A warm hat tip to Ed Marsh, Head of Economics at Glyn School for spotting this superb example of a sports club using dynamic pricing technology to determine the prices of tickets for their home games. The BBC news site reports that Derby County are introducing "demand-based" ticketing for the coming season with prices fluctuating according to the opposition, the team's form, kick-off times and even the weather. The system is known as Sports and Entertainment Analytical Ticketing System (SEATS) Buy in advance and fans will get cheaper prices - but what if a sizeable group decides to start a game of chicken with the club and hold back from buying? As match day gets closer, ticket prices should move higher, but if demand for a game is well below the stadium's capacity will prices drop back?Hardened cynics might also point out that the Derby County ground has a fundamental design flaw .... the seats face the pitch!
