This paper investigates the pricing-to-market (PTM) behaviour of Italian exporting firms, using quarterly survey data by sector and by region over the period 1999q1-2005q2. A partial equilibrium imperfect competition model provides the structure according to which the orthogonality of structural shocks is derived. Impulse-response analysis shows non-negligible reactions of export-domestic price margins to unanticipated changes in cost competitiveness and in foreign and domestic demand levels, even though these effects appear to be of a transitory nature. For the period 1999-2001 a typical PTM behaviour emerges, while during the most recent years favourable foreign demand conditions allowed firms to increase their export-domestic price margins in face of a strong deterioration of their cost competitiveness. Macroeconomic implications of the observed PTM behaviour are also discussed.
