I’m tired of people saying “virtually every economist will agree that…” Do any of you know any economists?
I am getting a PhD in the subject this summer and have taught full time for nearly a year now.
Economists agree on some general things, but not on things as specific as this. The answer should be… ready?
It depends.
It depends on the marginal productivity of the government sector (which is realistically impossible to know), and the marginal productivity on the private sector (which is much easier to guess at). Ideally, you would spend on both sectors such that $1 of spending gets the same marginal productivity in both sectors. But again, it is hard to know what the marginal productivity of the public sector (this is ‘decided’ by voters in an ‘ideal’ world).
Consider the absurdity of saying tax cuts create jobs, all the time. If we cut taxes to $0, no taxes whatsoever, we have no national defense. In several instances of history, this would have led to very bad results. Employment would be the least of our concerns had the USSR ended up dominating Europe, Asia, and South America. Had we stuck with no military in that situation, whose to say whether we would exist (same for WWII).
That’s an extreme example. We kindof agree on the extremes - that 100% taxation is definitely bad for growth, and that 0% is not great either.
There are two major fallacies that goes unspoken in the reply to this question.
-
The purpose of the economy is not to maximize employment, but to utilize all the resources in the most efficient manner possible. If everyone knows their worth and employees know everything, unemployment shouldn’t exist (but it does because of imperfections, and lots of stuff that is highly debated).
-
The answer to the question completely misses what public vs private goods are. According to economic theory, it is NOT inefficient if we all vote to give up all possessions and live in trees! Similarly, if the electorate decides to vote for high taxes, and high public services, this is OK as well! Or, if they vote for no taxes, no defense, we’re ok with that!
I am sick and tired of non economists answering economic questions. I see it all the time in the media, and I still get lectured on macroeconomics from my father (who is wrong about everything).
One major misconception that EVERYONE seems to have:
Governments cannot go bankrupt, and can borrow every year!
As long as the debt to GDP ratio is stable or going down (and not skyrocketing up), governments can borrow money every single year. See Romer’s textbook for the explanation. The stable condition is that the total debt doesn’t increase more than the interest rate.
If governments do undergo unsustainable borrowing, they still will not go “bankrupt.” Bankrupt implies, sell of assets, no longer exist. Countries do not die like people, and don’t have to pay back all the money they ever borrowed (which is owed to private investors). Instead, what happens is like what is going on in Greece. Sure, it really sucks in the short term (and I don’t mean to gloss over how actual people are being financially hit). But in the long run, it won’t destroy the country. There are many countries that aren’t in Greece’s financial position and have much more serious problems that could result in death of a country (war, civil war, generally internal violence, and oh yeah war.)
I won’t touch the theories on Inequality that were ignored in this answer either. Kuznets is the source on this. Inequality has risen, but unlike other advanced countries we have lots of unskilled immigrants coming from Latin America (which I am for). There are several possible reasons that are missed here, so I will leave that to others.
