Consider the market for financial capital and the relationship among saving, investment, and the interest rate. Assume that the economy is in a long-run equilibrium with Y=Y*.

Suppose there is an increase in consumption in this economy. Briefly explain (in 1 sentence without the use a diagram) any shifts in desired investment or national savings and the resulting impact on national savings, investment and the real interest rate.
Suppose the government decides to encourage national saving. Briefly identify (1 sentence) two ways the government could this.
Briefly explain (1-2 sentences) the effects of these actions of government (from part b above) on the economic growth rate.
Briefly explain (1-2 sentences) what the neoclassicals assume about technology in their model of economic growth and what. It meant for economic growth over time.

Expert Solution

a) With increase in consumption , there will be decrease in savings and taking the impact as a whole the national savings rate will decline .

national savings curve will shift leftwards(showing decline) .

Investment will show contraction along the curve (due to decline in savings) .

The real interest rate will rise .

b) The governement can encourage savings by i) Increasing interest rates

ii) Tax breaks on savings.

c) If the interst rates are increased , it will increase the national savings as people will get higher return on savings but it will raise the cost of borrwing , further decreasing the investment. This may have a negative impact on economic growth as investment is necessary to progress economically.

If tax breaks are given on savings , people will save mpore for future and consume less in present . It will increase economic growrth rate in long run but might have negative effect in short run due to decrease in consumption / Aggregate Demand.

d) Neo - classicals assume technology as an exogenous variable in their economic growth theory . The theory states that technology alongwith labour and capital is one of the main drivers of economic growth and must not be ignored. It is necessary to reach a steady state equilibrium.

Assume that the economy of Robsville is currently in long-run equilibrium, with a natural rate of unemployment equal to 6% and an inflation rate of 2%. a) Draw a correctly labeled graph of the short-run Phillips curve, and label the curve as "SRPC". Indicate the point on the SRPC corresponding to the current unemployment and inflation rates labeled as "R". b) On your graph in part (a), draw the long-run Phillips curve, and label it as "LRPC". c) Assume that...

Consider the Canadian economy that is in long run equilibrium with output equal to Y*. Canada and the United States have established a new free trade agreement that results in a significant increase in goods and services imported into the United States from Canada. For the Canadian economy, answer the following questions. use separate diagrams for each question. 1 illustrates the initial equilibrium in a diagram using AD and AS model. explain the diagram 2. what kind of shock occurred...

Consider the AS-AD model where the economy is not in long-run equilibrium, in particular, assume there is a negative output gap (that is, the economy is in a recession). (a) Describe the adjustment under fixed exchange rates if there is no government intervention. (b) Contrast your answer with that under flexible exchange rates

Long-run Macroeconomic Equilibrium and Stock Market Boom Let us assume the economy reaches its long-run macroeconomic equilibrium in 2020. When the economy is in the long run macroeconomic equilibrium, the stock market will also reach its boom. This will in turn lead to increases in stock prices more than expected, and the stock prices will stay high for some period. Answer the following questions based on the scenarios of long macroeconomic equilibrium and consequent stock market boom. Which curve will...

Assume that the economy is at a long-run equilibrium, with unemployment at 5%, and inflation at 2% pa. Suppose a shock causes a very large increase in the cost of crude oil and gas. Assume that Ireland does not produce any oil or gas, and imports large amounts of oil and gas. The shock causes unemployment to rise to 9%, and inflation to rise to 4% pa. Using the data, write out the equation of the Phillips curve before, during,...

7. Short-run supply and long-run equilibrium Consider the competitive market for copper. Assume that, regardless of how many firms are in the industry, every firm in the industry is identical and faces the marginal cost (MC), average total cost (ATC), and average variable cost (AVC) curves shown on the following graph. The following diagram shows the market demand for copper. Use the orange points (square symbol) to plot the initial short-run industry supply curve when there are 10 firms in...

Suppose the economy is in long-run equilibrium.

Scenario 1 - Pessimism Suppose the economy is in long-run equilibrium. Then because of corporate scandal, international tensions, and loss of confidence in policymakers, people become pessimistic regarding the future and retain that level of pessimism for some time. Scenario 1 - Pessimism. Which curve shifts and in which direction? aggregate demand shifts right aggregate demand shifts left aggregate supply shifts right. aggregate supply shifts left.

Consider an economy that begins in long-run equilibrium. Suppose that there is a wave of pessimism that reduces investment demand at any given real interest rate. That is, suppose that the investment demand curve shifts down and to the left. Use the IS-LM diagram and the aggregate supply - aggregate demand diagram to show how this shift down of the investment demand curve affects the interest rate, income, investment, the price level, consumption, and the supply of real money balances...
