We develop a small open-economy trade model where either a tariff, or a quota, or a voluntary export restraint (VER) exists, and where one exported, one imported, one non-traded, and one public good are produced. Within this context we examine the effects of fiscal expansion on welfare and the real exchange rate (RER). Among other things, it is demonstrated that when the direct social profitability effect of the public good is positive and the public good is a net complement to the non-traded good, fiscal expansion causes an appreciation of the RER under free trade, and under a tariff when the public good is also a net complement to the imported good. The paper identifies additional conditions required to ensure the appreciation of the RER, due to fiscal expansion, under an import quota or a VER. Les effets de 1'expansion fiscale sur les taux de change reels quand il y a des restrictions au commerce international. Les auteurs developpent un modele de commerce international d'une petite economie ouverte oiu existe soit un tarif douanier, soit un contingentement, soit une restriction volontaire des exportations; dans ce modele un bien import6, un bien exporte, un bien qui n'est pas transige internationalement et un bien public sont produits.
