. Labour is a commodity that is supplied by labourers in exchange for a wage paid by demanding firms. Because these labourers exist as parts of a social, institutional, or political system, labour economics is often regarded as a sociology or political science. Labour markets or job markets function through the interaction of workers and employers. Labour economics looks at the suppliers of labour services (workers) and the demanders of labour services (employers), and attempts to understand the resulting pattern of wages, employment, and income. These patterns exist because each individual in the market is presumed to make rational choices based on the information that they know regarding wage, desire to provide labour, and desire for leisure. Labour markets are normally geographically bounded, but the rise of the internet has brought about a 'planetary labour market' in some sectors. Labour is a measure of the work done by human beings. It is conventionally contrasted with other

Macroeconomics of labour markets

The labour market in macroeconomic theory shows that the supply of labour exceeds demand, which has been proven by salary growth that lags productivity growth. When labour supply exceeds demand, salary faces downward pressure due to an employer's ability to pick from a labour pool that exceeds the jobs pool. However, if the demand for labour is larger than the supply, salary increases, as employee have more bargaining power while employers have to compete for scarce labour. The

, self-employed people are counted as employed. The skills required in a labour force can vary from individual to individual, as well as from firm to firm. Some firms have specific skills they are interested in, limiting the labour force to certain criteria. A firm requiring specific skills will help determine the size of the market. Variables like employment level, unemployment level, labour force, and unfilled vacancies are called stock variables because they measure a quantity at a point in time. They can be contrasted with flow variables which measure a quantity over a duration of time. Changes in the labour force are due to flow variables such as natural population growth, net immigration, new entrants, and retirements. Changes in unemployment depend on inflows (non-employed people starting to look for jobs and employed people who lose their jobs that are looking for new ones) and outflows (people who find new employment and people who stop looking for employment). When looking at the overall macroeconomy, several types of unemployment have been identified, which can be separated into two categories of natural and unnatural unemployment. ''Natural Unemployment'' * Frictional unemployment – This reflects the fact that it takes time for people to find and settle into new jobs that they feel are appropriate for them and their skill set. Technological advancement often reduces frictional unemployment; for example, internet search engines have reduced the cost and time associated with locating employment or

. * Structural unemployment – the number of jobs available in an industry are not sufficient enough to provide jobs to all persons who are interested in working or qualified to work in that industry. This can be due to the changes in industries prevalent in a country or because wages for the industry are too high, causing people to want to supply their labour to that industry. * Natural rate of unemployment (also known as full employment) – This is the summation of frictional and structural unemployment, that excludes cyclical contributions of unemployment (e.g. recessions) and seasonal unemployment. It is the lowest rate of unemployment that a stable economy can expect to achieve, given that some frictional and structural unemployment is inevitable. Economists do not agree on the level of the natural rate, with estimates ranging from 1% to 5%, or on its meaning – some associate it with "non-accelerating

Neoclassical microeconomic model – Supply

Households are suppliers of labour. In microeconomic theory, people are assumed to be rational and seeking to maximize their

. In the labour market model, their utility function expresses trade-offs in preference between leisure time and income from time used for labour. However, they are constrained by the hours available to them. Let ''w'' denote the hourly wage, ''k'' denote total hours available for labour and leisure, ''L'' denote the chosen number of working hours, π denote income from non-labour sources, and ''A'' denote leisure hours chosen. The individual's problem is to maximise utility ''U'', which depends on total income available for spending on consumption and also depends on the time spent in leisure, subject to a time constraint, with respect to the choices of labour time and leisure time: :$\text \quad U\left(wL + \pi, A\right) \quad \text \quad L + A \le k.$ This is shown in the graph below, which illustrates the trade-off between allocating time to leisure activities and allocating it to income-generating activities. The linear constraint indicates that every additional hour of leisure undertaken requires the loss of an hour of labour and thus of the fixed amount of goods that that labour's income could purchase. Individuals must choose how much time to allocate to

labelled IC1. The curve indicates the combinations of leisure and work that will give the individual a specific level of utility. The point where the highest indifference curve is just tangent to the constraint line (point A), illustrates the optimum for this supplier of labour services. If consumption is measured by the value of income obtained, this diagram can be used to show a variety of interesting effects. This is because the absolute value of the slope of the budget constraint is the wage rate. The point of optimisation (point A) reflects the equivalency between the wage rate and the

''Effects of a wage increase''
If the wage rate increases, this individual's constraint line pivots up from X,Y1 to X,Y2. He/she can now purchase more goods and services.

''The Income and Substitution effects of a wage increase''

. This substitution effect is represented by the shift from point C to point B. The net impact of these two effects is shown by the shift from point A to point B. The relative magnitude of the two effects depends on the circumstances. In some cases, such as the one shown, the substitution effect is greater than the income effect (in which case more time will be allocated to working), but in other cases, the income effect will be greater than the substitution effect (in which case less time is allocated to working). The intuition behind this latter case is that the individual decides that the higher earnings on the previous amount of labour can be "spent" by purchasing more leisure.

''The Labour Supply curve''
If the substitution effect is greater than the income effect, an individual's supply of labour services will increase as the wage rate rises, which is represented by a positive slope in the labour supply curve (as at point E in the adjacent diagram, which exhibits a positive wage

). This positive relationship is increasing until point F, beyond which the income effect dominates the substitution effect and the individual starts to reduce the number of labour hours he supplies (point G) as wage increases; in other words, the wage elasticity is now negative. The direction of the slope may change more than once for some individuals, and the labour supply curve is different for different individuals. Other variables that affect the labour supply decision, and can be readily incorporated into the model, include taxation, welfare, work environment, and income as a

Neoclassical microeconomic model – Demand

A firm's labour demand is based on its marginal physical product of labour (MPPL). This is defined as the additional output (or physical product) that results from an increase of one unit of labour (or from an infinitesimal increase in labour). (See also

can be affected by financial capital flows within and between countries, and the degree of capital mobility within and between countries. According to neoclassical theory, over the relevant range of outputs, the marginal physical product of labour is declining (law of diminishing returns). That is, as more and more units of labour are employed, their additional output begins to decline. Additionally, although the MRP is a good way of expressing an employer's demand, other factors such as social group formation can the demand, as well as the labour supply. This constantly restructures exactly what a labour market is, and leads way to cause problems for theories of inflation.

Neoclassical microeconomic model – Equilibrium

''A firm's labour demand in the short run (D) and a horizontal supply curve (S)''
The marginal revenue product of labour can be used as the demand for labour curve for this firm in the short run. In competitive markets, a firm faces a perfectly elastic supply of labour which corresponds with the wage rate and the marginal resource cost of labour (W = SL = MFCL). In imperfect markets, the diagram would have to be adjusted because MFCL would then be equal to the wage rate divided by marginal costs. Because optimum resource allocation requires that marginal factor costs equal marginal revenue product, this firm would demand L units of labour as shown in the diagram. The demand for labour of this firm can be summed with the demand for labour of all other firms in the economy to obtain the aggregate demand for labour. Likewise, the supply curves of all the individual workers (mentioned above) can be summed to obtain the aggregate supply of labour. These

, differ greatly. There are various factors concerning this phenomenon. This includes the MRP of the worker. A doctor's MRP is far greater than that of the port cleaner. In addition, the barriers to becoming a doctor are far greater than that of becoming a port cleaner. To become a doctor takes a lot of education and training which is costly, and only those who excel in academia can succeed in becoming doctors. The port cleaner, however, requires relatively less training. The supply of doctors is therefore significantly less elastic than that of port cleaners. Demand is also inelastic as there is a high demand for doctors and medical care is a necessity, so the NHS will pay higher wage rates to attract the profession.

Monopsony

Some labour markets have a single employer and thus do not satisfy the perfect competition assumption of the neoclassical model above. The model of a monopsonistic labour market gives a lower quantity of employment and a lower equilibrium wage rate than does the competitive model.

Asymmetric information

In many real-life situations, the assumption of perfect information is unrealistic. An employer does not necessarily know how hard workers are working or how productive they are. This provides an incentive for workers to from providing their full effort, called

Another aspect of uncertainty results from the firm's imperfect knowledge about worker ability. If a firm is unsure about a worker's ability, it pays a wage assuming that the worker's ability is the average of similar workers. This wage under compensates high-ability workers which may drive them away from the labour market as well as at the same time attracting low-ability workers. Such a phenomenon, called

Personnel economics: hiring and incentives

At the micro level, one sub-discipline eliciting increased attention in recent decades is analysis of internal labour markets, that is, ''within'' firms (or other organisations), studied in personnel economics from the perspective of personnel management. By contrast, external labour markets "imply that workers move somewhat fluidly between firms and wages are determined by some aggregate process where firms do not have significant discretion over wage setting." The focus is on "how firms establish, maintain, and end employment relationships and on how firms provide incentives to employees," including models and empirical work on incentive systems and as constrained by

Gini coefficient In economics Economics () is the social science that studies how people interact with value; in particular, the Production (economics), production, distribution (economics), distribution, and Consumption (economics), consumption o ...

. This coefficient does not have a concrete meaning but is more used as a way to compare inequality across regions. The higher the Gini coefficient is calculated to be the larger inequality exists in a region. Over time, inequality has, on average, been increasing. This is due to numerous factors including labour supply and demand shifts as well as institutional changes in the labour market. On the shifts in labour supply and demand, factors include demand for skilled workers going up more than the supply of skilled workers and relative to unskilled workers as well as technological changes that increase productivity; all of these things cause wages to go up for skilled labour while unskilled worker wages stay the same or decline. As for the institutional changes, a decrease in union power and a declining real minimum wage, which both reduce unskilled workers wages, and tax cuts for the wealthy all increase the inequality gap between groups of earners. As for discrimination, it is the difference in pay that can be attributed to the demographic differences between people, such as gender, race, ethnicity, religion, sexual orientation, etc, even though these factors do not affect the productivity of the worker. Many regions and countries have enacted government policies to combat discrimination, including discrimination in the workplace. Discrimination can be modelled and measured in numerous ways. The oaxaca decomposition is a common method used to calculate the amount of discrimination that exists when wages differ between groups of people. This decomposition aims to calculate the difference in wages that occurs because of differences in skills versus the returns to those skills. A way of modelling discrimination in the workplace when dealing with wages are

's taste models. Using taste models, employer discrimination can be thought of as the employer not hiring the minority worker because of their perceived cost of hiring that worker is higher than that of the cost of hiring a non-minority worker, which causes less hiring of the minority. Another taste model is for employee discrimination, which does not cause a decline in the hiring of minorities, but instead causes a more segregated workforce because the prejudiced worker feels that they should be paid more to work next to the worker they are prejudiced against or that they are not paid an equal amount as the worker they are prejudiced against. One more taste model involves customer discrimination, whereby the employers themselves are not prejudiced but believe that their customers might be, so therefore the employer is less likely to hire the minority worker if they are going to interact with customers that are prejudiced. There are many other taste models other than these that Gary Becker has made to explain discrimination that causes differences in hiring in wages in the labour market.

etc. Also missing from most labour market analyses is the role of unpaid labour such as unpaid internships where workers with little or no experience are allowed to work a job without pay so that they can gain experience in a particular profession. Even though this type of labour is unpaid it can nevertheless play an important part in society if not abused by employers. The most dramatic example is child raising. However, over the past 25 years an increasing literature, usually designated as the economics of the family, has sought to study within household decision making, including joint labour supply, fertility, child-raising, as well as other areas of what is generally referred to as home production.

explained how "whatever does not spring from a man's free choice, or is only the result of instruction and guidance, does not enter into his very nature; he does not perform it with truly human energies, but merely with mechanical exactness" and so when the labourer works under external control, "we may admire what he does, but we despise what he is." Both the Milgram and Stanford experiments have been found useful in the psychological study of wage-based workplace relations. The

. "It can be persuasively argued," noted one concerned philosopher, "that the conception of the worker's labour as a commodity confirms Marx's stigmatisation of the wage system of private capitalism as 'wage-slavery;' that is, as an instrument of the capitalist's for reducing the worker's condition to that of a slave, if not below it.". This Marxist objection is what motivated Nelson's essay, which claims that labour is not, in fact, a commodity.
