This Brief introduces the wireless spectrum market and discusses the current research for spectrum auctions. It covers the unique properties of spectrum auction, such as interference relationship, reusability, divisibility, composite effect and marginal effect, while also proposing how to build economic incentives into the network architecture and protocols in order to optimize the efficiency of wireless systems. Three scenarios for designing new auctions are demonstrated. First, a truthful double auction scheme for spectrum trading considering both the heterogeneous propagation properties of channels and spatial reuse is proposed. In the second scenario, a framework is designed to enable spectrum group secondary users with a limited budget. Finally, a flexible auction is created enabling operators to purchase the right amounts of spectrum at the right prices according to their users’ dynamic demands. Both concise and comprehensive, Auction Design for the Wireless Spectrum Market is suited for professionals and researchers working with wireless communications and networks. It is also a useful tool for advanced-level students interested in spectrum and networking issues.

Globally, most workers live precarious lives. In this examination of China's industrial relations since 1949, Xiaojun Feng explores why this should be. China provides an important case to examine this question because it has gone through both socialist revolution and marketized reforms, the major economic and political dynamics that have shaped the world since the twentieth century. Developing a comprehensive analytical framework for the interpretation of archives, interviews and participant observation, Feng explores the causes of and potential remedies for labour precarity in China. Bridging the 1949 and 1978 divides, this study unveils continuities and more fundamental discontinuities across these watershed moments, and sheds fresh light on the extent to which popular policy can counter labour precarity and the future dynamics of labour movements.
