This note examines interest rate linkages within the EMS. Cointegration tests suggest the existence of a long-run equilibrium relationship between German and other EMS interest rates. Bivariate VAR analysis finds that Granger-causality either stems from German to other European interest rates (Belgium, France, Spain, and the U.K.) or is bidirectional (Denmark and the Netherlands). When allowance is made for the influence of U.S. interest rates, the pattern of Granger causality is predominantly bidirectional.
This paper investigates, using cointegration and Granger-causality techniques, whether a stable long-run co-movement exists between world commodity prices and U.K. retail prices, and whether short-run changes in commodity prices convey information about future movements in U.K. retail prices. The results show noncointegration and no unidirectional Granger causality from commodity to retail prices. These findings suggest that little may be gained from using developments in commodity prices to forecast movements in retail prices in the inflation-targeting framework followed by the U.K. monetary authorities.
