Abstract
The recent Venezuelan migration crisis has seen over 3 million people move to other Latin-American countries. Even though Uruguay has been the recipient of only a small fraction of them, the number of Venezuelan migrants has been steadily and significantly increasing since 2014. Though the general climate is not of overt xenophobia in the general population, there is still signs of dissatisfaction from some Uruguayans considering that the newcomers are taking relatively low-skilled jobs in an economy with increasing unemployment rates.

In this project, we conduct a lab experiment to examine differences in trust levels towards immigrants, and whether allowing for prior free-form communication can help diminish any such differences.

Primary Outcomes

Primary Outcomes (end points)
Trust: Amount of money sent by "Player 1" to "Player 2" in the trust game (Berg et. al. 1995).
Primary Outcomes (explanation)

Secondary Outcomes

Secondary Outcomes (end points)
Reciprocity: Amount of money sent back by "Player 2" to "Player 1" in the trust game (Berg et. al. 1995).
Secondary Outcomes (explanation)

Experimental Design

Experimental Design
Participants will play 4 rounds of the trust game (Berg et. al. 1995).
The basic setup consists on two players (sender, receiver) that have an initial endowment of $X. The sender chooses what fraction of her endowment $Y she’ll send to the receiver. $Y is tripled on its way to the receiver, and he now decides how much of his $X+3Y to send back to the sender.

There are two between subject treatments:
- No communication
- Communication

Pairs will be re-matched every round.
Immigrants will always be assigned the "receiver" role, and every "sender" will be matched with an immigrant in at least one of the four rounds. All assignments are random otherwise.

Before making each rounds' decision, players will receive a card with demographic information of their counterpart (gender, age, education level, neighborhood, and nationality).

In the communication treatment the receivers will be able to write a message to be shown to all 4 senders they play with. This message will be delivered together with the demographic information card.
Experimental Design Details
Randomization Method
Matchings will be pre-randomized by subject number, and subject numbers will be assigned randomly.
Randomization Unit
Individual
Was the treatment clustered?
Yes

Experiment Characteristics

Sample size: planned number of clusters
We plan to recruit 500 individuals (250 senders, 250 receivers).
The final number will depend on attrition and demographic balance.
Sample size: planned number of observations
2000 observations
Sample size (or number of clusters) by treatment arms
No Communication: 250
Communication: 250
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
