Well, I think there is a fair amount of empirical evidence that suggests that there is a stall speed for the economy. One interesting fact from the post war-- World War II period in the United States is we've never had a three-tenths of a percent rise in the unemployment rate without actually once it goes up three-tenths of a percent, we end up having a full blown recession.
And the next-- increase after three-tenths of a percent, the smallest is 1.9 percentage points. So that we've never had an increase in the unemployment rate of just a half a percent, or just one percent, or just one and a half percent. So that does suggest that that-- that once you get to a certain point, and an unemployment rate goes up enough, that starts to weigh on confidence, that starts to weigh on spending. If spending is cut back, that leads to more unemployment, and the economy cycles down into recession.
