What studies discuss how money flows internally and permanently out of an economy? This seems tangential here.<p>I recall an article/conversation long ago about how open source consulting projects keep money local. IIRC, the argument was that paying someone to develop open source software for a government project leads to that money being cycled around six times inside the local economy, as opposed to money leaving the local economy.<p>For example, if you buy Oracle's database (and associated consulting) for that municipal government accounting project for the city government of Smalltown, USA, then all that money leaves that economy permanently.<p>If instead the city council of Smalltown, USA can be convinved to hire a few weird local Perl programmers to build it that money will go into their bank account at the local credit union. That credit union will then loan out that money, and multiply it inside the local economy there. That Perl programmer will go down to the pub, and spend money there, and on groceries (and not Amazon), etc.<p>There are complications to doing it local (Perl programmers aren't great salespeople), but in Oregon we were bitten by Oracle and it turned out to not be cost effective at least: <a href="https://www.oregonlive.com/politics/2016/09/post_183.html" rel="nofollow">https://www.oregonlive.com/politics/2016/09/post_183.html</a>. Oregon tax payers paid $240M to Oracle. Oracle settled for $100M, but let's be straight: $75M of that is Oracle software. You cannot find Oracle software being exchanged for pizza at any brew pubs here.<p>It seems like buying local is keeping money local. But, I never hear people talking about it that way, other than in that random open source advocacy discussion.<p>I cannot find that link, and perhaps it was only a dream I had, but this makes sense to me logically.
