Abstract
We estimate perceptions of taxes and support for redistribution for a representative urban population in Mexico. Furthermore, we analyze whether people adjust the degree of preferred redistribution when information is provided on scenarios in which high-income people pay more taxes. To do this, we create four treatment groups and a control within a sample of 3,060 participants. Each group received information about a scenario in which the highest income group in the country will pay 60%, 50%, 40% or 20% of their income in taxes.

Interventions

Intervention(s)
We create four treatment groups and a control within a sample of 3,060 participants. Each group will receive an information card. Four groups receive the same information about:
a) Mean monthly income received by the lowest and the highest income deciles in Mexico.
b) Taxes as proportion of income paid by the lowest and the highest income deciles in Mexico.
Then, in order to measure if interviewees change their preferences for redistribution, each group will receive information in which the highest income group in the country will pay 60%, 50%, 40% or 20% of their income in taxes.

Experimental Design

Experimental Design
For the sample selection, we follow a stratified multi-stage probability sampling with four sampling stages:
• Selection of AGEBs by simple random sampling.
• Selection of housing blocks by simple random sampling.
• Selection of dwellings through systematic sampling with random start.
• For respondent selection, a simple roster will be made of all the members of the household from 25 to 69 years old based on the date of birth. The member whose birthday is closer to the date of the interview will be chosen from those in the household.
For the experimental design, the interviewees will be randomly assigned to one of the four control groups or the control one.
Experimental Design Details
Randomization Method
The interviewees will receive a message or information card in the questionnaire used; followed by five different questions that will be randomly distributed among five subgroups of interviewees of the same size by a software.

Survey is carried out by a third-party firm. By information protection laws, the firm does not share individual identifiers with researchers (name or specific address)
