Analysis of transaction costs
|Awards||Nobel Prize in Economics (1991)|
Ronald Harry Coase (//; born 29 December 1910) is a British-born, America-based 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. He received the Nobel Memorial Prize in Economics in 1991.
Coase is best known for two articles in particular: "The Nature of the Firm" (1937), which introduces the concept of transaction costs to explain the nature and limits of firms, and "The Problem of Social Cost" (1960), which suggests that well-defined property rights could overcome the problems of externalities (see Coase Theorem). 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. Additionally, Coase's transaction costs approach is currently influential in modern organizational economics, where it was reintroduced by Oliver E. Williamson.
Ronald Harry Coase was born in Willesden, a suburb of London, on 29 December 1910. His father was a telegraphist for the post office, as was his mother before marriage. As a child, Coase had a weakness in his legs, for which he was required to wear leg-irons. Due to this problem, he attended the school for physical defectives. At the age of 12, he was able to enter the Kilburn Grammar School on scholarship. At Kilburn, Coase completed the first year of his B.Comm degree and then passed on to the University of London. Coase married Marion Ruth Hartung of Chicago, Illinois in Willesden, England, August 7, 1937.
Coase attended the London School of Economics, where he received a bachelor of commerce degree in 1932, and was a member of the staff from 1935 to 1951. He then started to work at the University at Buffalo and became an American citizen after moving to the United States in the 1950s. 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 was also for a time a Trustee of the Philadelphia Society. He received the Nobel Prize in Economics in 1991.
As his 100th birthday approached, Coase was working on a book concerning the rise of the economies of China and Vietnam. An interview with Coase was conducted by Wang Ning (co-author of the book How China Became Capitalist) December 28–29, 2010, in Chicago. In the interview, Coase explained the mission of the Coase China Society and his vision of economics and the part to be played by Chinese economists. Coase was honored and received an honorary doctorate from the University at Buffalo department of economics in May of 2012.
The Nature of the Firm 
In The Nature of the Firm (1937) - a brief but highly influential essay - Coase attempts to explain why the economy features a number of business firms instead of consisting exclusively of a multitude of independent, self-employed people who contract with one another. Given that "production could be carried on without any organization [that is, firms] at all", Coase asks, why and under what conditions should we expect firms to emerge?
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 (in the tradition of Adam Smith) 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.
Coase noted, however, a number of transaction costs involved in using the market; the cost of obtaining a good or service via the market actually exceeds the price of the good. Other costs, including search and information costs, bargaining costs, keeping trade secrets, and policing and enforcement costs, can all potentially add to the cost of procuring something from another party. This suggests that firms will arise which can internalise the production of goods and services required to deliver a product, thus avoiding these costs. This argument sets the stage for the later contributions by Oliver Williamson: markets and hierarchies are alternative coordination mechanisms for economic transactions.
There is a natural limit to what a firms can produce internally, however. Coase notices "decreasing returns to the entrepreneur function", including increasing overhead costs and increasing propensity for an overwhelmed manager to make mistakes in resource allocation. These factors become countervailing costs 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 lower the costs of organizing and the slower these costs rise with an increase in the number of 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 smaller 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 may allow firms to become larger — the advent of the telephone and of cheap air travel, for example, would be expected to increase the size of firms.
Coase does not consider non-contractual relationships, such as those between friends or family-members.
The Problem of Social Cost 
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 the initial assignment of property rights makes no difference to whether or not the farmer and rancher can achieve the economically efficient outcome. If the cost of restraining cattle by, say, building a fence, is less than the cost of crop damage, the fence will be built. The initial assignment of property rights determines who builds the fence. If the farmer is responsible for the crop damage, the farmer will pay for the fence (as long the fence costs less than the crop damage). If the rancher is responsible for the crop damage, the rancher will build the fence. The allocation of property rights is primarily an equity issue, with consequences for the distribution of income and wealth, rather than an efficiency issue.
With sufficient transaction costs, initial property rights matter for both equity and efficiency. 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 efficient to restrict the cattle, the farmer should be given the rights over the movement of the cattle (so the cattle are restricted).
Coase Conjecture 
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.
The Ronald Coase Institute 
Coase is research advisor to the Ronald Coase Institute, an organization that promotes research on the institutions – the laws, rules, customs, and norms – that govern real economic systems, with particular support for young scholars from developing and transitional countries.
Coase coined the well known, but often misquoted adage "If you torture the data long enough, it will confess."
