A fundamental question in social sciences relates to the effect of wealth inequality on economic growth. Yet, in tackling the question, researchers have had to use income as a proxy for wealth. We derive a global measure of wealth inequality from Forbes magazine's listing of billionaires and...

How to explain rising income and wealth inequality? We build an original heterogeneous-agent model with three key features: (i) an explicit link between firm's market power and top income shares, (ii) a granular representation of the tax and transfer system, and (iii) three assets with...

This article reviews the distribution of income and wealth in the US from three basic perspectives that tend to be otherwise overlooked if the subject is framed primarily on the basis of the gross statistics: a) quantity and quality of work effort; b) quantity and quality of capital...

This paper argues that an increase in the inequality of wealth prompts a stronger quest for status that in turn fosters the accumulation of wealth. It proposes a measure for an individual’s want of social status. For a given level of a population’s wealth, the corresponding aggregate measure...

This paper analyzes the relationship between mean income and the income of the rich. Our methodology closely follows that of Dollar and Kraay (2002), but instead of looking at the bottom of the distribution, we analyze the top. We use panel data from the World Top Incomes database, which...

We consider a highly stylized, yet non trivial model of the economy, with a public and private sector coupled through a wealth tax and a redistribution policy. The model can be fully solved analytically, and allows one to address the question of optimal taxation and of wealth inequalities. We...

For Piketty there are two laws of capitalism and one fundamental inequality which, taken together, drive us towards a world of increasing inequality. For what is left of the twenty-first century he foresees a less meritocratic society with an enhanced role for inherited wealth. In this article I...
