The current monetary policy debate has focused on current estimates and the future path of the natural rate of unemployment and the equilibrium interest rate. Estimates of the natural rate of unemployment should vary over time with changes in demographics and improvements in human capital. However, these changes should be gradual. This paper shows that the estimates of the natural rate of unemployment by Federal Reserve officials and private-sector economists seem to move pro-cyclically, potentially showing too much weight given to short-term fluctuations in economic variables. As with the natural rate, there are good reasons to expect the equilibrium interest rate to change over time. In fact, the level may actually be more responsive to current economic data, reflecting changes in aggregate savings and investment. Yet, we see that equilibrium interest rate estimates by both Federal Reserve officials and private-sector economists have declined quite dramatically over the past five years. A potential concern raised in this paper is that estimates of these critical economic variables for policy determination appear to be overly sensitive to high frequency economic data.  相似文献

The paper examines the influence of mobile money usage on customer continuance intention (CCI). The study conveniently sampled 507 mobile money users to test the research model using PLS-SEM. Satisfaction, trust and active usage of mobile money were found to influence CCI. Active usage of mobile money was also confirmed as a mediator in the relationship between satisfaction and trust, on customer continuance. The study thus validated a theoretical model of customer continuance intention as it relates to mobile money usage. It has also provided a new perspective on managing customer churn in an emerging market.  相似文献

Visual processing style, defined as the relative propensity to engage in visual processing rather than verbal processing, is an individual difference variable that has been frequently investigated in the consumer psychology literature. Surprisingly, numerous studies have reported no relationship between visual processing style and viewer responses to visual elements of persuasion. We argue that this accumulation of null results is due to untenable historical theoretical assumptions that underlie the construct, along with methodological problems that are inevitably brought about by those theoretical assumptions. We reconceptualize visual processing style and test an alternative empirical operationalization of it. Using both new data and a reanalysis of data published in the Journal of Consumer Research, we find the old approach yields null results, but we find the new approach yields the expected results. The new approach reinstates the utility of incorporating propensity to engage in visual processing as an individual difference variable into consumer psychology models of visual persuasion, and it reinstates a powerful individual difference variable that can help push forward the investigation of the unique aspects of visual persuasion.  相似文献

This article adapts and applies a securitisation framework to produce an analytical explanation for the heightened geopolitical status of climate change over the past decade, as demonstrated by the breakthrough Paris Agreement of 2015. Rather than speech acts invoking security, the focus of this analysis is on the socio-scientific discourse of global climate crisis that emerged in the several year period leading to the 2009 COP 15 conference in Copenhagen. Two types of experts—contributory and interactional—are identified as the essential and interdependent actors that engaged in ‘crisification’, a novel crisis-based perspective on political agenda setting, in which climate crisis served as a primary discursive device employed by prominent advocates of urgent action. Contributory experts, that is, authoritative climate scientists and their institutions, together with interactional experts—non-scientist social actors who appropriated and mediated scientific data and knowledge in framing climate change as a global crisis—constituted an extended epistemic community of climate advocates. Through an array of speech acts, this extended community effectively co-constructed a convincing climate crisis discourse that consisted of quantitative data artefacts based on CO2 concentration and global mean temperature, and qualitative invocations of existential threat to human civilisation, which contributed to the ascent of climate change on the global political agenda. In proposing crisification as a complement to securitisation, the article offers a theoretical innovation that facilitates constructivist analysis of issues framed as crises, including geopolitical problems in certain non-military sectors where crisis is a favoured label for perceived threats to core values.  相似文献

The objective of this article is to understand more fully the determinants of sports performance. To do this, we estimate a production function of sports results that explains the results of the Toulouse rugby union team's matches expressed as the gap in points between it and its opponents. To the best of our knowledge, this is the first time that a production function has been estimated in rugby union. In addition, it is one of the few production functions specified at the match level. The study confirms the relevance of some variables already identified in the literature, such as home advantage, ranking, the role of the referee, and in‐match statistics. It also shows the influence of new variables, such as weather conditions and the relative strength of fielded teams measured by comparing the teams selected on match day to the ideal teams defined at the beginning of the season.  相似文献

Urban entrepreneurialism and neoliberal urban governance are assuming new forms under finance‐dominated accumulation. We examine and contribute to theorizing the mechanisms through which urban governance is financialized, taking as a case study JESSICA, one of the European Union's initiatives to implement an ‘urban sensitive’ policy for sustainable and integrated development. Like other initiatives promoting financialization, JESSICA deploys the logic of finance to select and fund urban social initiatives and development projects on the basis of their potential return on investment (ROI). Understanding this process requires placing questions of political economy—how urban governance is shaped by the broader political‐economic context—with questions of governmentality—how stakeholders are enrolled in and come to take for granted new governance initiatives. Following the multi‐scalar institutional infrastructure is crucial to understanding how this works. Taking a relational multi‐scalar approach, we trace how changes at the supranational scale filter down to shape urban policy selection and performance in Sofia, Bulgaria, where we document how ROI calculations conflict with social welfare priorities. Contrasts between the trajectory of financialization of urban governance in the European Union and the United States demonstrate how this is geographically variegated, shaped by the broader context/conjuncture within which such financialization is embedded.  相似文献

This article examines the design and implementation of the Expanded Public Works Programme, drawing from the lessons of the Gundo Lashu programme on labour-intensive construction in the road sector. The aim of the study was to examine major barriers to the design and implementation of the programme. The article is based on the analysis of data that were gathered from the Gundo Lashu programme. The data were collected using a structured questionnaire, face-to-face interviews with the project participants as well as reviewing key secondary data from the project documents. The study found that the projects under the Gundo Lashu programme have clearly demonstrated the importance of labour-intensive approaches, especially in the road sector. However, these projects were constrained by a wide range of challenges, ranging from a lack of community participation to poor product quality and inadequate planning for sustainable financing.  相似文献
