Dex. Fair enough. The question is why do you think that? Here I'm going to get into the technical crap and say that it's a question of what we econ types call marginal propensity to consume (MPC). If I give someone a dollar, what percentage of it will they spend, and what will they save? Depending on who you give the money to, that number will be higher or lower. Rule of thumb, the less income you have the less you save. So you have to answer the question, where does that money end up? Given any particular procurement program, some will end up in the hands of the workers and downstream suppliers, some will end up in the hands of management and the company's owners. That'll be a mix of high and low(er) MPCs. However, if you pay unemployment benefits or public worker salaries with that same pile of cash, the average will be higher. So looking strictly at direct stimulative impact, you're really better off giving it away, as long as you give it away to the right people.
Of course, there's other benefits like supporting those industries and such that may push you to support procurement. And to be honest, I'm all for making GSA's fleet more fuel efficient.
Kaleigh: I'm sure you understand this, but I want to make very clear that no serious economist anywhere will claim that you can escape the business cycle. You can nudge it around the edges and mitigate the highs and lows, but it'll be around forever. It's just how human psychology interacts with markets.
As for politicians, I'd say it's not so much them as the incentives our political structure puts into place, with its myriad veto points and the rewards that accrue to ideological rigidity.
