One of these is not like the others and it represents a dangerous new expansion in Trump's tariff adventures, meddling in internal criminal matters in other countries.

The “marathon” part of doing a PhD continues to be the easiest one. Now, off to winter break at home.

Fascinating paper on where 6000 global elites went to college. Billionaires, CEOs, heads of state, central bankers, etc.

In a word: Harvard.

Fully 10% of global elites went to Harvard. Elite US schools are over-represented (23% IvyPlus), but nobody comes close to Harvard.

Astonishing reminder that I live and work among a very non random sample of the population.
Among U.S. nationals, it’s even more stark. Harvard represents 16% of elites — literally off the chart. 3/N

Let me put it this way: in Brazil, we lived for a couple of decades in the “I’ve never heard the name of the head of the Army” land that Americans take for granted. Then Bolsonaro dragged us to the world of “General X would probably join a coup, but I guess General Y wouldn’t”. Not a good place…

Hello blue skies!

I am a 2nd-year PhD student in economics at Stanford. I am interested in labor and public topics in developing countries. In particular, unemployment and taxation with high informality.

I am from Brazil and use my free time to run! Currently preparing for my 4th marathon.
