Why did the conventional leverage indicators not pick up any meaningful signal of the mounting systemic risk before the subprime crisis? They remained almost unchanged in recent decades, whereas the banking landscape underwent a tremendous metamorphosis. Market-oriented banking is characterized by a new type of systemic risk, a risk which essentially evolves off the radar screen, i.e., off-balance sheet (OBS) (Calmès and Théoret Journal of Banking and Finance 34 (7): 1719–1728, 2010, 2011). In this article, we argue that the standard leverage indicators are not fitted to capture this kind of new banking risk. We introduce a new empirical framework which enables us to exploit the cyclical properties of elasticity leverage measures, while at the same time controlling for the noisy information they usually deliver. In a nutshell, thanks to the Kalman filter, we are able to compute optimal levels of bank leverage. This methodology delivers cyclical, forward-looking measures signalling systemic risk bubbles years before their burst. By properly accounting for all activities, including market-oriented banking, these time-varying leverage measures tend to systemically capture regulatory capital arbitrage and the OBS risk it entails.  相似文献

Based on the approach developed by Elliott et al. (2005), we found that the loss function of a sample of oil price forecasters is asymmetric in the forecast error. Our findings indicate that the loss oil price forecasters incurred when their forecasts exceeded the price of oil tended to be larger than the loss they incurred when their forecast fell short of the price of oil. Accounting for the asymmetry of the loss function does not necessarily make forecasts look rational.  相似文献

In this Paper, using the techniques in cointegration theory, we find strong support for the existence of a long-run equilibrium relationship among money demand variables in Canada. Additionally, when the conventional partial adjustment model (PAM) is compared to the two-stage error correction model (ECM), the latter approach is found to perform better, with M2+ showing better results than M2. Our results are also found to be in line with other studies from the U.K. and the U.S.A. These findings provide rationale for further in-depth studies on broader monetary aggregates to formulate sound monetary policy in Canada. [E41]  相似文献

The debate between De Long and Summers (1991, 1992) and Blomstrom, Lipsey and Zejan (1996) who reported conflicting results on the relationship between fixed capital formation and economic growth raised doubts on whether changes in a country's capital formation shares in GDP have an influence on its future growth rates. This paper addresses the issue again by examining the causal patterns between the share of fixed investment in GDP and the growth rate of per capital real GDP on an individual country basis, using time series on each of the group-of-seven countries. The empirical results suggest that the causal relationship between these variables may vary significantly across the major industrialized countries that presumably belong to the same growth group. Most importantly, no consistent evidence is found that causality is running in only one direction. Rather, causality between fixed investment and growth seems to have a country-specific nature and may run in either directions.  相似文献

The purpose of this paper is to investigate the relationship between private R&D, public innovation support transferred to the private sector, and productivity in Danish manufacturing. Two main conclusions are established. First, public innovation support has a positive and significant effect on private R&D expenditures with an estimated elasticity of 0.062. Second, the indirect effect on productivity from public innovation support is reflected in a positive point estimate which is found to be robust to different specifications of R&D capital.  相似文献

This article investigates transitions at the level of societal functions (e.g. transport, communication, housing). Societal functions are fulfilled by socio-technical systems, which consist of a cluster of aligned elements, e.g. artefacts, knowledge, user practices and markets, regulation, cultural meaning, infrastructure, maintenance networks and supply networks. To understand how transitions from one socio-technical system to another come about, the article describes a conceptual multi-level perspective. The perspective is illustrated with a historical case study: the transition from horse-drawn carriages to automobiles in the USA (1860–1930). The case study shows that technological substitution approaches to this transition are too simple, because they neglect the electric tram and bicycle, which acted as important stepping stones. The case study also corrects another mistake, namely that the gasoline car won by chance from steam and electric automobiles. It will be shown that particular niches played a crucial role in this competition, as well as the wider socio-technical context. The case study deviates on three points from the multi-level perspective. These deviations are used to conceptualize a particular transition pathway, called ‘de-alignment and re-alignment’.  相似文献

Research regarding work with ideas in industrial settings has predominantly treated ideas as rather stable ‘black boxes’. This article contributes a new understanding of idea work and seeks to expand our understanding of how a product concept is constituted and synthesised through socio-material interaction of organisational members and engagement in idea work. The article contributes a case study of the development process behind the energy-saving Alpha Pro circulator launched by the Danish pump manufacturer Grundfos. Based on an analysis of how organisational players engage in the controversial and shifting understandings of what seems to constitute a successful product, the article offers a new perspective on navigating the players’ ideas in the political processes of innovation. It suggests that navigation of technological frames can offer a new perspective to make explicit the implicated actors’ world views, including what they perceive as relevant problems and related strategies for solving them.  相似文献

This ethnographic study aims at understanding how product development of wind turbine controls unfolds as ongoing engineer-artefact reciprocity. We adopt a Deweyan constructionist and Science-Technology-Society approach to contribute to product development and sociomaterial studies by emphasising the role of reciprocity between engineers' experience and artefacts through reading and writing doings. Reading doings involve texts such as specifications, minutes, sketches and components. Writing doings create/modify the same type of texts. In one project, convergent reciprocity enabled the development. Another project's development was blocked, restarted and completed internally at the producer. Enablers included repositioning of working practices, application of various artefacts/tools, heterogeneous engineers and creation of common ground. Constraints involved lack of openness, too malleable artefacts, no common ground and radical change of the development trajectory. The engineers' learning depends on these constraints and enablers. Three types of reciprocity occur: convergent, faded away and blocked.  相似文献

The paper reports on Jacob H. Hollander's cooperation with John Maynard Keynes and Piero Sraffa in the preparation of the latter's edition of The Works and Correspondence of David Ricardo. The report is based on archive material from various sources, including the unpublished papers of Edwin Cannan, Piero Sraffa, Jacob H. Hollander, John Maynard Keynes, and Jacob Viner, and the archive of the Royal Economic Society. The archive material consulted by us shows that, put mildly, Jacob H. Hollander did not promote Sraffa's editorial project: he held back material which he had received from Frank Ricardo and did not disclose to Sraffa that he owned several important letters which he had privately purchased. Moreover, Sraffa was refused access to Ricardiana even after he had traced them down in laborious detective work to be in Hollander's possession. Hollander's unwillingness to cooperate with Sraffa considerably delayed the publication of the Ricardo edition.  相似文献
