Tests for long-run purchasing power parity (PPP) may lack power with sample periods corresponding to the span of the recent float, leading researchers to use more powerful multivariate unit root tests. We point out a potential problem with such tests: joint non-stationarity of real exchange...

This paper addresses the issue of forecasting the term structure. We provide a unified state-space modelling framework that encompasses different existing discrete-time yield curve models. Within such framework we analyze the impact on forecasting performance of two crucial modelling choices,...

We show how to model portfolio models in the presence of long bonds. Specifically we study optimal fiscal policy under incomplete markets where the government issues bonds of maturity N 1. Assuming the existence of long bonds introduces an additional intertemporal mechanism that makes taxes...

This Paper examines how public debt, government credibility and external circumstances affect the probability of exchange rate devaluations in a three-period open-economy version of the Barro-Gordon (1983) model with nominal public debt. Public debt creates a link between current and future...

This paper brings together two strands of the empirical macro literature: the reduced-form evidence that the yield spread helps in forecasting output and the structural evidence on the difficulties of estimating the effect of monetary policy on output in an intertemporal Euler equation. We show...

We use a quantitative model of the US economy to analyse the response of long-term interest rates to monetary policy, and compare the model results with empirical evidence. We find that the model can explain the strong and time-varying yield curve response to monetary policy innovations found in...

Recent research suggests that commonly estimated dynamic Taylor rules augmented with a lagged interest rate imply too much predictability of interest rate changes compared with yield curve evidence. We show that this is not sufficient proof against the Taylor rule: the result could be driven by...
