You obtain the following estimates for an AR(2) model of some returns data

Business
1 answer:
Sergio039 [100]3 years ago
4 0

Answer:

AR(2) model is not stationary

Explanation:

Given model  :  Yt = 0.803yt-1   +  0.682yt-2 +  ut  ---- ( 1 )

ut = noise error process

Aim : Check estimated model for stationarity

<em>step 1 : </em>represent the estimated polynomial of the model ( where: ut ∪ N(o,б^2 ) rewrite equation 1

Yt - 0.803yt-1  - 0.682yt-2  = ut  ------- ( 2 )

hence the polynomial can be represented as :

( 1 - 0.803B - 0.682B^2 )Yt = ut

Characteristic of the obtained polynomial can be represented as ;

1 - 0.803λ - 0.682λ^2 - 1 = 0

attached below is the remaining part of the solution

Olivia likes to eat both apples and bananas. At the grocery store, each apple costs $0.20 and each banana cost $0.25. Olivia’s u
icang [17]

Answer:

Therefore, Olivia should buy 10 apples and 8 bananas to maximize her utility.

Explanation:

Let A represent the number of apples bought and B represent the number of bananas bought. Therefore since Olivia has $4 to spend:

0.2A + 0.25B = 4       (1)

Also, the tangency condition can be used to find the optimal amount of A to relative to B. It is give as:

MU_A/P_A=MU_B/P_B\\\\\frac{3\sqrt{\frac{B}{A} } }{0.2}= \frac{3\sqrt{\frac{A}{B} } }{0.25}\\\\15\sqrt{\frac{B}{A} }=12\sqrt{\frac{A}{B} }\\\\squaring\ both\ sides:\\\\\frac{225B}{A} =\frac{144A}{B}\\\\225B^2=144A^2\\\\B^2=0.64A^2\\\\Taking\ square\ root:\\\\B=0.8A

Put B = 0.8A in equation 1:

0.2A + 0.25(0.8A) = 4

0.2A + 0.2A = 4

0.4A = 4

A = 10

B = 0.8(A) = 0.8(10) = 8

Therefore, Olivia should buy 10 apples and 8 bananas to maximize her utility.
