Our guest on this edition of ST is Peter Fisher, research director at the Iowa Policy Project, who co-wrote a recently published paper, "A Well-Educated Workforce Is Key to State Prosperity," for the Economic Analysis and Research Network. This network is a project of the Economic Policy Institute, or EPI, which defines itself as "a nonpartisan think tank that seeks to broaden the public debate about strategies to achieve a prosperous and fair economy." Fisher's report affirms that the educational attainment of a given state's workforce is clearly and consistently linked with both productivity and median wages in that state --- and thus this report was referred to by David Blatt, our friend and colleague at the Oklahoma Policy Institute, in a blog entry that he posted last week. As Fisher explains in our via-telephone interview, whether we're talking about Iowa, Oklahoma, or any other state in the union, investing in education --- as opposed to, say, offering tax breaks --- is, from a statistical standpoint, the first and best step on the path to prosperity.
