In a sharp regression discontinuity design
WebWe use a regression-discontinuity design to study the effects of double blocking sixth-grade students in reading and mathematics on their achievement across three years of middle school. To identify the effect of the intervention , we use sharp cutoffs in the test scores used to assign students to double blocking. We find large, positive, and ...

Background: The regression discontinuity design (RDD) is a quasi-experimental approach used to avoid confounding bias in the assessment of new policies and interventions. It is applied specifically in situations where individuals are assigned to a policy/intervention based on whether they are above or below a pre-specified cut-off on a …

There are generally accepted two kinds of RDD studies. There are designs where the probability of treatment goes from 0 to 1 at the cutoff, or what is called a “sharp” design. And there are designs where the ...
WebRegression discontinuity (RD) research designs exploit precise knowledge of the rules determining treat-ment. RD identi–cation is based on the idea that in a highly rule-based world, some rules are arbitrary and therefore provide good experiments. RD comes in two styles, fuzzy and sharp. The sharp design can be Web2.2 The Sharp Regression Discontinuity Design It is useful to distinguish between two general settings, the Sharp and the Fuzzy Re-gression Discontinuity (SRD and FRD from …
WebIn a traditional regression-discontinuity design (RDD), units are assigned to treatment and comparison conditions solely on the basis of a single cutoff score on a continuous assignment variable. The discontinuity in the functional form of the outcome at the cutoff represents the treatment effect, or the average treatment effect at the cutoff.
Web“sharp” design, in which all subjects receive their assigned treatment or control condition, and the “fuzzy” design, in which some subjects do not.

Both sharp and fuzzy designs are supported. Estimation is accomplished using local linear regression.

In reality, however, cutoffs are often not strictly implemented (e.g. exercised discretion for students who just fell short of passing the threshold) and the estimates will hence be biased. In contrast to the sharp regression discontinuity design, a fuzzy regression discontinuity design (… dark yellow cardigan sweater
