Use the following production function and parameters in the Solow growth model

$Y=4K^{\frac{1}{4}}(AL{)}^{\frac{3}{4}}$; population growth rate is $2\mathrm{.}3\%$; saving rate is $27\%$; depreciation rate is $7\mathrm{.}6\%,$ and technological progress is $1\mathrm{.}1\%.$

$7.$ Actual investment exceeds breakeven investment at $k=625.$

$8.$ In the transition to the golden rule capital stock, the path of consumption falls for the current generation.

$9.$ The growth rate of $(\frac{Y}{L})$ in the steady state less than $3\mathrm{.}4\%.$

$10.$ For base year GDP to increase by three fold in $21$ years, the constant growth rate should be $5\mathrm{.}23\%.$
