Chapter 19, Problem 1DQ
To determine
Macroeconomic instability.
Expert Solution & Answer
Explanation of Solution
In economics, the mainstream of macroeconomic instability is Keynesian-based and it focuses on aggregate spending and its components. Changes in investment spending are significant and lead to changes in the
Investment spending refers to wide variation and a ‘multiplier effect’ that expands these changes into greater amount in aggregate demand; these can cause demand pull inflation in the forward direction or a recession. A mainstream view of instability could arise on the supply side; it leads to decreases in a nation’s aggregate supply which may threaten the economy by simultaneous causing cost push inflation or recession.
Economics Concept Introduction
Concept introduction:
Demand pull inflation: Demand pull inflation refers to increasing price due to increasing the aggregate demand.
Cost push inflation: Cost push inflation refers to increasing price due to increasing the cost of production.

- For the linear IS-LM model, the goods market and the money market are in equilibrium when. Suppose that the economy is characterized by the following equations: (Y;r) = ( 1200 ; 6), Y-C-IG=0, C-Co-c(Y-T)=0,I-Io+hr=0, and kY-ur-M^s=0, which are satisfied for Co=60, lo=150, G=250, T=200, M^s=60, with the parameters c=0.8, k=0.1, h=10, and u=10. How are the equilibrium and affected, a) if "h" (the sensivity of the demand for investment to the interest rate) decreases to 5? b) if "u" (the sensitivity of the demand for real money balances to the interest rate) decreases to 5?arrow_forward13. Assuming that an economy’s aggregate demand is given by its domestic consumption C and investment I, AD = C + I = c0 + c1Y + I. In the economy’s goods market equilibrium, this equals its output: AD = Y. Solving for Y this yields: Y = [1/(1 -c1 )] (c0+ I) Given this equation, which of the following statements is correct? 1. The multiplier is given by 1 – c1. 2. The boost in the economy’s output is the same, regardless of whether the aggregate demand shock comes from an increase in investment I or in autonomous consumption c0. 3. The larger the marginal propensity to consume (c1), the smaller the multiplier. 4. If c1 = 1/3, then a £1 million increase in investment would result in a £2 million increase in output. 14.

- 81.Assume that in a certain economy the LM curve is given by Y = 2,000r – 2,000 + 2(M/P), and the IS curve is given by Y = 8,000 – 2,000r + u, where u is a shock that is equal to +200 half the time and –200 half the time. The price level (P) is fixed at 1.0. The natural rate of output is 4,000. The government wants to keep output as close as possible to 4,000 and does not care about anything else. Consider the following two policy rules: i. Set the money supply M equal to 1,000 and keep it there. ii. Manipulate M from day to day to keep the interest rate constant at 2 percent. a.Under rule i, what will Y be when u = +200? What will Y be under rule i when u = –200? b.Under rule ii, what will Y be when u = +200?
