Residential Location and Retirement Age

The new issue of Urban Studies is out and this paper caught my attention. It might interest some of you as well!

Abstract: Retirement age choice is introduced into a conventional model of residential location to show that the retirement age of workers who do not move after retirement can be influenced by the urban variation of leisure and housing prices. A retirement demand equation that incorporates commuting characteristics is estimated on a sample of US urban male owners interviewed by the Panel Study of Income Dynamics. It is found that commuters retire around two years earlier than comparable home-based workers, although the evidence provides no support for this gap to be the result of differences in leisure or housing prices across both groups.

Buenos Aires Urban Expansion

A gif depicting Buenos Aires urban expansion in three different time periods: until 1947; from 1947 to 1972 and 1972 onwards (thanks Leonardo Garateguy for the tip).

It's important to stress the avant-garde urbanization of Buenos Aires in contrast to other Latin American cities. Much could be said about this, but it would be out of our purpose with this blog. Besides, Guillhermo Tella probably has much more interesting things to say about it.
