AbstractThe Mekong Delta has been identified by the International Panel on Climate Change as one of the three most vulnerable areas in the world as sea levels rise due to climate change. The Vietnam Government has implemented a range of policies to assist migration in order to address these environmental problems. While much research has focused on the environmental causes of, and responses to, climate change there has been less research on the impact of environmentally motivated responses to climate change on labour force and human capital factors. This paper examines the experience of the Vietnam Government in encouraging internal migration from vulnerable agricultural areas to urban industrial cities, to explore the human capital effects of these environmentally motivated response to climate change. The paper first presents the environmental argument for migration in response to climate change, together with examples of what the Vietnam Government has done to encourage migration from the rural (originating) areas to other rural resettlement and city (receiving) areas. It then uses data collected as part of recent study into the impact of government encouragement for internal migration to explore the labour force and human capital impacts in both the originating region and receiving areas. The findings suggest that while there are social and economic advantages there are challenges, including ensuring that job opportunities are available, migrants and appropriate skills, and that labour contracts provide for job security and healthy and safe working result in improved living conditions. To address these challenges, this paper proposes a more integrated approach that acknowledges and addresses associated human capital (skills upgrading) and business development needs and integrates these with environmentally-motivated policies. 相似文献
This paper examines the relationship between CEO incentives and strong and weak corporate social performance. Using the KLD database we find that incentives have no significant relationship with strong social performance. Salary and long-term incentives have a positive association with weak social performance. 相似文献
Telaprevir (TVR,T) and boceprevir (BOC,B) are direct-acting antivirals (DAAs) used for the treatment of chronic genotype 1 hepatitis C virus (HCV) infection. This analysis evaluated the cost-effectiveness of TVR combined with pegylated interferon (Peg-IFN) alfa-2a plus ribavirin (RBV) compared with Peg-IFN alfa-2a and RBV (PR) alone or BOC plus Peg-IFN alfa-2b and RBV in treatment-experienced patients.
Methods:
A Markov cohort model of chronic genotype 1 HCV disease progression reflected the pathway of experienced patients retreated with DAA therapy. The population was stratified by previous response to treatment (i.e., previous relapsers, partial responders, and null responders). Sustained virologic response (SVR) rates were derived from a mixed-treatment comparison that included results from separate Phase III trials of TVR and BOC. Incremental cost per life year (LY) gained and quality-adjusted-life-year (QALY) gained were computed at lifetime, adopting the NHS perspective. Costs and health outcomes were discounted at 3.5%. Uncertainty was assessed using deterministic and probabilistic sensitivity analyses. Sub-group analyses were carried out by interleukin (IL)-28B genotype.
Results:
Higher costs and improved outcomes were associated with T/PR relative to PR alone for all experienced patients (ICER of £6079). T/PR was cost-effective for each sub-group population with high SVR advantage in relapsers (ICER of £2658 vs £7593 and £20,875 for partial and null responders). T/PR remained cost-effective regardless of IL-28B sub-type. Compared to B/PR, T/PR prolonged QALYs by 0.57 and reduced lifetime costs by £13,960 for relapsers. For partial responders T/PR was less costly but less efficacious than B/PR, equating to an ICER of £128,117 per QALY gained.
Limitations:
No head-to-head trial provides direct evidence of better efficacy of T/PR vs B/PR.
Conclusion:
T/PR is cost-effective compared with PR alone in experienced patients regardless of treatment history and IL-28B genotype. Compared to B/PR, T/PR is always cost-saving but only more effective in relapsers. 相似文献
This paper investigates how corruption affects firm behavior. Using an original and unusually rich dataset on bribe payments at ports matched to firm-level data, we observe how firms adapt to different types of corruption by adjusting their transport strategies. Our results suggest that firms respond to the price effects of corruption, organizing production in a way that increases or decreases demand for the public service. 相似文献
In this paper, we present an economic analysis of CO2-enhanced oil recovery (EOR). This technique entails injection of CO2 into mature oil fields in a manner that reduces the oil's viscosity, thereby enhancing the rate of extraction. As part of this process, significant quantities of CO2 remain sequestered in the reservoir. If CO2 emissions are regulated, oil producers using EOR should therefore be able to earn revenues from sequestration as well as from oil production. We develop a theoretical framework that analyzes the dynamic co-optimization of oil extraction and CO2 sequestration, through the producer's choice of the fraction of CO2 in the injection stream at each moment. We find that the optimal fraction of CO2 is likely to decline monotonically over time, and reach zero before the optimal termination time. Numerical simulations, based on an ongoing EOR project in Wyoming, confirm this result. We also find that cumulative sequestration is less responsive to the carbon tax than to the oil price. Only at very high taxes does a tradeoff between revenues from oil output and sequestration arise. 相似文献
The concept of organizational justice is important to understanding and predicting organizational behavior. A significant development in the research literature has been the separation of distributive and procedural justice. While much of the research has focused on negative outcomes, this research attempted to verify the presence of both forms of justice in the context of positive outcomes. Subjects completed an instrument designed to measure their perceptions of distributive and procedural justice. The subjects also reported their satisfaction and sense of fairness with their salary increases, their belief that the procedures to award the increases had been followed, and their level of information and agreement regarding the salary program. These measures, along with size of salary increase and gender were examined to determine their impact on the subjects' perceived level of justice. The data support the existence of the two distinct forms of justice, but suggest that procedural justice may, in turn, branch out into two aspects. One category involves being informed, and a second appears to deal with acceptance of procedures. A series of relationships are then considered. Significant gender effects were non-existent. 相似文献
