This paper investigates Euler equations involving security prices and household-level consumption data. It provides a useful complement to many existing studies of consumption-based asset pricing models that use a representative-agent framework, because the Euler equations under investigation hold even if markets are incomplete. It also provides a useful complement to simulation-based studies of market incompleteness. The empirical evidence indicates that the theory is rejected by the data along several dimensions. The results therefore indicate that some well-documented asset-pricing puzzles do not result from aggregation problems for the preferences under investigation.  相似文献

Complexity is a significant concern to managers and can undermine operational performance if not managed well, or if managed well could be used to strategic advantage. However, the quantification of complexity is requisite to managing and exploiting it. To date, an easily employable quantitative measure has not been introduced. This has hampered the ability of researchers to conduct large empirical studies and to gain a fuller understanding of the impacts of complexity on organizations. This has in turn impeded the ability of researchers to inform managers about how to manage complexity. This article presents one such measure, the Generalized Complexity Index (GCI), and illustrates it using publicly available data from the cruise line industry. The GCI employs the product structure diagram to create a geometric structure from which the level of the three dimensions of complexity (multiplicity, diversity, and interconnectedness) can be computed. The GCI is a function of these three dimensions. A significant advantage of the GCI is that it can be applied at multiple levels of analysis including product, portfolio, and supply chain. Implications for business diversification research and marketing strategy are introduced and future research topics are identified.  相似文献

This article traces the movement of the concept of ‘defensible space’ from New York City in the 1970s, where it was developed by the Canadian architect/planner Oscar Newman, to London in the 1980s and into design interventions in British public housing in the 1990s, through British geographer Alice Coleman, who acted as an especially powerful transfer agent. In focusing on this urban design ‘concept’ on the move we contribute to existing scholarship on policy mobility and city building in a number of ways. First, we explore an instance of the movement/mobility of a planning concept in a historical period (the recent past) largely overlooked to date. Secondly, we demonstrate that this movement was the result of a disaggregated series of expert knowledge transfers and localized translations of pre‐policy expert knowledge, generated through university‐based research work and networks. We theorize this instance of urban planning mobility by way of the interlinked insights offered by the sociology of science and policy‐mobilities literatures. As this is an instance of university research shaping public policy it also offers an opportunity to reflect upon the meaning of ‘evidence‐based policy’ and the impact agenda in contemporary higher education.  相似文献

In most developing and transition economies, far-reaching legal and regulatory reforms are essential for a successful transition to market-led economic development. One of the most important capacities of a market regulator is the ability to assess the market impacts of a regulation before it is adopted. Regulatory impact analysis (RIA) is a tool now used in most developed countries to improve understanding of the economic and social welfare impacts of a law and other forms of regulation. This article argues that institutional reforms aimed at good governance are at the core of the development process, that RIA can contribute to the quality of legal reforms and support other good governance goals, and that RIA can be implemented step-by-step by building on existing practices and investing in skills and training.  相似文献

The aim of this contribution is to present a conceptual framework with potential application across the interdisciplinary field of border studies. This framework should embrace interdisciplinarity and the contextual nature of borders. Based on the systems theory of Niklas Luhmann, it elaborates an understanding of borders as being related to a dynamic process of social bordering/bounding processes that involves spatial, social, and conceptual boundaries. By introducing the notion of ‘empirical boundary’, our framework aspires to bridge the gap between (radical) constructivist theorising and the analysis of physical realities involved in the (re)production of boundaries.  相似文献

Performance appraisals are widely used as an HR instrument. This study among 332 police officers examines the effects of performance appraisals from a behavioral ethics perspective. A mediation model relating justice perceptions of police officers’ last performance appraisal to their work affect, perceived supervisor and organizational support and, in turn, their ethical (pro-organizational proactive) and unethical (counterproductive) work behavior was tested empirically. The relationship between justice perceptions and both, ethical and unethical behavior was mediated by perceived support and work affect. Hence, a singular yearly performance appraisal was linked to both ethical and unethical behaviors at work. The finding that ethical and unethical aspects of employee behavior share several of the same organizational antecedents, namely organizational justice perceptions, has strong practical implications which are discussed as well.  相似文献
