Here’s a clear, accurate summary of Paul Collier’s views on immigration, mostly based on his book Exodus: How Migration Is Changing Our World and his subsequent essays/interviews. Collier’s position is not nativist or restrictionist in the typical sense — he accepts that immigration can be beneficial — but he is sharply critical of high-scale, unmanaged migration flows. His arguments are mostly framed in terms of social cohesion, institutional quality, and the long-run stability of both sending and receiving countries.

Below is a structured synthesis of his main arguments.

==== 1. Immigration is neither uniformly good nor uniformly bad ====

Collier pushes back against both:
* The libertarian/economic-optimist view (“migration is always a win-win”), and
* The conservative populist view (“migration is harmful or dangerous”).

He argues that immigration has complex externalities that standard economic models ignore, especially:
* impacts on social norms,
* trust,
* reciprocity,
* and the social contract.

==== 2. The “diaspora dynamic”: why migration tends to accelerate ====

One of his most distinctive ideas is the diaspora dynamic.
* Migration becomes self-reinforcing: once a diaspora from a country forms, it becomes easier for new migrants to settle (lower costs, familiar networks).
* As a result, migration volume can grow exponentially, even when the labor-market need or absorptive capacity is stable or shrinking.
* This can produce assimilation stress in receiving countries and brain drain in sending countries.

Collier sees this as the reason why “open borders” is unsustainable: because migration doesn’t stabilize—it's dynamic and increases in attractive countries.

==== 3. Social cohesion, norms, and trust are crucial ====

Collier believes rich societies work well because they have:
* high interpersonal trust
* a stable social contract
* shared norms and mutual obligations

He argues that large-scale migration from culturally distant societies can weaken these if assimilation is slow:

: “People owe obligations to those with whom they feel a sense of shared identity.”

His concern isn’t cultural purity, but institutional fragility: he thinks these norms underpin the functioning of high-trust states (e.g., Scandinavia).

==== 4. Assimilation is the key — and volume determines its success ====

Collier’s central claim:

: Assimilation can work, but it is sensitive to scale and speed.

High migration rates can outpace the ability of newcomers to integrate or for host societies to maintain shared norms.

He supports:
* moderate inflows
* strong emphasis on assimilation (language, norms, civic expectations)
* avoiding “parallel societies”

He is opposed to:
* very high or rapid inflows
* multiculturalism-as-separation (i.e., separate norms)

==== 5. Immigration can harm poor countries ====

Collier believes:
* The loss of skilled workers from poor nations (“brain drain”) can prevent institutional development.
* Diasporas can help development, but only up to a point.
* Very high emigration rates trap poor countries in low-development equilibria by exporting their talent base.

He thinks:
* Rich countries should be mindful about draining doctors, engineers, bureaucrats from fragile states.

==== 6. The poor in receiving countries may lose from migration ====

He argues that:
* Immigration generally benefits the average citizen through lower prices and specialization.
* But the bottom 20% of native workers face wage pressures, competition for housing, and competition for social services.

Collier emphasizes distributional consequences, not just aggregate effects.

==== 7. Refugees are different — prioritize genuine refugees ====

Collier is more pro-refugee than pro-economic migration.

His view:
* Refugees should be protected, but ideally closer to their home countries, where integration is faster and return is possible.
* Europe's current asylum system encourages dangerous journeys and enriches smugglers.

He advocates:
* much more funding for refugee protection in neighboring states
* fewer incentives for irregular civil asylum systems
* clearer differentiation between refugees and economic migrants

==== 8. Policy prescription: “Moderate, selective, integrative” immigration ====

Collier supports:
* Moderate immigration rates
* Selective migration that avoids harming poor countries
* Strong assimilation efforts
* Tightened low-skill immigration if it harms low-wage natives

And a general opposition to very high-volume migration or open borders.

==== 9. His overall thesis in one sentence ====

: Immigration can be good, but only at levels and speeds consistent with assimilation, institutional stability, and benefits for both host and origin countries — and modern rich countries frequently exceed those levels.
