Abstract
Accurate trade data remain central for empirical investigations of international trade and informed formulation of trade policies. However, discrepancies in trade reporting, stemming from reasons such as logistics to deliberate misclassification, pose challenges to obtaining an accurate representation of trade activities. This paper provides a systematic examination of these discrepancies by using the Discrepancy Index, a measure of bilateral asymmetry in trade reporting. First, the paper proposes a rich set of country- and product-level indicators that capture both the frequency of misreporting and its impact on the overall recorded trade value. Second, it demonstrates how the Discrepancy Index database can aid analysis and resolve data reliability issues in international trade. This comprehensive data set is used to analyze the general trends in trade data reporting and its reliability, providing empirical insights into the nature and extent of reporting discrepancies. Finally, the paper demonstrates the practical application of the developed discrepancy database and aggregate indicators through case studies of Senegal and the trade relationship between Madagascar and France, shedding light on reporter-specific instances. The paper seeks to equip trade analysts and researchers with tools and resources to make informed decisions on the use of reported trade data and their mirror. In doing so, the study contributes to the broader endeavor of enhancing the reliability of international trade data, thereby contributing to a more accurate empirical investigation of global trade patterns and their policy ramifications.

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 South Africa’s Fragmented Cities: The Unequal Burden of Labor Market Frictions(Washington, DC: World Bank, 2026-01-08)Using high-resolution administrative, census, and satellite data, this paper shows that South African cities are characterized by spatial mismatches between where people live and where jobs are located, relative to 20 global peers. Areas within 5 kilometers of commercial centers have 9,300 fewer residents per square kilometer than expected, which is 60 percent below the global median. Poor, dense neighborhoods are most affected. In Johannesburg, a 10-percentile increase in distance from the nearest business hub corresponds to a 3.7-percentile drop in asset wealth (a proxy of household wellbeing) and 4.9-percentile drop in employment. In Cape Town, the declines are 4.0 and 3.7 percentiles, respectively. Employment is 87 percent lower in the poorest decile than the richest in Johannesburg and 61 percent lower in Cape Town. These findings suggest that South Africa’s spatial organization of people and economic activity constrains agglomeration and reinforces inequality. This methodology provides a scalable and standardized data-driven framework to analyze spatial accessibility and agglomeration frictions in complex, data-constrained urban systems.Publication The Evolution of Local Participatory Democracy in Nepal(Washington, DC: World Bank, 2025-11-05)Nepal is, according to its constitution, among the world’s most decentralized countries, with a long and complex tradition of local-level public participation. This paper traces the evolution of Nepal’s modern participatory institutions, examining the extent to which they are “induced” by external interventions versus being “organically” rooted in indigenous practices. The paper identifies three broad phases: an initial focus on participation in project implementation; a subsequent phase that expanded citizen engagement; and a third phase of citizen empowerment, culminating in the 2015 federal constitution, which granted unprecedented local autonomy. The analysis yields five key findings. First, over the past 50 years, successive reforms have progressively expanded opportunities for citizens to influence local decision-making. Second, these reforms have integrated traditional participatory mechanisms into formal institutions of local government. Third, although central-level initiatives exist, most participatory platforms continue to operate at the local level. Fourth, the federal constitution has created a new landscape of local democracy, embedding autonomy and accountability. Fifth, although they are still valued in many ethnic and territorial communities, traditional participatory practices are gradually disappearing. The paper concludes by offering policy recommendations to help donor agencies and governments strengthen Nepal’s democratic trajectory. It argues that effective interventions should build on Nepal’s deep participatory traditions while recognizing the constitutional reality of far-reaching local autonomy.Publication Institutional Capacity for Policy Implementation: An Analytical Framework(Washington, DC: World Bank, 2026-01-07)State capacity is an important prerequisite for policy implementation, yet at the country level it is difficult to measure, assess, and reform. This paper proposes a focus on institutional capacity: the ability of public institutions to implement the specific policy mandates for which they are responsible. Based on a review of existing literature, the paper defines the different dimensions that compose institutional capacity and groups them into two cross-cutting categories: organizational dimensions (personnel, financial resources, information systems, and management practices) and governance dimensions (transparency, independence, and accountability). The paper proposes measures for organizational and governance dimensions using existing data, shows intra-institutional variation of these measures within countries, and discusses how new data could be collected for better measurement of these concepts. Finally, the paper illustrates how the framework can be used to diagnose the sources of common problems related to weak policy implementation.Publication Closing the Gender Gap in Entrepreneurship: Overcoming Challenges in Law and Practice for Female Entrepreneurs(Washington, DC: World Bank, 2026-01-07)Despite significant strides toward gender equality, women around the world continue to encounter systemic obstacles that hinder their entrepreneurial success. This paper systematically reviews the literature on the barriers female entrepreneurs face and the solutions proposed to overcome these challenges. It discusses institutional factors, financial factors, human capital factors, and social and cultural factors. The literature overview is complemented by a series of stylized facts that illustrate how overcoming some of these existing barriers is correlated with improved women’s entrepreneurship and female labor force participation, drawing on the World Bank’s Women, Business and the Law database as well as the World Bank’s Enterprise Surveys. The findings underscore the need for creating an enabling environment where women can thrive as entrepreneurs.

Publication Estimating the Gravity Model When Zero Trade Flows are Frequent and Economically Determined(World Bank, Washington, DC, 2015-06)This paper evaluates the performance of alternative estimators of the gravity equation when zero trade flows result from economically-based data-generating processes with heteroscedastic residuals and potentially-omitted variables. In a standard Monte Carlo analysis, the paper finds that this combination can create seriously biased estimates in gravity models with frequencies of zero frequently observed in real-world data, and that Poisson Pseudo-Maximum-Likelihood models can be important in solving this problem. Standard threshold–Tobit estimators perform well in a Tobit-based data-generating process only if the analysis deals with the heteroscedasticity problem. When the data are generated by a Heckman sample selection model, the Zero-Inflated Poisson model appears to have the lowest bias. When the data are generated by a Helpman, Melitz, and Rubinstein-type model with heterogeneous firms, a Zero-Inflated Poisson estimator including firm numbers appears to provide the best results. Testing on real-world data for total trade throws up additional puzzles with truncated Poisson Pseudo-Maximum-Likelihood and Poisson Pseudo-Maximum-Likelihood estimators being very similar, and Zero-Inflated Poisson and truncated Poisson Pseudo-Maximum-Likelihood identical. Repeating the Monte Carlo analysis taking into account the high frequency of very small predicted trade flows in real-world data reconciles these findings and leads to specific recommendations for estimators.Publication Are Natural Resources Cursed? An Investigation of the Dynamic Effects of Resource Dependence on Institutional Quality(World Bank, Washington, DC, 2012-07)This paper examines whether natural resource dependence has a negative influence on various indicators of institutional quality when controlling for the potential effects of other geographic, economic and cultural initial conditions. Analysis of a panel of countries from 1996 to 2010 indicates that a high degree of resource dependence, measured as the share of mineral fuel exports in a country's total exports, is associated with worse government effectiveness, as well as with reduced levels of competition across the economy. Furthermore, estimation of long-run elasticities suggests that government effectiveness and the intensity of domestic competition decrease over time as the dependence on natural resources increases. An illustration of the Russian case shows that the negative effects accumulate in the long run, leading to a worse deterioration of government effectiveness in Russia than in Canada, a country with a comparable resource endowment but far better overall institutional quality. This result is corroborated by a significant negative correlation found between regional resource dependence and an indicator of regulatory capture in Russian regions, which indicates that the regulatory environment is more likely to be subverted in regions that are more dependent on extractive industries. Overall, the findings would be consistent with a situation in which a generally weak institutional environment would allow resource interests to wield the bidding power accruing from export revenues to subvert the content of laws and regulations, as well as their enforcement. The fact that this is associated with negative externalities for the rest of the economy, notably by undermining a level playing field across non-resource sectors, sheds light on a potential channel for the resource curse.Publication Trade Causes Growth in Sub-Saharan Africa(World Bank, Washington, DC, 2012-03)In the 1990s the mainstream consensus was that trade causes growth. Subsequent research shed doubt on the consensus view, as evidence suggested that the identification of the effect of trade on growth was problematic in the existing literature. This paper contributes to this debate by focusing on growth in Sub-Saharan Africa. It estimates the effect of openness to international trade on economic growth with panel data. Employing instrumental variables techniques that correct for endogeneity bias, the empirical evidence suggests that within-country variations in trade openness cause economic growth: a 1 percentage point increase in the ratio of trade over gross domestic product is associated with a short-run increase in growth of approximately 0.5 percent per year; the long-run effect is larger, reaching about 0.8 percent after ten years. These results are robust to controlling for country and time fixed effects as well as political institutions.Publication The Growth of China and India in World Trade : Opportunity or Threat for Latin America and the Caribbean?(World Bank, Washington, DC, 2007-08)This paper studies the relationship between the growth of China and India in world merchandise trade and Latin American and Caribbean commercial flows from two perspectives. First, the authors focus on the opportunity that China and India's markets have offered Latin American and Caribbean exporters during 2000-2004. Second, empirical analyses examine the partial correlation between Chinese and Indian bilateral trade flows and Latin American and Caribbean trade with third markets. Both analyses rely on the gravity model of international trade. Econometric estimations that control for the systematic correlation between expected bilateral trade volumes and the size of their regression errors, as well as importer and exporter fixed effects and year effects, provide consistent estimates of the relevant parameters for different groups of countries in Latin America and the Caribbean. Results suggest that the growth of the two Asian markets has produced large opportunities for Latin American and Caribbean exporters, which nevertheless have not been fully exploited. The evidence concerning the effects of Chinese and Indian trade with third markets is not robust, but there is little evidence of negative effects on Latin American and Caribbean exports of non-fuel merchandise. In general, China's and to a large extent India's growing presence in world trade has been good news for Latin America and the Caribbean, but some of the potential benefits remain unexploited.Publication Over the Hedge : Exchange Rate Volatility, Commodity Price Correlations, and the Structure of Trade(2011-03-01)A long empirical literature has examined the idea that, in the absence of hedging mechanisms, currency risk should have an adverse effect on the export volumes of risk averse exporters. But there are no clear conclusions from this literature, and the current consensus seems to be that there is at most a weak negative effect of exchange rate volatility on aggregate trade flows. However, most of this literature examines the impact of exchange rate volatility on aggregate trade flows, implicitly assuming a uniform impact of this volatility on exporters across sectors. This paper explots the fact that, if exchange rate volatility is detrimental for trade, firms exporting goods that offer a natural hedge against exchange rate fluctuations -- i.e. those whose international price is negatively correlated with the nominal exchange rate of the country where they operate -- should be relatively benefited in environments of high exchange rate volatility, and capture a larger share of the country's export basket. This hypothesis is tested using detailed data on the composition of trade of 132 countries at 4-digit SITC level. The results show that the commodities that offer natural hedge capture a larger share of a country's export basket when the exchange rate is volatile, but there is only weak evidence that the availability of financial derivatives to hedge currency risk reduces the importance of a sector's natural hedge.

Publication Statistical Performance Indicators and Index(World Bank, Washington, DC, 2021-03)The World Bank’s Statistical Capacity Index has been widely employed to measure country statistical capacity since its inception two decades ago. This paper builds on the existing advantages of the Statistical Capacity Index, conceptually and empirically, to offer new statistical performance indicators and the Statistical Performance Index, which can better measure a country’s statistical performance. The new index has clearer conceptual motivations, employs a stronger mathematical foundation, and significantly expands the number of indicators and countries covered. The paper further provides empirical evidence that illustrates the strong correlation of the new index with other commonly used development indicators of human capital, governance, poverty, and inequality. The framework can accommodate future directions to improve the index as the global data landscape evolvesPublication Data Transparency and Growth in Developing Economies during and after the Global Financial Crisis(World Bank, Washington, DC, 2020-12)The study explores the effects of data transparency on economic growth for developing economies over a unique time period—at the onset of the 2007–2009 global financial crisis and thereafter. Data transparency is defined as the timely production of credible statistics as measured by the Statistical Capacity Indicator. The paper finds that data transparency has a positive effect on real gross domestic product per capita during a period of considerable uncertainty. The estimates indicate an elasticity of the magnitude of 0.03 percent per year, which is much larger than the elasticity of trade openness and schooling in the estimation sample. The empirics employ a variety of econometric estimators, including dynamic panel and cross-sectional instrumental variables estimators, with the latter approach yielding a higher estimated elasticity. The findings are robust to the inclusion of several factors in addition to political institutions and exogenous commodity-price and external debt-financing shocks.Publication Evolution of the World Bank’s Thinking on Governance(World Bank, Washington, DC, 2016-01)The preparation work for the 2017 World Development Report on Governance and the Law in 2016 will coincide with the 25th anniversary of the World Bank’s decision to broaden its ongoing work on public sector management to embrace key issues of governance in the Bank’s borrowing countries. This paper provides a broad overview of the major Bank reports on governance that went through a review process at a sufficiently high level in the institution that they can reasonably be described as reflecting the Bank’s considered views at the time on the subject. The objective is to review the evolution of the Bank’s thinking on governance and assess the relevance and effectiveness of the work and its implications for the forthcoming World Development Report. Section two of this paper begins with a brief account of how the Bank came to focus on issues of governance, reviewing the major upheaval of governance in many of the Bank’s borrowing countries in the 1980s, the legal constraints the Articles of Agreement impose on the Bank’s work on governance, and a brief overview of the Bank’s initial policy statement on governance issued to the Bank’s Board in June 1991. Section three reviews major Bank work on governance as reflected in successive World Development Reports and examines the Bank’s analysis of the issue of corruption, reviewing how the Bank’s thinking on this symptom of poor governance has evolved. Section four steps back to assess what the Bank got right and some of the issues it missed or failed to address adequately. Section five draws attention to the dramatic changes experienced by the developing world in these past 25 years, and points to the need to better understand the implications of these changes for the governance context facing developing countries.Publication Governance in Sub-Saharan Africa in the 21st Century(Washington, DC: World Bank, 2024-03-04)What can be learned from the governance trajectory of African countries since the beginning of the 21st century What is the quality of governance on the African continent and how does it shape development The first decade of the millennium saw promising growth and poverty reduction in much of the continent. Yet, Sub-Saharan Africa has also been the stage of a stream of governance reform failures and policy reversals, and many countries continue to suffer from the consequences of poor governance. This paper explores the dynamics of governance reform on the continent over the past two decades and points to four key trends. First, effective state institutions, capable of maintaining peace, fostering growth, and delivering services, have developed unevenly. Second, progress has been made on enhancing the inclusiveness and accountability of institutions, but it remains constrained by the weakness of checks and balances and the persistence of patterns of centralized and exclusive power arrangements. Third, civic capacity has risen considerably, but the inability of institutions to respond to social expectations and political mobilization threatens to turn liberal civic engagement into distrust, populism, and radicalization. Fourth, the combination of these three trends contributes to the rise of political instability, which constitutes a major threat for the continent.Publication Economic Governance Improvements and Sovereign Financing Costs in Developing Countries(World Bank, Washington, DC, 2021-05)Low- and middle-income country governments are increasingly tapping the global debt capital markets. This is increasing the amount of finance available for development, but at a considerably higher cost than traditional external borrowing on concessional terms. Using a novel methodology based on estimating sovereign credit ratings using the Moody’s scorecard, and examining the associations between these ratings and the World Bank’s Country Policy and Institutional Assessment scores, this paper examines how making improvements in the quality of economic policies and institutions can help lower governments’ financing costs. This method aims to overcome the small-sample problem due to the number of rated developing country sovereigns still being relatively limited (although growing). Better economic governance Country Policy and Institutional Assessment scores are associated with better estimated ratings and materially lower financing costs; on average, improvements that are sufficient to increase the Country Policy and Institutional Assessment economic governance indicator score by one point are associated with interest costs that are lower by about 40 basis points, even setting aside the direct impact on ratings of better governance indicators. There are many reasons why improving governance is a good thing. Among them is the potential payoff to the public purse — savings of $40 million or more on a standard $1 billion, 10-year bond.
