Few fields of empirical economic research offer virtual unanimity of findings. Yet, independent work on the economic impact of stadiums and arenas has uniformly found that there is no statistically significant positive correlation between sports facility construction and economic development (Baade and Dye, 1990; Baim, 1992; Rosentraub, 1994; Baade, 1996; Noll and Zimbalist, 1997; Waldon, 1997; Coates and Humphreys, 1999).
These results stand in distinct contrast to the promotional studies that are typically done by consulting firms under the hire of teams or local chambers of commerce supporting facility development. Typically, such promotional studies project future impact and almost inevitably adopt unrealistic assumptions regarding local value added, new spending, and associated multipliers. They often use a regional inputoutput model that depends on outdated technical coefficients which are treated as invariant to shifts in supply and demand (Center for Economic and Management Research, 1991; Deloitte & Touche, 1994, 1996; KPMG, 1996; Economic Research Associates, 1996; KPMG, 1998; C.H. Johnson Consulting, 1999).
