Beginning from a steady state in the Solow growth model, explain how an increase in the savings rate will affect the levels and growth rates of capital and output per worker?

Solutions

Expert Solution

Answer.

Solow model shows that saving rate is an important factor that determine steady state capital stock. When saving rate increase then economy will have large capital stock and high level of output at steady state.

The Solow model shows that increase in saving rate will increase the growth rates of capital and output per worker. But this increase will be only temporary because once an economy attains new steady state , growth will eventually stop. Therefore it is said that saving rate will have only level effect.

The following diagram depicts the effect of higher savings on growth where k* is the steady state level of capital per worker and k** is the steady state after increase in the saving rate. Y axis is depreciation and investment, whereas X axis is capital per worker.

Consider an economy at the steady state according to the Solow Growth Model with a per capita production function where n=0.04, d=0.08, and s=0.3. Suppose a change in the age profile of the population leads to a reduction of the savings rate to s=0.28. As a result, consumption initially falls and continues to decline until reaching the new steady state. consumption initially rises and continues to increase until reaching the new steady state. that is above the original. consumption initially rises...

Suppose we started out at the steady state capital stock in the basic Solow growth model. If there subsequently were a decrease in the demand for loanable funds due to less favorable tax treatment of business investment (and no shift in the supply of loanable funds), then we would expect to see: a. economic growth rates increase in the short run and the nation's capital stock to grow from its current level. b. economic growth rates become negative in the...
