Should China Dump Dollars for Commodities? What about the "Nuclear Option" of Dumping Treasuries? Can Global Trade Collapse?

Every time there is a little blip by China in its purchasing or holding of US treasuries, hyperinflationists come out of the woodwork ranting about the "Nuclear Option" of China dumping treasuries en masse. Such fears are extremely overblown for several reasons...[Michael Pettis argues] the real problem is exactly the opposite of what most are ranting about: ``The problem facing the US and the world is not that China may stop purchasing US Treasury obligations. The problem is exactly the opposite. The major capital exporting countries -- China, Germany, and Japan -- are desperate to maintain or even increase their net capital exports, which are simply the flip side of their trade surpluses.'' ...If consumers decide to stop buying goods from China there is almost nothing China can do about it...Chinese exporters are already under severe price pressures...pray tell what is stopping a collapse in global trade? Nothing as far as I can see. It all depends on consumer attitudes. Certainly Bernanke and Congress will do their best efforts to get banks to lend and consumers to spend, it is by no means a certainty the Fed will succeed...consumer attitudes towards spending and debt will determine the global trade imbalance math...The result may be a collapse in global trade, not an inflationary event to say the least.

AlterNet: Hey, America: It's Time to Redefine the "Good Life"; excerpted from the The Spirit Level: Why Greater Equality Makes Societies Stronger

...We are social epidemiologists; people who usually spend their time trying to understand how social factors affect population health. Our work has focused on different aspects of wellbeing in rich market democracies. Rather than looking at subjective measures, such as happiness, we have looked at objective measures, such as life expectancy, homicide rates, drug abuse, child well-being, levels of trust, involvement in community life, mental illness, teenage birth rates, children's math and literacy scores, and the proportion of the population in prison. Instead of finding that each society does well on some of these outcomes and badly on others, we found that countries tend to be consistently good or bad performers, across the board. If a country has high life expectancy, it also tends to have stronger community life, a smaller proportion of its population behind bars, better mental health, fewer drug problems and children doing better in school. The differences in the performance of more and less equal countries are very large. Rather than things being just a bit worse in more unequal countries, they are very much worse. More unequal countries have three times the rates of violence, of infant mortality and of mental illness. Their teenage birth rates are six times as high, and rates of imprisonment are eight times higher...

Pricing a CDO - Not only Bad Math, Bad Computation too

A working paper, Computational complexity and informational asymmetry in financial products, Sanjeev Arora, Boaz Barak, Markus Brunnermeier, Rong Ge. sheds some light on the complex mathematical models upon which credit default obligations and other derivatives are based. What Arora et al. prove is not only are many derivative mathematical models impossible to compute, never mind in real time, because they require more computing power than the world possesses, the missing information to run a mathematical model is a very good place to cheat with.
