In Memoriam: Robert Mundell

Robert Mundell passed away earlier this week. Most macroeconomics students will know of the Mundell-Fleming model, of course, while a lesser number may have heard of his work on optimum currency areas.

Here is a relatively old article about him from the New York Times:

”In the very short run, I’m a Keynesian,” he said. ”In the intermediate run, I’m a supply-sider, and in the long run I’m a monetarist.”

And here is a summary by The Economist on the impossible trilemma:

HILLEL THE ELDER, a first-century religious leader, was asked to summarise the Torah while standing on one leg. “That which is hateful to you, do not do to your fellow. That is the whole Torah; the rest is commentary,” he replied. Michael Klein, of Tufts University, has written that the insights of [[international macroeconomics]] (the study of trade, the balance-of-payments, exchange rates and so on) might be similarly distilled: “Governments face the policy trilemma; the rest is commentary.”

Here is Paul Krugman, first rhapsodizing about the Optimum Currency Area1:

First up, Mundell, whose classic 1961 paper argued that a single currency was more likely to be workable if the regions sharing that currency were characterized by high mutual labor mobility. (He actually said factor mobility, but labor is almost surely the one that matters). How so?

.. and then rhapsodizing about Robert Mundell and his early theoretical work:

Those of us who work on international monetary theory have been wondering for a decade when Robert Mundell would get his richly deserved Nobel Memorial Prize in Economic Sciences. Mundell’s work is so central to that field, so “seminal”–an overused term that really applies here–that on many disputed issues his ideas are the basis for both sides of the debate. But a layperson might be confused about exactly what Mundell and his prize are really about.

This is the NYT obituary:

In his 2006 interview, he said that winning the Nobel “was particularly pleasing to me as my work has been quite controversial and no doubt stepped on a lot of intellectual toes.”
He added: “Even more than that, when I say something, people listen. Maybe they shouldn’t, but they do.”

And finally, the Washington Post’s obit:

Dr. Mundell gave one of the more unusual — and crowd-pleasing — acceptance speeches in the history of the Nobel Prize. He ended his remarks by singing a few bars of the hit Frank Sinatra song “My Way,” an allusion to the independent-minded approach that he brought to his life and work.

Two articles from Bill Gates about Covid19 that are worth reading

The first is an AMA:

A therapeutic could be available well before a vaccine. Ideally this would reduce the number of people who need intensive care including respirators. The Foundation has organized a Therapeutics Accelerator to look at all the most promising ideas and bring all the capabilities of industry into play. So I am hopeful something will come out of this. It could be an anti-viral or antibodies or something else.

One idea that is being explored is using the blood (plasma) from people who are recovered. This may have antibodies to protect people. If it works it would be the fastest way to protect health care workers and patients who have severe disease.

And speaking of convalescent blood therapy, this is also worth reading:

A simple and medically feasible strategy is available now for treating COVID-19 patients, transfuse blood plasma from recovered patients. The idea is that the antibodies from the recovered patients will help the infected patients. The idea is an old one and has been used before with some success.

And this is the second article by Bill Gates, worth reading in full, and so I will not provide an excerpt. Consistently applied restrictions on movement across the entire country, a clear strategy on how to prioritize testing, and a clear plan on developing a treatment and a vaccine are the key takeaways. Applicable mostly to America, or written with America in mind, but really works across the entire planet. India has applied the first of these as well as she could have.
