Assume that Vietnam has a demand for laptops of Q=20.000.000 - 5000 P,

We have firm A, B and J.

Suppose that the marginal costs are the only costs of production and that there are no transport costs MCA=MCB=2500, MCJ=1900

Vietnamese customs applies a 15.8% add valorem tariff on the sales price of laptops sold by company J in Vietnam,
