Optimal Local Exchange Carrier Size
نویسندگان
چکیده
Optimal firm size and patterns of returns to scale among the local exchange companies in the U.S. telecommunications industry are estimated for the years: 1975, 1978, 1981, 1984, 1987 and 1990. The independent companies display increasing returns to scale, while the Baby Bells display constant or decreasing returns to scale. The independent companies operate at a scale smaller than optimal size, while the Baby Bells operate at a scale greater than optimal size. Efficiencies can be gained by industry restructuring, by allowing independents to expand their size while the Baby Bells can be downsized to create smaller units.

Network-Wide Distributed Carrier Frequency Offsets Estimation and Compensation
In this paper, we propose a fully distributed algorithm for frequency offsets estimation in decentralized systems. With the proposed algorithm, each node estimates its frequency offsets by local computations and limited exchange of information with its direct neighbors. Such algorithm does not require any centralized information processing or knowledge of global network topology. It is shown an...
متن کاملThe Optimal Power Flow of Multiple Energy Carriers in Networked Multi-Carrier Microgrid
The future distribution network comprising different energy carriers will include small-scale energy resources (SSERs) and loads, known as a Networked multi-carrier microgrid (NMCMG). This concept not only leads to an efficient reduction in operation costs, but also encompasses the energy transformation between gas and electric networks at combined nodes, as well as district heating networks. I...
متن کاملUsing Neural Networks and Genetic Algorithms for Modelling and Multi-objective Optimal Heat Exchange through a Tube Bank
In this study, by using a multi-objective optimization technique, the optimal design points of forced convective heat transfer in tubular arrangements were predicted upon the size, pitch and geometric configurations of a tube bank. In this way, the main concern of the study is focused on calculating the most favorable geometric characters which may gain to a maximum heat exchange as well as a m...

Today, urbanization is growing in all countries. Increasing urban population growth has led to the development in various fields especially the economy. For example, according to the World Bank's World Development Report 2019, about 16% of world GDP is produced in the 30 cities in the world. But cities development has had many problems such as pollution, noise, traffic, etc. Accordingly many re...
متن کاملThe effect of government size on yields and stock prices in the Tehran Stock Exchange
Without government intervention, grow and achieve high levels of economic wealth is not achievable. Communities where a relatively high level of economic activity has been monopolized by the state, due to bureaucracy, rent-seeking, corruption and inefficiency, have failed to achieve significant economic growth. Easier to say that the involvement of zero or one hundred percent of the state's eco...
