We investigate the essentiality of credit and banking in a microfounded monetary model in which agents face heterogeneous idiosyncratic time preference shocks. Three main results arise from our analysis. First, the constrained-efficient allocation is unattainable without banks. Second, financial...

In monetary models in which agents are subject to trading shocks there is typically an ex-post inefficiency in that some agents are holding idle balances while others are cash constrained. This inefficiency creates a role for financial intermediaries, such as banks, who accept nominal deposits...

I calibrate the microfounded model in Boel and Camera (2009) to quantify the redistributive effects of inflation for a sample of OECD countries. In doing so, I address two important quantitative issues. First, using harmonized microdata from the Luxembourg Wealth Study, I provide an...

We construct a monetary economy with heterogeneity in discounting and consumption risk. Agents can insure against this risk with money and nominal government bonds, but all trades must be monetary. We demonstrate that a deflationary policy à la Friedman cannot sustain the constrained efficient...
