National income accounting represent the process of working out measures of a country’s income and production such as gross domestic product (GDP), gross national income (GNI), net national product (NNP), disposable personal income, etc.
Gross national income (GNI) is a measure of income earned by a country’s nationals/residents anywhere in the world. It equals gross domestic product (GDP) plus net factor income from abroad.
Circular flow diagram shows how income flows in an economy between households, firms and government in product markets, factors of production markets and financial markets.
Core inflation is a measure of changes in prices of goods and services that offer a long-run view of purchasing power by excluding volatile commodities such as food and energy items.
Nominal GDP tells about the current market value of final goods and services produced in an economy. Real GDP, on the other hand, is a measure of total production at constant prices. Change in real GDP over the period is a measure of growth.
GDP deflator (also called implicit price deflator for GDP) is a measure of price level of domestically-produced goods and services in an economy. It is calculated by dividing nominal GDP by real GDP multiplied by 100.
Inventory investment, also referred to as change in private inventories (CIPI) by the BEA, is a component of gross private investment of GDP that represents the difference between production and sales during the period.
Gross domestic product (GDP) is a measure of national income which equals the market value of all final goods and services produced in the geographical boundaries of a country in a given time period.
Total factor productivity (TFP) is a measure of productivity calculated by dividing economy-wide total production by the weighted average of inputs i.e. labor and capital. It represents growth in real output which is in excess of the growth in inputs such as labor and capital.
Cobb-Douglas production function is a model that tells us about the relationship between total product, total factor productivity, quantities of labor and capital and their output elasticities.
