Asset Bubbles: Detecting and Measuring Them Are Not Easy Tasks
Market bubbles are linked to many historic financial crises, but asset price run-ups can reflect both fundamental value changes and psychological contagion. Using historic values of commonly held assets (stocks and real estate), a novel ?exuberance index? offers a way to compare bubbles.

The Roots of ‘Bubbly’ Recessions

It argues, based on insights from a simple economic model, that the interaction among financial frictions, wage rigidity, and the constraints of monetary policy near the zero lower bound is a key source of inefficiency in large bubbles. One potential remedy is to regulate speculative investment on bubbly assets so that ...
On Interest Rate Policy and Asset Bubbles
In a provocative paper, Gal (2014) showed that a policymaker who raises interest rates to rein in a potential bubble will only make a bubble bigger if one exists. This poses a challenge to advocates of lean-against-the-wind policies that call for raising interest rates to mitigate potential bubbles. In this paper, we argue there are situations in which the lean-against-the wind view is justified.

Once we modify Gal?s ...
