Lectures on Macroeconomics Lectures on Macroeconomics provides the first comprehensive description and evaluation of macroeconomic theory in many years. While the authors' perspective ...

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.

Stanley Fischer— so many contributions but I want to highlight.

His speech on need for an international lender of resort which argued for IMF to play that role. Over time as $-funding has become more important, CB swap lines led by the Fed mimic part of that role

Possibly one dimension of Deepseek/ broader China success tech:

-Large share of STEM grads
-Increasing rates of MSc and Doctoral students
-Growing share of grads in finance as W growth outpaced national but still absolute # of talented STEM grads is large talent reservoir

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 think one child policy really just led a massive structural increase in ratio, helped by the diffusion of ultrasound tech*

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

How Chinese Goods ate the world…
Throwback to Feenstra et al(1998), examining growing US-China trade deficit back then(!) linking to
-Macro forces
-China crowding out East Asian imports
“By 1995, China has displaced South Korea as one of the top 5 suppliers of "apparel and other textile products"

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

So I will try to use this site with an oversupply of screenshots.

This shows how Gov Debt to GDP has evolved for a range of advanced economies, reaching extremely high levels.

An increasing share of that extra issuance absorbed by domestic banks, possibly a source of fin repression.

It’s fun posting currently both here and on Twitter as I can easily cope by pretending the low engagement is due to small audiences and declining Twitter engagement as Musk breaks the site down..

Rather than you know,my posts being bad.

This is what happens when you let a true nerd design central bank communication without any guidance from generalists.

Or you know the BoJ has no idea how to end this um great experiment in monetary policy

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

Since Crafts passing every few days I pick another random work of his to read at night before bed.

To add to Pseudos predictably good point, I’d add Crafts takes arguments of his opponents seriously & was devastatingly clear where they fell short.

Tonight’s reading was a review of Allen & Mokyr

That whole Ukraine starlink thing blew over quite quickly.

Remember when we used to judge people “selling out”?

Millennials have been hit by so many economic shocks that we now seem incapable of holding out celebrities,artists and sports people to any moral standard if it conflicts with $$$$

Looking through the graphs in central bank reports raises a challenge to the concept of ideas being non rivalrous and the fast diffusion of information in our modern era…

Some of them clearly have not heard of ggplot2
