Chapter 10 Flashcards
4 Classical position beliefs
- Say’s law holds, so that insufficient demand in the economy is unlikely
- Wages, prices and interest rates are flexible
- The economy is self-regulating
- Laissez-faire is the right and sensible economic policy
Efficiency Wage Models
Models holding that it is sometimes in the best interest of business firms to pay their employees higher-than-equilibrium-wage rates.
Assumptions for the simple Keynesian model
- The price level is assumed to be constant until the economy reaches its full employment or Natural Real GDP level
- No foreign sector. Model = closed economy.
- The monetary side of the economy is excluded.
Keynes’ 3 basic points on consumption
- Consumption depends on disposable income (income minus taxes)
- Consumption and disposable income move in the same direction
- When disposable income changes, consumption changes by less
Consumption Function
Relationship between consumption & disposable income.
Consumption is directly related to disposable income and is positive even at zero disposable income.
C = Co + (MPC)(Yd)
Autonomous consumption (Co)
The part of consumption that is independent of disposable income.
Marginal Propensity to Consume (MPC)
Ratio of the change in consumption to the change in disposable income: MPC = ∆C / ∆Yd
3 Ways to increase C
- Raise autonomous consumption
- Raise disposable income
- Raise the MPC
Saving
Difference between disposable income and consumption:
Saving = Disposable income - Consumption
S = Yd - [Co - (MPC)(Yd)]
Marginal propensity to save
Ratio of the change in saving to the change in disposable income:
MPS = ∆S/∆Yd
The MPC/MPS equality
MPC + MPS = 1
Multiplier process
An initial rise in autonomous consumption leads to a rise in consumption for one person generating additional income for another person and leading to additional consumption spending by that person and so on….
Multiplier
The number that is multiplied by the change in autonomous spending to obtain the overall change in total spending.
= 1/(1 - MPC)
If the economy operates below Natural Real GDP, then the multiplier is the number that is multiplied by the change in autonomous spending to obtain the change in Real GDP.
5 Statements on the AD/AS and the Simple Keynesian Model
- Price level is constant until Natural Real GDP is reached
- AD curve shifts if there are changes in C, I or G
- The economy could be in equilibrium and in a recessionary gap too
- Private sector may not be able to get the economy out of a recessionary gap.
- Government may have a management role in the economy. (May have to raise aggregate demand)
Progressive Income Tax
An income tax system in which one’s tax rate rises as taxable income rises
Proportional Income tax
An income tax system in which a person’s tax rate is the same regardless of taxable income.
Regressive Income Tax
An income tax system in which a person’s tax rate declines as his or her taxable income rises.
Budget Deficit
Government expenditures greater than tax revenues
