Answer: 110%
Step-by-step explanation:
The effective rate of protection is used in measuring the final tariff in a particular sector and it's expressed as:
g = (t -ai,ti) / (1 - ai)
where,
g = effective protection rate
ai = nominal tariff rate = 0.6
t = cost of intermediate input = 0.5
ti = nominal tariff on intermediate input = 0.1
The computer price here is $800 while the input price is 60% of $800 which will be:
= 60% × $800 = $480
nominal tariff rate = 480/800 = 0.6
Nominal tariff on final goods, t = 50% = 0.5
Tariff on imported input, ti = 10% = 0.1
Using the formula:
g = (t -ai,ti) / (1 - ai)
g = [0.5 - (0.6×0.1)] / (1 - 0.6)
g = (0.5 - 0.06) / 0.4
g = 0.44/.0.4
g = 1.10
g = 110%
The effective rate of protection is 110%
