The Econometrics of Randomized Experiments (2016, background): “Bloom (1984), Zelen (1979, 1990), Baker and Lindeman (1994), Cuzick, Edwards, and Segnan (1997), contain early and independent discussions of the instrumental variables approach, some in the special case of one-sided non-compliance, and Imbens and Angrist (1994), Angrist, Imbens and Rubin (1996)…”
Better Late than Nothing: Some Comments on Deaton (2009) and Heckman and Urzua (2009) (2010, methodology): “Special cases of these methods had been used previously in the biostatistics literature, in particular in settings of randomized experiments with one-sided compliance (e.g., Zelen, 1979), but no links to the econometrics literature had been made.”
Instrumental Variables: An Econometrician's Perspective (2014, unknown): “However, there are also other antecedents, outside of the traditional econometric instrumental variables literature, notably the work by Zelen on encouragement designs (Zelen, 1979, 1990).”
Tutorial in Biostatistics: Instrumental Variable Methods for Causal Inference* (2014, background): “Monotonicity is automatically satisfied for single-consent randomized encouragement designs in which only the subjects encouraged to receive the treatment are able to receive it [46] (for this design, there are only compliers and never takers).”
Identification of Causal effects Using Instrumental Variables (1996, background): “One assumption that achieves this is random assignment to a control group denied treatment, so that Di(O) = 0 for all i (Zelen 1979; Angrist and Imbens 1991).”
Latent class instrumental variables: A clinical and biostatistical perspective (2015, methodology): “An early impetus for the development of the restricted latent class IV method was Zelen’s randomized consent design [22] involving randomization to either T0 or an offer of T1 with refusers receiving T0.”
Bayesian inference for causal effects in randomized experiments with noncompliance (1997, background): “…the discussion in Angrist, Imbens and Rubin (1996)], monotonicity is especially plausible in the context of a randomized trial of a drug whose access is restricted to units assigned to take it, implying Di 0 = 0 for all i, as in the application in Section 6 and in Zelen (1979) and Bloom (1984).”
Assessing the effect of an influenza vaccine in an encouragement design. (2000, background): “Similar ideas have been considered in other fields by, among others, Zelen (1979, 1990), Hearst et al. (1986), Holland (1988), Permutt and Hebel (1989), Robins (1989), Efron and Feldman (1991), Sommer and Zeger (1991), Baker and Lindeman (1994), McClellan and Newhouse (1994), Pearl (1995), and…”

The Effect of Grandparental Support on Mothers’ Labour Market Participation: An Instrumental Variable Approach (2014, unknown): “6 This situation is similar to the Zelen’s (1979) single-consent design where patients are randomly assigned to two groups: the first group of patients is only offered with the standard therapy, while patients in the second group can choose between the standard and new therapy.”
Practical statistics for medical research (1990, background): “(f) Zelen's design Lastly, Zelen (1979) proposed a variation on the randomized trial that seems to avoid problems associated with getting informed consent.”
Teaching Statistical Inference for Causal Effects in Experiments and Observational Studies (2004, background): “The IVE has been reinvented several times despite its old history (e.g., Bloom, 1984; Zelen, 1979).”
Robust, accurate confidence intervals with a weak instrument: quarter of birth and education (2005, background): “Holland (1988) has called this an encouragement design: subjects are randomly selected and encouraged to take the treatment, but it is the effects of the treatment itself, not the effects of encouragement, which are of interest; see also Zelen (1979) .”
