Abstract

What is the relationship between the economy's long‐run growth rate, its capital‐income ratio, and its factor income distribution? A satisfactory answer requires an endogenous growth and savings rate. We scrutinize Piketty's (2014) theory in a richly parameterized variant of Romer's (1990) seminal model with and without population growth. The economy's growth and savings rate are exogenous in Piketty's theory and endogenous in Romer's. In contrast to Piketty's Second Fundamental Law of Capitalism a smaller growth rate may be associated with a smaller capital‐income ratio. Moreover, it may go together with a greater or a smaller capital share. (JEL E10,E21,E25,O33,O41)
