We examine the dependency between the European government bond markets around the recent sovereign debt crisis. A dynamic copula approach is used to model the time-varying dependence structure of those government bond markets, evaluate the nature and strength of their dependencies over time, and gauge the transmission of the crisis shocks. Our results can be summarized as follows: i) the eurozone sovereign bond markets under consideration have a significant and positive dependence with the Greek and the EMU benchmark sovereign bond markets; ii) the dynamic-BB7 copula function best describes the dependence structure between these sovereign bond markets and provides evidence of asymmetric tail dependence; iii) the conditional probability of crisis transmission from Greece to other eurozone countries is higher than the other way around; and iv) Greece is the most vulnerable country when the eurozone entered into the sovereign debt crisis.  相似文献

The article offers a fresh, empirically grounded look at the spatialities of crisis‐triggered employment forms—a largely overlooked issue in contemporary critical geography literature. Specifically, it discusses the interconnection between investment flows from manufacturing to the built environment (capital switching) and underemployment in urban metropolitan regions to substantiate its impact on emerging spatial fixities. The article, which is based on an empirical analysis informed by a radical political economy, investigates changing fixed capital formations in Greece over an extended period prior to and during the recession, from 1995 to 2012. It traces the evolution of part‐time waged work in the capital metropolitan region of Attica (Athens) vis‐à‐vis the rest of the country's regional labour markets, focusing on the polarized 2005–2012 period and the demise of the construction industry. The article highlights that ‘disrupted’ capital switching that occurred in Greece, closely associated with recalibrated sectoral priorities and institutional interventions, resulted in the uneven sprawling of underemployment. Our findings offer insight into how the dismantling of spatial fixes within core metropolitan regions of the southern European Union (and beyond) are connected to labour surplus and successive slumps in manufacturing and construction. The article closes by calling for new theorizations of contemporary urban regional unevenness and its spatiotemporal fixities, which account for the role of changes in labour turnover time.  相似文献

Abstract

Aims: The Biventricular vs Right Ventricular Pacing in Heart Failure Patients with Atrioventricular Block (BLOCK-HF) demonstrated that biventricular (BiV) pacing resulted in better clinical and structural outcomes compared to right ventricular (RV) pacing in patients with atrioventricular (AV) block and reduced left ventricular ejection fraction (LVEF; ≤50%). This study investigated the cost-effectiveness of BiV vs RV pacing in the patient population enrolled in the BLOCK-HF trial.

Methods: All-cause mortality, New York Heart Association (NYHA) Class distribution over time, and NYHA-specific heart failure (HF)-related healthcare utilization rates were predicted using statistical models based on BLOCK-HF patient data. A proportion-in-state model calculated cost-effectiveness from the Medicare payer perspective.

Results: The predicted patient survival was 6.78?years with RV and 7.52?years with BiV pacing, a 10.9% increase over lifetime. BiV pacing resulted in 0.41 more quality-adjusted life years (QALYs) compared to RV pacing, at an additional cost of $12,537. The “base-case” incremental cost-effectiveness ratio (ICER) was $30,860/QALY gained. Within the clinical sub-groups, the highest observed ICER was $43,687 (NYHA Class I). Patients receiving combined BiV pacing and defibrillation (BiV-D) devices were projected to benefit more (0.84?years gained) than BiV pacemaker (BiV-P) recipients (0.49?years gained), compared to dual-chamber pacemakers.

Conclusions: BiV pacing in AV block patients improves survival and attenuates HF progression compared to RV pacing. ICERs were consistently below the US acceptability threshold ($50,000/QALY). From a US Medicare perspective, the additional up-front cost associated with offering BiV pacing to the BLOCK-HF patient population appears justified.  相似文献

The paper examines empirically the relationship between government revenues and expenditures in four European countries: Greece, Spain, Ireland, and Portugal. In relative terms all four may be considered as the poorest members of the European Union. Yet, they present a fairly diverse picture as far as their macroeconomic performance and fiscal position is concerned. The empirical findings from cointegration and causality tests that are reported here indicate that in the case of Greece and Ireland tax and spending decisions are taken simultaneously by the fiscal authority, the tax-and-spend hypothesis is supported in the case of Spain, while absence of any causal ordering between government expenditure and tax revenues has been established for Portugal.  相似文献

Initial Environmental Conditions and Technological Change   总被引:3,自引:0,他引:3  
This paper provides a theoretical link between the initial environmental conditions surrounding a firm's birth and first few years of operations and its process of technological change. The main argument is that initial environmental conditions influence the technological trajectories of business firms. Four mechanisms through which this influence is carried out are technological paradigm, dominant logic, organizational structure, and configuration. These mechanisms act as carriers of initial influences and constrain the future technological developments, restricting thus the possible technological trajectories a firm can follow. This paper discusses the above mechanisms and a number of propositions concerning the kind of influence different initial environmental conditions have on technological change. The paper concludes with implications for further research.  相似文献

Abstract:  This paper examines the relationship between cross-listing and corporate governance for Canadian firms, that were cross-listed on US stock exchanges during the period 1997–2003. We find that cross-listed firms have more independent boards and audit committees after the listing relative to a non-cross-listed matched sample of firms and relative to the pre-listing period. Moreover, cross-listed firms experience changes in their ownership structure after the listing. Finally, we provide evidence that the sensitivity of the relation between cross-listed firm valuation with audit committee independence and ownership structure becomes more important after the listing. The results are robust after adjusting for various firm risk characteristics. Overall, the results are consistent with the literature on the bonding role of cross-listings on US stock exchanges.  相似文献

This paper argues that multinational corporations face levels of environmental and social responsibility higher than their national counterparts. Drawing on the literatures of stakeholder salience, corporate reputation management, and evidence from the confrontation between Shell and Greenpeace over the Brent Spar, in 1995, two mechanisms – international reputation side effects, and foreign stakeholder salience – are identified and their contribution in creating an environment more restrictive, in terms of environmental and social responsibility, is elaborated on. The paper concludes with discussing the links of the work presented here with a number of ongoing debates within the filed of international business ethics, and the managerial implications of the two mechanisms identified.  相似文献

Supersaturated designs are an important class of factorial designs in which the number of factors is larger than the number of runs. These designs supply an economical method to perform and analyze industrial experiments. In this paper, we consider generalized Legendre pairs and their corresponding matrices to construct E(s 2)-optimal two-level supersaturated designs suitable for screening experiments. Also, we provide some general theorems which supply several infinite families of E(s 2)-optimal two-level supersaturated designs of various sizes.   相似文献
