With this projects, the students wanted to confirm that traditional commerce was losing market share due to international brand stores and new forms of small convenience stores. For this, they used data related to the surface of the cadastral premises in Barcelona city.

• The third prize went to the Institut Joan Brossa and his "On locate the meva botiga to Barcelona?" (Where to locate my store in Barcelona?). The analysis was based on the comparison of the Commercial Endowment Index and the Commercial Attraction Index.
