基于汇率传递的风险溢价渠道,本文将我国利率调控通胀、外汇储备对冲干预汇率纳入新凯恩斯政策模型,构建双目标双工具政策分析框架,比较泰勒规则与双目标双工具规则下通胀目标与汇率目标共存的经济机制与效应。本文模拟显示:(1)双目标双工具政策框架下通胀目标与汇率目标能够共存,此时通过影响汇率风险溢价来盯住汇率不影响通胀;而单工具政策下两目标无法共存,此时降低国内资产的收益率盯住汇率会刺激居民的消费行为引起通胀。(2)国际资本冲击下,双目标双工具政策在固定汇率的同时能保证经济稳定;而当贸易条件恶化时,选择完全浮动汇率制度最优。央行政策损失分析进一步验证了以上结论。(3)随着金融市场化改革深入,外汇储备稳定汇率的有效性将下降,冲销成本会大幅提升。资本账户开放下,双目标双工具政策仍是央行抵御外部资本冲击的首选政策;但是汇率市场化后,通胀目标制与双目标双工具政策效果基本无差异。本文结论的启示是:面对国际资本,需必要的汇率管制;但是面对贸易冲击,可适度提升汇率弹性来减少冲击对产出和通胀的影响。  相似文献

以一条由制造商和零售商组成的二级供应链为研究对象,通过测算产业互联度与双循环程度,研究对供应链合作稳定性的影响.研究发现:在国内环境中,产业互联度与内循环程度呈正比关系,产业互联度越高,内循环程度越高;内循环度程度提高,内需扩大,供应链上的企业选择合作时的整体收益要大于不合作时的收益,因此达到供应链长期稳定合作.通过从国内角度寻找出的规律应用于国际供应链中,为企业参与全球经济提供启示.  相似文献

Banking groups exploit double leverage when ‘debt is issued by the parent company and the proceeds are invested in subsidiaries as equity’. Financial authorities have frequently raised concerns about the issue of double leverage because this type of intra‐firm financing appears to allow for both the arbitrage of capital and the assumption of risk. This article focuses on the relationship between double leverage and risk‐taking within banking groups. First, we discuss this relationship based on an examination of balance sheet figures. Second, we analyze a large sample of United States Bank Holding Companies (BHCs) from 1990–2014. The results show that BHCs are more prone to risk when they increase their double leverage, namely, when the stake of the parent within subsidiaries is larger than the stand‐alone capital of the parent. This paper's primary implication for policymakers is that the regulators of complex financial entities should more efficiently address the issue of double leverage, thereby limiting the potential negative consequences that arise from corporate instability.  相似文献

A carbon tax is potentially a policy that can reduce CO2 emissions and mitigate climate risks, at lowest economy-wide costs. We develop a dynamic CGE model for Spain to assess the economic and environmental effects of a carbon tax, and test the double dividend (DD) hypothesis. We simulate the impact of three carbon taxes: €10, €20 and €30 per ton of CO2. For each tax, four ‘revenue recycling’ scenarios are examined: a reduction of taxes on capital, on labor, on value-added tax, and a scenario in which revenues are not recycled. We find a DD for taxes of €10/ton and lower, within five to seven years of implementation. We estimate an annual CO2 emissions reduction of around 10% with this tax. Under some circumstances, the DD can be achieved for a tax of €20/ton. In any case, recycling revenues to cut pre-existing taxes reduces costs of imposing carbon taxes.  相似文献

Even when the neoliberal ideology of the free market was more dominant than it now is, the state was involved in economic activities that could be undertaken by private firms. State capitalism takes increasingly diverse forms, including beyond direct, partial or even indirect ownership. This paper briefly reviews some of these forms without claiming to be exhaustive as the shape state capitalism takes differs widely across the institutionalized contexts of countries. We assess state capitalism using Polanyi’s double movement framework and argue that this framework needs adaptation to novel forms of state capitalism that include, e.g., state-owned multinationals and sovereign wealth funds.  相似文献

ABSTRACT

This article aims to overcome an impasse in current Polanyian scholarship by suggesting a new vocabulary to explain Polanyi’s ‘double movement’ and ‘countermovement’ concepts – the unconscious countermovement and the conscious Polanyian movement. It argues current literature often misinterprets these core concepts, which can lead to a misunderstanding of Polanyi’s general thesis. This paper uses the Carton (2018. On the Nature of the Countermovement: A Response to Stuart et al.’s ‘Climate Change and the Polanyian Countermovement: Carbon Markets or Degrowth?’. New Political Economy)-Stuart et al. (2019. Climate Change and the Polanyian Counter-movement: Carbon Markets or Degrowth? New Political Economy, 24 (1), 89–102) debate on the countermovement to exemplify some of the current misapplications of the countermovement as explicitly ‘anti-capitalist’ (Stuart et al. 2019. Climate Change and the Polanyian Counter-movement: Carbon Markets or Degrowth? New Political Economy, 24 (1), 89–102) movements. This paper argues that in fact all countermovements, as described in The Great Transformation, are necessarily non-ideological. I argue that dialectics and consciousness are fundamental to understanding the double movement and countermovement concepts and that highlighting the conscious/unconscious dynamic within Polanyi’s work helps avoid misreadings of key concepts and provides a clearer and more comprehensive understanding of Polanyi’s general theory.  相似文献

通过理论分析建立生态补偿区可能会对企业经营绩效产生的影响,以福建省上游上市公司为实验组,下游上市公司为对照组,选取2011-2018年上市公司数据共584个观测值进行实证检验。研究表明:福建省流域生态补偿区的建立提高了上游企业的绩效。进一步分析其主要原因可能是:财政转移支付向上游地区倾斜促进上游环保建设;企业R&D投入的加强;企业资本结构的改变。最后从政策和企业层面提出建议,以实现流域生态补偿政策的可持续性。  相似文献

Local festivals may leverage local specialties and various historical, cultural, and artistic resources throughout their respective regions to attract tourists, inducing positive economic impacts. In this study, this paper is a first attempt to analyze the relative efficiency of local festival tourism by using parametric and non-parametric approaches with the data from local festivals held in Korea from 2015 to 2018. We also deal with the efficiency determinants of each typology of festivals by employing a truncated regression with double bootstrapping. Results showed that the leading sources of inefficiency were primarily embedded in pure technology inefficiency, while the principal operational drivers posed different effects depending on the typology of festivals. These insights have important practical implications for the local festival organizing committees and operators in Korea and are helpful in developing tailored operational strategies to maximize the efficiency among different typologies of festivals.  相似文献

We present a novel approach for modelling self serving bias by way of reference dependence. Bias is modelled as a systematic individual level deviation of the endogenous reference point from the expected price of a good in a two person k-double auction. We find that bias decreases the efficiency of the model, and that efficiency is decreasing in both the level of bias and reference dependence.  相似文献
