The use of indifference curves in handling societys problems

Use of indifference curves used in dealing with society's problems

In microeconomic theory, an indifference curve is a graph demonstrating different bundles of goods, each assessed to quantity, concerning that your consumer is indifferent. That is at each point on the curve, the consumer has no inclination for one bundle over another. In other words, all of them are equally preferred. One can send equivalently to each point on the curve as rendering the same level of power (satisfaction) for the consumer. Indifferent curves can be relevant in various situations by inspecting demands and personal preferences of consumers towards different combos of products. This analysis can the be employed in different circumstances including;

It can be used in identifying allocation of resources to production or sociable services. Companies and Administration can employ indifference curves of different consumers to analyze what consumers choose if faced with choice and limited resources. This is assessed by the marginal rate of substitution which indicates how much of one service or product is willing to give up to gain one device of another. Those products with low marginal rate of substitution seem to be to be preferred by consumers and hence government and/or businesses should produce more of such products.

i) ii)




In the above mentioned illustration, if there are limited resources, indifference curve (i) signifies that the consumer prefers product A to B since he is willing to stop more of B to gain a unit of any. The opposite holds true in Physique (ii). This means that that if resources are limited, development of the preferred good should be allocated more resources than the other good.

Indifference curves can also be applied by firms to decide what features in something consumers value most. By knowing what features consumers prefer most, companies are able to make decisions associated with what advancements in products are essential to customers. Companies will therefore make use of resources in advancements that add value to customers thus being effective and reliable in satisfying consumer needs.

i) ii)




In shape (i), in case a and B are characteristics in something, then consumers in number (i) will be preferring feature A to B and hence companies are better of improving attribute a to get more customers and to satisfy them. The contrary holds true in figure (ii).

iii) Indifference curves can also be used by authorities in its fiscal regulations. The slope of indifference curves can be used to evaluate those goods that customers value more and are unwilling to stop. When this happens, when prices of such goods rise, the federal government can subsidize such products so that consumers can continue to afford them. The same policy may also be applied in taxation where those products that are producing externalities are taxed more to discourage their use.

A i ii


In the above body, customers value product B into a since they give up more units of any to get fewer systems of A. In case there is a subsidy on the product that consumers value, the consumer moves from the lower indifference curve and would go to a higher indifference curve thus increasing value to consumers. The consumer along the way lowers the intake of the less preferred product.

iv) Indifference curves may also be used by firms and producers to judge the result of change in income and price of goods on ingestion habits. Substitution and income effects that can be examined through indifference curves shows how usage of any good will change with changes in income, price of the nice or prices of other goods. A drop in the price tag on one good with no compensating change in income or other prices produces both a substitution result and an income effect. The substitution result always escalates the consumption of the good whose price has fallen; the income effect may increase or lower it with regards to the type of good.

The above diagram shows what would happen to utilization of tea and turnips if there is taxation on tea or the price tag on tea was increased from 2. 5 to 4. This would lead to less tea being consumed and more turnips being used. A firm before it chooses to increase prices can reap the benefits of such analysis.

v) Indifference curves can also be applied in deciding pay for different individuals to give up their leisure for work.

i) ii)




In number i, the individual values leisure more than work while in shape ii, the individual beliefs work more than leisure. This indicates that an organization must pay specific i, additional money to make him quit his leisure than they are required to pay individual ii. Individual I can therefore cost more and work less time than specific ii.

Question two

The laws and regulations of comes back to scale States that as a firm in the long run increases the quantities of all factors employed, other activities being equal, the outcome may rise initially at a more quick rate than the pace of upsurge in inputs, then output may upsurge in the same proportion of input, and ultimately, output increases less proportionately.


Where Q stands for result, L for labor, and C for capital. The guidelines a, b, and c (the last mentioned two being the exponents) are believed from empirical data. This model suggests that as you change labour and capital, end result will change.

Technique of development is unchanged.

All systems of factors are homogeneous.

Returns are measured in physical conditions.

There are three phases of returns over time; the law of increasing earnings, the law of constant results, regulations of diminishing results.

The law of Increasing Dividends describes increasing returns to scale. You will find increasing comes back to scale whenever a given percentage increase in source will lead to a larger relative percentage upsurge in outcome; where proportionate change in end result is greater than proportionate change in inputs (factors). Over time, Creation Function Coefficient (PFC) is measured by the ratio of proportionate change in end result to proportionate change in suggestions.   Q/Q =   Q x F.

The process of increasing earnings cannot go on for ever. It is followed by constant returns to size. While expanding its level of creation, the firm slowly but surely exhausts the economies accountable for increasing comes back. Thereafter, constant returns arise when PFC coefficient is = 1, it will be constant comes back to scale.

As development is sustained, growing diseconomies of factors are encountered. When powerful diseconomies are attained by feeble economies of certain factors, lessening returns to range results. This happens when PFC (development function coefficient) < 1. factors behind decreasing results may be;

Though all physical factors are increased proportionately, group and management as a factor cannot be increased in equal proportion.

Business risk improves more than proportionately when size of production is enhanced. Entrepreneurial efficiency also has its restrictions.

Growing diseconomies of large-scale development set in when range of production rises beyond a limit.

Problem of supervision and coordination becomes intricate and intractable in a big scale operation and becomes unwieldy to manage

This legislation of returns to level can be applied in creation and allocation of resources in several sectors. When a business is growing all factors of development, the law is applicable and if enlargement goes on and on, reducing returns to scale will result. This gives the firm the ultimate position to produce in where more increase in factors will not result in increase in output.

The scientific physical relationship between inputs and outputs per device of time, is known as production function. The relationship between your inputs to the creation process and the producing output is detailed by a development function. The production function is the name given to the partnership between rates of suggestions of fruitful services and the pace of output of the product. It's the economist's summation of technical knowledge. The level of production depends upon technical conditions. When there is improvement in the approach of creation, increased output can be obtained even with the same (set) quantity of factors. However, at a given point of energy, there is merely one maximum degree of output that may be obtained with confirmed mixture of factors of production. This technical legislations which expresses the partnership between factor inputs and output is referred to as production function. That is applied by businesses to look for the best mixture of factors of creation so as to result in optimum returns.

Returns to range are important for determining how many firms will populate an industry. When increasing returns to scale can be found, one large firm will produce more cheaply than two small companies. Small companies will thus have a tendency to combine to increase earnings, and those that not merge will eventually fail. Alternatively, if a business has decreasing returns to range, a merger of two small businesses to create a large firm will cut output, increase average costs, and lower gains. In such market sectors, many small companies should exist rather than a few large organizations.
