Sustainability tests often ignore the joint dynamics of stock and flow variables. This paper shows that such a practice leads to inappropriate statistical inference, and that taking into account this joint dynamics when testing for unit root induces large power gains. This paper introduces a new...

This paper introduces a new unit root test, using "Feedback Covariates", in order to test for sustainability of fiscal policy within the G-7.Non-sustainability is considered as the null hypothesis of both a unit root in the debt process and the nullity of a deficit correction in response to...

This paper proposes a new testing strategy for unemployment hysteris as the joint restriction of a unit-root in the unemployment rate and no-effect of the level of unemployment in the Phillips wage equation. The relevant test statistics are derived when this joint restriction is imposed during...

Recent studies have highlighted the existence of asymmetries in employment dynamics. This paper contributes to the analysis of this dynamics through the explicit modelling of its two components -job creations and job destructions. We propose a simple matching model extended for endogenous...
