Abstract

In the AK model of growth, a country’s output per capita grows linearly with investment as a percentage of GDP. The model predicts that changes in policies that affect the investment rate should in turn affect growth rates, given a fixed capital-output ratio and depreciation, allowing an endogenous form of growth. The theory thus requires fundamental similarity in the dynamics of economic growth and investment rates for an economy.
