Political scientists frequently interpret the results of conjoint experiments as reflective of majority preferences. In this paper we show that the target estimand of conjoint experiments, the AMCE, is not well-defined in these terms. Even with individually rational experimental subjects, unbiased estimates of the AMCE can indicate the opposite of the true preference of the majority. To show this, we characterize the preference aggregation rule implied by AMCE and demonstrate its several…

Using Conjoint Experiments to Analyze Elections: The Essential Role of the Average Marginal Component Effect (AMCE)

Political scientists have increasingly deployed conjoint survey experiments to understand multi-dimensional choices in various settings. We begin with a general framework for analyzing voter…

Corruption Information and Vote Share: A Meta-Analysis and Lessons for Experimental Design

Debate persists on whether voters hold politicians accountable for corruption. Numerous experiments have examined whether informing voters about corrupt acts of politicians decreases their vote…

Primary Divisions: How Voters Evaluate Policy and Group Differences in Intraparty Contests

While central to theories of polarization and primary elections, surprisingly little evidence shows that partisans favor candidates who take ideologically consistent issue positions, above other…

Abstract Partisan and affective polarization should have observable consequences in Canada, such as bias in political information search and processing. This article presents the results of three…

Using Machine Learning to Test Causal Hypotheses in Conjoint Analysis

Conjoint analysis is a popular experimental design used to measure multidimensional preferences. Researchers examine how varying a factor of interest, while controlling for other relevant factors,…

Subjects, Trials, and Levels: Statistical Power in Conjoint Experiments

Conjoint analysis is an experimental technique that has become quite popular to understand people's decisions in multi-dimensional decision-making processes. Despite the importance of power analysis…

Inequality, Information, and Income Tax Policy Preferences in Austria and Germany1

Inequality has increased over recent decades in many advanced industrial democracies, but taxes have rarely become more progressive. One possible explanation for the lack of a policy response is…

City limits to partisan polarization in the American public

Abstract How pervasive is partisan sorting and polarization over public policies in the American public? We examine whether the barriers of partisan sorting and polarization seen in national politics…

DCPS or Sidwell Friends? How Politician Schooling Choices Affect Voter Evaluations

Voters often rely on informational shortcuts, such as the background traits of politicians, to decide which candidates to support at the ballot box. One such background trait is family composition,…
