For statistical purposes, the relationship of employer to employee exists, when there is an agreement, formal or informal, between an enterprise and a person, normally entered into voluntarily by both parties, whereby the person works for the enterprise, in return for remuneration in cash or in kind. The remuneration is normally based on either the time spent at work, or some other objective indicator of the amount of work done.
For social accounting purposes, CE is considered a component of the value of net output or value added (as factor income). The aim is not to measure income actually received by workers, but the value which labour contributes to net output along with other factors of production. The underlying idea is that the value of net output equals the factor incomes that it generates. For this reason, some types of remuneration received by employees are either included or excluded, because they are regarded as either related or unrelated to production or to the value of new output.
In different countries, what is actually included and excluded in CE may differ somewhat. The reason is that the way in which workers are compensated for their labour may be somewhat different in different types of economies. For example, in some countries workers get substantial payments "in kind", in others they don't. Systems of social insurance also differ between countries, and some countries have little social insurance. One has to keep this in mind when comparing CE magnitudes for different countries.
A compensation system has to be aligned to the mission, vision, business strategy and organizational structure of a company to design the compensation plan in an efficient way to can achieve the goals. Businesses within the same organization will have different competitive conditions, acquire different business strategies, and design compensation strategies. A general compensation plan consists of three components: a base compensation, rewarding incentives, and indirect compensation in form of benefits.
