We study a New Keynesian model where banks create deposits through loans, subject to increasing marginal cost of lending. Banks do not intermediate commodity deposits between savers and borrowers, instead they offer a payment system that intermediates ledger-entry deposits between spenders and...

We develop a New Keynesian model where all payments between agents require bank deposits through deposits-in-advance constraints, bank deposits are created through disbursement of bank loans, and banks face a convex lending cost. At the zero lower bound on deposit rates (ZLBD), changes in policy...
