Is America focusing on the wrong type of Trade?

Interesting paper on parallel currency markets in Nigeria using 9 years of daily data forthcoming at NBER Int'l Seminar on Macro by Toni Oki & Olalekan Bello. Parallel market affecting import prices, official market affecting expected inflation. https://t.co/KZvUwqxcHa

That's an interesting political-economy observation. Alexander Hamilton wanted government debt in part to create a politically powerful class that would precommit the government to repay its debts. Things have changed.

The strongest predictor wasn't a better algorithm.

It was better information.

A four-country study finds that simple mobile phone records can help identify chronic poverty — even where traditional survey data are scarce or outdated. https://t.co/lOds7OBNIV

Finding trade data is one challenge. Understanding what those data mean for policy is another.

For policy makers everywhere wondering about their vulnerabilities to all-out economic warfare, Iran’s narrow waterway is not the only trade infrastructure chokepoint. Consider next what arrives by air.

Does Europe want better paid jobs in Morocco, paid for by China, creating more African demand for European goods?

Or do they want to see Moroccan labour move to Europe instead?

Europe has to decide

But if they want to see industrialisation in Africa, it will involve China

Somebody finally told them about the effective rate of protection? Nah. Just more politics❗️

[Olivier Blanchard @ojblanchard1]

On the Krugman et al/Aghion et al discussion. Working my way through it.

The easy part. Let’s settle the central issue, the measurement of productivity growth, i.e. the rate of change of output per hour.

There can be no question that the best measure of the rate of change of output is obtained by using chain indexes. This is what advanced countries, the US and European countries do. (slight difference between the US and other: Fisher versus Laspeyres indexes. Not irrelevant for the question at hand, as the two can differ when one sector, say AI, experiences sharp decreases in prices. But, I believe, not serious enough an issue to change conclusions) Quality adjustments vary across countries, but it is not clear how they bias the comparison between the US and Europe.

Main point re discussion: No reason whatsoever to use anything else (such as PPP prices) than the national measures of productivity growth.

Implication: Almost surely, productivity growth is lower in Europe than in the US.

This does not settle the issue of how to compare levels (as opposed to growth rates) between the US and Europe, or what this implies for the relative standards of living (and the role of terms of trade, and the potential for immiserizing growth in the US). More on those later.

The authors analyze 125,000 US households' transactions to measure how 2025 tariffs affected spending. Tariffs passed through 15-20% to retail prices, raising affected-good prices 1-2%. But households cut spending by 3 to 4 times the price increase. (1/3) https://t.co/tigAbc3M2y
