Consider two countries, A and B, whose respective industries produce goods A and B. Total world output of the good is given by Q

castortr0y [4]

Answer: hello your question is poorly written attached below is the complete question

answer :

a) 31.5

b) 24.5

Step-by-step explanation:

Total world output of good given ( Q ) = qA + qB

world demand ( P ) = 100 - Q

cost function for country A = cA (qA) = 8qA

cost function of country B = cB(qB) = 3qB

total world emission = 0.5Q

emission per unit good = 0.5

<u>a) Determine total world emissions when both countries compete in a Cournot fashion</u>

Q = 63

therefore Total world emission = 0.5 ( Q )

= 0.5 ( 63 ) = 31.5

attached below is the detailed solution

<u>b) Determine the total world emissions after Country A enacts a carbon tax</u>

Q = 49

Therefore Total world emission after tax = 0.5 ( Q )

= 0.5 ( 49 ) = 24.5

attached below is the detailed solution

Mr. Larson is debating between investing $10,000 into an account that pays 4% interest compounded daily or 4.9% compounded weekl

AVprozaik [17]

Answer:

4.9% weekly

Step-by-step explanation:

The compound interest formula is ...

A = P(1 +r/n)^(nt)

where A is the account balance that results from investing P at rate r compounded n times per year for t years.

Filling in the values for the two scenarios, we find ...

A = 10,000(1 +0.04/365)^(365·3) ≈ 11,274.89

A = 10,000(1 +0.049/52)^(52·3) = 11,582.74

The higher interest rate will earn Mr. Larson the most money in three years. (4.9% weekly)
