Solow Growth Model: Predicting Real GDP Per Capita Growth

The Solow growth model predicts that the growth rate of real GDP per capita will eventually converge to a steady-state level in the long run. This steady-state level is determined by factors such as population growth, technological progress, and capital accumulation.

According to the Solow growth model, in the initial stages of development, countries with lower levels of capital per worker will experience higher growth rates of real GDP per capita. This is because the diminishing returns to capital imply that additional investment leads to higher productivity gains in countries with lower initial levels of capital.

However, as a country continues to accumulate capital, the growth rate of real GDP per capita will gradually slow down. Eventually, it will reach a steady-state level where the growth rate is determined by exogenous factors such as technological progress and population growth. At this steady state, the growth rate of real GDP per capita will be equal to the growth rate of technological progress minus the population growth rate.

In summary, the Solow growth model predicts that the growth rate of real GDP per capita will initially be higher for countries with lower initial levels of capital. However, over time, the growth rate will converge to a steady-state level determined by technological progress and population growth.
