    Review of Economic Studies

We use experiments to examine whether the auctioning of entry rights affects the behaviour of market entrants. Standard economic arguments suggest that the licence fee paid at the auction will not affect pricing since it constitutes a sunk cost. This argument is not uncontested though, and this paper puts it to an experimental test. Our results indicate that an auction of entry licences has a significant positive effect on average prices in oligopoly but not in monopoly. These results are consistent with the conjecture that entry fees induce players to take more risk in pursuit of higher expected profits. In oligopoly, entry fees increase the probability that the market entrants coordinate on a collusive price path. In monopoly, taking more risk does not make sense since average prices are already close to the profit-maximizing price.
