The Container Port Performance Index 2020 to 2024: Trends and Lessons Learned
No full textThe Container Port Performance Index (CPPI) provides a global benchmark of how container ports perform in handling vessel calls. Developed jointly by the World Bank and S&P Global Market Intelligence, it measures the time ships spend in port and relates this to the number of containers moved during that time. This approach makes the CPPI a unique diagnostic tool that can highlight patterns in port operations and shed light on global and regional supply chain dynamics. Now in its fifth edition, the CPPI report covers the period from 2020 to 2024. It builds on a well-established methodology to generate scores for more than 400 container ports worldwide. Over time, the CPPI has become a trusted reference point for policymakers, industry stakeholders, and researchers who seek to understand how ports adapt to shocks, recover from disruptions, and identify opportunities for investments, reform and modernization. A major innovation in this edition is the introduction of multi-year trend analysis. Rather than presenting annual snapshots, the report now tracks how CPPI scores have changed across five years. This longitudinal perspective reveals shifts in port performance, showing where scores have risen, fallen, or remained stable. By linking these movements to external factors, the CPPI offers insights into how global and regional supply chains evolve under pressure. The results clearly mirror the crises that have shaken global trade. During the COVID-19 pandemic, CPPI scores in different regions declined sharply as congestion, equipment shortages, and delays overwhelmed many ports. By 2023, global averages rebounded in parallel with easing freight markets and reduced congestion. Yet 2024 brought new challenges: the Red Sea crisis disrupted major trade lanes, while climate-related constraints at the Panama Canal added further stress. These shocks were reflected in lower global and several regional average scores, underscoring the vulnerability of maritime transport to geopolitical and environmental events. The CPPI is not about comparing one port against another, but about understanding changes in performance over time. Ports that improved their scores often did so by reducing time at anchor, optimizing berth operations, investing in digital tools, and strengthening coordination across logistics partners. The evidence confirms that improvements are possible across ports of all sizes, and that rising scores are linked to deliberate actions to minimize time in port relative to containers moved. By consolidating five years of results, this edition transforms the CPPI into a long-term reference point. It shows how global crises have affected shipping, how different regions have adapted, and what lessons can be drawn for future resilience. The World Bank and S&P Global Market Intelligence remain committed to maintaining the CPPI as a global public good, providing transparency, comparability, and practical insights to support more reliable and sustainable maritime supply chains
Nickel, Steel and Cars: Export Ban and Domestic Value-Added in Indonesia
No full textNickel is essential for producing iron and steel. Endowed with the world's largest reserve, Indonesia banned nickel exports in 2014 to promote industrialization. This paper studies the impacts of the export ban on downstream steel-using industries. A three-sector model shows that, while the export ban could raise the domestic value-added ratio (DVAR) in exports, the entry of smaller, inefficient firms led to aggregate efficiency losses downstream. Firm-level evidence confirms higher DVAR, smaller firm size, and larger entrant shares in downstream industries post the export ban. A field mission validated these results, while noting the continued heavy reliance on imported steel
The Impact of Technology on Migration to the United States from Central America and the Dominican Republic
No full textLabor markets in Central America and the Dominican Republic face limited direct impacts from technological advancements compared to developed countries. However, substantial migration flows to high-income countries, particularly the United States, mean that the impacts of technological change do not stop at country borders. During the past 50 years, recent migrants from both Central America and the Dominican Republic and other countries, like US nonmigrant workers, have shifted out of production jobs requiring (automatable) routine manual and cognitive skills. Although recent non–Central America and the Dominican Republic migrants and US nonmigrants transitioned to higher-skilled work intensive in nonroutine cognitive and interpersonal tasks (for example, management), recent migrants from Central America and the Dominican Republic shifted toward jobs intensive in nonroutine manual tasks (for example, construction) and, to a lesser extent, in nonroutine interpersonal tasks (for example, serving). In essence, migrants from other middle- and high-income countries have benefited from the same technology-skill complementarity as nonmigrant US workers, whereas migrants from Central America and the Dominican Republic seem to have filled the lower-skilled jobs created alongside technological advancement. The low-skill bias of migrants from Central America and the Dominican Republic suggests greater vulnerability to disruption from artificial intelligence and mobile robotics, but less from language models like ChatGPT. Closer analysis of US robot adoption between 2000 and 2019 shows no effect on total migration flows from Central America and the Dominican Republic but impacts on high-skilled flows between 2010 and 2019. US robot adoption in the early 2000s improved labor market outcomes for high-skilled migrants from Central America and the Dominican Republic but in low-skilled, nonroutine occupations. Between 2010 and 2019, the demand expansion effect that seems to explain this improvement weakened. Robot adoption led to less demand for high-educated migrants from Central America and the Dominican Republic during this latter decade
An Apple a Day: The Impact of Healthier School Meals on Children in Jordan
No full textPoor nutritional choices and unhealthy behaviors are considered responsible for the rise in childhood overweight and obesity and may reinforce each other, creating a vicious cycle. This paper studies a primary school intervention designed to break the cycle early in life by replacing date bars with calorie-equivalent meals lower in sugar and fat. Leveraging the randomized pilot of a menu change in Jordan’s national school feeding program, the study shows that children consuming the alternative meals spend 8 percent less money to buy processed snacks, are more physically active (0.1 standard deviation), and go to school one extra day per year
Beyond Green Jobs: Advancing Metrics and Modeling Approaches for a Changing Labor Market
No full textThe concept of “green jobs” has received widespread attention in academic, policy, and public discourse, reflecting the growing emphasis on sustainability and the transition to a low-carbon economy. However, defining and measuring green jobs remains analytically challenging and highly sensitive to methodological choices. This paper systematically examines how alternative classification criteria and data aggregation methods produce markedly divergent estimates of green jobs. It shows that the share of occupations identified as green ranges from 0 to 74 percent depending on the methodology, raising concerns about the comparability and usefulness of green job estimates in practice. Moving beyond the traditional green jobs framing, the paper proposes a more pragmatic and flexible framework that focuses on identifying jobs-in-demand and jobs-at-risk under specific transition scenarios. This approach allows for application across different country contexts and different transition scenarios and can also incorporate other structural labor market shocks, such as technological change or demographic shifts. The paper undertakes a literature review of quantitative methodologies to analyze labor reallocation in the context of given labor market shocks, highlighting the trade-offs between backward-looking (historical transition matrices) and forward-looking (task- and skill-based) approaches. It also discusses key challenges in integrating labor market dynamics into macroeconomic models and takes stock of recent efforts in hybrid modeling that combines macroeconomic frameworks with micro-level labor market insights. The paper concludes by outlining priority areas for future research and methodological development

PENGARUH KECEPATAN SHAKER DALAM ADSORPSI ZAT WARNA (METHYL ORANGE) MENGGUNAKAN CANGKANG TELUR AYAM
No full textThe batik industry in Samarinda has been continuously developing from year to year. According to 2024 data, the batik industry generates wastewater amounting to 2,678,400 liters annually. This wastewater contains hazardous compounds, one of which is Methyl Orange, an aromatic azo compound characterized by a double bond (-N=N) and its carcinogenic properties. Therefore, it is necessary to treat the wastewater to eliminate the azo dye completely. One approach that can be applied is adsorption, due to its simplicity and widespread use in treating various types of pollutants. This study aims to investigate the effect of the presence or absence of a shaker on the effectiveness of eggshells as an adsorbent in reducing the dye concentration. The methods used in this research include adsorbent preparation, the adsorption process, and UV-Vis spectrophotometric analysis. Adsorption was carried out with variations in shaker speed at 120, 160, 200, 240, and 280 RPM. The results showed the highest adsorption efficiency of 57.80% at an adsorbent mass of 11 grams, pH 1, for 60 minutes, with a shaker speed of 120 RPM
