In this note, we suggest a link between tariff protection and firms' incentives to engage in a horizontal merger. We consider a Cournot oligopoly with equal, constant marginal costs where firms have to decide on lobbying efforts prior to choosing output. These lobbying efforts will determine whether a prohibitive tariff is introduced. We find that the possibility of lobbying may enlarge the set of mergers that are profitable, even without cost reductions.
