a) “According to the long-run classical model, there will be a decrease in the world interest rate and the world level of investment when the aging populations of industrial countries start running down their savings and, at the same time, the investment appetite of emerging economies begins to slow down.” True/False, explain with the aid of one diagram for the world market for loanable funds. (10 points) Note: The world as a whole is a closed economy.

b) A new study shows that the level of total factor productivity increases and, at the same time, the labour force participation rate falls. According to the long run classical model, what happens to the equilibrium levels of the real interest rate, the real rental price of capital, and the real wage? Explain in words and support your answer by using ONE loanable funds market diagram, ONE labour market diagram, and ONE rental market for capital diagram. (15 points)

11. 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 saving, Public saving, and National saving; ii. the amount of net...
