Paul Krugman:
Stupid China Stories: So a stock crash in China triggered a big decline around the world..., why should events in China matter for the rest of us?
Well, you and I might think that it's because China is a pretty big economy... So when China slumps, you can and should expect knock-on effects elsewhere.
But trust the Republican field to declare that it's all Obama's fault. Scott Walker wants Obama to cancel a state dinner with Xi; Donald Trump says that it's because Obama has let China "dictate the agenda" (no, I have no idea what he thinks he means). And Chris Christie says that it's because Obama has gotten us deep into China's debt.
Actually, let's play a bit with that last one, OK? You could, conceivably, tell a story in which America becomes dependent on Chinese loans; then, when China gets in trouble, it demands repayment, pushing us into crisis too. But any story along those lines has a corollary: we should be seeing a spike in US interest rates as our credit line gets pulled. What you actually see is falling rates: ...
Oh, why am I even bothering?...

Nothing particularly surprising here -- the Great recession was unusually severe and unusually long, and hence had unusual impacts, but it's good to have numbers characterizing what happened:
Great Recession Job Losses Severe, Enduring: Of those who lost full-time jobs between 2007 and 2009, only about 50 percent were employed in January 2010 and only about 75 percent of those were re-employed in full-time jobs.
The economic downturn that began in December 2007 was associated with a rapid rise in unemployment and with an especially pronounced increase in the number of long-term unemployed. In "Job Loss in the Great Recession and its Aftermath: U.S. Evidence from the Displaced Workers Survey" (NBER Working Paper No. 21216), Henry S. Farber uses data from the Displaced Workers Survey (DWS) from 1984-2014 to study labor market dynamics. From these data he calculates both the short-term and medium-term effects of the Great Recession's sharply elevated rate of job losses. He concludes that these effects have been particularly severe.

Of the workers who lost full-time jobs between 2007 and 2009, Farber reports, only about 50 percent were employed in January 2010 and only about 75 percent of those were re-employed in full-time jobs. This means only about 35 to 40 percent of those in the DWS who reported losing a job in 2007-09 were employed full-time in January 2010. This was by far the worst post-displacement employment experience of the 1981-2014 period.
The adverse employment experience of job losers has also been persistent. While both overall employment rates and full-time employment rates began to improve in 2009, even those who lost jobs between 2011 and 2013 had very low re-employment rates and, by historical standards, very low full-time employment rates.
In addition, the data show substantial weekly earnings declines even for those who did find work, although these earnings losses were not especially large by historical standards. Farber suggests that the earnings decline measure from the DWS is appropriate for understanding how job loss affects the earnings that a full-time-employed former job-loser is able to command.
The author notes that the measures on which he focuses may understate the true economic cost of job loss, since they do not consider the value of time spent unemployed or the value of lost health insurance and pension benefits.
Farber concludes that the costs of job losses in the Great Recession were unusually severe and remain substantial years later. Most importantly, workers laid off in the Great Recession and its aftermath have been much less successful at finding new jobs, particularly full-time jobs, than those laid off in earlier periods. The findings suggest that job loss since the Great Recession has had severe adverse consequences for employment and earnings.

From the NBER Digest:
Thinking, Fast and Slow: Efforts to Reduce Youthful Crime in Chicago: Interventions that get youths to slow down and behave less automatically in high-stakes situations show positive results in three experiments.

Disparities in youth outcomes in the United States are striking. For example, among 15-to-24 year olds, the male homicide rate in 2013 was 18 times higher for blacks than for whites. Black males lose more years of potential life before age 65 to homicide than to heart disease, America's leading overall killer. A large body of research emphasizes that, beyond institutional factors, choices and behavior contribute to these outcomes. Those choices include decisions around dropping out of high school, involvement with drugs or gangs, and how to respond to confrontations that could escalate to serious violence.
In "Thinking, Fast and Slow? Some Field Experiments to Reduce Crime and Dropout in Chicago" (NBER Working Paper No. 21178), authors Sara B. Heller, Anuj K. Shah, Jonathan Guryan, Jens Ludwig, Sendhil Mullainathan, and Harold A. Pollack explain these behavioral differences using the psychology of automaticity. Because it is mentally costly to think through every situation in detail, all of us have automatic responses to some of the situations we encounter. These responses—automaticity—are tuned to situations we commonly face.
The authors present results from three large-scale, randomized experimental studies carried out in Chicago with economically disadvantaged male youth. All three experiments show sizable behavioral responses to fairly short-duration, automaticity-reducing interventions that get youths to slow down and behave less automatically in high-stakes situations.
The first intervention (called Becoming a Man, or BAM, developed by Chicago-area nonprofit Youth Guidance) involved 2,740 males in the 7th through 10th grades in 18 public schools on the south and west sides of the city. Some youths were offered an automaticity-reducing program once a week during school or an after-school sports intervention developed by Chicago nonprofit World Sport Chicago. The authors find that participation in the programming reduced arrests over the program year for violent crimes by 44 percent, and non-violent, non-property, non-drug crimes by 36 percent. Participation also increased engagement with school, which the authors estimate could translate into gains in graduation rates of between 7 and 22 percent.
A second study of BAM randomly assigned 2,064 male 9th and 10th graders within nine Chicago public high schools to the treatment or to a control condition. The authors found that arrests of youth in the treatment group were 31 percent lower than arrests in the control group.
The third intervention was delivered by trained detention staff to high-risk juveniles housed in the Cook County Juvenile Temporary Detention Center. The curriculum in this program, while different from the first two interventions, also focused on reducing automaticity. Some 5,728 males were randomly assigned to units inside the facility that did or did not implement the program. The authors found that those who received programming were about 16 percent less likely to be returned to the detention center than those who did not.
The sizable impacts the authors observe from all three interventions stand in stark contrast to the poor record of many efforts to improve the long-term life outcomes of disadvantaged youths. As with all randomized experiments, there is the question of whether these impacts generalize to other samples and settings. The interventions considered in this study would not be costly to expand. The authors estimate that the cost of the intervention for each participant in the first two studies was between $1,178 and $2,000. In the third case, the per-participant cost was about $60 per juvenile detainee. The results suggest that expanding these programs may be more cost-effective than other crime-prevention strategies that target younger individuals.
The authors also present results from various survey measures suggesting the results do not appear to be due to changes in mechanisms like emotional intelligence or self-control. On the other hand results from some decision-making exercises the authors carried out seem to support reduced automaticity as a key mechanism. The results overall suggest that automaticity can be an important explanation for disparities in outcomes.

 What' causing so much instability in the world economy?
A Moveable Glut, by Paul Krugman, Commentary, NY Times: What caused Friday's stock plunge? What does it mean for the future? Nobody knows, and not much. ...
Still, investors are clearly jittery..., the world as a whole still seems remarkably accident-prone. ... But why does the world economy keep stumbling? ...
More than a decade ago, Ben Bernanke famously argued that a ballooning U.S. trade deficit was the result, not of domestic factors, but of a "global saving glut": a huge excess of savings over investment in China and other developing nations... He worried a bit about the fact that the inflow of capital was being channeled, not into business investment, but into housing; obviously he should have worried much more. ...
Of course, the boom became a bubble, which inflicted immense damage when it burst. Furthermore, that wasn't the end of the story. There was also a flood of capital from Germany and other northern European countries to Spain, Portugal, and Greece. This too turned out to be a bubble, and the bursting of that bubble in 2009-2010 precipitated the euro crisis.
And still the story wasn't over. With America and Europe no longer attractive destinations, the global glut went looking for new bubbles to inflate. It found them in emerging markets... It couldn't last, and now we're in the middle of an emerging-market crisis...
So where does the moving finger of glut go now? Why, back to America, where a fresh inflow of foreign funds has driven the dollar way up, threatening to make our industry uncompetitive again
What's ... important now is that policy makers take seriously the possibility, I'd say probability, that excess savings and persistent global weakness is the new normal.
My sense is that there's a deep-seated unwillingness, even among sophisticated officials, to accept this reality. Partly this is about special interests: Wall Street doesn't want to hear that an unstable world requires strong financial regulation, and politicians who want to kill the welfare state don't want to hear that government spending and debt aren't problems in the current environment.
But there's also, I believe, a sort of emotional prejudice against the very notion of global glut. Politicians and technocrats alike want to view themselves as serious people making hard choices — choices like cutting popular programs and raising interest rates. They don't like being told that we're in a world where seemingly tough-minded policies will actually make things worse. But we are, and they will.
