With a seating capacity of 99,354 at present, Camp Nou is the largest association football stadium in Europe and the second largest in the world. It is the home stadium for, and owned by, Futbol Club Barcelona (FC Barcelona). Its seating capacity has changed over the years from 93,000 when it first opened in 1957 to over 115,000 in the early 1980s. In the 1990s, standing areas were converted to seats and the capacity reduced to its present level. Given that FC Barcelona sells out very few games per season, what economic reason might this monopolist have had to reduce its seating capacity?
