About the Seminar
Recent years have seen important advances in the design and analysis of both randomized experiments and quasi-experiments. A particular focus has been empirical tests of the conditions under which nonrandomized experiments can approximate answers from a randomized experiment. Such efforts have a long history in fields such as medicine (Gilbert, McPeek, and Mosteller, 1977), psychology (Smith and Glass, 1978), and economics (LaLonde, 1986). Recent work is prompted by such factors as evidence-based practice and theoretical advances such as Rubin's causal model.
This webinar reviews illustrative studies that demonstrate the direction such work is taking and the results that seem to be emerging in regards to nonrandomized control group designs, regression discontinuity designs, and interrupted time series designs.
