So the basic theory says that raising the minimum wage helps workers whose wages are raised, and hurts people who are not hired (or lose their jobs) because companies cut back on employment. But proponents of the minimum wage hold that the situation is much more complicated than the basic theory can account for.
One complicating factor is possible
monopsony in the labor market, whereby the individual employer has some market power in determining wages paid. Thus it is at least theoretically possible that the minimum wage may boost employment. Though single employer market power is unlikely to exist in most labor markets in the sense of the traditional '
company town,' asymmetric information, imperfect mobility, and the 'personal' element of the labor transaction give some degree of wage-setting power to most firms.
[21]
[edit] Criticism of the "textbook model"
The argument that minimum wages decrease employment is based on a simple supply and demand model of the labor market. A number of economists (for example Pierangelo Garegnani,
[22] Robert L. Vienneau,
[23] and Arrigo Opocher & Ian Steedman
[24]), building on the work of
Piero Sraffa, argue that that model, even given all its assumptions, is logically incoherent. Michael Anyadike-Danes and Wyne Godley
[25] argue, based on simulation results, that little of the empirical work done with the textbook model constitutes a potentially falsifying test, and, consequently, empirical evidence hardly exists for that model. Graham White
[26] argues, partially on the basis of Sraffianism, that the policy of increased labor market flexibility, including the reduction of minimum wages, does not have an "intellectually coherent" argument in economic theory.
Gary Fields, Professor of Labor Economics and Economics at
Cornell University, argues that the standard "textbook model" for the minimum wage is "ambiguous", and that the standard theoretical arguments incorrectly measure only a one-sector market. Fields says a two-sector market, where "the self-employed, service workers, and farm workers are typically excluded from minimum-wage coverage… [and with] one sector with minimum-wage coverage and the other without it [and possible mobility between the two]," is the basis for better analysis. Through this model, Fields shows the typical theoretical argument to be ambiguous and says "the predictions derived from the textbook model definitely do not carry over to the two-sector case. Therefore, since a non-covered sector exists nearly everywhere, the predictions of the textbook model simply cannot be relied on."
[27]
An alternate view of the labor market has low-wage labor markets characterized as
monopsonistic competition wherein buyers (employers) have significantly more
market power than do sellers (workers). This monopsony could be a result of intentional collusion between employers, or naturalistic factors such as segmented markets, search costs, information costs, imperfect mobility and the 'personal' element of labor markets. In such a case the diagram above would not yield the quantity of labor clearing and the wage rate. This is because while the upward sloping aggregate labor supply would remain unchanged, instead of using the downward labor demand curve shown in the diagram above, monopsonistic employers would use a steeper downward sloping curve corresponding to marginal expenditures to yield the intersection with the supply curve resulting in a wage rate lower than would be the case under competition. Also, the amount of labor sold would also be lower than the competitive optimal allocation.
Such a case is a type of
market failure and results in workers being paid less than their marginal value. Under the monopsonistic assumption, an appropriately set minimum wage could increase both
wages and
employment, with the optimal level being equal to the
marginal productivity of labor.
[28] This view emphasizes the role of minimum wages as a
market regulation policy akin to
antitrust policies, as opposed to an illusory "
free lunch" for low-wage workers.
Another reason minimum wage may not affect employment in certain industries is that the demand for the product the employees produce is highly inelastic;
[29] For example, if management is forced to increase wages, management can pass on the increase in wage to consumers in the form of higher prices. Since demand for the product is highly inelastic, consumers continue to buy the product at the higher price and so the manager is not forced to lay off workers.
Three other possible reasons minimum wages do not affect employment were suggested by
Alan Blinder: higher wages may reduce
turnover, and hence training costs; raising the minimum wage may "render moot" the potential problem of recruiting workers at a higher wage than current workers; and minimum wage workers might represent such a small proportion of a business's cost that the increase is too small to matter. He admits that he does not know if these are correct, but argues that "the list demonstrates that one can accept the new empirical findings and still be a card-carrying economist."
[30]
[edit] Debate over consequences
Various groups have great ideological, political, financial, and emotional investments in issues surrounding minimum wage laws. For example, agencies that administer the laws have a vested interest in showing that "their" laws do not create unemployment, as do labor unions, whose members' jobs are protected by minimum wage laws. On the other side of the issue, low-wage employers such as restaurants finance the Employment Policies Institute, which has released numerous studies opposing the minimum wage.
[31] The presence of these powerful groups and factors means that the debate on the issue is not always based on dispassionate analysis. Additionally, it is extraordinarily difficult to separate the effects of minimum wage from all the other variables that affect employment.

The following table summarizes the arguments made by those for and against minimum wage laws:
Arguments in favor of Minimum Wage Laws Supporters of the minimum wage claim it has these effects:
- Increases the standard of living for the poorest and most vulnerable class in society and raises average.[1]
- Motivates and encourages employees to work harder[32]
- Stimulates consumption, by putting more money in the hands of low-income people who spend their entire paychecks.[1]
- Increases the work ethic of those who earn very little, as employers demand more return from the higher cost of hiring these employees.[1]
- Decreases the cost of government social welfare programs by increasing incomes for the lowest-paid.[1]
- Encourages people to join the workforce rather than pursuing money through illegal means, e.g., selling illegal drugs [33][34]
- Encourages efficiency and automation of industry.[35]
- Removes low paying jobs, forcing workers to train for, and move to, higher paying jobs.[36][37]
- Increases technological development. Costly technology that increases business efficiency is more appealing as the price of labour increases.[38]
Arguments against Minimum Wage Laws Opponents of the minimum wage claim it has these effects:
- As a labor market analogue of political-economic protectionism, it excludes low cost competitors from labor markets and hampers firms in reducing wage costs during trade downturns. This generates various industrial-economic inefficiencies.[39]
- Hurts small business more than large business. [40]
- Reduces quantity demanded of workers, either through a reduction in the number of hours worked by individuals, or through a reduction in the number of jobs.[41][42]
- May cause price inflation as businesses try to compensate by raising the prices of the goods being sold.[43][44]
- Benefits some workers at the expense of the poorest and least productive.[45]
- Can result in the exclusion of certain groups from the labor force.[46]
- Small firms with limited payroll budgets cannot offer their most valuable employees fair and attractive wages above unskilled workers paid the artificially high minimum, and see a rising hurdle-cost of adding workers.[47]
- Is less effective than other methods (e.g. the Earned Income Tax Credit) at reducing poverty, and is more damaging to businesses than those other methods.[48]
- Discourages further education among the poor by enticing people to enter the job market.[48]
In 2006, the
International Labour Organization (ILO)
[8] argued that the minimum wage could not be directly linked to unemployment in countries that have suffered job losses. In April 2010, the
Organisation for Economic Co-operation and Development (OECD)
[49] released a report arguing that countries could alleviate teen unemployment by “lowering the cost of employing low-skilled youth” through a sub-minimum training wage. A study of U.S. states showed that businesses' annual and average payrolls grow faster and employment grew at a faster rate in states with a minimum wage.
[50] The study showed a correlation, but did not claim to prove causation.
Although strongly opposed by both the business community and the
Conservative Party when introduced in 1999, the minimum wage introduced in the UK is no longer controversial and the Conservatives reversed their opposition in 2000.
[51] A review of its effects found no discernible impact on employment levels.
[52] However, prices in the minimum wage sector were found to have risen significantly faster than prices in non-minimum wage sectors, most notably in the four years following the implementation of the minimum wage.
[53]
Since the introduction of a national minimum wage in the
UK in 1999, its effects on employment were subject to extensive research and observation by the Low Pay Commission. The Low Pay Commission found that, rather than make employees redundant, employers have reduced their rate of hiring, reduced staff hours, increased prices, and have found ways to cause current workers to be more productive (especially service companies).
[54] Neither trade unions nor employer organizations contest the minimum wage, although the latter had especially done so heavily until 1999.
