The analysis of the value of higher education contained in this report represents an important dimension of the P3 research agenda since measuring the value of educated workers can provide empirical context for understanding the importance of an educated and skilled workforce in a modern economy. In this report, the increases in individual earnings realized from enhanced educational attainment are measured and the benefits to the economy and society in general that are provided by a highly educated workforce are examined.

The demand for new workers in STEM (science, technology, engineering and mathematics) occupations in Arizona is a function of net job growth in these occupations in the state and the number of workers leaving STEM jobs in Arizona. Employees may leave their position for various reasons, including to retire, to move out of the state, or to change their profession. The supply of new workers in STEM occupations in Arizona is a function of the number of new college graduates in related majors, the number of workers moving to the state who are qualified to fill STEM jobs, and the number of Arizonans who are qualified to fill STEM jobs moving from a non-STEM to STEM occupation.

A landmark assessment of infrastructure needs in Arizona was produced by the L. William Seidman Research Institute in May 2008 for the Arizona Investment Council (AIC): "Infrastructure Needs and Funding Alternatives for Arizona: 2008-2032", that addressed infrastructure needs in four categories: energy, telecommunications, transportation, and water and wastewater. The information from the AIC report is a major input to the report that follows. Other types of infrastructure — most notably education, health care, and public safety — also are analyzed here to provide a more complete picture of infrastructure needs in Arizona. The goals of this report are to place Arizona’s infrastructure needs into national and historical contexts, to identify the changing conditions in infrastructure provision that make building Arizona’s infrastructure in the future a more problematic proposition than in the past, and to provide projections of the possible costs of providing infrastructure in Arizona over the next quarter century.
