Willem Buiter considers various ways to make interest rates negative. The problem is how to pay negative interest rates on currency. His most interesting proposal is to separate the unit of account from the currency. The dollar would remain the unit of account (at least, he hopes it will). But he would replace dollar notes and coins with a new currency, the "rallod", which would depreciate against the dollar. If it depreciated at (say) 5% per year, it would allow nominal interest rates on dollars to go down as low as minus 5%, which should be sufficient to get us out of the recession.
It seems a very complicated proposal, when you read it. It certainly fails my "Grandmother" test. (Grandma could never understand Britain's new decimal currency, and the switch from shillings and old pennies to new pennies, so refused to deal in anything smaller than the pound, which stayed the same.)
So I decided it needed to be simplified.
My first idea, rather than changing the currency, was to change the other units of measurement. After all, we buy apples in kilograms, milk in litres, labour by the hour, etc., so why not just redefine the kilogram, litre, and hour so that they got 5% smaller per year? So even if the price of apples in dollars per kilogram stayed the same, at the end of the year we would get 5% fewer apples per unit of currency. Exactly the same as if the "rallod", were worth 5% less in terms of dollars.
But after careful consideration, and long consultations with colleagues in other departments, I decided that my idea would not make for good relations between economists and other scientists, who seem rather attached to their existing units of measurement. The engineers in particular seemed to suffer from "unit illusion", and couldn't adjust to a world of inflation. So I abandoned my first idea, and returned to thinking about Willem's proposal.
How to simplify Willem's proposal for the "rallod"?
Well, the name "rallod" has to go for starters. It's ugly, and sounds far too radical. The common convention for currency reforms is to introduce a new currency, and call it the "New...." whatever the old currency was. The "New Franc" replaced the old Franc in France. So let's just call it the "New Dollar". And to be doubly sure there is no misunderstanding, we can refer to the old dollar as the "Old Dollar".
And it would be a major hassle and expense to call in all the old dollar coins and bills and print up new dollars to replace them. It would be much simpler for the government and central bank to just make a declaration: "Henceforth, all existing dollar notes and coins are now declared to be New Dollar notes and coins!". One problem solved!
Now, since the New Dollar will be depreciating at 5% per year against the old dollar, and all existing contracts are denominated in old dollars, we will have to remind people that the number of New Dollar notes they will need to pay to fulfill any existing contract (if they choose to pay with currency) will need to be increasing at the rate of 5% per year. That would apply to all debt contracts, wage contracts, price contracts, etc. And the courts would of course enforce that interpretation of the contracts. And there is nothing unjust about doing this, of course, because the New Dollars won't be worth as much as the old dollars.
Alternatively, and perhaps it would be simpler, we could just rewrite all the old contracts, add a 5% per year premium to any price, wage, or rate of interest, so that payment could be specified in New Dollars, if that's what people wanted to pay in.
Actually, now that I come to think of it, do we really need the ugly neologism "New Dollar"? Since we wanted to avoid the cost and hassle of printing new notes and coins, the notes and coins still say "dollar" rather than the "New Dollar". So, to avoid confusion, let's keep the word "Dollar" for the New Dollar. And use the words "Old Dollar" (or "Classic Dollar"?) for any contract written before the New Dollar...I mean the Dollar...was introduced.
Actually, now I think of it some more, isn't there only one thing we need to do? Just pass a law saying that all contracts written in dollars before a certain date must have an additional 5% per year premium written into them?
So a 4% mortgage would now become a 9% mortgage, by law. A contract specifying a 3% wage increase per year would now specify 8%, by law. And so on. And just to anchor inflation expectations to the new currency regime, to help people adjust, the central bank should announce that the inflation target will be raised from 2% to 7%, and that whatever inflation rate people had previously expected, in old dollars, should now be revised upwards by 5%.
So, to recap: raise all existing nominal interest rates by 5% per year; raise all existing wage and price contracts by 5% per year; raise the inflation target by 5% per year; and tell people to expect inflation to be higher by 5% per year. New interest rates and new wage and price contracts can be set wherever they need be, of course. That's my simplified version of Willem's proposal.
Why wouldn't my version work? Only the names are different.
I am for a Guaranteed Income with health care insurance, as put forward in Charles Murray's "In Our Hands". Is there a Canadian blog that advocates this? I have links to one in the US and one in the UK.
