Abstract
Do Southern African Development Community countries trade enough with each other and with the rest of the world? Although its share of world trade has fallen, appropriate benchmarking shows that, controlling for gross domestic product and other characteristics, Southern African Development Community countries have experienced an increase in openness that is comparable to other developing countries. Once market size and geography are taken into account, trade between Southern African Development Community countries is actually high. Southern African Development Community countries also trade more products with each other than they do with the rest of the world. In this sense, and contrary to stylized fears, the Southern African Development Community region is quite integrated. Although the Southern African Development Community has reduced its tariffs, the structure remains complex and could be lowered on intermediates. Other impediments make it costly and difficult to move goods, but are at levels that are comparable with countries at similar levels of development. Although this may be surprising, there is still scope for improvement and the disadvantageous geography of the Southern African Development Community makes it important for other trade impediments to be reduced.

Publication The Future of Poverty(Washington, DC: World Bank, 2025-07-15)Climate change is increasingly acknowledged as a critical issue with far-reaching socioeconomic implications that extend well beyond environmental concerns. Among the most pressing challenges is its impact on global poverty. This paper projects the potential impacts of unmitigated climate change on global poverty rates between 2023 and 2050. Building on a study that provided a detailed analysis of how temperature changes affect economic productivity, this paper integrates those findings with binned data from 217 countries, sourced from the World Bank’s Poverty and Inequality Platform. By simulating poverty rates and the number of poor under two climate change scenarios, the paper uncovers some alarming trends. One of the primary findings is that the number of people living in extreme poverty worldwide could be nearly doubled due to climate change. In all scenarios, Sub-Saharan Africa is projected to bear the brunt, contributing the largest number of poor people, with estimates ranging between 40.5 million and 73.5 million by 2050. Another significant finding is the disproportionate impact of inequality on poverty. Even small increases in inequality can lead to substantial rises in poverty levels. For instance, if every country’s Gini coefficient increases by just 1 percent between 2022 and 2050, an additional 8.8 million people could be pushed below the international poverty line by 2050. In a more extreme scenario, where every country’s Gini coefficient increases by 10 percent between 2022 and 2050, the number of people falling into poverty could rise by an additional 148.8 million relative to the baseline scenario. These findings underscore the urgent need for comprehensive climate policies that not only mitigate environmental impacts but also address socioeconomic vulnerabilities.Publication Central Bank Independence and Sovereign Borrowing(Washington, DC: World Bank, 2025-07-25)This paper studies the impact of central bank independence on sovereign borrowing, using an index that captures institutional constraints on central bank lending to the government across 155 countries from 1972 to 2023. The findings show that tighter lending to the executive significantly reduces sovereign interest rates and raises the debt-to-gross domestic product ratio in developing countries. These effects reflect the executive’s improved ability to borrow at lower costs under greater central bank independence. The results are robust to multiple tests, but there are no significant effects in advanced economies. From a policy perspective, the results highlight the key role of independent central banks as catalysts for reducing governments’ borrowing costs and enhancing the government’s borrowing capacity.Publication Disentangling the Key Economic Channels through Which Infrastructure Affects Jobs(Washington, DC: World Bank, 2025-04-03)This paper takes stock of the literature on infrastructure and jobs published since the early 2000s, using a conceptual framework to identify the key channels through which different types of infrastructure impact jobs. Where relevant, it highlights the different approaches and findings in the cases of energy, digital, and transport infrastructure. Overall, the literature review provides strong evidence of infrastructure’s positive impact on employment, particularly for women. In the case of electricity, this impact arises from freeing time that would otherwise be spent on household tasks. Similarly, digital infrastructure, particularly mobile phone coverage, has demonstrated positive labor market effects, often driven by private sector investments rather than large public expenditures, which are typically required for other large-scale infrastructure projects. The evidence on structural transformation is also positive, with some notable exceptions, such as studies that find no significant impact on structural transformation in rural India in the cases of electricity and roads. Even with better market connections, remote areas may continue to lack economic opportunities, due to the absence of agglomeration economies and complementary inputs such as human capital. Accordingly, reducing transport costs alone may not be sufficient to drive economic transformation in rural areas. The spatial dimension of transformation is particularly relevant for transport, both internationally—by enhancing trade integration—and within countries, where economic development tends to drive firms and jobs toward urban centers, benefitting from economies scale and network effects. Turning to organizational transformation, evidence on skill bias in developing countries is more mixed than in developed countries and may vary considerably by context. Further research, especially on the possible reasons explaining the differences between developed and developing economies, is needed.Publication Crowding Out and Banking Crises(Washington, DC: World Bank, 2025-07-22)This paper studies the effect of government issuance on firm issuance during banking crises using transaction-level bond and loan data from 66 countries between 1991 and 2017. Governments rarely issue loans, preferring to issue in bond markets. In contrast, firms receive most of their financing from banks. During banking crises, as the supply of domestic loans decreases, firms switch to issuing bonds in domestic markets. The paper uses a novel instrument based on maturing debt to overcome the potential endogeneity of government issuance. The findings show that firms must compete with the government for funds in the domestic bond market and are crowded out from this market as a result. This happens not only in developing countries, but in advanced countries as well. The paper also shows that firms with the ability to tap international debt markets switch to these markets when crowding out occurs in domestic bond markets. Lastly, the paper shows that more developed domestic bond markets mitigate, but do not eliminate, the degree to which crowding out occurs.Publication Designing and Analyzing Powerful Experiments(Washington, DC: World Bank, 2025-07-22)This paper offers practical advice on how to improve statistical power in randomized experiments through choices and actions researchers can take at the design, implementation, and analysis stages. At the design stage, the choice of estimand, choice of treatment, and decisions that affect the residual variance and intra-cluster correlation can all affect power for a given sample size. At the implementation stage, researchers can boost power through increasing compliance with treatment, reducing attrition, and improving outcome measurement. At the analysis stage, power can be increased through using different test statistics or estimands, through the choice of control variables, and through incorporating informative priors in a Bayesian analysis. A key message is that it does not make sense to talk of “the” power of an experiment. A study can be well-powered for one outcome or estimand, but not others, and a fixed sample size can yield very different levels of power depending on researcher decisions.

Publication Economic Partnership Agreements and the Export Competitiveness of Africa(World Bank, Washington, DC, 2008-05)Trade can be a key driver of growth for African countries, as it has been for those countries, particularly in East Asia, that have experienced high and sustained rates of growth. Economic partnership agreements with the European Union could be instrumental in a competitiveness framework, but to do so they would have to be designed carefully in a way that supports integration into the global economy and is consistent with national development strategies. Interim agreements have focused on reciprocal tariff removal and less restrictive rules of origin. To be fully effective, economic partnership agreements will have to address constraints to regional integration, including both tariff and non-tariff barriers; improve trade facilitation; and define appropriate most favored nation services liberalization. At the same time, African countries will need to reduce external tariff peak barriers on a most favored nation basis to ensure that when preferences for the European Union are implemented after transitional periods, they do not lead to substantial losses from trade diversion. This entails an ambitious agenda of policy reform that must be backed up by development assistance in the form of "aid for trade."Publication Why Trade Facilitation Matters to Africa(Washington, DC: World Bank, 2008-09)This paper reviews data and research on trade costs for Sub-Saharan African countries. It focuses on: border-related costs, transport costs, costs related to behind-the border issues, and the costs of compliance with rules of origin specific to preferential trade agreements. Trade costs are, on average, higher for African countries than for other developing countries. Using gravity-model estimates, the authors compute ad-valorem equivalents of improvements in trade indicators for a sample of African countries. The evidence suggests that the gains for African exporters from improving the trade logistics half-way to the level in South Africa is more important than a substantive cut in tariff barriers. As an example, improving logistics in Ethiopia half-way to the level in South Africa would be roughly equivalent to a 7.5 percent cut in tariffs faced by Ethiopian exporters.Publication Initial Conditions and Incentives for Arab Economic Integration : Can the European Community's Success be Emulated?(World Bank, Washington, DC, 2002-10)The authors compare the European Community's "trade fundamentals" prevailing in the 1960s with those applying in Arab countries today. The fundamentals differ significantly-Arab countries trade much less with each other than EC members did, and the importance of such trade in GDP varies greatly. This suggests that a viable Arab integration strategy must follow a path that differs from the preferential trade liberalization-led approach implemented by the European Community. An alternative is to complement long-standing attempts to liberalize merchandise trade with an effort that revolves around service sector reforms and liberalization. This may prove to be an effective mechanism to support reforms as, in principle, there is a major constituency in each Arab country that has an interest in improving the performance of services-the natural resource-based and manufacturing sectors. A key condition for such an approach to be feasible is that Arab cooperation helps overcome political economy resistance to national, unilateral action, or, generates direct gains from cooperation in specific policy areas. The EC experience suggests that a services-based integration strategy will be complex and must be carefully designed and sequenced. Given the importance of services-related trade and logistics transactions costs, a first step might focus on bringing such costs down through a concerted joint effort.Publication Regional Trade Agreements(2010-05-01)This paper reviews the theoretical and empirical literature on regionalism. The formation of regional trade agreements has been, by far, the most popular form of reciprocal trade liberalization in the past 15 years. The discriminatory character of these agreements has raised three main concerns: that trade diversion would be rampant, because special interest groups would induce governments to form the most distortionary agreements; that broader external trade liberalization would stall or reverse; and that multilateralism could be undermined. Theoretically, all of these concerns are legitimate, although there are also several theoretical arguments that oppose them. Empirically, neither widespread trade diversion nor stalled external liberalization has materialized, while the undermining of multilateralism has not been properly tested. There are also several aspects of regionalism that have received too little attention from researchers, but which are central to understanding its causes and consequences.Publication Pakistan : Reinvigorating the Trade Agenda(World Bank, Washington, DC, 2013-03)This paper reviews Pakistan's recent trade performance, its trade policy and trade costs. Different dimensions of trade performance growth and orientation, diversification and sophistication are assessed, complemented by an in-depth analysis of export dynamics in the period 2001-10 using firm-level data. An econometric exercise is also performed to identify the impact of tariffs, exchange rates, fixed costs to export, foreign demand, and preferential trade policy on the ability of firms to increase their exports. The analysis of Pakistan's trade policy includes tariffs, effective protection and trade restrictiveness estimates, as well as an assessment of the role of preferential trade agreements in the context of regional integration. Finally, the main characteristics of trade facilitation and logistics are analyzed, covering the capacity, performance, quality of services and degree of integration of the logistics system.

Publication Design Thinking for Social Innovation(2010-07)Designers have traditionally focused on enchancing the look and functionality of products.Publication Breaking the Conflict Trap : Civil War and Development Policy(Washington, DC: World Bank and Oxford University Press, 2003)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.Publication Governance Matters IV : Governance Indicators for 1996-2004(World Bank, Washington, DC, 2005-06)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.Publication Government Matters III : Governance Indicators for 1996-2002(World Bank, Washington, DC, 2003-08)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.Publication Governance Matters VIII : Aggregate and Individual Governance Indicators 1996–2008(2009-06-01)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.
