This research investigates whether a legal secondary concert ticket market, affects the prices on the primary market. Theory suggests that the prices in the primary market are higher when a legal secondary market exists. This research used a law change in Belgium in 2011, to check whether this was true. It does that by comparing the Belgium with the Dutch market, which did not have a law change. The outcome is interesting: the opposite seems true. When the secondary market is absent or illegal, the prices are not lower, but higher in the primary market.
