The study looked at how changes in corporate savings in India since 2002 have affected firm profitability. By comparing data from 2001, 2007, and 2010, researchers found that there was an overall increase in profitability for all firms after 2002. This increase was mainly due to changes in factors like capital structure, business group affiliation, firm size, age, growth opportunities, and market share. The study suggests that encouraging business group affiliation may not always be beneficial for firm performance in India, as the costs may outweigh the benefits. Size and market share were found to be important factors in explaining changes in profitability, especially in terms of return on assets.
