Should monetary policy have a prudential dimension? That is, should policymakers raise interest rates to rein in financial excesses during a boom? We theoretically investigate this issue using an aggregate demand model with asset price booms and financial speculation. In our model, monetary...

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...

We analyze optimal monetary policy and its implications for asset prices, when aggregate demand has inertia and responds to asset prices with a lag. If there is a negative output gap, the central bank optimally overshoots aggregate asset prices (asset prices are initially pushed above their...
