समग्र मांग और उसके घटक
In Class 12 Economics, this topic explains aggregate demand as the total planned expenditure on goods and services in an economy at a given income level. Students study its main components—consumption expenditure, investment, government expenditure and net exports—and understand how they combine as AD = C + I + G + (X − M). The topic connects changes in these components with equilibrium income, output and employment under the chapter Determination of Income and Employment.

Aggregate demand is the total planned expenditure on final goods and services in an economy during a given period. In a simple model it is represented by consumption plus investment, while more complete models may also include government spending and net exports. It is therefore an economy-wide concept, unlike the demand of one person, shop, or product. Option A is correct.
Aggregate consumption is the total spending by households on final goods and services. It is a major component of aggregate demand and usually changes with disposable income, expectations, wealth and other economic factors. Studying it helps economists understand output determination, saving, employment and fluctuations in economic activity. The alternatives either describe an individual preference or make an incorrect statement about the relationship between consumption and income.
Aggregate expenditure represents economy-wide spending on goods and services, while aggregate income arises from producing those goods and services. Their relationship helps explain changes in output, employment and the equilibrium level of national income. If expenditure rises, firms may increase production and employment, subject to available capacity. Thus, option A is correct.
Income determination studies how aggregate demand and aggregate expenditure interact with production to establish the equilibrium level of national income and output. Consumption, saving, investment, government spending and net exports can influence this level. It is therefore a macroeconomic issue involving economy-wide totals, not the preference of one consumer or the design of one product. Option A is correct.
Aggregate demand and aggregate supply determine important economy-wide outcomes. If demand is greater than available supply, prices may rise and firms may expand production in the short run; if demand is insufficient, inventories can accumulate and production and employment may decline. Therefore, their imbalance can affect output, employment and the general price level, making option A correct.
Aggregate demand management uses fiscal, monetary, and related policies to influence total spending in the economy. Its objectives may include reducing recessions and inflation, stabilizing output and income, supporting employment, and maintaining sustainable growth. Policymakers must balance demand support with price and external stability.
Aggregate demand represents total planned spending on an economy’s goods and services. When it falls, firms may face unsold inventories and reduce production. Lower production can reduce the demand for labour, employment, and household income. The final effect depends on prices, expectations, policy responses, and the economy’s capacity.
Aggregate demand is the planned expenditure on an economy's final goods and services. When it falls, inventories may accumulate because firms cannot sell their usual output. Producers may respond by reducing production, working hours, and labour demand. Consequently, employment and income can decline. Therefore, option A describes the demand-output-employment chain.
Fiscal policy consists mainly of government decisions about taxation and public expenditure. Higher government spending can directly increase aggregate demand, while lower taxes can raise disposable income and consumption. Conversely, reduced spending or higher taxes can restrain demand. Through these channels fiscal policy influences output, employment, and price stability. Thus D is correct.
Option C is correct because monetary policy works mainly through the financial system. By changing policy rates, money supply, or credit conditions, the central bank influences borrowing costs and the availability of loans. Lower interest rates may encourage consumption and investment, while higher rates may restrain them; these changes alter aggregate demand and, consequently, output and employment.
Aggregate demand is made up of consumption, investment, government expenditure, and net exports. Studying these components shows which source is driving demand and how fiscal, monetary, trade, or income changes may affect output and employment. It therefore improves macroeconomic diagnosis and policy design.
Aggregate demand management uses fiscal and monetary measures to reduce large fluctuations in economic activity. During weak demand, policy may support output and employment; during excessive demand, it may restrain inflationary pressure. The broad objective is macroeconomic stabilisation of income, output, employment, and prices.
