In the short run, there is typically a lot of movement in goods prices but little movement in quantities.

The consumption function used in the model shows that consumption decreases as disposable income increases.

In the model, if aggregate demand is less than output, the economy is in equilibrium.

The "Paradox of Thrift" suggests that if everyone tries to save more, it will always lead to higher total savings and a stronger economy.

The equation Y = Z is a behavioral function that describes how firms always set output.

A recession is defined as a period of declining aggregate output.

The multiplier is calculated as 1 / (1 - C₁).

For the first part of the course, the economy is modeled as a closed economy, meaning exports and imports are assumed to be positive.

An increase in autonomous consumption (C₀) will shift the aggregate demand (ZZ) curve downwards.

The slope of the aggregate demand (ZZ) line in the Keynesian Cross diagram is equal to the marginal propensity to consume (C₁).

The 45-degree line on the Keynesian Cross diagram represents the equilibrium condition where output equals aggregate demand.

A larger marginal propensity to consume (C₁) leads to a smaller multiplier.

If the government wants to cool down an overheated economy, it could use a contractionary fiscal policy, which would shift the ZZ curve down.

In the model, investment (I) and government spending (G) are initially treated as constants determined outside the model.

In the full definition of aggregate demand (Z), imports are subtracted because they represent demand for foreign, not domestic, production.

A government transfer payment, like a stimulus check, is counted as government expenditure (G) in the model.

The marginal propensity to consume (C₁) is a number between zero and one.

In the short run, the primary driver of equilibrium output is the economy's productive capacity (e.g., capital and labor).

A contractionary fiscal policy could involve the government increasing taxes (T).

If the marginal propensity to consume is 0.8, the value of the multiplier is 5.

According to the lecture, consumer sentiment is a key factor in the short run because it directly influences the marginal propensity to consume (C₁).

The IS curve is introduced as an alternative way to find equilibrium, where the condition is Investment = Saving.

The determination of output in the long run is the primary focus of business cycle analysis.
