Land utilisation

  LAND UTILIZATION  Land is a scarce resource, whose supply is fixed for all practical purposes. At the same time, the demand for land for various competing purposes is continuously increasing with the increase in human population and economic growth.Land use pattern at any given time is determined by several factors including size of human and livestock population, the demand pattern, the technology in use, the cultural traditions, the location and capability of land, institutional factors like ownership pattern and rights scale regulation. Major Types of Land Utilization in India : As in all other countries, land in India is put to various uses. The utilization of land depends upon physical factors like topography, soil and climate as well as upon human factors such as the density of population, duration of occupation of the area,land tenure and technical levels of the people.There are spatial and temporal difference in land utilization due to the continued interplay of phys...

CONCEPT OF COSTS

Concept of cost
Meaning : Cost refers to the expenditure incurred by a producer on the factor (land, Labour, capital) as well as non factor (raw material) inputs for a given amount of output of a commodity.

Types of costs 
a) Money costs -Money costs refers to the sum of all payments to the factors of production engaged in the production of that commodity . It is the cost which enters the records of accountants of a company.
b) Opportunity cost  - Opportunity cost is the forgone value of inputs measured in terms of currently available next best alternative that is sacrificed.
c) Explicit costs - Expenditure incurred by the producer on the purchase of input from the market is called explicit costs.
d) Implicit costs - Estimated expenditure on the use of self owned inputs is called implicit cost.
e)Selling costs - Selling costs refer to the expenditure incurred by the producer in order to promote sale of the commodity.
Expenditure on advertisement is selling cost
f) Short -run cost - Short run is a period of time during which some factors are fixed and some are variable. In short run , only the proportion of the input can be changed not the scale.
The short run costs are divided into two types in order to help production and cost analysis :
1) Fixed cost : The fixed costs of a firm are those costs that do not vary with the size of its output. These are the costs of fixed plant and equipment of the firm.
2) Variable cost : Variable costs are those cost which change with the changes in the volume of output. These costs are also called as prime costs . Wages, payments for raw material , for fuel , for taxes are variable cost.
3) Average costs - Average cost i, the cost per unit of output produced. It is also called unit cost of production.It consists of two factors ime average fixed cost and average variable cost.
                      AC=AFC+ AVC
AFC is computed by dividing the total fixed cost by total output .
AVC is computed by dividing the total variable cost by total output.
4)Total cost - The overall cost that is incurred in the process of production in the short run period is called total cost.It also consists of two factors i.e Total fixed cost and total variable cost.
TFC are costs incurred on factor inputs which cannot be changed during short period.
TVC are the costs incurred on the purchase of variable factors.These can change when the output changed .
4)Marginal cost - Marginal cost is the addition to total cost due to the addition of one unit of output. It is the change in total cost when an additional unit of output is produced.

Relation between marginal cost and average cost
a) Both MC and AC are calculated from total cost.
b) When AC is falling, the MC is lower than AC.
c) When AC is rising, MC lies above AC and rises faster than AC.
d) MC curve must cut AC at its maximum point.

Role of capitalism

ROLE OF CAPITALISM IN DEVELOPING ECONOMY Capitalism is that part of the economics where there is no role of government agencies. The sole supe power of capitalism is in the hands of private owners.

Tokenization

Tokenization  Tokenization is the process of turning sensitive data into non-sensitive data called "tokens" that can be used in a database or internal system without bringing it into scope.  •It can be used to secure sensitive data by replacing the original data with an unrelated value of the same length and format.  •The tokens are then sent to an organization’s internal systems for use, and the original data is stored in a secure token vault. •The purpose of tokenization is to swap out sensitive data—typically payment card or bank account numbers—with a randomized number in the same format but with no intrinsic value of its own. •Tokenization is the process of removing sensitive data from your business systems by replacing it with an undecipherable token and storing the original data in a secure cloud data vault.  Token will be unique for a combination of card, token requestor (i.e. the entity which accepts request from the customer for tokenisation of a card and p...

Wheat crisis

WHEAT CRISES  Introduction : •On may 4,the government lowered its wheat production for the crop year ending june.  •The production is expected to fall during warm weather condition on most part of wheat producing states of Punjab, Haryana, Madhya Pradesh,  Uttar Pradesh.  Decline in wheat production •Wheat production has seen a drop during winter. In last marketing year, the government had purchased from farmers.  •During the same time,  announcement came declaring 'unfolding war in Ukraine' which give rise ti acute food insecurity in countries . •After 5 straight years of bumper output of wheat,  unprecedented heat waves  causes substantial loss to the crop . Early summer affects the crop yields in the wheat producing states . Government procurement •A larger quantity of wheat was being bought by the traders at higher rate than the minimum support price.  •Private traders have been prompted to buy more wheat from farmers as the price of whe...
