Open Access and Dynamic Efficiency∗
نویسندگان
چکیده
We consider a model in which production of a downstream good requires access to an excludable upstream resource owned by a vertically integrated firm. The quality of the resource depends on an investment made by the owner and impacts the demand curve in the downstream market. Under open access, the owner must share the resource with downstream competitors at a regulated tariff, determined after the investment is made. We show that the owner’s investment exceeds the monopoly level if the access tariff is set according to a principle we call revenue neutrality. Revenue-neutral open access is consistent with current open access laws and requires only limited information on part of the regulator. Furthermore, quality increases with the number of entrants in the downstream market. Our results hence contradict the notion that dynamic efficiency must be sacrificed for gains in static (allocative) efficiency.

Open pit limit optimization using dijkstra’s algorithm
In open-pit mine planning, the design of the most profitable ultimate pit limit is a prerequisite to developing a feasible mining sequence. Currently, the design of an ultimate pit is achieved through a computer program in most mining companies. The extraction of minerals in open mining methods needs a lot of capital investment, which may take several decades. Before the extraction, the p...

In data grid, using reservation is accepted to provide scheduling and service quality. Users need to have an access to the stored data in geographical environment, which can be solved by using replication, and an action taken to reach certainty. As a result, users are directed toward the nearest version to access information. The most important point is to know in which sites and distributed sy...

Access control in open and dynamic Pervasive Computing Environments (PCEs) is a very complex mechanism and encompasses various new requirements. In fact, in such environments, context information should be used in access control decision process; however, it is not applicable to gather all context information completely and accurately all the time. Thus, a suitable access control model for PCEs...

متن کاملA context-sensitive dynamic role-based access control model for pervasive computing environments
Resources and services are accessible in pervasive computing environments from anywhere and at any time. Also, due to ever-changing nature of such environments, the identity of users is unknown. However, users must be able to access the required resources based on their contexts. These and other similar complexities necessitate dynamic and context-aware access control models for such environmen...
