תקציר	Social cost-benefit analysis (social CBA) is the economic appraisal of development projects from the standpoint of society as a whole rather than the private investor. It values every input and output at its shadow (economic) price — the true opportunity cost or social worth, which in distorted developing-country markets diverges from observed market prices — then discounts the resulting net benefit stream at a social discount rate to compute an economic net present value (ENPV) and economic internal rate of return (EIRR). The method was systematised for developing countries by Ian Little and James Mirrlees and by the parallel UNIDO guidelines.	Cash transfer evaluation is the body of impact-evaluation practice used to measure the effects of giving money directly to poor households — conditional on behaviours such as school enrolment and clinic visits (CCTs) or unconditional (UCTs) — on consumption, schooling, nutrition, health, and broader welfare. Pioneered by Mexico's PROGRESA/Oportunidades programme in the late 1990s, which built a randomised phase-in into its rollout, the field has produced some of the most influential causal evidence in development economics and now spans dozens of countries and hundreds of studies.
