Unfortunately Keynesians don't have any intuition for this, because everything's all just 'aggregate demand', not housing, technology, energy, etc. Aggregation leads to simplifcation, but clearly it has a cost, and I think any macro theory that ignores the fact that an economy is a network of firms and individuals is pointless.
Hayek's early work on business cycles focused on misalignments in the structure of production. Alas, this was basically impossible to formalize. Keyenes's model, meanwhile, was adopted into the Hansen-Hicks synthesis that looked a lot like the simple Supply/Demand equations economists were used to, so everything seemed copacetic. A bad idea, in a tractable model, has a long life, because everyone forgets about all the hand waiving assumptions that underlie such models.
There's more, and Falkenstein is even partial to Wenzel's patented "Bottom line:" summary finishing move.
