J. Newman et al., USING RANDOMIZED CONTROL DESIGNS IN EVALUATING SOCIAL SECTOR PROGRAMSIN DEVELOPING-COUNTRIES, The World Bank research observer, 9(2), 1994, pp. 181-201
Seven case studies-from Bolivia, Colombia, Indonesia, Mexico, Nicaragu
a, Taiwan (China), and Turkey-demonstrate the feasibility of conductin
g rigorous impact evaluations in developing countries using randomized
control designs. This experience, covering a wide variety of settings
and social programs, offers lessons for task managers and policymaker
s interested in evaluating social sector investments. The main conclus
ions are: first, policymakers interested in assessing the effectivenes
s of a project ought to consider a randomized control design because s
uch evaluations not only are feasible but also yield the most robust r
esults. Second, the acute resource constraints common in developing co
untries that often make program rationing unavoidable also present opp
ortunities for adopting randomized control designs. Policymakers and p
rogram managers need to be alert to the opportunities for building ran
domized control designs into development programs right from the start
of the project cycle because they, more than academic researchers or
evaluation experts, are in the best position to ensure that opportunit
ies for rigorous evaluations are exploited.
