More Powerful Cluster Randomized Control Trials

Marcos Vera-Hernandez (UCL), joint with Brendon McConnell

Thursday 15 September 2022 13:00 - 14:00

Many of our seminars and public events this year will continue as in person or as hybrid (online and in person) events. Please check our website listings and Twitter feed @STICERD_LSE for updates.

Unless otherwise specified, in-person seminars are open to the public.

Those unable to join the seminars in-person are welcome to participate via zoom if the event is hybrid.


About this event

Balanced experimental designs, in which the number of treatment and control units are the same, do not maximize power subject to a cost constraint when treatment units are more expensive than control ones. Despite this, such balanced designs are the norm in economics. This paper describes methods to optimally choose the number of treatment and control clusters, and the number of units within treatment and control clusters, allowing for full flexibility. We use three archetypal examples from the development literature to illustrate the magnitude of the power gains, which lie between 8.5 and 19 percentage points.

This seminar series is jointly organized by the IFS, STICERD, and UCL.

IFS/STICERD/UCL Development Economics Work In Progress seminars are held on Thursdays in term time at 10:00-14:00, at the IFS, unless specified otherwise.

Seminar organisers: Oriana Bandiera (STICERD, LSE), Imran Rasul (UCL), Britta Augsburg (IFS) and Jonathan Weigel (LSE).
