The Economics of Networks

چکیده
We analyze the salient features of networks and point out the similarities between the economic structure of networks and the structure of vertically related industries. The analysis focuses on positive consumption and production externalities, commonly called network externalities. We discuss their sources and their effects on pricing and market structure. We distinguish between results that do not depend on the underlying industry microstructure (the "macro" approach) and those that do (the "micro" approach). We analyze the issues of compatibility, coordination to technical standards, interconnection and interoperability, and their effects on pricing and quality of services and on the value of network links in various ownership structures. We also briefly discuss the issue of interconnection fees for bottleneck facilities. * Plenary session address, E.A.R.I.E. conference, Chania, Greece, September 1994.

In knowledge-based economy, knowledge has a public good and non-rivalry nature. Firms build their own knowledge stock not only by means of internal R&D and collaboration with partners, but also by means of previously spilled over knowledge of other firms and public research laboratories (such as universities). Firms based on their absorptive capacity, and level of intra-industry and extra-indus...
متن کاملForecast of Iran’s Electricity Consumption Using a Combined Approach of Neural Networks and Econometrics
Electricity cannot be stored and needs huge amount of capital so producers and consumers pay special attention to predict electricity consumption. Besides, time-series data of the electricity market are chaotic and complicated. Nonlinear methods such as Neural Networks have shown better performance for predicting such kind of data. We also need to analyze other variables affecting electricity c...
