While I can't offer an academically sound study on this, simply because it is not possible, particularly at this late date, to set up a controlled experiment that could provide some more insight. I don't even think that TIGER is particularly good example BTW, because it has the added complexity of extremely questionable data being imported which is not the case in such a What we can do is compare areas which have seen early large imports of basic infrastructure to areas that have that are roughly the same cultural background and population density with nearby areas that haven't. We have numerous cases where this is possible (not for the USA), big and small, for example the Netherlands and the Canton of Solothurn. All of the cases I've looked at in such comparison indicate a weaker local community than comparable regions which didn't have such imports. Further we have additional material in the early simulations that Matt Amos did that indicate that this is not unexpected given some assumptions about editor motivation. So while there is no completely conclusive proof that large infrastructure imports early in the development of a community have a negative impact, it is not unexpected and the body of evidence clearly supports it. I should point out that none of the above is in any way new, just conveniently ignored. Simon
