Evidencia en acción

La evidencia de las evaluaciones aleatorizadas está cambiando la forma en que entendemos y abordamos los problemas relacionados con la pobreza. Los formuladores de políticas, profesionistas y fundaciones de todo el mundo están utilizando cada vez más estos aprendizajes en las políticas y programas sociales. Más de 400 millones de personas han sido alcanzadas por programas que se escalaron después de ser evaluados por investigadores afiliados a J-PAL. Muchos más se han beneficiado de las diversas y amplias formas en que la evidencia puede informar las políticas que se describen a continuación.
