Nieuwe studie bewijst effect aanpak Max Foundation

Een nieuwe studie van de Yale School of Management bewijst het effect van de aanpak van Max Foundation om toiletgebruik in Bangladesh te bevorderen. Een combinatie van het motiveren van gemeenschappen en subsidies voor de allerarmsten blijkt het beste. Details van de studie kan je vinden op de website van Science Magazine en Yale School of Management.

Some insights:

  • Research in rural Bangladesh on different marketing treatments—community motivation and information; subsidies; a supply-side market access intervention; and a control—in a cluster-randomized trial
  • The behavior change plus subsidy program increased toilet access by 9.4% relative to the control group; increased ownership by 20%, suggesting that some households that had been sharing toilets moved to individual ownership; and reduced open defecation by 22%. The behavior change program alone had no effect on toilet ownership, nor did the supplier intervention.
  • The results also show that the decision to invest in a toilet happens at the community level
  • “Subsidies are not as effective when the programs are targeted to individuals,” says Mobarak. “When a lot of people are subsidized together, that’s when individuals actually move. It’s more effective to go into a village and run programs that target the whole community jointly, and pay attention to the fact that people’s investment decisions are interlinked.”
