linkSo, to quote
Nephos, who linked to a very pretty
pictureAn interesting example is looking at US inflation around WW1: Inflation skyrocketed at the end of the war as the US invested in sending its work force toward futile engagement in the trenches. And then deflation skyrocketed once they came home. The average over this period was probably somewhere in the vicinity of something small.
Using the linked table -- and there's a line between quoting and stealing I'm never sure when I cross, but I make you click in to
the table -- inflation in the year 1924 was zero, so we'll treat that as a turning point (even though the year before was positive, at 1.8%) and end in 1923. Inflation jumps from 1% in 1914 and 1915 to 7.9% in 1916, so we'll start in 1916. This gives us inflation rates of 7.9, 17.4, 18, 14.6, 15.6, -10.5, -6.1 and 1.8 per cent per year, which add up to a 1915 dollar being worth 93 cents at the end of 1916 and 59 cents at the end of 1923. Deflation starts in again about half-way through 1926 -- remember that's supposed to be the middle of a great economic boom -- so the 1915 dollar bottoms out at 58 cents in 1926 before zooming back up to 78 cents (nearly its 1917 value) after 1933. In 1943, it's back to 58 cents.
Look, I made a plot.
The four post WWI years 1930 - 1933 had a lot of deflation, and it took ten years to undo them. Using this as a precedent, buying a house could still be an extremely sucky investment. However, I think the path of inflation will be the one we'll follow.
