SHAKE the ketchup from the bottle/first, a little, then a lottle. We've all struggled to deal with Heinz's best known variety. And the pseudoplastic nature of the sauce helps explain why quantitative easing could, if things go wrong, end up in hyperinflation.ãAs Tim Lee of pi Economics suggests
The ketchup theory of inflation - Inflation and sovereign debtThe central bank keeps "shaking the bottle" (ie monetising debt) but no ketchup (ie inflation) comes out - so it shakes even harder. In the end, the ketchup comes out in an inflationary rush.

...I'm a believer in the ketchup theory of monetary policy. When central banks gradually tighten policy by raising the official interest rate, the dampening effect on demand isn't linear.
Ketchup theory will slow economy sharply
For a long time it looks like what you're doing is having no effect - and then one day the dam bursts. You shake and shake the ketchup bottle, none'll come and then a lot'll.
Why does it work like that? Because when you're battling to cool a boom, you're fighting what's politely called "business and consumer confidence", but which Keynes much more revealingly referred to as animal spirits.
And with animal spirits, they're either up or they're down, they're on or they're off. I've seen enough signs in the indicators to convince me the public has switched from go to whoa.ï¼æè¨³ï¼

This search for yield can be the rational response of a financial firm that knows that without higher yields, it will surely be unable to meet its obligation. It can be the quasi-rational response of a household that knows that at the prevailing low rates it will be unable to ever build its nest egg to desired levels unless it takes more risk. Thus it is possible that households and financial firms shift into riskier assets, boosting asset prices, and seeding asset price booms. Much of this shift can be non-linear, increasing substantially as interest rates fall below levels households and financial firms feel they can tolerate.
