Borderless Economics

Another book added to my cart on Amazon: Borderless Economics (written by Robert Guest, The Economist’s Business Editor).

Among other things, the book tackles brain drain and global poverty, how migration fosters innovation and cultural syncretism and how it is infecting China with ideas that will eventually turn it democratic.

You may find the author talking about the book here (a 15 minute Interview).

By the way, there is another book on migration that might interest you (available for free download.): The State of Environmental Migration (SEM) 2010. It's a co-publishing by IDDRI and the International Organisation for Migration (IOM), edited by François Gemenne, Pauline Brücker and Joshua Glasser. I thank Ojima for the tip!

The Economist house-price indicators and the Chinese housing bubble

The Economist Magazine updated its house-price indicators.They say that the bursting of the global housing bubble is only halfway through

Krugman and Wendell Cox have a few words suggesting why we shouldn't be so optimistic about the Chinese real estate market.

Exceptional Space - book recommendation

I would like to reccomend a book for those Space Syntax enthusiasts: Exceptional Space by Prof. Frederico Holanda (this is the English edition of his doctoral thesis, supervised by Professor Bill Hillier). I have read the portuguese version and it is a terrifc book for urban planners, geographers or sociologists with focus on the spatial dimension of human relations.

Fertility Transition in Brazil

Mapping the Timing, Pace, and Scale of the Fertility Transition in Brazil - a recent paper by Potter, Cavenaghi and others published at PDR.

It's a very interesting paper even if you are not into fertility studies. And you can have some fun with their data and maps !

Housing Finance Policy and Segregation

This would be a very nice hypothesis to be tested for the Brazilian case. Brazil had a huge housing finance policy from the 60's to the 80's with the National Housing Bank (BNH). Since 2009 the Federal Government has been carrying out a very big social housing program called Minha Casa, Minha Vida (My House, My Life). I think this is a good idea to consider if you are a PhD candidate in Brazil.

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:

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*

Countdown to a World of 7 Billion

UNFPA has just published this year's State of World Population report. Yes! According to official estimateswe, we are about to reach 7 Billion People on earth. So I decided to replay this post:

And talking about the world population, every now and then someone comes up with the overpopulation issue. Usually it is referred to as the "overpopulation problem" or the "demographic bomb".

This is the promo motion graphic for the World Population Special Series brought by National Geographic (the article here and some pictures here). I couldn't agree more with these two conclusive excerpts:

"But one can also draw a different conclusion—that fixating on population numbers is not the best way to confront the future. People packed into slums need help, but the problem that needs solving is poverty and lack of infrastructure, not overpopulation. Giving every woman access to family planning services is a good idea—“the one strategy that can make the biggest difference to women’s lives,” Chandra calls it. But the most aggressive population control program imaginable will not save Bangladesh from sea level rise, Rwanda from another genocide, or all of us from our enormous environmental problems."

"The number of people does matter, of course. But how people consume resources matters a lot more. Some of us leave much bigger footprints than others. The central challenge for the future of people and the planet is how to raise more of us out of poverty—the slum dwellers in Delhi, the subsistence farmers in Rwanda—while reducing the impact each of us has on the planet."
