Daron Acemoglu (MIT) Economic Growth Lectures 9 and 10 Nov. 29 and Dec. 4 18 / 73 The endogenous growth theory is the concept that economic growth is due to factors that are internal to the economy and not because of external ones. 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. But given its historical place as the -rst endogenous growth model, the AK paradigm is an important part of any economist™s toolkit. 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 The theory is built on the idea that improvements in innovation, knowledge, and human capital lead to increased productivity, positively affecting the economic outlook. Swan, Cass Koopmans. Once the cost has been incurred, the instructions can be used over and over at no additional cost. Neoclassical version of the AK model: Very tractable and applications in many areas. Solow, T.W. 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. 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. endogenous growth model (65% of consumption) than it is in a neoclassical growth model (1.6% of consumption) ! Endogenous Growth Theory and Models: the "First Wave", 1952-1973 Stephen E. 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. The endogenous growth theory is the concept that economic growth is due to factors that are internal to the economy and not because of external ones. Another branch of growth theory comes under the heading of Endogenous Growth. The distinguishing feature of the technology as an input is that it is neither a conventional good nor a public good; it is a non- . Such an equilibrium can alternatively be referred to as a fisteady statefl, since it is a steady state in transformed variables. E000079 endogenous growth Endogenous growth theory explains long-run growth as emanating from economic activities that create new technological knowledge.

Chapter 11. 2. In Chapter 3, we presented the Solow Growth model, an example of exogenous growth model on account that the driver of economic growth, technological change, is determined outside the model. Solow (1970:2) agrees with the stylised label, but casts doubt on the factual claim. the endogenous growth theory. new theory of economic growth is an endogenous growth model is one in which the long run growth rate of an economy on the basis of endogenous factors, not an exogenous factors as in a neo classical growth model like those following from Ramsey, R.M.

Once the cost has been incurred, the instructions can be used over and over at no additional cost. The endogenous growth models - Overview The Jones critique Semi-endogenous growth models. 2. The neoclassical growth theory has had as its reference point the growth model of Solow (1956). 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 neoclassical growth theory has had as its reference point the growth model of Solow (1956). The Solow- Swan neoclassical growth model . We assume that A is some positive constant.

Note that this "gift" of the AK model is also its "curse." 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 . 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. In endogenous growth models we define capital as physical and human capital- so . 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.

These new ideas make everyone else producing regular goods and services more productive - that is, ideas increase TFP. Theory of economics In endogenous growth models we define capital as physical and human capital- so . 2. 3. His endogenous growth theory ties the development of new ideas to the number of people working in the knowledge sector (think of this as effort devoted to R&D). 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.

Conclusions. Endogenous growth: growth in per capita output depends on the economic decisions . The endogenous growth theory was developed as a reaction to omissions and deficiencies in the Solow- Swan neoclassical growth model. growth modeling, what is endogenous in endogenous growth models is the theory of technical progress incorporated into the models.This one was an important achievement, because it opened the door to a new research line with realistic features. Swan, Cass Koopmans. He nevertheless concedes that "they are what most of the theory of economic growth actually explains". Accordingly we devote this chapter to developing the AK model and to summarizing the empirical debate that took place in the 1990s between growth. 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. 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.

Endogenous Growth Theory and the Relevance of Romer's Contribution. Technical change arises because of intentional actions taken by profit maximizing agents who respond to market incentives. 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. Technical change arises because of intentional actions taken by profit maximizing agents who respond to market incentives. Exogenous growth is only one type model that researchers have developed. Two-sector endogenous growth models behave very similarly to the baseline AK model, but avoid this. 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. We de-ne a balanced growth path (BGP) as an equilibrium path where C (t),X (t),Z (t) and N (t) grow at a constant rate.

Capital is accumulated in the usual, Solow-type manner: where s is the savings rate, and is the rate of depreciation.
