This paper studies the impact of inventory-intensity, marketing-intensity and firm size on the markups of exporting firms. We used audited financial statement data of publicly listed companies in the spinning, weaving and finishing industry within the textiles sector of Pakistan. We document five observations: 1) average markup of exporters is relatively higher than non-exporters; 2) there is higher dispersion in markups of non-exporters relative to exporters; 3) large firms have relatively higher markup and marketing-intensity; 4) firms which have higher marketing- and inventory-intensity also have higher markups; and 5) exporters have relatively higher markup elasticity with respect to marketing-intensity, inventory-intensity and growth in inventory-intensity.
