Recently, Vogelsang (1999) proposed a method to detect outliers which explicitly imposes the null hypothesis of a unit root. It works in an iterative fashion to select multiple outliers in a given series. We show, via simulations, that under the null hypothesis of no outliers, it has the right...

We propose residual based tests for cointegration using local GLS detrending (Elliott, Rothemberg and Stock (1996), ERS) to eliminate separately the deterministic components in the series. We consider two cases, one where only a constant is included and one where a constant and a time trend are...

This paper proposes a theoretical framework to analyze the relationship between credit shocks, firm defaults and volatility, and to study the impact of credit shocks on business cycle dynamics. Firms are identical ex ante but differ ex post due to different realizations of firm-specific...
