During the period 1929-34 a campaign forcing the repatriation of Mexicans and Mexican Americans was carried out in the U.S. by states and local authorities. The claim of politicians at the time was that repatriations would reduce local unemployment and give jobs to Americans, alleviating the local effects of the Great Depression. This paper uses this episode to examine the consequences of Mexican repatriations on labor market outcomes of natives. Analyzing 893 cities using full count decennial Census data in the period 1930-40, we find that repatriation of Mexicans was associated with small decreases in native employment and increases in native unemployment. These results are robust to the inclusion of many controls. We then apply an instrumental variable strategy based on the differential size of Mexican communities in 1930, as well as a matching method, to estimate a causal "average treatment effect." Confirming the OLS regressions, the causal estimates do not support the claim that repatriations had any expansionary effects on native employment, but suggest instead that they had no effect on, or possibly depressed, their employment and wages.

A steady stream of immigrants from Mexico, Central America, Asia, Africa, and the Middle East—a very different immigrant population than the Europeans who settled in the Midwest beginning more than 150 years ago—has slowed the hollowing out of the region’s bigger cities and small factory towns in recent decades. In most of the Midwest today, immigrants are a major source—and in some communities the only source—of population and new business growth. According to the Chicago Council on Global Affairs, from 2000 to 2015, non-native born populations in Midwest metros grew 34 percent (more than 1 million people), and accounted for 37 percent of all Midwest communities’ population growth. From Racine and Janesville, Wis. in the west, to Akron, Ohio and Erie, Pa. in the east, growth in immigrant populations has compensated for losses or outpaced modest growth of native-born populations.

Pakistan/Libhya/Iran

Amazing why the Bushies concentrate so much energy on Iran when a country WITH nukes, Islamic fundamental terrorist camps, IED's happening not infrequently, is undergoing this much upheaval

On another route, why don't more people talk about what occurred with Libya and nukes. This is a country with definite proof of direct terrorist attacks against civilians, a "crazy" leader, and a nuclear program who without a bullet being fired gave up his nuclear program in exchange for some normalization of international relations all through negotiation.

A post which I wish I would have written first

Krugman on the wholesale lunacy of some of the right wing blogosphere going after a 12 year old kid:

Politics aside, the Graeme Frost case demonstrates the true depth of the health care crisis: every other advanced country has universal health insurance, but in America, insurance is now out of reach for many hard-working families, even if they have incomes some might call middle-class.

And there’s one more point that should not be forgotten: ultimately, this isn’t about the Frost parents. It’s about Graeme Frost and his sister.

I don’t know about you, but I think American children who need medical care should get it, period. Even if you think adults have made bad choices — a baseless smear in the case of the Frosts, but put that on one side — only a truly vicious political movement would respond by punishing their injured children.

While the facts seem to clearly make the case that the Frosts have made choices that are essentially good ones for a family to make: work two jobs, stay together with kids who are handicapped by illness. They've been ridiculed for taking federal help instead of making other "choices" - Like not selling there home (well duh move to worse neighborhood) or sending there disabled kid to a public school (when the tuition at the private school is covered by the state secondary to the child's disability). It's important to remember that they didn't choose to have there kids be in a car accident (and thus basically prevent them from getting any affordable health insurance secondary to preexisting conditions). Finally, it's just as important to remember these are still children and as a society no matter the decisions of parent we should give ALL kids a reasonable chance to succeed and making sure kids are healthy is essential to that
