While a large majority of countries mobilized existing programs and/or administrative databases to expand support to new beneficiaries, countries without such programs or databases were severely limited in their capacity to respond. Leveraging the Covid-19 shock as an opportunity to leapfrog and innovate, various low-income countries used new sources of data and computational methods to rapidly develop -level welfare-targeted programs. This paper reviews both crisis-time programs and regular social protection operations to distill lessons that could be applicable for both contexts. It examines three programs from the Democratic Republic of Congo, Togo, and Nigeria that used geospatial and mobile phone usage data and/or artificial intelligence (AI), particularly machine learning methods to estimate the welfare of applicants for individual-level welfare targeting and deliver emergency cash transfers in response to the pandemic. Additionally, it reviews two post-pandemic programs, in Lomé, Togo and in rural Lilongwe, Malawi, that incorporated those innovations into the more traditional delivery infrastructure and expanded their monitoring and evaluation framework. The rationale, key achievements, and main challenges of the various approaches are considered, and cases from other countries, as well as innovations beyond targeting, are taken into account. The paper concludes with policy recommendations and promising research topics to inform the discourse on leveraging novel data sources and estimation methods for improved social assistance in and beyond emergency settings.en-USCC BY-NC 3.0 IGOSOCIAL PROTECTION AND LABORPOVERTYSOCIAL ASSISTANCECASH TRANSFERSACCESS TO SOCIAL PROGRAMSADAPTIVE SOCIAL PROTECTIONSOCK RESPONSETECHNOLOGYINNOVATIONSG2P (GOVERNMENT TO PERSON) PAYMENTNOVEL DATA SOURCECALL DETAIL RECORDS (CDR)SATELLITE IMAGERYMACHINE LEARNINGARTIFICIAL INTELLIGENCETARGETINGGEOSPATIAL TARGETINGEMERGENCY RESPONSESCOVID-19 RESPONSESNO POVERTYSDG 1GOOD HEALTH AND WELL-BEINGSDG 3DECENT WORK AND ECONOMIC GROWTHSDG 8INDUSTRY, INNOVATION AND INFRASTRUCTURESDG 9PEACE, JUSTICE AND STRONG INSTITUTIONSSDG 16Working Paper (Numbered Series)World Bank10.1596/41548
