In this paper we examine the role of nonlinearities in the relationship between nominal interest rates and inflation, in order to shed some additional light on the mostly unfavorable evidence on the presence of a full Fisher effect. The analysis is applied to the case of Spain for the period...

Traditional Phillips curves relating inflation to a measure of the level of activity, and augmented to include past inflation (assumed to proxy expected inflation), have been thought to be highly unstable over time. In this paper we try to investigate, using recent econometric developments,...

In this paper we provide an empirical test of the Fisher effect using cointegration techniques, where the existence of instabilities in the cointegrating or long-run relationships is explicitly tested. The analysis was applied to the UK, a country that has been subject to potentially stronger...

In this paper we re-examine the long-run sustainability of budget deficits, when fiscal policy is conducted as a nonlinear process. Our empirical methodology makes use of recent developments on threshold cointegration that consider the possibility of a nonlinear relationship between government...

In this paper we use recent developments on threshold autoregressive (TAR) models that allow us to derive endogenously threshold effects in the evolution of the Spanish budget deficit. Specifically, a mean-reverting dynamic behaviour of the budget deficit should be expected once such threshold...
