It is an edited collection, I have an essay on inequality in the volume. Here is the Amazon link. Here is the book’s home page, which includes a full, free pdf. There are many famous contributors, including Jason Furman and Betsey Stevenson, Martin Feldstein, Justin Wolfers, Glenn Hubbard, George Borjas, Melissa Kearney, Casey Mulligan, and others. Here is Strain’s introduction and an organization of the book in sections. Self-recommending!
