- The following equations relate to a certain economy, peruse them and answer thefollowing questions.T = 0.75Y (tax rate)L= Y - 100r (Real money demand)M = 300 (Read money supply)C = 200 + 0.25Y d (Consumption function)I = 20 - 10r (Investment function)G = 30 (government purchases) i) Derive equations fro IS and LM curvesii) Determine the rand y pair at which the two markets are clearing iii) Compute the values of C, I and L.1. According to the Bureau of Economic Analysis, during therecession of 2007–2009, household saving as a fraction of dis-posable personal income increased from a low of just over1 percent in the first quarter of 2008 to 5 percent in the secondquarter of 2009. All else equal, what impact would this changein saving have on the MPC, MPS, and multiplier? How wouldthis change affect equilibrium output when planned invest-ment changes? 2. Assume in a simple economy that the level of saving is –500 whenaggregate output equals zero and that the marginal propensity tosave is 0.2. Derive the saving function and the consumption func-tion, and draw a graph showing these functions. At what level ofaggregate output does the consumption curve cross the 45° line?Explain your answer and show this on the graph.1. Let's use the Euler equation two ways. First, to find out the optimal consump- tion path, taking the interest rate as given (Chapter 9 of GLS) and then to find out the equilibrium interest rate that wil Choose sidebar display for saving and investment, taking the consumption path as given (Chapter 11 of GLS). Both times, the utility function will be the same: Uln(c)+0.9ln(+1) So the future counts 90% as much as the present. In Part 1, income each period is 100, and the interest rate is 20%. In Part 2, consumption in each period is 100-in other words, income each period is 100, but income isn't storable (it's "manna"), so you have to consume it or lose it. Answer the following questions. Part 1: What is optimal consumption each period? In period t of this two- period world, will this person be borrowing or saving or neither? ⚫ Part 2: What is the equilibrium interest rate between these two periods? If the equilbrium interest rate were lower than that level, would that create a…
