Q.Which of the following pair types of unemployment constitutes the “Natural Rate of Unemployment”?
(A) Frictional and seasonal unemployment
(B) Disguised and involuntary unemployment
(C) Structural and frictional unemployment
(D) Cyclical and educated unemployment

A and R are both true economic statements, but R does not directly explain WHY A's definition of involuntary unemployment is as stated.

Assertion (A) correctly defines involuntary unemployment: it occurs when persons of working age who are willing and able to work at the going/current wage rate cannot find employment. This is the standard NCERT definition and is TRUE.

Reason (R) states that at full-employment equilibrium there is no involuntary unemployment. This is also a TRUE statement -- by definition, full employment is the situation where everyone willing to work at the prevailing wage is employed (only frictional/voluntary unemployment may exist).

…

The Natural Rate of Unemployment is the sum of frictional unemployment (short spells while workers search for/switch jobs) and structural unemployment (mismatch between workers' skills and available jobs), both of which exist even when the economy is at full employment.

Frictional unemployment arises temporarily when people are between jobs -- searching for new employment, changing jobs or entering the labour force for the first time. Structural unemployment arises from a mismatch between the skills workers possess and the skills employers demand, often due to technological change or shifts in the structure of the economy. Neither reflects a defi …

The Assertion is true, the Reason is true, but the Reason does not explain the Assertion — the correct choice is (B).

False — full employment does not mean zero unemployment.

Full employment is a situation in which all those who are able and willing to work at the prevailing wage rate get work — i.e., there is no involuntary unemployment. Even at full employment some frictional unemployment (people changing jobs) and voluntary unemployment (those not willing to work at the going wage) remain. Hence full employment is consistent with a positive natural …

When an able-bodied person chooses not to work at the prevailing wage, it is termed voluntary unemployment.

True — full employment means no involuntary unemployment, not zero unemployment.

Full employment is a situation in which everyone who is able and willing to work at the prevailing wage gets work — i.e., there is no involuntary unemployment. Even then, some frictional unemployment (people between jobs) and voluntary unemployment (those unwilling to work at the going wage) remain. Hence full employment is consistent with a positive natural rate of u …

Unemployment rate (%) = (Unemployed persons ÷ Labour force) × 100.

The rate of unemployment in an economy is measured as the percentage of the labour force (i.e., persons who are either working or seeking/available for work) that is unemployed (willing and able to work at the prevailing wage rate but unable to find work). Formally:

Unemployment Rate = (Number of unemployed persons / Total labour force) × 100

Seasonal unemployment occurs when workers in season-bound occupations have no work during the off-season of the year.

Certain economic activities, by their very nature, do not offer work throughout the year. Agriculture is the classic example in an economy like India's — farm labourers are in great demand during sowing and harvesting but have little or no work in between. Similarly, workers in ice-factories, holiday resorts, or crop-processing units may find themselves without work for part of the year. This recurring, predictable, season-linked joblessness is called seasonal unemployment. It is distinct from structural, cyclical, or disguised unemployment because it i …

Involuntary unemployment means being jobless despite being willing and able to work at the existing wage — the real cause lies in deficient aggregate demand for labour, not in the worker's own choice.

Involuntary unemployment arises when the aggregate demand for labour in an economy falls short of the aggregate supply of labour at the prevailing (often rigid) wage rate. Workers affected by this kind of unemployment are not voluntarily staying out of the labour market — they are actively seeking jobs, are qualified, and are willing to accept the market wage, yet cannot find employment simply because there are not enough job vacancies available.

Keynes emphasised that this form of unemployment is a demand-deficient phenomenon: when aggregate demand in the economy falls, firms cut back production and lay off workers. Even if these unemployed workers offer to work for a lower wage, firms may still not hire them, because the underlying problem is a lack of orders/demand for output rather than the wage rate itself. This is what distinguishes involuntary unemployment from: …

Employment is the use of a person's labour in production of goods or services in exchange for income, whether as a wage-earner or self-employed.

• Employment covers anyone who is gainfully engaged in producing goods or services, whether as a wage/salaried employee working for someone else, or as a self-employed person working on their own account or in a family enterprise.
• The key feature is that the work generates an income and contributes to the economy's production — it is this productive, income-generating engagement of labour that economists call employment. …
