lec 3 endegonous growth models Flashcards
what is the romer model
technological progress driven by
search for new ideas by researchers who profit from their
inventions —- a new idea
allows a given bundle of inputs to produce more or better
output
what does romer try say
technological process is the main driver of economic growth
why do we r and d
so induviduals can profit from the researchbenefitting society
more people meansin endogenous models
more people, more researchers, more inventors more technological evolution
what will achieve higher levels of researchincentive-
intellectual property rights and rewards for being sound - subsidys, grants all that jazz
why do romer and solow differ
romer follows an endegenous model for understanding long term growth, understanding investment in human capital is key for long run growth — solow focuses on shorter term on how accumulation of capital and growth in the labor force, treating savings, tech as exogenous to its model.
what does romer say about long run growth
indifferent to change in the investment rate. the amount of money invested or how many people are doing research rather built on people and their innovations
what is the main understanding of solow in the long run
capital and workers have diminishing returns and the rate of growth is dependent on the increases in TFP or productivity and technological improvements
what do exogenous models understand?
understand that savings and technological evolution is exogenous and taken as given. Focus on the idea that investment rates facilitate level of growthand that an efficient level of physical capital to population will lead to growth
what do endegenous models understand
long run grwth is dependent on ideas, knowledge, research etc
what did barro do
measure growth using initial income, capital, fertilkity, stability, price levels and govt interventions
did barro find income convergence
y
does human capital matter? barro
y alot for growth
what are barro findings?
Income convergence does exist, if underlying predictors of
growth were accounted for
* Growth is positively related to human capital
* Growth is negatively related to government intervention into
economy, political instability
* This empirical research opened room for further theories of
growth and development
kremer understood what
following romer, understands inventions are a public bonus and that those with larger populations should grow faster - relevant b4 1500 where knowledge exchange was less viable
