This is typical business cycle theory which I disagree with on multiple levels. I'd
be happy to start a separate thread on this discussion if you're game. I reject the business cycle as a Minskyite.
Secondly, if the dollar is replaced as a reserve currency, the impact will have a negligible effect on our lives.Literally.
Capital is not immune from the laws of supply and demand. If priced improperly, it will create distortions and dislocations. We've had two massive bubbles over the past 15 years because of this.
And when I mean "replace the dollar," I mean we, the United States, use another American currency, the dollar 2.0 or whatever. Most currencies that existed 150 years ago aren't in existence today. Currencies exist only because the people have confidence in it. If Americans lose confidence in the dollar, it would cease being a functional currency. Pinning the funds rate at zero forever would increase the odds of an internal dollar collapse immensely.
I've heard this argument a lot and frankly it makes no sense (literally) to me. Why are low rates of interest more likely than high rates to produce inefficiency and misallocation? When interest rates were 22%, did we have a superior allocation of capital?
I get that easy LENDING promotes bubbles and possible misallocation of capital, but with small businesses starved for capital while banks sit on trillions of excess reserves, I don't see a connection. We have a simultaneous capital shortage in our most productive sector and a capital glut in the financial sector; probably the biggest misallocation of capital in modern history.
There's a difference between
cyclical and
secular. Excess reserves today are a cyclical issue. Pegging interest rates at 0% until the end of time - as the OP argues - is a secular issue.
I think that the Fed is creating and contributing to serial asset bubbles with its policies over the past 15 or maybe 25 years, beginning perhaps with the 1987 bailout of the market crash but certainly with the bailout of the market after the LTCM debacle. It is my belief that the Fed's current policy will end badly. However, I may be dead wrong. History may prove that the Bernank is totally right. Stocks going up and gold going down may be the market telling us that everything will be fine. I have to respect the market, and I have enough experience in capital markets to know that I am very fallible.
As for the 22% interest rates, I think Alfred Marshall's theory of capital formation is correct. Over time, the rate of return on the capital stock of the company should equal the long term growth rate of the economy. Marshall argued that over time, the capital stock should grow at the same rate of the economy, and the cost of capital was the opportunity cost of investing within the economy. Thus, the real weighted average cost of capital should equal the rate of return of the economy over time.
That makes sense. If the real long-term growth of the economy is 2%, if real returns are greater than 2%, eventually, the growth in the capital stock will subsume the entire economy, which is mathematically impossible. At some point, if the growth of the capital stock exceeds the growth in the economy, there will be excess productive capacity, which will lower returns on capital and eventually destroy the least marginally profitable plant. That's what happened during the Tech Bubble, and what happened during the Housing Bubble.
However, that may not hold over the short-term as cyclical fluctuations vary with variations in supply and demand, particularly when non-market agents, i.e. the Fed, influence the rate of interest. Inflation distorts capital allocation and channels capital into non-productive activities. When inflation is high, the non-market agent, i.e. the Fed, may decide to keep interest rates high to lower inflation. Thus, from year to year, interest rates may be above (or below) the long-term growth rate of the economy. But over time, interest rates within the total weighted cost of capital should normalize to the growth rate of the economy.
