Applied researchers interested in estimating key parameters of dynamic stochastic general equilibrium models face an array of choices regarding numerical solution and estimation methods. We focus on the likelihood evaluation of models with occasionally binding constraints. We document how solution approximation errors and likelihood misspecification, related to the treatment of measurement errors, can interact and compound each other.  相似文献

This paper addresses the issue of how sustainable supply practices are actually used as a leverage for sustainable development (SD). In order to assess the level of sustainable supply management within an organization, the authors have reviewed the literature extensively and then developed a five‐step maturity model around five management dimensions. A qualitative exploratory approach based on two detailed case studies of organizations whose reputation for SD is recognized internationally has been used. This methodology allowed us to show (1) how sustainable supply practices could be used as a leverage for an organization's sustainable development approach and (2) that sustainable supply practices still have quite a distance to go with regards to the maturity model for sustainable supply, even in organizations that are often mentioned as leaders in the SD area. In these organizations, managers still emphasize environmental considerations, while neglecting practices that would make it possible to reach the three SD objectives simultaneously.

The objective of this study is to provide a direct estimate of the degree of persistence of measures of nominal and real house prices for the US economy, covering the longest possible annual sample of data, namely 1830–2013. The estimation of the degree of persistence accommodates for non-linear (deterministic) trends using Chebyshev polynomials in time. In general, the results show a high degree of persistence in the series along with a component of non-linear behaviour. In general, if we assume uncorrelated errors, non-linearities are observed in both nominal and real prices, but this hypothesis is rejected in favour of linear models for the log-transformation of the data. However, if autocorrelated errors are permitted, non-linearities are observed in all cases, and mean reversion is found in the case of logged prices, though given the wide confidence intervals, the unit root null hypothesis cannot be rejected in these cases.  相似文献

How has wellbeing evolved over time and across regions? How does the West compare to the Rest? What explains their differences? These questions are addressed using a historical index of human development. A sustained improvement in world wellbeing has taken place since 1870. The absolute gap between OECD and the Rest widened over time, but an incomplete catching up—largely explained by education—occurred between 1913 and 1970. As the health transition was achieved in the Rest, the contribution of life expectancy to human development improvement declined and the Rest fell behind in terms of longevity. Meanwhile, in the OECD, as longevity increased, healthy years expanded. A large variance in human development is noticeable in the Rest since 1970, with East Asia, Latin America, and North Africa catching up to the OECD, and Central and Eastern Europe and Sub‐Saharan Africa falling behind.  相似文献

The development of a fast and reliable Internet, new technologies online payment systems, and changes in work structure that enable and demand flexible working patterns have driven a move to a new form of Internet‐enabled labour exchange called crowdsourcing. Evidence from an in‐depth qualitative study is presented, focusing on selected users' interactions and experiences of working on two UK‐based crowdsourcing platforms. The paper shows that workers engaged in this form of labour exchange need to deploy existing employability skills and networks to effectively meet the challenges, and take advantage of the opportunities, that crowdsourcing presents. Individual factors and circumstances emerge as paramount for workers' continued engagement in this form of employment. Using selected components from an employability framework, the findings suggest that crowdsourcing can offer new pathways to practising skills and enhancing employability for some workers.  相似文献

This article draws on Margaret Radin's theorization of ‘contested commodities' to explore the process whereby informal housing becomes formalized while also being shaped by legal regulation. In seeking to move once‐informal housing into the domain of official legality, cities can seldom rely on a simple legal framework of private‐law principles of property and contract. Instead, they face complex trade‐offs between providing basic needs and affordability and meeting public‐law norms around living standards, traditional neighbourhood feel and the environment. This article highlights these issues through an examination of the uneven process of legal formalization of basement apartments in Vancouver, Canada. We chose a lengthy period—from 1928 to 2009—to explore how basement apartments became a vital source of housing often at odds with city planning that has long favoured a low‐density residential built form. We suggest that Radin's theoretical account makes it possible to link legalization and official market construction with two questions: whether to permit commodification and how to permit commodification. Real‐world commodification processes—including legal sanction—reflect hybridization, pragmatic decision making and regulatory compromise. The resolution of questions concerning how to legalize commodification are also intertwined with processes of market expansion.  相似文献

The present article offers a concise theoretical conceptualization and operational analysis of the contribution of innovation to regional development. The latter concepts are closely related to geographical proximity, knowledge diffusion and filters and clustering. Institutional innovation profiles and regional patterns of innovation are two mutually linked, novel conceptual elements in this article. Next to a theoretical framing, the article employs the regional innovation systems concept as a vehicle to analyse institutional innovation profiles. Our case study addresses three Portuguese regions and their institutions, included in a web-based inventory of innovation agencies which offered the foundation for an extensive database. This data-set was analysed by means of a recently developed principal coordinates analysis followed by a Logistic Biplot approach (leading to a Voronoi mapping) to design a systemic typology of innovation structures where each institution is individually represented. There appears to be a significant difference in the regional innovation patterns resulting from the diverse institutional innovation profiles concerned. These profiles appear to be region specific. Our conclusion highlights the main advantages in the use of the method used for policy-makers and business companies.  相似文献

Sales control systems are instruments used by firms to improve performance and other organizational outcomes. To understand their antecedents and consequences, this paper conducts a meta‐analysis based on 104 studies. The results showed significant relationships between behaviour‐ and outcome‐based control systems and the complexity of the products, bonuses, financial performance, sales innovation, organizational support and satisfaction with supervisors. The outcomes revealed that behaviour‐based control systems were the most effective mechanism in turbulent markets and for determining financial performance. However, outcome‐based control systems were the most efficient instrument for complex products.  相似文献

Business schools are the “nurseries” of the corporate world. This article offers an empirical analysis of the business student ethos on the basis of research conducted at three Dutch universities. A theoretical framework in the tradition of virtue ethics and dubbed “moral ethology” is used to identify the values business schools convey to their students. The central research question is: What types of ethos do Dutch business students have? Forty-three undergraduate students participated in Q-methodological research, a mixed qualitative–quantitative small-sample method. Five different types of ethos were generated: Do-Good Managers, Market Managers, Searching Managers, Balancing Managers, and Radical Market Managers. Some general characteristics that apply to all the types of ethos were identified, such as the search for efficiency. It is argued that business schools should pay much more attention to the values that are endorsed in both life and business and should help students to address situations in which values are neglected.  相似文献
