Editors' Introduction

We are pleased to present another exciting issue of the SIGecom Exchanges. The Exchanges seeks to keep the EconCS community abreast of relevant news and exciting research directions. This Summer 2025 issue has some of both. On the news side, we have a letter from the SIGecom executive committee, summarizing ongoing and upcoming SIG activities, and a recap of the 2025 Winter Meeting on Generative AI and Market Design. We also have three letters, a research survey, and an annotated reading list, previewed below.
