The author reviews aspects of the current regulatory environment for international communications in the USA. He then contrasts that environment with a possible future. The contrast throws into relief critical shortcomings in the current situation. He concludes by suggesting legislative goals and proposing a framework for regulation. 相似文献

There is a growing concern that human health impacts from exposure to wildfire smoke are ignored in estimates of monetized damages from wildfires. Current research highlights the need for better data collection and analysis of these impacts. Using unique primary data, this paper quantifies the economic cost of health effects from the largest wildfire in Los Angeles County's modern history. A cost of illness estimate is $9.50 per exposed person per day. However, theory and empirical research consistently find that this measure largely underestimates the true economic cost of health effects from exposure to a pollutant in that it ignores the cost of defensive actions taken as well as disutility. For the first time, the defensive behavior method is applied to calculate the willingness to pay for a reduction in one wildfire smoke induced symptom day, which is estimated to be $84.42 per exposed person per day. 相似文献

Which inequalities among individuals are considered unjust? This paper reports the results of an experiment designed to study distributive choices dealing with arbitrarily unequal initial endowments. In a three-person distribution problem where subjects either know or do not know their endowments, we find impartial behavior to be a stable pattern. Subjects either compensate for initial inequalities fully or not at all in both conditions, and they do so more often when they do not know their endowment than when they know it. Moreover, the type and the size of the good to be distributed also affect the frequency of impartial behavior. 相似文献

This paper develops an optimal replacement strategy for capital intensive equipment with long delivery lead time. The strategy is based on an extended version of the real options approach to repeated replacement decisions, in which the goal is to determine the operating cost and delivery lead-time conditions upon which a replacement should be ordered.The real options approach to capital replacement problems is superior to traditional net present value (NPV) approaches, as it values of the option to adapt decisions based on current (rather than predicted) system conditions. However, previous applications of the real options approach to repeated replacement have not considered the impact of long and uncertain lead times, and have therefore focused on when to replace rather than when to order. Delivery lead times are an important consideration in an expanding mining sector in which demand for heavy mobile equipment (HME) exceeds the capacity of suppliers to provide the equipment in a timely manner.The inclusion of a lead time element results in a decision with an “option” period and an “option-less” period. Simulations are used to demonstrate the improved outcome of real options based replacement strategies compared with those derived using a traditional NPV approach, both with and without lead times. Further the performance of the order placement strategy with different boundary conditions, bounded and reflecting, is explored. No appreciable difference in performance of these strategies was identified. The optimal order placement strategy incorporating delivery lead times is displayed on a simple chart which is accessible to fleet management personnel. 相似文献

Firms and organizations in India have responded to market reforms, liberalization and globalization by improving efficiency, importing technology and by increasing in‐house R&D. This paper highlights some of the evolutionary changes that have occurred since India undertook sweeping reforms in July 1991 to open its economy to foreign participation and competition. Although some authors, such as Forbes (1999), have looked at the impact of the liberalization on India's R&D and innovation, they missed a number of dimensions that have far‐reaching implications for the process of technological capability development in India. Using the concept of technological capability, this paper makes a contribution to the discourse on the changing R&D and innovation scenario in the face of on‐going liberalization in India. It concludes with three case studies, which illustrate some of the recent changes made by industrial organisations. 相似文献

When looking at the process of regionalization the birth of the Association Of Southeast Asian Nations 《中国对外贸易(英文版)》2007,(20):56-56
When looking at the process of regionalization,the birth of the Association Of Southeast Asian Nations (ASEAN) has been a great step forward.Like the EU in Europe, ASEAN plays a similar role in Southeast Asia,an area that has seen increasing in- fluence not only in Asia but in the rest of the world. 相似文献
