In Norway house prices have risen to high levels, associated with very strong credit growth, in a context of low interest rates. Such a combination was in many countries a contributory factor to the 2008- 09 crisis. The Norwegian authorities have been well aware of the problem. Below-target...

We explore empirically how capital inflows into the US and financial deregulation within the United States interacted in driving the run-up (and subsequent decline) in US housing prices over the period 1990-2010. To obtain an ex ante measure of financial liberalization, we focus on the history...

The Danish financial sector is big and there is a high degree of inter-connectedness between banks, mortgage institutions and pension funds. Danish households have large balance sheets and high levels of gross debt. Even though the high debt levels are matched by large assets, notably in form of...

We study information acquisition and dynamic withdrawal decisions when a spreading rumor exposes a solvent bank to a run. Uncertainty about the bank's liquidity and potential failure motivates depositors who hear the rumor to acquire additional noisy signals. Depositors with less informative...

Should policy makers be permitted to intervene during a financial crisis by bailing out financial institutions and their investors? We study this question in a model that incorporates two competing views about the underlying causes of these crises: self-fulfilling shifts in investors'...
