Abstract
The authors estimate the impact of global merchandise trade distortions and services regulations on agricultural value added in various countries. Using the latest versions of the Global Trade Analysis Project (GTAP) database and the GTAP-AGR model of the global economy, their results suggest real net farm incomes would rise in developing countries with a move to free trade, thereby alleviating rural poverty. This occurs despite a terms of trade deterioration for developing countries that are net food importers or that enjoy preferential access to agricultural markets of high-income countries. The authors also show, for several large developing countries, the contribution of their own versus other countries' trade policies.

Publication Global Poverty Revisited Using 2021 PPPs and New Data on Consumption(Washington, DC: World Bank, 2025-06-05)Recent improvements in survey methodologies have increased measured consumption in many low- and lower-middle-income countries that now collect a more comprehensive measure of household consumption. Faced with such methodological changes, countries have frequently revised upward their national poverty lines to make them appropriate for the new measures of consumption. This in turn affects the World Bank’s global poverty lines when they are periodically revised. The international poverty line, which is based on the typical poverty line in low-income countries, increases by around 40 percent to $3.00 when the more recent national poverty lines as well as the 2021 purchasing power parities are incorporated. The net impact of the changes in international prices, the poverty line, and new survey data (including new data for India) is an increase in global extreme poverty by some 125 million people in 2022, and a significant shift of poverty away from South Asia and toward Sub-Saharan Africa. The changes at higher poverty lines, which are more relevant to middle-income countries, are mixed.Publication The Economic Value of Weather Forecasts: A Quantitative Systematic Literature Review(Washington, DC: World Bank, 2025-09-10)This study systematically reviews the literature that quantifies the economic benefits of weather observations and forecasts in four weather-dependent economic sectors: agriculture, energy, transport, and disaster-risk management. The review covers 175 peer-reviewed journal articles and 15 policy reports. Findings show that the literature is concentrated in high-income countries and most studies use theoretical models, followed by observational and then experimental research designs. Forecast horizons studied, meteorological variables and services, and monetization techniques vary markedly by sector. Estimated benefits even within specific subsectors span several orders of magnitude and broad uncertainty ranges. An econometric meta-analysis suggests that theoretical studies and studies in richer countries tend to report significantly larger values. Barriers that hinder value realization are identified on both the provider and user sides, with inadequate relevance, weak dissemination, and limited ability to act recurring across sectors. Policy reports rely heavily on back-of-the-envelope or recursive benefit-transfer estimates, rather than on the methods and results of the peer-reviewed literature, revealing a science-to-policy gap. These findings suggest substantial socioeconomic potential of hydrometeorological services around the world, but also knowledge gaps that require more valuation studies focusing on low- and middle-income countries, addressing provider- and user-side barriers and employing rigorous empirical valuation methods to complement and validate theoretical models.Publication The Macroeconomic Implications of Climate Change Impacts and Adaptation Options(Washington, DC: World Bank, 2025-05-29)Estimating the macroeconomic implications of climate change impacts and adaptation options is a topic of intense research. This paper presents a framework in the World Bank's macrostructural model to assess climate-related damages. This approach has been used in many Country Climate and Development Reports, a World Bank diagnostic that identifies priorities to ensure continued development in spite of climate change and climate policy objectives. The methodology captures a set of impact channels through which climate change affects the economy by (1) connecting a set of biophysical models to the macroeconomic model and (2) exploring a set of development and climate scenarios. The paper summarizes the results for five countries, highlighting the sources and magnitudes of their vulnerability --- with estimated gross domestic product losses in 2050 exceeding 10 percent of gross domestic product in some countries and scenarios, although only a small set of impact channels is included. The paper also presents estimates of the macroeconomic gains from sector-level adaptation interventions, considering their upfront costs and avoided climate impacts and finding significant net gross domestic product gains from adaptation opportunities identified in the Country Climate and Development Reports. Finally, the paper discusses the limits of current modeling approaches, and their complementarity with empirical approaches based on historical data series. The integrated modeling approach proposed in this paper can inform policymakers as they make proactive decisions on climate change adaptation and resilience.Publication Stanley Fischer Memorial Lecture: Geopolitics and Development—The World Bank ABCDE Conference(Washington, DC: World Bank, 2025-10-01)This paper provides a sweeping historical overview of how geopolitics has shaped economic development and global institutions, culminating in a forward-looking analysis of challenges facing the world in 2025. The paper argues that understanding economic history and the political economy is essential for effective policy making, as geopolitics—encompassing power politics, geography, security, and ecology—fundamentally influences development economics. It traces the dynamic interplay between geopolitics and development across major historical periods: from the European Age of Discovery and the rise of nation-states, through the world wars and the Bretton Woods era, to the Cold War and the age of globalization. It highlights how crises and conflicts have repeatedly transformed global economic systems, spurring new ideas and institutions. Looking ahead, the paper identifies key trends for 2025—fragmented global governance amid ongoing globalization (migration, climate change, and debt), shifting security contexts with territorial disputes and nuclear risks, and the intersection of energy, climate, demographics, and migration with development—as it predicts increased economic nationalism and regionalization in finance and trade. The paper concludes by emphasizing the adaptive role of multilateral institutions like the World Bank and the International Monetary Fund, advocating for a holistic approach to development economics that integrates political and economic institutions, governance, and both macro and micro markets.Publication Gender Gaps in the Performance of Small Firms: Evidence from Urban Peru(Washington, DC: World Bank, 2025-09-23)This paper estimates the gender gap in the performance of firms in Peru using representative data on both formal and informal firms. On average, informal female-led firms have lower sales, labor productivity, and profits compared to their male-led counterparts, with differences more pronounced when controlling for observable determinants of firm performance. However, gender gaps are only significant at the bottom of the performance distribution of informal firms, and these gaps disappear at the top of the distribution of informal firms and for formal firms. Possible explanations for the performance gaps at the bottom of the distribution include the higher likelihood of small, female-led firms being home-based, which is linked to lower profits, and their concentration in less profitable sectors. The paper provides suggestive evidence that household responsibilities play a key role in explaining the gender gap in firm performance among informal firms. Therefore, policies that promote access to care services or foster a more equal distribution of household activities may reduce gender productivity gaps and allow for a more efficient allocation of resources.

Publication Welfare and Poverty Effects of Global Agricultural and Trade Policies Using the Linkage Model(World Bank, Washington, DC, 2009-06)This paper analyzes the economic effects of agricultural price and merchandise trade policies around the world as of 2004 on global markets, net farm incomes, and national and regional economic welfare and poverty, using the global economy wide Linkage model, new estimates of agricultural price distortions for developing countries, and poverty elasticity's approach. It addresses two questions: to what extent are policies as of 2004 still reducing rewards from farming in developing countries and thereby adding to inequality across countries in farm household incomes? Are they depressing value added more in primary agriculture than in the rest of the economy of developing countries, and earnings of unskilled workers more than of owners of other factors of production, thereby potentially contributing to inequality and poverty within developing countries (given that farm incomes are well below non-farm incomes in most developing countries and that agriculture there is intensive in the use of unskilled labor)? Results are presented for the key countries and regions of the world and for the world as a whole. They reveal that, by moving to free markets, income inequality between countries will be reduced at least slightly, all but one-sixth of the gains to developing countries will come from agricultural policy reform, unskilled workers in developing countries the majority of whom work on farms will benefit most from reform, net farm incomes in developing countries will rise by 6 percent compared with 2 percent for non-agricultural value added, and the number of people surviving on less than US$1 a day will drop 3 percent globally.Publication Doha Merchandise Trade Reform : What’s at Stake for Developing Countries?(World Bank, Washington, DC, 2006-02)This paper provides new estimates of the global gains from multilateral trade reform and their distribution among developing countries in the presence of trade preferences. Particular attention is given to agriculture, as farmers constitute the poorest households in developing countries but are the most assisted in rich countries. The latest GTAP database (Version 6.05) and the LINKAGE model of the global economy are used to examine the impact first of current merchandise trade barriers and agricultural subsidies, and then of possible reform outcomes from the WTO's Doha Development Agenda. The results suggest moving to free global merchandise trade would boost real incomes in Sub-Saharan Africa proportionately more than in other developing countries or high-income countries, despite a terms of trade loss in parts of that region. Net farm incomes would rise substantially in that and other developing country regions, thereby alleviating rural poverty. A Doha partial liberalization could move the world some way toward those desirable outcomes, but more so the more developing countries themselves cut applied tariffs, particularly on agricultural imports.Publication Five Decades of Distortions to Agricultural Incentives(World Bank, Washington, DC, 2009-03)This chapter begins with a brief summary of the long history of national distortions to agricultural markets. It then outlines the methodology used to generate annual indicators of the extent of government interventions in markets, details of which are provided in Anderson and appendix A. A description of the economies under study and their economic growth and structural changes over recent decades is then briefly presented as a preface to the main section of the chapter, in which the nominal rates of assistance and consumer tax equivalents (NRA and CTE) estimates are summarized across regions and over the decades since the 1950s. These estimates are discussed in far more detail in the regional chapters that follow. A summary is also provided of an additional set of indicators of agricultural price distortions presented in chapter eleven that are based on the trade restrictiveness index first developed by Anderson and Neary (2005). In chapter twelve the focus shifts from countries to commodities, and all the various distortion indicators are used to provide a sense of how distorted are each of the key farm commodity markets globally. Then chapter thirteen uses the study's NRA and CTE estimates to provide a new set of results from a global economy-wide model that attempts to quantify the impacts on global markets, net farm incomes and welfare of the reforms since the early 1980s and of the policies still in place as of 2004. The chapter concludes by drawing on the lessons learned to speculate on the prospects for further reducing the disarray in world agricultural markets.Publication General Equilibrium Effects of Price Distortions on Global Markets, Farm Incomes and Welfare(World Bank, Washington, DC, 2008-09)Earnings from farming in many developing countries have been depressed by a pro-urban bias in own-country policies as well as by governments of richer countries favoring their farmers with import barriers and subsidies. Both sets of policies, which reduce national and global economic welfare and contribute to global inequality and poverty, have been undergoing reform since the 1980s. Using the linkage model of the global economy and modifications to the pre-release of version 7 of the Global Trade Analysis Project (GTAP) protection database for 2004, this paper seeks to compare the effect of those reforms to date with those that would come from removing remaining agricultural and trade policies. Two sets of results are thus presented: one showing the effects of policy reforms between 1980-84 and 2004, the other showing what the removal of remaining distortions as of 2004 could be. Both sets of results indicate improvements in the real value of agricultural output and exports, the real returns to farm land and unskilled labor, and real net farm incomes in most developing country regions despite the adverse effect on the international terms of trade for some developing countries that are net food importers or are enjoying preferential access to agricultural markets of high-income countries. Landowners in those high-income countries still offering their farmers price supports could readily afford to compensate them from the benefits of removing remaining agricultural protectionism.Publication Agricultural Distortion Patterns since the 1950s(World Bank, Washington, DC, 2009-05)This paper summarizes a new database that sheds light on the impact of trade-related policy developments over the past half century on distortions to agricultural incentives and thus also to consumer prices for food in 75 countries spanning the per capita income spectrum. Price support policies of advanced economies hurt not only domestic consumers and exporters of other products but also foreign producers and traders of farm products, and they reduce national and global economic welfare. On the other hand, the governments of many developing countries have directly taxed their farmers over the past half-century, both directly (e.g., export taxes) and also indirectly via overvaluing their currency and restricting imports of manufactures. Thus the price incentives facing farmers in many developing countries have been depressed by both own-country and other countries' agricultural price and international trade policies. The authors summarize these and realted stylized facts that can be drawn from a new World Bank database that is worthy of the attention of political economy theorists, historians and econometricians. These indicators can be helpful in addressing such questions as the following: where is there still a policy bias against agricultural production? To what extent has there been overshooting in the sense that some developing-country food producers are now being protected from import competition along the lines of the examples of earlier-industrializing Europe and Japan? What are the political economy forces behind the more-successful reformers, and how do they compare with those in less-successful countries where major distortions in agricultural incentives remain? And what explains the pattern of distortions across not only countries but also industries and in the choice of support or tax instruments within the agricultural sector of each country?

Publication China Country Climate and Development Report(World Bank Group, Washington DC, 2022-10)The China Country Climate and Development Report (CCDR) provides analysis and recommendations on integrating the country’s efforts to achieve high-quality development with the pursuit of emission reduction and climate resilience. Without adequate mitigation and adaptation efforts, climate risks will become a growing constraint to China’s long-term growth and prosperity, threatening to reverse development gains. Conversely, if efforts to tackle climate risks lead to a significant decline in growth and rising inequality, they would deprive millions of people of development and likely erode support for the reforms necessary to achieve a lasting economic transformation. Hence, China will need to grow and green its economy at the same time. This report offers policy options to achieve these dual objectives by easing inevitable trade-offs and maximizing potential synergies between China’s development and climate objectives.Publication Kyrgyz Republic : Overview of Climate Change Activities(Washington, DC, 2013-10)This overview of climate change activities in the Kyrgyz Republic is part of a series of country notes for five Central Asian countries that summarize climate portfolio in a number of sectors, namely agriculture, forestry, water, health, energy, and transport. Recognizing the nature and significance of climate change contribution to an increase in disaster risk, the note also looks into the development partners' approaches and measures in this area. This note further provides a brief overview of the Kyrgyz Republic climate context in terms of observed impacts and historical trends as well as climate projections specific to sectors that are considered to be essential to the country's economic development. Finally, the note assesses national policy and institutional context related to climate change as well as suggests potential ways forward that can help the Kyrgyz Republic mainstream climate considerations into development activities and planning and create public demand for climate actions.Publication World Bank Group Publications Editorial Style Guide 2020(World Bank, Washington, DC, 2020-03-04)The World Bank Group Publications Editorial Style Guide is an essential reference for manuscript editors (substantive and mechanical editors), proofreaders, and production editors. It is a supplement to other editorial references, in particular, The Chicago Manual of Style (annual subscription available online), 17th edition, and Merriam-Webster’s Collegiate Dictionary, 11th edition. It focuses on issues specific to the World Bank/International Bank for Reconstruction and Development (IBRD) or for which Chicago provides multiple options. The professional recommendations made in the guide are designed to meet the following objectives: • To ensure that every publication achieves a standard of professionalism appropriate for the World Bank and on par with the publications of similar organizations, • To ensure stylistic consistency, primarily within individual publications and secondarily across all World Bank publications, • To increase efficiency by eliminating the need to repeatedly address the same stylistic details for every publication.Publication The Evolution of Agricultural Trade Flows(2010-05-01)Earlier research showed that during the 1980s and 1990s most of the global agricultural trade expansion took place among the industrial countries and among countries within trade blocs. These were also periods of declining agricultural prices. These prices increased during the 2000s, there were continuous trade reforms, and many developing countries started to support their agricultural sectors. This paper analyzes trade flows during the past two decades, and tries to measure whether all these developments have changed the trade balances and the share of different groups within the global trade flows. In addition, it looks at the trade balances on food to see the impact of these changes on net food importing countries. In conclusion, unlike the case with manufacturing, developing countries have not been able to increase their export shares in agriculture as significantly. They have maintained their trade shares by primarily expanding exports to other developing countries.Publication West Bank and Gaza : Area C and the Future of the Palestinian Economy(Washington, DC, 2013-10-02)The Palestinian economy has experienced strong growth in recent years. This report examines the economic benefits of lifting the restrictions on movement and access, as well as other administrative obstacles, to Palestinian investment and economic activity in a region known as Area C. This region constitutes about 61 percent of the West Bank territory and was defined under the Oslo Peace Accords as the area that eventually would be transferred to the Palestinian Authority. Restrictions on economic activity in Area C of the West Bank have been particularly detrimental to the Palestinian economy. The Bank will focus on direct, sector-specific benefits, and also indirect benefits related to improvements in physical and institutional infrastructure, as well as spillover effects to other sectors of the Palestinian economy. The sectors examined are agriculture, Dead Sea minerals exploitation, stone mining and quarrying, construction, tourism, telecommunications, and cosmetics. Various physical, legal, regulatory and bureaucratic constraints that currently prevent investors from obtaining construction permits, and accessing land and water resources will be lifted. Current movement and access restrictions in force outside Area C prevent the easy export of Palestinian products and inhibit tourists and investors from accessing Area C. Further reforms by the Palestinian Authority will better enable potential investors to register businesses, enforce contracts, and acquire finance. Area C is important to future Palestinian economic development.
