Full Ronald Coase Biography
Ronald Harry Coase (b. December 29, 1910) is a British economist and the Clifton R. Musser Professor Emeritus of Economics at the University of Chicago Law School. After studying with the University of London External Programme in 1927-29, Coase entered the London School of Economics where he took courses with Arnold Plant. Coase graduated from the London School of Economics with a B.Sc. (Econ) in 1931, and earned his doctorate from the University of London in 1951. He emigrated to the United States that same year and started work at the University of Buffalo. In 1958 he moved to the University of Virginia. Coase settled at the University of Chicago in 1964 and became the editor of the Journal of Law and Economics. He received the Nobel Prize in Economics in 1991.
Coase's transaction costs approach is currently influential in modern organizational theory, where it was reintroduced by Oliver E. Williamson.
Coase is also often referred to as the "father" of reform in the policy for allocation of the electromagnetic spectrum, based on his article "The Federal Communications Commission" (1959) where he criticizes spectrum licensing, suggesting property rights as a more efficient method of allocating spectrum to users.
Another important contribution of Coase is the "Coase Conjecture": an informal argument that durable-goods monopolists do not have market power because they are unable to commit to not lowering their prices in future periods.
Since modern firms can only emerge when an entrepreneur of some sort begins to hire people, Coase's analysis proceeds by considering the conditions under which it makes sense for an entrepreneur to seek hired help instead of contracting out for some particular task.
The traditional economic theory of the time suggested that, because the market is "efficient" (that is, those who are best at providing each good or service most cheaply are already doing so), it should always be cheaper to contract out than to hire.
There is a natural limit to what can be produced internally, however. Coase notices a "decreasing returns to the entrepreneur function", including increasing overhead costs and increasing propensity for an overwhelmed manager to make mistakes in resource allocation. This is a countervailing cost to the use of the firm.
Coase argues that the size of a firm (as measured by how many contractual relations are "internal" to the firm and how many "external") is a result of finding an optimal balance between the competing tendencies of the costs outlined above. In general, making the firm larger will initially be advantageous, but the decreasing returns indicated above will eventually kick in, preventing the firm from growing indefinitely.
Other things being equal, therefore, a firm will tend to be larger:
- the less the costs of organizing and the slower these costs rise with an increase in the transactions organized.
- the less likely the entrepreneur is to make mistakes and the smaller the increase in mistakes with an increase in the transactions organized.
- the greater the lowering (or the less the rise) in the supply price of factors of production to firms of larger size.
The first two costs will increase with the spatial distribution of the transactions organized and the dissimilarity of the transactions. This explains why firms tend to either be in different geographic locations or to perform different functions. Additionally, technology changes that mitigate the cost of organizing transactions across space will cause firms to be larger--the advent of the telephone and cheap air travel, for example, would be expected to increase the size of firms.
Published in the Journal of Law and Economics in 1960, while Coase was a member of the Economics department at the University of Virginia, "The Problem of Social Cost" provided the key insight that it is unclear where the blame for externalities lies. The example he gave was of a rancher whose cattle stray onto the cropland of his neighbour. If the rancher is made to restrict his cattle, he is harmed just as the farmer is if the cattle remain unrestrained.
Coase argued that without transaction costs it is economically irrelevant who is assigned initial property rights; the rancher and farmer will work out an agreement about whether to restrict the cattle or not based on the economic efficiency of doing so. Property rights allocation will hence matter only in determining distribution.
With sufficient transactions costs however, initial property rights will have a non-trivial effect. From the point of view of economic efficiency, property rights should be assigned such that the owner of the rights wants to take the economically efficient action. To elaborate, if it is efficient not to restrict the cattle, the rancher should be given the rights (so that cattle can move about freely), whereas if it is inefficient to do so, the farmer should be given the rights over the movement of the cattle (so the cattle are restricted).
Coase is research advisor to the Ronald Coase Institute, an organization that seeks to build the study of markets, with particular support for researchers from underdeveloped countries. |
