This review discusses methods of testing for explosive bubbles in a time series. A large number of recently developed testing methods under various assumptions about innovations of the errors are covered. The review also considers the methods for dating the explosive (bubble) regimes. Special...

This paper is devoted to fiscal shock identification based on the assumption of nonGaussianity of the errors, which can be easily tested. We use additional co-kurtosis conditions in GMM estimation of the AB-model to estimate the dynamic effects of fiscal shocks and find fiscal multipliers in the...

In this paper we extend the stationarity test proposed by Kurozumi and Tanaka (2010) for reducing size distortion with one structural break. We fi nd the bias up to the order of 1=T for four types of models containing structural breaks. The simulations on finite samples show a reducing of size...
