The Solow model problem in macroeconomics and why the Solow model technique is the source of long te

The increase in population growth means an increase in the labor force, and the total output and total capital continue to increase, but it pulls down GDP per capita and output per capita. In the steady state of the law, the marginal output of capital minus depreciation is equal to the rate of population growth.

Solow's economic growth model is a well-known model in development economics proposed by Robert Solow, also known as the neoclassical economic growth model and exogenous economic growth model, which is an economic growth model within the framework of neoclassical economics. Just in 1987, when the world market was **, the Royal Swedish Academy of Sciences announced that the Nobel Prize in economics for that year was awarded to Robert Solow, a professor at the Massachusetts Institute of Technology in the United States who had been contrary to Reagan's economic policy and advocated that he must effectively intervene in the market economy. However, his theory ——— a long-term economic growth model that shows how different factors affect economic growth and development, and he proposed it as early as 30 years ago in a paper entitled "Contributions to the Theory of Economic Growth".

Solow model. c.Technological progress) is a source of long-term economic growth.

Analysis: Solow's economic growth model argues that technological progress is the source of long-term economic growth in a country. However, technological progress is an exogenous variable and a flaw in the Solow model.

FYI.

As long as it's a growth accounting formula.

y growth rate. The growth rate of technology + the growth rate of k + the growth rate of l (the sum of the ratio of capital and income is 1).

The share of capital in income is 30% - so labor is 70% of the share of income, capital is 30% of income, and the growth rate of labor is.

Total capital grows at 3% per year--- so the growth rate of k is the rest is that the growth rate of technology is 3%.

This is a neoclassical growth problem that takes into account technological progress.

Output equation: y=f(an, k), where an is the efficient labor that takes into account technological progress.

The basic equation of the neoclassical growth model: k*=sy*-(n+g+δ)k*The meaning of the symbols in the above equation: k* is the average rate of capital growth by effective labor, s is the savings rate, y* is the per capita output per capita by effective labor, n is the population growth rate, g is the rate of technological progress, δ is the depreciation rate, and k* is the per capita capital per capita according to the average effective labor.

When the economy reaches equilibrium, k*=0, then the equation for equilibrium is sy*=(n+g+δ)k*, and then y=root k, y*=y a, k*=k a. Bringing it into the equilibrium equation, multiplying s by the root number k=(n+g+δ)k, and bringing in the known data, k=16 (when s=28%), the equilibrium output is y=4.

When s=10%, n=4%, y=1.

This is the second question.

Looking for Yin Bocheng's green book, "Macroeconomics" is a similar topic above, I have read it, hehe, I am too lazy to type, sorry.

You're a big worker, hehe, just look at Mr. Ding's courseware, there's no need to kneel and beg here.

This is Mankiw's macroeconomics exercise, the answer is not this, but I feel that the answer is wrong
