Ohio's manufacturing industry sector partnerships (ISP) are economic development and workforce development efforts that rely on community development inputs. The authors posit that graduates of regional, sector-led, industry-specific workforce training programs constitute a common pool resource, as described by Elinor Ostrom, because while hiring graduates is rival, it is not excludable. This creates a workforce version of the tragedy of the commons because these programs often have experiential learning components in workplaces and require funding support, mentoring, and the long-term commitment of company leaders to a partnership. The training programs will flounder if participating employers do not earn a return on their resource expenditures. The output of the partnership program is trained workers, while its primary outcome is the production of goods and services. The economic mobility of the recipients of ISP training is a by-product, or secondary outcome, of the partnership's activities
