Aggregate demand and aggregate supply, based on a problem from “Principles of Economics” by N. Gregory Mankiw
a) List the components of country’s GDP in an open economy. For each component, provide an example of an event that would cause a shift of the aggregate demand curve to the right.b) What will be the effect of such events on the level of prices and the real outcome in the short run? Provide a graph.c) What will be the effect of such events on the level of prices and the real outcome in the longrun? Update your graph
Suppose that firms become very pessimistic about future business conditions and cut heavily on investment in capital equipment.
Show the long-run equilibrium of the economy. Explain what happens to Price level and Quantity of Output in the long run equilibrium. Explain in words why the aggregate quantity of output demanded changes between the short run and the long run. [No policy involvement]
Suppose the government provides incentives (e.g. lower company tax) to firms that engage in high levels of research and development.How would this affect firms’ allocation between different types of investment? Explain.
How would this affect the interest rate? Explain. What happens to the quantity of investment overall? Explain.What happens to the short-run aggregate supply curve? Explain. What happens to the long-run aggregate supply curve? Explain. What happens to the value of the dollar? Explain.g What happens to the quantity of net exports demanded? Explain.h What happens to aggregate demand? Explain.
