Abstract
What is the pathway to development in a world marked by rising economic nationalism and less international integration? This paper answers this question within a framework that emphasizes the role of demand-side constraints on national development, which is identified with sustained poverty reduction. In this framework, development is linked to the adoption of an increasing returns to scale technology by imperfectly competitive firms that need to pay the fixed setup cost of switching to that technology. Sustained poverty reduction is measured as a continuous decline in the share of the population living below $1.90/day purchasing power parity in 2011 US dollars over a five year period. This outcome is affected in a statistically significant and economically meaningful way by domestic market size, which is measured as function of the income distribution, and international market size, which is measured as a function of legally-binding provisions to international trade agreements, including the General Agreement on Tariffs and Trade, the World Trade Organization and 279 preferential trade agreements. Counterfactual estimates suggest that, in the absence of international integration, the average resident of a low or lower-middle income country does not live in a market large enough to experience sustained poverty reduction. Domestic redistribution targeted towards generating a larger middle class can partially compensate for the lack of an international market.

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 Marshall Plan: Then and Now(Washington, DC: World Bank, 2025-10-14)This paper is a product of the Development Policy Team, Development Economics.

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 It’s Not (Just) the Tariffs: Rethinking Non-Tariff Measures in a Fragmented Global Economy(Washington, DC: World Bank, 2025-10-22)As tariffs have declined, non-tariff measures (NTMs) have become central to trade policy, especially in high-income countries and regulated sectors like food and green technologies. Although NTMs may serve legitimate goals, they could also sort countries and firms into or out of markets based on compliance capacity and differences in product mix. Documenting recent advances in the estimation of ad valorem equivalents (AVEs), this paper uncovers new patterns of use and exposure of NTMs. High-income countries rely more heavily on NTMs relative to tariffs, while low- and middle-income countries face steeper AVEs on their exports. Firm-level evidence shows that NTMs disproportionately affect smaller firms, leading to market exit and concentration. Poorly designed NTMs can harm productivity and welfare, while coordinated, capacity-aware use can deliver inclusive outcomes. Policy design, transparency, and diagnostics must evolve to reflect the growing role—and risks—of NTMs in a fragmented global trade landscape.

Publication Global Poverty and Distributional Impacts of Agricultural Distortions(World Bank, Washington, DC, 2009-06)This paper assesses the potential impacts of the removal of agricultural and other trade distortions using a newly developed dataset and methodological approach for evaluating the global poverty and inequality effects of policy reforms. It finds that liberalization of agriculture will increase global extreme poverty (US$1 a day) slightly and by almost 1 percent if other goods trade is also liberalized; but the number of people living on less than $2 a day will fall by almost 1 percent. Beneath these small aggregate changes, most countries witness a substantial reduction in poverty while South Asia where half of the world's poor reside will experience an increase in extreme (but not moderate) poverty incidence due to high rates of protection afforded to its unskilled labor-intensive agricultural sectors. The distributional changes also are projected to be mild, but again exhibit a strong regional pattern: inequality falls in Latin America, which is characterized by high initial inequality, and rises in South Asia, has relatively low income inequality.Publication Is the Global Economy Deglobalizing?(World Bank, Washington, DC, 2023-04-10)Data on global trade as well as capital and labor flows indicate a slowdown, but not reversal, of globalization post the 2008–09 financial crisis. Yet profound changes in the policy environment and public sentiment in the largest economies over the past five years suggest the beginning of a new era. Increasing anxiety about the labor market effects of import competition from low-wage countries, especially China, laid the groundwork, but was not the catalyst for the reversal in attitudes towards globalization. Similarly, the COVID pandemic provided novel arguments against free trade based on global supply chain resilience, but neither the pandemic nor short run policy response had enduring effects on trade flows. Global trade was remarkably resilient during the pandemic and that supply shortages would likely have been more severe in the absence of international trade. After a temporary decline in 2020, global trade in goods and services increased sharply in 2021. Russia’s invasion of Ukraine raised new concerns about national security and the exposureof supply chains to geopolitical risk. This was followed by demands to diversify away from “non-friendly” countries and to the employment of trade policy, export restrictions in particular, to halt China’s technological development. The future of globalization is highly uncertain at this point, but these new policies will likely slow global growth, innovation, and poverty reduction even if they benefit certain industries in certain countries. Regarding resilience, the main goal of recent trade policy changes, measures of trade volatility or concentration can be helpful, but resilience will be elusive as long as we lack benchmarks against which policy performance can be measured.Publication Demand-Side Management in China's Restructured Power Industry : How Regulation and Policy Can Deliver Demand-Side Management Benefits to a Growing Economy and a Changing Power System(World Bank, Washington, DC, 2005-12)China expects its gross domestic product in 2020 to be four times that of 2000. Limits on energy resources and China's environmental needs require that electricity use grow at a much lower rate than the economy. Demand-side management (DSM) is a critical component of China's sustainable development. It is a set of tools and practices taken by utilities to influence the amount and/or timing of customers' energy demand in order to utilize scarce electric supply resources most efficiently. DSM is a proven method of meeting economic goals in an environmentally sustainable way, and it is also a fast and effective way to address power shortages. This report reviews China's experience with DSM, explores the barriers to and the potential for new demand-side investment, and examines successful DSM strategies in other countries. It suggests the near-and long-term regulatory and government policies needed to support substantial new investment in comprehensive, cost-effective programs for end-use efficiency and load management.Publication A Globalized Market--Opportunities and Risks for the Poor : Global Poverty Report 2001(World Bank, Washington, DC, 2001-07)The Global Poverty Report considers the effects of globalizing markets on poverty in developing countries. It outlines the channels through which increased trade openness can affect poverty and examines the evidence from four regions: Sub-Saharan Africa, Asia and the Pacific, Eastern Europe and Central Asia, and Latin America and the Caribbean. Written at the request of the G8, the report is the result of a joint effort of the regional development banks, the World Bank, and the International Monetary Fund. Increased openness can affect an economy in various ways, creating opportunities for the poor as well as risks. First, it can affect the prices of goods and services that the poor consume and produce, benefiting those who are net consumers of goods that become cheaper and those who can obtain higher prices for their products on international markets. Second, it can affect the demand for and returns to factors of production that the poor have to offer, such as labor. Third, it can affect government revenue and the resources available for antipoverty programs. Fourth, it can influence the potential for economic growth, which in turn affects poverty. Fifth, the short-term costs of transition, as well as the possible increased volatility of growth stemming from the opening up of markets, may increase the need for social protection mechanisms. Comprehensive trade reform can help reduce poverty when it is part of a set of reforms that improve the domestic macroeconomic and investment climate, enhance infrastructure and technology, and contribute to the provision of knowledge and skills. However, these effects vary significantly across countries, regions, and groups within countries, which makes it difficult to generalize about the effects of trade liberalization on poverty.Publication Australia's Seasonal Worker Program : Demand-side Constraints and Suggested Reforms(World Bank Group, Washington, DC, 2015-01)The Seasonal Worker Program (SWP), which was informed by the Pacific Seasonal Worker Pilot Scheme (PSWPS), represents the first effort by an Australian government to explicitly open low-skilled work opportunities to Pacific Islanders since Federation. The PSWPS was largely modelled on the success of New Zealand s equivalent RSE scheme. The PSWPS ran over a four year period in the horticulture sector (2008-2012) and had a total cap of 2,500 workers. Despite the widespread success and rapid expansion of the RSE, the PSWPS got off to a slow start and never managed to reach its full potential. This paper aims to determine whether the factors constraining demand have changed since the PSWPS and what reforms could help lift employer demand. It does so through assessing the views of a sample of employers and industry bodies across the horticulture industry. The trial sectors are not covered. The study is divided into five sections. Section two describes the origin, design and features of both the PSWPS and SWP. Section three provides a brief overview of the survey. Section four presents the key results and discusses how these compare with those collected by Hay and Howes (2012). Section five explores a possible way forward by suggesting a series of reforms based on the core set of findings.
