The rise and fall of debate in economics..

Food for thought post by Joe Francis, an Argentina economy specialist (a country whose economics must be keeping him both busy and amused).

He says how econs do not discuss any more:

Once upon a time, economists regularly used to publicly criticise each other’s work in academic journals. But not any more.

In Figure 1 I have illustrated the degree to which economists have stopped debating. The data have been culled from Jstor, the online database of academic journals. To estimate the number of debating articles for each year, I searched for articles with “comment”, “reply”, and/or “rejoinder” in their titles, as these are the key words used to indicate a comment on someone else’s article and a reply to that comment. I did the search for the five most prestigious economics journals. I then used the total number of articles in those five journals in each year as the denominator.

Figure 1 shows how there was a dramatic increase in the level of debate in economics from the 1920s through the 1960s. Then, however, there was an equally dramatic fall. At the peak level, in 1968, fully 22 per cent of the articles published in these journals appear to have been related to debate. By 2013, however, just 2 per cent were.

Why did this rise and fall happen?

The rise in the debates began in the 1930s, presumably as economists suffered from pangs of Great Depression-inspired doubt. Keynes did most to increase the level of debate, while the strength of Marxist ideas must also have played an important part in encouraging a culture of cantankerousness. Paul M. Sweezy, North America’s leading Marxist economist, for instance, contributed to the debates in these journals (see Sweezy 1950a, 1950b, 1972).

The decline in debate then appears to have been associated with the emergence of a ‘neoliberal’ hegemony from the 1970s onwards. Keynesianism wilted, while Marxists were forced back into their niche publications. It is notable, for example, that Robert Pollin, arguably North America’s leading Marxist economist today, has only ever published one, six-page article in any of these journals (see Pollin 1985).

The rise, then, was associated with the challenges to the old liberal orthodoxy, while the decline has been accompanied by the establishment of a new liberal orthodoxy. That, at least, would be my rough sketch of what happened.

The question then becomes whether it mattered. In my opinion, a lack of debate would not matter if economists had successfully answered all the questions they are supposed to ask. Recent events, however, suggest that they may not have done.

There is hardly any room for debate. Certain colleges dominate the space with a standard school of thought. Anything which opposes their view is just rejected.

Though, this is just one way of figuring discussions. May be with advent of internet, blogging etc econs have shifted their discussions to other more instant channels. Replies to journal articles takes a long time and may never be published. But one can always express assent and dssent right away on one’s blog/website/twitter handle.
