ISPS Data Archive

Part of the Yale Institution for Social and Policy Studies (ISPS) Dataverse, the ISPS Data Archive includes “replication packages” (i.e., data, analysis code, requisite documentation, and other associated materials) for research supported by ISPS. Replication packages have been reviewed to enable long-term usability using the YARD tool. Read about our approach to curating for reproducibility.

How Large and Long-Lasting Are the Persuasive Effects of Televised Campaign Ads? Results from a Randomized Field Experiment Apr 8, 2026 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...
A Cautionary Note on the Use of Matching to Estimate Causal Effects: An Empirical Example Comparing Matching Estimates to an Experimental Benchmark Apr 8, 2026 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...
Detecting Spillover Effects: Design and Analysis of Multilevel Experiments Apr 8, 2026 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...
Using Random Judge Assignments to Estimate the Effects of Incarceration and Probation on Recidivism Among Drug Offenders Apr 8, 2026 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...
Comparing Experimental and Matching Methods Using a Large-Scale Voter Mobilization Experiment Apr 8, 2026 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,...
Comparative Inheritance Taxation Database Apr 8, 2026 Kenneth Scheve; David Stasavage, 2011, "Comparative Inheritance Taxation Database", https://doi.org/10.60600/YU/ZKGHPB, Yale Dataverse, V2 In this article we use an original data set to provide the first empirical analysis of the political economy of inherited wealth taxation that covers a significant number of countries and a long time frame (1816–2000). Our goal is to understand why, if inheritance taxes are often very old taxes, the implementation of inheritance tax rates significa...
Economics and Policy Preferences: Causal Evidence of the Impact of Economic Conditions on Support for Redistribution and Other Ballot Proposals Apr 8, 2026 Eric Brunner; Stephen L. Ross; Ebonya Washington, 2011, "Economics and Policy Preferences: Causal Evidence of the Impact of Economic Conditions on Support for Redistribution and Other Ballot Proposals", https://doi.org/10.60600/YU/F5NQ4A, Yale Dataverse, V2 Using California ballot proposition returns and exogenous shifts to labor demand, we provide the first large-scale causal evidence of the impact of economic conditions on policy preferences. Consistent with economic theory, we find that positive economic shocks decrease support for redistributive policies. More notably, we find evidence of a need f...
Were Newspapers More Interested in pro-Obama Letters to the Editor in 2008? Evidence from a Field Experiment. Apr 8, 2026 Daniel Butler; Emily Schofield, 2010, "Were Newspapers More Interested in pro-Obama Letters to the Editor in 2008? Evidence from a Field Experiment.", https://doi.org/10.60600/YU/OAYRDW, Yale Dataverse, V2 During the 2008 presidential election, the authors submitted letters to the editor at 100 major U.S. newspapers as part of a field experiment to test whether interest in the letter depended on which candidate the letter supported. The authors find, contrary to what charges of a liberal media bias would suggest, that newspapers expressed more intere...
Do Congressional Candidates Have Reverse Coattails? Evidence from a Regression Discontinuity Design Apr 8, 2026 David Broockman, 2010, "Do Congressional Candidates Have Reverse Coattails? Evidence from a Regression Discontinuity Design", https://doi.org/10.60600/YU/IOEQKE, Yale Dataverse, V2 Although the presidential coattail effect has been an object of frequent study, the question of whether popular congressional candidates boost vote shares in return for their parties’ presidential candidates remains unexplored. This article investigates whether so-called "reverse coattails" exist using a regression discontinuity design with congres...
Getting Out the Vote in Local Elections: Results from Six Door-to-Door Canvassing Experiments Apr 8, 2026 Donald P. Green; Alan S. Gerber; David W. Nickerson, 2010, "Getting Out the Vote in Local Elections: Results from Six Door-to-Door Canvassing Experiments", https://doi.org/10.60600/YU/B9TZNZ, Yale Dataverse, V2 Prior to the November 6, 2001 elections, randomized voter mobilization experiments were conducted in Bridgeport, Columbus, Detroit, Minneapolis, Raleigh, and St. Paul. Names appearing on official lists of registered voters were randomly assigned to treatment and control groups. A few days before Election Day, the treatment group received a face-to-...
