Measuring pure health inequality and mobility during a health insurance expansion: Evidence from Mexico.

The association of insurance expansions and the distribution of health status is still a matter we know little about. This paper draws upon new measures of pure (univariate) inequality and mobility which accommodate categorical data to understand how an expansion of public insurance may be related to both health inequality and mobility. These measures require a definition of individual's status that is either "downward looking" or "upward looking".

Piketty in the long run.

I examine the idea of 'the long run' in Piketty (2014) and related works. In contrast to simplistic interpretations of long-run models of income- and wealth-distribution Piketty (2014) draws on a rich economic analysis that models the intra- and inter-generational processes that underly the development of the wealth distribution. These processes inevitably involve both market and non-market mechanisms.
