A variety of measures of national income and output are used in economics to estimate total economic activity in a country or region, including gross domestic product (GDP), Gross national income (GNI), net national income (NNI), and adjusted national income (NNI adjusted for natural resource depletion – also called as NNI at factor cost).
Gross national product (GNP) is the market value of all the goods and services produced in one year by labor and property supplied by the citizens of a country. Unlike gross domestic product (GDP), which defines production based on the geographical location of production, GNP indicates allocated production based on location of ownership.
Seven summary accounts are published, as well as a much larger number of more specific accounts. The first summary account shows the gross domestic product (GDP) and its major components. The table summarizes national income on the left (debit, revenue) side and national product on the right (credit, expense) side of a two-column accounting report.
A macroeconomic model is an analytical tool designed to describe the operation of the problems of economy of a country or a region. These models are usually designed to examine the comparative statics and dynamics of aggregate quantities such as the total amount of goods and services produced, total income earned, the level of employment of productive resources, and the level of prices.
A common way to observe such behavior is by looking at a time series of an economy's output, more specifically gross national product (GNP). This is just the value of the goods and services produced by a country's businesses and workers. Figure 1 shows the time series of real GNP for the United States from 1954 to 2005.
GDP (Gross Domestic Product) is the value of all goods and services sold within a country during one year. GDP measures flows rather than stocks (example: the public deficit is a flow, the government debt is a stock). Flows are derived from the National Accounting relationship between aggregate spending and income. Ergo:
The Galor-Zeira model, established by Oded Galor and Joseph Zeira in 1988, is the first macroeconomic model to examine the influence of economic inequality on macroeconomic dynamics. The model disputes the previously prevalent view, held by the representative agent approach in macroeconomics till the early 1990s, that economic inequality has no ...
In economics, an input–output model is a quantitative economic model that represents the interdependencies between different sectors of a national economy or different regional economies. [1] Wassily Leontief (1906–1999) is credited with developing this type of analysis and earned the Nobel Prize in Economics for his development of this model.
