Adam Smith argued that all nations can be benefitted when there is free trade and specialisation in terms of their absolute cost advantage
The Theory
(i) According to Adam Smith, the basis of international trade was absolute cost advantage.
(ii) Trade between two countries would be mutually beneficial when one country produces a commodity at an absolute cost advantage over the other country which in turn produces another commodity at an absolute cost advantage over the first country.
Assumptions
1. There are two countries and two commodities (2 x 2 model).
2. Labour is the only factor of production
3. Labour units are homogeneous
4. The cost or price of a commodity is measured by the amount of labour required to produce it.
5. There is no transport cost.
Illustration
Absolute cost advantage theory can be illustrated with the help of the following example.

(iii) From the illustration, it is clear that India has an absolute advantage in the production of wheat over China and China has an absolute advantage in the production of cloth over India
(iv) Therefore, India should specialize in the production of wheat and import cloth from China. China should specialize in the production of cloth and import wheat from India
(v) This kind of trade would be mutually beneficial to both India and China.

(i) The equilibrium rate of exchange is determined in the foreign exchange market according to the general theory of value, by the interaction of demand and supply,
(ii) Y axis represents exchange rate, be cos value of rupee in terms of dollars
(iii) X axis represents demand and supply of forex.
(iv) E is the equilibrium point where DD intersects SS. The exchange rate is P₂.

Introduction
(i) Monetary Policy is the macroeconomic policy laid down by the Central Bank towards the management of money, supply and interest rate. It is associated with Milton Friedman
1) Neutrality of Money
(i) Wicksteed, Hayek and Robertson are the chief exponents of neutral money.
(ii) They say that the monetary authority should aim at neutrality of money in the economy.
(iii) Monetary changes cause distortion and disturbances in the proper functioning of the economic system of the leading to all economic fluctuations.
2) Exchange Rate Stability
(i) It is a traditional objective from the Gold Standard period
(ii) When there was disequilibrium in the balance of payment, it was automatically corrected by movements.
(iii) It was popularly known as "Expand Currency and Credit when gold is coming in; Contract currency and credit when gold is going out."
(iv) If there is instability in the exchange rates, it would result in outflow or inflow of gold resulting in unfavorable balance of payments.
3) Price Stability
(i) Crustave Cassel and Keynes suggested price stabilization as a main objective of monetary policy.
(ii) Stable Price creates public confidence, promotes business activity and ensures equitable distribution of income and wealth leading to prosperity and welfare
(iii) Price stability does not mean price rigidity or price stagnation.

(iv) Flexible monetary policy is the best solution.
6) Equilibrium in the Balance of Payments (BoP)
(i) World trade was faster than world liquidity.
(ii) Increasing deficit in BoP reduces the ability of an economy to achieve other objectives.
(iii) Many less developed countries reduce their imports which adversely affects development activities, so monetary authority should make efforts to bring equilibrium in the BoP.

Causes:
Increase in Money Supply:
1. Increase in money supply leads to increase in aggregate demand.
2. The higher the growth rate of nominal money supply, the higher is the rate of inflation.
Increase in Disposable Income:
1. When disposable income increases, it raises their demand for goods and services.
2. Disposable income may increase with the rise in national income or reduction in taxes or saving of the people.
Increase in Public Expenditure:
1. Government activities have been expanding due to developmental activities and social welfare programmes.
2. This is also a cause for price rise.
Increase in Consumer Spending:
1. The demand for goods and services increases when they are given credit to buy goods on hire-purchase and instalment basis.
Cheap Monetary Policy:
1. Cheap monetary policy leads to increase in the money supply which raises demand for goods and services.
Deficit Financing:
1. To meet the expenses, government resorts to deficit financing by borrowing from the public and even by printing more notes.
2. This raises aggregate demand leading to inflation.
Black Assets, Activities and Money:
1. It leads to corruption, tax evasion.
2. People spend black money lavishly.
3. Black marketing and hoarding reduces the supply of goods and increases.
Repayment of Public Debt:
1. Whenever government repays its past internal debt to the public, money supply increases.
Increase in Exports:
1. When exports are encouraged, domestic supply of goods decline, prices rise.
Effects:
On Production:
1. When inflation is very moderate it is an incentive to traders and producers.
2. When profit increases the business men increase their investments in production leading to more employment and income.
3. Hyper inflation leads to depreciation of the value of money and discourages savings.
4. It may even drain out the foreign capital already invested in the country.
5. The reduced capital accumulation, discourage entrepreneurs and business men from taking business risk.
6. Inflation also leads to hoarding of essential goods by traders and consumers leading to still higher inflation rate.
7. Encourages investment in speculative activities rather than productive purposes.
On Distribution:
Debtors and Creditors:
1. During inflation debtors are the gainers.
2. Debtors had borrowed when the purchasing power of money was high and now repay the loans when the purchasing power of money is low due to rising prices.
Fixed-income Groups:
1. They are worst hit because their incomes being fixed has no relationship with the rising cost of living.
Entrepreneurs:
1. Inflation is a boon to manufacturers, traders, merchants, businessmen, because it serves as a tonic for business enterprise.
2. They get windfall gains as the prices of their stocks suddenly go up.
Investors:
1. Those who invest in fixed interest yielding bonds and securities lose during inflation.
2. Those who invest in shares stand to gain by rich dividends and appreciation in value of shares.

Introduction
The concept of multiplier Was first developed by R.F. Khan in terms of employment. J.M Keynes redefined it as investment multiplier.
Definition
Multiplier is defined as the ratio of the change in national income to change in investment.
\(K=\Delta Y / \Delta I\)
The value of multiplier depends on MPC.
\(\mathrm{K}=\frac{1}{1-\mathrm{MPC}} \text { since } \mathrm{MPC}+\mathrm{MPS}=1\)
\(k=\frac{1}{N 118}\)
Multiplier is inversely related to MPS and directly with MPC.
If MPC is, 0.75, MPS is 0.25 then K=4.00
\(\frac{1}{1-0.75} \text { or } \frac{1}{0.25}=4\)

MPC	MPS	k
0.00	1.00	1
0.10	0.90	1.11
0.50	0.50	2.00
0.75	0.25	4.00

Working
(i) Suppose government undertakes investment expenditure equal to र100 cr on public works.
(ii) Income of labourers and suppliers of materials increases by र100 cr
(iii) If MPC is 0.8 that is 80 %. र80 cr is spent on consumption र20 cr salved
(iv) Suppliers of goods get an income of र80 cr. They spend र64 cr (ie 80% of र80 cr).
(v) In this manner consumption expenditure and increase in income act in a chain like manner.

Cyclical unemployment:
(i) During the downturn phase (recession and depression) of trade cycle, income and output fall leading to cyclical unemployment.
(ii) It is caused by deficiency of effective demand
Structural unemployment:
(i) Unemployment due to massive and deep rooted changes in economic structure leads to structural unemployment.
(ii) Lack of demand for the product or shift in demand to other products cause this type of unemployment.
(iii) (e.g.) rise in demand for mobile phones has adversely affected the demand for cameras, tape recorders
Disguised unemployment:
(i) It occurs in agriculture when more people are there than required. Even if some workers are withdrawn, production does not suffer.
Actual marginal productivity is zero, less or negative.
(i) Seasonal unemployment
1. In agriculture and agro based industries like sugar, production activities are carried out only in some seasons.
2. These industries offer employment only during that season in a year.
3. People remain unemployed during the off season.
4. Seasonal unemployment takes place from demand side also (eg) ice cream industry, holiday resorts
(ii) Frictional unemployment (Temporary unemployment)
1. It arises due to imbalance between supply of labour and demand for labour.
2. It is because of immobility of labour, lack of necessary skills, break down of machinery, shortage of raw materials.
3. The persons who lose jobs and in search of jobs also come under frictional unemployment
(iii) Educated unemployment
1. Educated people are underemployed or unemployed when qualification does not match the job.
2. Faulty education system, lack of employable skills, mass student turnout and preference for white collar jobs are highly responsible for educated unemployment.

Introduction:
National income can be measured by the social accounting method. Under this method, the transactions among various sectors such as firms, households, government are recorded and their interrelationships traced.
Firms:
undertake productive activities. They employ factors of production to produce goods and services.
Households:
Households are consuming entities. They represent the factors of production, who receive payment for services rendered by them to firms. (i) Households consume the goods produced by the firms. There is a circular flow of money between these two groups.
Government:
The Government sector refers to the economic transactions of public bodies at all levels-centre, state and local. Their purchases may be financed through taxation, public borrowings. The government provides public health, education. They satisfy the collective wants of society. But Post Offices and railways are separated from the Government sector and included as "Firms".
Rest of the world:
It relates to international economic transactions - income, export, import external loan transaction, and allied overseas investment income and payments.
Capital sector:
(i) Capital sector refers to saving and investment activities. It includes the transactions of banks, insurance corporations, financial houses. These are not included under "Firms".
(ii) The economy is also divided into primary, secondary tertiary and quaternary sectors.
Conclusion:
The social accounting framework is useful for economists as well as policy makers, because it represents the major economic flows and statistical relationships among various sectors of the economic system. It is possible to forecast the trends of economy more accurately.

Net Barter Terms of Trade
1. This was developed by Taussig in 1927.
2. The ratio between the prices of exports and of imports is called net barter terms of trade.
3. Viner calls it commodity terms of trade.
4. \(\mathrm{T}_{\mathrm{n}}=\left(\mathrm{P}_{\mathrm{x}} / \mathrm{P}_{\mathrm{m}}\right) \times 100\)
5. Tn is Net Barter Terms of Trade
6. Px is Index number of export prices
7. Pm is Index number of import prices
8. This measures the gain from International Trade.
9. If T_n is greater than 100, it is terms of trade which means that for a rupee of export, more of imports can be received by a country.
Gross Barter Terms of Trade
1. Developed by Taussig in 1927 as an improvement over the net terms of trade.
2. It is an index of relationship between total physical quantity of imports and the total physical quantity of exports.
\(\mathrm{Tg}=\left(\mathrm{Q}_{\mathrm{m}} / \mathrm{Q}_{\mathrm{x}}\right) \times 100\)
3. Q_m is Index of import quantities
4. Q_x is Index of export quantities
5. If for a given quantity of export, more quantity of import can be consumed by a country, the terms of trade are favourable.

(v) classical unemployment of Q₁-Q₂ can be solved by a wage cut.
(vi) If wages are allowed to fall to the market clearing level, unemployment is solved

(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 build economic models in short run and long run.
(iv) Data regarding gross income, output, saving & consumption is used in economic planning.
(v) National income data is used to build economic models in short run and long run.
