We study the role of nonlinear simple rules for monetary policy. We depart from the standard rules proposed by Taylor (1993), and consider a nonlinear rule for the so-called opportunistic approach to disinflation originally proposed by Orphanides and Wilcox (2002) and Aksoy, Orphanides, Small,...

The proponents of the 'opportunistic' approach to disinflation suggest that, when inflation is close to the target, the central bank should not counteract inflationary pressures. Orphanides and Wilcox (2002) formalize this idea through a simple policy rule that prescribes a nonlinear adjustment...

We investigate how the relation between gold prices and the U.S. Dollar has been affected by the recent turmoil in financial markets. We use spot prices of gold and spot bilateral exchange rates against the Euro and the British Pound to study the pattern of volatility spillovers. We estimate the...

This paper highlights the analysis of the term structure of interest rate within a full DSGE model. Our goal consists in setting up a full model including the feed-back from the economy to the term structure and vice-versa. Contrary to existing models of the term structure (TS, henceforth) (for...

This note reconsiders the impact of the reform of the operational framework of the European Central Bank that took place in March 2004. We estimate a bivariate GARCH model with the overnight rate and 1-year swap rate, where identifying restrictions are imposed on the conditional variance....

We study the joint movements of the returns on futures for crude oil, heating oil and natural gas at a daily frequency. We model the leptokurtic behavior through the multivariate GARCH with dynamic conditional correlations and elliptical distributions introduced by Pelagatti and Rondena (2004)....

We study the pattern of contagion in volatility along the term structure of oil forwards. We use measures of codependence of returns from quantile regressions to discriminate between integration of the markets for different maturities in the cases of low and high volatility of the returns. Our...

The present paper compares the performance in terms of second order accurate welfare of opportunistic non-linear Taylor rules and with respect to traditional linear Taylor rules. The macroeconomic model representing the benchmark for the analysis includes capital accumulation (with quadratic...
