And you would be correct.
Bottom up is exactly how this nation should be rebuilt.
Bad anti-stimulus arguments
A number of conservative economists have been arguing against a stimulus plan centered on government spending. Fair enough. But one argument I keep reading bugs me: it’s the claim that spending-based stimulus is bad because economic theory tells us that a marginal dollar of private spending is better than a marginal dollar of government spending.
That’s just wrong; it’s a misreading of basic, Econ 101 level, economics.
Yes, the standard theory of consumer choice says that a consumer gains more utility if he or she gets to freely allocate a dollar of spending than if someone else makes the choices: I’d rather buy myself a $10 meal than have you feed me $10 worth of food that you select.
But that’s not what we’re talking about when we talk about stimulus spending: we’re not talking about the government buying consumption goods for the public at large. Instead, we’re talking about spending more on public goods: goods that the private market won’t supply, or at any rate won’t supply in sufficient quantities. things like roads, communication networks, sewage systems, and so on. And every Econ 101 textbook explains that the provision of public goods is a necessary function of government.
When we’re asking whether it’s better to have the government stimulate the economy or to try to stimulate private spending, we’re asking among other things whether a marginal dollar spent on public goods is worth more or less than a marginal dollar spent on private consumption. And there’s nothing, even in Econ 101, that clearly favors private spending on private goods over public spending on public goods.
In other words, the attempt to claim the authority of economics for the idea that stimulus in the form of tax cuts is better, at a microeconomic level, than stimulus in the form of infrastructure spending is a case of bait and switch. Don’t fall for it.
