Homelessness in the United States is a pressing issue that requires increased research on effective strategies to address it and foster long-term housing stability. With grant funding from Google.org—Google’s philanthropic arm—the Abdul Latif Jameel Poverty Action Lab (J-PAL) North America's Bay Area Evaluation (BAE) Incubator supported Bay Area service providers with implementing and evaluating cash transfer programmes to assess their impact on homelessness and housing stability. J-PAL North America’s Evaluation Incubators build the base of rigorous evidence by supporting organizations and government agencies to transform their research questions into comprehensive evaluation designs. The model provides selected partners with funding, technical assistance and training on evaluation design, and connections to J-PAL’s network of expert researchers.
