The GDP per capita in Japan increased more than 5.3% annually 1960 and 1990, while the growth rate of GDP per capita in the US was only 2.2%. This growth difference could be due to which of the following?

False
The existence of the steady state in the Solow model is guaranteed by the assumption that production function is constant returns to scale
False
The golden rule refers to the optimal investment strategy that maximizes capital intensity in the long run.
False
If country Fast grows faster than country Slow, then country Fast must be poorer than country Slow at this moment
False Reasoning:
In a world of Solow, a reduction of population growth rate can raise a country's growth rate in the long run but its living standard in the short run
False Reasoning: Increases growth rate in the short run and living standard in the long run

Even though capital per worker in India was less than 1/20 of that in the U.S. at the end of World War II, India's growth rate stayed low. This could be due to which of the following fact(s)

Which of the following is a correct analysis on how international trade affects growth?
Access to the international market provides the opportunity for a country with lagging technology to catch up; hence the import that is accompanied by flow of knowledge (machineries and equipment) is positively correlated with growth
Both UK and Venezuela invested about 18% of their FDP per year during the period 1960-1990. The capital per worker in the UK more than doubled, while that in Venezuela increased less than 50%. This could be due to the fact (a) the population growth rate in Venezuela is much higher; (b) the total factor productivity (TFP) in the U.K is higher.

Data shows that political instability is negatively correlated with economic growth. This is because
The risk of investing in physical capital, human capital, and better technology are all increased
Country A and B have the same population, investment rate and depreciation rate. In country A population growth rate is 1%, while in country B it is 3%. If both countries started with the same amount of capital, subsequently

A major earthquake destroyed a significant portion of buildings and structures in country H. A just in time warning of the earthquake, on the other hand, left most of the residents unharmed. According to the Solow growth model, we should observe a higher growth rate in the near future.
True
An increase of efficiency in the education sector can increase the growth rate of living standard both in the long run and in the short run
True
Anti-trust regulation promote economic growth as competition is more conducive to innovation and adoption of new technology.
True
Both country A and B reside in a Solow world. Country A is more efficient at producing things than country B. Everything else is the same. Residents in country A produce more and enjoy more goods and services than those in country B in the long run.
True
Country X lives in the world of Solow. It is at its steady state. An economist calculated its marginal product of capital and found that it is more than the rate of depreciation plus the population growth rate. Country X can increase its consumption per capita in the long run if it raises its investment rate.
True

True

True
In the short run, increasing on-the-job training of a country's labor force can increase its growth rate
True
Two countries reside in the world of Solow. The only difference between them is the population growth rate. The country with a higher population growth rate will grow slower in the short run and be poorer in the long run
True
In the world of Solow, if everything else is the same, a country with a higher investment rate has a higher capital intensity for sure but may not have a higher consumption per capita at the steady rate.
True Reasoning: According to the Solow model of long-run economic growth, higher rates of saving lead to higher capital intensity per person but not necessarily higher consumption per per person. An increase in saving rate/investment rate leads to a higher K/L and hence higher level of per capita output, with this there may be an increase in per capita consumption but an increase in saving rate also lowers the consumption share of income.
Out of the following, which is the LEAST likely example of an increase in total factor productivity
an increase in immigration
Everything else is the same, a country that is more efficient at producing goods and services is expected to
be richer in the long run and grow faster in the short run

co-movement
The Golden Rule of capital accumulation maximizes the steady-state level of
consumption per capita
GDP per capita has been
converging among some countries, bit not some others
If the correlation between GDP and y is -0.75, we say y is
countercyclical
At the steady state of the Solow model a fall of total factor productivity (TFP)
decreases both capital and output per capita
At the steady state of the Solow model, an increase in population growth rate
decreases both capital and output per capita
In the Solow growth model output per capita eventually stops growing because
diminishing marginal product of capital
At the steady state of a Solow model, an increase of productivity
increases capital, output and consumption per capita
If the correlation between GDP and y is 0.55, we say y is
procyclical
Real consumption tends to be
procyclical and less variable than real GDP
We say than an economy is in a recession if
real GDP growth rate is slower than a trend
