Abstract
Since we introduced the term “middle-income trap” in 2006, it has become popular among policy makers and researchers. In May 2015, a search of Google Scholar returned more than 3,000 articles including the term and about 300 articles with the term in the title. This paper provides a (non-exhaustive) survey of this literature. The paper then discusses what, in retrospect, we missed when we coined the term. Today, based on developments in East Asia, Latin America, and Central Europe during the past decade, we would have paid more attention to demographic factors, entrepreneurship, and external institutional anchors. We would also make it clearer that to us, the term was as much the absence of a satisfactory theory that could inform development policy in middle-income economies as the articulation of a development phenomenon. Three-quarters of the people in the world now live in middle-income economies, but economists have yet to provide a reliable theory of growth to help policy makers navigate the transition from middle- to high-income status. Hybrids of the Solow-Swan and Lucas-Romer models are not unhelpful, but they are poor substitutes for a well-constructed growth framework.

    Global Poverty Revisited Using 2021 PPPs and New Data on Consumption
    (Washington, DC: World Bank, 2025-06-05) Foster, Elizabeth; Jolliffe, Dean Mitchell; Lara Ibarra, Gabriel; Lakner, Christoph; Tettah-Baah, Samuel
    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.

    The Economic Value of Weather Forecasts: A Quantitative Systematic Literature Review
    (Washington, DC: World Bank, 2025-09-10) Farkas, Hannah; Linsenmeier, Manuel; Talevi, Marta; Avner, Paolo; Jafino, Bramka Arga; Sidibe, Moussa
    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.

    The Macroeconomic Implications of Climate Change Impacts and Adaptation Options
    (Washington, DC: World Bank, 2025-05-29) Abalo, Kodzovi; Boehlert, Brent; Bui, Thanh; Burns, Andrew; Castillo, Diego; Chewpreecha, Unnada; Haider, Alexander; Hallegatte, Stephane; Jooste, Charl; McIsaac, Florent; Ruberl, Heather; Smet, Kim; Strzepek, Ken
    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.

    It’s Not (Just) the Tariffs: Rethinking Non-Tariff Measures in a Fragmented Global Economy
    (Washington, DC: World Bank, 2025-10-22) Taglioni, Daria; KEE, Hiau Looi
    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.

    An East Asian Renaissance : Ideas for Economic Growth
    (Washington, DC: World Bank, 2007) Kharas, Homi; Gill, Indermit; Bhattasali, Deepak; Brahmbhatt, Milan; Datt, Gaurav; Haddad, Mona; Mountfield, Edward; Tatucu, Radu; Vostroknutova, Ekaterina
    The region has been transformed by these developments, changing from a set of countries that rapidly integrated with the world to one that is also aggressively exploiting the sources of dynamism that lie within Asia. But countries in East Asia now face the domestic side-effects of rapid growth driven by international integration: congestion, conflict, and corruption. The challenge now is to complement global and regional integration with domestic integration. This requires ensuring vibrant cities that are not only linked to the outside world but also well-integrated domestically, strengthening social cohesion and reducing inequality, and providing clean governments which efficiently reinvest the economic returns that accompany fast growth.

    East Asian Visions : Perspectives on Economic Development
    (Washington, DC : World Bank, 2007) Huang, Yukon; Gill, Indermit; Kharas, Homi
    East Asian Visions: Perspectives on Economic Development is a collection of essays by 17 eminent East Asians who represent a broad spectrum of backgrounds and experiences. All are senior policy makers, statesmen, or scholars who have either had to deal with or think through some of the most critical financial and developmental issues confronting their countries and the region. Collectively, 10 of them have, at some point in their careers, been at the head of key ministries and central banks; nearly a dozen have been academics and scholars of distinction; several have served as ambassadors to the West and bring a more global strategic perspective; and many have been influential policy advisers and decision makers in governments and international financial agencies. Their essays reflect individual experiences at critical economic junctures and are occasionally quite personal, not surprising since each author selected a topic of his or her own choosing. Given their backgrounds, they have chosen to write about the highly diverse country experiences of East Asia, covering rich, middle income, and poor countries, and they speculate on how their countries fit into a rapidly changing region and globalizing world. Four themes permeate these essays: explaining East Asia's growth and developmental success; the powerful forces of regional integration and building efficiency versus vulnerability; avoiding domestic disintegration given growing public intolerance of increasing inequities, pollution, and corruption; and where will East Asia find its next generation of leaders.

    Shifting Patterns of Economic Growth and Rethinking Development
    (World Bank, Washington, DC, 2012-04) Lin, Justin Yifu; Rosenblatt, David
    This paper provides an historical overview of both the evolution of the economic performance of the developing world and the evolution of economic thought on development policy. The 20th century was broadly characterized by divergence between high-income countries and the developing world, with only a limited number (less than 10 percent of the economies in the world) managing to progress out of lower or middle-income status to high-income status. The last decade witnessed a sharp reversal from a pattern of divergence to convergence --particularly for a set of large middle-income countries. The latter phenomenon was also driven by increasing economic ties among developing countries, and on the intellectual scale, increased knowledge generation and sharing among the developing countries. Re-thinking development policy implies confronting these realities: 20th century economic divergence, the experience of the handful of success stories, and the recent rise of the multi-polar growth world. The paper provides descriptive data and a literature survey to document these trends. The paper also provides a brief survey of the role of multilateral institutions -- in particular, the World Bank -- in this changing context and offers suggestions on how they can adapt their strategies to improve development outcomes.

    From Flying Geese to Leading Dragons : New Opportunities and Strategies for Structural Transformation in Developing Countries
    (2011-06-01) Lin, Justin Yifu
    Economic development is a process of continuous industrial and technological upgrading in which any country, regardless of its level of development, can succeed if it develops industries that are consistent with its comparative advantage, determined by its endowment structure. The secret winning formula for developing countries is to exploit the latecomer advantage by building up industries that are growing dynamically in more advanced fast growing countries that have endowment structures similar to theirs. By following carefully selected lead countries, latecomers can emulate the leader-follower, flying-geese pattern that has served well successfully catching-up economies since the 18th century. The emergence of large middle-income countries such as China, India, and Brazil as new growth poles in the world, and their dynamic growth and climbing of the industrial ladder, offer an unprecedented opportunity to all developing economies with income levels currently below theirs --including those in Sub-Saharan Africa. Having itself been a "follower goose," China is on the verge of graduating from low-skilled manufacturing jobs and becoming a "leading dragon." That will free up nearly 100 million labor-intensive manufacturing jobs, enough to more than quadruple manufacturing employment in low-income countries. A similar trend is emerging in other middle-income growth poles. The lower-income countries that can formulate and implement a viable strategy to capture this new industrialization opportunity will set forth on a dynamic path of structural change that can lead to poverty reduction and prosperity.

    Learning from China's Rise to Escape the Middle-Income Trap : A New Structural Economics Approach to Latin America
    (World Bank, Washington, DC, 2012-08) Treichel, Volker; Lin, Justin Yifu
    This paper discusses the causes of the middle-income trap in Latin America and the Caribbean, identifies the challenges and opportunities for Latin America that come from China's rise, and draws lessons from New Structural Economics and the Growth Identification and Facilitation Framework to help Latin America escape the middle-income trap. Countries in Latin America and the Caribbean are caught in a middle-income trap due to their inability to structurally upgrade from low value-added to high value-added products. Governments in Latin America and the Caribbean should intervene in industries in which they have a comparative advantage, calibrating supporting policies in close collaboration with the private sector through public-private sector alliances. Through continuous structural upgrading in sectors intensive in factors such as natural resources, scientific knowledge, and unskilled labor, the region could achieve dynamic growth. This would require investments in education, research and development, and physical infrastructure. Therefore, industrial upgrading and diversification would be essential to avoid further de-industrialization arising from the competitive pressures of the rise of China, broaden the base for economic growth, and create the basis for further sustained reduction in unemployment, poverty and income inequality. Failure to do so would lead to a loss of competitiveness and risks of further de-industrialization.

    Breaking the Conflict Trap : Civil War and Development Policy
    (Washington, DC: World Bank and Oxford University Press, 2003) Collier, Paul; Elliott, V. L.; Hegre, Håvard; Hoeffler, Anke; Reynal-Querol, Marta; Sambanis, Nicholas
    Most wars are now civil wars. Even though international wars attract enormous global attention, they have become infrequent and brief. Civil wars usually attract less attention, but they have become increasingly common and typically go on for years. This report argues that civil war is now an important issue for development. War retards development, but conversely, development retards war. This double causation gives rise to virtuous and vicious circles. Where development succeeds, countries become progressively safer from violent conflict, making subsequent development easier. Where development fails, countries are at high risk of becoming caught in a conflict trap in which war wrecks the economy and increases the risk of further war. The global incidence of civil war is high because the international community has done little to avert it. Inertia is rooted in two beliefs: that we can safely 'let them fight it out among themselves' and that 'nothing can be done' because civil war is driven by ancestral ethnic and religious hatreds. The purpose of this report is to challenge these beliefs.

    Government Matters III : Governance Indicators for 1996-2002
    (World Bank, Washington, DC, 2003-08) Kaufmann, Daniel; Kraay, Aart; Mastruzzi, Massimo
    The authors present estimates of six dimensions of governance covering 199 countries and territories for four time periods: 1996, 1998, 2000, and 2002. These indicators are based on several hundred individual variables measuring perceptions of governance, drawn from 25 separate data sources constructed by 18 different organizations. The authors assign these individual measures of governance to categories capturing key dimensions of governance and use an unobserved components model to construct six aggregate governance indicators in each of the four periods. They present the point estimates of the dimensions of governance as well as the margins of errors for each country for the four periods. The governance indicators reported here are an update and expansion of previous research work on indicators initiated in 1998 (Kaufmann, Kraay, and Zoido-Lobat 1999a,b and 2002). The authors also address various methodological issues, including the interpretation and use of the data given the estimated margins of errors.

    Governance Matters VIII : Aggregate and Individual Governance Indicators 1996–2008
    (2009-06-01) Kaufmann, Daniel; Kraay, Aart; Mastruzzi, Massimo
    This paper reports on the 2009 update of the Worldwide Governance Indicators (WGI) research project, covering 212 countries and territories and measuring six dimensions of governance between 1996 and 2008: Voice and Accountability, Political Stability and Absence of Violence/Terrorism, Government Effectiveness, Regulatory Quality, Rule of Law, and Control of Corruption. These aggregate indicators are based on hundreds of specific and disaggregated individual variables measuring various dimensions of governance, taken from 35 data sources provided by 33 different organizations. The data reflect the views on governance of public sector, private sector and NGO experts, as well as thousands of citizen and firm survey respondents worldwide. The authors also explicitly report the margins of error accompanying each country estimate. These reflect the inherent difficulties in measuring governance using any kind of data. They find that even after taking margins of error into account, the WGI permit meaningful cross-country comparisons as well as monitoring progress over time. The aggregate indicators, together with the disaggregated underlying indicators, are available at www.govindicators.org.

    Governance Matters IV : Governance Indicators for 1996-2004
    (World Bank, Washington, DC, 2005-06) Kaufmann, Daniel; Kraay, Aart; Mastruzzi, Massimo
    The authors present the latest update of their aggregate governance indicators, together with new analysis of several issues related to the use of these measures. The governance indicators measure the following six dimensions of governance: (1) voice and accountability; (2) political instability and violence; (3) government effectiveness; (4) regulatory quality; (5) rule of law, and (6) control of corruption. They cover 209 countries and territories for 1996, 1998, 2000, 2002, and 2004. They are based on several hundred individual variables measuring perceptions of governance, drawn from 37 separate data sources constructed by 31 organizations. The authors present estimates of the six dimensions of governance for each period, as well as margins of error capturing the range of likely values for each country. These margins of error are not unique to perceptions-based measures of governance, but are an important feature of all efforts to measure governance, including objective indicators. In fact, the authors give examples of how individual objective measures provide an incomplete picture of even the quite particular dimensions of governance that they are intended to measure. The authors also analyze in detail changes over time in their estimates of governance; provide a framework for assessing the statistical significance of changes in governance; and suggest a simple rule of thumb for identifying statistically significant changes in country governance over time. The ability to identify significant changes in governance over time is much higher for aggregate indicators than for any individual indicator. While the authors find that the quality of governance in a number of countries has changed significantly (in both directions), they also provide evidence suggesting that there are no trends, for better or worse, in global averages of governance. Finally, they interpret the strong observed correlation between income and governance, and argue against recent efforts to apply a discount to governance performance in low-income countries.
