The case of German reunification has been subject to extensive research on earnings inequality and labour market integration. However, little is known about the development of equality of opportunity (EOp) in East and West Germany after 1990. Using German micro data, we empirically analyse how circumstances beyond the sphere of individual control relate to inequality in East and West Germany. Our results show that EOp is larger in East than in West Germany. However, despite increasing income inequality, EOp remained surprisingly constant.  相似文献

Background and aims: IDegLira, a fixed ratio combination of insulin degludec and glucagon-like peptide-1 receptor agonist liraglutide, utilizes the complementary mechanisms of action of these two agents to improve glycemic control with low risk of hypoglycemia and avoidance of weight gain. The aim of the present analysis was to assess the long-term cost-effectiveness of IDegLira vs liraglutide added to basal insulin, for patients with type 2 diabetes not achieving glycemic control on basal insulin in the US setting.

Methods: Projections of lifetime costs and clinical outcomes were made using the IMS CORE Diabetes Model. Treatment effect data for patients receiving IDegLira and liraglutide added to basal insulin were modeled based on the outcomes of a published indirect comparison, as no head-to-head clinical trial data is currently available. Costs were accounted in 2015?US dollars ($) from a healthcare payer perspective.

Results: IDegLira was associated with small improvements in quality-adjusted life expectancy compared with liraglutide added to basal insulin (8.94 vs 8.91 discounted quality-adjusted life years [QALYs]). The key driver of improved clinical outcomes was the greater reduction in glycated hemoglobin associated with IDegLira. IDegLira was associated with mean costs savings of $17,687 over patient lifetimes vs liraglutide added to basal insulin, resulting from lower treatment costs and cost savings as a result of complications avoided.

Conclusions: The present long-term modeling analysis found that IDegLira was dominant vs liraglutide added to basal insulin for patients with type 2 diabetes failing to achieve glycemic control on basal insulin in the US, improving clinical outcomes and reducing direct costs.  相似文献

Successful outsourcing of military logistics depends much on cooperation and efficiency, and this article provides an in‐depth analysis of challenges this may pose using collaborative competence theory. Using an exploratory approach, this paper is based on a review of the existing literature and on the experience of the Canadian Armed Forces in a foreign theatre. Specifically, the information collected comes from on‐site observation during the UN mission in Bosnia, semistructured interviews, and archives. Our analysis shows that outsourcing military logistics activities in a foreign theatre should be seen as building and managing a “temporary network.” In order to overcome challenges in such a situation, the Armed Forces must specifically act on the adaptability of all individuals in the theatre. The approach should be based on “collaborative competence.” Copyright © 2015 ASAC. Published by John Wiley & Sons, Ltd.  相似文献

A conceptually based taxonomy of 22 distinct forms of e-shopping vehicles is proposed. A modification of the UTAUT and UTAUT2 models is introduced to explain how vehicles are interrelated in regard to consumer reliance upon them for their e-purchasing. A survey of over 1,000 millennial university students, 697 Chinese and 306 US, revealed strong support in both samples for the hypothesized six dimensional pattern underlying consumer vehicular reliance. Further, differences between Chinese and US samples lay not in the nature of the dimensions, but rather in the strength of reliance upon each dimension. Thus, the study demonstrates the utility of the concept/measure of shopper vehicular reliance, VPR (Vehicle Purchasing Reliance) for both practitioners and scientists. In cross-national comparisons, observed differences between samples in strength of reliance supported four of five hypotheses predicated on previously established national distinctions a) in trust and b) in the cultural value of individualism-collectivism.  相似文献

The relationship between market orientation (MO) and one of its most important consequences – firm performance – has received considerable attention in marketing research. Performance has been largely judged through financial or objective measures. This paper connects assimilation of MO in firms with corporate brand performance since academics have not used judgmental or market-based measures in assessing performance. We have introduced customer-based corporate brand equity to obtain a rounded idea of firm performance. This is achieved through a dyadic study, instead of self-assessment, wherein the marketing chiefs of B2B firms and their respective organisational customers are surveyed to gauge the effects of incorporating MO. We have shown that corporate brand performance is enhanced significantly in the presence of organisational innovativeness. From a practitioner’s perspective, the study details the organisational actions to be taken to assimilate MO and how those can be exploited to enhance corporate brand performance.  相似文献

The literature on trade liberalization and environment has not yet considered federal structures. In this paper, we show how the design of environmental policy in a federal system has implications for the effects of trade reform. Trade liberalization leads to a decline in pollution taxes, regardless of whether pollution taxes are set at the federal (centralized) or local (decentralized) level, and it increases social welfare. The effect under a decentralized system is smaller than if these taxes are set by the federal government, and pollution emissions therefore decline in this case. Moreover, majority bias interacts with trade liberalization if federal taxes are used.  相似文献

Objectives: Non-adherence and non-persistence to anti-hyperglycemic agents are associated with worse clinical and economic outcomes in patients with type 2 diabetes. This study evaluated treatment persistence and adherence across newer anti-hyperglycemic agents (canagliflozin, dapagliflozin, sitagliptin, saxagliptin, linagliptin, liraglutide, or exenatide).

Methods: This retrospective cohort study of Truven Health Analytics Marketscan databases included adult patients with type 2 diabetes whose first pharmacy claim for a newer anti-hyperglycemic agent was between February 1, 2014 and July 31, 2014. Treatment persistence and adherence were assessed for 12 months after the first claim (post-index). Persistence was defined as no gap 90 days between the end of one pharmacy claim and the start of the next pharmacy claim post-index. Adherence used two definitions: proportion of days covered (PDC) and medication possession ratio (MPR). Multivariable analyses of non-persistence (hazard ratios) and adherence (odds ratios) were adjusted for baseline demographics, drug cost, clinical characteristics, and other anti-hyperglycemic agents.

Results: A total of 11,961 patients met all study selection criteria. Persistence rates at 12 months were significantly greater (p?p?=?0.83; PDC?=?0.79) and canagliflozin 300?mg (MPR?=?0.92; PDC?=?0.81) were greater than for the other index anti-hyperglycemic agents (MPR?=?0.330.75; PDC?=?0.330.72). Consistent results for treatment persistence and adherence were observed in multivariable analyses that were adjusted baseline characteristics.

Conclusions: Canagliflozin was associated with better treatment persistence and treatment adherence compared with other anti-hyperglycemic agents in real-world settings.  相似文献

This research paper aims to explore the role of FDI inflows and stock market development on the promotion of renewable energy consumption. Furthermore, study investigates the effect of renewable energy consumption on CO2 emissions and economic output across a panel of Brazil, China, India, and South Africa. Study utilizes annual data from 1990 to 2012 and employs various robust panel econometric techniques. The findings confirm that both FDI inflows and stock market development play an important role in promoting renewable energy consumption. The results also reveal that renewable energy consumption helps to mitigate the growth of CO2 emissions and promotes economic development.  相似文献
