Public expenditure refers to the spending by the government to provide public goods and services, which includes social goods like education, healthcare, and infrastructure.

Aggregate demand represents the total demand for finished goods and services in an economy, which effectively dictates the total planned expenditure by households, firms, and the government.

According to the consumption function, as income rises, saving typically increases because the marginal propensity to save is positive. Households save a portion of additional income. While the relationship may not be strictly linear at very high income levels (the savings rate can plateau), the general principle that higher income leads to higher savings is well-established in economics.

In Keynesian theory, aggregate demand is the primary driver of output and employment in the short run. Changes in aggregate demand lead to changes in the equilibrium level of income and employment.

In short-run macroeconomic models, factors of production such as land, capital stock, and the level of technology are held constant to isolate the effects of changes in labor and aggregate demand.

Inventory investment refers to the change in the stock of unsold goods, raw materials, and work-in-progress held by firms, whereas fixed capital investment refers to assets like machinery and buildings.

Autonomous consumption represents the level of consumption that occurs even when income is zero, as individuals must consume to survive. Therefore, it is generally positive, not zero.

Autonomous consumption is the minimum level of consumption required for survival, which exists regardless of income level. Thus, it cannot be zero.

An open economy is an economy in which there are economic activities between the domestic country with the other countries.

Hence, for an open economy, aggregate demand is equal to Consumption + Investment + Government expenditure + (X-M) where X is the income from Exports and M is the expenditure on imports

AD = C + I + G + (X-M)

In a competitive market, the equilibrium price and quantity are established where the quantity demanded by consumers equals the quantity supplied by producers, which is the intersection point of the demand and supply curves.
