Addressing climate change will require significant reductions in carbon emissions. Decarbonization will likely lead to increases in energy prices, which are regressive. Poorer households spend a higher percentage of income on energy and also have less access to energy efficient options in housing, transportation (including electric vehicles), and household durables. This review summarizes the state of knowledge on the energy justice implications of the clean energy transformation along four dimensions—production of energy, energy insecurity/energy poverty, access to clean energy technologies, and impacts of policy instrument choices for achieving decarbonization. Along each dimension there is evidence of greater negative impacts on lower-income households and on Black, Indigenous, and people of color (BIPOC) households, even controlling for income. But there is also evidence that these impacts can be mitigated through policy choices. Together these findings highlight that centering justice concerns in policy debates is critical for a just and clean energy transformation. Expected final online publication date for the Annual Review of Resource Economics, Volume 14 is October 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.
应对气候变化需要大幅减少碳排放。脱碳可能会导致能源价格上涨,这是一种倒退。较贫穷的家庭在能源上的支出占收入的比例较高,而且在住房、交通(包括电动汽车)和家庭耐用品方面获得节能选择的机会较少。本文从能源生产、能源不安全/能源贫困、清洁能源技术获取和政策工具选择对实现脱碳的影响四个方面总结了清洁能源转型对能源正义的影响。在每个维度上都有证据表明,即使控制了收入,对低收入家庭以及黑人、土著和有色人种(BIPOC)家庭的负面影响也更大。但也有证据表明,这些影响可以通过政策选择来减轻。综上所述,这些发现突出表明,将公正问题纳入政策辩论,对于实现公正和清洁的能源转型至关重要。《资源经济学年度评论》第14卷的最终在线出版日期预计为2022年10月。修订后的估计数请参阅http://www.annualreviews.org/page/journal/pubdates。

Innovations in agricultural index insurance have raised expectations that the private sector can overcome shortcomings associated with more traditional indemnity-based products like multiperil crop insurance and strengthen agricultural risk management at scale across developing countries. This article updates previous reviews on agricultural insurance but differs in that it goes beyond the prognosis that recent innovations can help make insurance more commercially viable. As such, it addresses two important challenges that have received limited attention. First, it distinguishes different types of farm households and recognizes that many are excluded from the insurance market, describing additional innovations that can help make insurance more accessible to these excluded groups. Second, it acknowledges that insurance for catastrophic risks is unaffordable for most farmers and summarizes new developments in disaster assistance and safety net programs that can provide broader protection against these risks. The review concludes that cost-benefit analyses of subsidized insurance programs will be crucial for guiding public spending decisions.

农业指数保险的创新提高了人们的期望,即私营部门能够克服与多灾作物保险等更传统的赔偿性产品相关的缺陷,并在发展中国家大规模加强农业风险管理。本文更新了以前对农业保险的评论,但不同之处在于它超越了预测,即最近的创新可以帮助使保险更具商业可行性。因此,它解决了两个受到有限关注的重要挑战。首先,它区分了不同类型的农户,并认识到许多农户被排除在保险市场之外,描述了有助于使这些被排除在外的群体更容易获得保险的其他创新。其次,报告承认大多数农民负担不起灾难性风险的保险,并总结了灾害援助和安全网项目的新进展,这些项目可以提供更广泛的防范这些风险的保护。报告的结论是,补贴保险项目的成本效益分析对于指导公共支出决策至关重要。《资源经济学年度评论》第14卷的最终在线出版日期预计为2022年10月。修订后的估计数请参阅http://www.annualreviews.org/page/journal/pubdates。

Movement of labor from agriculture to nonagriculture and the associated increase in farm size through structural transformation are at the core of economic development. We conduct a comprehensive review of the literature exploring the causes and consequences of the transformation. We discuss ( a) the size and determinants for the persisting wage gap between agriculture and nonagriculture, ( b) policy-induced barriers to structural changes, ( c) the role of trade costs and technical change in shaping the nature of structural transformation and comparative advantage of regions, and ( d) how the overall development of an economy affects the relationship between farm size and farm productivity and hence changes competitiveness of different scales of farms. We also identify questions for policy and research and the ways in which new sources and interoperability of data can help answer these questions.
经济发展的核心是劳动力从农业向非农业的转移,以及通过结构转型带来的农场规模的增加。我们对文献进行了全面的回顾,探讨了转型的原因和后果。我们讨论(a)农业和非农业之间持续工资差距的规模和决定因素,(b)政策导致的结构性变化障碍,(c)贸易成本和技术变革在塑造结构转型和区域比较优势的性质中的作用,以及(d)经济的整体发展如何影响农场规模和农场生产率之间的关系,从而改变不同规模农场的竞争力。我们还确定了政策和研究的问题,以及新来源和数据互操作性可以帮助回答这些问题的方式。

Accurate measures of productivity growth are an important policy tool but are difficult to obtain in South African circumstances. In this article, we review work on the measurement of farm-level productivity in South Africa since the earliest attempts at multifactor indices in the early 1990s. The focus is on total factor productivity, but single input measures such as labor and land productivity (yields) are also discussed. Measurements using time-series and cross-sectional data are discussed separately, along with measures to explain the effect of climate change. Data deficiencies are also pointed out. The article concludes that international collaboration should be maintained if important issues such as the COVID-19 impact, food security, climate change, and labor market shocks are to be successfully addressed.
对生产率增长的准确衡量是一项重要的政策工具,但在南非的情况下很难获得。在本文中,我们回顾了自20世纪90年代初最早尝试使用多因素指数以来南非农业水平生产率的测量工作。重点是全要素生产率,但也讨论了单一投入措施,如劳动和土地生产率(产量)。分别讨论了使用时间序列和截面数据的测量方法,以及解释气候变化影响的措施。同时指出了数据的不足。文章的结论是,如果要成功解决COVID-19影响、粮食安全、气候变化和劳动力市场冲击等重要问题,就必须保持国际合作。

Group incentives can and have been used to address a range of environmental and resource problems. These schemes base individual penalties and/or rewards on the performance of a group of individuals or firms who contribute to the environmental or resource problem. The economics literature on team incentives and public goods, as well as the literature specifically on environmental and natural resource management, provides insights into the design of group incentives. This article reviews the literature on group incentives in the context of environmental protection and natural resource policy. This literature suggests that group incentives can be effective and even efficient as environmental policy tools. However, the outcomes under group incentives will likely depend on a combination of the policy design and the nature of the internal group interactions. Within-group interactions are likely to be particularly important when policies involve thresholds so that coordination is needed to reach a cooperative equilibrium.
团体奖励可以而且已经用于解决一系列环境和资源问题。这些方案根据造成环境或资源问题的一组个人或公司的表现对个人进行惩罚和/或奖励。关于团队激励和公共产品的经济学文献,以及专门关于环境和自然资源管理的文献,为群体激励的设计提供了见解。本文综述了环境保护和自然资源政策背景下群体激励的相关文献。这些文献表明,群体激励作为环境政策工具是有效的,甚至是高效的。然而,群体激励下的结果可能取决于政策设计和群体内部互动性质的结合。当政策涉及到需要协调才能达到合作平衡的限度时,群体内部的相互作用可能特别重要。

Meat has become a controversial topic in public debates, as it involves multiple sustainability dimensions. Here, we review global meat consumption trends and the various sustainability dimensions involved, including economic, social, environmental, health, and animal welfare issues. Meat has much larger environmental and climate footprints than plant-based foods and can also be associated with negative health effects. Technological options can help to increase the sustainability of meat production, but changes in consumption are required as well. At least in high-income countries, where people consume a lot of meat on average, notable reductions will be important. However, vegetarian lifestyles for all would not necessarily be the best option. Especially in low-income countries, nutritious plant-based foods are not available or affordable year-round. Also, livestock production is an important source of income for many poor households. More research is needed on how to promote technological and behavioral changes while managing sustainability trade-offs.
肉类已经成为公众辩论中一个有争议的话题,因为它涉及多个可持续性维度。在这里,我们回顾了全球肉类消费趋势和涉及的各种可持续性维度,包括经济、社会、环境、健康和动物福利问题。与植物性食品相比,肉类对环境和气候的影响要大得多,还可能对健康产生负面影响。技术选择可以帮助提高肉类生产的可持续性,但也需要改变消费方式。至少在人们平均消费大量肉类的高收入国家,显著减少肉类消费量将是重要的。然而,素食的生活方式并不一定是最好的选择。特别是在低收入国家,并非全年都能获得或负担得起营养丰富的植物性食品。此外,畜牧生产是许多贫困家庭的重要收入来源。如何在管理可持续性权衡的同时促进技术和行为变化,需要进行更多的研究。

Our world is undergoing rapid planetary changes driven by human activities, often mediated by economic incentives and resource management, affecting all life on Earth. Concurrently, many infectious diseases have recently emerged or spread into new populations. Mounting evidence suggests that global change—including climate change, land-use change, urbanization, and global movement of individuals, species, and goods—may be accelerating disease emergence by reshaping ecological systems in concert with socioeconomic factors. Here, we review insights, approaches, and mechanisms by which global change drives disease emergence from a disease ecology perspective. We aim to spur more interdisciplinary collaboration with economists and identification of more effective and sustainable interventions to prevent disease emergence. While almost all infectious diseases change in response to global change, the mechanisms and directions of these effects are system specific, requiring new, integrated approaches to disease control that recognize linkages between environmental and economic sustainability and human and planetary health.
我们的世界正在经历由人类活动驱动的快速行星变化,这些变化往往受到经济激励和资源管理的调节,影响到地球上的所有生命。同时,许多传染病最近出现或传播到新的人群。越来越多的证据表明,全球变化——包括气候变化、土地利用变化、城市化以及个人、物种和商品的全球流动——可能通过重塑生态系统与社会经济因素相协调,加速疾病的发生。在这里,我们从疾病生态学的角度回顾了全球变化驱动疾病出现的见解、方法和机制。我们的目标是促进与经济学家进行更多的跨学科合作,并确定更有效和可持续的干预措施,以预防疾病的出现。虽然几乎所有传染病都因全球变化而发生变化,但这些影响的机制和方向是系统特有的,因此需要新的、综合的疾病控制方法,认识到环境和经济可持续性与人类和地球健康之间的联系。

Changing Farm Size Distributions and Agricultural Transformation in Sub-Saharan Africa 撒哈拉以南非洲不断变化的农场规模分布和农业转型

We review the literature on the distribution of farm sizes in sub-Saharan Africa, trends over time, drivers of change in farm structure, and effects on agricultural transformation and present new evidence for seven countries. While it is widely viewed that African agriculture is dominated by small-scale farms, we show that medium-scale farms of 5 to 100 hectares are a nontrivial—and rapidly expanding—force that is influencing the nature and pace of food systems transformation in Africa. The increased prevalence of medium-scale holdings is associated with farm labor productivity growth and underappreciated benefits to smallholder farmers. However, the rise of African investor farmers is also contributing to the commodification of land, escalating land prices, and restricted land access for most local people. A better understanding of these trends and linkages, which requires new data collection activities, could help resolve long-standing policy debates and support strategies that accelerate agricultural transformation.
我们回顾了撒哈拉以南非洲地区农场规模分布、长期趋势、农场结构变化的驱动因素以及对农业转型的影响等方面的文献,并为七个国家提供了新的证据。虽然人们普遍认为非洲农业以小规模农场为主,但我们表明,5至100公顷的中等规模农场是一股重要的、迅速扩大的力量,正在影响非洲粮食系统转型的性质和速度。中等规模持股的增加与农业劳动生产率的增长和小农的利益被低估有关。然而,非洲投资农民的崛起也导致了土地的商品化,土地价格的上涨,以及大多数当地人获得土地的限制。更好地了解这些趋势和联系(这需要开展新的数据收集活动)有助于解决长期存在的政策争论,并支持加速农业转型的战略。

Economics of Marine Protected Areas: Assessing the Literature for Marine Protected Area Network Expansions 海洋保护区经济学:评估海洋保护区网络扩张的文献

H. Albers, Madison Ashworth
Marine protected areas (MPAs) provide both conservation and economic benefits. Recent international conservation actors have called for a dramatic increase in the area of MPAs from almost 8% to 30% of marine area by 2030 in a policy called 30X30. Both the economics and conservation science literatures consider MPA decisions and MPA impact, although the economics literature focuses on fishery economic outcomes. This review uses an optimization framework for MPA decisions as a lens through which to evaluate the economics literature on MPAs in the context of the 30X30 expansion decisions.

海洋保护区(MPAs)提供了保护和经济效益。最近,国际环保组织呼吁,到2030年,在一项名为“30X30”的政策中,海洋保护区的面积将从占海洋面积的近8%大幅增加到30%。经济学和保护科学文献都考虑了MPA决策和MPA影响,尽管经济学文献关注的是渔业经济成果。本综述以MPA决策的优化框架为视角,在30X30扩张决策的背景下评估MPA的经济学文献。我们主张对MPA政策问题进行更多的经济分析,包括围绕选址、设计、限制和管理选择的问题;影响评价;人们的反应;低收入国家环境和执行不完全;没有元人口的空间设置;保护而不是收获。《资源经济学年度评论》第14卷的最终在线出版日期预计为2022年10月。修订后的估计数请参阅http://www.annualreviews.org/page/journal/pubdates。

In this article, I review the academic literature on the economics of plug-in electric vehicles (PEVs), with a focus on PEV policy, benefits, and equity. PEVs are one of the most promising technologies for decarbonizing the transportation sector. As such, many government policies exist to promote their adoption. Understanding the effectiveness and equity of existing policies, what the realized environmental benefits are, and how these benefits compare to costs is crucial to improving future PEV policy. This review suggests that consumer PEV subsidies are not cost-effective and are often expensive relative to estimated environmental benefits. Furthermore, higher-income households who make up a larger share of the PEV market receive both a disproportionate amount of government subsidies as well as PEV benefits. There is considerable room for policy improvement. Expected final online publication date for the Annual Review of Resource Economics, Volume 14 is October 2022.

在这篇文章中,我回顾了插电式电动汽车(PEV)经济学的学术文献,重点是PEV政策、利益和公平。pev是交通运输部门脱碳最有前途的技术之一。因此,政府出台了许多政策来促进它们的采用。了解现有政策的有效性和公平性,实现的环境效益是什么,以及这些效益与成本相比如何,对于改善未来的PEV政策至关重要。这一审查表明,消费者电动汽车补贴不具有成本效益,而且相对于估计的环境效益而言往往昂贵。此外,在电动汽车市场中占有较大份额的高收入家庭不仅获得了不成比例的政府补贴,还获得了电动汽车的福利。政策还有相当大的改进空间。《资源经济学年度评论》第14卷的最终在线出版日期预计为2022年10月。修订后的估计数请参阅http://www.annualreviews.org/page/journal/pubdates。
