Investor borrowing heterogeneity in a Kiyotaki-Moore style macro model

We allow for heterogeneity in investors' ability to borrow from collateral in a Kiyotaki-Moore style macro model. We calibrate the model to match the quintiles of the distribution of leverage ratios of US non-financial firms. We show that financial amplification of the model with heterogeneous investors can be orders of magnitude higher, because of more pronounced asset price reactions.
