Simulation of the reference scenario in MULTIMOD suggests that GEMSU might produce an increase of long-term real interest rates equal to three fourths of 1 percent. An alternative tax policy that increases VAT by 2 percent leads to a similar path, with lower real interest rates but higher inflation. The simulation also suggests that the deutsche mark is likely to appreciate in real terms against other currencies as a result of GEMSU. Effects on other industrial countries will not be large, as the negative demand effects of higher interest rates and positive stimulus from higher imports of eastern Germany roughly offset.
