In backdrop of Economics Nobel announcement, letter panning RCT surfaces
For popularising randomised control trials, especially in economics, they should get a ban from doing research rather than the Nobel Prize!
Banerjee, Duflo and Kremer have been awarded the 2019 Nobel Memorial Prize in Economics for their contribution to reviving development economics, particularly through the popularisation of “randomised control trials” (RCTs) that break larger questions about policy interventions into smaller, easier to test studies.
In a letter sent to British publication Guardian in August 2018, the economists had said that relying on RCTs to guide welfare and aid spending will lead to short-term, superficial and misplaced policies. These economists include past Nobel laureates like Angus Deaton of Princeton University, Joseph Stiglitz of Columbia University and James Heckman of Chicago University.
To begin with, the efficacy of RCT is zero, as expected and as shown in evaluations.
