Answer: b. The instrument is correlated with x1.
d. The instrument does not directly influence y, except through x1.
Explanation:
Based on the information given in the question, the necessary characteristics of a suitable instrument include:
• The instrument is correlated with x1.
• The instrument does not directly influence y, except through x1.
Some of the criteria for an instrument variable are the fact that it should have a causal effect on independent variable and also the dependent variable isn't directly affected except through the independent variable which is x1 in this scenario.
Therefore, the correct option are B and D.
Answer:
The beta of stock T is 1.82
Explanation:
The portfolio beta is made up of the weighted average of the individual stock betas in the portfolio.
The formula for portfolio beta is,
Portfolio beta = wA * beta of A + wB * beta of B + ... + wX * beta of X
The weight of stock T in the portfolio is = 1 - (0.11 + 0.56) = 0.33 or 33%
Let beta of Stock T be x. The beta of Stock T is:
1.47 = 0.11 * 0.84 + 0.56 * 1.39 + 0.33 * x
1.47 = 0.0924 + 0.7784 + 0.33x
1.47 - 0.0924 - 0.7784 = 0.33x
0.5992 / 0.33 = x
x = 1.815 rounded off to 1.82
