J-PAL North America, a research‑policy hub within MIT's Department of Economics, has launched a free public Homelessness Evaluation Resource Hub funded by Google.org. The hub gathers evergreen multimedia materials that equip decision‑makers with basic tools to use evidence for reducing homelessness and improving housing stability.\ \ Homelessness is both a cause and a consequence of poverty and inequality. Rigorous empirical research is essential for identifying effective solutions, yet constraints on time, funding, and other resources often block access to high‑quality evidence. J-PAL North America seeks to lower these barriers by offering evaluation tools, case syntheses, and methodological guides, thereby expanding the literature on what works to curb homelessness.\ \ To mark the launch, a virtual event will be held on Oct. 27. The hub’s scientific advisor is David Phillips, research professor of economics at the University of Notre Dame and director of the Wilson Sheehan Lab for Economic Opportunities (LEO). Phillips noted that collaboration between practitioners and academics creates a shared language, allowing teams to focus on continuous learning and better outcomes for communities.\ \ The hub is organized around two core activities: Using Evidence and Generating Evidence. The former offers two‑page policy briefs that synthesize experimental and quasi‑experimental findings on five established interventions—Housing First, emergency financial assistance, case management, legal aid in housing court, and housing vouchers—and includes J-PAL North America’s 2019 Evidence Review, Reducing and Preventing Homelessness: Lessons from Randomized Evaluations, which aggregates results from 40 rigorous evaluations of 18 programs. The latter hosts seven modules covering foundational concepts of impact evaluation—ethics, data and measurement, randomization opportunities—and demonstrates how to apply them in the homelessness sector.\ \ These resources build on two decades of J-PAL experience training over 30,000 learners and incorporate insights from nearly 20 informational interviews with leading researchers, government officials, and service providers in the region. Development was a close collaboration with Notre Dame’s LEO team, with special thanks to David Phillips for his meticulous guidance.\ \ The hub is now live and freely accessible.\ \ Review
