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.
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. 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 shirk from providing their full effort — since it is difficult for the employer to identify the hard-working and the shirking employees, there is no incentive to work hard and productivity falls overall, leading to the hiring of more workers and a lower unemployment rate.
One solution used recently [ when? However, this solution has attracted criticism as executives with large stock-option packages have been suspected of acting to over-inflate share values to the detriment of the long-run welfare of the firm. Another solution, foreshadowed by the rise of temporary workers in Japan and the firing of many of these workers in response to the financial crisis of , is more flexible job- contracts and -terms that encourage employees to work less than full-time by partially compensating for the loss of hours, relying on workers to adapt their working time in response to job requirements and economic conditions instead of the employer trying to determine how much work is needed to complete a given task and overestimating.
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 undercompensates high-ability workers and may drive them away from the labour market. Such a phenomenon, called adverse selection , can sometimes lead to market collapse.
There are many ways to overcome adverse selection in labour market. One important mechanism is called signalling , pioneered by Michael Spence. Employers can then use education as a signal to infer worker ability and pay higher wages to better-educated workers. It may appear to an external observer that education has raised the marginal product of labour, without this necessarily being true.

One of the major research achievements of the period was the development of a framework with dynamic search , matching, and bargaining. 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.
Many sociologists, political economists, and heterodox economists claim that labour economics tends to lose sight of the complexity of individual employment decisions. From the perspective of mainstream economics , neoclassical models are not meant to serve as a full description of the psychological and subjective factors that go into a given individual's employment relations, but as a useful approximation of human behaviour in the aggregate, which can be fleshed out further by the use of concepts such as information asymmetry , transaction costs , contract theory 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. The labour market, as institutionalised under today's market economic systems, has been criticised,  especially by both mainstream socialists and anarcho-syndicalists ,     who utilise the term wage slavery   as a pejorative for wage labour.
Socialists draw parallels between the trade of labour as a commodity and slavery. Cicero is also known to have suggested such parallels. According to Noam Chomsky , analysis of the psychological implications of wage slavery goes back to the Enlightenment era. In his book On the Limits of State Action , classical liberal thinker Wilhelm von Humboldt 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.
The American philosopher John Dewey posited that until " industrial feudalism " is replaced by "industrial democracy ," politics will be "the shadow cast on society by big business". As per anthropologist David Graeber , the earliest wage labour contracts we know about were in fact contracts for the rental of chattel slaves usually the owner would receive a share of the money, and the slave, another, with which to maintain his or her living expenses.
Such arrangements, according to Graeber, were quite common in New World slavery as well, whether in the United States or Brazil. James argued that most of the techniques of human organisation employed on factory workers during the industrial revolution were first developed on slave plantations. Additionally, Marxists posit that labour-as-commodity, which is how they regard wage labour,  provides an absolutely fundamental point of attack against capitalism.

Its namesake economist John Maynard Keynes , believed that the root cause of unemployment is the desire of investors to receive more money rather than produce more products, which is not possible without public bodies producing new money.
In addition to these comprehensive theories of unemployment, there are a few categorizations of unemployment that are used to more precisely model the effects of unemployment within the economic system. Some of the main types of unemployment include structural unemployment and frictional unemployment , as well as cyclical unemployment , involuntary unemployment , and classical unemployment. Structural unemployment focuses on foundational problems in the economy and inefficiencies inherent in labor markets, including a mismatch between the supply and demand of laborers with necessary skill sets.
Structural arguments emphasize causes and solutions related to disruptive technologies and globalization. Discussions of frictional unemployment focus on voluntary decisions to work based on each individuals' valuation of their own work and how that compares to current wage rates plus the time and effort required to find a job.
Causes and solutions for frictional unemployment often address job entry threshold and wage rates. The state of being without any work for an educated person, for earning one's livelihood is meant by unemployment. Economists distinguish between various overlapping types of and theories of unemployment, including cyclical or Keynesian unemployment , frictional unemployment , structural unemployment and classical unemployment. Some additional types of unemployment that are occasionally mentioned are seasonal unemployment, hardcore unemployment, and hidden unemployment.
Though there have been several definitions of "voluntary" and " involuntary unemployment " in the economics literature, a simple distinction is often applied. Voluntary unemployment is attributed to the individual's decisions, whereas involuntary unemployment exists because of the socio-economic environment including the market structure, government intervention, and the level of aggregate demand in which individuals operate. In these terms, much or most of frictional unemployment is voluntary, since it reflects individual search behavior. Voluntary unemployment includes workers who reject low wage jobs whereas involuntary unemployment includes workers fired due to an economic crisis, industrial decline , company bankruptcy, or organizational restructuring.
On the other hand, cyclical unemployment, structural unemployment, and classical unemployment are largely involuntary in nature. However, the existence of structural unemployment may reflect choices made by the unemployed in the past, while classical natural unemployment may result from the legislative and economic choices made by labour unions or political parties. So, in practice, the distinction between voluntary and involuntary unemployment is hard to draw. The clearest cases of involuntary unemployment are those where there are fewer job vacancies than unemployed workers even when wages are allowed to adjust, so that even if all vacancies were to be filled, some unemployed workers would still remain.
This happens with cyclical unemployment, as macroeconomic forces cause microeconomic unemployment which can boomerang back and exacerbate these macroeconomic forces. Classical, or real-wage unemployment, occurs when real wages for a job are set above the market-clearing level causing the number of job-seekers to exceed the number of vacancies.
On the other hand, most economists argue that as wages fall below a livable wage many choose to fall out of the labor market and no longer seek employment. This is especially true in countries where low-income families are supported through public welfare systems. In such cases, wages would have to be high enough to motivate people to choose employment over what they receive through public welfare. Wages below a livable wage are likely to result in lower labor market participation in above stated scenario.
In addition, it must be noted that consumption of goods and services is the primary driver of increased need for labor. Higher wages lead to workers having more income available to consume goods and services. Therefore, higher wages increase general consumption and as a result need for labor increases and unemployment decreases in the economy. Many economists have argued that unemployment increases with increased governmental regulation. For example, minimum wage laws raise the cost of some low-skill laborers above market equilibrium, resulting in increased unemployment as people who wish to work at the going rate cannot as the new and higher enforced wage is now greater than the value of their labour.
However, this argument overly simplifies the relationship between wage rates and unemployment, ignoring numerous factors, which contribute to unemployment. In Out of Work: Unemployment and Government in the Twentieth-Century America , economists Richard Vedder and Lowell Gallaway argue that the empirical record of wages rates, productivity, and unemployment in American validates classical unemployment theory. Their data shows a strong correlation between adjusted real wage and unemployment in the United States from to However, they maintain that their data does not take into account exogenous events.
Cyclical, deficient-demand, or Keynesian unemployment, occurs when there is not enough aggregate demand in the economy to provide jobs for everyone who wants to work. Demand for most goods and services falls, less production is needed and consequently fewer workers are needed, wages are sticky and do not fall to meet the equilibrium level, and mass unemployment results.
With cyclical unemployment, the number of unemployed workers exceeds the number of job vacancies, so that even if full employment were attained and all open jobs were filled, some workers would still remain unemployed. Some associate cyclical unemployment with frictional unemployment because the factors that cause the friction are partially caused by cyclical variables. For example, a surprise decrease in the money supply may shock rational economic factors and suddenly inhibit aggregate demand. Keynesian economists on the other hand see the lack of supply for jobs as potentially resolvable by government intervention.
One suggested interventions involves deficit spending to boost employment and demand. Another intervention involves an expansionary monetary policy that increases the supply of money which should reduce interest rates which should lead to an increase in non-governmental spending. It is in the very nature of the capitalist mode of production to overwork some workers while keeping the rest as a reserve army of unemployed paupers. Marxists share the Keynesian viewpoint of the relationship between economic demand and employment, but with the caveat that the market system's propensity to slash wages and reduce labor participation on an enterprise level causes a requisite decrease in aggregate demand in the economy as a whole, causing crises of unemployment and periods of low economic activity before the capital accumulation investment phase of economic growth can continue.
According to Karl Marx , unemployment is inherent within the unstable capitalist system and periodic crises of mass unemployment are to be expected. He theorized that unemployment was inevitable and even a necessary part of the capitalist system, with recovery and regrowth also part of the process. This is accomplished by dividing the proletariat into surplus labour employees and under-employment unemployed.
At first glance, unemployment seems inefficient since unemployed workers do not increase profits, but unemployment is profitable within the global capitalist system because unemployment lowers wages which are costs from the perspective of the owners. From this perspective low wages benefit the system by reducing economic rents.
Yet, it does not benefit workers; according to Karl Marx, the workers proletariat work to benefit the bourgeoisie through their production of capital . Capitalist systems unfairly manipulate the market for labour by perpetuating unemployment which lowers laborers' demands for fair wages.
Workers are pitted against one another at the service of increasing profits for owners. As a result of the capitalist mode of production, Marx argued that workers experienced alienation and estrangement through their economic identity. According to Marx, the only way to permanently eliminate unemployment would be to abolish capitalism and the system of forced competition for wages and then shift to a socialist or communist economic system.
For contemporary Marxists, the existence of persistent unemployment is proof of the inability of capitalism to ensure full employment. In demand-based theory, it is possible to abolish cyclical unemployment by increasing the aggregate demand for products and workers.
However, eventually the economy hits an " inflation barrier" imposed by the four other kinds of unemployment to the extent that they exist. Historical experience suggests that low unemployment affects inflation in the short term but not the long term. Some demand theory economists see the inflation barrier as corresponding to the natural rate of unemployment.
The "natural" rate of unemployment is defined as the rate of unemployment that exists when the labour market is in equilibrium and there is pressure for neither rising inflation rates nor falling inflation rates. No matter what its name, demand theory holds that this means that if the unemployment rate gets "too low," inflation will accelerate in the absence of wage and price controls incomes policies. Another, normative, definition of full employment might be called the ideal unemployment rate.
It would exclude all types of unemployment that represent forms of inefficiency. This type of "full employment" unemployment would correspond to only frictional unemployment excluding that part encouraging the McJobs management strategy and would thus be very low. However, it would be impossible to attain this full-employment target using only demand-side Keynesian stimulus without getting below the NAIRU and causing accelerating inflation absent incomes policies.
Training programs aimed at fighting structural unemployment would help here. To the extent that hidden unemployment exists, it implies that official unemployment statistics provide a poor guide to what unemployment rate coincides with "full employment". Structural unemployment occurs when a labour market is unable to provide jobs for everyone who wants one because there is a mismatch between the skills of the unemployed workers and the skills needed for the available jobs.
Structural unemployment is hard to separate empirically from frictional unemployment, except to say that it lasts longer. As with frictional unemployment, simple demand-side stimulus will not work to easily abolish this type of unemployment. Structural unemployment may also be encouraged to rise by persistent cyclical unemployment: Problems with debt may lead to homelessness and a fall into the vicious circle of poverty.
This means that they may not fit the job vacancies that are created when the economy recovers. The implication is that sustained high demand may lower structural unemployment. This theory of persistence in structural unemployment has been referred to as an example of path dependence or "hysteresis". Much technological unemployment ,  due to the replacement of workers by machines, might be counted as structural unemployment. Alternatively, technological unemployment might refer to the way in which steady increases in labour productivity mean that fewer workers are needed to produce the same level of output every year.
The fact that aggregate demand can be raised to deal with this problem suggests that this problem is instead one of cyclical unemployment. As indicated by Okun's Law , the demand side must grow sufficiently quickly to absorb not only the growing labour force but also the workers made redundant by increased labour productivity. Seasonal unemployment may be seen as a kind of structural unemployment, since it is a type of unemployment that is linked to certain kinds of jobs construction work, migratory farm work.
The most-cited official unemployment measures erase this kind of unemployment from the statistics using "seasonal adjustment" techniques. This results in substantial, permanent structural unemployment. Frictional unemployment is the time period between jobs when a worker is searching for, or transitioning from one job to another. It is sometimes called search unemployment and can be voluntary based on the circumstances of the unemployed individual. Frictional unemployment exists because both jobs and workers are heterogeneous , and a mismatch can result between the characteristics of supply and demand.
Such a mismatch can be related to skills, payment, work-time, location, seasonal industries, attitude, taste, and a multitude of other factors. New entrants such as graduating students and re-entrants such as former homemakers can also suffer a spell of frictional unemployment. Workers as well as employers accept a certain level of imperfection, risk or compromise, but usually not right away; they will invest some time and effort to find a better match.
This is in fact beneficial to the economy since it results in a better allocation of resources. However, if the search takes too long and mismatches are too frequent, the economy suffers, since some work will not get done. Therefore, governments will seek ways to reduce unnecessary frictional unemployment through multiple means including providing education, advice, training, and assistance such as daycare centers. The frictions in the labour market are sometimes illustrated graphically with a Beveridge curve , a downward-sloping, convex curve that shows a correlation between the unemployment rate on one axis and the vacancy rate on the other.
Changes in the supply of or demand for labour cause movements along this curve. An increase decrease in labour market frictions will shift the curve outwards inwards. Hidden, or covered, unemployment is the unemployment of potential workers that are not reflected in official unemployment statistics, due to the way the statistics are collected. Those who have given up looking for work and sometimes those who are on Government "retraining" programs are not officially counted among the unemployed, even though they are not employed. The statistic also does not count the " underemployed "—those working fewer hours than they would prefer or in a job that doesn't make good use of their capabilities.
In addition, those who are of working age but are currently in full-time education are usually not considered unemployed in government statistics. Traditional unemployed native societies who survive by gathering, hunting, herding, and farming in wilderness areas, may or may not be counted in unemployment statistics. Official statistics often underestimate unemployment rates because of hidden unemployment.
Long-term unemployment is defined in European Union statistics, as unemployment lasting for longer than one year. Long-term unemployment is a component of structural unemployment , which results in long-term unemployment existing in every social group, industry, occupation, and all levels of education. There are also different ways national statistical agencies measure unemployment.
These differences may limit the validity of international comparisons of unemployment data. Though many people care about the number of unemployed individuals, economists typically focus on the unemployment rate. This corrects for the normal increase in the number of people employed due to increases in population and increases in the labour force relative to the population. The unemployment rate is expressed as a percentage , and is calculated as follows:.
As defined by the International Labour Organization , "unemployed workers" are those who are currently not working but are willing and able to work for pay, currently available to work, and have actively searched for work. Simply looking at advertisements and not responding will not count as actively seeking job placement. Since not all unemployment may be "open" and counted by government agencies, official statistics on unemployment may not be accurate. The ILO describes 4 different methods to calculate the unemployment rate: The primary measure of unemployment, U3, allows for comparisons between countries.
Unemployment differs from country to country and across different time periods. For example, during the s and s, the United States had lower unemployment levels than many countries in the European Union ,  which had significant internal variation, with countries like the UK and Denmark outperforming Italy and France.
However, large economic events such as the Great Depression can lead to similar unemployment rates across the globe. Eurostat , the statistical office of the European Union , defines unemployed as those persons age 15 to 74 who are not working, have looked for work in the last four weeks, and ready to start work within two weeks, which conform to ILO standards.
Both the actual count and rate of unemployment are reported.
Statistical data are available by member state, for the European Union as a whole EU28 as well as for the euro area EA Eurostat also includes a long-term unemployment rate. This is defined as part of the unemployed who have been unemployed for an excess of 1 year.

For monthly calculations, national surveys or national registers from employment offices are used in conjunction with quarterly EU-LFS data. The exact calculation for individual countries, resulting in harmonized monthly data, depends on the availability of the data.

This Survey measures the unemployment rate based on the ILO definition. The Current Employment Statistics survey CES , or "Payroll Survey", conducts a survey based on a sample of , businesses and government agencies that represent , individual employers. These two sources have different classification criteria, and usually produce differing results.
Additional data are also available from the government, such as the unemployment insurance weekly claims report available from the Office of Workforce Security, within the U. The Bureau of Labor Statistics also calculates six alternate measures of unemployment, U1 through U6, that measure different aspects of unemployment: Statistics for the U. For example, in January U.
The unemployment rate is included in a number of major economic indexes including the United States' Conference Board's Index of Leading Indicators a macroeconomic measure of the state of the economy. Some critics believe that current methods of measuring unemployment are inaccurate in terms of the impact of unemployment on people as these methods do not take into account the 1.
These last people are "involuntary part-time" workers, those who are underemployed, e.
Internationally, some nations' unemployment rates are sometimes muted or appear less severe due to the number of self-employed individuals working in agriculture. Many economies industrialize and experience increasing numbers of non-agricultural workers. When comparing unemployment rates between countries or time periods, it is best to consider differences in their levels of industrialization and self-employment. Additionally, the measures of employment and unemployment may be "too high".
In some countries, the availability of unemployment benefits can inflate statistics since they give an incentive to register as unemployed. People who do not seek work may choose to declare themselves unemployed so as to get benefits; people with undeclared paid occupations may try to get unemployment benefits in addition to the money they earn from their work.

However, in countries such as the United States, Canada, Mexico, Australia, Japan and the European Union, unemployment is measured using a sample survey akin to a Gallup poll. The sample survey has its own problems because the total number of workers in the economy is calculated based on a sample rather than a census. It is possible to be neither employed nor unemployed by ILO definitions, i. Many of these people are going to school or are retired. Family responsibilities keep others out of the labour force.
Still others have a physical or mental disability which prevents them from participating in labour force activities. Some people simply elect not to work preferring to be dependent on others for sustenance. Typically, employment and the labour force include only work done for monetary gain. Hence, a homemaker is neither part of the labour force nor unemployed. Nor are full-time students nor prisoners considered to be part of the labour force or unemployment.
In , economists Lawrence F. Katz and Alan B. Krueger estimated that increased incarceration lowered measured unemployment in the United States by 0. In particular, as of , roughly 0. Additionally, children, the elderly, and some individuals with disabilities are typically not counted as part of the labour force in and are correspondingly not included in the unemployment statistics.
However, some elderly and many disabled individuals are active in the labour market. In the early stages of an economic boom , unemployment often rises. Similarly, during a recession , the increase in the unemployment rate is moderated by people leaving the labour force or being otherwise discounted from the labour force, such as with the self-employed. At the same time and for the same population the employment rate number of workers divided by population was Due to these deficiencies, many labour market economists prefer to look at a range of economic statistics such as labour market participation rate, the percentage of people aged between 15 and 64 who are currently employed or searching for employment, the total number of full-time jobs in an economy, the number of people seeking work as a raw number and not a percentage, and the total number of person-hours worked in a month compared to the total number of person-hours people would like to work.
