(b) Describe the types of exchange rates.
Exchange rates are also in the form of (a) Nominal exchange rate (b) Real exchange rate (c) Nominal Effective Exchange Rate (NEER) and (d) Real Effective Exchange Rate (REER).
If 1 US Dollar = Rs 75
Nominal exchange rate = 75/1 = 75.
This is the bilateral nominal exchange rate.
Real Exchange Rate = \(\frac{ep_f}{p}\)
P = Price levels in India
P = Price levels in India
e = nominal exchange rate
If a pen costs Rs 50 in India and it costs 5 USD in the US,
Real Exchange Rate = = \(\frac{75×5}{5}\) = 7.5
If real exchange rate is equal to 1, the currencies are at purchasing power parity.
If the price of the pen in US = 0.66 USD, then,
the real exchange rate = = \(\frac{0.66×75}{50}\)
then it could be said that the USD and Indian Rupee are at purchasing power parity.

Question 46 (a).
Explain the Cambridge approach.
Cash Balance approach of Marshall equation.
Marshall’s Equation
The Marshall equation is expressed as:
M is the quantity of money
Y is the aggregate real income of the community
P is Purchasing Power of money
K represents the fraction of the real income which the public desires to hold in the form of money
Thus, the price level P = M/KY or the value of money in terms of this equation can be found out by dividing the total quantity of goods which the public desires to holdout of the total income by the total supply of money.
According to Marshall’s equation the value of money is influenced not only by change in M, but also by changes in K.

Explain the methods of debt redemption.
Methods of Redemption of Public Debt:
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:

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

(ii) Sinking Fund:
Conversion of loans is another method of redemption of public debt.

  1. It means that an old loan is converted into a new loan.
  2. Under this system a high interest public debt is converted into a low interest public debt.
  3. Dalton felt that debt conversion actually relaxes the debt burden.

(iii) Budgetary Surplus:

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

(iv) Terminal Annuity:

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

(v) Repudiation:

  1. It is the easiest way for the Government to get rid of the burden of payment of a loan.
  2. In such cases, the Government does not recognise its obligation to repay the loan.
  3. It is certainly not paying off a loan but destroying it.
  4. 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.

(vii) 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

2 Economic model is based on mathematical modeling. Econometric model is based on statistical modeling.
3 Economic model is focused on establishing the logical relationships between the variables in the model. Econometric model is focused on estimating the magnitude and direction of relationship between the variables.
4 Economic model is applied in stating the theoretical relationship into mathematical equations. Econometric model is applied in stating the empirical extent of the economic model.
5 Economic model believes that outcome is certain and exact. So disturbance term is not required. Econometric modeL Hjelieveg that outcome is certain but not exact. So disturbance term plays the vital role.
6 Economic model is deterministic in nature. Econometric model is stochastic in nature.
