The fundamental contradiction of capitalism revisited

Abstract

We build an overlapping generations model to analyse the evolution of inequality as an economy develops. Our model economy resembles a very capitalist society'. Initially, wealth is exclusively concentrated in a rich dynasty. We ask whether or not this type of capitalist economy contains a fundamental contradiction, as claimed by Piketty in his recent book. We derive a condition under which the economy is driven to a state of perpetual inequality. However, we also show that an economy where capital deepening triggers the development process is very unlikely to be absorbed in that state.
