This article develops an overlapping generations model to show how demography and savings affect the relationship between real exchange rate (RER) and productivity. In high-saving (low-saving) countries and/or low-population-growth-rate countries, a rise in productivity leads to a real...

We consider a one-sector growth model which combines overlapping generations of finite lived agents and infinite lived consumers. We show that two types of equilibrium may exist. A first type corresponds to the modified golden rule if the stationary consumption of infinite lived agents is...
