International Migration as a Structural Transformation Policy

In today's blog, I discuss 3 ways for international migration to be part of a structural transformation policy: 1) as an industry itself; 2) training people abroad in the skills to develop a new industry at home; and 3) through immigration (eg Start-up Chile) blogs.worldbank.org/en/impacteva...

Anas al-Sharif, prominent Al Jazeera correspondent, among five journalists killed in Israeli airstrike on Gaza Israel admits deliberate attack on the journalist, known for frontline coverage, in a strike on a tent outside al-Shifa hospital

Israel has normalised killing journalists, like it normalised killing medical workers, like it normalised destroying hospitals and schools, like it normalised killing the equivalent of a classroom of children per day.

As an Israeli political scientist, I resisted thinking this war was a genocide. Here's what changed my mind The incitement for genocide in the Israeli public sphere is undeniable. So why are so many of us liberal Jews so reluctant?

Israeli political scientist Lihi Ben Shitrit:

"The more I learn about genocide, the more shocked and embarrassed I am by my own ignorance. Once I actively tried to be better informed about genocide, the picture in Gaza became terrifyingly clear."

Without immediate intervention, the last reporters in Gaza will die
July 21, 2025

AFP has been working with 1 writer, 3 photographers and 6 videographers, all freelance, in the Gaza Strip since its staff journalists left in 2024.

Along with a few others, they are now the only ones left to report what is happening in the Gaza Strip. The international press has been banned from entering the territory for nearly two years.

We refuse to watch them die.

One of them, Bashar, has been working with AFP since 2010, first as a fixer, then freelance photographer, and since 2024, as lead photographer. On July 19th he managed to post a message on Facebook: “I no longer have the strength to work for the media. My body is thin and I can’t work anymore.”

Bashar, 30, works & lives in the same conditions as all Gazans, moving from one refugee camp to another under Israeli bombings. For > a year he’s lived in utter destitution, working at extreme risk to his life. Hygiene is a major issue for him, with recurring bouts of severe intestinal illness.

Since Feb, Bashar’s been living in the ruins of his home in Gaza City with his mother, 4 brothers & sisters and the family of one of his brothers. Their house is devoid of any furnishings, except a few cushions. On Sunday morning, he reported that one of his brothers had “fallen, due to hunger.”

Even though these journalists receive a monthly salary from AFP, it’s no longer enough to buy food, or they have to pay completely exorbitant prices. The banking system has collapsed, and those who exchange money via online bank accounts charge a commission of up to 40%.

AFP no longer has the ability to provide them with a vehicle and there is not enough fuel to allow these journalists to travel for their reporting. Driving a car means becoming a target for Israeli airstrikes. AFP reporters therefore travel on foot or by donkey cart. (alt txt continued in next post)

our abstract: While many studies of public opinion in authoritarian regimes rely on list experi-
ments to overcome sensitivity bias, we show in this paper that a different technique,
the crosswise variant of the randomized response design, has superior performance
at measuring latent opposition to authoritarian regimes with fewer assumptions.
To show the power of this design, we randomly assigned a panel of 924 Tunisian
survey respondents to receive either a direct question about support for Tunisian
President Kais Saied or a randomized response question. Our results reveal that
between 10% to 30% of Tunisians oppose the president but would not report this
opposition on a direct question. We further employed a Bayesian parameterization
of the randomized response design to decompose the sensitivity bias and model
latent opposition and bias as a function of survey covariates. We find that ideolog-
ical and policy disagreement with the president strongly predicts latent opposition,
but that these same measures are negatively related to sensitivity bias. As a result,
we show that respondents who are ideologically closer to the president–that is, the
moderate opposition–tend to be more afraid of reporting their resistance to the
regime than the more radical opposition.
