According to Kaldor, “The purpose of a theory of economic growth is to show the nature of non-economic variables which ultimately determine the rate at which the general level of production of the economy is growing, and thereby contribute to an understanding of the question of why some societies grow so much faster than others.” [2] [1]
Spear and Young re-examine the history of optimal growth during the 1950s and 1960s, [8] focusing in part on the veracity of the claimed simultaneous and independent development of Cass' "Optimum growth in an aggregative model of capital accumulation" (published in 1965 in the Review of Economic Studies), and Tjalling Koopman's "On the concept ...
A Robinson Crusoe economy is a simple framework used to study some fundamental issues in economics. [1] It assumes an economy with one consumer, one producer and two goods. The title "Robinson Crusoe" is a reference to the 1719 novel of the same name authored by Daniel Defo
The Harrod–Domar model dominated growth theory until Robert Solow [c] and Trevor Swan [d] independently developed neoclassical growth models in 1956. [55] Solow and Swan produced a more empirically appealing model with "balanced growth" based on the substitution of labor and capital in production. [59]
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]
Economic growth may be defined as a production increase of an output of a production process. It is usually expressed as a growth percentage depicting growth of the real production output. The real output is the real value of products produced in a production process and when we subtract the real input from the real output we get the real income.
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 supply is a good or service that producers are willing to provide. The law of supply determines the quantity of supply at a given price. [5]The law of supply and demand states that, for a given product, if the quantity demanded exceeds the quantity supplied, then the price increases, which decreases the demand (law of demand) and increases the supply (law of supply)—and vice versa—until ...
