Professor Niall Ferguson. AP Images Harvard professor and famous historian Niall Ferguson reportedly made some bizarre and offensive remarks about economist John Maynard Keynes at an investment conference yesterday.

According to financial writer Tom Kostigen, the editor at large of Private Wealth and Financial Advisor magazines, Ferguson made two startling suggestions about Keynes at the Tenth Annual Altegris Conference in Carlsbad, California:

Keynes' economic philosophy, Ferguson reportedly suggested, was the result of Keynes not caring about future generations.

Keynes didn't care about future generations, Ferguson reportedly suggested, because Keynes was gay and did not have children.

Dan Jamieson at Investment News, also reported the remarks.

Specifically, Kostigen reported the following:

[I]n front of a group of more than 500 investors, Ferguson responded to a question about Keynes' famous philosophy of self-interest versus the economic philosophy of Edmund Burke, who believed there was a social contract among the living, as well as the dead. Ferguson asked the audience how many children Keynes had. He explained that Keynes had none because he was a homosexual and was married to a ballerina, with whom he likely talked of "poetry" rather than procreated. The audience went quiet at the remark. Some attendees later said they found the remarks offensive. ...

Ferguson, who is the Laurence A. Tisch Professor of History at Harvard University, and author of The Great Degeneration: How Institutions Decay and Economies Die, says it's only logical that Keynes would take this selfish worldview because he was an "effete" member of society. Apparently, in Ferguson's world, if you are gay or childless, you cannot care about future generations nor society.

Not surprisingly, Kostigen's report has already drawn considerable attention to, and criticism of, Ferguson. We have reached out to Professor Ferguson for comment. We will update this article when we hear from him. (UPDATE: Professor Ferguson has responded with a full apology, describing his remarks as "stupid and tactless." His email is below.)

In addition to the offensive suggestion that those who don't have children don't care about the future or society, Professor Ferguson's reported remarks are bizarre and insulting to Keynes on two levels.

John Maynard Keynes. Wikimedia Commons First, this is the first time we have heard a respectable academic tie another economist's beliefs to his or her personal situation rather than his or her research. Saying that Keynes' economic philosophy was based on him being childless would be like saying that Ferguson's own economic philosophy is based on him being rich and famous and therefore not caring about the plight of poor unemployed people.

Second, Keynes' policies did not suggest that he did not care about future generations. On the contrary. ... For the sake of both future generations and current generations, Keynes believed that governments should run deficits during recessions and then run surpluses during economic booms. Politicians have never seemed to be able to follow the second part of Keynes' proscription — they tend to run deficits at all times — but it seems unfair to blame this latter failing on Keynes.

Ferguson is not the first person to suggest that Keynes did not care about the future, and this sentiment is normally tied to one of Keynes' most famous sayings:

"... In the long run, we are all dead."

Importantly, however, in saying this, Keynes was in no way suggesting that the future doesn't matter. Rather, when this remark is read in context, it is clear that Keynes was chiding economists for ducking responsibility for their own lousy short-term predictions:

In the long run we are all dead. Economists set themselves too easy, too useless a task if, in tempestuous seasons, they can only tell us that when the storm is long past the ocean is flat again.

So if Ferguson is basing his assertion that Keynes didn't care about the future on this line, his remark is even more unfair.

For those who are new to the larger economic debate that is the backdrop to these remarks, here's a snapshot:

Professor Ferguson and other economists have been loudly and consistently warning for years that the deficit spending and debts of most developed countries will eventually end in disaster. Professor Ferguson and other "austerians" suggest that governments should immediately cut spending and balance their budgets, even if this results in a brutal short-term recession and exploding unemployment.

This "austerian" philosophy has been countered by the "Keynesian" philosophy advocated by Paul Krugman and others in which governments enact stimulus and run big deficits during weak economic periods to offset weak private-sector spending and help shore up employment, consumer spending, and social well-being until the private sector recovers. High debts and deficits are a long-term concern that needs to be addressed, Krugman says, but they do not constitute a near-term crisis that requires immense, self-inflicted, short-term pain to alleviate.

In the past five years, the experience of many countries suggests that Krugman's philosophy is correct, and, as yet, none of the doom predicted by Ferguson and other austerians has come to pass. Meanwhile, countries like the U.K. and Greece, which have cut spending to try to balance their budgets, have been mired in multiple recessions (or, in the case of Greece, a depression). And, notably, because lower economic output leads to less tax revenue, these countries have not made much progress in balancing their budgets.

Ferguson's reported remarks would represent a new low in the war of words between these economic camps, and they could be very damaging to his reputation. As yet, the remarks have not been confirmed, and we eagerly await Professor Ferguson's response.

*UPDATE: Professor Ferguson has responded to our questions with a full apology. In a tweet (and below), he describes his remarks about Keynes as "stupid and tactless." His email is below.

During a recent question-and-answer session at a conference in California, I made comments about John Maynard Keynes that were as stupid as they were insensitive.

I had been asked to comment on Keynes’s famous observation “In the long run we are all dead.” The point I had made in my presentation was that in the long run our children, grandchildren and great-grandchildren are alive, and will have to deal with the consequences of our economic actions.

But I should not have suggested – in an off-the-cuff response that was not part of my presentation – that Keynes was indifferent to the long run because he had no children, nor that he had no children because he was gay. This was doubly stupid. First, it is obvious that people who do not have children also care about future generations. Second, I had forgotten that Keynes’s wife Lydia miscarried.

My disagreements with Keynes’s economic philosophy have never had anything to do with his sexual orientation. It is simply false to suggest, as I did, that his approach to economic policy was inspired by any aspect of his personal life. As those who know me and my work are well aware, I detest all prejudice, sexual or otherwise.

My colleagues, students, and friends – straight and gay – have every right to be disappointed in me, as I am in myself. To them, and to everyone who heard my remarks at the conference or has read them since, I deeply and unreservedly apologize.
