This paper presents a model of two competing local telecommunications networks, similar in spirit to the model of Laffont, Rey and Tirole (1996). The networks have different attributes which we assume are fixed and the consumers have idiosyncratic tastes for these attributes. The networks are mandated to interconnect and the access charges are determined cooperatively in the first stage. In the...

We examine the gap in broadband access to the Internet between minority groups and white households with geographically fine data on DSL subscription. In addition to income and demographics, we also examine quality of service and competition as components of the Digital Divide. The gaps in DSL demand for blacks and Hispanics do not disappear when income, education, and other demographic variabl...

This paper builds on Cremer, Rey and Tirole’s analysis of the possible incentives of a firm with the largest share of installed-base customers, in a market characterized by strong network externalities, to degrade or refuse interconnection with its smaller rivals in order to gain a relative quality advantage in competing for new customers. We extend their model to allow any number of smaller ri...

image classification is an issue which utilizes image processing, pattern recognition and classification methods. automatic medical image classification is a progressive area in image classification and it expected to be more developed in the future. due to this fact that automatic diagnosis which use intelligent methods such as medical image classification can assist pathologists by providing ...

prediction, diagnosis, recovery and recurrence of the breast cancer among the patients are always one of the most important challenges for explorers and scientists. nowadays by using of the bioinformatics sciences, these challenges can be eliminated by using of the previous information of patients records. in this paper has been used adaptive nero fuzzy inference system and data mining techniqu...

A hybrid approach for intrusion detection in computer networks is presented in this paper. The proposed approach combines an evolutionary-based fuzzy system with an Ant Colony Optimization procedure to generate high-quality fuzzy-classification rules. We applied our hybrid learning approach to network security and validated it using the DARPA KDD-Cup99 benchmark data set. The results indicate t...

The most important issues in auction design are the traditional concerns of competition policy–preventing collusive, predatory, and entry-deterring behaviour. Ascending and uniform-price auctions are particularly vulnerable to these problems, and the Anglo-Dutch auction–a hybrid of the sealed-bid and ascending auctions–may often perform better. Effective anti-trust policy is also critical. Howe...

JEL codes: L51, L96 I examine the effects of FCC regulation on the innovation and introduction of advanced telecommunications services in the U.S. An interim of lighter regulation provides an “experiment” to test the regulatory regime’s impact on innovation. The econometric model comprises an arrival process (for service innovation) followed by a duration process (for regulatory delay). The num...

The relationship between technical progress and price competition is a controversial issue in economics. This paper highlights the fact that investment in technical progress is an authentic type of competition which benefits the consumers rather than the industry. This type of competition exists when the potential for technical progress, which can be incorporated by firms through investment, is...
