Kealey and Ricketts on Science as a Contribution Good

Two of my favorite writers on the economic organization of science, Terence Kealey and Martin Ricketts, have produced a recent paper on science as a “contribution good.” A contribution good is like a club good in that it is non-rivalrous but at least partly excludable. Here, the excludability is soft and tacit, resulting not from fixed barriers like membership fees, but from the inherent cognitive difficulty in processing the information. To join the club, one must be able to understand the science. And, as with Mancur Olson’s famous model, consumption is tied to contribution — to make full use of the science, the user must first master the underlying material, which typically involves becoming a scientist, and hence contributing to the science itself.

Kealey and Ricketts provide a formal model of contribution goods and describe some conditions favoring their production. In their approach, the key issue isn’t free-riding, but critical mass (what they call the “visible college,” as distinguished from additional contributions from the “invisible college”).

The paper is in the July 2014 issue of Research Policy and appears to be open-access, at least for the moment.

Modelling science as a contribution good
Terence Kealey, Martin Ricketts

The non-rivalness of scientific knowledge has traditionally underpinned its status as a public good. In contrast we model science as a contribution game in which spillovers differentially benefit contributors over non-contributors. This turns the game of science from a prisoner’s dilemma into a game of ‘pure coordination’, and from a ‘public good’ into a ‘contribution good’. It redirects attention from the ‘free riding’ problem to the ‘critical mass’ problem. The ‘contribution good’ specification suggests several areas for further research in the new economics of science and provides a modified analytical framework for approaching public policy.
