Research and development policy in the USA: Implications for satellite communications

Research and development in fields as diverse as microelectronics and space vehicles have profoundly affected the technologies of information transmission, as well as the way in which government regulates the communications and information service industries. This article focuses on R&D policy in the USA, drawing from 1984 OTA reports. The article focuses briefly on industry and universities and at greater length on government actions and policies, indicating possible implications for communication satellites.     

Design-Based Properties of Linear Calibrated Estimators of a Finite Population Total

We extend Godambe's famous nonexistence theorem to classes of linear calibrated estimators. We also propose a new method for comparing sampling strategies in the design‐based framework without recourse to simulation.     

Privacy and Personnel Selection: Reciprocal Rights and Responsibilities

Previous models of invasion of privacy in selection have stressed applicant rights to the exclusion of applicant responsibilities, and have slighted organizational incumbents' needs to acquire accurate knowledge about prospective co-workers. To correct this imbalance, a reciprocal model, enumerating and justifying possible rights and responsibilities of applicants, organizational management, and organizational incumbents, is postulated. This normative model is contrasted with the current mistrust that characterizes many selection interactions. Propositions suggesting ways of gaining the information that organizations require, while still respecting the privacy needs of applicants, are advanced. Tentative suggestions for how human resource professionals could initiate these positive changes are suggested as well.     

Australia at the Crossroads: Radical Free Market or Progressive Liberalism? Key Issues and Conclusions

The author highlights the alternative choices open to Australian policy makers in their quest to achieve an acceptable balance between three potentially conflicting quality goals: improved efficiency (GDP per capita), full employment, and distributional equity.     

TESTING FOR MULTIPLE BUBBLES: LIMIT THEORY OF REAL‐TIME DETECTORS

This article provides the limit theory of real‐time dating algorithms for bubble detection that were suggested in Phillips, Wu, and Yu (PWY; International Economic Review 52 [2011], 201–26) and in a companion paper by the present authors (Phillips, Shi, and Yu, 2015; PSY; International Economic Review 56 [2015a], 1099–1134. Bubbles are modeled using mildly explosive bubble episodes that are embedded within longer periods where the data evolve as a stochastic trend, thereby capturing normal market behavior as well as exuberance and collapse. Both the PWY and PSY estimates rely on recursive right‐tailed unit root tests (each with a different recursive algorithm) that may be used in real time to locate the origination and collapse dates of bubbles. Under certain explicit conditions, the moving window detector of PSY is shown to be a consistent dating algorithm even in the presence of multiple bubbles. The other algorithms are consistent detectors for bubbles early in the sample and, under stronger conditions, for subsequent bubbles in some cases. These asymptotic results and accompanying simulations guide the practical implementation of the procedures. They indicate that the PSY moving window detector is more reliable than the PWY strategy, sequential application of the PWY procedure, and the CUSUM procedure.
