Costas Panagopoulos; Donald P. Green, 2010, "Spanish-Language Radio Advertisements and Latino Voter Turnout in the 2006 Congressional Elections: Field Experimental Evidence", https://doi.org/10.60600/YU/YILCPC, Yale Dataverse, V2
Because Hispanic voters are seldom targeted for campaign communication and because they listen to radio at higher rates than non-Hispanics, Spanish-language radio represents an attractive venue for testing whether nonpartisan mass media messages can mobilize voters. We conducted a large-scale, national field experiment testing the impact of nonpart... |

Jennifer K. Smith; Alan S. Gerber; Anton Orlich, 2011, "Self-Prophecy Effects and Voter Turnout: An Experimental Replication", https://doi.org/10.60600/YU/CLOPCO, Yale Dataverse, V2
Psychological research has found that being asked to predict one's future actions can bring about subsequent behavior consistent with the prediction but different from what would have occurred had no prediction been made. In a 1987 study, Greenwald, Carnot, Beach, and Young induced an increase in voting behavior by means of such a “self‐prophecy” e... |

Daniel Butler; David Broockman, 2012, "Do Politicians Racially Discriminate Against Constituents? A Field Experiment on State Legislators", https://doi.org/10.60600/YU/VAHSO4, Yale Dataverse, V2
We use a field experiment to investigate whether race affects how responsive state legislators are to requests for help with registering to vote. In an email sent to each legislator, we randomized whether a putatively black or white alias was used and whether the email signaled the sender's partisan preference. Overall, we find that putatively blac... |

Donald P. Green; Peter Aronow; Daniel Bergan; Pamela Greene; Celia Paris; Beth I. Weinberger, 2011, "Does Knowledge of Constitutional Principles Increase Support for Civil Liberties? Results from a Randomized Field Experiment", https://doi.org/10.60600/YU/ACPOWJ, Yale Dataverse, V2
For decades, scholars have argued that education causes greater support for civil liberties by increasing students’ exposure to political knowledge and constitutional norms, such as due process and freedom of expression. Support for this claim comes exclusively from observational evidence, principally from cross-sectional surveys. This paper presen... |

Alan S. Gerber; Donald P. Green; Edward H. Kaplan; Holger Lutz Kern, 2010, "Baseline, Placebo, and Treatment: Efficient Estimation for Three-Group Experiments", https://doi.org/10.60600/YU/QZU99O, Yale Dataverse, V2
Randomized experiments commonly compare subjects receiving a treatment to subjects receiving a placebo. An alternative design, frequently used in field experimentation, compares subjects assigned to an untreated baseline group to subjects assigned to a treatment group, adjusting statistically for the fact that some members of the treatment group ma... |

Alan S. Gerber; James G Gimpel; Donald P. Green; Daron R. Shaw, 2011, "How Large and Long-Lasting Are the Persuasive Effects of Televised Campaign Ads? Results from a Randomized Field Experiment", https://doi.org/10.60600/YU/UUUCUP, Yale Dataverse, V2
We report the results of the first large-scale experiment involving paid political advertising. During the opening months of a 2006 gubernatorial campaign, approximately $2 million of television and radio advertising on behalf of the incumbent candidate was deployed experimentally. In each experimental media market, the launch date and volume of te... |

Kevin Arceneaux; Alan S. Gerber; Donald P. Green, 2010, "A Cautionary Note on the Use of Matching to Estimate Causal Effects: An Empirical Example Comparing Matching Estimates to an Experimental Benchmark", https://doi.org/10.60600/YU/0IUZDB, Yale Dataverse, V2
In recent years, social scientists have increasingly turned to matching as a method for drawing causal inferences from observational data. Matching compares those who receive a treatment to those with similar background attributes who do not receive a treatment. Researchers who use matching frequently tout its ability to reduce bias, particularly w... |

Betsy Sinclair; Margaret McConnell; Donald P. Green, 2014, "Detecting Spillover Effects: Design and Analysis of Multilevel Experiments", https://doi.org/10.60600/YU/VYS8K9, Yale Dataverse, V2
Interpersonal communication presents a methodological challenge and a research opportunity for researchers involved in field experiments. The challenge is that communication among subjects blurs the line between treatment and control conditions. When treatment effects are transmitted from subject to subject, the stable unit treatment value assumpti... |

Donald P. Green; Daniel Winik, 2011, "Using Random Judge Assignments to Estimate the Effects of Incarceration and Probation on Recidivism Among Drug Offenders", https://doi.org/10.60600/YU/XPEJPZ, Yale Dataverse, V2
Most prior studies of recidivism have used observational data to estimate the causal effect of imprisonment or probation on the probability that a convicted individual is rearrested after release. Few studies have taken advantage of the fact that, in some jurisdictions, defendants are assigned randomly to judges who vary in sentencing tendencies. T... |

Kevin Arceneaux; Alan S. Gerber; Donald P. Green, 2011, "Comparing Experimental and Matching Methods Using a Large-Scale Voter Mobilization Experiment", https://doi.org/10.60600/YU/XD0LK8, Yale Dataverse, V2
In the social sciences, randomized experimentation is the optimal research design for establishing causation. However, for a number of practical reasons, researchers are sometimes unable to conduct experiments and must rely on observational data. In an effort to develop estimators that can approximate experimental results using observational data,... |
