In the late 1980s the United States Air Force began requiring the implementation of the Avionics/ Electronics Integrity Program (AVIP). The purpose of AVIP was to utilize physics of failure analysis and test methods during development to eliminate fatigue and wearout failure mechanisms when systems are fielded. One of the key features of AVIP is the durability life test (DLT). The F-22 program was the first major weapons system to comprehensively require AVIP or the Mechanical Systems Integrity Program (MECSIP) for all equipment. The paper documents the findings and lessons learned from the F-22 program DLT for avionics and electronics. The paper discusses the driving environments of vibration and thermal cycling and test compression for those environments. Also discussed are test specifications, sample size, test setup, combined environments, failure criteria, and test instrumentation. Programmatic issues with DLT are presented. The data reduction for a large sample of tests is reported by failure type and as a function of test duration. Corrective action and corrective action verification is discussed and statistics presented. Finally, a cost-benefit analysis shows the benefit of DLT.

The birth of industrial society produced demand for the services of professionals specialized in matters related to industrial safety. Three professions—safety engineering, industrial medicine, and ergonomics—are examined. These professions are observed to either submit to single sets of demands, to integrate contradictory demands, or to experience scission. Until the late 1960s their growth appears to have been relatively peaceful and uncontroversial. From this period onward, controversy breaks out over questions related to industrial safety, and professions and government administrations grow. Increasingly, the traditional approach of safety professionals is called into question, and they adopt new orientations. These changes are mapped through the examination of data drawn principally from the United States, France, Great Britain, and to a lesser extent Brazil. The traditional standards approach competes with cost-benefit analysis and with systemic safety for influence; in addition, an emergent approach that analyzes accident causes in terms of social relations of work is detected. From Bhopal to Chernobyl, new technologies subject civilian populations to risks of catastrophic accidents, and the action of safety professionals comes under the spotlight. The analysis constructed permits new understandings of the past and the future of these professions.

Does inflation vary across the income distribution? This article reviews the growing literature on inflation inequality, describing recent advances and opportunities for further research in four areas. First, new price index theory facilitates the study of inflation inequality. Second, new data show that inflation rates decline with household income in the United States. Accurate measurement requires granular price and expenditure data because of aggregation bias. Third, new evidence quantifies the impacts of innovation and trade on inflation inequality. Contrary to common wisdom, empirical estimates show that the direction of innovation is a significant driver of inflation inequality in the United States, whereas trade has similar price effects across the income distribution. Fourth, inflation inequality and non-homotheticities have important policy implications. They transform cost-benefit analysis, optimal taxation, the effectiveness of stabilization policies, and our understanding of secular macroeconomic trends—including structural change, the decline in the labor share and interest rates, and labor market polarization. Expected final online publication date for the Annual Review of Economics, Volume 13 is August 2021. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

The article analyses the transformations of the use of eminent domain in the United States in the context of urban redevelopment programs. In the past the private property has been expropriated for public use only. Recently it is possible to forcibly transfer property, from a private subject to private developers, on the basis of a cost-benefit analysis that demonstrates that the new use is more efficient than the previous one. This profound change has been possible thanks to a progressive modification of the concept of public use. Traditionally, public use coincided with the construction of infrastructures and public utility, such as highways and railroads. Over the time, it has come to include other aims: firstly, projects of urban renewal and economic development carried forth by private developers. Essentially, it has resulted in the use of expropriation to assemble lands which are then granted to subjects who intervene in the reconfiguration of the city for private purposes. Starting from some important examples of urban development, the main phases of this process are reconstructed, also taking into account the most important decisions of the US Supreme Court that contributed to the change of doctrine, invalidating the postulate of public use as justification for expropriation.

Strategic Objective

The United States’ South Asia strategy has been based on the calculation of its overall national security priorities. In practice, when U.S. priorities are at odds with those of other regional powers, Washington tends to adopt a “no-expectations” psychological approach toward its regional partners to avoid disappointment, a technical “de-hyphenation strategy” to improve policy efficiency, and practical cost-benefit analysis to evaluate the effectiveness of its South Asia strategy. However, Washington often has to come to terms with the realities on the ground with regard to its leadership role in South Asia. For the time being, Washington has articulated its strategic objective in South Asia, that is, a regional balance of power in favor of the United States vis-a-vis its perceived competitor, China. Therefore, it has conducted conditional cooperation with Pakistan and Afghanistan on land, and committed support for India on security issues in the Indian Ocean, so as to hedge against China’s growing presence in South Asia. The enhancement of U.S.-India defense and security cooperation has fueled China’s suspicion of India’s intention to join the U.S.-led coalition against it. By the logic of balance of power, the United States will continue to regard India as a strategic counterweight to China, which is likely to increase the possibility of strategic tensions and conflicts between China and India that may finally entangle the United States.

In the Technology for a Quieter America report, motorcycles were mentioned three times, once in terms of standard test methods and twice in relation to community noise. In New York City, motorcycles placed in the top 10 bothersome noise sources identified by residents. Although there are regulated levels that manufacturers must meet, complaints about in-service motorcycle noise persist. To address this issue, a round table meeting was held in August 2012 with a broad spectrum of participants representing manufacturers, regulators, and other interested, knowledgeable engineers. In preparation of the TQA report, a workshop entitled Cost-Benefit Analysis (CBA) for Noise Control found that CBA was being applied in the area of traffic noise mitigation in regard to the use of barriers and/or quieter pavement. To address the particular CBA issues for this topic, a workshop was held in January 2014 with state and federal transportation officials and the research team responsible for the National Cooperative Highway Research Program NCHRP Report 738, Evaluating Pavement Strategies and Barriers for Noise Mitigation. The findings of these two meetings are summarized in this paper.

Economic Analyses

This chapter traces the history of cost–benefit analysis in the United States bureaucracy from the 1920s until about 1960. It is not a story of academic research, but of political pressure and administrative conflict. Cost–benefit methods were introduced to promote procedural regularity and to give public evidence of fairness in the selection of water projects. Early in the century, numbers produced by the Army Corps of Engineers were usually accepted on its authority alone, and there was correspondingly little need for standardization of methods. About 1940, however, economic numbers became objects of bitter controversy, as the Corps was challenged by such powerful interests as utility companies and railroads. The really crucial development in this story was the outbreak of intense bureaucratic conflict between the Corps and other government agencies, especially the Department of Agriculture and the Bureau of Reclamation. The agencies tried to settle their feuds by harmonizing their economic analyses. When negotiation failed as a strategy for achieving uniformity, they were compelled to try to ground their makeshift techniques in economic rationality. On this account, cost–benefit analysis had to be transformed from a collection of local bureaucratic practices into a set of rationalized economic principles.
