5. Suppose an economy is hit by a flood and its natural resources decreases. a) Show graphically using AD-AS model how the price level and output are affected in the short-run. b) Can the government use monetary policy to offset the effects on price level and output, explain?
2. Suppose country A has a central bank with full credibility, and country B has a central bank with no credibility. Assume that in 2020, both countries are hit with the same COVID-19 shock.If the both central banks announce an autonomous easing policy to reduce the unemployment rate, a) How does the credibility of each country’s central bank affect the speed of adjustment of the aggregate supply curve to policy announcements? b) How does this result affect output stability? (Use aggregate supply and demand diagrams to demonstrate)
11. Applying the AD-AS model Aa Aa Financial crises, such as the one that impacted many developed countries starting in 2007, decrease banks' ability and willingness to make loans. Decreased availability of credit decreases businesses' ability to make investment purchases and consumers' ability to buy goods and services. As a result, a financial crisis is a negative shock for an economy. The following graph shows an economy's aggregate demand curve and its short-run and long-run aggregate supply curves after a financial crisis has pushed it into recession. Suppose that the government decides not to use stabilization policy and allows the economy to adjust on its own. Determine which curve, the aggregate demand curve or the short-run aggregate supply curve, shifts when the economy adjusts in the long run. Use either the purple line (triangle symbols) to plot a new aggregate demand curve or the tan line (dash symbols) to plot a new short-run aggregate supply curve, to show the economy in…
An economy has: R = 10 +.ly, C= 14 + 9YD, G= 25, I = 75 -r, NX = 30 -.06y - .5p, MD = 25y-r, MS = 15 and ASo = 2p. A negative AS shock occurs: AS, = 2p – 60. a. Provide a diagram showing AS/AD to illustrate how real GDP and the price level are affected by this AS shock. A government can offset this AS shock by increasing the money supply OR increasing government spending. They won't do both. Calculate level of money supply MS= b. and the level of government spending G = that would be necessary to offset this AS shock.
If the economy begins at an equilibrium at potential output, a negative aggregate demand shock has which of the following effects in the short-ru? a. output and prices increase and unemployment falls below the natural rate b. output and prices increase and unemployment rises above the natural rate c. output and prices decrease and unemployment rises above the natural rate d. output and prices decrease and unemployment falls below the natural rate
4. Using the aggregate demand and supply model, demonstrate the effect of a $100 billion dollar open market sale. (Use a diagram and explain carefully).
9. Money Supply Suppose an economy is in long-run equilibrium. The central bank raises the money supply by 5 percent. Use your diagram to show what happens to output and the price level as the economy moves from the initial to the new short-run equilibrium. RANDO LHAS Aggregale Supply * A Demand Quantity of Oulpul Now adjust the graph to show the new long-run equilibrium. Aggregate and - Aggregate Supply What causes the economy to move from its short-run equilibrium to its long-run equilibrium? The government increases taxes to curb aggregate demand. The government increases spending to increase aggregate demand. O Nominal wages, prices, and perceptions adjust downward to this new price level. O Nominal wages, prices, and perceptions adjust upward to this new price level. Which of the following is true according to the sticky-wage theory of aggregate supply as a result of the increase in the money supply? Check all that apply. Nominal wages at the initial equilibrium are equal to…
ון רבSuip Reset the graph and click on the blue square to apply a negative supply shock the the economy. Then adjust the movable point to view the effects of potential policy responses to the negative supply shock. Use what you observe to answer the questions that follow. a. In response to the effects of a negative supply shock, policymakers decide to decrease aggregate demand. What are the effects of this choice? O an increase in aggregate output, and an increase in the aggregate price level an decrease in aggregate output, and an decrease in the aggregate price level an increase in aggregate output, and an decrease in the aggregate price level an decrease in aggregate output, and an increase in the aggregate price level b. What are the overall tradeoffs with regard to this choice? Policymakers have chosen to fight inflation by increasing AD, but this further reduces aggregate output and makes the recession worse. Policymakers have chosen to fight inflation by decreasing AD, but this…
5. Consider the following changes in the sticky-wage model. a. Suppose labor contracts are fully indexed for inflation so that as inflation changes. That is, the nominal wage is to be adjusted to fully compensate for changes in the consumer price index. How does full indexation alter the AS curve in this model? b. Suppose that now indexation is only partial. That is, for every increase in the CPI, the nominal wage rises, but by a smaller percentage. How does partial indexation alter the AS curve in this model?
