example, a railway line connecting a backward region, an irrigation work to prevent
famine conditions in an area and so on. In this sense, most public debt is productive.
But public debt may be contracted to finance a war. Such debt is unproductive because
it does not create an asset, it is a dead weight debt or a useless burden on the community
iii). Redeemable and Irredeemable Debt. The redeemable debts are those which the
government promises to pay off in future at a specified date: they are terminable loans.
Irredeemable debt refers to a debt which may not be redeemed at all but on which the
government promises to pay the interest regularly. These loans may be known as
perpetual debt. The redeemable loans may be further classified into short period and
long period loans depending upon the period of redemption.
iv). Funded and Unfunded Debt. Public debt is also classified into funded and unfunded or
floating debt. Broadly speaking, funded debt is a long-term debt, undertaken for
creating a permanent asset and the government normally makes arrangements about the
mode and time of repayment. Unfunded or floating debt is a relatively short period debt,
meant to meet current need. The government undertakes to pay off the unfunded debt in
a very short period, say within six months.
v). Compulsory and Voluntary Debt. Generally, government debt is of a voluntary type,
that is individuals and institutions are invited to take up government bonds freely. On
the other hand, a compulsory loan implying force is not common in modern times.
However, pressure may be applied by the government at certain times in selling its
bonds.
vi). Marketed and non marketed debt. A marketed debt is one in which the debt
instruments are negotiable. That is it can be freely bought and sold in the market. Non-
marketable debts are those debts such as savings bonds which cannot be bought and
sold in stock-exchange markets.
vii). Callable and non callable. Callable debts are those debts which the government can
repay even before the period of maturity, whenever it is found convenient for the
government to do so. The government can pay back these types of debts, whenever it
enjoys surplus funds, or when the prevailing interest rates are low. Non- callable debts
cannot be repaid in this manner. It can be repaid only at the time of maturity.
viii). Short term, medium term and long term debt. Short term debts are those debts which
mature within a period of three to six months. These loans are drawn from the central
bank by using the credit instrument of treasury bills. Medium term loans are those loans
which mature within a period of one to ten years. Long-term loans mature for over ten
