The House and Senate of the United States Congress recently passed legislation that directs the FCC to establish a system for using auctions to allocate the use of radio spectrum for personal communications services. There is a unique and unprecedented set of issues that arise in this context, which are of interest to economists, industry analysts, regulators, and policymakers. We discuss these issues and evaluate their likely impact on the outcome of the spectrum auctions. In addition, we argue that there may be pitfalls in the auction procedure adopted by the FCC, and we discuss possible alternative procedures.  相似文献

Value at Risk (VaR) forecasts have been increasingly accepted globally by both risk managers and regulators as a tool to identify and control exposure to financial market risk. However, modern portfolios are characterized by a constantly changing composition of security holdings that reflect portfolio managers’ strategies, expected prices, and net cash flows into the portfolio. As a result of these factors, portfolio returns are time-varying mixtures of distributions which are unlikely to be well approximated by conventional methods.  相似文献

It is incorrect and misleading to speak of unionization as a ‘human right’. The only human right is ‘self-ownership’, i.e. to pursue goals with one's own abilities but with no force or fraud against others. Government cannot dispense rights, only privileges and protections to some at the expense of others. A minimal degree of coercion exercised by government is unavoidable. But labor unions are not governments. Government has granted significant privileges to unions in the private sector, but such are not appropriate for public sector unions.  相似文献

It is proved that, under certain conditions, the ‘true’ model, from a set of alternative regression specifications involving different transformations of the same dependent variable, is the formulation for which population R2 is highest. This theorem, which requires assumptions of normality, is proved through the use of Hermite polynomials. The paper contains an appendix listing the major properties of these polynomials.  相似文献

The 2007–2009 financial crisis that evolved from various factors including the housing boom, aggressive lending activity, financial innovation, and increased access to money and capital markets prompted unprecedented U.S. government intervention in the financial sector. We examine changes in banks’ balance sheet composition associated with U.S. government intervention during the crisis. We find that the initial round of quantitative easing positively impacts bank liquidity across all bank samples. Our results show a positive impact of repurchase agreement market rates on bank liquidity for small and medium banks. We conclude that banks have become more liquid in the post-crisis period, especially the larger banks (large and money center banks). We show that real estate loan portfolio exposures have reverted to pre-crisis levels for money center banks and remained flat for all other bank samples.  相似文献

Each year at budget time, the standard question asked of the materiel management group is "Why do you have so many people?" Our answer had been that we do not have enough people. With more people, we could lower total cost and manage inventories better. The inevitable standoff occurs with each side feeling that the other does not understand the need for materiel management services. In early 1993, we decided to be prepared to answer the famous question of Dr. W. Edwards Deming, "How do you know?" We wanted to show people we really did know our business and thus initiated a project to benchmark planning, purchasing, and scheduling services of other companies. This article shares not only the results of the benchmarking efforts, but also the techniques for getting started.  相似文献
