One of the few email newsletters that I really enjoy is the Internet Scout Report from the Computer Science Department, University of Wisconsin, even though it generally has little to do with O.R.. However, the phrase "weighing costs and benefits" leapt out at me this week, in relationship to the costs for tax-payers of a new sports stadium in New York, and the related benefits. The email gave links to news stories about the issue. Obviously this is an area for O.R. analysis (not just economics) and modelling. But perhaps the most telling comment is that in the Sabernomics blog, where it records:
There is little evidence of large increases in income or employment associated with the introduction of professional sports or the construction of new stadiums.
