较之"线性定价","非线性定价"在社会福利方面的优势被现有理论反复证明。在肯定"非线性定价"方式能够改进社会总福利的同时,指出并不是每一个市场主体的福利水平都能够通过"非线性定价"方式得到改进。通过建立模型、计算和比较分析,提出了在上述两种情况下,"非线性定价"可能会对特定的市场主体产生"福利剥夺",从而出现福利再分配效应。 相似文献

销售电价改革呼声日涨,销售电价由市场决定是改革的最终目标,考虑到我国实际情况及电力行业作为国民经济的基础,实现销售电价由政府管制状态向市场化的平稳过渡是改革成功的关键。本文从电价制定者的角度出发,考虑基础产业价格的敏感性与社会福利最大化,设计出基于非线性规划理论和最优控制理论的销售电价静、动态调整模型,使用Kuhn—Tucker定理和Hamilton方法求解模型并给出仿真算例。结果表明:本文设计的静、动态调整模型均能实现电价有效平稳过渡,而基于最优控制的动态调整策略更能有效利用电力资源和充分增加社会整体福利。 相似文献

中国省际经济增长的空间关联网络结构--基于非线性Granger因果检验方法的再考察 总被引:1,自引:0,他引:1
文章基于经济增长空间传导的非线性趋势,利用最新发展起来的非线性Granger因果检验技术,对中国省际经济增长的空间溢出关系进行了识别,并在社会网络分析框架下揭示了其网络结构特征。研究发现:(1)线性 Granger因果检验方法严重低估了中国省际经济增长的空间关联性,而采用非线性Granger因果检验方法不仅可以揭示出更多的空间关联关系,而且能够识别出更多可能的空间溢出渠道,这为提升中国经济增长的空间协同效应提供了更多的实证支持。(2)中国省际经济增长从整体上呈现出更紧密的、更稳定的网络结构形态,在中国省际经济增长的最大可能性网络(ML-Network)中没有任何一个省份能够“孤立”于整体网络。“不谋全局者,不能谋一域”,必须从全局的、整体的视角重新审视中国区域经济的协调发展,探寻并创造出更多的空间溢出渠道,发挥经济增长不同板块的不同功能,实现区域经济空间的协同发展。 相似文献

Humanity faces ongoing and contemporaneous grand challenges. Occasionally, abrupt shocks escalate a grand challenge’s salience over others. Prior research has advocated forming partnerships to address grand challenges via responsible innovation. Yet, it remains unclear how temporal changes in the salience of a grand challenge impact innovation performances of partnerships. We address this research gap by bridging the literature on issue salience, responsible innovation and interorganizational relationships. We argue that shocks either aid or harm the performance of partnerships for responsible innovation depending on whether their domains are directly or indirectly affected. The Ebola outbreak in 2014 sets the empirical context to test our theory. We find that while the innovation performance of Ebola partnerships formed after the outbreak rose eleven-fold, the performance of partnerships treating Influenza fell by 84.9 per cent. Our theory and findings have immediate implications for today’s COVID-19 outbreak, cautioning against salience shifts among concurrent grand challenges. 相似文献

This paper investigates nonlinearities in the dynamics of real exchange rates. We use Monte Carlo simulations to establish the size properties of the Teräsvirta-Anderson test, when the dynamics of the real exchange rate is influenced by an exogenous process. In addition, we show that a modified nonlinearity test, which includes additional right-hand-side variables, performs much better than the original in both Monte Carlo exercises and in the actual data on 1431 bilateral real exchange rate series. Finally, we investigate the dynamics of the real exchange rate for both developed and developing countries using the modified test for the recent floating period. In general, the results find a greater incidence of nonlinear dynamics for developing country real exchange rates. 相似文献

The service sector in India has emerged as the ‘new engine of growth’ with an increasing share in output and exports. In this paper we analyse the effect of real exchange rate movements on service exports of India, incorporating goods exports, financial development, FDI inflows, world demand and the role of globalization as drivers. We find that while traditional service exports are negatively and significantly affected by the real exchange rate movements, the modern service exports are negatively but not significantly affected. By applying the asymmetric cointegration approach, the results also confirm the non-existence of any asymmetric relationship between the real exchange rate and service exports in India. Further, the results also show that the supply augmenting and demand-side factors are more dominant than the exchange rate to affect service exports from India. 相似文献

This article uses a smooth transition regression (STR) model to research the income elasticity of the health care expenditure of China’s urban residents in the 1990–2013 period. The results demonstrate that if the real income of China’s urban residents that lags a period is taken as a transition variable, urban residents’ health expenditure follows an LSTR1 nonlinear two-regime model. Here, the income elasticity of health care expenditure of China’s urban residents is 1.4919 in 1990–2002 and 1.2216 in 2003–2013. Overall, the income elasticity of health care of China’s urban residents is greater than 1, indicating that health care is a luxury. 相似文献

Building on literature in social psychology that discussed betrayal in interpersonal relationships, this article explored betrayal in buyer–seller relationships using data collected from a survey conducted among 109 buyers and 115 sellers in the United States. The results indicated that betrayal was a complex, multifarious, and dynamic phenomenon, consisting of a sequence of phases, namely causes, symptoms, forms, consequences, and therapies, with multiple issues being involved at each phase. Our study also revealed that the views of buyers differed from those of sellers in terms of how various relational characteristics contributed to the emergence of betrayal episodes, what behavior and attitudes helped to diagnose partner betrayal, in which forms the betrayal acts were manifested, how the victims of betrayal felt, and how betrayal problems could be handled in a working relationship. In fact, the various dimensions in each of the betrayal phases examined were consistently more frequently mentioned by buyers than sellers. 相似文献
