What are desired savings?
Quote from: D1984 on April 04, 2013, 05:17:45 PM
But interest rates can only fall to zero so long as there is such a thing as physical money (when I say "physical money" I'm not even talking about gold...even physical paper money will do the trick) because no one will lend money out at a negative nominal rate when they can just sit in paper cash and earn 0%. What is supposed to happen when desired savings at any one time are greater than desired investment and you are still at the zero lower bound?
Please restate this. I think there is a real question dying to get out but it's cloaked in nonsense that I can't understand. I might be too dumb.
Maybe I should have been more explicit about what "desired savings" and "the zero lower bound" meant as I was describing them. My bad.
"Desired savings" is the amount of income that every economic player (invidividuals, corporations, households, small businesses, not-for-profits, etc) desires to save out of the amount that they earn. If total income (including profits, interest, dividends, wages, etc) in the economy is $10 trillion and people desire to save 10% of that, then desired savings is $1 trillion dollars.
Now, economic actors may choose to save or invest/consume a greater or lesser percentage of their income depending on what economic conditions they foresee in the future and on what rate of return they can currently get on savings. Sometimes the amount economic actors desire to save is greater than the amount desired for investment/consumption at any given rate. This normally wouldn't be a problem (with or without the Fed); as the amount of desired savings (the good supplied...in this case the amount of money as savings) increases and the demand for it (consumption and eventually investment) decreases, the laws of supply and demand will dictate that rates will fall--more supply of a good chasing less demand for it generally equals a lower price for the given good....the "price" for money is the interest rate charged to borrow it. As rates fall, more people/companies will choose to save less (because it is less rewarding as they earn less interest for doing so); conversely, borrowing to invest/consume will become more attractive as rates fall and thus it becomes less expensive to borrow. The actual interest rate at which desired savings is equal to the amount of desired borrowing for investment or consumption will vary over time but the situation is usually that it reaches an equilibrium at some given rate above zero.
The problem starts when you have something like a "Minsky moment" (and subsequent deleveraging shock) when everyone as a whole (i.e. at a macroeconomic level) on average decides that they need to save more and consume less. In such a situation, rates can fall even to zero percent and the amount of money people/companies desire to save (i.e. not use for present consumption or investment) may still be greater than the given demand for it (because almost everyone is trying to become net savers and proportionately fewer want to borrow to invest or consume unless absolutely necessary). The usual response of the market (and/or the Fed) is to lower rates so that borrowing to invest/consume becomes more attractive and sitting on money becomes less attractive.....but the fact is, rates cannot go below zero for any real length of time because no one would lend money at, say -3% or -8% because they can get a guaranteed 0% just by sitting in physical cash; why lose money lending it out when you can just put it in the sock drawer and earn nothing but lose nothing either? That is what the "zero lower bound" phenomenon is. Deflation can in many cases only make it worse as sitting on cash earning a
nominal 0% during a deflation means that one is actually earning a positive
real return even at 0% nominal so the incentive to consume/invest is lessened even further (after all, in such a case any investments/consumption you choose to defer to the future will be even cheaper as prices fall) and the incentive to save is increased when the economy is already awash with excess savings that can't even find a productive home because even at 0% not enough people/companies want to borrow for investment or consumption.
