I need good explanation. Don't copy from chegg

C = 50 + 0.9 · (Y – T) I = 50 – 1000 -r where Y is real output and r is the real interest rate. Government purchases and taxes are G = 500, T = 500. The money market equilibrium curve-or LM curve-is M Y P 5i where P is the price level and i is the nominal interest rate. The Central Bank (CB) is initially supplying M = 10000 units of money, and expected inflation is aº = 0.05. The long-run aggregate supply (LRAS) is Y, = 1000. Suddenly, there is a climate shock that changes the marginal propensity to consume (MPC), and the consumption function changes to C' = 50 + 0.8 - (Y – T). 1. Explain how the long-run values of (r, i) are determined before the climate shock. 2. Which, if any, of the graphs from Appendix A best depicts the long-run change in the interest rate(s) due to the climate shock? Explain. 3. Explain how the long-run values of (Y, P) are determined before the climate shock.

When deciding how much of your income to save for retirement, should you consider the real or the nominal interest rate that your savings will earn?  Explain, applying what you know about the difference between real and nominal from our application of GDP.

Explain how a drop in GDP can influence the level of the interest rate (in 7 lines maximum). A captioned graphic illustration is required

Economics An analyst needs to adjust the nominal GDP for the years 2000 and 2010 into real terms to conclude his comparison analysis. The nominal GDP in 2000 was $672 billion and $1,690 billion in 2010; the real interest rate was 6.79% in 2000 and 3.71% in 2010; the 2000 deflator was 24 and 51 in 2010. What is the real gain?

Michael works in communications. On December 31, 2017, he bought an existing business with servers and a building worth $300,000. During 2018, he bought new servers for $500,000. The market value of his older servers fell by $200,000. What was Michael's gross investment during 2018?

Suppose the nominal rate of interest on a savings account is 15%, the real rate of interest is 3%, and the tax rate on nominal interest is 20%. Which of the following is true? A saver would lose 9% real interest. A saver would neither gain nor lose real interest. A saver would earn 12% real interest. A saver would earn 2.4% real interest.
