Abstract amended in January 2024: This paper provides new evidence on the macroeconomic impact of cash transfers in developing countries. Using a Bartik-style identification strategy, the paper documents that Brazil's Bolsa Familia transfer program leads to a large and persistent increase in relative state-level GDP, formal employment, and informal employment. A state receiving 1% of GDP in extra transfers grows 2.2ppts faster in the first year, with R00,000 of extra transfers generating five formal- equivalent jobs, half of which are informal. Consistent with a demand-side mechanism, the effects are concentrated in non-tradable sectors. However, an open-economy New Keynesian model only partially captures the high multipliers estimated.
