In several recent studies unit root methods have been used in detection of financial bubbles in asset prices. The basic idea is that fundamental changes in the autocorrelation structure of relevant time series imply the presence of a rational price bubble. We provide cross-country evidence for...

Equilibrium credit is an important concept because it helps identify excessive credit provision. This paper proposes a two-stage approach to determine equilibrium credit. It uses two stages to study changes in the demand for credit due to varying levels of economic, financial and institutional...

Forecasts play a critical role at inflation-targeting central banks, such as the Bank of England. Breaks in the forecast performance of a model can potentially incur important policy costs. Commonly used statistical procedures, however, implicitly put a lot of weight on type I errors (or false...
