Monetary policy and asset price bubbles

The appropriate monetary policy response to an asset price bubble remains unclear and is one of the most contentious issues currently facing central banks. Some have argued that monetary policy should be used to contain or reduce an asset price bubble in order to alleviate its adverse consequences on the economy, while others have argued that such a policy would be both impractical and unproductive given real-world uncertainties about the nature or even existence of bubbles. This Economic Letter examines how policymakers might choose between alternative courses of action when confronted with a possible asset price bubble.
