Protectionist Lobbying and Strategic Investment

Why are some uncompetitive industry sectors so effective in lobbying for greater protection and support? This paper attempts to explain the lobbying success of these industries in terms of the strategic role of investment in technology as a credible commitment device. By eschewing potentially profitable investment opportunities firms credibly signal to the government that the cost of a tariff reduction will be substantial. This enables the firms to lobby more effectively for policy concessions. Political considerations may therefore provide a significant incentive for firms to reject investment in newer technologies, even when these lower production costs.     

Climate Policy,Learning, and Technology Adoption in Small Countries

A significant reduction in global greenhouse gas emissions requires international cooperation in emission abatement as well as individual countries’ investment in the adoption of abatement technology. The existing literature on climate policy pays insufficient attention to small countries, which account for a substantial proportion of global emission. In this study, we investigate how climate policy and learning about climate damage affect investment in abatement technology in small countries. We consider three alternative climate policy instruments: emission standards, harmonized taxes and auctioned permits. We say that learning is feasible if an international environmental agreement (IEA) is formed after the resolution of uncertainty about climate damage. We find that, either with learning and quadratic abatement costs or without learning, harmonized taxes outperform emission standards and auctioned permits in terms of investment efficiency. Without learning, a large cost of nonparticipation (that a country incurs) in the IEA can be beneficial to the country. Whether learning improves investment efficiency depends on the size of this nonparticipation cost.     

Commitment in sequential auctioning: advance listings and threshold prices

This paper models sequential auctioning of two perfect substitutes by a strategic seller, who learns about demand from the first-auction price. The seller holds the second auction only when the remaining demand is strong enough to cover her opportunity cost. Bidding in anticipation of such a contingent future auction is characterized, including a sufficient condition for existence of an invertible (increasing symmetric pure-strategy) bidding equilibrium that facilitates the seller’s learning. A unique invertible bidding equilibrium exists for the Dutch auction format, but only when the second auction is sufficiently discounted by the bidders. In the equilibrium, high-valuation bidders shade their bids down as if the second auction were guaranteed. To counter such strategic bidding, the seller would value ex-ante commitment to hold the second auction less often. Three forms of such commitment are analyzed: commitment to list future auctions in advance, commitment to not hold the second auction unless the first price exceeds a publicly announced threshold, and commitment to a reserve-price in the second auction. I would like to thank Georgios Katsenos, Thomas Jeitschko, Miguel Villas-Boas, George Deltas, and an anonymous referee for thorough and insightful feedback.     

Efficiency Gains Under Exchange-Rate Emission Trading

In the case of emission of non-uniformly dispersed pollutants such as SO2 the negative effects depend on the location of the sources. A unit increase at one source must be compensated by either a larger or smaller reduction at another source to keep the negative effects at the same level. Emission trading between countries is possible under the Second Sulphur Protocol. Exchange rate trading and third party problems are studied within a simultaneous model facilitating impositions of various environmental constraints. Simulations based on the negotiated emission quotas are offered. Results indicate potential cost savings of 19%.     

The Clean Development Mechanism in a world carbon market

This paper discusses the role of the Clean Development Mechanism (CDM) in the market for carbon quotas and countries' commitments to reduce their carbon emission levels. We show that the CDM contributes to an efficient funding of clean technology investments in least developed countries. However, the CDM is not neutral on the global level of carbon emissions as it entices countries to raise their emission caps. The CDM may also make inappropriate the inclusion of any country that takes no emission abatement commitment. It can even make inefficient a country's decision to commit to an emission target. The implications of the presence of non‐additional projects are also analyzed.     

行业视角下减排成本估算及减排路径研究

碳达峰碳中和是中国经济发展环境治理的战略目标,减排成本与减排路径是该战略实施中两大现实问题。基于行业视角,利用投入产出方法,对行业减排成本、技术减排效应及减排路径展开研究,基本结论如下：①行业减排成本差异大,整体减排成本逐年上升。在三个代表性年份行业最高与最低减排成本相差40-60倍,减排成本绝对差值在1500-3000$/t。在2000-2010年间, 32个行业减排成本均有不同程度的上升, 全社会整体减排成本上升了56.98%。②技术进步的减排贡献较大,部分行业技术减排有限。在产出固定假设下,2000-2010年技术进步实现累计减排57.09亿t,累计技术减排率达到47.88%；但在旅游、住宿餐饮等行业技术减排率为负,技术因素导致的排放不减反增。③行业减排路径应遵循从高碳到低碳的顺序。基于减排成本与技术减排两大因素的减排路径规划显示,优先和重点减排行业主要集中在能源生产供给、加工制造、交通运输、采矿及设备制造等高能耗高排放行业；可相对延后和非重点减排行业主要为食品烟草等传统加工制造业以及金融、房地产等现代服务业。     

Strategic partitioning of emission allowances under the EU Emission Trading Scheme

The EU Emission Trading Scheme (ETS) is breaking new ground in the experience with emission trading regimes across multiple jurisdictions. Since the EU ETS covers only some industries, it implies a hybrid emission control scheme where EU member states must apply complementary domestic emissions regulation for the non-trading sectors of their economies in order to comply with their national emission reduction targets. The EU ETS thus opens up for strategic partitioning of national emissions budgets by the member states between trading and non-trading sectors. In this paper we examine the potential effects of such strategic behavior on compliance cost and emissions prices. We show that concerns on efficiency losses from strategic partitioning are misplaced. In turn, our analysis implicitly indicates significant political economy forces behind EU climate policy, as both cost-effective and strategically motivated partitioning of national emission budgets are far off from the actual break-down between trading and non-trading sectors.     

Credibility and commitment of monetary policy in open economies

We study the delegation of monetary policy to independent central bankers in a two-country world with monetary spillovers. It is shown that, under the hypotheses of imperfect commitment and private information, the equilibrium degree of commitment depends on the correlation structure of the shocks hitting the economies. When the correlation is negative (as when the variance of output depends mainly on shocks to the terms of trade) there is strategic complementarity in the degree of commitment in the two countries. When the correlation is positive (common technological or demand shocks) there is strategic substitutability. In this latter case, the degree of commitment is shown to be increasing in the correlation among shocks. Common components in the international business cycle have been shown in several studies to be relatively more relevant in developed countries. Therefore, our results may contribute to explaining why the institutional solution to the inflationary bias has been adopted in the most advanced countries.

Cleaner Technologies and the Stability of International Environmental Agreements

This paper shows that if countries are farsighted when deciding whether to defect from a coalition, then the implementation of cleaner technologies, as embodied by a reduction in the emission per output ratio, may either improve or jeopardize the chances of reaching an international environmental agreement. A small change in the emission per output ratio can result in a discrete jump in the stable size of a coalition and global welfare evaluated under the stable coalition size. In the case of three countries, the grand coalition may be destabilized by the implementation of cleaner technologies, ultimately resulting in higher global emissions and lower global welfare. In the case of more than three countries, implementing cleaner technologies may result in a discrete jump, either upward or downward, of the largest stable coalition size and welfare. We examine both, the case of a flow and that of a stock pollutant. In the latter case, we show that the higher the stock of pollution at the instant when the cleaner technology is implemented, the more likely that a grand coalition of three countries is destabilized. Measures that enhance the natural rate of decay of stock pollutants are shown to have similar effects on the size of stable coalitions to reductions in the emission per output ratio.     

The meta-technology cost ratio: An indicator for judging the cost performance of CO2 reduction

This paper constructs an innovative ratio of meta-technology cost (MTCR) by combining the meta-frontier framework and shadow price model. This ratio is not only an indicator to account for country-specific technology heterogeneity or technology heterogeneity across a group of countries to measure improvement toward the meta-frontier. This ratio also computes the absolute value difference between the real and ideal minimum marginal abatement costs for the non-market good CO₂ to achieve specific emission reduction. An equally weighted combination of technological readiness and innovation is used to classify countries into groups. The value of the MTCR via the computation of the meta marginal abatement cost (MAC^meta) and group marginal abatement cost (MAC^group-k) allows us to identify the possible improvement of marginal abatement cost (MAC) in absolute value. That is, observation of the MTCR, along with its components the MAC^meta and MAC^group-k, provides more intuitive and comprehensive information for commanding the cost performance of CO₂ reduction than the traditional meta-technology ratio alone.     

Trade-offs in sulfur emission trading in Europe

How to implement emission trading is one question in the current negotiations on a new sulfur protocol in Europe. Whereas the current protocol stipulates a 30 percent uniform reduction, national emission ceilings included in the proposed new protocol imply differentiated reductions. In addition, emission and fuel standards are proposed. This paper examines the costs and environmental impacts of emission trading. Emission trading combined with regulations is a new element in the paper. Calculations using the RAINS (Regional Acidification INformation and Simulation) model suggest that overlaying emission trading on regulations not only reduces the cost savings but has beneficial impacts as well: ecosystem protection is not changed and significant decreases in environmental benefits for countries are largely avoided. Emission trading can also be used to decrease emissions and increase ecosystem protection. If combined with existing legislation, emission trading minimizes losses in expected environmental benefits for some countries, and most countries gain. However, the initial distribution of emission ceilings has to be used so that some countries are not confronted with higher costs. Trade-offs appear to exist between the use of emission trading to achieve cost savings on the one hand, and ecosystem protection and distributional equity on the other.     

发达国家战略性新兴产业的技术政策及其启示

虽然发达国家没有"战略性新兴产业"的明确提法,但其对确立新兴产业的战略地位支持新兴产业发展方面却有着历史传统和前瞻视野,其依托新兴技术的产业也可统称为战略性新兴产业。本文对美国、英国、德国、日本等一些主要发达国家21世纪以来,特别是2008年全球金融危机后的战略性新兴产业的技术政策进行了较为系统的梳理和总结。文章认为,美英德日等国均从本国实际情况出发,并着眼于未来经济社会发展趋势和技术发展方向,对战略性新兴产业的侧重点做出了具体选择。各国均十分注重政府扶持对战略性新兴产业发展的促进作用,通过制定一系列具有很强操作性的政策措施,积极推进战略性新兴产业的关键技术开发、示范与应用,同时为促进战略性新兴产业发展营造良好的市场环境。这也对我国制定并完善促进战略性新兴产业发展的政策措施提供了重要启示。     

全球价值链嵌入、出口技术升级与制造业增加值隐含碳——来自浙江细分行业的经验证据

以外向型经济和制造业大省浙江为例,运用投入产出法测度2001—2017年浙江制造29个细分行业出口增加值隐含碳,并运用面板数据模型研究了嵌入全球价值链、出口技术升级对出口增加值隐含碳的影响。研究表明,浙江省制造业出口产品单位贸易利益的二氧化碳排放成本即出口增加值隐含碳大幅度下降。出口技术升级、贸易开放显著地降低了浙江省制造业出口增加值隐含碳,能源强度、人力资本、参与国际垂直分工等因素导致了出口增加值隐含碳的增长。交叉项检验表明,研发强度较高的行业出口技术升级会显著降低出口增加值隐含碳,外商直接投资、煤炭消耗占比、资本劳动占比较高的行业出口技术升级会导致出口增加值隐含碳的增加。     

The future of the future: Strategic foresight in Latin America

With few differences in timing, future studies in Latin America were initiated with a linear conception of reality. Orchestrated with techniques such as the Delphi, future studies were supported by mathematical principles of probability. Several countries have surpassed this stage while moving into strategic foresight. Strategic foresight analyzes the future as a multiple reality. In other words, it means thinking differently and not reading reality in a linear manner. It means accepting that there is not one future but several futures and that one question could have more than one answer.This change has demanded a shift in mentality. The presence of the disciplines in universities is of vital importance. For example, the Technological Institute of Monterrey (Mexico) and the Universidad Externado de Colombia (Bogota) offer foresight and strategy programs at the graduate level.This article describes how different individuals, groups, agencies and institutions in Latin America have emerged thanks to the support provided by the science and technology governmental agencies of each country. The author provides examples from different countries including Colombia, Brazil, Chile and Mexico. Currently, strategic foresight is slowly gaining recognition and acceptance as a compass for productive sectors and as a generator of competitiveness.However, despite the contributions of strategic foresight, Latin American countries, with the exception of some of the above-mentioned countries, have struggled to take off into the future. The role of strategic foresight can become the driving force behind this awakening, if the challenge of linking global trends with local contextualization through scenarios is accepted.

Intertemporal Emission Permits Trading Under Uncertainty and Irreversibility

This paper analyzes the effect of emission permit banking on clean technology investment and abatement under conditions where the stringency of the future cap is uncertain. We examine the problem of heterogeneous firms minimizing the cost of intertemporal emission control in the presence of stochastic future pollution standards and emission permits that are tradable across firms and through time. A firm can invest in clean capital (an improved pollution abatement technology) to reduce its abatement cost. We consider two possibilities: that investment is reversible or irreversible. Uncertainty is captured within a two period model: only the current period cap is known. We show that if banking is positive and marginal abatement costs are sufficiently convex, there will be more abatement and investment in clean technology under uncertainty than there would be under certainty and no banking. These results are at odds with the common belief that uncertainty on future environmental policy is a barrier to investment in clean capital. Moreover, under uncertainty and irreversibility, we find that there are cases where banking enables firms to invest more in clean capital.
