The O-ring model in economics offers an explanation of a production weakness.
The O-ring theory of economic development is a model of economic development put forward by Michael Kremer in 1993,[1] which proposes that tasks of production must be executed proficiently together in order for any of them to be of high value. The key feature of this model is positive assortative matching, whereby people with similar skill levels work together.[1]
The model argues that the O-ring development theory explains why rich countries produce more complicated products, have larger firms and much higher worker productivity than poor countries.[2]
The name is a reference to the 1986 Challenger shuttle disaster, a catastrophe caused by the failure of O-rings.
However, this model understates the possible results, as its production is thought to be positive. In communal markets, the weakest link can fail in their task and draw against the resources other teammates offer.
At Home Economics, we like to distinguish between two types of products: some are more conducive to private transactions, and others are more conducive to communal or public transactions. Those in the first category benefited greatly from the division of labor, for instance. Every worker in the chain focuses on one job, and the line produces a fabulous model T. The second category includes activities such as the ‘eyes on the street’ method of public safety, which was developed by urbanist Jane Jacobs. If a community is mindful of on-goings outside their front doors and reports as necessary, then residents benefit from reduced crime.
Now consider two forms of education delivery. Say one involves students completing modules of schoolwork from a home computer. The overall score of the class will harmed by the weakest link, but each individual performs independently. Now consider a classroom setting. Say one child often misses the bus. They regularly arrive late to class. This disrupts the teacher’s material delivery and causes friction between the students. In this communal situation, it is not only the tardy child who suffers but the whole class. This scenario is one most often given in explanation of why some high-poverty elementary schools suffer from below-average performance.
With items suited to private goods production, the o-ring model implies fewer products that meet perfection. If a company builds laptops and one worker fails to meet standards, fewer laptops are sold. But in a group scenario, where the leaders, perhaps of a certain age, are unwilling to adopt an electronic methodology, say a new accounting feature, they create more work for employees effectively pulling negative productivity.
The negative impact potential in the o-ring model for communal products is underestimated.
