Abstract
This paper studies the consequences of a U.S. cabotage law for Puerto Rico (PR). Data on ship arrivals in PR show that the fleet of U.S. vessels that call there lacks capacity for carrying non-containerized freight. Empirical estimation using trade data shows that PR’s imports of sea-shipped final products are biased against U.S. mainland sources. This bias is strongest for heavy products and products not typically shipped in containers. Among upstream products, a strong bias against imports of sea-shipped products applies to all sources. Estimated tariff-equivalent costs among final products imply static annual welfare losses of 1.1 percent of household consumption ($203 per person). The same tariff-equivalent cost estimates imply that the law raises the cost of investment in PR by 3.0 percent. The observed bias against sea-shipped inputs in PR’s imports may result from long-run industry location decisions that have been influenced by the law's presence.

Publication Geopolitics and the World Trading System(Washington, DC: World Bank, 2024-12-23)Until the beginning of this century, the GATT/WTO system worked. Economic research provided a compelling explanation. It showed that if governments maximize the well-being of their own countries broadly defined, GATT/WTO principles would facilitate mutually beneficial cooperation over their trade policy choices. Now heightened geopolitical rivalry seems to have undermined the WTO. A simple transposition of the previous rationalization suggests that geopolitics and trade cooperation are not compatible. The paper shows that this is only true if rivalry eclipses any consideration of own-country well-being. In all other circumstances, there are gains from trade cooperation even with geopolitics. Furthermore, the WTO’s relevance is in question only if it adheres too rigidly to its existing rules and norms. Through measured adaptation to the geopolitical imperative, the WTO can continue to thrive as a forum for multilateral trade cooperation in the age of geopolitics.Publication Chinese Imports and Industrialization in Africa(Washington, DC: World Bank, 2025-05-12)The rise of China in the global economy has been linked with negative impacts on employment across many high- and middle-income countries. However, evidence for African countries is limited. This paper investigates the causal relationship between Chinese imports and manufacturing employment in Ethiopia. Imports may harm domestic firms through a revenue effect (lower market shares) or benefit them, indirectly if competition spurs innovation or directly through access to better quality or cheaper inputs. The analysis shows that a one unit increase in import penetration leads to a 15.2 percent increase in industry employment. The inputs effect is disentangled from the other two effects by decomposing total Chinese imports by their end-use category using input-output tables. The evidence shows that imported intermediate inputs are driving the employment gains. The findings are consistent with the idea that employment gains are a result of productivity gains and increases in capacity utilization. These employment gains appear to benefit large firms and labor-intensive industries disproportionately.Publication VAT Exemptions, Embedded Tax, and Unintended Consequences(Washington, DC: World Bank, 2025-05-15)The value-added tax (VAT) has proved to be a highly effective tool at raising revenue in developed and developing countries alike. However, the effective operation of the VAT breaks down in the presence of exemptions. Unlike zero rates, exemptions deny input tax credits, thereby increasing production costs and resulting in VAT being embedded within the prices of goods and services. This paper develops a VAT model based on input-output table and household budget survey data for 29 European countries to examine the effects of VAT exemptions on final prices and to assess the merits of their use. Simulation results show that exemptions suffer from the same targeting problems as reduced VAT rates, but, in addition, they are non-transparent and have unpredictable and counterproductive indirect effects. These effects are in addition to the well-known distortionary impact of exemptions on production decisions, and their creation of incentives to self-supply. The paper concludes that the use of exemptions should be limited to addressing pragmatic concerns, such as the disproportionate compliance costs of small businesses and the practical difficulty in taxing margin-based financial services.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 Economic Consequences of Trade and Global Value Chain Integration(World Bank, Washington, DC, 2025-04-04)This paper introduces a new approach to measuring Global Value Chains (GVC), crucial for informed policy-making. It features a tripartite classification (backward, forward, and two-sided) covering trade and production data. The findings indicate that traditional trade-based GVC metrics significantly underestimate global GVC activity, especially in sectors like services and upstream manufacturing, and overstate risks in early trade liberalization stages. Additionally, conventional backward-forward classifications over-estimate backward linkages. The paper further applies these measures empirically to assess how GVC participation mediates the impact of demand shocks on domestic output, highlighting both the exposure and stabilizing potential of GVC integration. These new measures are comprehensively available on the World Bank’s WITS Platform, providing a key resource for GVC analysis.

Publication Trade in International Maritime Services : How Much Does Policy Matter?(Washington, DC: World Bank, 2002-01)Maritime transport costs significantly impede international trade. This article examines why these costs are so high in some countries and quantifies the importance of two explanations: restrictive trade policies and private anticompetitive practices. It finds that both matter, but the latter have a greater impact. Trade liberalization and the breakup of private carrier agreements would lead to an average of one-third lower liner transport prices and to cost savings of up to US dollar 3 billion on goods carried to the United States alone. The policy implications are clear: there is a need not only for further liberalization of government policy but also for strengthened international disciplines on restrictive business practices. The authors propose an approach to developing such disciplines in the current round of services negotiations at the World Trade Organization (WTO).Publication Trade in International Maritime Services : How Much Does Policy Matter?(World Bank, Washington, DC, 2001-01)Maritime transport costs significantly impede international trade. The authors examine why these costs are so high in some countries, and, quantify the importance of two explanations: restrictive trade policies, and private anti-competitive practices. Both matter, they find, but private anti-competitive practices have the greater impact. Trade liberalization, and the breakup of private carrier agreements, would lead to a reduction in average liner transport prices of a third, and cost savings of up to $ 3 billion on goods carried to the United States alone. The policy implications are clear: not only should government policy be further liberalized, but there should be stronger international disciplines on restrictive business practices. The authors propose developing such disciplines in the current round of services negotiations at the World Trade Organization.Publication Port and Maritime Transport Challenges in West and Central Africa(World Bank, Washington, DC, 2007-05)This Working Paper presents the current trends in maritime transport and port sectors in West and Central Africa (WCA), and proposes several policy recommendations to improve maritime transport and port efficiency in order to enhance economic growth. West and Central African economies, which depend on maritime transport for an overwhelming proportion of their trade, rely on efficient maritime transport and port sectors to be competitive on world markets. This paper was prepared for the Sub-Saharan Africa Transport Policy Program (SSATP), in the overall context of the World Bank's efforts for trade facilitation in Sub- Saharan Africa2 as a follow-up to the 1997 Second Cotonou meeting of West and Central Africa (WCA) Ministers.Publication Understanding the Operations of Freight Forwarders(World Bank, Washington, DC, 2015-06)Freight forwarders play a key role in moving goods across international borders. They arrange transport, oversee customs clearance on behalf of their clients, and more generally troubleshoot issues that arise while goods are in transit. This paper reports the results from a survey of 153 freight forwarding firms in Serbia. Respondents report on firm characteristics, operational choices, and conditions at the border posts and terminals where imported goods are cleared for release. One key purpose of the study is to investigate operational trade-offs between time and cost that arise when import shipments are in transit. In three of four hypotheticals, respondents suggest that money savings dominate time savings. Responses regarding real operational decisions such as route choices reinforce this finding. Respondents also reported penalty rates for late delivery of import shipments as well as the value of a typical import shipment. From these responses, it is estimated that the contracted value of one additional (unexpected) day of delivery time in Serbia appears to be approximately 1 percent of the value of the underlying shipment.Publication Maritime Transport Costs and Port Efficiency(World Bank, Washington, DC, 2002-02)Recent literature has emphasized the importance of transport costs and infrastructure in explaining trade, access to markets, and increases in per capita income. For most Latin American countries transport costs are a greater barrier to U.S. markets than import tariffs. The authors investigate the determinants of the costs of shipping to the United States using a large database (more than 300,000 observations a year) on shipments of products at the six-digit level of the Harmonized System of classification from different ports around the world. They find that distance and containerization matter. They find that the efficiency of ports is also important. Improving the efficiency of a port from the 25th to the 75th percentile reduces shipping costs by 12 percent. (On average, having bad ports is equivalent to being 60 percent farther away from markets.) Inefficient ports also increase handling costs, which are part of shipping costs. Finally, the authors try to explain variations in port efficiency. They find that the variations are linked to excessive regulation, the prevalence of organized crime, and the general condition of the country's infrastructure.

Publication Remarks at the United Nations Biodiversity Conference(World Bank, Washington, DC, 2021-10-12)World Bank Group President David Malpass discussed biodiversity and climate change being closely interlinked, with terrestrial and marine ecosystems serving as critically important carbon sinks. At the same time climate change acts as a direct driver of biodiversity and ecosystem services loss. The World Bank has financed biodiversity conservation around the world, including over 116 million hectares of Marine and Coastal Protected Areas, 10 million hectares of Terrestrial Protected Areas, and over 300 protected habitats, biological buffer zones and reserves. The COVID pandemic, biodiversity loss, climate change are all reminders of how connected we are. The recovery from this pandemic is an opportunity to put in place more effective policies, institutions, and resources to address biodiversity loss.Publication South Asia Development Update, April 2024: Jobs for Resilience(Washington, DC: World Bank, 2024-04-02)South Asia is expected to continue to be the fastest-growing emerging market and developing economy (EMDE) region over the next two years. This is largely thanks to robust growth in India, but growth is also expected to pick up in most other South Asian economies. However, growth in the near-term is more reliant on the public sector than elsewhere, whereas private investment, in particular, continues to be weak. Efforts to rein in elevated debt, borrowing costs, and fiscal deficits may eventually weigh on growth and limit governments' ability to respond to increasingly frequent climate shocks. Yet, the provision of public goods is among the most effective strategies for climate adaptation. This is especially the case for households and farms, which tend to rely on shifting their efforts to non-agricultural jobs. These strategies are less effective forms of climate adaptation, in part because opportunities to move out of agriculture are limited by the region’s below-average employment ratios in the non-agricultural sector and for women. Because employment growth is falling short of working-age population growth, the region fails to fully capitalize on its demographic dividend. Vibrant, competitive firms are key to unlocking the demographic dividend, robust private investment, and workers’ ability to move out of agriculture. A range of policies could spur firm growth, including improved business climates and institutions, the removal of financial sector restrictions, and greater openness to trade and capital flows.Publication Education, Social Norms, and the Marriage Penalty(Washington, DC: World Bank, 2024-10-16)A growing literature attributes gender inequality in labor market outcomes in part to the reduction in female labor supply after childbirth, the child penalty. However, if social norms constrain married women’s activities outside the home, then marriage can independently reduce employment, even in the absence childbearing. Given the correlation in timing between childbirth and marriage, conventional estimates of child penalties will conflate these two effects. The paper studies the marriage penalty in South Asia, a context featuring conservative gender norms and low female labor force participation. The study introduces a split-sample, pseudo-panel approach that allows for the separation of marriage and child penalties even in the absence of individual-level panel data. Marriage reduces women’s labor force participation in South Asia by 12 percentage points, whereas the marginal penalty of childbearing is small. Consistent with the central roles of both opportunity costs and social norms, the marriage penalty is smaller among cohorts with higher education and less conservative gender attitudes.Publication Economic Recovery(World Bank, Washington, DC, 2021-04-06)World Bank Group President David Malpass spoke about the world facing major challenges, including COVID, climate change, rising poverty and inequality and growing fragility and violence in many countries. He highlighted vaccines, working closely with Gavi, WHO, and UNICEF, the World Bank has conducted over one hundred capacity assessments, many even more before vaccines were available. The World Bank Group worked to achieve a debt service suspension initiative and increased transparency in debt contracts at developing countries. The World Bank Group is finalizing a new climate change action plan, which includes a big step up in financing, building on their record climate financing over the past two years. He noted big challenges to bring all together to achieve GRID: green, resilient, and inclusive development. Janet Yellen, U.S. Secretary of the Treasury, mentioned focusing on vulnerable people during the pandemic. Kristalina Georgieva, Managing Director of the International Monetary Fund, focused on giving everyone a fair shot during a sustainable recovery. All three commented on the importance of tackling climate change.Publication Media and Messages for Nutrition and Health(World Bank, Washington, DC, 2020-06)The Lao People’s Democratic Republic (Lao PDR) has experienced rapid and significant economic growth over the past decade. However, poor nutritional outcomes remain a concern. Rates of childhood undernutrition are particularly high in remote, rural, and upland areas. Media have the potential to play an important role in shaping health and nutrition–related behaviors and practices as well as in promoting sociocultural and economic development that might contribute to improved nutritional outcomes. This report presents the results of a media audit (MA) that was conducted to inform the development and production of mass media advocacy and communication strategies and materials with a focus on maternal and child health and nutrition that would reach the most people from the poorest communities in northern Lao PDR. Making more people aware of useful information, essential services and products and influencing them to use these effectively is the ultimate goal of mass media campaigns, and the MA measures the potential effectiveness of media efforts to reach this goal. The effectiveness of communication channels to deliver health and nutrition messages to target beneficiaries to ensure maximum reach and uptake can be viewed in terms of preferences, satisfaction, and trust. Overall, the four most accessed media channels for receiving information among communities in the study areas were village announcements, mobile phones, television, and out-of-home (OOH) media. Of the accessed media channels, the top three most preferred channels were village announcements (40 percent), television (26 percent), and mobile phones (19 percent). In terms of trust, village announcements were the most trusted source of information (64 percent), followed by mobile phones (14 percent) and television (11 percent). Hence of all the media channels, village announcements are the most preferred, have the most satisfied users, and are the most trusted source of information in study communities from four provinces in Lao PDR with some of the highest burden of childhood undernutrition.
