The reason is not hard to fathom. Hobbled by severe damage to private and public-sector balance sheets, and with policy interest rates at or near zero, post-bubble economies have been mired in a classic “liquidity trap.” They are more focused on paying down massive debt overhangs built up before the crisis than on assuming new debt and boosting aggregate demand.

Shinzo Abe's Monetary-Policy Delusions by Stephen S. Roach - Project Syndicate - 0 views

The sad case of the American consumer is a classic example of how this plays out. In the years leading up to the crisis, two bubbles – property and credit – fueled a record-high personal-consumption binge. When the bubbles burst, households understandably became fixated on balance-sheet repair – namely, paying down debt and rebuilding personal savings, rather than resuming excessive spending habits.CommentsView/Create comment on this paragraph

Like Japan, America’s post-bubble healing has been limited – even in the face of the Fed’s outsize liquidity injections. Household debt stood at 112% of income in the third quarter of 2012 – down from record highs in 2006, but still nearly 40 percentage points above the 75% norm of the last three decades of the twentieth century. Similarly, the personal-saving rate, at just 3.5% in the four months ending in November 2012, was less than half the 7.9% average of 1970-99.

The Eurozone's Delayed Reckoning by Nouriel Roubini - Project Syndicate - 0 views
-
For starters, the European Central Bank’s “outright monetary transactions” program has been incredibly effective: interest-rate spreads for Spain and Italy have fallen by about 250 basis points, even before a single euro has been spent to purchase government bonds.
-
The introduction of the European Stability Mechanism (ESM), which provides another €500 billion ($650 billion) to be used to backstop banks and sovereigns, has also helped, as has European leaders’ recognition that a monetary union alone is unstable and incomplete, requiring deeper banking, fiscal, economic, and political integration.

But, perhaps most important, Germany’s attitude toward the eurozone in general, and Greece in particular, has changed. German officials now understand that, given extensive trade and financial links, a disorderly eurozone hurts not just the periphery but the core.

Moreover, balkanization of economic activity, banking systems, and public-debt markets continues, as foreign investors flee the eurozone periphery and seek safety in the core.

The US is also a large transfer union, in which richer states permanently subsidize the poorer ones.

But the fundamental crisis of the eurozone has not been resolved, and another year of muddling through could revive these risks in a more virulent form in 2014 and beyond.

"The Euro's Latest Reprieve" by Joseph E. Stiglitz | Project Syndicate - 0 views

Like an inmate on death row, the euro has received another last-minute stay of execution. It will survive a little longer. The markets are celebrating, as they have after each of the four previous “euro crisis” summits – until they come to understand that the fundamental problems have yet to be addressed.

Europe’s leaders have finally understood that the bootstrap operation by which Europe lends money to the banks to save the sovereigns, and to the sovereigns to save the banks, will not work.

What is now proposed is recapitalization of the European Investment Bank, part of a growth package of some $150 billion. But politicians are good at repackaging, and, by some accounts, the new money is a small fraction of that amount, and even that will not get into the system immediately. In short: the remedies – far too little and too late – are based on a misdiagnosis of the problem and flawed economics.

Eurobonds and a solidarity fund could promote growth and stabilize the interest rates faced by governments in crisis. Lower interest rates, for example, would free up money so that even countries with tight budget constraints could spend more on growth-enhancing investments.

One more summit: The crisis rolls on | vox - 0 views
-
The summit attendees seem to have successfully drawn the conclusion that this was necessary from the disastrous impact of their mid-June decision on new lending to Spanish authorities to shore up their banks. Within hours, the main conclusion drawn by the markets was that the Spanish public debt had grown by €100 billion, bringing Spain closer to the fate of Ireland (bad bank debt dragging down a government with an otherwise healthy fiscal position).

The new agreement suggests that in the future, banks will be bailed out by the collective effort of Eurozone countries.
-
First, this arrangement is to be finalised by the end of the year. This means that, in the end, the Spanish debt will rise by €100 billion (the market participants who enthusiastically celebrated the decision by raising the price of Spanish bonds will eventually understand that). Ditto in the not unlikely case that some Italian or French banks wobble before December.
-
Second, conditions will be attached to such a rescue. These recommendations could be clever if they require “Swedish-style” bank restructuring whereby shareholders and other major stakeholders are made to absorb first the losses, and if a new clearly untainted management replaces the previous one. Such interventions limit the costs to taxpayers; they can even turn a profit. Of course, the conditions could also be silly, raising the costs to taxpayers to huge levels.
-
Third, the arrangement is linked to the establishment of a “single supervisory mechanism involving the ECB”. This could be a single Eurozone supervisor built inside the ECB, which would go a long way to plugging one the worst mistakes in the Maastricht Treaty (lack of a joint regulation and resolution regime for banks).
-
But this is not what the official text says, which makes one suspect that policymakers have not agreed to something simple and clean. Most likely, they will keep negotiating and come with the usual 17-headed monster that exhausted diplomats are wont to invent.
-
This is important because a contagious banking crisis that hits several large banks would require much more money than is available in the EFSF-EMS facilities.

Light conditionality, as they requested, is bound to collapse at the foot of the Bundestag, which must approve every single loan.

There was no knock-out winner in this summit, but on points I’d have to say that the winner is the crisis.

There was nothing on collapsing Greece, nothing on unsustainable public debts in several countries, and no end in sight to recession in an increasing number of countries.

o how to measure the Internet’s contribution to our lives? A few years ago, Austan Goolsbee of the University of Chicago and Peter J. Klenow of Stanford gave it a shot. They estimated that the value consumers gained from the Internet amounted to about 2 percent of their income — an order of magnitude larger than what they spent to go online. Their trick was to measure not only how much money users spent on access but also how much of their leisure time they spent online.

Fluctuations in the world’s economies are largely due to the stories we hear and tell about them. These popular, emotionally relevant narratives sometimes inspire us to go out and spend, start businesses, build new factories and office buildings, and hire employees; at other times, they put fear in our hearts and impel us to sit tight, save our resources, curtail spending, and reduce risk. They either stimulate our “animal spirits” or muffle them.

How Jean Tirole's Work Helps Explain the Internet Economy - NYTimes.com - 0 views

Many Internet companies, for instance, give their products away free, which means that antitrust law built on pricing is irrelevant. But a result is they grow so fast that they can quickly become monopolies.
-
“He’s helping us think about what is one of the greatest challenges of our time, how to deal with what feel like friendly monopolists,” said Tim Wu, a Columbia Law School professor who studies Internet policy and antitrust. “Amazon, Google and the others give us all this stuff for free or lower prices, so we love them, but are they dangerous in ways we don’t always see?”
-
In the 2002 paper with Jean-Charles Rochet, Mr. Tirole defined two-sided markets, or markets that “get both sides on board” by charging more to one set of customers in order to increase demand by others.
-
In the tech industry, it explains why Google, Facebook and Twitter offer their services free – the more people who use them, the more advertisers they can attract. Likewise, Amazon lowered the price of its new phone to 99 cents in part because smartphones succeed when they have a lot of apps – and developers won’t want to build apps for Amazon’s phone unless a lot of people are using it.
-
-
For regulators, tech companies have been a riddle in part because they do not follow the behavior of typical monopolies: Many do not charge for their products, and companies that offer entirely different products are nonetheless competitors. For instance, Google’s chairman, Eric Schmidt, argued in a speech on Monday that Google’s biggest competitor in search is Amazon and in mobile is Facebook — even though neither one is a search engine.
-
“Inspired by him and others like him, our effort was to try to move beyond the traditional understanding of something like an aluminum cartel who just raised their prices on aluminum and everything got more expensive,” said Mr. Wu, who was a senior adviser to the Federal Trade Commission on antitrust matters.

For consumers, the costs include absorbing advertisers’ ad spending by paying more for their products, being tracked and shown personalized ads, and giving up privacy.

Then the observers talk with the teacher about what has just taken place. Each public lesson poses a hypothesis, a new idea about how to help children learn.

The research showed that Japanese students initiated the method for solving a problem in 40 percent of the lessons; Americans initiated 9 percent of the time.

Similarly, 96 percent of American students’ work fell into the category of “practice,” while Japanese students spent only 41 percent of their time practicing.
