Abstract
This study aims to quantify heterogeneity in how people think about trading off various dimensions of redistribution policy. I ask individuals to consider a number of scenarios where the government performs redistribution in a number of different ways, with a number of different economic consequences, and ask whether across these scenarios, people find the redistribution to be worthwhile. The answers to these questions will inform a model of the distribution of weights people assign to various dimensions of redistribution policy, which can in turn be used to quantify the proportion of people who would in principle be in favor of different counterfactual policy proposals. I aim to then connect the results of this experiment with a structural model, predicting the economic impacts of various income guarantee proposals to find the set of politically feasible income guarantee programs.

Interventions

Intervention(s)
Each individual in my experiment will receive a survey. The first half of the survey asks about basic demograhpic information. The second half of the survey asks individuals.

Primary Outcomes

Primary Outcomes (end points)
The primary outcomes of interest will be the binary decisions of individuals in responding to the hypothetical redistribution outcomes asked about in the survey are desirable.

Experimental Design

Experimental Design
Each subject will fill out a simple, short survey. Part 1 will collect basic demograhpic information about subjects (Gender, Age, Marital Status, Children, Ethnicity/Race, US Citizenship, State of Residence, Education, Employment Status, Income, President Vote, Political Identity).

In the second part, I will ask them to answer a series of questions of the following form:
"Suppose that the government spent $1,000, and as a result transfers $Y {in cash/in value through currently existing welfare programs} on top of current benefits to a household who 1) currently makes income I, 2) will respond to the transfer by reducing labor supply by D. {In addition, the household in question has a job which is consider to be at high risk of being automated due to AI., In addition, the household in question has a job which is not considered to be at high risk of being automated due to AI.} Do you think this transfer was a net positive or net negative for society?"

From question to question, I vary Y, I, D, as well as the discrete options in braces and record the survey-taker's response to each question.

Randomization Method
Randomization is done through the JavaScript code underlying the Qualtrics survey.
Randomization Unit
Questions will be randomized at the individual-question level.
Was the treatment clustered?
No

Experiment Characteristics

Sample size: planned number of clusters
2500 subjects
Sample size: planned number of observations
2500 subjects answering 10 binary choice questions.
Sample size (or number of clusters) by treatment arms
The distribution of "treatments" is drawn from a continuum of values, so this question is poorly defined for my setting.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
The purpose of this experiment is not to estimate a specific treatment effect but instead to generate enough variation to well-identify the parameters of a structural model of political preferences. This structural model's parameters are ultimately pinned down by conditional choice probabilities of the form Pr[Yes | Y,I,D,characteristics] as defined above. Assuming that Y,I,D are normalized to be i.i.d. Uniform random variables, this involves estimating 4 3-dimensional CCP functions. I give a lower bounds for how precisely this CCP can be nonparmaetrically estimated. Assume a naive kernel-based estimator where to make a prediction for a given conditioning variable, we take an average of all observations within a 0.1 radius of a given point. With 25,000 observations (10 questions x 2,500 participants), this gives roughly 240 observations to estimate this CCP, which therefore has gives us a margin of error of roughly +/- 5% of the true CCP.
