In this paper we generalize the target zone exchange rate as model formalized by Krugman (1988b) to include finite-sized interventions in defense of the zone. The main contributions of these pages consist of linking the recent developments in the theory of target zones to the mirror-image theory of speculative attacks on asset price fixing regimes and in using aspects of that linkage to give an intuitive interpretation to the smooth pasting" condition usually invoked as a terminal condition.
