National income in the context of "Wage share"

Although for many decades, it was customary to focus on GDP and other measures of national income, there has been growing interest in developing broad measures of economic well-being. National and international approaches include the Beyond GDP programme developed by the European Union, the Better Lives Compendium of Indicators developed by the OECD, as well as many alternative metrics of wellbeing or happiness. One of the earliest attempts to develop such an index at national level was Bhutan's Gross National Happiness Index and there are a now a number of similar projects ongoing around the world, including a project to develop for the UK an assessment of national well-being, commissioned by the Prime Minister David Cameron and led by the Office for National Statistics.

Macroeconomics is a branch of economics that deals with the performance, structure, behavior, and decision-making of an economy as a whole. This includes regional, national, and global economies. Macroeconomists study topics such as output/GDP (gross domestic product) and national income, unemployment (including unemployment rates), price indices and inflation, consumption, saving, investment, energy, international trade, and international finance.

Macroeconomics and microeconomics are the two most general fields in economics. The focus of macroeconomics is often on a country (or larger entities like the whole world) and how its markets interact to produce large-scale phenomena that economists refer to as aggregate variables. In microeconomics, the focus of analysis is often a single market, such as whether changes in supply or demand are to blame for price increases in the oil and automotive sectors. From introductory classes in "principles of economics" through doctoral studies, the macro/micro divide is institutionalized in the field of economics. Most economists identify as either macro- or micro-economists.

In national income accounting, net national income (NNI) is net national product (NNP) minus indirect taxes. Net national income encompasses the income of households, businesses, and the government. Net national income is defined as gross domestic product plus net receipts of wages, salaries and property income from abroad, minus the depreciation of fixed capital assets (dwellings, buildings, machinery, transport equipment and physical infrastructure) through wear and tear and obsolescence.

The three-sector model in economics divides economies into three sectors of activity: extraction of raw materials (primary), manufacturing (secondary), and service industries which exist to facilitate the transport, distribution and sale of goods produced in the secondary sector (tertiary). The model was developed by Allan Fisher, Colin Clark, and Jean Fourastié in the first half of the 20th century, and is a representation of an industrial economy. It has been criticised as inappropriate as a representation of the economy in the 21st century.

According to the three-sector model, the main focus of an economy's activity shifts from the primary through the secondary and finally to the tertiary sector. Countries with a low per capita income are in an early state of development; the main part of their national income is achieved through production in the primary sector. Countries in a more advanced state of development, with a medium national income, generate their income mostly in the secondary sector. In highly developed countries with a high income, the tertiary sector dominates the total output of the economy.

Financialization (or financialisation in British English) is a term sometimes used to describe the development of financial capitalism during the period from 1980 to the present, in which debt-to-equity ratios increased and financial services accounted for an increasing share of national income relative to other sectors.

Financialization describes an economic process by which exchange is facilitated through the intermediation of financial instruments. Financialization may permit real goods, services, and risks to be readily exchangeable for currency and thus make it easier for people to rationalize their assets and income flows.
