Reminds me of the joke: Someone asserts "All odd integers greater than 1 are prime". The mathematician says: "Three is prime. Five is prime. Seven is prime. Nine is not prime. The assertion is false." The physicist says: "Three is prime. Five is prime. Seven is prime. Nine is composite. Eleven is prime, Thirteen is prime. Nine is probably an error. The generalization is probably true." The engineer says: "Three is prime. Five is prime. Seven is prime. Nine is prime..."
Any "outlier" counter-example disproves an unqualified universal statement.
No "basic principles of economics" support the generalization that tax-funded infrastructure projects generate positive returns. Your examples are laughable. The first: a study funded by the construction industry! Really?
Arguments via disconnected anecdote as well as those from personal incredulity and unsupported but implied source bias are generally without merit or measurable weight, ...again, you seem stuck in pathos with no substantive logos in your position.
Care to try citing supporting facts and figures as originally requested?
1. That would depend on the
road,
bridge,
dam, park, etc. Some air, water, food, equipment, etc. regulations are cost-effective. Some are not.
I'm not sure that "cost effective" was ever an issue of discussion, but I would be interested in your definition and consideration of this qualification. The issue being discussed is whether or not there is a positive return on investment to the public from general public infrastructure projects, and whether or not public infrastructure projects in general are an effective stimulus to the economy.
2. If we have to define "infrastructure" (and we do), then it's clear that details matter. Is a park "infrastructure"? Why is this obvious, if a sports arena is not so clearly "infrastructure". I would direct your attention to the Eduardo Zambrano quote that I supplied earlier in this discussion.
I know little about professor Zambrano's expertise or body of work, but the quote you provided seems completely disconnected from anything being discussed and is apparently directed at command economy issues in a totalitarian type governmental system headed by an incompetent authoritarian head of state. As to the definition of infrastructure, I am comfortable with the standard economic definition:
"Infrastructure for the 21st Century" -
http://www.nap.edu/openbook.php?record_id=798&page=2
Infrastructure – highways, streets, roads, and bridges; mass transit; airports and airways; water supply and water resources; wastewater management; solid-waste treatment and disposal; electric power generation and transmission; telecommunications; and hazardous waste management – and the combined system these modal elements comprise. A comprehension of infrastructure spans not only these public works facilities, but also the operating procedures, management practices, and development policies that interact together with societal demand and the physical world to facilitate the transport of people and goods, provision of water for drinking and a variety of other uses, safe disposal of society's waste products, provision of energy where it is needed, and transmission of information within and between communities.
I consider parks and preserves to be essential to maintaining and providing natural recreational value, but also because they help maintain some persistence of the the core biological diversity that is essential for sustained, qualitative life upon our planet. If your definition of "parks" is limited to a quarter acre playground or public garden, I might be persuaded to reconsider their inclusion.
Sports arena's and convention centers, primarily because these are almost always joint ventures between private capital and public support with private profit goals in the use of such facillities and private investment through matching special issue bond measures, I'm not sure that these meet your own qualification of public infrastructure. In general, I would agree that such venues often stimulate microcosms of economic growth and value and can occassionaly broaden and attract greater economic benefit to a city through cultural and business enrichment.
3. Why is not the White Sea/Baltic canal "infrastructure"? For that matter, why is not a special regime Kolyma lead mining camp "infrastructure"? Some government created it. That should be certification enough that such a project expresses the will of the people, for some of the government enthusiasts around here.
p.s., The moonbase promise is a major consideration against Gingrich. It indicates a fondness for grand projects and a desire to display himself thinking big thinks for us little people to admire. Just like grand irrigation projects, rural electrification projects, or public housing projects.
Primarily, the problem is with "Public" infrastructure. In the US Public = Government ("...of the people, by the people, for the people,..."), this isn't true in many (if not most) other nations. If you are seriously offering these examples as legitimate public infrastructure projects that should be highlighted in any examination of the value of public works and infrastructure projects, then there is little sense in making any further attempts at achieving a rational discourse on this issue.
