Abstract

The recent global financial crisis demonstrated that the simultaneous collapse of asset
bubbles in different countries is a major challenge for monetary policy. In order to eval-
uate determinants of these simultaneous asset bubbles, we detect rational asset bubbles
in corporate equity and real estate markets worldwide using forward recursive right-
sided ADF tests. Then we create dummy variables for simultaneous asset bubbles and
analyze potential determinants using gravity models and spatial economics. Our empir-
ical analysis suggests that simultaneous asset bubbles depend positively upon potential
asset demand, capital account openness, monetary conditions, cultural similarities and
negatively upon informational frictions and exchange rate flexibility. These findings im-
ply that monetary policy can impede the probability of simultaneous asset bubbles by
ensuring sound monetary conditions and choosing a flexible exchange regime.
