Does
#immigration
make

inventors emigrate?
The answer is both, but 85% of the effect is because migrating *makes* inventors more productive.
Talent is everywhere, opportunity is not!

Many good points here. Americans are always scared of the recent wave of newcomers, but they always integrate successfully—no matter where they come from.
In every way that I can see, Hispanic Americans seem to be following the same path toward integration into American society and culture that the Irish followed over a century earlier:

Why do we keep rolling the dice on which firms get talented people? Do we really want to randomly decide who gets to
#innovate
and
#grow
their business? And how much value do we destroy by keeping talent out?
Just to cite one example:
USCIS has received enough electronic registrations for unique beneficiaries during the initial registration period to reach the FY 25 H-1B cap. We have notified those who were randomly selected. For more information, visit:

It’s common to think that the decision to migrate is primarily an economic one. But it’s not. It’s fundamentally social.

Immigrants directly invent more than their expected share because they:
1. Are more productive over their career (graph 1)
2. Patent in more novel fields
3. Are more likely to move into highly productive tech hubs
4. Bring scientific knowledge from foreign countries (graph 2)

I’ve never used this platform to discuss my religious views. Today I’ll make an exception. Christ taught “love one another” and “blessed are the peacemakers”. I try to live by those words. Yesterday’s “Bible photo op” was cynical and antithetical to everything Jesus said and did.

For me, the most useful principle in finding work-life balance is this:
The scarce resource in research jobs isn't time. It's insight!
Therefore, we must seek to maximize the inputs that enhance our insight instead of maximizing time, which is not the most important input.

Any social scientist doing empirical work needs to know the

and
#causal
inference. Statistics alone are insufficient.
This paper helped me understand how that applies to my field (business strategy). 👇
Why should we study history and do historical social science?
Generically, because it is an intellectual pleasure. More specifically, because ahistorical thinking (aka presentism, short-termism) makes us miss out on many things. (repost)👇
