Although burning fossil fuels has environmental consequences, many countries have switched away from nuclear power in favor of fossil-fuel fired electricity production after incidents at Three Mile Island, Chernobyl, and Fukushima. This study estimates the substitution between nuclear and fossil-fuel fired electricity generation in the United States. Using an event-study framework, we leverage nuclear plant openings from 1970 to 1995 and forced nuclear plant outages from 1999 to 2014. Plant openings (nuclear outages) reduce (increase) monthly net coal-fired generation by approximately 200 GWh, implying a considerable reduction (increase) in emissions. We find that the substitution between nuclear and coal is not one-to-one, as has been assumed in prior literature. After establishing these stylized facts, we explore the potential underlying forces driving the observed substitution between coal and nuclear. 相似文献

在对制度环境、股权制衡与企业创新之间的相关性进行理论分析的基础上,利用359家深市上市企业在2008—2010年的数据,实证检验了制度环境、股权制衡对企业创新绩效的影响机理。实证结果表明:制度环境对企业创新绩效具有显著的正向影响,内部驱动力在该影响过程中发挥中介作用;股权制衡正向调节内部驱动力与企业创新绩效之间的关系;高股权制衡度能促进企业增加R&D投入,从而提高企业的创新绩效;低股权制衡度对企业R&D投入增加、创新绩效提升的影响不明显。最后针对营造良好的制度环境、建立有效的股权制衡结构等给出对策建议。 相似文献

Aim: To describe treatment pattern, complications, and direct medical costs associated with ankylosing spondylitis (AS) in Chinese urban patients.Methods: The 2013 China Health Insurance Research Association (CHIRA) urban insurance claims database was used to identify patients with AS. The identified patients were stratified by AS treatments for the comparisons of well established AS-related complications and direct medical costs. Conventional regression analyses adjusted the collected patient baseline characteristics to confirm the impact of treatments on complications and direct medical costs.Results: Of the identified 1299 patients with AS, 18.0% received non-steroidal anti-inflammatory drugs (NSAID), 11.2% received immunosuppressant, 48.2% received NSAID plus immunosuppressant, 4.6% received biologic agents, and 17.9% received medications without indication for AS. Biologic group was associated with the lowest proportion of AS-related complications (8.3%) that was confirmed by multiple logistic regression analysis (odds ratio = 0.200, p?=?.017). The biologic group was also associated with highest direct medical costs (median: RMB?=?14,539) that were confirmed by the multiple generalized linear model (coefficient = 1.644, p?.001).Conclusions: Biologics were not commonly used for AS in Chinese patients likely due to their high cost. Future studies are needed to confirm the potential long-term clinical benefits associated biologic treatment for AS. 相似文献

Aims: This study compared the risk for major bleeding (MB) and healthcare economic outcomes of patients with non-valvular atrial fibrillation (NVAF) after initiating treatment with apixaban vs rivaroxaban, dabigatran, or warfarin.Methods: NVAF patients who initiated apixaban, rivaroxaban, dabigatran, or warfarin were identified from the IMS Pharmetrics Plus database (January 1, 2013–September 30, 2015). Propensity score matching (PSM) was used to balance differences in patient characteristics between study cohorts: patients treated with apixaban vs rivaroxaban, apixaban vs dabigatran, and apixaban vs warfarin. Risk of hospitalization and healthcare costs (all-cause and MB-related) were compared between matched cohorts during the follow-up.Results: During the follow-up, risks for all-cause (hazard ratio [HR]?=?1.44, 95% confidence interval [CI]?=?1.2–1.7) and MB-related (HR?=?1.57, 95% CI?=?1.0–2.4) hospitalizations were significantly greater for patients treated with rivaroxaban vs apixaban. Adjusted total all-cause healthcare costs were significantly lower for patients treated with apixaban vs rivaroxaban ($3,950 vs $4,333 per patient per month [PPPM], p?=?.002) and MB-related medical costs were not statistically significantly different ($100 vs $233 PPPM, p?=?.096). Risk for all-cause hospitalization (HR?=?1.98, 95% CI?=?1.6–2.4) was significantly greater for patients treated with dabigatran vs apixaban, although total all-cause healthcare costs were not statistically different. Risks for all-cause (HR?=?2.22, 95% CI?=?1.9–2.5) and MB-related (HR?=?2.05, 95% CI?=?1.4–3.0) hospitalizations were significantly greater for patients treated with warfarin vs apixaban. Total all-cause healthcare costs ($3,919 vs $4,177 PPPM, p?=?.025) and MB-related medical costs ($96 vs $212 PPPM, p?=?.026) were significantly lower for patients treated with apixaban vs warfarin.Limitations: This retrospective database analysis does not establish causation.Conclusions: In the real-world setting, compared with rivaroxaban and warfarin, apixaban is associated with reduced risk of hospitalization and lower healthcare costs. Compared with dabigatran, apixaban is associated with lower risk of hospitalizations. 相似文献

Effects of the structural change on transaction costs between North America natural gas spot markets
Kannika Duangnate 《Applied economics》2017,49(7):650-663
Threshold cointegration between market pairs before and after the potential structural break associated with the shale gas revolution is examined. Pairwise transaction costs differ between the pre- and post-break periods. During the post-break period, five of seven pairwise transaction costs decrease, while the remaining two pair-wise transaction costs increase relative to the pre-break period. Alterations in natural gas flows as the result of the shale gas revolution partially explain the changes in transaction costs. 相似文献

Even though the choice of capital structure depends on the three different financial components of foreign direct investment (FDI), previous research has regarded FDI as unidimensional rather than multidimensional. This study addresses new findings in the FDI area and investigates the relevant determinants of capital structure in 30 OECD countries from 2006 to 2014 within the framework of a simultaneous equation model. Our primary findings reveal that each component has its own deterministic features driven by relevant policy variables and risks in the market. While an increase or decrease in equity capital shows the ability of the host country to attract new investments, the subsequent components are mostly used to adjust the equity capital investment exposure. 相似文献

Transaction costs are barriers for internationalisation processes. This paper investigates the practical relevance of transaction costs economics (TCE) for international supply chain management (SCM) in this era of globalisation, which is characterised by splitting up the supply chain in more and more parts. The analysis is based on data from in-depth interviews with seven manufacturing companies in the Netherlands which are actually engaged in this modern way of organising production. It is shown that the balance between transaction costs and sheer production costs (transformation costs) plays a prominent role in the strategic decisions on how and where to organise production. Especially intangible (or ‘soft’) transaction costs are important in this respect. The analysis provides insight in practical experience in the manufacturing industry in the Netherlands with transaction costs and shows how transaction costs affect decisions on transaction management, personnel policy and internationalisation of R&D. This study is to our knowledge the first to confront the theory of TCE with practice of manufacturing firms in their internationalisation decisions using in-depth interviews instead of survey data. 相似文献

Many countries have large or increasing migrant populations. We estimate the elasticity of private-sector employment to nonoil GDP for nationals and migrants using a Seemingly Unrelated Error Correction (SUREC) model. We use data from the Gulf Cooperation Council (GCC) countries, which have a particularly large share of foreign workers. Our results indicate that the employment response is statistically significantly lower for nationals, who have an estimated short-run elasticity of only 0.15 and a long-run response of 0.7, than for migrants, where the short- and long-run elasticities are 0.35 and almost unity. Lower elasticities could signal higher labour market adjustment costs. In the context of low oil prices, forecasts imply a significant jobs shortfall for nationals in the coming years. 相似文献
