This paper inquires into the effect of choice of protection means, tariffs or quotas, on the economy's protection level for a small country within a specific-factor model when the protection level is determined by the lobbying activities by each industry (non-cooperative game) or jointly by negotiations of all the industries concerned (cooperative game). We will see that strategic interaction among lobbying industries gives rise to non-equivalence between tariffs and quotas.
