In this paper, we use a dynamic stochastic general equilibrium model to examine the effects of an expansion in government spending in a liquidity trap. If the liquidity trap is very prolonged, the spending multiplier can be much larger than in normal circumstances, and the budgetary costs minimal. However, given this fiscal free lunch, it is unclear why policymakers would want to limit the size of fiscal expansion. Our paper addresses this question in a model environment in which the duration of the liquidity trap is determined endogenously, and depends on the size of the fiscal stimulus. We show that even if the multiplier is high for small increases in government spending, it may decrease substantially at higher spending levels; thus, it is crucial to distinguish between the marginal and average responses of output and government debt.  相似文献

We consider a situation in which shippers (customers) can purchase ocean freight services either directly from a carrier (service provider)in advance or from the spot market just before the departure of an ocean liner. The price is known in the former case, while the spot price is uncertain ex‐ante in the latter case. Consequently, some shippers are reluctant to book directly from the carrier in advance unless the carrier is willing to “partially match” the realized spot price when it is lower than the regular price. This study is an initial attempt to examine if the carrier should bear some of the “price risk” by offering a “fractional” price matching contract that can be described as follows. The shipper pays the regular freight price in advance; however, the shipper will get a refund if the realized spot price is below the regular price, where the refund is a “fraction” of the difference between the regular price and the realized spot price. By modeling the dynamics between the carrier and the shippers as a sequential game, we show that the carrier can use the fractional price matching contract to generate a higher demand from the shippers compared to no price matching contract by increasing the “fraction” in equilibrium. However, as the carrier increases the “fraction,” the carrier should increase the regular price to compensate for bearing additional risk. By selecting the fractional price matching contract optimally, we show that the carrier can afford to offer this price matching mechanism without incurring revenue loss: the optimal fractional price matching contract is “revenue neutral.”  相似文献

An extensive review of the literature reveals a lack of insight into why some employees and their families benefit from the adoption of mobile technology while others do not. The paper summarizes the authors' efforts to answer this question. The authors undertook a longitudinal case study of the adoption and use of a BlackBerry Smartphone by 25 professional knowledge workers. Four theoretical lenses were used to help with the data analysis process: boundary theory, the social constructivist view of technology, sensemaking and attribution theory. Analysis of the Time 2 data identified three groups. Segmentors (n = 4) did not use their smartphones outside work hours. Integrators (n = 8), used their smartphones to connect to both work and family anywhere, but not any time (temporally separated work and family roles). Struggling segmentors (n = 13) felt pressured by their organization to use their device 24/7 and did so. The analysis indicates that the relationship between the use of mobile technology and successful boundary management depends on the development of a strategy to manage the device prior to adoption, the ability to change one's strategy to respond to concerns at home, and self‐control.  相似文献

One of the most interesting recent developments in global agri-food systems has been the rapid emergence and elaboration of market audit systems claiming environmental qualities or sustainability. In New Zealand, as a strongly export-oriented, high-value food producer, these environmental market audit systems have emerged as an important pathway for producers to potentially move towards more sustainable production. There have, however, been only sporadic and fractured attempts to study the emerging social practice of sustainable agriculture - particularly in terms of the emergence of new audit disciplines in farming. The ARGOS project in New Zealand was established in 2003 as a longitudinal matched panel study of over 100 farms and orchards using different market audit systems (e.g., organic, integrated or GLOBALG.A.P.). This article reports on the results of social research into the social practice of sustainable agriculture in farm households within the ARGOS projects between 2003 and 2009. Results drawn from multiple social research instruments deployed over six years provide an unparalleled level of empirical data on the social practice of sustainable agriculture under audit disciplines. Using 12 criteria identified in prior literature as contributing a significant social dynamic around sustainable agriculture practices in other contexts, the analysis demonstrated that 9 of these 12 dimensions did demonstrate differences in social practices emerging between (or co-constituting) organic, integrated, or conventional audit disciplines. These differences clustered into three main areas: 1) social and learning/knowledge networks and expertise, 2) key elements of farmer subjectivity - particularly in relation to subjective positioning towards the environment and nature, and 3) the role and importance of environmental dynamics within farm management practices and systems. The findings of the project provide a strong challenge to some older framings of the social practice of sustainable agriculture: particularly those that rely on paradigm-driven evaluation of social motivations, strong determinism of sustainable practice driven by coherent farmer identity, or deploying overly categorical interpretations of what it means to be ’organic’ or ’conventional’. The complex patterning of the ARGOS data can only be understood if the social practice of organic, integrated or (even more loosely) conventional production is understood as being co-produced by four dynamics: subjectivity/identity, audit disciplines, industry cultures/structure and time. This reframing of how we might research the social practice of sustainable agriculture opens up important new opportunities for understanding the emergence and impact of new audit disciplines in agriculture.  相似文献

This paper seeks to contribute to debates within the 'new' sociology of childhood by focusing on issues of structure and agency in the research process. Drawing on a detailed qualitative study of children's paid work and employment, funded as part of the ESRC 'Children 5-16: growing into the 21st Century' initiative, the discussion examines the extent to which it is possible to design and conduct research on and for children, where children are participants in the research process. The paper suggests that despite the best intentions of researchers, the structure and organization of research inevitably reduces children to the status of at best, participants rather than partners and at worst objects of the researchers gaze. The reasons for this relate to issues of methodology rather than method in that what counts as acceptable academic knowledge is defined in relatively narrow and conservative terms by academics who are invariably adults and to children's lack of research or academic capital.  相似文献

Abstract

The authors discuss the development of a related set of institutional repositories among several liberal arts college libraries. Contrary to the usual focus on faculty publications, the primary goal of these repositories is the promotion of student work, especially undergraduate theses. Discussion of issues concerning selection of materials and archival policies is included along with practical considerations of workflows and reflections on the advantages and disadvantages of the particular software platform (Digital Commons). Marketing the repository and the subsequent addition of other materials, including e-journals, are discussed in light of ambiguity about its purposes among campus faculty and students.  相似文献

This paper attempts to take the first steps toward developing a theory of non-governmental organizations (NGO)–state relations under dictatorship. Drawing on evidence from East Asia, the author argues that dictatorships typically employ one of two strategies in attempting to govern NGOs. First, some dictatorships follow a corporatist strategy, in which business associations, development, and social welfare organizations are co-opted into the state and controlled through a variety of strategies. Second, other dictatorships pursue an exclusionary strategy in which NGOs are marginalized and replaced with state institutions. Variation in the strategy chosen may be explained by differing levels of elite competition and the type of development strategy. Single-party states tend to regulate elite conflicts better and thus often choose corporatist strategies. In personalist regimes dictators tend to fear the organizational and mobilizational potential of NGOs and thus tend to pursue exclusionary strategies. This choice, however, is conditioned by the development strategy employed, as socialist development strategies reduce the incentives to allow NGOs.  相似文献

Although interviews are used widely in the selection of suitable job applicants, recruiters may unconsciously be operating from culturally biased frameworks. In this article, the use of interviews across different cultural backgrounds and the potential for cultural bias are presented. Two case studies are used to illustrate the importance of cultural sensitivity in successful interviewing. Effective techniques, which include establishing rapport with the candidate, building a relationship, and choosing appropriate interview styles, are provided for practitioners.  相似文献
