Loanable funds versus money creation in banking: a benchmark result

Abstract We establish a benchmark result for the relationship between the loanable-funds and the money-creation approach to banking. In particular, we show that both processes yield the same allocations when there is no uncertainty. In such cases, using the much simpler loanable-funds approach as a shortcut does not imply any loss of generality.

When there is aggregate risk with complete contracts and complete markets, we indicate that a restricted equivalence result holds.
