose over the same period.
