Deflation means a complete mental rethink and is beyond the understanding of most people today who were raised in inflationary times. The real question is an emotional one: how will ordinary people behave if they think prices are going to fall year on year for more than a very short period?
What happens in deflation?
When prices fall, the value of cash rises. Anyone with money has an advantage, and those with debts lose. If I have a mortgage of $250,000 this year, and deflation runs at 5% a year, it means in real terms my loan will double in size over 15 years. Most worryingly, in deflation, my loan (which was only 70% of the value of my home) will become so huge that even if I sell my home, I will be left with large debts.
We have all seen deflation before in one key area: computers and digital technology where deflation has been eating away at price levels for three decades or more. But this is different. It is one thing to write off an investment in a computer system over three years, but another to find that one of your greatest assets, your own home, is worth only a small fraction of what it was twenty years ago, and that prices of every other asset you own are also expected to go on falling.
Of course, if you have cash in hand, the temptation is to spend nothing and invest in nothing. What is the point of buying when you know that in six months' time the chances are you could buy more? So money gets left as cash under the bed, or in a bank account (if you are prepared to risk the bank going bust because so many loans were secured against assets, now worth almost nothing). Spending falls, feeding a further frenzy of price cutting, downward pressure on salaries, bonus cutting, and so on. But it is easier to pay people less and get away with it when they know they need less to live on this year than last year.
Interest rates fall to zero because no one in their right minds wants to borrow large amounts of an asset (cash) which is going to inflate with time. Indeed, the only asset for ordinary men and women that grows in value in a deflationary economy is cash, and cash is what you find they hang on to. Just look at Japan which has experienced deflation for years with terrible consequences.
How serious is the risk of deflation hitting other economies?
