We propose an extended time-varying parameter Vector Autoregression that allows for an evolving relationship between the variances of the shocks. Using this model, we show that the relationship between the conditional variance of GDP growth and the long-term interest rate has become weaker over...

This paper employs Threshold (T)VAR models to investigate the asymmetric impact of oil supply news shocks, analysing variations in both the size and direction of the shocks. Our findings reveal that large and adverse oil shocks exert a stronger effect on real activity, labour market indicators,...

Long-term interest rates in a number of small open inflation-targeting economies co-move more strongly with US long-term rates than with short-term rates in those economies. We augment a standard small open economy model with imperfectly substitutable government bonds and time-varying term...

Using a dynamic factor model, we uncover four main empirical regularities on international comovements in a long-run panel of real and nominal variables. First, the contribution of world comovements to domestic output growth has decreased over the post-WWII period. The contribution of regional...

We build a dynamic factor model with time-varying parameters and stochastic volatility and use it to decompose the variance of a large set of financial and macroeconomic variables for 22 OECD countries spanning from 1960 onwards into contributions from country-specific uncertainty,...

We study alternative approaches to the withdrawal of prolonged unconventional monetary stimulus ("exit strategies") by central banks in large, advanced economies. We first show empirically that large-scale asset purchases affect the exchange rate and domestic and foreign term premiums more...
