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.

The paper uses the P-STAR model to analyze Spanish prices from 1970 to 1996, adding the foreign price gap to the standard domestic definition of the P-STAR model (the domestic price gap) to assess the role German price movements played in Spanish inflation. The domestic price gap turns out to be the major explanatory variable for inflation, even after the entrance of Spain in the exchange rate mechanism (ERM). This result suggests that the successful disinflation experienced in Spain in the past few years may be more related to domestic conditions than to foreign ones.

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.
