碳税对我国的影响及其政策响应

二氧化碳(CO2)是引起全球气候变化的最重要的温室气体(GHG)之一。温室气体的减排是当前国际社会普遍关注的热点环境问题。碳税常常被认为是成本有效的碳减排政策工具,目前已有一些国家征收碳税或能源税。文章介绍了碳税的理论基础及其在一些国家的征收实践,总结和分析了国内外一些学者关于实施碳税对温室气体减排、对经济和能源系统的影响的研究结果,并在此基础上讨论了我国对碳税制度的政策响应和对策。     

The EU ETS and corporate environmental abatement

This article studies the relationship between firm-level emissions-to-cap ratio (ETC) and environmental abatement, by using a unique and extensive data set of 10 762 installations covered by the European Union Emission Trading Scheme (EU ETS) matched to 5931 firms. We find that a shortage of emissions allowances is related to more abatement in later years while a surplus of emissions allowances results in worse subsequent environmental performance. This finding underscores the importance of reducing the global amount of allowances in the ETS system. Our results also suggest that stakeholder pressure and the creation of transparency concerning corporate environmental performance are likely to support the effectiveness of the system.     

Incentives for Investment in Advanced Pollution Abatement Technology in Emission Permit Markets with Banking

We examine the incentives that firms have to invest in cleaner abatementtechnology when the banking of permits is allowed in emission permittrading schemes. We show that under certainty permit banking can distortincentives for investment and lead to a sub-optimal amount of investmentspending. Under imperfect information, aggregate abatement costuncertainty and investment irreversibility provide arguments for allowingbanking. We generalize the model to consider these, showing that somebanking is desirable but that it need not be the case that the privatebanking solution is optimal.

Globalization, intellectual property, and economic prosperity

Innovation and the adoption of new ideas is fundamental to economic progress, and so is free trade of goods and services. Here we examine the underlying economics of the market for ideas and its implications for trade. From a positive perspective, we examine how such markets function and how international trade interact with them. From a normative perspective, we examine the pitfalls of current intellectual property regulations, and how might they be improved. We highlight recent research by ourselves and others challenging the notion that government awards of monopoly through patents and copyright are "the way" to provide appropriate incentives for innovation.

产业共性技术研发政府支持合同

建立了产业共性技术研发三阶段博弈模型,基于政府视角研究了以企业研发投入最大化为目标的共性技术支持合同的最优设计问题,并分析了合同性质。研究结果表明:足够多的政府预算是共性技术研发最优合同存在的前提,企业的最优研发投入随着政府预算的增加而增加,且其增长速度比政府支持投入的增长速度更快;企业的最优研发投入与共性技术市场化预期收益、企业及政府投入对共性技术研发成功的影响系数正相关,与双方单位投入成本系数负相关。     

企业采用新技术的时点博弈分析

技术创新可以为企业带来超额利润,具有极大的经济价值,然而新技术的不确定性和风险性又使得企业不会立即采用。本文通过构建双寡头垄断博弈模型对企业采用新技术的时点进行研究,证明企业采用新技术时存在一个最佳时点,在这个最佳时点之前,企业应采取等待策略。     

Walras and Darwin: an odd couple?

General equilibrium theory and the evolutionary branches of economics and game theory take rather opposite positions in the spectrum covered by the economic science. However, we reveal and explore analogies between Darwinian dynamics and Walrasian tatonnement processes for pure exchange economies, as well as further analogies implied by these.

Behavior and Learning in the “Dirty Faces” Game

This paper examines the Dirty Faces problem as a Bayesian game. The equilibrium in the general form of the game requires the extreme assumption of common knowledge of rationality. However, for any finite number of players, the exact number of steps of iterated rationality necessary for the equilibrium to arise depends on the number of players of a particular type, allowing the game to be used to bound the number of steps satisfied by actual players. The game differs from other games used to study iterated rationality in that all players are better off when common knowledge of rationality is satisfied. While behavior in experiments is inconsistent with the game-theoretic prediction at the group level, individual level behavior shows a greater degree of consistency with theory and with previous results on iterated rationality. Finally, there is some evidence of learning in repeated play.     

经济金融化行为的政治经济学分析--一个演化博弈框架

自2008年美国金融危机发生以来,经济金融化成为国内外学界关注的焦点。文章从政治经济学的角度指出了金融化的本质在于资本积累演变为资本脱离剩余价值的生产与交换而通过金融系统实现增殖的过程,进而通过构建一个包含异质性主体的非对称演化博弈模型,揭示了非金融主体与金融主体之间从普通经济关系到金融关系的动态演变过程及其作用机制。研究表明：(1)经济主体之间的动态关系演变表现为非金融企业主要通过金融活动获取利润,金融企业则关注中间业务和表外业务并将普通家庭纳入其体系使之成为新的利润源泉,而普通家庭则被迫接受强势经济主体的二次分利,这些关系的变化将导致一国经济的金融化乃至金融危机。(2)经济发展状态取决于金融主体与非金融主体之间的相互关系,其中,非金融主体行为起主导性作用。在既定假设下,当非金融主体仅通过其资源保护行为影响金融主体的分利技术时,既可以促使一国经济走向新的稳定状态也可促使其走向崩溃;当非金融主体通过其资源保护行为和分利技术影响金融主体的分利技术时,经济可以实现演化稳定状态。(3)经济主体的金融化行为有三个层面的影响：一是经济主体的金融化行为促进经济主体自身在短期内实现高额资本积累;二是金融主体的分利行为与非金融主体的生产行为经常呈现对立的经济关系并容易被激化;三是没有政府介入的自由市场必然导致矛盾激化而陷入危机。因此,深入理解经济金融化问题的本质及其对经济的影响机制,对当前中国的经济转型和金融改革都具有重要意义。     

An evolutionary theory of the convergence towards low inflation rates

This paper presents an evolutionary interpretation of Barro-Gordons monetary policy game. The model describes a multi-country setup where governments and private agents are boundedly rational players. The behavioral rule of players decisions leads to the imitation of the strategy giving the highest payoff. In this evolutionary monetary policy game, we show how a low inflation state is reached from an international context dominated by inflationary policies. The analysis explains the convergence towards low inflation rates observed during the past twenty years. Moreover, the low inflation state appears to be the long-run equilibrium of the game under some conditions featuring the observed macroeconomic context.JEL Classification: E5, C72, C73 Correspondence to: A. dArtigues     

基于养殖档案的畜产品供应链质量控制信号博弈分析

针对畜产品供应链质量信息不对称的特点,在提出并论证养殖档案的畜禽质量信号传递功能的基础上,通过构建信号博弈模型,分析了畜产品供应链中畜禽养殖场户与屠宰加工企业质量控制的信号博弈均衡条件及其演变过程。研究结果表明:畜禽养殖场户的虚假养殖档案伪造成本和屠宰加工企业的质量检验成本是决定信号博弈均衡状态及其演变方向的两个关键因素;降低检验成本、增加惩罚额度、加大市场监管力度、提高外部损失额度和增加虚假养殖档案伪造成本,可推进信号博弈均衡状态向有利于畜产品质量改善的方向演变。     

植入"公平博弈"的委托-代理模型——来自行为经济学的一个贡献

本文通过将Rabin(1993)提出的"公平博弈"概念植入现有委托一代理模型,获得一个考虑了代理人表现出"互惠性"非理性行为的新委托一代理模型.由该模型给出来的最优委托一代理合约可以给委托人带来比现有委托一代理最优合约更高的利润水平.研究发现,现有的Holmstrom-Milgrom模型中的最优合约不是帕累托最优的.新模型可以解释企业人性化管理和许多有特色的人性化企业文化的形成.本文是行为经济学与现有激励理论相结合研究的一种初步尝试,是运用行为经济学原理重建信息经济学基本框架的原创性工作.     

CROSS‐COUNTRY TECHNOLOGY TRANSFER AND POLITICALLY DRIVEN INTERNATIONAL AGREEMENTS FOR ENVIRONMENTAL STANDARDS

Grossman and Helpman highlighted a political framework to internalize inefficiency incurred due to unilateral trade policy implementation by sovereign countries. This paper extensively adopts their framework to explore the effects of special interest politics on governments under negotiation to forge international environmental standards to control global emission. Particular attention is given to a case in which negotiation is driven by transferring the abatement technology. Within a specific factor model of international trade, improving the abatement efficiency through technology transfer can give the most mutually beneficial outcome, achieving the lowest level of global pollution compared to other political benchmarks.     

Methane and Nitrous Oxide Emissions from Agriculture in the EU: A Spatial Assessment of Sources and Abatement Costs

Agriculture significantly contributes to emissions of greenhouse gases in the EU. By using a farm-type, supply-side oriented, linear-programming model of the European agriculture, the baseline levels of methane and nitrous oxide emissions are assessed at the regional level in the EU-15. For a range of CO₂-equivalent prices, we assess the potential abatement, as well as the resulting optimal mix of emission sources in the total abatement. Furthermore, we show that the spatial variability of the abatement achieved at a given carbon price is large, indicating that abatement cost heterogeneity is a fundamental feature in the design of a mitigation policy. The cost savings permitted by market-based instruments relative to uniform standard are shown to be large.

Environmental Liability Law and Induced Technical Change – The Role of Discounting

We analyse the incentives of environmental liability law for inducing progress to emission abatement technology. We consider three liability rules: strict liability, a negligence rule with an emission norm as the due care standard, and a double negligence rule which combines the emission standard with an abatement technology norm. In the case of distortive discounting, i.e. where the private discount rate deviates from the social one, we show, how the level of distortion influences the ranking of liability rules, according to the criterion of generated social cost.
