Secondly encountering his textbook with @ojblanchard1 as a young student made me appreciate the power of elegant mathematical modelling to understand macroeconomic questions.

The topics covered and how they are discussed still relevant for macro today

His analysis in that speech was prescient on ways to prevent global contagion, post E.Asian crisis reserve accumulation & need for private sector buy-in.

Reading it 25+ years after publication reveals how forward-thinking and influential his analysis was for all that followed.

Yes think ultrasounds tap into making latent preferences more easily realised.

Wheras seems India in this dimension has started individual + community level shift in the value and potential seen in women.

*Ultrasound tech, possibly the non-military technology with the most gendered negative effects in recent history?

Yes,seems sig improvement esp given underlying parental /cultural incentives(& may be sign of that gradually shifting)
I like this by Jisoo Hwang which -Shows evolution across Asia & exceptionalism of S.Korea
-role of lower ratio in higher order births
-Decline in stated son preference in surveys

India stopping rules pretty strong which leads to relatively strong skew in last birth compared to others

Significant difference on wanting another child when comparing those with only boys vs only girls

Jayachandran(2023) great paper on progress and remaining inequities. Although sex ratio data at birth seems more volatile (possibly by trying to be retrospective)

-F/M ratio of infant survival marked improvement
-Eldest son preference pretty strong,when plotting non-eldest/eldest stunting rates

-Risk of crowding out,but empirically seems banks respond by issuing deposits not cutting lending.
Here is the case of Japan

-Jeanne(2024) have straightforward model showing bank balance sheet decisions interacting with gov debt issuance

-Some data on threshold of gov debt/GDP, after which greater issuance absorbed by banks

Here Craft has a wonderful analysis of Allen and Mokyr competing frameowrks for the 1st IR and role of micro and macro inventions(& overlapping definitions).

Crafts is also very clear on the evidence base required for thier arguments on first IR to be robust

I don’t even know what he’s done!

That whole Ukraine starlink thing blew over quite quickly.
Thought it would lead to some broader debates about outsourcing critical infrastructure to private companies
