Welfare Economics

Meaning of Welfare Economics:

Welfare economics in a branch which is primarily concern with promotion of welfare of the community as measured in the satisfaction derived from consumption of goods & service at the disposal of the community.

Nature and Scope of Welfare Economxics:

The nature and the scope of welfare economics can be understood from the fall facts.

1.    Economic & Non-economic Welfare: Welfare economics is, no doubt is concerned with economic welfare. But it is also concerned with non-economic welfare. So, welfare economics is concerned with economics & non-economic welfare
2.    Both Positive as well as normative Study Explains: Positive as well as normative study explains an economic Phenomenon & Normative Economics:

Eg; Positive economics explains why wealth in the community is unequally distributed, but normative economic would also comment whether the unequal distribution of wealth is desirable or not. The question of commenting of desirability falls under the preview of economics welfare. That means, welfare economics is a normative study. Further, positive economics formulates economics generalizations and it is concerned with economic polices.
3.    Individual Welfare As Well As Social Welfare: Welfare economics is concerned with the individual welfare as well as social welfare.

Individual welfare is generally, defined as the sum total of satisfaction derived by an individual from the consumption of economic goods of services and social welfare is defined as an aggregate of the utilities or satisfactions of all individual in the society.

Application of Welfare Economics


  1. Pricing: It may be noted that the pricing policy & output policy of the public sector undertaking must be such as to maximize the social welfare.
  2. Trade Policy on International Trade: Weather there should be free trade policy or policy of protection to maximize economic welfare of the people
  3. Policy regarding rationing of scope product to maximize social welfare.
  4. Policy regarding Monopoly V/s Competition: It may be noted that welfare economics is opposed to the monopoly & supports competition for the maximization of social welfare.
  5. Taxation Policy: It may be noted that direct taxes such as Income Tax & Wealth Tax is better than indirect taxations likes sales tax; excise duty for the maximization of social welfare
  6. National Income: It may be noted that welfare economist are able to demonstrate the close relationship between income & welfare of the community. They suggest that increase in National Income and the redistribution of National Income on a basis favorable to the poor will increase the welfare of the community.
  7. Socialist Ideology: Welfare economics provides a strong support to socialist Ideology which is intended to maximize social welfare.

Analyses of Welfare Economics:

According to Pigou’s “Economic welfare is that part of social welfare which can be directly or indirectly measured by monetary rod. According to him economic welfare implies the satisfaction or utility derived by an individual from the consumption of exchangeable goods & services.

Pigou measured economic welfare in terms of national income. He stated that, other things being equal, an increase in the national income tends to improve the economic welfare of the people in the society & vice versa. So, the problem of economic welfare is nothing but the problem of raising real national Income. For raising the real national income, production resources should be shifted, from less profitable ventures to more profitable ventures. It is the pay to the economic welfare of the society.

Criticism of Pigou’s Concept of Economic Welfare:

Pigou’s concept of economic welfare is criticized by Dr. Graaf on two grounds. First, money as a measure of welfare is neither accurate non satisfactory, because the value of money changes with variations in the price level. Secondly, economic welfare does not depend on exchangeable goods and services, because it is not possible to separate economic factors from non-economic factors so far as individual’s state of mind is concerned.

Pareto’s Analysis of Welfare Economics:

Introduction:

Vilifredo Pareto, an Italian economist, is said to be the founder of new welfare economist act an objective test of social welfare, pareto’s analysis is called paretein optimum, Pareto unanimity rule paretian criterion & social or general optimum.

Paretian Analysis:

Paretian have laid down the condition for maximizing social welfare or for achieving social optimum

Conditions of Paretian Optimum:

Paretein optinum is based on certain conditions, the conditions of paretian optimum are as follows:

  1. There should be optimum allocations of products: The allocation of products is optimal. If it is such as to make it impossible for any fairs of individual to exchange any.
  2. There must be optinum degree of specialization i.e., The marginal rate of transformation between any two goods must be the same for any pair of firms producing both of them.
  3. There must be optimum factor utilization i.e., there must optinum relationship between the factor & the product. The utilization of factor will be optimum. If the marginal rate of transformation between any factor and any product is the same for any two firms using the factor & producing the product.
  4. There must be optimum allocation of factors of product among the various uses. So, that the marginal production in each use is the same.
  5. There must be optinum direction of production: Goods must be produced in such condition that they not only conform to consumer’s preferences.
  6. There must be optinum allocation of factor unit’s time.
  7. There must be inter-temporal allocation of assets i.e., every firm must bring about an optimal allocation of factor inputs & product output over time.

Basic or Fundamental Theorems of Welfare Economics:

Introduction:

They are two basic or fundamentals theorems of welfare economics; they are called the 1st & 2nd fundamental theorems of welfare economics.

  1. First Fundamental Theorems of Welfare Economics: The first fundamental theorem states that the price system from a perfectly competitive economy includes selfish, individuals, independently maximizing their private well being, to bring the economy to a socially optimal state.

Its states that the prices increase in response to excessive demand & fall in responsive to excessive supply.

It recommends the use of competitive mechanism, i.e., the use of free market for optimizing the economic welfare of the people.

  1. Second fundamental therom of welfare economic: It states that, when the initial distribution of resources is very uneven and cannot contribute to maximization the economic welfare of the people, an alterative mechanism should be thought of this theorem suggests the following course of actions.

a)    Choose and a outcome which is economically efficient & which will contribute to maximization of economic welfare of the people.
b)    Re-allocation the initial allocation of resources & then, simply rely unpon the competitive mechanism,

Thus the second fundamental theorem of economic welfare tell that competitive mechanism with distribution of wealth will contribute to more efficient outcome & more welfare.

Assumptions:

These theorems are based on certain assumption. They are:

a)    The perfectly competitive economy, refered to in – the 2 fundamental theorems imples the following conditions:

a.    Mobile resources
b.    Many buyers & many sellers
c.    Homogenous goods
d.    Perfect information
e.    Costless entry & exit

b)    There is consumer sovereignty
c)    There are property right in each good
d)    If the initial allocation or distribution is not proper, here is re-distribution of resources or wealth.
e)    The goods are consumption goods
f)     These two fundamental theorems apply to individual dual markets, & not to the whole economy.
