Land Regulation in Brazilian Cities

It is somewhat difficult to find academic studies about Brazilian cities published in English. So here are some interesting papers I would recommend on Land Regulations in Brazilian Cities.
  1. Avila (2006) Urban Land Use Regulations in Brazilian Cities - Impacts on Urban Land Markets and Access of Low Income People to Land and Housing. This chapter starts only at page 216, buthe book as a whole is highly recommended!

  2. LallWang; da Mata (2006) Do Urban Land Regulations Influence Slum Formation? Evidence from Brazilian Cities (I saw this paper on Richard K. Green's blog)

  3. Smith; Raemaekers (1998) Land use pattern and transport in Curitiba

  4. Dowall; Monkkonen (2007) Consequences of the Plano Piloto: The Urban Development and Land Markets of Brasília (you may access the working paper version here)

If you have any other suggestions, let us know with a comment !

Shrinking life expectancies in the USA

The average life expectancy of least-educated whites in the U.S. is shrinking. (via MR and GS)

[image credit: NYT]
"The reasons for the decline remain unclear, but researchers offered possible explanations, including a spike in prescription drug overdoses among young whites, higher rates of smoking among less educated white women, rising obesity, and a steady increase in the number of the least educated Americans who lack health insurance."
In case you want to read the published paper.

The home-ownership debate

The Economist Magazine has published a new 'Economist debate'. Should home-ownership be discouraged? (via Richard Green)

Green and Glaeser put the trade-off between market failure costs and public intervention costs in a very straightforward way. Very good food for thought! although I believe the market failures in the Brazilian housing sector (slums, informal markets, urban infrastructure deficit etc.) are quite different from those in the USA.

Anyway, perhaps the Brazilian Government should consider Glaeser's statements and rethink its housing policy.

The footprint of the world’s largest metros

A comparison of the built-up area of 129 'extended metros' that represent 35% of the world's urban population: Measuring the Human Urban Footprint (by LSE)

Take a look at the striking difference between Hong Kong and Atlanta. Pop density in Hong Kong is almost 24 times bigger than in Atlanta! Say it '24'.
