Transitional Dynamics of the Savings Rate in the Neoclassical Growth Model



This paper characterizes the transitional dynamics of the savings rate in the neoclassical growth model. I start with a general formulation with weak assumptions on preferences and technology and go on to fully describe the transitional behavior of the savings rate under particular functional forms. It is shown that under plausible functional forms for preferences and technology, the model is able to explain the hump-shaped behavior of the savings rate observed in most OECD countries in the period 1950-1990. The paper also provides econometric evidence supporting the empirical relevance of the neoclassical growth model in explaining the dynamics of the savings rate both in OECD countries and in a larger cross-section of countries.
