This represents GDP because all the production in an economy (the left hand side of the equation) is used as consumption (C), investment (I), government spending (G), and goods that are exported in excess of imports (NX). Another equation defining GDP using alternative terms (which in theory results in the same value [citation needed]) is
This refers to the change in income for a population (for example, a change in GDP). [2] The arrows pointing out of "absolute poverty," "growth," and "inequality" in the Poverty-Growth-Inequality Triangle represent cause and effect. In the model, inequality and growth affect each other and both of them affect absolute poverty. [2]
An economic model is a theoretical construct representing economic processes by a set of variables and a set of logical and/or quantitative relationships between them. The economic model is a simplified, often mathematical, framework designed to illustrate complex processes. Frequently, economic models posit structural parameters. [1]
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.
For example, purchasing power parity comparisons of currencies are often constructed with indexes. There is a substantial body of economic analysis concerning the construction of index numbers, desirable properties of index numbers and the relationship between index numbers and economic theory.
Typical exercises of qualitative economics include comparative-static changes studied in microeconomics or macroeconomics and comparative equilibrium-growth states in a macroeconomic growth model. A simple example illustrating qualitative change is from macroeconomics. Let: GDP = nominal gross domestic product, a measure of national income M ...
A foreign direct investment (FDI) refers to purchase of an asset in another country, such that it gives direct control to the purchaser over the asset (e.g. purchase of land and building). In other words, it is an investment in the form of a controlling ownership in a business, in real estate or in productive assets such as factories in one ...
In finance, arbitrage pricing theory (APT) is a multi-factor model for asset pricing which relates various macro-economic (systematic) risk variables to the pricing of financial assets. Proposed by economist Stephen Ross in 1976, [ 1 ] it is widely believed to be an improved alternative to its predecessor, the capital asset pricing model (CAPM ...
