'''Factor income''' is the income that the owners of the factors of production receive in return for supplying them to the production process. Labour earns wages and salaries, capital earns profits, interest, and rents, and land and natural resources earn rents. Factor income is the primary income generated in production, before taxes and transfers, and its distribution among labour and capital is a central question in economics and in the analysis of inequality.

== Components ==

Compensation of employees is the largest component of factor income in most economies. It includes wages and salaries, bonuses, and social contributions paid by employers. Operating surplus is the income accruing to capital and to unincorporated businesses, and it includes profits, rents, and the surplus of the self-employed. The sum of compensation of employees and operating surplus, together with taxes less subsidies on production, makes up the income generated in production, or gross value added at factor cost.

Factor income can be measured gross or net of depreciation. Gross figures include the consumption of fixed capital, while net figures deduct it and therefore represent the income available for distribution or reinvestment. The distinction matters because high gross operating surplus may reflect a large capital stock that must be maintained rather than income that can be consumed.

== Distribution between labour and capital ==

The split of factor income between labour and capital, often called the labour share, has attracted much attention. The share of compensation of employees in national income was long regarded as roughly constant, a regularity noted by early economists and incorporated into models of growth and distribution. In recent decades, however, the labour share has declined in many economies, prompting research into its causes and consequences.

Explanations for the decline include globalisation and the integration of large labour-abundant economies, technological change that substitutes capital for labour, the rise of market power and of intangible assets, and changes in the bargaining power of workers and in the coverage of collective bargaining. The decline has implications for inequality, since capital income is more concentrated than labour income, and for aggregate demand, since capital owners tend to save a larger share of their income.

== National versus domestic concepts ==

A distinction is drawn between domestic factor income and national factor income. Domestic factor income is generated within the borders of a country, while national factor income adjusts for net factor income from abroad, that is, the income of residents from abroad minus the income of non-residents generated domestically. Gross national income equals gross domestic product plus net factor income from abroad, and it is the more appropriate measure of the income available to residents.

For countries with large stocks of foreign assets or liabilities, the difference between domestic and national concepts can be substantial. A country that hosts large foreign-owned firms may have high domestic product but lower national income, because profits accrue to foreign owners. Conversely, a country with large foreign investments may have national income above domestic product. These distinctions matter for assessing living standards and external positions.

== Accounting and analysis ==

Factor income is recorded in the national accounts, which decompose it into its components and reconcile it with the production and expenditure measures of output. The accounts also show the flows of taxes, subsidies, and transfers that transform factor income into disposable income. Analysing these flows illuminates how the income generated in production is distributed, redistributed, and used.

Economists study factor income to understand growth, distribution, and the functioning of labour and capital markets. Changes in the composition of factor income over time reflect structural change, shifts in technology, and changes in institutions. The measurement of factor income, including the treatment of the self-employed and of intangible capital, remains an active area of statistical work, since accurate measurement is essential to credible analysis.

== Factor income in open economies ==

In open economies, factor income crosses borders. Residents earn wages, profits, interest, and rents from abroad, and non-residents earn income from domestic production. Net factor income from abroad, the difference between the two, is added to gross domestic product to obtain gross national income. For countries with large foreign investments or with many citizens working abroad, this adjustment can be substantial and can materially change assessments of living standards.

Remittances, the transfers sent home by migrant workers, are related but distinct: they are current transfers rather than factor income, but they are often the most important external flow for many developing economies. Together with net factor income, they determine the resources available to residents, and their measurement and stability are matters of concern for policymakers, because they affect consumption, the balance of payments, and the vulnerability of the economy to external shocks.

== Technological change and the labour share ==

Technological change affects the division of factor income. Automation and the use of capital-intensive methods can raise the share of income accruing to capital, particularly where technology substitutes directly for labour. The growth of intangible assets, including software, data, and intellectual property, has increased the returns to capital and has complicated the measurement of factor shares, because investment in intangibles is treated differently across statistical systems.

At the same time, technology can raise the productivity of labour and increase the demand for skilled workers, raising their wages and their share of income. The net effect on the labour share depends on the balance between substitution and productivity effects and on the distribution of gains across workers. Understanding these dynamics is essential for assessing the effects of technological change on inequality and for designing policies, such as education and training, that spread the benefits of innovation.

== Factor income and macroeconomic stabilisation ==

The composition of factor income influences macroeconomic behaviour. Because the recipients of capital income tend to save a larger share of their income than wage earners, a shift of income toward capital can reduce aggregate consumption for a given level of output, weakening demand. This effect is relevant to debates about the causes of persistently weak demand and about the role of distribution in determining the level of economic activity.

The distribution of factor income also affects the response to shocks. If income is concentrated, consumption may be more volatile, since it depends on the spending of a few large recipients. Adjustment to shocks, including the response to changes in the terms of trade or in technology, depends on how the resulting gains and losses are distributed across factors and on how the affected groups respond. The analysis of factor income is therefore integral to understanding both distribution and macroeconomic dynamics.
