Financial market interactions can lead to large and persistent booms and recessions. Instability is an inherent threat to economies with speculative financial markets. A central bank's interest rate setting can amplify the expectation feedback in the financial market and this can lead to...

Using a parsimonious, analytically tractable dynamic model, we are able to explain up to 100 years of the available data on the dynamics of top-wealth shares for several countries. We build a micro-founded model of heterogeneous agents in which - in addition to stochastic returns on investment -...

We use nonlinear Bayesian methods to evaluate the performance of financial frictions á la Bernanke et al. (1999) during and after the Global Financial Crisis. We find that, despite the attention received in the literature, including these frictions in the canonical medium-scale DSGE model does...

Building on automatic differentiation, I propose a solution method for heterogeneous agents models with many aggregate equations which allows to account even for strong nonlinearities. A powerful open source reference implementation is provided which typically solves the canonical HANK model...
