Fixing the Peer Review Process by Crowdsourcing It?

Try the following experiment. Take any article accepted for publication at any journal. Now  submit it to another journal. What are odds it will be accepted as is? Zero. There is even a pretty good chance it will be rejected. Our profession seemingly believes that its published articles are in fact not good enough to publish!

That’s from forthcoming editorial (link opens a .pdf) in the Review of Financial Studies by the Yale School of Management’s Matthew Spiegel.

Spiegel’s point is that editors and reviewers should stop chasing perfection. No paper is or will ever be perfect. For Spiegel, the real peer review process begins after an article has been published:

There is almost no reason to worry if a particular article is “right.” What horrors will befall us if a paper with a mistaken conclusion is published? Not many. The vast majority of articles are quickly forgotten. Who cares if their findings are accurate? The profession will not use the material regardless. What if an article is important — that is, people read and cite it? In that case, academics will dissect its every aspect. Some will examine the article’s data filters; others will check for coding errors; still others will look for missing factors or reverse causality explanations. The list is endless. But, that is the point. The list is endless. Authors, referees, and editors cannot even scratch the surface. Nor do they have to. The fact that our colleagues will stress test any important publication means our profession’s received canon of knowledge has a self-correcting mechanism built in. We have faith that important articles are “right” because their results have been tested over and over again in myriad ways.

A recent example of the vetting process described by Spiegel relevant to development economics is that of David Roodman and Jonathan Morduch failing to replicate failing to replicate earlier findings by Mark Pitt and Shahidur Khandker.

Beyond the Market, Part 2: Market Paradoxes

Yesterday, I discussed Robert Neuwirth’s book Stealth of Nations: The Global Rise of the Informal Economy, which emphasizes the activities of “illegal street vendors and unlicensed roadside hawkers.”

I concluded by noting how that brought to mind a few conversations I’d recently had with a friend who was observing how, relative to Asia and Africa, few people actually knew how to hustle in America nowadays.

In my Law, Economics, and Organization seminar, I use an old textbook by Milgrom and Roberts. By “old,” I mean that it was the textbook used to teach economics of organization when I was in college. By “old,” I mean that the book is as old as some of my younger students. But I use it because it’s a classic, and because it covers just about everything one needs to know about law and economics and the economics of organization.

Market Paradoxes

In their book, Milgrom and Roberts highlight a first important paradox of markets (I am paraphrasing):

Beyond the Market, Part 1: Hustle and Flow

I am teaching my Law, Economics, and Organization class this semester. The class is for upper-level undergraduates and graduate students, so there is a good variety of backgrounds and interests among the students who enroll in it.

Since the class is a seminar, I spend about half the time teaching, with the other half spent discussing specific papers.

Last Friday, in the context of the module on relational contracts, we discussed two classic papers. The first is Greif’s (1993) paper, in which he discusses the various mechanisms used by 11th-century Jewish merchants around the Mediterranean to sustain long-distance trade. The second is Bernstein’s (1992) investigation of how diamond traders choose to “opt out” of the legal system by developing their own extra-legal institutions.

Hustle and Flow

In the spirit of both articles, I wanted to link to a somewhat dated article in Wired,  a Q&A with Robert Neuwirth, who published a book titled Stealth of Nations: The Global Rise of the Informal Economy last fall. Here is an excerpt:
