Protective tariffs are tariffs that are enacted with the aim of protecting a domestic industry.[1] They aim to make imported goods cost more than equivalent goods produced domestically, thereby causing sales of domestically produced goods to rise, supporting local industry. Tariffs are also imposed in order to raise government revenue, or to reduce an undesirable activity (sin tax). Although a tariff can simultaneously protect domestic industry and earn government revenue, the goals of protection and revenue maximization suggest different tariff rates, entailing a tradeoff between the two aims.
