Trump and Xi are both posturing ahead of their upcoming summit, but PRC/Xi is escalating - as noted by @rushdoshi.bsky.social and Lingling Wei this is because they think (rightly) Trump will back off.

Inflation is going to be higher in the US in the news few years than most are forecasting, @adamposen.bsky.social says.

Why the inflation impact of deportation has been lagged

If 1 million+ migrants have left, how has production stayed up?
No increase in native or legal employment in the sectors which are known to be heavy users of migrant labor

What is going on?
McKibbin, Noland, and Hogan (2024) says impact should be big and stagflationary
Substitution of K or L not there in the data
Mismeasurement of net migrant outflows?
Over-counting/claims of total deported?
Or workers and families take time to make up their minds on a wrenching decision
Not sure that ICE really will come for them
Head underground but keep working
Employers do not have to pay more or invest – in fact can end up paying less
Difficult to decide when to leave


Actual financial conditions are more relevant than FFR Inflation expectations are less well anchored

Recent past experience of higher inflation has a lasting impact (Gagnon and Kamin 2025)

Staggered salient price hikes are coming
Think like eggs under Biden
Beef, certain fruit and veg, musical instruments, toys…
De minimis imported goods
Some pharmaceuticals potentially
Energy depending upon the impact of AI demand
Durable goods (autos, furniture, construction inputs), though, are less salient for inflation perceptions
