Spain's central bank was lauded for macroprudential supervision before the housing bubble burst. Will China's central bank and financial authorites which have managed the housing bubble upto this point face similiar problems? Can China be the sole exception even as housing bubbles burst with wide repercussions in the U.S., UK and Spain? Nicholas Lardy, of the Peterson Institute of international Economics, says urban housing stock makes up 41% of Chinese household wealth in 2011. The same figure for the U.S. is 26%. Chinese buyers invest in homes because low interest rates on savings accounts cannot keep up with inflation. Real estate investment was 13% of GDP in 2011. Home ownership is a recent development in China, only since 1990, Chinese have never experienced large price declines. Household debt as a percentage of disposable income has increased significantly in recent years, up to 53.6% in 2011 from 31.3% in 2008, according to Lardy.

A number of issues came up at the Women20 Summit in Berlin. Annette Niederfranke, Director of the International Labor Organization, brought up the issue of family reconciliation as "one of the toughest challenges for working women worldwide," that in order to meet obligations women tended to work in "non standard forms of employment and in part time work linked to lower wages, lower social security, lower benefits, and fewer training possibilities." Childcare was also an issue that was prominent considering the lack of adequate childcare in many countries including in the European Union. With responsibilities for the elderly, babies, and small children women tend to be in the workforce for shorter periods leading to men taking up many of the higher positions. Angela Merkel pointed out that Gemany tended to take a narrow view of professions available to girls, saying- "So it is very very important that we take a broader view of things while girls are still at school." Merkel also supports a Africa compact that would help women set up small and middle size businesses in poor countries. The "Digital" aspects of this and other efforts for women were a major topic being discussed. One idea that came up was that more cooperation from men was needed to make things happen. This is the third Women20 Summit after ones in Turkey and China, and a sense of momentum was felt by women. ...

How ethanol picture as a useful alternative fuel has changed completely in the past year. The economics of ethanol also have changed completedly in the past year, as corn prices have risen to above $3 abushel and stayed there, even with the biggest corn crop since 1945, and prices of ethanol have dropped with huge oversupply of ethanol from $5 a gallon in June 2006 to about $1.85 a gallon today. Global ethanol production has grown from 10.9 billion gallons in 2006 to 13.4 billion gallons in 2007 according to IEA. US's ethanol production is about half of this or 7 billion gallons and is up 80% in 2 years. The production capacity of ethanol with new plants is expected to jump to about 12 billion gallons in 2008 even as demand for ethanol is about 7 billion gallons.This huge oversupply accounts for the drop in prices of ethanol with margins dropping from $2.30 in 2006 to 25 cents in late 2007. Its become less and less attractive as an alternative fuel as more studies appear and more groups cite the different ways in which ethanol has destructive effects on the environment. Corn is in demand by food companies and by livestock companies in the USA and generally across the developing world so raising corn prices is seen very unfavorably around the world. Nation Academy of Sciences study and a National Research Council study says corn based ethanol could strain water supplies and impair water quality. American Lung Assocation worries about the the air pollution from burning ethanol in gasoline. And a EPA Spring 2007 report says ozone levels increase with increased use of ethanol. A study coauthored by Nobel prize winning chemist Paul Crutzen says it might exacerbate climate change because of the added fertilizer used to produce corn raised emissions of nitrous oxide. All this has made people wary of ethanol and much of the early enthusiasm for ethanol has vanished. The lobbying struggle pits the ethanol producers and the farm lobby in the midwest against oil companies which don't like being forced to use a non-petroleum fuel even with a subsidy of 54 cents of gallon for blending ethanol into gasoline, and food and livestock companies which need corn at lower prices. Add to this the weight of environmental organizations and countries across the developing world which simply don't like the idea of using scarce food resources in this manner and find this to be just not a right thing to do for the world's poor which need corn as a basic food source. Consider Mexico where this affects the price of a staple food corn tortillas and China which bans the use of corn for making biofuels, both countries seek to keep food prices low for the country's large numbers of rural and urban poor people and could see the stability of these countries disturbed by huge rise in food or fuel prices. As a result of all this the ethanol lobby is looking to Congress to mandate a certain usage figure of ethanol in gasoline production in the new energy law. This legislation now could become controversial in the future as better ways of solving the energy crisis such as automobile fuel efficiency reducing demand and conservation, as well as other alternative sources that have fewer adverse environmental impact come into play. ...
