Williamson, Oliver E. 1981. "The Economics of Organization: The Transaction Cost Approach." American Journal of Sociology 87:548-577.
The transaction cost approach regards the transaction as the basic unit of analysis and holds that understanding of transaction cost economizing is central to the study of organizations through assessing how their governance structures serve to economize on these transaction costs.
II. Some rudiments
"A transaction occurs when a good or service is transferred across a technogically separable interface". Is the transaction easy and harmonious, or are their frequent misunderstandings and delays? Transaction cost analysis is about the comparative costs of planning, adapting, and monitoring task completion under alternative governance structures" p. 552
This theory presupposes that human agents are subject to bounded rationality and that some agents are given to opportunism. But for bounded rationality, all economic exchange could be efficiently organized by contract. And people can also be dishonest in economic transactions. "A different way of saying it is that while organizational man is computationally less competent than economic man, he is motivationally more complex".
In a perfect market opportunism can be avoided and punished over time, but not when there are small numbers of exchangers.
The critical dimensions for transactions are 1) uncertainty 2) frequency, 3)degree of durability
Asset specificity is important because it means that future trades are tied to this transaction, when specifics about the trader become important in deciding who to trade with. Asset specificity can be related to site, physical asset, and human asset (i.e. learned knowledge as a result of the transaction).
"The reason asset specificity is critical is that, once an investment has been made, buyer and seller are effectively operating in a bilater (or at least quasi-bilateral) exchange relation for a considerable period thereafter.
III. Efficient Boundaries
Decided what transactions are to be included in the organization effectively defines the organizaitonal boundary.
If assets are nonspecific, markets enjoy advantages in both production cost and governance cost respects; static scale economies can be more fully exhausted by buying instead of making; markets can also aggregate uncorrelated demands, thereby realizing risk-pooling benefits; and external procurement avoids many of the hazards to which internal procruement is subject". p. 558
The advantages of firms over markets are:
* internal organization are able to invoke fiat to resolve differences
* better access to information
Incentive to shift transactions inside the firm increases with uncertainty. Some examples are the Fischer body company and GM, forward integration into distribution
IV. Managing Human Assets: The Employment Relation
According to transaction-cost approach, "skills acquired in a learning-by-doing fashion and imperfectly transferable across employees need to be embedded in a protective governence structure......
Human assets can also be measured by 1) degree of firm-specificy and 2) difficulty of individual productivity measurability Low of 1 and 2 is a internal spot labor market. Low 1/High 2 is a primative team. High 1/Low 2 is an obligational market with defined rules for performance. High1/High 2 is the relational team where assets are specific and individual output hard to measure.
Comparisons with Organizational Literature
There are so many organizational types because each is optimized for different types of transactions. Unlike the abstract population ecology model, it offers predictions as to which particular organizations will have superior properties in which circumstances.
Williamson and Thompson agree on both coordination costs and the importance of the technical core, but he doesn't define measurable quantities for his variables.
Power is rather tautological and can be applied to anything.
Governance structures that have better transactional cost economizing properties will eventually displace those that have worse.
