Vertical Disintegration
نویسنده
چکیده
With economies of scale, a vertically integrated firm can lower its upstream cost by supplying downstream competitors. The competitors may strategically choose not to purchase from the integrated firm, unless the latter’s price for the intermediate good is sufficiently lower than those of alternative suppliers. In a simple model of dynamic scale economies through learning by doing, equilibrium vertical disintegration occurs if and only if total industry profit is higher under vertical separation than under integration. The model bridges a logical gap in George Stigler’s classic theory on vertical organization, and sheds light on the widely observed phenomenon of vertical disintegration.

Vertical Integration and Operational Flexibility
The main aim of the paper is to highlight the relation between flexibility and vertical integration. To this purpose, we go through the selection of the optimal degree of vertical disintegration of a flexible firm which operates in a dynamic uncertain environment. The enterprise we model enjoys flexibility since it can switch from a certain amount of disintegration to vertical integration and v...
متن کاملThe Process of Vertical Dis-integration: an Evolutionary Perspective on Outsourcing
It is argued that an evolutionary perspective on firm boundaries with its strong focus on knowledge, as well as processes of search, learning and capability development is instrumental in developing a theory of firm boundaries that is close to managerial concerns. Building on insights in evolutionary economics, propositions are developed regarding scope, speed, and switching costs in the proces...
متن کاملDisintegration-of-measure Techniques for Commuting Multivariable Weighted Shifts
We employ techniques from the theory of disintegration of measures to study the Lifting Problem for commuting n-tuples of subnormal weighted shifts. We obtain a new necessary condition for the existence of a lifting, and generate new pathology associated with bringing together the Berger measures associated to each individual weighted shift. For subnormal 2-variable weighted shifts, we then fin...
متن کاملAgglomeration, Opportunism, and the Organization of Production
Recent economic analysis of outsourcing has focused on its international dimension. In contrast, this paper considers local outsourcing. The paper specifies and solves a model where the organization of production (vertically integrated or not) and the location of production (agglomerated or not) are jointly determined. The paper shows that agglomeration reduces opportunism, a thick market effec...
متن کاملThe effect of physician-hospital affiliations on hospital prices in California.
During the 1990s, a record number of U.S. hospitals entered into some form of vertical combination with physicians. During the same period, many integrated hospital-physician arrangements broke up. Using data from California, we investigate whether such vertical activity affected hospital pricing. We find that neither integration nor disintegration was associated with significant changes in pri...
