Conditional Cash Transfers

How programs that pay poor families on the condition that children attend school and visit clinics spread from Mexico and Brazil to much of the world.

A conditional cash transfer, often shortened to CCT, is a government program that gives money to poor households on the condition that they take certain actions, usually keeping children enrolled in school and attending regular health checkups. The approach aims to do two things at once: reduce poverty today by raising family income, and reduce poverty tomorrow by building human capital, the health and skills that let children earn more as adults.

Mexico’s experiment

The modern CCT began in Mexico in 1997 with a program called Progresa, later renamed Oportunidades and then Prospera. It paid mothers in poor rural families a monthly grant if their children attended school at least most days and if family members visited health clinics. Grants for secondary school were slightly larger for girls, because girls were more likely to drop out.

What made Progresa famous was how it was evaluated. Because the government could not reach every village at once, it randomly selected which eligible communities would start first. That allowed researchers to compare similar villages with and without the program. They found that enrollment rose, especially for secondary school and especially for girls, and that children in participating families were healthier. The strong evidence helped the program survive changes of government and inspired copies worldwide.

Brazil and beyond

Brazil launched Bolsa Família in 2003, combining earlier programs into one. At its height it reached around a quarter of the population and is widely credited with contributing to a fall in poverty and inequality, at a cost of roughly half of one percent of national income. Similar programs spread across Latin America and then to countries such as the Philippines, Indonesia, Turkey, Bangladesh and Pakistan.

A family's decision about school

Picture a 13 year old girl in a rural area who could earn about 20 dollars a month working in the fields. Keeping her in school means giving up that income, which is a real sacrifice for a poor household. Now suppose a conditional cash transfer pays the family 25 dollars a month as long as she attends school. The financial reason to pull her out disappears. Over several years, she completes secondary school, which research suggests will raise her lifetime earnings well beyond what the grant cost.

Conditions versus no conditions

A lively debate asks whether the conditions are necessary. Unconditional cash transfers give money with no strings attached. Supporters argue that poor families know their own needs best, that monitoring conditions is costly, and that conditions can unfairly penalize the poorest households, such as those living far from any school. Studies of unconditional transfers in Kenya and elsewhere have found that recipients mostly spend the money sensibly, on food, livestock, home improvements and small businesses, rather than on alcohol or tobacco, contrary to a common fear.

On the other hand, a randomized study in Malawi found that conditions did produce larger gains in school enrollment than unconditional grants, while unconditional grants did better on some other outcomes, such as reducing early marriage among girls who had already left school. The answer may depend on the goal.

Getting targeting right

Every cash transfer program must decide who qualifies, a challenge called targeting. Because many poor households have no formal income records, governments often use surveys of household assets, such as the type of roof or whether the family owns a refrigerator, to estimate who is poor. Mistakes happen in both directions: some poor families are wrongly excluded, and some better-off families slip in.

Assuming cash makes people stop working

A frequent worry is that giving money to poor families will make adults work less. A review of randomized studies of several government cash transfer programs by economists at Harvard and MIT found no systematic evidence that the transfers discouraged work. When the amounts are modest, families generally use them to supplement their earnings, not replace them.

Key takeaways
  • Conditional cash transfers pay poor families for keeping children in school and visiting clinics.
  • Mexico's Progresa, launched in 1997, was rigorously evaluated using a randomized rollout.
  • Brazil's Bolsa Família reached around a quarter of the population at modest cost.
  • Unconditional transfers are cheaper to run and also show strong results, though conditions may boost schooling further.
  • Deciding who qualifies, called targeting, is a major practical challenge.
