Give people money
Cash transfer
Cash-transfer interventions give recipients money — conditional on behaviors (Progresa), unconditional (GiveDirectly), or as part of a larger package (graduation programs). The mechanism is direct: the recipient gets resources and the autonomy to deploy them.

When it works
When the binding constraint on the outcome is income or liquidity. Strongest evidence is for poverty reduction, food security, child nutrition, and household stability. Effects on adult labor supply are typically small.
Watch out for
Pure cash works less reliably when the underlying problem is non-financial — addiction, mental health, community dysfunction. Conditional cash and 'cash plus' bundles (cash + services) often dominate pure cash in those settings.
