This article presents a cost-benefit analysis of Britain’s Employment Retention and Advancement (ERA) demonstration, which was evaluated through the first large-scale randomized control trial in the UK. ERA used a combination of job coaching and financial incentives in attempting
to help long-term unemployed men and low-income lone parents sustain employment and progress in work once they were employed. Using both administrative and survey data, ERA’s effects on benefits and costs were estimated through impact analyses, which exploited the experimental design.
The findings indicated that ERA was cost beneficial for long-term unemployed adult men, but not for lone parents. The key findings appear robust to sensitivity tests. Uncertainty, as implied by the SEs of the estimated impacts, was addressed through a Monte Carlo analysis, an approach seldom
previously used in cost-benefit analyses of social programs.
