Tariff Part of Wages, the bulk of the payment to workers in socialist state enterprises. For workers, it is payment for their labour according to the wage rate (see Tariff System under Socialism), for engineers, technicians and office employees— in accordance with their salary rates. Wages rates and salaries differ depending on the complexity, difficulty and importance of the work, as well as on workers’ skills. The tariff is, therefore, payment for the work rate, reflecting most fully the differences between various kinds of work. The other part of wages includes various forms of incentive payment for high achievement compared with the fixed rates. To these belong bonuses for overfulfilling output quotas, for fulfilling more than one trade, for upgrading one’s skills, for working in regions with poor economic and climatic conditions. These forms of wages boost the labour productivity, improve the quality of output, mobilise workers in fulfilling particularly important national tasks and help to attract and settle workers in regions with harsh climatic conditions. A number of measures have been taken of late to improve rates and regulate wage rating in order to make moral and material incentives more effective. This has increased the role of tariffs in the state regulation of wages. The role of wages in encouraging workers to improve their skills and attain higher work indices has increased. The income of each worker now depends closely on his or her personal share in social production. The role of bonuses, especially those from the material incentives fund (see Economic Incentives Funds), increases as scientific and technical progress gains impetus. Bonuses promote workers’ initiative and are an effective mechanism for encouraging them to seek inner reserves for raising the efficiency of social production and improving the quality of work.
