The recent success of fast fashion retailers has changed the (affordable) fashion industry dramatically. These companies, such as Zara, are characterized by a flexible supply chain that has allowed them to reduce design and production lead times to just a few weeks, rather than months. More importantly, they are using these capabilities to change the assortment (i.e., introduce new products) more frequently, which many practitioners claim increases sales, since there is evidence showing that customers visit more often the stores with fresher products. We propose in this chapter a customer consumption model with satiation and multiple competing retailers. The model implies that the consumers will spend a higher share of their budget in retailers that renovate the assortment at a faster pace. Using the insights from the model, we determine how often retailers should change the assortment in the competitive equilibrium.
