An endogenous growth theory implication is that policies that embrace openness, competition, change and innovation will promote growth. [ citation needed ] 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 ...
The Uzawa–Lucas model is an economic model that explains long-term economic growth as consequence of human capital accumulation. Developed by Robert Lucas, Jr., [1] building upon initial contributions by Hirofumi Uzawa, [2] it extends the AK model by a two-sector setup, in which physical and human capital are produced by different technologies.
Robert Lucas, Jr. adopted the concept to explain increasing returns to embodied human capital. [6] Xiaokai Yang and Jeff Borland have shown learning-by-doing plays a role in the evolution of countries to greater specialisation in production. [7] In both these cases, learning-by-doing and increasing returns provide an engine for long run growth.
Lucas and Paul Romer heralded the birth of endogenous growth theory and the resurgence of research on economic growth in the late 1980s and the 1990s. [ 23 ] [ 24 ] Lucas also contributed foundational contributions to behavioral economics, and provided the intellectual foundation for the understanding of deviations from the law of one price ...
Lucas summarized his critique: [4] Given that the structure of an econometric model consists of optimal decision rules of economic agents, and that optimal decision rules vary systematically with changes in the structure of series relevant to the decision maker, it follows that any change in policy will systematically alter the structure of ...
The AK model of economic growth is an endogenous growth model used in the theory of economic growth, a subfield of modern macroeconomics.In the 1980s it became progressively clearer that the standard neoclassical exogenous growth models were theoretically unsatisfactory as tools to explore long run growth, as these models predicted economies without technological change and thus they would ...
Arrow was one of the precursors of endogenous growth theory, which seeks to explain the source of technical change, which is a key driver of economic growth. Until this theory came to prominence, technical change was assumed to occur exogenously —that is, it was assumed to occur outside economic activities, and was outside (exogenous) to ...
An endogenous change is a change in an endogenous variable in response to an exogenous change that is imposed upon the model. [ 1 ] : p. 8 [ 3 ] : p. 8 The term ' endogeneity ' in econometrics has a related but distinct meaning.
