This paper exploits the result that in the case of I(2) processes the precise dating of variables is crucial when empirically testing for cointegration. The data for the latter part of the German hyperinflation episode exhibit I(2) behaviour. We utilize these data to discriminate between...

[fre] Ajustement non linéaire vers le taux de change d'équilibre à long terme. Le modèle monétaire revisité. . Nous réexaminons la famille des modèles monétaires à travers l'examen d'un ajustement non linéaire vers un modèle monétaire d'équilibre à long terme. En uti­lisant des...

This paper considers optimal monetary policy in the context of the central bank adopting an asymmetric objective function. Our results show that under asymmetric preferences, many of the extant results on the time consistency problem need no longer hold. Copyright 2003 Royal Economic Society.

A stylized fact of US inflation dynamics is one of extreme persistence and possible unit root behavior. If so, the implications for macroeconomics and monetary policy are somewhat unpalatable. Our econometric analysis proposes a parsimonious representation of the inflation process, the nonlinear...

This paper considers optimal monetary in the context of the central bank adopting a asymmetric objective function. We exploit a procedure, due to Varian and Zellner, to derive policies under commitment and discretion. Our results show that under asymmetric preferences, many of the extant results...

Equilibrium models of real exchange rate determination in the presence of transactions costs imply a nonlinear adjustment process toward purchasing power parity (PPP). Conventional cointegration tests, which ignore the effect of transactions costs, may be biased against the long-run PPP...
