Pro­duc­tion is the process by which dif­fer­ent inputs, includ­ing cap­i­tal, labor, and land, are used to cre­ate out­puts in the form of prod­ucts or ser­vices.

Impor­tance of Pro­duc­tion is as fol­low:

  • Helps in cre­at­ing value by apply­ing labour on land and cap­i­tal
  • Improves wel­fare as more com­modi­ties mean more util­ity
  • Gen­er­ates employ­ment and income, which devel­ops the econ­omy.
  • Helps in under­stand­ing the rela­tion between cost and out­put

Pro­duc­tion Func­tion (PF) is a con­cept in eco­nom­ics that explains the rela­tion­ship between phys­i­cal out­put and input. Out­put refers to the num­ber of goods or ser­vices pro­duced in a given time period. Input, on the other hand, is the num­ber of resources or mate­ri­als that are used to pro­duce out­put. While pro­duc­tion is sim­ply the process of cre­at­ing goods and ser­vices for con­sump­tion, pro­duc­tion func­tion is the con­cept explain­ing the quan­ti­ta­tive rela­tion­ship between input and out­put. There are four main com­po­nents of the pro­duc­tion func­tion. Four main fac­tors of pro­duc­tion exist: land, labour, cap­i­tal, and entre­pre­neur­ship.

The land is the tan­gi­ble nat­ural resource that the com­pany uses to make its prod­ucts. The term 'land' does not only cor­re­spond to the land area but rep­re­sents the over­all nat­ural resources, such as rivers, and forests, which are used by busi­nesses. For this rea­son, the land is also referred to as a nat­ural fac­tor of pro­duc­tion.

Land is the gift of nature and includes the dry sur­face of the earth and the nat­ural resources on or under the earth’s sur­face, such as forests, rivers, sun­light, etc.

Land is utilised to pro­duce income called rent. Land is avail­able in fixed quan­tity; thus, does not have a sup­ply price. This implies that the change in price of land does not affect its sup­ply. The return for land is called rent.

Char­ac­ter­is­tics which would qual­ify a given fac­tor to be called land are,

  • Land is a free gift of nature.
  • Land is per­ma­nent and has inde­struc­tible pow­ers.
  • Land is a pas­sive fac­tor.
  • Land is immo­bile.
  • Land has mul­ti­ple uses.
  • Land is het­ero­ge­neous.

Labor­ers are humans who employ both their phys­i­cal and men­tal capa­bil­i­ties to con­tribute to the process of pro­duc­ing a prod­uct or a ser­vice. Labor is oth­er­wise known as the human fac­tor of pro­duc­tion.

Labour is the phys­i­cal and men­tal efforts of human beings that under­take the pro­duc­tion process.

It includes unskilled, semi-skilled and highly skilled labour. The sup­ply of labour is affected by the change in its prices. It increases with an increase in wages. The return for labour is called wages and salary.

Char­ac­ter­is­tics of labour

  • Human Effort.
  • Labour is per­ish­able.
  • Labour is an active fac­tor.
  • Labour is insep­a­ra­ble from the labourer.
  • Labour power dif­fers from labourer to labourer.
  • All labour may not be pro­duc­tive.
  • Labour has poor bar­gain­ing power.
  • Labour is mobile.
  • There is no rapid adjust­ment of sup­ply of labour to the demand for it.
  • Choice between hours of labour and hours of leisure.

Addi­tion­ally, any busi­ness needs a fac­tory or dif­fer­ent equip­ment to oper­ate. Cap­i­tal refers to these arti­fi­cial resources that are uti­lized in the pro­duc­tion process.

Cap­i­tal is the wealth cre­ated by human beings. It is one of the impor­tant fac­tor of pro­duc­tion of any kind of goods and ser­vices, as pro­duc­tion can­not take place with­out the involve­ment of cap­i­tal.

Cap­i­tal is an out­put of a pro­duc­tion process that goes into another pro­duc­tion process as an input. Cap­i­tal as a fac­tor of pro­duc­tion is divided into two parts, namely, phys­i­cal cap­i­tal and human cap­i­tal.

Phys­i­cal cap­i­tal includes tan­gi­ble resources, such as build­ings, machines, tools and equip­ment, etc.

Human cap­i­tal (HC) includes knowl­edge and skills of human resource, which is gained by edu­ca­tion, train­ing and expe­ri­ence. Return for cap­i­tal is termed as inter­est.

Types of Cap­i­tal

  • Fixed cap­i­tal
  • Cir­cu­lat­ing cap­i­tal
  • Real cap­i­tal
  • Human cap­i­tal
  • Tan­gi­ble cap­i­tal
  • Indi­vid­ual cap­i­tal
  • Social Cap­i­tal

Lastly, an entre­pre­neur is some­one who com­bines all of the resources - land, labor, and cap­i­tal to pro­duce a prod­uct or ser­vice. Entre­pre­neurs make deci­sions regard­ing the pro­duc­tion process and the best way to uti­lize the fac­tors of pro­duc­tion.

Entre­pre­neur­ship con­sists of three major func­tions, viz., coor­di­na­tion, man­age­ment and super­vi­sion. An entre­pre­neur is a per­son who cre­ates an enter­prise. The suc­cess or fail­ure depends on the effi­ciency of the entre­pre­neur.

An enter­prise is an organ­i­sa­tion that under­takes com­mer­cial pur­poses or busi­ness ven­tures and focuses on pro­vid­ing goods and ser­vices. An enter­prise is com­posed of indi­vid­u­als and phys­i­cal assets with a com­mon goal of gen­er­at­ing prof­its.

Func­tions of an entre­pre­neur

  • Ini­ti­at­ing busi­ness enter­prise and resource co-ordi­na­tion.
  • Risk bear­ing or uncer­tainty bear­ing.
  • Inno­va­tions.

In the long run, firms can change all the inputs to max­i­mize their prof­its, but in the short run, they are unable to change some of the inputs. Let's get straight into the short-term sit­u­a­tion when a firm is capa­ble of chang­ing only one input in its pro­duc­tion process.

  • There are two types of fac­tors of pro­duc­tion: Fixed fac­tors and Vari­able fac­tors.
  • Fixed fac­tors refer to those aspects of pro­duc­tion that remain the same regard­less of changes in the out­put.
  • Vari­able fac­tors are those that may change as out­put changes.
  • The for­mula for pro­duc­tion func­tion is Q= f(K, L), where Q is the out­put, f refers to func­tion, K is the cap­i­tal and L stands for labour.
  • There are two kinds of pro­duc­tion func­tions: Long Run and Short Run Pro­duc­tion Func­tion.

Key terms

Pro­duc­tion Func­tion (PF)
In eco­nom­ics, a pro­duc­tion func­tion gives the tech­no­log­i­cal rela­tion between quan­ti­ties of phys­i­cal inputs and quan­ti­ties of out­put of goods.

Com­mon ques­tions

What is a pro­duc­tion func­tion?

A pro­duc­tion func­tion is defined as a func­tion that rep­re­sents the quan­tity of out­put a firm can pro­duce given a cer­tain quan­tity of input com­bi­na­tion.

What is the impor­tance of pro­duc­tion func­tion?

It shows the rela­tion between input and out­put. It helps firms esti­mate their over­all pro­duc­tion and plan accord­ingly.

What is meant by the law of dimin­ish­ing returns?

The short-run pro­duc­tion func­tion adheres to the law of dimin­ish­ing mar­ginal returns. As more units of the vari­able input are added, the addi­tional out­put will even­tu­ally decrease due to the con­straint of fixed inputs.
