Why would Mexico’s government create barriers to international trade?

Explanation:

Normally the two main reasons for an international trade barrier to be implemented is so that a precious good/resource is maintained and protected within the borders or in order to retaliate against a trade partner for something. Therefore Mexico most likely would implement a trade barrier for one of these two reasons. Most likely another trade partner has increased the Mexican import fees for one of their products, and as retaliation, Mexico would place a trade barrier on one of the goods that "that" specific country requires.

Calculation for what will the portfolio's new beta be

First step is to Calculate the weight of each investment

Stock E$ 50,000/$ 2,00,000

Stock E=0.25

Stock B$ 50,000/$ 2,00,000

Stock B=0.25

Stock C$ 50,000/$ 2,00,000

Stock C=0.25

Stock D$ 50,000/$ 2,00,000

Stock D=0.25

Now let calculate the portfolio new beta

WeightBeta

Stock E0.25* 1.45 = 0.36

Stock B 0.25* 0.80 = 0.20

Stock C 0.25* 1.00= 0.25

Stock D 0.25* 1.20 = 0.30

Total 1.11

(0.36+0.20+0.25+0.30)

Therefore portfolio's new beta will be 1.11
