Abstract
Several studies have documented a positive and causal relationship product or process innovation -- and labor productivity. Given the links between labor productivity and wages, a likely implication of this positive relationship is that innovation is associated with higher wages of more productive firms. This paper explores the relationship between innovation and wages using Brazil's employer-employee census and a novel measure of innovation derived from the share of technical and scientific occupations of workers in the firm. The results show a robust and positive wage premium associated with innovative firms. The decomposition of this innovation-related wage premium suggests a series of important stylized facts: (i) the innovation wage premium is larger for manufacturing but also positive and significant for agriculture and services; (ii) it is larger for large firms, but also positive and significant for all firm size categories including micro firms; and (iii) it is larger for medium- and low-skill occupations, although this depends on the use of firm fixed effects. More importantly, the paper explores the causality between innovation and wages and finds empirical support for the ideas that “self-selection”—firms that innovate already pay higher wages before becoming innovators -- and increases in wages associated with starting innovation activity, which are persistent for three years after firms start innovating.

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 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 Global Poverty Revisited Using 2021 PPPs and New Data on Consumption(Washington, DC: World Bank, 2025-06-05)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.Publication From Patriarchy to Policy(Washington, DC: World Bank, 2025-05-29)Legal institutions play an important role in shaping gender equality in economic domains, from inheritance to labor markets. But where do gender equal laws come from? Using cross-country data on social norms and legal equality, this paper investigates the socio-cultural roots of gender inequity in the legal system and its implications for female labor force participation. To identify the impact of social norms, the analysis uses an empirical strategy that exploits pre-modern differences in ancestral patriarchal culture as an instrument for present-day gender norms. The findings show that ancestral patriarchal culture is a strong predictor of contemporary norms, and conservative social norms are associated with more gender inequality in the de jure legal framework, the de facto implementation of laws, and the labor market. The paper presents evidence for a political selection mechanism linking norms to laws: countries with more conservative norms elect political leaders who are more hostile to gender equality, who then pass less progressive legislation. The results highlight the cultural roots and political drivers of legalized gender inequality.Publication Global Socio-economic Resilience to Natural Disasters(Washington, DC: World Bank, 2025-05-22)Most disaster risk assessments use damages to physical assets as their central metric, often neglecting distributional impacts and the coping and recovery capacity of affected people. To address this shortcoming, the concepts of well-being losses and socio-economic resilience—the ability to experience asset losses without a decline in well-being—have been proposed. This paper uses microsimulations to produce a global estimate of well-being losses from, and socio-economic resilience to, natural disasters, covering 132 countries. On average, each $1 in disaster-related asset losses results in well-being losses equivalent to a $2 uniform national drop in consumption, with significant variation within and across countries. The poorest income quintile within each country incurs only 9% of national asset losses but accounts for 33% of well-being losses. Compared to high-income countries, low-income countries experience 67% greater well-being losses per dollar of asset losses and require 56% more time to recover. Socio-economic resilience is uncorrelated with exposure or vulnerability to natural hazards. However, a 10 percent increase in GDP per capita is associated with a 0.9 percentage point gain in resilience, but this benefit arises indirectly—such as through higher rate of formal employment, better financial inclusion, and broader social protection coverage—rather than from higher income itself. This paper assess ten policy options and finds that socio-economic and financial interventions (such as insurance and social protection) can effectively complement asset-focused measures (e.g., construction standards) and that interventions targeting low-income populations usually have higher returns in terms of avoided well-being losses per dollar invested.

Publication Firm-Level Technology Adoption in the State of Ceara in Brazil(World Bank, Washington, DC, 2021-03)This paper uses a novel approach to measure technology adoption at the firm level and applies it to a representative sample of firms in the state of Ceará in Brazil. The paper develops a new measure of technology adoption at the firm level, which identifies the purpose for which technologies are used and the intensive and extensive uses. The survey allows for establishing several new stylized facts for Ceará. First, most firms still rely on pre-digital technologies to perform general business functions, such as business administration, marketing, sales and payments, or quality control. Second, these technology gaps are larger in smaller firms, in the manufacturing sector, with large gaps when it comes to Industry 3.0 and digitalization, and especially large in Industry 4.0 technologies. The paper also presents some evidence that the main challenge to accelerate technology adoption is lack of firm capabilities. Despite the availability of technology extension services in the state, firms are still unaware of the availability of support and unwilling to upgrade technologies.Publication Firm-Level Technology Adoption in Vietnam(World Bank, Washington, DC, 2021-03)This paper describes the results of a new firm survey to measure technology use and adoption implemented prior to the COVID-19 pandemic in Vietnam. It analyzes the use and adoption of technology among Vietnamese firms and identifies some of the key barriers to adoption and diffusion. The analysis offers new and important stylized facts on firm-level use of technologies. First, although access to the internet is almost universal in Vietnam, firms had low digital readiness to face the COVID-19 pandemic; and the share of establishments with their own website, social media, and cloud computing is still small. Second, the use of Industry 4.0 technologies is incipient. Third, the technology gap with the use of frontier technologies in some general business functions, such as quality control, production planning, sales, and sourcing and procurement, is large. Fourth, the manufacturing sector faces the largest technological gap, larger than services and agricultural firms. The analysis of the main barriers and drivers to technology adoption and use shows the importance of good management quality for technology adoption, and that there is a technology premium associated with exporting activities. Finally, the analysis also shows that firms are largely unaware of the available public policy support for technology upgrading.Publication Businesses of the State in Brazil(Washington, DC: World Bank, 2025-03-07)Businesses of the state (BOS) have regained the public debate in midst of the COVID-19 pandemic, especially as a source of resilience to shocks and a mechanism for technology development and diffusion. However, little is known about the impacts on the economy. This paper uses a novel dataset that allows exploring the importance of BOS in Brazil, including registered state-owned or mixed enterprises and with indirect state participation in competitive sectors. The paper looks at their impact through two connected perspectives: employment and business dynamism. First, the analysis tests whether BOS pay a wage premium to their employees. Then, it estimates the impacts of privatization on workers’ outcomes and firms’ total employment. The findings indicate that BOS firms pay a substantial wage premium in Brazil and that privatization events lead to a significant decline in workers’ wages. Yet, the analysis does not find robust evidence that privatization results in a decline in total employment. The findings show that BOS tend to use more technical workers, a proxy for innovation, and are larger and grow faster in terms of employment than private companies. Finally, the paper analyzes what the presence of BOS means for the business dynamism of sectors. It finds that a higher presence of BOS in a given sector is negatively correlated with young firms’ participation and exit rates, and job destruction rates. Meanwhile, BOS participation is positively correlated with market concentration, but also job creation rates. The results suggest that BOS have significant impacts on markets, and that assessment of the state’s footprint needs to consider the effects of public investments in private companies, directly and indirectly.Publication Exporting and Technology Adoption in Brazil(World Bank, Washington, DC, 2023-06-15)There is limited evidence on the role of participating in international trade in the diffusion of technologies. This paper analyzes the impact of exporting on firms’ adoption of more sophisticated technologies, using a novel dataset, the Firm-level Adoption of Technology survey, which includes more than 1,500 firms in Brazil. The survey provides detailed information on the use of more than 300 technologies, combined with data from Brazil’s census of formal workers and export data from the Ministry of Trade. To address critical endogeneity concerns, the analysis applies difference-in-differences with multiple periods to examine the effects of entering export markets on technology adoption. The findings show that exporting has a positive effect on firms’ likelihood of adopting advanced technologies in business functions related to business administration, production planning, supply chain management, and quality control, which are important for managing tasks associated with export activities.Publication The Role of Technology in Reducing the Gender Gap in Productivity(Washington, DC: World Bank, 2024-05-16)This paper explores new firm-level data to examine the gender gap in technology adoption and the associated effect on firm performance. The data show a small difference in technology sophistication between firms managed by women and those managed by men, but there are larger differences in terms of labor productivity. Firms with female top managers are just as likely to adopt the most sophisticated technologies for general business functions that are common across all firms except for enterprise resource planning. However, firms managed by women adopt advanced technologies less frequently for sector-specific business functions. The study also finds that firms with higher technology sophistication tend to have higher productivity and the returns to the use of more sophisticated technologies are larger in businesses managed by women, which helps to narrow the productivity gap between firms managed by women and those managed by men.

Publication World Development Report 2011(World Bank, 2011)The 2011 World development report looks across disciplines and experiences drawn from around the world to offer some ideas and practical recommendations on how to move beyond conflict and fragility and secure development. The key messages are important for all countries-low, middle, and high income-as well as for regional and global institutions: first, institutional legitimacy is the key to stability. When state institutions do not adequately protect citizens, guard against corruption, or provide access to justice; when markets do not provide job opportunities; or when communities have lost social cohesion-the likelihood of violent conflict increases. Second, investing in citizen security, justice, and jobs is essential to reducing violence. But there are major structural gaps in our collective capabilities to support these areas. Third, confronting this challenge effectively means that institutions need to change. International agencies and partners from other countries must adapt procedures so they can respond with agility and speed, a longer-term perspective, and greater staying power. Fourth, need to adopt a layered approach. Some problems can be addressed at the country level, but others need to be addressed at a regional level, such as developing markets that integrate insecure areas and pooling resources for building capacity Fifth, in adopting these approaches, need to be aware that the global landscape is changing. Regional institutions and middle income countries are playing a larger role. This means should pay more attention to south-south and south-north exchanges, and to the recent transition experiences of middle income countries.Publication World Development Report 2006(Washington, DC, 2005)This year’s Word Development Report (WDR), the twenty-eighth, looks at the role of equity in the development process. It defines equity in terms of two basic principles. The first is equal opportunities: that a person’s chances in life should be determined by his or her talents and efforts, rather than by pre-determined circumstances such as race, gender, social or family background. The second principle is the avoidance of extreme deprivation in outcomes, particularly in health, education and consumption levels. This principle thus includes the objective of poverty reduction. The report’s main message is that, in the long run, the pursuit of equity and the pursuit of economic prosperity are complementary. In addition to detailed chapters exploring these and related issues, the Report contains selected data from the World Development Indicators 2005‹an appendix of economic and social data for over 200 countries. This Report offers practical insights for policymakers, executives, scholars, and all those with an interest in economic development.Publication The World Bank Group Beyond the Crisis(World Bank, Washington, DC, 2009-10-09)Robert B. Zoellick, President of the World Bank, addressed the following issues: seeds of crisis; the changing context; responsible globalization; the current role of the World Bank Group; the role of the World Bank Group in a new post-crisis World; and the reform agenda. He pointed to four aspects of Group’s future role: development finance; delivering knowledge products; the global public goods agenda (such as climate change and communicable diseases); and unforeseen future crises. Reform efforts include: 1) improving development effectiveness with a focus on results, decentralization, gender, investment lending reform, and human resources; 2) promoting accountability and good governance, and 3) increasing cost efficiency. He noted the completion of recent enhancements to the voice and representation of developing and transition countries in the Bank Group. Bretton Woods is being overhauled before our eyes.Publication Classroom Assessment to Support Foundational Literacy(Washington, DC: World Bank, 2025-03-21)This document focuses primarily on how classroom assessment activities can measure students’ literacy skills as they progress along a learning trajectory towards reading fluently and with comprehension by the end of primary school grades. The document addresses considerations regarding the design and implementation of early grade reading classroom assessment, provides examples of assessment activities from a variety of countries and contexts, and discusses the importance of incorporating classroom assessment practices into teacher training and professional development opportunities for teachers. The structure of the document is as follows. The first section presents definitions and addresses basic questions on classroom assessment. Section 2 covers the intersection between assessment and early grade reading by discussing how learning assessment can measure early grade reading skills following the reading learning trajectory. Section 3 compares some of the most common early grade literacy assessment tools with respect to the early grade reading skills and developmental phases. Section 4 of the document addresses teacher training considerations in developing, scoring, and using early grade reading assessment. Additional issues in assessing reading skills in the classroom and using assessment results to improve teaching and learning are reviewed in section 5. Throughout the document, country cases are presented to demonstrate how assessment activities can be implemented in the classroom in different contexts.Publication Remarks to the Annual Meetings 2020 Development Committee(World Bank, Washington, DC, 2020-10-16)David Malpass, President of the World Bank Group, announced that the Board approved a fast track approach to emergency health support programs that now covers 111 countries. Most projects are well advanced, with average disbursement upward of 40 percent. The goal is to take broad, fast action early. The operational framework presented back in June has positioned the Bank to help countries address immediate health threats and social and economic impacts and maintain our focus on long-term development. The Bank is making good progress toward the 15-month target of 160 billion dollars in surge financing. Much of it is for the poorest countries and will take the form of grants or low-rate, long-maturity loans. IFC, through the Global Health Platform, will be providing financing to vaccine manufacturers to foster expanded production of COVID-19 vaccines in both part 1 and 2 countries, providing production is reserved for emerging markets. The Development Committee holds a unique place in the international architecture. It is the only global forum in which the Governments of developed countries and the Governments of developing countries, creditor countries and borrower countries, come together to discuss development and the ‘net transfer of resources to developing countries.’ The current International Financial Architecture system is skewed in favor of the rich and creditor countries. It is important that all voices are heard, so Malpass urged the Ministers of developing countries to use their voice and speak their minds today. Malpass urged consideration of how we can build a new approach to debt restructuring that allows for a fair relationship and balance between creditors and debtors. This will be critical in restoring growth in developing countries; and helping reverse the inequality.
