More than five billion metric tons of agricultural residues are produced annually worldwide. Despite having multiple uses and significant potential to augment crop and livestock production, a large share of crop residues is burned, especially in Asian countries. This unsustainable practice causes tremendous air pollution and health hazards while restricting soil nutrient recycling. In this review,

This review evaluates three micro and three macro estimation approaches to determine whether unrealistic differences exist in estimating the size of nonobserved/shadow economies. While some macro-MIMIC estimates are higher than estimates using the statistical discrepancy approach, when adjusting for double-counting, MIMIC approaches provide similar results. Macro approaches usually cover not only typical

Agroecology is often considered as the ultimate and most comprehensive solution to the many challenges of the agricultural and food system, also referred to as the agri-food system. This review investigates to what extent agroecology can become the mainstream model for transforming agriculture toward more sustainable and resilient agri-food systems within the given economic and political context. We

Having experienced low prices for about a decade, the European Union Emissions Trading System has been supplemented with the market stability reserve (MSR) that adjusts the supply of allowances to market outcomes. We critically review the literature assessing the performance of the MSR against several policy objectives. In doing so, we cover both conceptual aspects and quantitative assessments. We

Identifying mechanisms of real-life human decision-making is central to inform effective, human-centric public policy. Here, we report larger trends and synthesize preliminary lessons from behavioral economic and neuro-economic investigations focusing on environmental values. We review the currently available evidence at different levels of granularity, from insights into how individuals value natural

Understanding the potential effect of environmental regulation on employment is of broad interest to key stakeholders. Concerns encompass both short- and longer-term effects on workers within the regulated sector, affected communities that already suffer from a lack of employment opportunities, and net employment in the overall economy. We begin our review by presenting a neoclassical microeconomic

Nutrient pollution from agricultural sources, coming primarily from fertilization of row crops and manure from livestock operations, affects ecological health in the United States through water and air pollution. We summarize data trends on commercial fertilizer use, manure, cropland, and concentrations of nitrogen and phosphorus in waterways. We present data indicating that fertilizer applications

We take stock of the major changes in methodology for studying the impacts of international agricultural research, focusing on the period 2006–2020. Impact assessment of agricultural research has a long and recognized tradition. Until the mid-2000s, such assessments were dominated by a model of demand for and supply of agricultural products in partial equilibrium. The basic ideas for this approach

This article develops a conceptual framework on pathways through which noncontributory social protection can support resilient and inclusive agricultural growth in rural Africa. It draws insights from a review of rigorous empirical evidence on the impacts of cash transfers and multifaceted cash plus programs on a range of relevant productive outcomes, including accumulation of productive assets, inputs

This article reviews the literature on the financial sector impacts of natural disasters and physical climate change risks, covering banking, insurance, stock markets, bond markets, and international financial flows. Most studies have applied statistical approaches to historical data from developed countries to identify these impacts, while some have also used theoretical and computational modeling

Little progress has been made in reducing deaths from chronic noncommunicable diseases associated with being overweight or obese worldwide, prompting the World Health Organization and others to recommend the implementation of taxes on sugar-sweetened beverages (SSBs). In response, SSB taxes have been widely implemented over the last decade, and a burgeoning literature aims at understanding their effects

In 2015, the United Nations and the G20 put food loss and food waste on the global agenda. While progress has been made since then, the scale of the problem persists because food loss and food waste are measured together, not separately. The paucity of data also poses a challenge. This article reviews the measurements, causes, and determinants of food loss as well as the interventions to reduce it

Traditionally, competition law and practice serve to preserve competition, with a focus on the maximization of consumer welfare. This has been criticized as conflicting with society's overarching goal of achieving greater (environmental) sustainability. Consequently, various jurisdictions have recently reformed their laws and guidance allowing them to account for sustainability benefits in the assessment

This article reviews recent economic studies on the causal effects of temperature on labor productivity. The negative effects of extreme temperatures are widespread, and the magnitudes of the impact differ across social and economic factors. In addition to physical outputs, extreme temperatures also impair mental productivity, including cognition and learning. In utero exposure to extreme temperatures

This article provides an overview of the recent economics literature analyzing the effect of air pollution on health outcomes. We review the common approaches to measuring and modeling air pollution exposures and the epidemiological and biological literature on health outcomes that undergird federal air regulations in the United States. The article contrasts the methods used in the epidemiology literature

The Annual Review of Resource Economics presents Professor Sir Partha Dasgupta in conversation with economist Dr. David Zilberman. In the conversation, we follow Sir Partha's life from his childhood in Bangladesh, where his father was a distinguished economist, to his childhood and undergraduate studies in India, his graduate studies in England, and his fascinating academic career, mostly in Cambridge

We first discuss the genesis and development of the Food Security Module in the United States. We then present a conceptual model of food insecurity, drawing on consumer choice theory. The model shows how food insecurity exhibits a quality–quantity trade-off and has linkages to policy levers. Next, we present new stylized facts pertaining to food consumption for those who report food insecurity versus

Climate change undeniably impacts agriculture and natural resources, enterprises and markets. For informed decision making, there is a need for information on climate change adaptation possibilities and mitigation alternatives. Mathematical programming has been used to address the economic aspects of such questions and allows analysis as climate change moves the environment into previously unobserved

Based on an extensive literature review and publicly available data, this article provides insights into the differences in prevalence, sociodemographics, contributing factors, socioeconomic consequences, health effects, and public policies related to obesity between developed and developing countries. Most importantly, it explores the relationship between obesity and life expectancy and identifies

An evolving literature evaluates the inferential and behavioral implications of measurement error (ME) in agricultural data. We synthesize findings on the nature and sources of ME and potential remedies. We provide practical guidance for choosing among alternative approaches for detecting, obviating, or correcting for alternative sources of ME, as these have different behavioral and inferential implications

Restoration of degraded ecosystems is essential for having a stable climate, reducing weather extremes and disease burden, producing enough food to feed growing populations, and generally keeping the world livable. However, we are currently rapidly degrading ecosystems worldwide, thus destroying the very basis of life. There is a major gap between what investments are needed to restore degraded ecosystems

Food fraud represents a serious threat to the integrity of the global agri-food marketing system and has received considerable attention by policy makers, academics, and the public at large. This review presents the conditions that enable fraudulent activity in agri-food supply chains (such as asymmetric information, imperfect certification processes, supply chain complexity, and weak monitoring and

R&D is slow magic. It takes many years before research investments begin to affect productivity, but then they can affect productivity for a long time. Many economists get this wrong. Here, we revisit the conceptual foundations for R&D lag models used to represent the temporal links between research investments and impact, review prevalent practice, and document and discuss a range of evidence on R&D

In recent decades, discrete choice experiment research applied to food choices has grown rapidly. Empirical applications include investigations of consumer preferences and demand for various food attributes, labeling programs, novel products and applications, and new food technologies. Methodological contributions include advances in the form of new theories, elicitation methods, and modeling. This

Governments across the world are coming under increasing pressure to invest heavily in projects that have maturities of decades or even centuries. Key areas of concern include climate change mitigation, environmental and biodiversity protection, nuclear decommissioning, enhancing infrastructure and coastal defenses, and long-term health care management. Whether such projects are evaluated as being

The global wildlife trade dates to antiquity. Recently, its harms to endangered species, animal welfare, and public health have become critical to address. The complexities of the wildlife trade are numerous, including the fact that much of the economic activity is illegal and unobserved. We find that wildlife products are used for sustenance, signaling status, medicine, and entertainment. There is

Our purpose is to review the economic impacts of Walmart's disruption of the food retailing industry. This review synthesizes the extant knowledge and research findings related to the economic impacts of Walmart's entry into, and subsequent domination of, food retailing in the United States and more broadly globally. The findings suggest five broad generalizations: ( a) Walmart's physical growth in

For over a century, starting with the work of Alfred Marshall (and also in resource economics), economic geography has emphasized the productivity of dense urban agglomerations. Yet little attention is paid to one key policy implication of economic geography's core mechanisms: Environmental policies can aid economic development, per se—not hurting the economy to help the environment but advancing both

A robust body of evidence shows that air pollution exposure is detrimental to health outcomes, often measured as deaths and hospitalizations. This literature has focused less on subclinical channels that nonetheless impact behavior, performance, and skills. This article reviews the economic research investigating the causal effects of pollution on nonhealth end points, including labor productivity

This review focuses on two emerging areas of agricultural product development, namely vertical farming and alternative animal products. We note that the drivers of this type of food innovation are a combination of factors that are resource based or supply chain based or reflect shifts in tastes, preferences, and food ethics. We conclude that leafy greens produced in vertical farms are now established

This article reviews the literature at the intersection of war, armed conflict, and food security, focusing on intergroup violent conflicts such as interstate conflict, civil war, insurgencies, state violence toward civilians, riots, and nonstate conflict. We briefly discuss recent trends in conflict and food security and note the channels through which conflict may impact food security in developing

Food value chains (FVCs) in developing countries are transforming rapidly, with some regions in the modern stage (led by supermarkets and large processors) and other regions in a transitional stage (led by midstream small and medium enterprises). With transformation, however, come market-performance issues related to monopoly and monopsony power, vertical bargaining, contracting, and other issues addressed

A circular economy (CE) would reduce both extraction and disposal by encouraging green design and circular business models, as well as repair, reuse, remanufacturing, and recycling. The CE started among architects and engineers, with little interest among economists. This article introduces CE concepts to economists, introduces key insights about the CE from other disciplines, and describes how economists

This article reviews the recent literature that has evaluated the effectiveness of postharvest loss (PHL)-reducing technologies for grains among smallholder farmers and small-scale traders in sub-Saharan Africa. We also develop a conceptual framework for identifying and quantifying different types of PHL that include physical quantity losses along with quality losses that are both observable (e.g.

This review examines global microalgae, seaweeds, and duckweed (MSD) production status and trends. It focuses on cultivation, recognizing the sector's existing and potential contributions and benefits, highlighting a variety of constraints and barriers over the sector's sustainable development. It also discusses lessons learned and ways forward to unlock the sector's full potential. In contrast to

One out of every three children under age 5 in developing countries lives in conditions that impede human capital development. In this study, we survey the literature on parenting training programs implemented before age 5, with the aim to increase parental investment in human capital accumulation in developing countries. Our review focuses on the implementation and effectiveness of parenting training

Wildfire is a natural phenomenon with substantial economic consequences, and its management is complex, dynamic, and rife with incentive problems. This article reviews the contribution of economics to our understanding of wildfire and highlights remaining knowledge gaps. We first summarize economic impacts to illustrate scale and trends. We then focus on wildfire management in three phases: mitigation

For many poor countries and for a majority of poor people in the world, agriculture broadly defined can be one of the most effective instruments for development. Yet using agriculture for development, while widely advocated in the development profession and effectively practiced by a number of countries, remains too often well below potential. At the invitation of the editors of the Annual Review of

Africa's rural population continues to expand rapidly, and labor productivity in agriculture and many rural-off farm activities remains low. This review uses the lens of a dual economy and the associated patterns of agricultural, rural, and structural transformation to review the evolution of Africa's rural employment and its inclusiveness. Many African countries still find themselves in an early stage

The effects of climate change on natural systems will be substantial, widespread, and likely irreversible. Warmer temperatures and changing precipitation patterns have already contributed to forest dieback and pushed some species toward extinction. Natural systems contribute to human welfare both as an input to the production of consumption goods and through the provision of nonuse values (i.e., existence

We describe the factors researchers should consider in deciding when and how to use computational general equilibrium (CGE) models for environmental policy analysis instead of partial equilibrium or engineering models. Special attention is given to modeling the social costs and benefits of regulations and the role played by labor markets. CGE models excel at quantifying interactions across different

The impacts of coronavirus disease 2019 (COVID-19) on food systems, poverty, and nutrition have been caused by generalized economic recession and disruptions in agrifood supply chains. This article reviews a growing empirical literature assessing those impacts. The review confirms that income shocks and supply disruptions have affected food security and livelihoods more where supply chains were poorly

The US national park system includes 423 sites covering more than 85 million acres of land and some of the most iconic landscapes in the country. The parks host approximately 320 million visitors a year. In this review, I survey the economics literature on national parks, focusing on four main topics: values and economic impacts of the parks, funding challenges, congestion and overcrowding, and resource

We systematically review studies evaluating the energy savings and cost-effectiveness of residential energy efficiency retrofit programs. We review 39 evaluations of 23 residential retrofit programs that were evaluated between 1984 and 2021. Our sample is restricted to program evaluations that used postretrofit household energy billing or consumption data from 140,977 retrofitted households. We report

Are natural resources a curse or a blessing? The answer may depend on how natural wealth is managed. By transforming a temporary windfall into a permanent stock in the form of a sovereign wealth fund, resource-rich economies can avoid volatility and Dutch disease effects, save for future generations, and invest locally. We review the theory behind these resource funds and explore the empirical evidence

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

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

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

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)

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

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

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

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

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

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

This article reviews recent endeavors to incorporate big data and machine learning techniques into energy and environmental economics research. We find that novel datasets, from high frequency smart meter data to satellite images and social media data, are already used by researchers. At the same time most of the analyses rely on traditional econometric techniques. Nevertheless, we find applications

The transformation of the electricity sector is a central element of the transition to a decarbonized economy. Conventional generators powered by fossil fuels have to be replaced by variable renewable energy (VRE) sources in combination with electricity storage and other options for providing temporal flexibility. We discuss the market dynamics of increasing VRE penetration and its integration in the

This survey distills recent work on the price elasticity of demand for urban and agricultural water and outlines how it can inform the design of market-based approaches to manage increasingly scarce water resources. We offer a brief description of the water sector, including the primary users, main water sources, and market failures in the allocation and use of surface water and groundwater. A review

We survey the rapidly growing economic literature on environmental catastrophes and the various approaches developed to address the hovering threats. Various theoretical descriptions of catastrophic occurrences are classified with respect to the uncertain conditions that trigger the events, the postoccurrence dynamic regime, and the form of the inflicted damage. We show that variations in each of these

Global agriculture consumes substantial resources and produces significant pollution. By shifting its production to new locations, and inducing changes in technology and input use, trade has a substantial impact on environmental sustainability of the world's food systems, but due to suboptimal environmental policy, the exact nature of these impacts is in dispute. We review the literature on agricultural
