A. Classical/General Equilibrium Model: Assume that GDP (Y) is 8,500B. Consumption (C) is given by the equation C = 210B + 0.9(Y – T). Investment (I) is given by the equation I = 1,200B – 100B(r), where r is the real rate of interest. Taxes (T) are 400B and government spending (G) is 500B. Show/type your work/calculations!

Assume that the world works according to the Classical model. In a small open economy, output is produced according to a Cobb-Douglas production function, consumption is equal to C=40+0.6(Y-T) and the investment function is I=280-10r. You know that the output produced is Y=900, government spending is G=150, taxes are T=90 and that the world real interest rate is 4% (r*=4). In all the questions below, make sure to explain your answers and show all your work. a. Compute: i. Private...

Economists in Fundlandia, a closed economy, have collected the following information about GDP and public savings in their country: Y = 1000 G = 100 T = 100 They further estimate that national savings and investment are governed by the following expressions: S = 150 + 50*r I = 600 - 100*r Where r is the country's real interest rate in % terms (thus if you find r = 5, then r is 5%).
