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.
Endogenous growth theory holds that investment in human capital, innovation, and knowledge are significant contributors to economic growth. The theory also focuses on positive externalities and spillover effects of a knowledge-based economy which will lead to economic development.
Lucas (1988) is a seminal contribution in the economic development and growth literature. [22] 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]

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.
The Lucas critique suggests that if we want to predict the effect of a policy experiment, we should model the "deep parameters" (relating to preferences, technology, and resource constraints) that are assumed to govern individual behavior: so-called "microfoundations."
In macroeconomics, the cost of business cycles is the decrease in social welfare, if any, caused by business cycle fluctuations.. Nobel economist Robert Lucas proposed measuring the cost of business cycles as the percentage increase in consumption that would be necessary to make a representative consumer indifferent between a smooth, non-fluctuating, consumption trend and one that is subject ...
