“We talked to a man named Bernard Omondi who used the money — $1,000, paid in two installments — to buy a used motorcycle. He uses it as a taxi, charging his neighbors to ferry them around. Before he had the motorcycle, he says, he sometimes worked as a day laborer, but often couldn’t find any work at all. We talked to several other people who started small businesses. One family bought a mill to grind corn for their neighbors; another started selling soap and cooking oil. All of the people who got money from GiveDirectly lived in mud-walled houses with grass roofs. Many of them spent part of the money on metal roofs to replace the old, grass roofs.”
