"Dylan Matthews summarizes the The Case for Open Borders drawing on an excellent interview with Bryan Caplan. Here is one bit from the interview:On the economics, David Roodman has a characteristically careful and comprehensive review written for Givewell of the evidence on the effect of immigration on native wages. He writes, “the available evidence paints a fairly consistent and plausible picture”:Letting someone get a job is not a kind of charity. It’s not a welfare program. It’s just the government leaving people alone to go and make something out of their lives. When most people are on earth are dealt such a bad hand, to try to stop them from bettering their condition seems a very cruel thing to do to someone.My elevator pitch has no economics in it, because the economics is actually too subtle to really explain in an elevator pitch. If I had a little bit more time, I would say, “What do you think the effects for men have been of more women in the workforce?”Are there some men who are worse off? Sure. But would we really be a richer society if we kept half the population stuck at home? Isn’t it better to take people who have useful skills and let them do something with it, than to just keep them locked up someplace where their skills go to waste?Isn’t that not just better for them, but better for people in general, if we allow people to use their skills to contribute to the world instead of keeping them shut up someplace where they just twiddle their thumbs or do subsistence agriculture or whatever?
- There is almost no evidence of anything close to one-to-one crowding out by new immigrant arrivals to the job market in industrial countries. Most studies find that 10% growth in the immigrant “stock” changes natives’ earnings by between –2% and +2% (@Longhi, Nijkamp, and Poot 2005@, Fig 1; @Peri 2014@, Pg 1). Although serious questions can be raised about the reliability of most studies, the scarcity of evidence for great pessimism stands as a fact (emphasis added, AT)….
- One factor dampening the economic side effects of immigration is that immigrants are consumers as well as producers. They increase domestic demand for goods and services, perhaps even more quickly than they increase domestic production (@Hercowitz and Yashiv 2002@), since they must consume as soon as they arrive. They expand the economic pie even as they compete for a slice. This is not to suggest that the market mechanism is perfect—adjustment to new arrivals is not instantaneous and may be incomplete—but the mechanism does operate.
- A second dampener is that in industrial economies, the capital supply tends to expand along with the workforce. More workers leads to more offices and more factories. Were receiving economies not flexible in this way, they would not be rich. This mechanism too may not be complete or immediate, but it is substantial in the long run: since the industrial revolution, population has doubled many times in the US and other now-wealthy nations, and the capital stock has kept pace, so that today there is more capital per worker than 200 years ago.
- A third dampener is that while workers who are similar compete, ones who are different complement. An expansion in the diligent manual labor available to the home renovation business can spur that industry to grow, which will increase its demand for other kinds of workers, from skilled general contractors who can manage complex projects for English-speaking clients to scientists who develop new materials for home building. Symmetrically, an influx of high-skill workers can increase demand for low-skill ones. More computer programmers means more tech businesses, which means more need for janitors and security guards. Again, the effect is certain, though its speed and size are not.
- …one way to cushion the impact of low-skill migration on low-skill workers already present is to increase skilled immigration in tandem.
Plaudits are due to Givewell. While others are focused on giving cows, Givewell is going after the really big gains."
