Tariffs and quotas are alternative trade instruments. In most cases it has been shown that the use of tariffs results in a higher national welfare than the use of quotas. Most of the research in this field has been purely theoretical. This paper aims to give an empirical contribution. Referring to the Norwegian apple market, we analyse the effects of tariffs and quotas. A tariff system is estimated to be slightly more efficient than a quota system (+ 2%). However, the distributional effects are substantial. Wholesalers and importers are main gainers in a quota system, while consumers and farmers are losers.
