Both channels derive from a failure of the Modigliani-Miller theorem for banks.

The first set illustrates the Modigliani-Miller Theorem.
This invariance of the value of the firm to its financing decision is an example of the Modigliani-Miller theorem (Modigliani and Miller 1958).
Miller often expounds jokingly the Modigliani-Miller theorem
by saying "you may understand it if you know why this is a joke.
The second equality in (10) follows by (8) and provides a familiar corollary to the 1958 Modigliani-Miller theorem
(Modigliani and Miller, 1958); for examples in the literature see MacMinn (1987).
