2 · Analysis · Medium · Technological Progress and Balanced Growth
In the Solow growth model with technological progress (where technology grows at rate g_{A} and labor grows at rate g_{N}), which of the following will decrease the steady-state growth rate of output per worker?
Tap an answer. The explanation will appear here, including why each wrong option is wrong.
Not quite. D is correct.
In the steady state (balanced growth path), output per worker grows strictly at the rate of technological progress g_{A}. A reduction in the rate of technological progress reduces this steady-state growth rate.

3 · Analysis · Hard · Solow Model with Technological Progress
Using the Solow growth model with technological progress, explain the effects of an increase in the saving rate. Describe how the relevant curves shift on a diagram measuring capital per effective worker (K/AN) on the horizontal axis and output/investment per effective worker on the vertical axis. Detail what happens to the steady-state levels of capital and output per effective worker, as well as the transition paths and long-run steady-state growth rates of total output and output per worker.

Model answer. 1. Graphical representation: On a graph with capital per effective worker (K/(AN)) on the horizontal axis and output/investment per effective worker on the vertical axis, the required investment line is given by (delta + g_{A} + g_{N})K/(AN) and the investment function is s*f(K/(AN)). An increase in the saving rate s shifts the investment curve upward while the required investment line remains unchanged.\n2. Steady-state levels: At the initial steady state, investment now exceeds required investment, inducing capital deepening. Over time, the economy moves to a new steady state with permanently higher levels of capital per effective worker (K*/(AN)) and output per effective worker (Y*/(AN)).\n3. Growth rates: During the transition, the growth rate of output per worker increases beyond g_{A}, and the growth rate of total output increases beyond g_{A} + g_{N}. Once the new steady-state equilibrium is reached, both growth rates slow down and return to their original values: output per worker grows at g_{A}, and total output grows at g_{A} + g_{N}. Thus, saving rate changes exert level effects, not permanent growth effects.
