Mazmanian and Sabatier advocate the importance of legislation for successful policy implementation. Scholars such as Perkmann have identified structural factors that affect regional cooperation. Under Workforce Investment Act, legislative and structural factors in obtaining regional cooperation across traditional state and local government boundaries are analyzed in nine U.S. Midwestern metropolitan regions. Results from this study suggest there are policy design and structural factors such as the focus of actors; same year implementation of the act; and the amount of hierarchical integration of administrative entities that can be enhanced to increase the likelihood that regional cooperation will occur under WIA.
