Urban Demographics is now on Twitter !


Spread the words: we are now on Twitter ! @UrbDemographics

I'm still learning how to use it. You will have to be patient with me during this test period.

Baby Deficit and Economic Crises

In his paper 'The Baby Deficit' Science 2006Michael Balter points out why public policies are unlikely to reverse fertility declines. His abstract couldn't be more brief:

"As fertility rates decline across the developed world, governments are offering big incentives for childbearing. Experts don't expect them to have much effect."

And talking about fertility reversion, economic recession will not help much in that. Read this NYT piece Fewer Births in a Bad Economy. How low can fertility get in Europe?

Untangling the City

A new CASA Working Paper by Michael Batty. I will probably take a few hours to really understand the paper. But I'll try it !

[image credit: ?    I love this image. It reminds me of a movie scene from 'Inception']

According to M. Batty, the paper describes "the transition from thinking of ‘cities as machines’ to ‘cities as organisms’". I wonder what could be clinically diagnosed as an urban cancer...

NeW! 'Prata da Casa' session: regional and urban economics handbook

I'm starting a new post session called "Prata da Casa" to recommend some good research and publications by my colleagues here at the Institute for Applied Economic Research (IPEA).

"Prata da Casa" is a Portuguese expression that in this case refers to some good 'homegrown research'. So I'm inaugurating this session with a recent regional and urban economics handbook with emphasis on Brazil:

Regional and Urban Economics: Theories and methods with emphasis on Brazil (organized by Bruno Cruz, Bernardo Furtado, Leonardo Monasterio and Waldery Rodrigues Júnior) - Portuguese Version Only

off-topic: Modernist Modernist Monuments

I bumped into these bizarre and still beautiful Modernist Monuments. I would say that we have something similar here in Brasília in a much smaller scale with the Crystals Square (by Burle Marx).

This reminded me of a book with fascinating photos from Frederic Chaubin depicting socialist architectural eccentricities:

Key Works in Sociology

I have told you that one of my favorite books in sociology is "Suicide: a study in Sociology" by Émile Durkheim (1858-1917). 

My second favorite author is Erving Goffman with his microsociology approach in "The Presentation of Self in Everyday Life".

The demographic challenge in Brazil

OECD has just published its 'Economic Surveys' on Brazil (thanks Leo for the tip). According to the report, the aging of the population is a major challenge in Brazil. This is not big news, but they say it in a concise manner:

"Like many emerging-market economies, Brazil’s population is going to age rapidly in the coming decade (Figure 1). The share of the elderly population is expected to double in less than 20 years, a transition that took around three times as long for today’s advanced economies. These demographic changes will alter the  macroeconomic environment. Assuming no policy changes, lower working-age population growth could lower potential output growth significantly by the middle of the century. This fall will most probably be partially compensated by the effect of the Growth Acceleration Programme (PAC) on productivity growth, but that impact is hard to estimate. Ageing is also likely to increase savings through life-cycle dynamics, although in Brazil’s case prospects for aggregate savings will depend on the effectiveness of social and labour-market policies in continuing to lower the share of poor households, who traditionally save less. Ageing will also tilt public spending toward greater outlays on old-age pensions and health and long-term care and less on education, but the aggregate impact on public finance is likely to be negative."

Figure 1.  The speed of population ageing*
*Number of years for the share of population 65+ to double from around 10% to around 20%
Note: United Nations population projections have been used. Numbers for France and the United Kingdom correspond to an increase from 12% to around 20%.
