Functional Distribution of Income:
Functional distribution of income refers to the returns to labour, land and capital as determined by factor prices, utilization levels, and the consequent share of the .national income that accrue to the owners of each factor. The theory of functional distribution is also known as the theory of factor prices as it deals with factor prices like rent, wages, interest and profits. In the Eighteenth century, Ricardo analysed the income distribution among social classes based on the analysis of the functional distribution as the capitalists and landlords owned the means of production and received profit and rent respectively for using their resources and labour received wages as they had only their labour power to sell. Later, Marx considered only profit and wages as two major components of functional distribution of income which would indicate the pattern of income distribution in society. Both Ricardo and Marx argued that the process of economic growth will lead to inequality as the share of landowners (Ricardo's argument) and profits of capitalists (Marx's argument) will go up with progress.
The functional distribution of incomealso considers the decomposition of incomes based on profits and interest, transfer payments, pension rights. The finer decomposition of income distribution provides a correct picture of income distribution, therefore, it is important to study the distribution of other assets like stocks, land, houses and other forms in which wealth is stocked. A long term study of the functional distribution or the decomposition of income would give an accurate assessment of the size distribution of income levels in a country. Size distribution of income is an indicator of the spread of income levels amongst households. A more equal distribution of income occurs when greater share of the incremental income goes to the lower income classes.
The implications of functional distribution of income on poverty refer to factor price distortions that enter in economic decision-making as a result of various factors. As economies progress and the levels of economic activities go up, there will be changes in the value of stocks and assets such as land or houses. This would lead to changes in incomes of various households with access to such assets. It could also deal with policy interventions for altering the functional distribution of the share of factors
engaged in the development process.
