Spear and Warren Young Introduction: scope and method In previous papers (Spear and Young 2014, 2015a, 2015b), we surveyed the origins, evolution and dissemination of optimal growth, two sector and turnpike, and stochastic growth models. E000079 endogenous growth Endogenous growth theory explains long-run growth as emanating from economic activities that create new technological knowledge. The pioneer of "endogenous growth theory" is Paul Romer, a former colleague but not a relative of our textbook author.1 His 1986 paper in the Journal of Political Economy is a seminal work in the modern revitalization of growth theory. These new ideas make everyone else producing regular goods and services more productive - that is, ideas increase TFP. Capital is accumulated in the usual, Solow-type manner: where s is the savings rate, and is the rate of depreciation.

E000079 endogenous growth Endogenous growth theory explains long-run growth as emanating from economic activities that create new technological knowledge. The neoclassical growth theory has had as its reference point the growth model of Solow (1956). 2. Stokey and Rebelo (1995) and Lucas (1990) argue that if endogenous growth models are calibrated to plausible values the effect on welfare is not likely to be large. The theory is built on the idea that improvements in innovation, knowledge, and human capital lead to increased productivity, positively affecting the economic outlook. Solow (1970:2) agrees with the stylised label, but casts doubt on the factual claim. Another branch of growth theory comes under the heading of Endogenous Growth.

The Solow- Swan neoclassical growth model . Neoclassical version of the AK model: Very tractable and applications in many areas. Once the cost has been incurred, the instructions can be used over and over at no additional cost. Exogenous vs. Endogenous Growth Models • Exogenous model - Y 1= AKa L -a - Productivity levels (A) are given/residual - Diminishing returns inhibit sustained growth (limited to a steady-state) • Endogenous models - Productivity accounted for within the model; an explanation for A • R&D, Human Capital - Constant marginal productivity Taking Stock 526 11.6. The neoclassical growth theory has had as its reference point the growth model of Solow (1956). 2. Daron Acemoglu (MIT) Economic Growth Lectures 9 and 10 Nov. 29 and Dec. 4 18 / 73 He nevertheless concedes that "they are what most of the theory of economic growth actually explains".

Neoclassical version of the AK model: Very tractable and applications in many areas. This article sketches the outlines of the theory, especially the 'Schumpeterian' variety, and briefly describes how the theory has evolved in response to empirical discoveries. 2. Endogenous Growth Model and New Explanatory Variable The mainline Endogenous Economic Growth Model Identifies Human Capital as the key to sustainable Technological Advance in the long run. It is a new theory which explains the long-run growth rate of an economy on the basis of endogenous factors as against exogenous factors of the neoclassical growth theory. Endogenous Growth Theory and the Relevance of Romer's Contribution. In this paper we explored the equilibrium dynamics of an innovative economy, via an endogenous growth model with physical capital, human capital, and R&D. In the second section we developed a model of endogenous growth with innovation and derive the differential equations that describe the dynamics of the economy. It is a new theory which explains the long-run growth rate of an economy on the basis of endogenous factors as against exogenous factors of the neoclassical growth theory. 2. Exogenous growth is only one type model that researchers have developed.

First-Generation Models of Endogenous Growth 505 11.1. Two-sector endogenous growth models behave very similarly to the baseline AK model, but avoid this. The problem of decreasing marginal returns Decreasing marginal returns are necessary for well-behaved supply curves But for long-run economic growth they pose a problem For an ever expanding economy, growth will stop as a result of decreasing marginal . The Two-Sector AK Model 516 11.4. The AK Model This model is an alternative model of endogenous growth. Growth Theories - Growth Theories Lecture 1 of Eco 317 J.D. But given its historical place as the -rst endogenous growth model, the AK paradigm is an important part of any economist™s toolkit. There are many variants of endogenous growth theory, but a . Such an equilibrium can alternatively be referred to as a fisteady statefl, since it is a steady state in transformed variables. 3. The AK Model Revisited 506 11.2. Instructions for working with raw materials different from other economic goods. Endogenous Technological Change Paul M. Romer University of Chicago Growth in this model is driven by technological change that arises from intentional investment decisions made by profit-maximizing agents. Endogenous Growth Theory: The endogenous growth theory is an economic theory which argues that economic growth is generated from within a system as a direct result of internal processes. The problem of decreasing marginal returns Decreasing marginal returns are necessary for well-behaved supply curves But for long-run economic growth they pose a problem For an ever expanding economy, growth will stop as a result of decreasing marginal . We assume that A is some positive constant. Technical change arises because of intentional actions taken by profit maximizing agents who respond to market incentives. !
