Alan S. Gerber; Donald P. Green, 2011, "Correction to Gerber and Green (2000), Replication of Disputed Findings, and Reply to Imai (2005)", https://doi.org/10.60600/YU/ODL44F, Yale Dataverse, V2
This essay corrects the results reported in Gerber and Green 2000 and replies to Imai (2005). When data-processing errors are repaired, the original substantive findings from the New Haven experiment remain unchanged. As previously reported, brief phone calls do not increase voter turnout. The “correction” that Imai (2005) offers, which purports to... |

Susan D. Hyde, 2011, "The Observer Effect in International Politics: Evidence from a Natural Experiment", https://doi.org/10.60600/YU/KJE1VX, Yale Dataverse, V2
By pressuring governments to hold democratic elections and by becoming directly involved in the electoral process through technical assistance and funding or as election monitors, international actors now play a visible role in domestic elections and other democratic processes throughout the developing world. Although scholars have documented sever... |

Daron R. Shaw; Donald P. Green; James G. Gimpel; Alan S. Gerber, 2010, "Do Robotic Calls from Credible Sources Influence Voter Turnout or Vote Choice? Evidence from a Randomized Field Experiment", https://doi.org/10.60600/YU/ILUXSC, Yale Dataverse, V2
The effectiveness of prerecorded phone calls was assessed in the context of a Texas Republican primary election that featured a contest for state Supreme Court. Automated calls endorsing one of the judicial candidates were recorded by the sitting Republican governor and directed at more than a quarter million people identified as likely voters and... |

Gregory Huber; John S. Lapinski, 2011, "Testing the Implicit-Explicit Model of Racialized Political Communication", https://doi.org/10.60600/YU/UEYQIK, Yale Dataverse, V2
The Implicit-Explicit (IE) model of racial priming posits that implicitly racial messages will be more effective than explicitly racial ones in priming racial predispositions in opinion formation. Is the Implicit-Explicit model supported by existing data? In “Racial Priming Revived,” Mendelberg responds to our analysis of a pair of experiments in w... |

Costas Panagopoulos; Donald P. Green, 2011, "Field Experiments Testing the Impact of Radio Advertisements on Electoral Competition", https://doi.org/10.60600/YU/NTMEZU, Yale Dataverse, V2
Results from previous studies of campaign spending imply that equal-sized grants to both incumbents and challengers are a net benefit to challengers, who on average spend less money and derive greater marginal returns from each additional dollar. This study provides an experimental test of this proposition. Cities holding mayoral elections in Novem... |

Costas Panagopoulos, 2011, "Timing Is Everything? Primacy and Recency Effects in Voter Mobilization Campaigns", https://doi.org/10.60600/YU/STKD55, Yale Dataverse, V2
The timing of message delivery in political campaigns is a key component of strategy. Yet studies that examine the impact of message timing on political behavior are surprisingly rare. Although one recent study finds that appeals delivered closer to Election Day will be most effective (Nickerson, American Journal of Political Science 51(2):269–282,... |

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... |
