Let the national income model be: Y = C + Io + Go C =x +B(YT) T = y + SY a>0; 00; 0<8 <1 where Y, C, and T are endogenous and I and G are exogenous variables. Solve for ay/aGo, OY/Oy, and Oy/as.

Given that a country will analyze the total benefit of its oil supply-demand in two periods of time by using the following data: Period I Deman curve: P = -0.2 Q₁ + 210 Suply curve: P = 0.04 Q₁ + 30 Interest rate : 10%, Oil reserve : 3.6 billion barrels of oil Units: P in USD, Q in million barrel Period II Deman curve: P = -0.2 Q₂ +210 Suply curve: P = 0.05 Q₂ + 30 Find the efficient allocation! (Q₁, Q₂, P₁, P₁, NB₁, NB₂, TNB), draw a graphical illustration!

How many points (out of the 6 shown) can be explicitly plotted to form the IS curve given the goods market equilibrium?A goods market equilibrium is shown below: A, B, C, D, E, F 32- A goods market equilibrium is shown below: S₁ (Y= 400) 28- Real Interest Rate, r (%) S2(Y=600) S3 (Y = 800) 226 24- A 20- B C 16- 12- E 4- 0- 0 l(r) F 50 100 150 200 250 300 Desired national saving / desired investment We recommend that you drow out the IS curve before answering

Whenever the interest charge for any interest period (a year, for example) is based on the remaining principal amount plus any accumulated interest charges up to the beginning of that period, the interest is said to be: a. effective interest b. compound interest c. simple interest d. nominal interest e. none of the choices
