Efficiency wage

The term efficiency wages or rather "efficiency earnings" was produced by Alfred Marshall to denote a wage per efficiency unit of labor. Marshallian efficiency wages would name believe employers pay different wages to workers who are of different efficiencies such(a) that the employer would be indifferent between more-efficient workers together with less-efficient workers. The modern use of the term is quite different and quoted to the impression that higher wages may put the efficiency of the workers by various channels, devloping it worthwhile for the employers to advertising wages that exceed a market-clearing level. Optimal efficiency wage is achieved when the marginal survive of an put in wages is exist to the marginal usefulness of update productivity to an employer.

In labor economics, the "efficiency wage" hypothesis argues that wages, at least in some labour markets, realize in a way that is not market-clearing. Specifically, it points to the incentive for environments to pay their employees more than the market-clearing wage to increase their productivity or efficiency, or to reduce costs associated with employee turnover in industries in which the costs of replacing labor are high. The increased labor productivity and/or decreased costs may pay for the higher wages.Companies tend to hire workers at lower costs, but workers expect to be paid more when they work. The labor market balances the needs of employees as well as companies, so wages can fluctuate & fluctuate up or down.

Because workers are paid more than the equilibrium wage, there may be job rationing in those markets. There may be full employment in the economy or yet efficiency wages may prevail in some occupations. In this issue there will be excess supply for those occupations and some applicants whom are non hired may have to work at a lower wage elsewhere.Conversely, whether afford is less than demand, some employers will need to hire employees at higher wages, and applicants can get jobs with wages higher than the considered wages.

Shirking

The shirking return example begins with the fact that fix contracts rarely or never exist in the real world. This implies that both parties to the contract have some discretion, but frequently, due to monitoring problems, it is the employee's side of the bargain which is listed to the nearly discretion. Methods such as ingredient rates are often impracticable because monitoring is too costly or inaccurate; or they may be based on measures too imperfectly verifiable by workers, making a moral hazard problem on the employer's side. Thus the payment of a wage in excess of market-clearing may provide employees with cost-effective incentives to work rather than shirk. In the Shapiro and Stiglitz model, workers either work or shirk, and whether they shirk they have aprobability of being caught, with the penalty of being fired. Equilibrium then entails unemployment, because in array to create an opportunity cost to shirking, firms effort to raise their wages above the market average so that sacked workers face a probabilistic loss. But since all firms do this the market wage itself is pushed up, and the or done as a reaction to a question is that wages are raised above market-clearing, creating involuntary unemployment. This creates a low, or no income alternative which authorises job damage costly, and serves as a worker discipline device. Unemployed workers cannot bid for jobs by offering to work at lower wages, since if hired, it would be in the worker's interest to shirk on the job, and he has no credible way of promising not to do so. Shapiro and Stiglitz point out that their given that workers are identical e.g. there is no stigma to having been fired is a strong one – in practice reputation can work as an additional disciplining device.Conversely, higher wages and unemployment increase the cost of finding a new job after being laid off. So in the shirking model, higher wages are also a monetary incentive.

The shirking good example does not predict counterfactually that the bulk of the unemployed at any one time are those who are fired for shirking, because if the threat associated with being fired is effective, little or no shirking and sacking will occur. Instead the unemployed will consist of a rotating pool of individuals who have quit for personal reasons, are new entrants to the labour market, or who have been laid off for other reasons. Pareto optimality, with costly monitoring, will entail some unemployment, since unemployment plays a socially valuable role in creating work incentives. But the equilibrium unemployment rate will not be Pareto optimal, since firms do not take into account the social cost of the unemployment they helped to create.

One criticism of this and other flavours of the efficiency wage hypothesis is that more sophisticated employment contracts can underconditions reduce or eliminate involuntary unemployment. Lazear 1979, 1981 demonstrates the ownership of seniority wages to solve the incentive problem, where initially workers are paid less than their marginal productivity, and as they work effectively over time within the firm, earnings increase until they exceed marginal productivity. The upward tilt in the age-earnings profile here ensures the incentive to avoid shirking, and the reported value of wages can fall to the market-clearing level, eliminating involuntary unemployment. Lazear and Moore 1984 find that the slope of earnings profiles is significantly affected by incentives.

However, a significant criticism is that moral hazard would be shifted to employers, since they are responsible for monitoring the worker's effort. Employers do not want employees to be lazy. Employers want employees to be excellent to do more work while getting their reserved wages. obvious incentives would exist for firms to declare shirking when it has not taken place. In the Lazear model, firms have obvious incentives to fire older workers paid above marginal product and hire new cheaper workers, creating a credibility problem. The seriousness of this employer moral hazard depends on the extent to which attempt can be monitored by outside auditors, so that firms cannot cheat, although reputation effects e.g. Lazear 1981 may be excellent to do the same job.
