A new book co-authored by UC Davis sociologist Erin Hamilton charts the lives of 34 women and men who have returned to Mexico in the last two decades after years living in the U.S. Their stories convey the deep sense of loss they feel as they struggle to rebuild their lives.

The U.S. government’s recent shift to a non-cooperative negotiating strategy has used the tactic of threatening to increase the costs of not agreeing to U.S. terms, according to a UC Davis expert in international negotiations. While non-cooperation is far from unprecedented in international negotiations, it could make U.S. negotiations in the future much more challenging.

New research in economics looks back at the history of U.S. tariffs and finds that from 1870 to 1909, tariffs made U.S. businesses weaker, not stronger. Tariffs reduced the average size of businesses while increasing the price of what they produced. Because tariffs work the same way they did 100 years ago, these findings have relevance today.
