Neoclassical growth theory, or also known as the Solow growth theory or exogenous growth theory, posits that long term, sustained economic growth is only possible through technological progress and innovation which increases the efficiency of labor. Changes inside saving and/or investment rate only induces short word growth, wherever diminishing returns to capital force the economy to return to a steady region level. However, it does not explains how or why technological progress is determined or created; it is assumed that this technological progress is exogenous; that is, determined by factors outside the consideration on the model.
Critics on the Solow growth design say that that is an unrealistic assumption that doesn't reflect the underlying economic reality. Their answer towards the Solow growth model of exogenous technological growth is a type of endogenous growth, in which technological progress is mentioned and determined by factors during the scope with the model. A lot more specifically, according to Roberts and Setterfield, endogenous growth theory, in their very own words, have Two major variants, namely:
An endogenous growth theory is one exactly where the rate of growth is determined by the equilibrium item of the growth type itself, instead of getting imposed upon the design from without (exogenously); or
An endogenous growth theory is a single wherever technical progress is explicitly modeled, rather than being treated as exogenously given “manna from heaven”
Attempts to explain the rate of technological progress has made a type of endogenous growth, wherever constant returns to capital are the underlying assumption, compared to diminishing returns to capital in the Solow model. This can be made possible by the broad assumption that human knowledge and skills are also a form of capital, and as soon as accumulated; they do not exhibit the properties of diminishing returns simply because more of it does not “crowd out” other principal causes of capital, relative to other traditional varieties of capital. Three In addition, new knowledge begets additional knowledge, which *might* have a virtuous cycle effect at best, and reduce knowledge depreciation at worst. Knowledge can be viewed as a public excellent which advantages society being a whole. This makes it a a lot more plausible description of lengthy term economic growth.
One with the key benefits on the endogenous growth type is that federal government policy decisions can permanently raise a country’s growth rate if they lead to much more technological progress and innovation, hence doing growth endogenous, as its name suggests. This also emphasize the role of private investment in search and development as the central source of technical progress and innovation, due to the fact most search and development is driven by a profit motive to be able to capture a short term monopoly or patent, under which more profits can also be made. This suggests that the protection of house rights and patents can improve the incentives for individual organizations to engage in look for and development. Other policies such as reducing the federal deficit to lower interest rates so that investment in capital and technological look for is going to be simulated, as well as doing it easier for men and women to obtain themselves through a lot more education and training by diminishing the cost of student loans and increasing jobs pay are also techniques which could increase growth under endogenous growth theory.

Hence this can be the principal attraction of endogenous growth theory – that governments could quickly discover possible and reasonably traditional policies that could influence the lengthy term growth rate positively, which would be a huge achievement in between the several typical goals of economic policy. However, endogenous growth theory just isn't without having it’s problems. A single on the main failing of endogenous growth theory (theories) is their collective failure to explain non-convergence in between rich and poor countries more than the extended term. In other words, it's unable to explain in adequate detail why some nations are even now much richer than others.
Endogenous growth theory can be characterized by some limitations, numerous of which has its roots in its reliance on formal models which fail to capture the value with the socio-institutional context4. There must not be an obsession of the formal derivation of new general growth equations. However, endogenous growth models can also be employed to raise queries and possibilities which in turn support empirical inquiry and analysis, which would be more intriguing and have more potential.
