I find a strong positive association between firms' implied cost of equity capital and firm-level political risk. This effect is above and beyond the firm-level cost of equity implications of economywide political risk. Firm-level political risk contributes to elevating stock illiquidity, increases dispersion of analyst forecasts and dampens analyst coverage and these attributes, in turn, have positive cost of equity capital implications. Overall, the findings of this study suggest firm-level political risk has a non-trivial effect on increasing equity market illiquidity, increasing dispersion of earnings forecasts and decreasing analyst coverage thus increasing financing costs.  相似文献

基于中国股市微观结构的流动性与执行成本分析   总被引:9,自引:0,他引:9  
运用市场微观结构理论来分析中国股市的交易制度、流动性和执行成本后发现:(1)在佣金和交易税相等的条件下,B股的知情交易者执行成本普遍大于A股,导致B股的流动性小于A股,买卖价差显著大于A股,表明投资者对B股交易要求较高的风险报酬;(2)一旦控制住执行成本中普通交易者对知情交易者所要求的风险补偿,A、B股买卖价差的区别就消失了。因此,证券管理部门应在B股市场引入做市商制度并在微观结构理论的指导下,加强交易监管系统,从而提高B股的流动性并降低其执行成本。  相似文献

This paper analyses governance structures used to organize partnerships in R&D networks using two approaches: transaction costs theory and social capital theory. We argue that these theories are complementary; this explains forms of governance through the degrees of administrative (structural and safeguard mechanism) and social factors (cohesion and openness) they embody. Data was obtained from European R&D networks created through Framework Programmes which include a great number of universities, non profit institutions and firms. Findings show the variables that characterize and explain the governance forms based on the applicability of R&D networks. This study not only provides a theoretical model for analysing governance structures of these networks, but is also useful for both improving the management of networks and for fostering collaboration at an international level.  相似文献

Objectives: This study investigated the cost per responder and number needed to treat (NNT) in type 2 diabetes mellitus (T2DM) patients for lixisenatide compared to insulin intensification regimens using composite endpoints in the UK, Italy, and Spain.

Methods: Efficacy and safety outcomes were obtained from GetGoal Duo-2, a 26-week phase 3 trial comparing lixisenatide vs insulin glulisine (IG) once daily (QD) and three times daily (TID). Response at week 26 was extrapolated to 52 weeks, assuming a maintained treatment effect, based on long-term evidence in other T2DM populations. Responders were defined using composite end-points, based on an HbA1c threshold and/or no weight gain and/or no hypoglycemia. The HbA1c threshold was varied in sensitivity analyses. Annual treatment costs were estimated in euros (1 GBP?=?1.26 EUR), including drug acquisition and resource use costs. Cost per responder was computed by dividing annual treatment costs per patient by the proportion of responders.

Results: Lixisenatide was associated with the lowest cost per responder for all composite end-points that included a weight-related component. For the main composite end-point of HbA1c ≤7.5% AND no weight gain AND no symptomatic hypoglycemia, cost per responder results were: UK: 6,867€, 8,746€, and 12,410€; Italy: 7,057€, 9,160€, and 12,844€; Spain: 8,370€, 11,365€, and 17,038€, for lixisenatide, IG QD, and TID, respectively. The NNT analysis showed that, for every 6.85 and 5.86 patients treated with lixisenatide, there was approximately one additional responder compared to IG QD and TID, respectively.

Limitations: A limitation of the clinical inputs is the lack of 52-week trial data from GetGoal Duo-2, which led to the assumption of a maintained treatment effect from week 26 to 52.

Conclusions: This analysis suggests lixisenatide is an efficient economic resource allocation in the UK, Italy, and Spain.  相似文献

Water's role in manufacturing technologies has received limited attention. A KLEM model of the sector's technology is extended to include two facets of water use: intake and recirculation. Three annual cross-sectional surveys on plant-level water use are pooled and combined with census data to estimate this extended model for the Canadian manufacturing sector over the period 1981–1991. While Canada's water allocation regulations influence private water withdrawals, statistical tests support representing water intake as a variable input. Water intake is found to be a substitute for water recirculation, energy, labour and capital. The relationship between water intake and recirculation is stronger when water intake is process-related rather than related to cooling and steam production. Technological change has been biased in the direction of increased water intake and decreased water recirculation.  相似文献

Abstract

Objective: To determine the treatment pattern and impact on healthcare costs of anxiety disorders and major depressive disorder (MDD), and influence of their concomitance and subsequence.

Methods: A retrospective cohort study was conducted using a US reimbursement claims database. Adult patients with an incident diagnosis of anxiety or MDD (index date) were included. Their sociodemographic data, diagnoses, healthcare resource use and associated costs were collected over the 6 months preceding and 12 months following index date.

Results: A total of 599,624 patients were identified and included. Patients with phobia or post-traumatic stress disorder had the highest 12-month costs ($8,442 and $8,383, respectively). Patients with social anxiety disorder had the lowest costs ($3,772); generalized anxiety disorder ($6,472) incurred costs similar to MDD ($7,170). Costs were substantially increased with emergence of anxiety during follow-up in MDD patients ($10,031) or emergence of MDD in anxiety patients ($9,387). This was not observed in patients with both anxiety and MDD at index date ($6,148).

Conclusion: This study confirms the high burden of costs of anxiety, which were within the same range as MDD. Interestingly, the emergence of anxiety or MDD in the year following a first diagnosis of MDD or anxiety, respectively, increased costs substantially. Major limitations were short follow-up and lack of absenteeism costs.  相似文献
