%0 Journal Article %T Randomized Experiments and Reality of Public and Nonprofit Organizations: Understanding and Bridging the Gap %A Nicola Belle %A Paola Cantarelli %J Review of Public Personnel Administration %@ 1552-759X %D 2018 %R 10.1177/0734371X17697246 %X This article aims to contribute to the methodological advancement of experimental public administration, a nascent and promising literature stream. The article discusses the assumptions behind the theory of experimentation and the consequences of their violation; the main types of experimental designs (i.e., lab experiments, artefactual, framed, and natural field experiments); discrete choice experiments, neglected so far in our discipline for no good reason; the computation of optimal sample sizes; and the procedures for dealing with noncompliance in field experiments. The article concludes by providing tips to help public administration scholars bridge the gap between randomized trials and reality %K randomized control trials %K experiments %K experimental designs %K external validity %K discrete choice experiment %K optimal sample size %K noncompliance %U https://journals.sagepub.com/doi/full/10.1177/0734371X17697246
