Web2.1 Assumptions of RDD As with any evaluation design RDD requires some basic assumptions. The first is about the unique feature of the assignment strategy to the treatment and control groups. It is assumed to be fully known in advance, and solely based on a score variable S. Study subjects are assigned to the treatment group if their score is ...

The eligibility index should be continuous around the cut-off point to prevent individuals from manipulating their eligibility index to increase their chances of being included in or excluded from the program.
WebThe RD design has to be classified as a quasi-experimental design. Although the RD design has a clear structure of an experimental design, it lacks the random assignment feature. … The intuition behind the RDD is well illustrated using the evaluation of merit-based scholarships. The main problem with estimating the causal effect of such an intervention is the homogeneity of performance to the assignment of treatment (e.g. scholarship award). Since high-performing students are more likely to be awarded the merit scholarship and continue performing well at the same time, comparing the outcomes of awardees and non-recipients would lead to an upward bi…
WebWe point out that although many researchers invoke the local randomization assumption, also called the as-if-random assumption, it tends to be more stringent than the continuity assumption, which is the key identification assumption of the RD design.
