A study of job losses in Missouri says the state has lost more than 31,000 jobs because of trade policies put in place during the Clinton and Bush Administrations. The Institute for Labor Sudies uses federal Labor Deparatment figures to determine job losses traceable primarily to agreements through the World Trade Organization and the North American Free Trade Agreement. The study says St. Louis, Kansas City, and St. Joseph are the hardest-hit cities. The Institute is a joint effort between the University of Misouri-Kansas City and Longview Community College in Kansas City.
