What Do We Learn about Voter Preferences from Conjoint Experiments?

  title={What Do We Learn about Voter Preferences from Conjoint Experiments?},
  author={Scott F. Abramson and Korhan Koçak and Asya Magazinnik},
  journal={American Journal of Political Science},
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

Candidate choice survey experiments in the form of conjoint or vignette experiments have become a standard part of the political science toolkit for understanding the effects of candidate

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

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,



Using Conjoint Experiments to Analyze Election Outcomes: The Essential Role of the Average Marginal Component Effect

Political scientists have increasingly deployed conjoint survey experiments to understand multidimensional choices in various settings. In this paper, we show that the average marginal component

Causal Inference in Conjoint Analysis: Understanding Multidimensional Choices via Stated Preference Experiments

Survey experiments are a core tool for causal inference. Yet, the design of classical survey experiments prevents them from identifying which components of a multidimensional treatment are

Robustness of the Multidimensional Voting Model: Candidate Motivations, Uncertainty, and Convergence*

This analysis demonstrates that important implications of the multidimensional voting model are robust to significant changes in the model's assumptions. (1) If candidates in the model are allowed to

Improving the External Validity of Conjoint Analysis: The Essential Role of Profile Distribution

Abstract Conjoint analysis has become popular among social scientists for measuring multidimensional preferences. When analyzing such experiments, researchers often focus on the average marginal

Do Voters Dislike Working-Class Candidates? Voter Biases and the Descriptive Underrepresentation of the Working Class

In most democracies, lawmakers tend to be vastly better off than the citizens who elect them. Is that because voters prefer more affluent politicians over leaders from working-class backgrounds? In

The Structure of American Income Tax Policy Preferences

In recent decades inequality in the United States has increased dramatically, but policy responses in terms of redistribution have been limited. This is not easily explained by standard political

Manipulation of Voting Schemes: A General Result

It has been conjectured that no system of voting can preclude strategic voting-the securing by a voter of an outcome he prefers through misrepresentation of his preferences. In this paper, for all
