Hoosier better paid in KY?

This from an IBJ news update that came earlier this week:

Hoosiers fare better working in Kentucky
Indiana residents who work in Kentucky earn $500 to $1,500 more than Kentucky residents working in Indiana . Hoosier nurses make $7,000 more in Kentucky , for example, and educators make $2,500 more. Most of the disparity is explained by better-paying jobs available in Louisville , according to The Evening News of Jeffersonville .
