In the monetarist model, a difference between desired spending and income is caused by either an excess demand for money (MD > MS) or an excess supply of money (MS > MD). An excess demand for money reduces desired spending, and an excess supply increases it. In the Keynesian model, changes in desired spending (particularly in desired investment spending) cause the difference.
New Keynesians account for time in their models
Keynesians say that government should interven in economic activities where as classical say not too
Classical Aggregate Supply function is vertical whereas the Keynesian Aggregate Supply function is positively sloped.
The major difference between the classical model and the Keynesian model is their approach to government intervention in the economy. The classical model believes in a hands-off approach, where the economy will naturally correct itself, while the Keynesian model advocates for government intervention to stimulate economic growth and stabilize fluctuations.
Keynesian model is able to show how leakages and injections can influence the economy. AD-AS model is able to show changes in prices (inflation).
Keynesian economic theory focuses on government intervention to manage economic fluctuations, while classical economic theory emphasizes a hands-off approach with minimal government involvement in the economy.
A
Its a line lol A guideline used in Keynesian economics in conjunction with the consumption line (to derive saving) and the aggregate expenditures line (to identify Keynesian equilibrium). This guideline forms a 45-degree angle with both the horizontal income axis and the vertical consumption expenditure (or aggregate expenditures) axis in the Keynesian graphical analysis.
The difference between consumption and consumption function is that the consumption function is a formula that measures consumer spending.
Income is money coming in, expenditure is money going out (spending).
cheap is when something is not expensive. frugal is to be wise and wary of over spending on something.
Controllable spending is the type of spending that you decide to do. Uncontrollable spending is the type of spending that you have no choice about. Budgets are typically dominated by uncontrollable spending.
