1. Productivity Theory:

According to productivity theory, interest can be defined as a reward for availing the services of capital for the production purpose.

Labor that is having good amount of capital produces more as compared to the labor who is not assisted by good amount of capital.

For example, farmer having tractor to plough the field produces more as compared to the farmer who does not have it. Thus, interest is the payment for the productivity of capital.

However, the productivity theory is criticized on the following grounds:

1. Focuses only on the causes for what the interest is paid, not on the determination of interest rates.
2. Assumes that interest is paid due to the productivity of capital. In such a case, pure interest should vary as per the productivity of the capital. However, pure interest is the same in money market during the same period of time.
3. Lays emphasis on the demand of interest, but ignores the supply side of capital.
4. Fails to explain how the interest is paid for the loan borrowed for consumption purposes.

2. Abstinence or Waiting Theory:

The abstinence theory was propounded by Senior. According to him, interest is a reward for abstinence. When an individual saves money out of his/her income and lends it to other individual, he/she makes sacrifice. The term sacrifice implies that the individual refrains from consuming his/her whole income that he/she could spent easily. Senior advocated that abstaining from consumption is unpleasant. Therefore, the lender must be rewarded for this. Thus, as per Senior, interest can be regarded as the reward for refraining from the use of capital.

Abstinence theory was also criticized by a number of economists. According to the theory, an individual feels unpleasant when they save as it reduces his/her consumption. However, rich people do not feel unpleasant while saving because they are able to meet their requirements.

Therefore, Marshall has replaced the term abstinence with waiting and described saving in terms of waiting. He states that saving is done by transferring the present requirement to the future and the person needs to wait for meeting those requirements. However, people do not want to wait rather they are motivated to save money by providing a certain amount of interest.

3. Austrian or Agio Theory:

Austrian theory is also termed as psychological theory of interest. This theory was advocated by John Rae and Bohm Bawerk in an Austrian school. According to Austrian theory, interest came into existence because present goods are preferred over future goods. Therefore, the present goods have premium with them in the form of interest. In other words, present satisfaction is of greater concern as compared to future satisfaction.

Therefore, future satisfaction has certain type of discount if compared with present satisfaction. The interest is the discounted amount that is required to be paid for motivating people to invest or transfer their present requirements to future. For example, an individual has to make a choice between two options.

He/she can either have Rs. 500 now or the same amount after a year. In such a case, he/she would prefer to have Rs. 500 in present. However, in case, the individual has a choice of getting Rs. 500 in present and Rs. 600 after one year.

In such a case, he/she would be more inclined toward getting Rs. 600 after a year. Thus, the extra payment of Rs. 100 would compensate the sacrifice involved in delaying his/her present satisfaction. The extra payment of Rs. 100 in the given case is considered as interest.

Agio theory’ has been criticized by various economists on the following grounds:

1. Lays too much emphasis on the supply aspect and ignores the demand aspect
2. Does not focus on the determination of rate of interest

4. Classical or Real Theory:

Classical theory helps in the determination of rate of interest with the help of demand and supply forces. Demand refers to the demand of investment and supply refers to the supply of savings. According to this theory, rate of interest refers to the amount paid for saving.

Therefore, the rate of interest can be determined with the help of demand for saving money to be invested in the capital goods and the supply of savings. Let us understand the concept of demand of investment. Capital goods are used for the production of consumer goods and provide returns continuously for many years.

However, a certain degree of uncertainty is associated with capital goods due to their future use. In addition, operation and maintenance costs are involved in using capital goods. This makes organizations to calculate the net expected return on the marginal cost that is represented as the percentage of cost of capital good.

In case, an organization has similar type of capital goods, then the increase in one more capital good would not yield them high revenue. The increase in the rate of interest would result in the fall of demand of capital goods.

Figure-18 shows the demand for capital investment:

In Figure-18, MRP represents the marginal revenue productivity curve. When the demand of capital is OM, then the rate of interest is Or. The net rate of return becomes equal to the current rate of interest (Or) at the OM demand of capital.

In case, the rate of interest decreases to Or’, then the demand of capital increases to OM’. The net rate of return is equal to Or’ when the amount of capital demanded is OM’. The demand for capital goods increases with a decrease in the rate of interest.

On the other hand, the supply of capital increases by the amount saved by an individual and the saving is done by transferring the present requirement to the future requirement. The rate of interest would increase with the increase in the amount of saving by an individual.

The rate of interest can be determined with the help of demand of investment and supply of savings. It would be the point of equilibrium where demand and supply intersects each other or get equal.

Figure-19 shows the determination of rate of interest with the help of demand and supply curves:

In Figure-19, SS is the supply curve of saving and II is the demand curve of investment that intersect each other at Or rate of interest with quantity of saving and investment is OM. OM represents the amount that is lent, borrowed and used for investment. The rate of interest can be changed by changing the demand and supply of savings and investment.

The classical theory is criticized by Keynes due to various reasons, which are as follows:

1. Assumes the full employment of resources, which is not true in reality. This is because if one resource is reduced from one production process, then it would be utilized for other production process. On the contrary, if resources are available in abundant, then there is no need to save them.
2. Assumes that investment can be increased only when individuals reduce their consumption. This is because if the consumption is less, then the saving would increase, which would lead to the increase in investment. However, if the demand of capital goods decreases, then the incentive to produce capital goods would also decrease. This would result in the decrease of investment.
3. Assumes that there is no change in the income level of an individual. Thus, according to classical theory, saving and investment become equal due to change in rate of interest. However, according to Keynes theory, savings and investment become equal because of changes occur in the income level of an individual.

5. Loanable Fund Theory:

Loanable fund theory agrees with the view that time preference plays an important role in determining the occurrence of interest. This theory is also termed as neo-classical theory of interest. According to neo-classical economists, interest is the amount paid for loanable funds. It focuses on the determination of rate of interest with the help of demand and supply of loanable funds in the credit market. Let us understand the concept of supply of loanable funds.

The supply of loanable funds depends on the following factors:

1. Savings:

Act as one of the sources of loanable funds. The loanable funds in the form of saving are classified as ex-ante saving and Robertsonian sense. Ex-ante saving refers to the saving that an individual plans according to his/her expected income and expenditure in the starting of a year or financial year or for a month.

On the other hand, Robertsonian sense refers to the saving that is produced by taking the difference of previous period income and present period consumption. In both the types of savings, the savings are different at different rate of interest. Savings are dependent on the income level that vanes with the rate of interest. The increase in the rate of interest would result in the increase of the level of saving and vice versa.

In the context of organizations, the amount left after distributing the profit in the form of dividends is termed as the saving of an organization. The savings of an organization depends on the rate of interest prevailing in the market. Increased rate of interest would encourage organizations to increase savings instead of borrowing money from loan market.

2. Dishoarding:

Involves reduction in the money stock of an organization. Therefore, in the previous money stock, the liquidity of money is high that can be utilized in the present time as loanable funds. The higher the rate of interest, the more would be the money dishoarded and vice versa.

3. Credit by bank:

Refers to the loan provided by bank to the organizations. Banks can increase or decrease the money lend to an organization on the basis of certain criteria. The supply of loanable funds increases with the increase in the money created by banks. The supply curve is interest elastic for loanable funds. The higher the rate of interest, the more the bank would lend money and vice versa.

4. Disinvestment:

Refers to the situation when the existing capital goods of an organization are reduced or the stock of the organization is less than the previous stock. In such a condition, the fund that is used for the replacement purposes are used as loanable funds.

According to Bober, ”Disinvestment is encouraged by the somewhat by a high rate of interest on loanable funds. When the rate is high, some of the current capital may not produce a marginal revenue product to match this rate of interest. The firm may decide to let this capital run down and to put the depreciation finds in the ban market”

After determining the factors that influence the supply of loanable funds, let us study the demand for loanable funds. The demand for loanable funds depends on investment, consumption, and hoarding of income. Organizations require loanable funds to a greater extent for expanding the stock of capital goods, such as machines and buildings.

The demand for loanable funds depends on the extent to which organizations require loanable funds. Interest is the price at which the loanable funds can be bought. Organizations require loanable funds at which the net rate of return on capital goods is equal to the rate of interest.

The higher rate of interest demotivates organizations to buy capital goods or expand their stock of capital goods. Therefore, the demand of loanable funds is interest elastic for organizations; therefore, the demand curve would slope downwards.

Another major constituent of demand for loanable funds is the requirement of funds b) individuals for consumption. Generally, individuals require loanable fund when they desire to purchase something out of their budget or the consumer goods that they cannot afford from their present income. The lower the rate of interest, the higher would be the demand for loanable goods. Therefore, the demand for loanable funds is interest elastic for individuals; thus the demand curve slopes downward.

Along with organizations and individuals, there are some people who require loanable goods for hoarding purposes. Hoarding refers to the holding of some part of income by the individuals for future use. In hoarding, the supplier and buyer of loanable funds is the same person.

A person may want to hold funds when the rate of interest is low. On the contrary, he/she may use his/her funds by investing in new projects, when the rate of interest is high. Therefore, the demand of loanable funds is interest elastic for hoarding purpose; thus, the demand curve slopes downward.

Figure-20 shows the interaction between the demand and supply curve of loanable funds to reach at equilibrium position:

In Figure-20, DH represents dishoarding curve, BM is bank credit curve, S represents saving curve, and DI is disinvestment curve. LS represent the supply of loanable funds, which is produced by summing up the DH, BM, S, and DI curve. Similarly, H represents hoarding, C is consumption, and I is investment, which together form LD.

In Figure-20, LD is the demand for loanable funds. The point at which the demand and supply curve of loanable funds intersect each other is termed as equilibrium point (E). At point E, the rate of interest is OR with ON loanable funds. Therefore, OR would be the equilibrium rate of interest in the credit market.

“Other things remaining the same when a person takes successive units of a commodity, the marginal utility diminishes constantly”.

The marginal utility of a commodity diminishes at the consumer gets larger quantities of it. Marginal utility is the change in the total utility resulting from one unit change in the consumption of a commodity per unit of time.

Assumptions:

Following are the assumptions of the law of diminishing marginal utility.

1. The utility is measurable and a person can express the utility derived from a commodity in qualitative terms such as 2 units, 4 units and 7 units etc.
2. A rational consumer aims at the maximization of his utility.
3. It is necessary that a standard unit of measurement is constant
4. A commodity is being taken continuously. Any gap between the consumption of a commodity should be suitable.
5. There should be proper units of a good consumed by the consumer.
6. It is assumed that various units of commodity homogeneous in characteristics.
7. The taste of the consumer remains same during the consumption o the successive units of commodity.
8. Income of the consumer remains constant during the operation of the law of diminishing marginal utility.
9. It is assumed that the commodity is divisible.

• There should be not change in fashion. For example, if there is a fashion of lifted shirts, then the consumer may have no utility in open shirts.
• It is assumed that the prices of the substitutes do not change. For example, the demand for CNG increases due to rise in the prices of petroleum and these price changes effect the utility of CNG.

Explanation with Schedule and Diagram:

We assume that a man is very thirsty. He takes the glasses of water successively. The marginal utility of the successive glasses of water decreases, ultimately, he reaches the point of satiety. After this point the marginal utility becomes negative, if he is forced further to take a glass of water. The behavior of the consumer is indicated in the following schedule:

Units of commodity	Marginal utility	Total utility
1st glass	10	10
2nd glass	8	18
3rd glass	6	24
4th glass	4	28
5th glass	2	30
6th glass	0	30
7th glass	-2	28

On taking the 1st glass of water, the consumer gets 10 units of utility, because he is very thirsty. When he takes 2nd glass of water, his marginal utility goes down to 8 units because his thirst has been partly satisfied. This process continues until the marginal utility drops down to zero which is the saturation point. By taking the seventh glass of water, the marginal utility becomes negative because the thirst of the consumer has already been fully satisfied.

The law of diminishing marginal utility can be explained by the following diagram drawn with the help of above schedule:

In the above figure, the marginal utility of different glasses of water is measured on the y-axis and the units (glasses of water) on X-axis. With the help of the schedule, the points A, B, C, D, E, F and G are derived by the different combinations of units of the commodity (glasses of water) and the marginal utility gained by different units of commodity. By joining these points, we get the marginal utility curve. The marginal utility curve has the downward negative slope. It intersects the X-axis at the point of 6th unit of the commodity. At this point “F” the marginal utility becomes zero. When the MU curve goes beyond this point, the MU becomes negative. So there is an inverse functional relationship between the units of a commodity and the marginal utility of that commodity.

Limitations:

The limitations or exceptions of the law of diminishing marginal utility are as follows:

1. The law does not hold well in the rare collections. For example, collection of ancient coins, stamps etc.
2. The law is not fully applicable to money. The marginal utility of money declines with richness but never falls to zero.
3. It does not apply to the knowledge, art and innovations.
4. The law is not applicable for precious goods.
5. Historical things are also included in exceptions to the law.
6. Law does not operate if consumer behaves in irrational manner. For example, drunkard is said to enjoy each successive peg more than the previous one.
7. Man is fond of beauty and decoration. He gets more satisfaction by getting the above merits of the commodities.
8. If a dress comes in fashion, its utility goes up. On the other hand its utility goes down if it goes out of fashion.
9. The utility increases due to demonstration. It is a natural element.

Importance of the Law of Diminishing Marginal Utility:

The importance or the role of the law of diminishing marginal utility is as follows:

1. By purchasing more of a commodity the marginal utility decreases. Due to this behaviour, the consumer cuts his expenditures to that commodity.
2. In the field of public finance, this law has a practical application, imposing a heavier burden on the rich people.
3. This law is the base of some other economic laws such as law of demand, elasticity of demand, consumer surplus and the law of substitution etc.
4. The value of commodity falls by increasing the supply of a commodity. It forms a basis of the theory of value. In this way prices are determined

The Law of equi-marginal Utility is another fundamental principle of Econo­mics. This law is also known as the Law of substitution or the Law of Maxi­mum Satisfaction. We know that human wants are unlimited whereas the means to satisfy these wants are strictly limited. It, therefore’ becomes necessary to pick up the most urgent wants that can be satisfied with the money that a consumer has. Of the things that he decides to buy he must buy just the right quantity. Every prudent consumer will try to make the best use of the money at his disposal and derive the maximum satisfaction.

Explanation of the Law

In order to get maximum satisfaction out of the funds we have, we carefully weigh the satisfaction obtained from each rupee ‘had we spend If we find that a rupee spent in one direction has greater utility than in another, we shall go on spending money on the former commodity, till the satisfaction derived from the last rupee spent in the two cases is equal.

It other words, we substitute some units of the commodity of greater utility tor some units of the commodity of less utility. The result of this substitution will be that the marginal utility of the former will fall and that of the latter will rise, till the two marginal utilities are equalized. That is why the law is also called the Law of Substitution or the Law of equimarginal Utility.

Suppose apples and oranges are the two commodities to be purchased. Suppose further that we have got seven rupees to spend. Let us spend three rupees on oranges and four rupees on apples. What is the result? The utility of the 3rd unit of oranges is 6 and that of the 4th unit of apples is 2. As the marginal utility of oranges is higher, we should buy more of oranges and less of apples. Let us substitute one orange for one apple so that we buy four oranges and three apples.

Now the marginal utility of both oranges and apples is the same, i.e., 4. This arrangement yields maximum satisfaction. The total utility of 4 oranges would be 10 + 8 + 6 + 4 = 28 and of three apples 8 + 6 + 4= 18 which gives us a total utility of 46. The satisfaction given by 4 oranges and 3 apples at one rupee each is greater than could be obtained by any other combination of apples and oranges. In no other case does this utility amount to 46. We may take some other combinations and see.

We thus come to the conclusion that we obtain maximum satisfaction when we equalize marginal utilities by substituting some units of the more useful for the less useful commodity. We can illustrate this principle with the help of a diagram.

Diagrammatic Representation:

In the two figures given below, OX and OY are the two axes. On X-axis OX are represented the units of money and on the Y-axis marginal utilities. Suppose a person has 7 rupees to spend on apples and oranges whose diminishing marginal utilities are shown by the two curves AP and OR respectively.

The consumer will gain maximum satisfaction if he spends OM money (3 rupees) on apples and OM’ money (4 rupees) on oranges because in this situation the marginal utilities of the two are equal (PM = P’M’). Any other combination will give less total satisfaction.

Let the purchase spend MN money (one rupee) more on apples and the same amount of money, N’M'( = MN) less on oranges. The diagram shows a loss of utility represented by the shaded area LN’M’P’ and a gain of PMNE utility. As MN = N’M’ and PM=P’M’, it is proved that the area LN’M’P’ (loss of utility from reduced consumption of oranges) is bigger than PMNE (gain of utility from increased consumption of apples). Hence the total utility of this new combination is less.

We then, conclude that no other combination of apples and oranges gives as great a satisfaction to the consumer as when PM = P’M’, i.e., where the marginal utilities of apples and oranges purchased are equal, with given amour, of money at our disposal.

Limitations of the Law of Equimarginal Utility

Like other economic laws, the law of equimarginal utility too has certain limitations or exceptions. The following are the main exception.

(i) Ignorance

If the consumer is ignorant or blindly follows custom or fashion, he will make a wrong use of money. On account of his ignorance he may not know where the utility is greater and where less. Thus, ignorance may prevent him from making a rational use of money. Hence, his satisfaction may not be the maximum, because the marginal utilities from his expenditure can­not be equalised due to ignorance.

(ii) Inefficient Organisation

In the same manner, an incompetent organ­iser of business will fail to achieve the best results from the units of land, labour and capital that he employs. This is so because he may not be able to divert expenditure to more profitable channels from the less profitable ones.

(iii) Unlimited Resources

The law has obviously no place where this resources are unlimited, as for example, is the case with the free gifts of nature. In such cases, there is no need of diverting expenditure from one direction to another.

(iv) Hold of Custom and Fashion

A consumer may be in the strong clutches of custom, or is inclined to be a slave of fashion. In that case, he will not be able to derive maximum satisfaction out of his expenditure, because he cannot give up the consumption of such commodities. This is specially true of the conventional necessaries like dress or when a man is addicted to some into­xicant.

(v) Frequent Changes in Prices

Frequent changes in prices of different goods render the observance of the law very difficult. The consumer may not be able to make the necessary adjustments in his expenditure in a constantly changing price situation.

Consumer Surplus is the difference between the price that consumers pay and the price that they are willing to pay. On a supply and demand curve, it is the area between the equilibrium price and the demand curve

For example, if you would pay 76p for a cup of tea, but can buy it for 50p; your consumer surplus is 26p

Diagram of Consumer Surplus

Producer Surplus

• This is the difference between the price a firm receives and the price it would be willing to sell it at.
• Therefore it is the difference between the supply curve and the market price.

Consumer Surplus and Marginal Utility

The demand curve is derived from our marginal utility. If the marginal utility of a good is greater than the price, then that is our consumer surplus.

1. Firms can reduce consumer surplus if they have market power. This enables them to raise prices above the competitive equilibrium.
2. In a monopoly, a firm will maximise profits by reducing consumer surplus.
3. Another way to reduce consumer surplus is to engage in price discrimination. Charging different prices to different groups of consumers. Those with inelastic demand will see their consumer surplus reduced. More on Price discrimination. To completely eliminate consumer surplus, a firm would need to engage in first-degree price discrimination this means charging the consumer the highest price they are willing to pay.
4. To gain market power, a firm could advertise to create brand loyalty, this will make demand more inelastic

Significance of consumer surplus

• In competitive markets, firms have to keep prices relatively low, enabling consumers to gain consumer surplus. If markets were not competitive, the consumer surplus would be less and there would be greater inequality.
• A lower consumer surplus leads to higher producer surplus and greater inequality.
• Consumer surplus enables consumers to purchase a wider choice of goods.

Decision Support system (DSS) is a computerized program used to support determinations, judgments, and courses of action in an organization or a business. A DSS sifts through and analyzes massive amounts of data, compiling comprehensive information that can be used to solve problems and in decision-making.

Typical information used by a DSS includes target or projected revenue, sales figures or past ones from different time periods, and other inventory- or operations-related data.

A DSS can be used by operations management and planning levels in an organization to compile information and data and synthesize it into actionable intelligence. This allows the end user to make more informed decisions at a quicker pace.

The DSS is an information application that produces comprehensive information. This is different from an operations application, which would be used to collect the data in the first place. A DSS is primarily used by mid- to upper-level management, and it is key for understanding large amounts of data.

For example, a DSS could be used to project a company’s revenue over the upcoming six months based on new assumptions about product sales. Due to the large amount of variables that surround the projected revenue figures, this is not a straightforward calculation that can be done by hand. A DSS can integrate multiple variables and generate an outcome and alternate outcomes, all based on the company’s past product sales data and current variables.

The primary purpose of using a DSS is to present information to the customer in a way that is easy to understand. A DSS system is beneficial because it can be programed to generate many types of reports, all based on user specifications. A DSS can generate information and output it graphically, such as a bar chart that represents projected revenue, or as a written report.

As technology continues to advance, data analysis is no longer limited to large bulky mainframes. Since a DSS is essentially an application, it can be loaded on most computer systems, including laptops. Certain DSS applications are also available through mobile devices. The flexibility of the DSS is extremely beneficial for customers who travel frequently. This gives them the opportunity to be well-informed at all times, which in turn provides them with the ability to make the best decisions for their company and customers at any time.

Integrating DSS with existing systems may pose compatibility and integration challenges.

• Learning Curve:

Users may face a learning curve when adopting new DSS tools and interfaces.

• Maintenance Requirements:

Regular maintenance and updates are necessary to keep DSS effective and up-to-date.

Components of a DSS

(i) Database Management System (DBMS)

To solve a problem the necessary data may come from internal or external database. In an organization, internal data are generated by a system such as TPS and MIS. External data come from a variety of sources such as newspapers, online data services, databases (financial, marketing, human resources).

(ii) Model Management System

It stores and accesses models that managers use to make decisions. Such models are used for designing manufacturing facility, analyzing the financial health of an organization, forecasting demand of a product or service, etc.

(iii) Support Tools

Support tools like online help; pulls down menus, user interfaces, graphical analysis, error correction mechanism, facilitates the user interactions with the system.

Classification of DSS

There are several ways to classify DSS. Hoi Apple and Whinstone classifies DSS as follows:

(i) Text Oriented DSS

It contains textually represented information that could have a bearing on decision. It allows documents to be electronically created, revised and viewed as needed.

(ii) Database Oriented DSS

Database plays a major role here; it contains organized and highly structured data.

(iii) Spreadsheet Oriented DSS

It contains information in spread sheets that allows create, view, modify procedural knowledge and also instructs the system to execute self-contained instructions. The most popular tool is Excel and Lotus 1-2-3.

(iv) Solver Oriented DSS

It is based on a solver, which is an algorithm or procedure written for performing certain calculations and particular program type.

(v) Rules Oriented DSS

It follows certain procedures adopted as rules.

(vi) Rules Oriented DSS

Procedures are adopted in rules oriented DSS. Export system is the example.

(vii) Compound DSS

It is built by using two or more of the five structures explained above.

Types of DSS

(i) Status Inquiry System

It helps in taking operational, management level, or middle level management decisions, for example daily schedules of jobs to machines or machines to operators.

(ii) Data Analysis System

It needs comparative analysis and makes use of formula or an algorithm, for example cash flow analysis, inventory analysis etc.

(iii) Information Analysis System

In this system data is analyzed and the information report is generated. For example, sales analysis, accounts receivable systems, market analysis etc.

(iv) Accounting System

It keeps track of accounting and finance related information, for example, final account, accounts receivables, accounts payables, etc. that keep track of the major aspects of the business.

(v) Model Based System

Simulation models or optimization models used for decision-making are used infrequently and creates general guidelines for operation or management.
