$4...$ Multiple Answer:$$The fertility rate in India declined from $5\mathrm{.}9$ in $1960$ to $2\mathrm{.}2$ in $2020,$ contributing to slower population growth. According to$$SGM$1,$ what will be the impact of slower population growth on the$$steady$-$state level$$of capital per worker and output per worker?

$$ The steady$-$state level of capital per worker will increase

$$ It depends on the saving rate

$$ The steady$-$state level of capital per worker will decrease

$$ The steady$-$state level of capital per worker and output per worker is determined by$$g

$$ It depends on the growth rate of technological innovation

$$ The steady$-$state level of output per worker will decrease

$$ It depends on the depreciation rate

$$ The steady$-$state level of output per worker will increase

$$

$7....$ Multiple Answer:$$The household saving rate in Sweden increased from about $4\mathrm{.}9$ percent in $1995$ to $17$ percent in $2020.$ According to$$SGM$1,$ in Sweden$$s new steady state

$$ the marginal product of capital will remain unchanged

$$ consumption per worker will be lower

$$ investment per worker will be higher

$$ consumption per worker will be higher

$$ the level of capital per worker will be lower

$$ the level of output per worker will be lower

$$ the level of capital per worker will be higher

$$ the depreciation rate will decrease

$$ consumption per worker may be higher or lower, depending on whether the new steady state is closer to or further from the golden rule level of capital per worker

$$ level of capital per worker and output per worker is determined by$$g

$$ the level of output per worker will be higher

$$ the marginal product of capital will be higher

$$ the population growth rate will increase

$$ investment per worker will be lower

$$ the marginal product of capital will be lower

$$

$8...$ Question $81$pts

Multiple Answer & follow$-$up$-$ to $7$:$$According to$$SGM$1,$ what will happen to the$$growth rate$$of capital per worker and output per worker during the transition from the old to the new steady state?

$$ It depends on the saving rate

$$ The growth rate of output per worker will be negative

$$ It depends on the depreciation rate

$$ The growth rate of capital per worker will decrease at a decreasing rate

$$ The growth rate of capital per worker and output per worker is zero

$$ The growth rate of output per worker will decrease at a decreasing rate

$$ The growth rate of capital per worker will be positive

$$ It depends on the growth rate of technological innovation

$$ The growth rate of output per worker will be positive

$$ The growth rate of capital per worker will be negative

$$

$9...$Use the Solow Growth Model $2($SGM$2),$ which includes depreciation, population growth, and technological innovation to answer questions $9-13.$

Multiple Answer:$$According to$$the Solow Growth Model $($SGM$2),$ differences in standards of living across countries, measured by the level of income per person, can be due to

$$ differences in the overall size of the population

$$ differences in the population growth rate

$$ differences in the growth rate of workers$$ productivity or effectiveness

$$ differences in the rate of depreciation of capital

$$ different initial levels of capital per worker relative to a common steady state

$$ differences in the saving rate

$$
