Question 31 5 points Save Answ In year 2018, the government of Qatar spent is 143 billion Qatari Riyal (the national currency of Qatar). The GDP of Qatar in the same year is 1,121 billion Qatari Riyal. Qatar's desired consumption and desired investment during the year can be summarized by the following equations: cd = 1,000 – 5,000r, || /d = 800 – 3000r, %3D cd is the desired consumption in billions of Qatari Riyal, 7º if the desired investment in billions of Qatari Riyal, and r is the real interest rate in decimal form. where What is the equilibrium real interest rate, r*, in %?

On the following graph, show the impact of the increase in government purchases on the interest rate by shifting one or both of the curves. Supply X Demand 2 10 20 30 40 50 QUANTITY OF LOANABLE FUNDS (Billions of dollars) 12 IN TEREST RATE 10 0 0 60 ģ Demand Supply ? Suppose that for each one-percentage-point increase in the interest rate, the level of investment spending declines by $1.25 billion. by According to the change you made to the loanable funds market in the previous scenario, the increase in government purchases causes the interest rate in the money market to from 6% to %. The change in the interest rate causes the level of investment spending to $ billion. by After the multiplier effect is accounted for, the change in investment spending will cause the quantity of output demanded to $ billion at each price level.
