such formulas. We show that the potential gains of such multi-antenna systems over single-antenna systems is rather large under independence assumptions for the fades and noises at different receiving antennas.

an in-depth study of the impact and potential gains of trade facilitation. In this report, results from both previous studies, international as well as national, and the experiences of the Swedish business community and individual companies of various sizes and types have been compiled and analysed

This paper reviews much of the scientific literature on the market for corporate control. The evidence indicates that corporate takeovers generate positive gains, that target firm shareholders benefit, and that bidding firm shareholders do not lose. The gains created by corporate takeovers do

design is rooted in the theory of network coding. Prior work on network coding is mainly theoretical and focuses on multicast traffic. This paper aims to bridge theory with practice; it addresses the common case of unicast traffic, dynamic and potentially bursty flows, and practical issues facing

for this state of affairs is that existing theories of work The authors express great appreciation to members of the consulting firm that helped us gain access to the organizations where this research was conducted; to Kenneth Brousseau, Daniel Feldman, and Linda Frank for assistance in data collection

1 Measuring potential gains from specialization under non-convex technologies*

around the world converged on Seattle with the goal of launching a new round of trade negotiations under the auspices of the World Trade Organization (WTO). This has been dubbed “WTO2000 ” in recognition of the new millennium. In light of the tremendous growth in world trade over the last fifty years— much of it fueled by multilateral trade liberalization under the General Agreement on Tariffs and Trade (GATT), the WTO’s predecessor, many had high aspirations for this “Millennium Round. ” However, the Seattle meetings failed in the face of vigorous demonstrations by labor and environmental groups. In addition, there has been a marked lack of enthusiasm for this new round in the United States. The purpose of this paper is to provide a quantitative assessment

International migration can generate substantial welfare gains for migrants, their countries of origin, and the countries to which they migrate. The main focus of this report is on gains from the remittances that migrants send home (discussed in chapters 4–6); chapters 2 and 3 address the economic

nostic technique that relies on radio-frequency-induced nuclear resonance to chart physicochemical differences between tissues, rather than using ionizing radiation. This technique is the subject of a recent case study on medical technology by the Office of Technology Assess-ment (1). As with the previous reports in this series, which has covered such diverse technologies as computed tomographic (CT) scanning, screening for colon cancer, bone marrow transplantation, upper gastrointestinal en-doscopy, psychotherapy, cimetidine and peptic ulcer dis-ease, and treatment for alcoholism, this report provides a state-of-the-art analysis, including a cost-effectiveness study and a review of the current and future policy impli-cations of MRI. Magnetic resonance imaging, formerly referred to as

the underlying time-varying channel model and how well it can be tracked at the receiver, as well as at the transmitter. More realistic assumptions can dramatically impact the potential capacity gains of MIMO techniques. For time-varying MIMO channels there are multiple Shannon theoretic capacity definitions and
