Question 1 There are three policy variables that the government and the Bank of Zambia control that have a major influence on the economy. Draw small sketch graphs and quick indications of the effects on Y and i of each variable moving both up and down while holding the other policy variables constant (i.e. there are six situations to consider). The first one is done for you as an indication of how to do the others: 1. Increase in G IS-LM Model IS Y increases LM, i increases IS; IS, Y

Please no written by hand solution Consider a scenario of a closed economy in the short run where price level is fixed. Assume that bothtaxes and money supply increase in a way that keep output constant in equilibrium (suppose that themarginal propensity to consume is less than one). Which of the following may result from the policychange?a) It will lead to an increase in investment but a decrease in consumption.b) It will result in an increase in investment but a decrease in government spending.c) It will lead to an increase in investment and private saving.d) It will decrease investment but increase in public saving.
1. Using the AS-AD model, graph and explain the effects of Covid-19 on the U.S. macroeconomy by comparing 2019 vs. 2020. Label the years on all curves, the axis, and the equilibrium. Ignore macroeconomic policy responses, such as the CARES act. Which curves shifted which direction, and why? 2. Now introduce any macroeconomic policy response. What curves shift which direction, and why? 3. What were the equilibrium quantities for both axis?

Calculate an expression for the IS, MP and AD curves ( r= ?, IS Y= ?, AD Y=?)B. Let AS curve be given by the relation: π = 6 + 1.5 (Y - 25.5) (i.e. the price shock is zero). What are the equilibrium values of inflation, output and the real interest rate(π, Y, r)?C. Suppose government purchases are raised from $3.0 trillion to $3.5 trillion. What are new short-run equilibrium inflation values, output and the real interest rate (π, Y, r}?D. Suppose a financial crisis begins, and ƒ increases ƒ = 3. (Assume government purchases are again as in part (a). What are the new short-run equilibrium values of inflation, output, and the interest rate (π, Y, r}?(Please solve all the parts with numerical steps so it could be practiced easily)

The imaginary country of Harris Island has theaggregate supply and aggregate demand curves as Table24.3 shows. a. Plot the AD/AS diagram. Identify theequilibrium.b. Would you expect unemployment in thiseconomy to be relatively high or low?c. Would you expect concern about inflation in thiseconomy to be relatively high or low?d. Imagine that consumers begin to lose confidenceabout the state of the economy, and so ADbecomes lower by 275 at every price level.Identify the new aggregate equilibrium.e. How will the shift in AD affect the originaloutput, price level, and employment?
Use the extended IS-LM model graph to show where the US economy is functioning now given that the current u is 7.9% and the full-employment (FE) u (aka un) is 4%. [Hint: if u > u FE then Y< Y FE.] Indicate the gap and provide its name. Let’s assume that a “second covid-19 wave” in December 2020 leads to more lockdowns, so that many more businesses struggle to survive and face an increase in their probability of bankruptcy. What is this “shock” and what would it do, cet. par., to your graph of part a.? Explain any shift(s). Let’s assume the Federal Reserve fixes the gap in your graph of part b. Provide appropriate name(s) and policy tools and show what will happen in your graph of part b. What role, if any, does the “zero lower bound” play?
6.1.What is an AD-AS model and what does such a model as per the givendiagram essentially focus on?6.2.Discuss the diagram in detail by first explaining what leads to step Step 1(representing a shift in curves on the diagram) and indicating what occursto cause shifts in some of the curves. Then discuss Step 2 (whichrepresents other macroeconomic changes) and indicate what happens toother variables when there are shifts in some of the curves as per Step 1. 6.3.What, in general, do the points of intersection between the AS and AS2curves and the AD curve show?6.4.When the LAS curve moves to the right to LRAS2, what exactly do thepoints of intersection between the AS and AS curves and the AD1 curve,indicated as point 1 and point 2, reflect on the diagram?
Congratulationst You have been appointed an economic policy adviser to the United States, You are told that the economy is significantly abowe futtemplyoment GDP. Based on this inlormation, how can the economy would adjust to reach LR.SR Equilbrium (Classical View)? The economy wilt experience low unemployment rate, pushing wages up, and increasing the pelces of a key input (labor). shatting the sAS to the left (up). The economy will experience high unemployment rate, pushing wages down, and reducing the prices of a key input (labor). shiting the SAS to the right (down). The econoriny wil experience low unemployment rate, decreasing inceme, which will eventually shift the AD to the left. The eooncmy will experience low unemployment rate, pushing wages up, and increasing the prices of a key input (labor), shiting the sAs to the night (down).
Suppose in the real business cycle model that there is a simultaneous temporary increase inboth current government spending and in the current money supply. Draw diagrams for thelabour, goods and money market, and the production function. Determine the equilibriumeffects of these two shocks occurring simultaneously on employment, output, consumption,investment, money, real wages, the real interest rate, and the price level. Provide a detailedeconomic analysis explaining your results with the aid of the diagrams.
Course: Macroeconomic - IS-LM Model Prove mathematically the following: Given an increase in the proportional tax on income(t), what happens to the level of output and to the tax?" . Hint: for demostration, use the IS general function for a closed economy Y = C + I + G, where C = a + c*YD and YD = Y + TR - Y*t (where t = proportional income tax) and realize changes i.e., from "t1" to "t2"
Suppose that in Macroland the consumption and the investment have a negative relationship withthe real interest rate and positive relationship with Y. The Central Bank of the country targets acertain nominal interest rate and lets the money supply adjust in order to reach that interest rate.a. Draw a graph of the IS-LM model in this situation.b. Suppose that the Central Bank announces an increase of the interest rate in the future.Represent graphically the initial position of IS-LM curves. Then, show the IS-LM curves of thefuture, after the announced increase in the interest rate is implemented. (Assume that the ISis constant.).c. Suppose that agents today take into consideration the resulting income of the future whendeciding the amount of consumption and investment. Show what happens to the IS-LMcurves today after the announcement of the CB (tip: the CB is NOT increasing the nominalinterest rate today).d. The government decides to step in and avoid any deviation of Y from the initial…
i neeed it in word form.. not handwrittten Explain, with the aid of three separate IS-LM-FE diagrams, how a decrease in government purchases will affect real output, real interest rate and the general price level in three steps:(i) before the general price level adjusts;(ii) when the general price level is adjusting;(iii) after the price adjustment process is completed.Is the general price level increasing or decreasing during the price adjustment process? Explain the intuition of your answer with reference to the AD-AS framework.
