Rise of the Randomistas: How a new wave of controlled trials is helping set social and economic policies

What’s the best way to help poor people: give them food or cash? This kind of socioeconomic question might seem impossible to answer.

The use of such trials has exploded in the past two decades, measuring everything from the effect of public health measures such as deworming tablets to poverty alleviation schemes such as food subsidies, and now help determine international aid.
