This study attempts to evaluate the economic impact of a few major social protection programmes in India. Using the Social Accounting Matrix (SAM) framework, this study computes the output, employment, income, and revenue impacts of government expenditure on three social security measures—the Mahatma Gandhi National Rural Employment Guarantee Act, the Indira Awas Yojana, and the National Social Assistance Programmes—in 2011-12. The study has constructed a 32-sector SAM for India for the year 2007-08. The household categories are based on expenditure classes. The exercise shows that these programmes have a significant impact on output across different sectors of the economy, on incomes of different household classes in urban and rural areas, employment across different sectors of the economy, and even on revenue generation to the government.</p
