[M]y inquiring mind wants to know why Brad is worrying about “funding” tax cuts…. Here I only examine the notion that you must “pay for” tax cuts by either higher taxes or lower spending…. No analogy is perfect…. Economists often use a bathtub analogy to explain stocks and flows: water runs into the bathtub from the faucet (in-flow) that fills the tub (stock), so long as the water running out of the drain (out-flow) is less than the water running into the tub. If we plug the drain, the water stops running out—so the in-flow fills the tub. Brad wonders how do we “fund” the reduced outflow? I think that is a nonsensical question. Now, he might instead have wondered: what do we do when the tub is full? Would it then make sense to open the drain, or to slow the flow from the faucet? Sure. But how is that “funding” the previously reduced outflow during the period in which we closed the drain?My answer, IMHO, is that reducing the outflow--lowering tax collections--means that that date is closer at which the tub is full and we have to either open the drain (i.e., raise taxes) or slow the flow from the faucet (cut spending).
Makes no sense to me…. Tax cuts today cannot be “paid for” later by tax increases or spending reductions. There could come a time in the future when we decide that aggregate demand is too high--perhaps sparking inflation. At that time we might raise taxes, or cut spending, or stimulate more production, or use non-price rationing, or institute wage and price controls, or… who knows? But if and when we take those actions, they do not “pay for” today’s tax cuts…To this my response is: yes they do.
Brad DeLong is worried. And now I’m worried. He’s worried about “unfunded tax cuts,” which, he says, are “bad juju” in the long run. I don’t mean to pooh-pooh his juju, but what the heck is an “unfunded tax cut”?… Tax cuts leave taxpayers with more money to spend, but they don’t compromise the government’s ability to spend later. Nor is the debt ratio a binding constraint…. Can’t we just admit that the U.S. dollar comes from the U.S. government? That the i$$uer of the currency can never “run out” of money or be forced into bankruptcy…. Until people like us help awaken the population to the way modern money works, the deficit scolds will have the upper hand and the American people will suffer needlessly as Democrats and Republicans alike continue to hide behind the time-honored ”how will we pay for it?”As I understand it, Stephanie is going Abba Lerner--qualification (2) above. The hope is that the U.S. government can borrow and spend and that investors will always value U.S. government debt so highly as a safe store of value that, even without high inflation, the real interest rate on the debt will be on balance lower than the real growth rate of the American economy. If so, then the issuing of debt by the U.S. government is a very profitable business indeed: it makes something--safe nominal assets--that investors love and are willing to pay for through the nose, and we can finance whatever we want our government to spend on from the profits of this very profitable debt-issuing business.
