以下为英文征召全文：

The Social Innovations Group at the University of Michigan is looking for participants for a remote interview study.

If you are *new to the U.S.* and have used any website/phone app (Facebook groups, NextDoor, WhatsApp, WeChat, LINE, etc.) for local buy-and-sale groups, please consider joining our study. Local buy-and-sale refers to transactions of items (e.g., used furniture) and services (e.g., gigs) in your local area for a small amount of money or free.

We will ask about your experience in local buy-and-sell in our study. If you are interested in the study, please sign-up here: https://umich.qualtrics.com/jfe/form/SV_6J4Dv6BjTCQkqqO. We will review your response in a few business days and reach out to you if you are eligible for the study. You will receive a $30 USD e-gift card after your full participation in the interview.

If you have any questions about the study, feel free to contact us: um-exchange-study@umich.edu. Our study is approved by the UM-IRB and to be exempted from human subjects research regulations (HUM00177209).
