What we’ve learned from the euro crisis, part I. Tyler Cowen

Matt Yglesias serves up a short and partial list, here are some of mine:
1. When the Germans say “no LOLR” they mean “no LOLR”!  Especially when they put it into print.  I already knew that, actually.
2. It is a disaster and a dead-end situation when a country uses its automatic stabilizers in a manner which supports rent-seeking and harms growth.  There is, in a time of crisis, no way out of the resulting trap.
3. The “regulation and labor law will come down really hard on larger firms” approach of Mediterranean Europe is far worse than we had thought, and we thought it was bad in the first place.  I can’t stress this point enough.  It’s cut those countries off from some major sources of growth and technical advance.
4. Don’t borrow in someone else’s currency.
5. Don’t think that “don’t borrow in someone else’s currency” is the only lesson.  Last I checked the Netherlands was doing OK.
6. International coordination doesn’t work very well unless the interests of the various countries are aligned in the first place.  If this is what becomes of the EU, what is our chance to save the world’s fish stocks?  Protect against global environmental problems?  etc.  The EU, and the eurozone, is designed for vague statements of consensus that, when faced with real problems, don’t get the job done.
7. We can suddenly imagine the so-called “first world” splitting into two parts, distinguished by the degree of conscientiousness applied to human capital formation.
8. The French-German marriage was never going to last that long anyway.  Yet without it, how do things get done in Europe?
9. The Mediterranean social welfare state model, based on lots of inefficient regulation, rent-seeking, reckless borrowing, and privilege within the local professions, is neither resilient nor robust.  It is wrong to blame “welfare states,” but it is also wrong to let “welfare states” off the hook altogether.  We’re learning a lot about how not all welfare states are created equal.
11. Hayek really was right about French rationalist constructivism (see chapter one).  I’m not sure there has been a better example in all of human history.
12. I’ll write more on Italy soon and what we can learn from the country in particular.  And I’ve left off some of the now-obvious, such as “no monetary union with a common fiscal authority and bank resolution mechanism,” etc.

How poverty has tracked global population. Felix Salmon

The world officially hit 7 billion people today, and so to celebrate I decided to take a look at what’s happened to poverty in the world as its population has increased — many, many thanks to Nick Rizzo and to Laurence Chandy and Homi Kharas at Brookings, two Englishmen who provided him with unpublished data and were extremely generous with their time.
The big picture can be seen in the chart at left: the number of poor people hasn’t been growing nearly as fast as the number of people. And indeed over the past 24 years, as the world’s population increased by 40% from 5 billion to 7 billion, the total number of people living in poverty has actually gone down. (One small note I should make about these charts: the dollar-a-day figures from 1987 onwards actually measure the population living on less than $1.25 a day, so a jump in the absolute-poverty numbers between 1974 and 1987 is partially a function of the fact that we’re raising the bar from $1 to $1.25.)
In fact, there’s pretty much the same number of people living in absolute poverty today — about 890 million, or 12.7% of the global population — as there were all the way back in 1804, when the world’s population hit 1 billion and 84% of them were living in absolute poverty.
Indeed, back in 1804, only 5% of the world was living on more than $2 a day. (All these numbers, of course, are real, and adjusted for purchasing power.) Today, that number is 4.7 billion, or 67% of the world’s population. The number of people in the world living out of poverty has been growing faster than the world’s population as a whole for pretty much all of recorded history.
And the “global middle” — people living on somewhere between $10 and $100 per day — is growing particularly fast. It was 1.14 billion in 1987; it’s 1.96 billion today. That’s an increase of 72%, even as the population of the world as a whole has gone up by just 40%.

In Egypt, the stakes have risen. Ahdaf Soueif


The Egyptian revolution of 25 January, as we all know, had no leaders. But in the course of its unfolding, and in the months since, a number of people have emerged who are pushing it forward, advocating for it and articulating its principles. Alaa Abd El Fattah, the activist and blogger (and my nephew) who has been jailed by the military prosecutor in Cairo pending trial, is one of those. And in his character and the role he’s adopted, he embodies some of the core aspects of the Egyptian revolution.
Alaa is a techie, a programmer of note. He and Manal, his wife and colleague, work in developing open-source software platforms and in linguistic exchange. They terminated contracts abroad and flew home to join the revolution. In Tahrir he moved between groups; listening, facilitating, making peace when necessary, defending the square physically when he had to.
He started the TweetNadwa series – the corporeal meetings of the Twitter community. In one of those, in Tahrir, I understood the remarkable role he played. We sat on the ground, a screen displaying rolling tweets, discussing the restructuring of Mubarak’s brutal security apparatus. Comments and questions could only use two minutes. If you liked what you heard you fluttered your raised hand. Passersby stopped and, intrigued, they stayed and contributed. The numbers grew to over a thousand from every background: enabled, together, working out ways forward, and Alaa in the middle, facilitating, directing, articulating, engaged, and passionate. I thought: this is leadership.
As arguments raged around who should write the new constitution, Alaa started a project to get “the people” to describe their dream Egypt. In June he wrote in the well-respected Egyptian daily, Shorouk: “What is the value of a constitution formulated without the real participation of the people? The proposals coming from our coalition of elites are catastrophic. They propose … that the constitution should appoint the army [as] protector of the civil nature of the state; that is to allow an institution with wide repressive powers and a history of interfering in government to be free of any supervision by any elected body.”
In a May blog he’d questioned the legitimacy of conscription if conscripts were used as a workforce for commercial ventures rather than to defend the country. But he was to enter a major confrontation with the military when, on 9 October, a peaceful (mainly Coptic) protest was attacked by the army and, worried, Alaa went looking for his friend, the activist Mina Daniel. He found him in the Coptic hospital, among the dead.
Alaa and his friends then did something remarkable; from the morgue they took on the entire system. In the face of the hospital issuing death certificates from “natural causes” they persuaded the stricken families to demand autopsies. Activist lawyers pressured the public prosecutor to order them. They fetched the coroner and his staff and persuaded them to carry out the autopsies in the presence of physicians whom they trusted. And then they sat them individually with the families to explain the reports to them.
The hospital morgue only had three drawers, so all the while they treated the bodies of their comrades with ice and fans, and they treated the anger, grief and suspicion of the families with tears and embraces and explanations. Thus they foiled the attempt to cause sectarian violence, and to get rid of the evidence of the bodies, and they mobilised the families to demand an investigation.
On 20 October, Alaa described the experience in Shorouk; the spirits of the murdered in the morgue, he wrote, “fought against the authority of the priests and sheikhs of the ruler who suggest that if you seek justice in this world you renounce it in the next, they fought against the Mubarak sectarianism that made the poor find enemies in the poor rather than in those who steal the bread from the poor.” Within 48 hours Alaa had been summoned to the military prosecutor. The army has, since February, court martialled 11,697 civilians. In February, Mona Seif founded and has since led the No Military Trials for Civilians campaign; Alaa is her brother.
Alaa has refused to be tried by a military court. He argues that he should not be held on remand; he was abroad and returned and presented himself to the court. Manal is due to deliver their first baby, Khaled, in a few days. He clearly intends to stay, in Cairo, at home. But the prosecutor jailed him for 15 days, and extended this for another 15 today .
The campaigners are working for every person jailed – but there’s a sense that the military have now upped the stakes. No one believes that the military believe the charges they’ve levelled against Alaa; in attacking this central, charismatic figure they appear to be openly mounting an attack on the very spirit of the revolution. It is because of the seriousness of this message that the protests in Egypt and in – so far – 23 cities across the world have been so immediate and so intense. And that Alaa’s mother, my sister, Laila Soueif, is on a hunger strike, which others are joining.
The implications of the jail extension – for human rights and the safety of Egypt’s young people – are enormous. But the depth and strength of the reaction against this also shows that the revolution could receive a kickstart once again.

What Occupy Wall Street is getting totally wrong. Steve Chapman


Ten years ago, the richest person on Earth couldn't buy a device that does what the iPhone does. Today, anyone can get one free upon signing a two-year carrier contract. Entry-level cars are vastly better in amenities and reliability than your father's Cadillac decades ago.

Lifesaving and life-changing medicines and therapies once unknown are now commonplace. Food costs a fraction of what it once did. TV viewers used to have three channels to choose from. Now they have hundreds.

Un material que se autorrepara a temperatura ambiente.


Un gel puede repararse a sí mismo simplemente poniendo en contacto las superficies de rotura. El material es capaz de autorrepararse incluso después de cinco días de haber sufrido el daño expuesto a un ambiente rico en oxígeno, en ausencia de luz y a temperatura ambiente.

Un gel es básicamente una estructura tridimensional sólida que alberga un líquido. El gel de ducha es un ejemplo, pero la gelatina comestible se aproxima más a la idea de gel técnico. La combinación de plasticidad y estructura sólida los hace candidatos ideales en el desarrollo de materiales inteligentes.

Los materiales autorreparadores tienen la capacidad de repararse a sí mismos cuando sufren un daño. Esta es una característica importante en los implantes médicos o en dispositivos astronáuticos. Los materiales inteligentes que presentan esta característica la consiguen por dos vías, bien por química supramolecular del tipo interacciones huésped-hospedador, que son muy rápidas pero muy sensibles a la presencia de agua, o por enlaces covalentes específicos, tolerantes al agua y a otros grupos funcionales competidores, pero que requieren un aporte energético (luz, calor o ambos) para reconstruir los enlaces.

Se deduce de lo anterior que la química del material inteligente autorreparador ideal es aquella en la que la reparación se produce sin estimulación y no depende de condiciones especiales del entorno, más allá del contacto físico de las superficies a reparar.

Un paso en esta dirección lo ha dado el equipo encabezado por Keiichi Imato, de la Universidad Kyushu (Japón), al conseguir una molécula con capacidad de entrecruzamiento, es decir, de formar redes tridimensionales, que puede dividirse formando un par de radicales, moléculas muy reactivas por tener electrones desparejados.
