The main focus of the Interest Theory is on the charged amount paid against borrowed money. Though money is the most familiar form of asset at the time of lending, yet during arrangements of fiscal lease, Interest Theory considers other asset forms like consumer goods through hire purchase, shares, factories, aircrafts and other primary assets as well. In each of these cases, the rate of interest is charged on the total asset values, just like it is calculated on money.
According to the Loanable Funds Theory of Interest, the rate of interest is calculated on the basis of demand and supply of loanable funds present in the capital market. The concept formulated by Knut Wicksell, the well-known Swedish economist, is among the most important economic theories.
The concept of Monopoly deals with a steady market condition where only one good or service provider exists, to rule the industrial sector single-handedly, without undergoing any sectoral competition. The characteristic features of the Theory of Monopoly are:
Absence of feasible products acting as replacements or substitutesLack of competition on the economic levels, with respect to the availability of goods or servicesMonopolists are basically price-makers of their own products

Oligopoly is a form of market where there is domination of a limited number of suppliers and sellers called Oligopolists. In reality, it is the Oligopoly market which exists, having a high degree of market concentration.

These firms require strategic planning to consider the reactions of other participants existing in the market. This is precisely why an oligopolistic market is subject to greater risk of connivances.

The standard definition of efficiency in economics believes that the Theory of Prefect Competition will end in a totally efficient result.
The concept of Perfect Competition is based on certain hypotheses as mentioned and described below:
