Duesenberry has made two observations regarding the factors affecting consumption.
a) The consumption expenditure depends not only on his current income but also past income and standard of living. As the individuals are accustomed to a particular standard of living, they continue to spend the same amount on consumption even though the current income is reduced.
b) Consumption is influenced by demonstration effect. The consumption standards of low income groups are influenced by the consumption standards of high income groups. In other words, the poor people want to imitate the consumption pattern of rich. This results in spending beyond their income level.

2	i.e. Movement of goods or visible trade	Trade in both visible and non visible items.

(i) In the Keynesian model, output is determined mainly by aggregate demand.
(ii) The aggregate demand is the amount of money which entrepreneurs expect to get by selling the output produced by the labourers employed.
(iii) Aggregate demand (spending) is the amount that households, firms, the governments and the foreign purchasers would like to spend on domestic output
Aggregate demand has four components:
1. Consumption demand (C)
2. Investment demand (I)

Net Export ( export - import) (X - M)
AD = C + I + G + (X - M)

(ii) Public welfare is the main motive.
(iii) There is equality in the distribution of income and wealth. E.g. China
Mixedism:

(i) Currency Inflation:
The excess supply of money in circulation causes rise in price level.
(ii) Credit Inflation
When banks are liberal in lending credit, the money supply increases and thereby rising prices.
(iii) Deficit Induced Inflation:
The deficit budget is generally financed through printing of currency by the Central Bank. As a result, prices rise.
(iv) Profit Induced Inflation:
When the firms aim at higher profit, they fix the price with higher margin. So, prices go up.
(v) Scarcity Induced Inflation:
Scarcity of goods happens either due to fall in production (e.g. farm goods) or due to hoarding and black marketing.
(vi) TaxInducedInflation:
(1) Increase in indirect taxes like excise duty, custom duty and sales tax may lead to rise in price.
(2) This is also called taxflation.

5. FDI is also influenced by the income generated from the trade and regional integration schemes.
6. FDI accelerates the economic growth by facilitating essential imports needed for development programs like capital goods, technical know-how, raw materials, other inputs and even scarce consumer goods.

Law
According to Keynes, "men are disposed as a rule and on the average to increase their consumption as their income increases but not by as much as the increáse in their income".
Propositions
1. When income increases, consumption expenditure also increases, but by a smaller amount
(a) When income increases from 120 to 180; consumption also increases from 120 to 170 but the increase in consumption is less than the increase in income, 10 is saved.
2. The increased income will be divided in some proportion between consumption expenditure and saving
(a) When income increases to 180 and 240, it is divided between consumption (170 and 220) and saving (10 and 20)
3. Incrcascs in income always lead to in incrcase in both consumption and saving
(a) Increases in income to 180) and 240; lead to increased consumption 170 and 220; increased saving 10 and 20.
(b) It is clear from the widening area below the C curve and the saving gap between 45^o line and C curve.

Introduction
According to J. B. Say "Supply creates its own demand"
Explanation
A person receives his income from production which is spent on the purchase of goods and services produced by others. For the economy as a whole, therefore, total production equals total income.
Criticisms
(i) According to Keynes, supply does not. create its demand. It is not applicable where demand does not increase as much as production increases.
(ii) Automatic adjustment process will not remove unemployment. Unemployment can be removed by increase in the rate of investment.
(iii) Money is not neutral. Individuals hold money for unforeseen contingencies, businessmen keep cash reserve for future activities.
(iv) Say's law is supply creates its own demand and there is no over production. Keynes said that over production is possible
(v) Keynes regards full employment as a special case because there is underemployment in capitalist economies.
(vi) State intervention is needed when there is over production and mass unemployment.

(i) National income is of great importance for the economy of a country.
(ii) National income helps us to know the relative importance and contribution of each sector. We could find how income is produced, how it is distributed, how much is spent, saved or taxed.
(iii) National income data is used to formulate monetary policy, fiscal policy and other policies.
(iv) Data regarding gross income, output, saving and consumption is uscd in economic planning.
(v) National income data is used to build economic models in short run and long run.
(vi) It is used to make international comparison, inter regional comparison and inter temporal comparison of growth of the economy during different periods.
(vii) If income is equally distributed, the per capita income will reflect the economic welfare of the country.

(i) A financial intermediary is a bank or other institution that serves as a link between lenders and borrowers.
(ii) They typically accept savings deposits from consumers and then lend money to consumers and businesses to finance purchases of goods and services or for investment purposes.

(i) On the supply side, the low level of real income means low savings.
(ii) The low level of saving leads to low investment and to deficiency of capital.
(iii) The deficiency of capital, in turn, leads to low levels of productivity and back to low income.
(iv) Low Income ⟶ Low Saving ⟶ Low Investment ⟶ Low Production ⟶  Low Income

The value of total output of goods and services produced in an economy in a year

1. Multiplier highlights the importance of investment in income and employment theory.

3. Hence, Keynes is regarded as the ‘Father of Modern Macro Economics’.
