Powering China
This title was first published in 2002: This study of the Chinese electric power industry examines the ownership and the restructuring of the industry. The reform of the electric power industry is also seen as part of the wider economic development that has been taking place in China, thus providing fresh perspectives on the changes taking place in both the economy and society more generally. Presenting a wealth of extensive research on the subject, the book elucidates the power struggle between political and bureaucratic elite and explains the sensitive and volatile relationship between the central and provincial government against an increasingly complex global background.
Regulation and Development
Author: Jean-Jacques Laffont
language: en
Publisher: Cambridge University Press
Release Date: 2005-03-10
In Regulation and Development Jean-Jacques Laffont provides the first theoretical analysis of regulation of public services for developing countries. He shows how the debate between price-cap regulation and cost of service regulation is affected by the characteristics of less developed countries (LDCs) and offers a positive theory of privatization that stresses the role of corruption. He develops a new theory of regulation with limited enforcement capabilities and discusses the delicate issue of access pricing in view of LDC's specificities. In the final chapter he proposes a theory of separation of powers which reveals one of the many vicious circles of underdevelopment made explicit by the economics of information. Based on organization theory and history, and using simple empirical tests wherever possible, Professor Laffont offers a comprehensive evaluation of the different ways to organize the regulatory institutions and opens up a rich new research agenda for development studies.
Analysis and Transceiver Design for the MIMO Broadcast Channel

This book deals with the optimization-based joint design of the transmit and receive filters in MIMO broadcast channel in which the user terminals may be equipped with several antenna elements. Furthermore, the maximum performance of the system in the high power regime as well as the set of all feasible quality-of-service requirements is analyzed. First, a fundamental duality is derived that holds between the MIMO broadcast channel and virtual MIMO multiple access channel. This duality construct allows for the efficient solution of problems originally posed in the broadcast channel in the dual domain where a possibly hidden convexity can often be revealed. On the basis of the established duality result, the gradient-projection algorithm is introduced as a tool to solve constrained optimization problems to global optimality under certain conditions. The gradient-projection tool is then applied to solving the weighted sum rate maximization problem which is a central optimization that arises in any network utility maximization. In the high power regime, a simple characterization of the obtained performance becomes possible due to the fact that the weighted sum rate utility converges to an affine asymptote in the logarithmic power domain. We find closed form expressions for these asymptotes which allows for a quantification of the asymptotic rate loss that linear transceivers have to face with respect to dirty paper coding. In the last part, we answer the fundamental question of feasibility in quality-of-service based optimizations with inelastic traffic that features strict delay constraints. Under the assumption of linear transceivers, not every set of quality-of-service requirements might be feasible making the power minimization problem with given lower bound constraints on the rate for example infeasible in these cases. We derive a complete description of the quality-of-service feasibility region for arbitrary channelmatrices.
