Macroprudential Policy in the New Keynesian World

We integrate banks and the coexistence of bank and bond financing into an otherwise standard New Keynesian Framework with capital, and derive the microfounded, bank-augmented IS and Phillips Curves for the corresponding two-sector economy. We study the interplay of monetary and macroprudential policies. We examine how policy-making could be operationalized by loss functions for monetary and macroprudential policy-making. Finally, we investigate the optimal institutional structures.
