Having more relevant instruments... a. is a problem because instead of being just identified, the regression now becomes overidentified. b. will typically result in a more efficient TSLS estimator c. will typically result in larger standard errors for the TSLS estimator. d. May result in the TSLS being inconsistent in large samples

d. May result in the TSLS being inconsistent in large samples

Step-by-step explanation:

Two-stage least squares (TSLS), regression analysis is a statistical technique that is used for two distinct stages of variables regression, so, when there are more relevant instruments than required, is like having a larger sample size in that the more information is available for use in the Instrumental Variables regression (IV).

i can't see the picture : /

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
