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]
The growth accounting model is normally expressed in the form of the exponential growth function. As an abstract example consider an economy whose total output (GDP) grows at 3% per year. Over the same period its capital stock grows at 6% per year and its labor force by 1%.
Important contributions to the model came from the work done by Solow and by Swan in 1956, who independently developed relatively simple growth models. [2] [3] Solow's model fitted available data on US economic growth with some success. [6] In 1987 Solow was awarded the Nobel Prize in Economics for his work. Today, economists use Solow's ...

The Dual Sector model, or the Lewis model, is a model in developmental economics that explains the growth of a developing economy in terms of a labour transition between two sectors, the subsistence or traditional agricultural sector and the capitalist or modern industrial sector.
Endogenous growth theory holds that investment in human capital, innovation, and knowledge are significant contributors to economic growth. The theory also focuses on positive externalities and spillover effects of a knowledge-based economy which will lead to economic development.
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.
Kaldor's growth laws are a series of three laws relating to the causation of economic growth. Looking at the countries of the world now and through time Nicholas Kaldor noted a high correlation between living standards and the share of resources devoted to industrial activity, at least up to some level of income. Only New Zealand, Australia and ...
