A market analysis using the aggregate supply and aggregate demand model of j m keynes

By Mary Hall Updated February 9, — 9: Aggregate demand is a macro-economic concept representing the total demand for goods and services in an economy. This value is often used as a measure of economic well-being or growth. Fiscal policy affects aggregate demand through changes in government spending and taxation.

Monetary Policy

The curve is upward sloping in the short run and vertical, or close to vertical, in the long run. Net investment, technology changes that yield productivity improvements, and positive institutional changes can increase both short-run and long-run aggregate supply.

Institutional changes, such as the provision of public goods at low cost, increase economic efficiency and cause aggregate supply curves to shift to the right. Supply Shocks - Supply shocks are sudden surprise events that increase or decrease output on a temporary basis.

Examples include unusually bad or good weather or the impact from surprise military actions. Unless the price changes reflect differences in long-term supply, the LAS is not affected.

Changes in Expectations for Inflation - If suppliers expect goods to sell at much higher prices in the future, their willingness to sell in the current time period will be reduced and the SAS will shift to the left.

The Aggregate Demand Curve The aggregate demand curve shows, at various price levels, the quantity of goods and services produced domestically that consumers, businesses, governments and foreigners net exports are willing to purchase during the period of concern.

The curve slopes downward to the right, indicating that as price levels decrease increasemore less goods and services are demanded. Factors that can shift an aggregate demand curve include: Real Interest Rate Changes - Such changes will impact capital goods decisions made by individual consumers and by businesses.

Lower real interest rates will lower the costs of major products such as cars, large appliances and houses; they will increase business capital project spending because long-term costs of investment projects are reduced.

The aggregate demand curve will shift down and to the right.

Higher real interest rates will make capital goods relatively more expensive and cause the aggregate demand curve to shift up and to the left.

Changes in Expectations - If businesses and households are more optimistic about the future of the economy, they are more likely to buy large items and make new investments; this will increase aggregate demand.


The Wealth Effect - If real household wealth increases decreasesthen aggregate demand will increase decrease Changes in Income of Foreigners - If the income of foreigners increases decreasesthen aggregate demand for domestically-produced goods and services should increase decrease.

The net result will be an increase decrease in aggregate demand. Inflation Expectation Changes - If consumers expect inflation to go up in the future, they will tend to buy now causing aggregate demand to increase.The IS-LM model describes the aggregate demand of the economy using the relationship between output and interest rates.

In a closed economy, in the goods market, a rise in interest rate reduces aggregate demand, usually investment demand and/or demand for consumer durables.

Keynes on the other hand argued that due to rigidities in the market (sticky prices, labor unions, menu costs, etc.) the price adjustment would not be instantaneous and hence the additional demand, in the short run will have to be created by the govt.

by spending more. In contrast a recession in a major export market will lead to a fall in exports and an inward shift of aggregate demand. Changes in household wealth Changing share and property prices affect the level of wealth. Identify the combined shifts in long-run aggregate supply and aggregate demand that could unambiguously explain the simultaneous occurrences of an increase in equilibrium real GDP and increase in equilibrium price level.

I describe a multi-good model in which I interpret the definitions of aggregate demand and supply found in the General Theory through the lens of a search theory of the labor market. I argue that Keynes'.
