Distribution in
economics refers to the way total output or income is distributed among individuals or among the
factors of production (
labor,
land, and
capital) (Samuelson and Nordhaus, 2001, p. 762). In general theory and the
national income and product accounts, each unit of output corresponds to a unit of income. One use of national accounts is for classifying
factor incomes and measuring their respective shares, as in National Income. But, where focus is on income of persons or households, adjustments to the national accounts or other data sources are frequently used. Here, interest is often on the fraction of income going to the top (or bottom) x percent of households, the next y percent, and so forth (say in quintiles), and on the factors that might affect them (globalization, tax policy, technology, etc.).
