Even when "everyone" is expecting a recession, most are still caught off-guard when it actually happens.
The reason?
Our poor appreciation for and understanding of nonlinearity.
"How did you go bankrupt?"
"Two ways, gradually, then suddenly."
This classic Ernest Hemmingway quote highlights the problem.
When manufacturing activity slows down, it does so in a nonlinear way.
When credit spreads widen, they do so in a nonlinear way.
When the unemployment rate rises, it does so in a nonlinear way.
And let's not forget the stock market - its downward spirals are anything but linear!
Unfortunately, the finance industry's most preferred forecasting method is straight-line extrapolation of the recent past. No wonder we are caught off-guard so often!
