There is convincing evidence from a number of countries that cash transfers can reduce inequality and the depth or severity of poverty. For example, in Brazil a combination of cash transfer programmes accounted for 28 percent of the total fall in the Gini index (a summary measure of inequality) between 1995 and 2004….

Small but reliable flows of transfer income have helped poor households to accumulate productive assets; avoid distress sales; obtain access to credit on better terms; and in some cases to diversify into higher risk, higher return activities.

There is robust evidence from numerous countries that cash transfers have leveraged sizeable gains in access to health and education services…However, transfers have had less success in improving final outcomes in health or education.

Cash transfers therefore need to be complemented by ongoing sectoral strategies to improve service quality.
