This paper develops a dual-state monetary DSGE model that accommodates refined financial accelerator to analyze UK policy. Unconventional policy (QE) is interpreted as expanding the central bank’s purchases of bonds using M0 offset disruptions at ZLB. Within collateral-augmented costly state verification framework, enters cheapest collateral and reduces cost credit. The tested estimated indirec...

I n an open macroeconomy, in which asset trade is possible, the portfolio choice of households may play an important role in understanding macro fluctuations. In contrast to a closed economy model, in which a representative agent simply holds the market portfolio, agents in each country may hold different portfolios depending on the country-specific risks and returns that they encounter. Robert...

Epstein-Zin preferences (or “EZ” preferences) have become increasingly popular in recent asset pricing work. Dynamic stochastic general equilibrium (DSGE) models which feature Epstein-Zin preferences are typically considered technically challenging, often thought to require sophisticated numerical solution methods to solve them and considerable additional thought to understand them. The purpose...

The past forty years or so has seen a remarkable transformation in macro-models used by central banks, policymakers and forecasting bodies. This papers describes this transformation from reduced-form behavioural equations estimated separately, through to contemporary micro-founded dynamic stochastic general equilibrium (DSGE) models estimated by systems methods. In particular by treating DSGE m...

Tractable Latent State Filtering for Non-Linear DSGE Models Using a Second-Order Approximation* This paper develops a novel approach for estimating latent state variables of Dynamic Stochastic General Equilibrium (DSGE) models that are solved using a second-order accurate approximation. I apply the Kalman filter to a statespace representation of the second-order solution based on the ‘pruning’ ...
