Costs Flashcards
Theory of Production
an effort to explain the principles by which a business firm decides how much of each commodity that it should sell/it will produce, and how much of each kind of labour, raw material, fixed capital good, etc., that it employs
Fixed costs
a cost that does not change with an increase or decrease in the number of goods or services produced.
Fixed costs may include lease and rental payments, insurance, and interest payments.
Variable costs
Variable costs change based on the amount of output produced. Variable costs may include labor, commissions, and raw materials. Variable costs rise as production increases and fall as production decreases.
Main Sectors of an Economy
Primary, Secondary, Tertiary
Primary Sector
this involves the extraction of raw materials from the earth
e.g. Mining, Fishing, Quarrying, Forestry.
Secondary Sector
the operations of this sector involve the manipulation of the raw materials from the primary production operations.
e.g. Food processing, manufacturing, construction.
Tertiary Sector
the operations of this sector involve the provision of services.
e.g. health care, banking, insurance
Fixed Factors
Fixed factors are those that do not change as output is increased or decreased.
e.g. offices, factories, machinery, computer systems
Variable Factors
Variable factors are those that do change with output, which means more are employed when production increases, and less when production decreases.
e.g. labour, energy, and raw materials directly used in production.
Short Run- Law of Diminishing Returns operates in the short run.
The short run is a concept that states that, within a certain period in the future, at least one factor of production is fixed while others are variable. (unique to a firm, industry, etc)
Long Run
The long run is a period of time in which all factors of production are variable.
Decision Making in Short Run
Only operating decisions are made
e.g. the quantity of raw materials to buy, the number of workers to hire.
Decision Making in Long Run
Planning decisions are made
e.g. expansion and entering new markets
Law of Returns To Scale- The Law of Returns to Scale operates in the long run.
the change in output of a firm or industry that results from an increase in all inputs.
Economies of Scale
the benefits that accrue to a firm as a result of increasing its level of output.
