Post 8 — You Get the Cash

Every week I take one real case — a company, a government program, a league — and show how the reward shaped the behavior. Welcome to Behavior Follows Rewards.

Going to school had always been possible. Now it had a reward attached. The behavior changed.

Brazil stopped arguing that poor families should send their children to school and started paying them to.

In Brazil in 2003, the richest twenty percent of the population held fifty-eight percent of the wealth. The bottom sixty percent held four. This had been true for generations.

Economists had a term for it. They called the country Belindia — a tiny Belgium of prosperity surrounded by an India of poverty. The expression had been in circulation since the 1970s.

The cycle ran on its own logic. Families in poverty needed income now. Children worked instead of going to school. Without school, the next generation started where the last one had ended. The poverty reproduced itself because the structure reproduced itself.

A new president took office. He had one idea.

We will pay you. A small amount, every month. In return: the children go to school.

The program was called Bolsa Família — Family Allowance. Launched on October 20, 2003, by President Luiz Inácio Lula da Silva, it was not a grant. It was not charity. It was a conditional transfer.

Each eligible family received a debit card. The card was charged monthly — but only if the family met its obligations. Children between six and fifteen had to attend school at least eighty-five percent of the time. Young people aged sixteen and seventeen were subject to separate conditionalities. Vaccination records had to be current. Pregnant women had to attend prenatal checkups. The payment and the behavior were linked. Explicitly. On paper. In practice.

The amount was modest. For a family in extreme poverty with two children, the maximum monthly benefit was roughly R$242 — the equivalent of about eighty to one hundred dollars at the time. It was not designed to replace income. It was designed to change the calculation.

Going to school had always been possible. Now it had a reward attached. The reward arrived when the behavior occurred — not a year later, not at a manager’s discretion, not in an annual review. Monthly. Directly. If the school confirmed attendance, the card charged.

The behavior changed.

School enrollment increased. For children in recipient families, the dropout rate fell by 7.8 percentage points. For fifteen-year-old girls — the group most at risk of leaving school to work or marry — the odds of being in school rose by twenty-one percent. Vaccination rates improved. Prenatal care utilization rose. Children who had been kept home to contribute to household income were in classrooms.

The poverty fell.

In the first ten years, Brazil more than halved its extreme poverty rate — from 9.7 percent of the population to 4.3 percent. By 2015, the share of Brazilians living below the international poverty line had dropped from 13 percent to 3 percent. The Gini coefficient — the standard measure of income concentration, where higher means less equal — fell by fifteen percent, a reduction the World Bank called impressive.

One in four Brazilians was receiving the transfer. More than ninety percent of the benefit cards were issued in women’s names. The program cost roughly half a percent of GDP. Critics had predicted that giving cash directly to families would reduce work incentives. It did not. Labor force participation was unaffected.

Within a decade, more than a hundred and twenty delegations had visited Brazil in a single year to study how the program worked. Brazil formalized this exchange through the Brazil Learning Initiative for a World Without Poverty — a joint program with the World Bank and the United Nations Development Programme to share Bolsa Família’s design and implementation with governments adapting similar programs. It has since been replicated in more than forty countries.

Step outside the story for a second. Most of the cases in this series are stories about a gap -- between what a system says it wants and what it actually pays for. This one isn't. Bolsa Familia is what happens when the gap closes: the reward and the goal point the same direction, and the outcome stops being a surprise.

You may have seen a version of this work — a structure where the incentive and the desired outcome pointed the same direction, and the behavior followed without anyone having to be told twice. That is not luck. That is design.

Here's the mechanism — the same one that runs through this series:

A reward is attached to a behavior. The behavior follows the reward.

In the Behavior Follows Rewards series’ Post 6 — Wells Fargo, the reward was account volume. The behavior was fraud. In Post 7 — Northern Ireland, the reward was fuel consumed. The behavior was heating empty barns. In Post 4 — Sears, the reward was unit profit and loss for each division. The behavior was competing against each other instead of against the competition. In Post 3 — Olympic badminton, the reward was a favorable bracket draw. The behavior was deliberate losing. In each case, the reward produced behavior — not the behavior the designers intended, but the behavior the structure actually rewarded.

Bolsa Família is the same pattern. The government wanted children in school. It attached a reward to school attendance. The children went to school.

When every element of a system points toward the same outcome, the behavior it produces is not surprising. It is inevitable. Bolsa Família did not work because its designers were especially virtuous, or because Brazil had conditions that other countries lack. It worked because the structure was aligned. The reward was explicit. The link between reward and behavior was clear to everyone the system touched. The payment arrived when the behavior occurred.

That is the test — not whether the intention was right, but whether every element of the structure pointed the same way.

Ask yourself: what behaviors in your organization do you want, and what are you conditioning them on? Brazil attached a cash transfer to behaviors it needed — school attendance, healthcare visits — and behavior followed the reward. Wanting the behavior is not the same as designing the system that produces it.

If you are working through an incentive design challenge in your organization — trying to understand why a policy, initiative, or team isn’t doing what you designed it to do — that is the work. Advisory Services →

If you were a mother in northeast Brazil in 2003 — earning next to nothing, your children’s labor the only thing between your family and hunger — would you have chosen school attendance over work on the strength of a government’s moral argument alone? Or did it take a check?

Last time: In Northern Ireland, a renewable heat program paid operators per unit of heat generated. The operators ran heaters in empty buildings for years. The government could not cover what the reward had set in motion.

Next: Britain offered Afghan farmers money to destroy their poppy crops. The reward created a reason to grow more. The program expanded for four years. Poppy cultivation rose every year.

In development — a performance ranking where being the standout performer made you the biggest risk in the room; a talent standard built around a single question and what that question actually selected for; a grading system designed to produce excellence that rewarded something else entirely. More on the way.
