Credit booms are not rare and usually precede financial crises. However, some end in a crisis (bad booms) while others do not (good booms). We document that credit booms start with an increase in productivity, which subsequently falls much faster during bad booms. We develop a model in which...

In fighting a financial crisis, opacity (keeping the names of banks borrowing at emergency lending facilities secret) and stigma (the cost of having a bank's name revealed) are desirable to restore confidence. Lending facilities raise the perceived average quality of all banks' assets. Opacity...

We show that political booms, measured by the rise in governments' popularity, predict financial crises above and beyond other better-known early warning indicators, such as credit booms. This predictive power, however, only holds in emerging economies. We show that governments in emerging...
