GDP PPP Per Capita IMF 2008. The endogenous growth theory primarily holds that the long run growth rate of endogenous growth model pdf economy depends on policy measures.
It uses the assumption that the production function does not exhibit diminishing returns to scale to lead to endogenous growth. However, the endogenous growth theory is further supported with models in which agents optimally determined the consumption and saving, optimizing the resources allocation to research and development leading to technological progress. D to the growth model. The AK model works on the property of absence of diminishing returns to capital. 1 explains the perpetual growth, with exogenous technical progress.
The per capita growth depends on behavioural factors of the model as the saving rate and population. However, the savings rate and rate of technological progress remain unexplained. Households are assumed to maximize utility subject to budget constraints while firms maximize profits. Often endogenous growth theory assumes constant marginal product of capital at the aggregate level, or at least that the limit of the marginal product of capital does not tend towards zero. This does not imply that larger firms will be more productive than small ones, because at the firm level the marginal product of capital is still diminishing.
Generally monopoly power in these models comes from the holding of patents. D sector develops ideas that they are granted a monopoly power. An endogenous growth theory implication is that policies that embrace openness, competition, change and innovation will promote growth. Conversely, policies that have the effect of restricting or slowing change by protecting or favouring particular existing industries or firms are likely, over time, to slow growth to the disadvantage of the community. Sustained economic growth is everywhere and always a process of continual transformation. The sort of economic progress that has been enjoyed by the richest nations since the Industrial Revolution would not have been possible if people had not undergone wrenching changes.
Economies that cease to transform themselves are destined to fall off the path of economic growth. Another frequent critique concerns the cornerstone assumption of diminishing returns to capital.

These kind of neoclassical prepositions have the resemblance with the philosophical contents in Ricardo and Malthus. The basic underlying assumption of neoclassical philosophical is that diminishing returns to capital operates in the production process. Thus the dissatisfaction out of neoclassical model motivated to construct new growth theories where the key determination of growth theories are endogenous in the model as in these new theories, the long run growth is not determined by exogenous factors setting up endogenous growth theories. The simplest version of endogenous model is AK models which assume constant exogenous saving rate and fixed level of technology.
The stickiest assumption of this model is that production function does not include diminishing returns to capital. This means that with this strong assumption the model can lead to endogenous growth. In the above equation A is the level of technology which is positive constant and K represents volume of capital.

This research investigates about the relation between demographic dynamics and economic growth, illustrating both orthodox and heterodox theories.
