We propose a model where monetary policy is the key determinant of aggregate asset prices (financial conditions). Spending decisions are made by a group of agents ("households") that respond to aggregate asset prices, but with noise, delays, and inertia. Asset pricing is determined by a...

This article summarizes empirical research on the interaction between monetary policy and asset markets, and reviews our previous theoretical work that captures these interactions. We present a concise model in which monetary policy impacts the aggregate asset price, which in turn influences...

Do periods of persistently loose monetary policy increase financial fragility and the likelihood of a financial crisis? This is a central question for policymakers, yet the literature does not provide systematic empirical evidence about this link at the aggregate level. In this paper we fill...

An impulse response is the dynamic average effect of an intervention across horizons. We use the well-known Kitagawa-Blinder-Oaxaca decomposition to explore a response's heterogeneity over time and over states of the economy. This can be implemented with a simple extension to the usual local...
