1. The Effective Rate of Protection The Effective Rate of Protection measures the percentage effect of the entire tariff structure on the value added per unit of output in each industry.

2. The Effective Rate of Protection t Tariff Structure Tariff structure refers to the relationship among tariffs in related industries. t Value Added Value added is the difference between the selling price and the cost of intermediate goods. V = P A - P S a

3. The Effective Rate of Protection ERP = ( V’- V ) / V t ERP = Effective Rate of Protection t V’ = Value Added with tariff t V = Value added with free trade

4. The Effective Rate of Protection ERP = (t f – at i ) / (1 – a) Where t f is the nominal tariff on the imported finished good, a is the value of imported inputs as a share of the value of the final good under free trade, and t i is the tariff on imported inputs used by the domestic producers.
