Question 41 (a).
Briefly explain the objective factors of consumption functions.
Objective Factors:
(i) Income Distribution:
If there is large disparity between rich and poor, the consumption is low because the rich people have low propensity to consume and high propensity to save.

(ii) Price level:

  • Price level plays an important role in determining the consumption function.
  • When the price falls, real income goes up; people will consume more and propensity to save of the society increases.

(iii) Wage level:

  • Wage level plays an important role in determining the consumption function and there is positive relationship between wage and consumption.
  • Consumption expenditure increases with the rise in wages.
  • Similar is the effect with regard to windfall gains.

(iv) Interest rate:

  • Rate of interest plays an important role in determining the consumption function.
  • Higher rate of interest will encourage people to save more money and reduces consumption.

(v) Fiscal Policy:
When government reduces the tax the disposable income rises and the propensity to consume of community increases.

(vi) Consumer credit:

  • The availability of consumer credit at easy installments will encourage households to buy consumer durables like automobiles, fridge, computer.
  • This pushes up consumption.

(vii) Demographic factors:

  • Ceteris paribus, the larger the size of the family, the grater is the consumption.
  • Besides size of family, stage in family life cycle, place of residence and occupation affect the consumption function.

(viii) Duesenberry hypothesis:
Duesenberry has made two observations regarding the factors affecting consumption.

  • The consumption expenditure depends not only on his current income but also past income and standard of living.

(ix) Windfall Gains or losses:
Unexpected changes in the stock market leading to gains or losses tend to shift the consumption function upward or downward.

(b) Explain the keynes psycological law of consumption asumptions.
Keynes’s Law is based on the following assumptions:

The other variables such as income distribution, tastes, habits, social customs, price movements, population growth, etc. do not change and consumption depends on income alone.

(ii) Existence of Normal Conditions:

  • The law holds good under normal conditions.
  • If, however, the economy is faced with abnormal and extraordinary circumstances like war, revolution or hyperinflation, the law will not operate.
  • People may spend the whole of increased income on consumption.

(iii) Existence of a Laissez-faire Capitalist Economy:

  • The law operates in a rich capitalist economy where there is no government intervention.
  • People should be free to spend increased income.
  • In the case of regulation of private enterprise and consumption expenditures by the State, the law breaks down.

Question 42 (a).
What are the effects of Inflation on the Economy?
The effects of inflation can be classified into two heads:

  1. Effects on Production and
  2. Effects on Distribution.

1. Effects on Production:
When the inflation is veiy moderate, it acts as an incentive to traders and producers. This is particularly prior to full employment when resources are not fully utilized. The profit due to rising prices encourages and induces business class to increase their investments in production, leading to generation of employment and income.

  • However, hyper-inflation results in a serious depreciation of the value of money.
  • When the value of money undergoes considerable depreciation, this may even drain out the foreign capital already invested in the country.
  • With reduced capital accumulation, the investment will suffer a serious set-back which may have an adverse effect on the volume of production in the country.
  • Inflation also leads to hoarding of essential goods both by the traders as well as the consumers and thus leading to still higher inflation rate.
  • Inflation encourages investment in speculative activities rather than productive purposes.

2. Effects on Distribution:

  • Debtors and Creditors: During inflation, debtors are the gainers while the creditors are losers.
  • Fixed-income Groups: The fixed income groups are the worst hit during inflation because their incomes being fixed do not bear any relationship with the rising cost of living.
  • Entrepreneurs: Inflation is the boon to the entrepreneurs whether they are manufacturers, traders, merchants or businessmen, because it serves as a tonic for business enterprise.
  • Investors: The investors, who generally invest in fixed interest yielding bonds and securities have much to lose during inflation.

Question 45 (a).
Explain the methods of debt redemption.
The process of repaying a public debt is called redemption. The Government sells securities to the public and at the time of maturity, the person who holds the security surrenders it to the Government. The following methods are adopted for debt redemption.
(i) Sinking Fund:

  • Under this method, the Government establishes a separate fund known as “Sinking Fund”.
  • The Government credits every year a fixed amount of money to this fund.
  • By the time the debt matures, the fund accumulates enough amount to pay off the principal along with interest.
  • This method was first introduced in England by Walpol.

(ii) Conversion:

  • Conversion of loans is another method of redemption of public debt.
  • It means that an old loan is converted into a new loan.
  • Under this system a high interest public debt is converted into a low interest public debt.
  • Dalton felt that debt conversion actually relaxes the debt burden.

(iii) Budgetary Surplus:

  • When the Government presents surplus budget, it can be utilised for repaying the debt.
  • Surplus occurs when public revenue exceeds the public expenditure.
  • However, this method is rarely possible.

(iv) Terminal Annuity:

  • In this method, Government pays off the public debt on the basis of terminal annuity in
    equal annual installments. .
  • This is the easiest way of paying off the public debt.

(v) Repudiation:

  • It is the easiest way for the Government to get rid of the burden of payment of a loan.
  • In such cases, the Government does not recognise its obligation to repay the loan.
  • It is certainly not paying off a loan but destroying it.
  • However, in normal case the Government does not do so; if done it will lose its credibility.

(vi) Reduction in Rate of Interest:
Another method of debt redemption is the compulsory reduction in the rate of interest, during the time of financial crisis.

(vi) Capital Levy:

  1. When the Government imposes levy on the capital assets owned by an individual or any institution, it is called capital levy.
  2. This levy is imposed on capital assets above a minimum limit on a progressive scale.
  3. The fund so collected can be used by the Government for paying off war time debt obligations.
  4. This is the most controversial method of debt repayment.

(b) Describe the various types of deficit in budget.
The Indian Government budget, budget deficit is of four major types.

1. Revenue Deficit:
It refers to the excess of the government revenue expenditure over revenue receipts. It does not consider capital receipts and capital expenditure. Revenue deficit implies that the government is living beyond its means to conduct day-to-day operations.
Revenue Deficit (RD) = Total Revenue Expenditure (RE) – Total Revenue Receipts (RR) When RE – RR > 0

2. Budget Deficit:
Budget deficit is the difference between total receipts and total expenditure (both revenue and capital)
Budget Deficit = Total Expenditure – Total Revenue

3. Fiscal Deficit:
Fiscal deficit (FD) = Budget deficit + Government’s market borrowings and liabilities

4. Primary Deficit:
Primary deficit is equal to fiscal deficit minus interest payments. It shows the real burden of the government and it does not include the interest burden on loans taken in the past. Thus, primary deficit reflects borrowing requirement of the government exclusive of interest payments.
Primary Deficit (PD) = Fiscal deficit (PD) – Interest Payment (IP)

Question 46 (a).
Briefly explain classification of Public expenditure.

(i) Classification on the Basis of Benefit:

  • Public expenditure directly benefiting particular group of persons and indirectly the entire society, e.g., social security, public welfare, pension, unemployment relief etc.
  • Public expenditure conferring a special benefit on some individuals, e.g., subsidy granted to a particular industry.
