Will asset price bubbles end up bursting “exogenously” or “endogenously”?

Once risk aversion subsides, the highly expansionary monetary policies being conducted today will in all likelihood lead to even more impressive asset price bubbles (valuation of equities and companies , real estate prices) than those observed in the past. This raises the question of what can cause bubbles to burst. A distinction can be drawn between: Bubbles that burst “exogenously”, due to a rise in interest rates, as was the case at the start of the subprime crisis in 2007-2008 with real estate prices; Bubbles that burst “endogenously” in the absence of a rise in interest rates, because asset prices become so high relative to income that demand for these assets collapses. This was the case in 1990 in Japan and in 2000 with new technology shares. Central banks’ new strategies (to drive down unemployment to a very low level, average inflation targeting) tend to point in favour of the scenario of endogenous bursting, which suggests that asset price bubbles will inflate hugely and for a long time.
