How Is Foreign Aid Spent? Evidence from a Natural Experiment
By: Eric D. Werker, Faisal Z. Ahmed and Charles Cohen
We use oil price fluctuations to construct a new instrument to test the impact of transfers from wealthy OPEC nations to their poorer Muslim allies. The instrument identifies plausibly exogenous variation in foreign aid. We investigate how aid is spent by tracking its...

Measuring the Scientific Effectiveness of Contact Tracing: Evidence from a Natural Experiment
By: Thiemo Fetzer and Thomas Graeber
Contact tracing has for decades been a cornerstone of the public health approach to epidemics, including Ebola, severe acute respiratory syndrome, and now COVID-19. It has not yet been possible, however, to causally assess the method’s effectiveness using a randomized...

Do Managers Matter? A Natural Experiment from 42 R&D Labs in India
