Abstract
Each institutional arrangement in a financial system has both advantages and disadvantages in mobilizing savings, allocating capital, diversifying risks, and processing information when facilitating financial transactions. Meanwhile, the factor endowment in an economy at each stage of its development determines the optimal industrial structure in the real sector, which in turn constitutes the main determinant of the size distribution and risk features of viable enterprises with implications for the appropriate institutional arrangement of financial services at that stage. Therefore, there is an endogenously determined optimal financial structure for the economy at each stage of development.

    The Macroeconomic Implications of Climate Change Impacts and Adaptation Options
    (Washington, DC: World Bank, 2025-05-29) Abalo, Kodzovi; Boehlert, Brent; Bui, Thanh; Burns, Andrew; Castillo, Diego; Chewpreecha, Unnada; Haider, Alexander; Hallegatte, Stephane; Jooste, Charl; McIsaac, Florent; Ruberl, Heather; Smet, Kim; Strzepek, Ken
    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.

    South Africa’s Fragmented Cities: The Unequal Burden of Labor Market Frictions
    (Washington, DC: World Bank, 2026-01-08) Baez, Javier E.; Kshirsagar, Varun
    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.

    The Evolution of Local Participatory Democracy in Nepal
    (Washington, DC: World Bank, 2025-11-05) Bhusal, Thaneshwar; Breen, Michael G; Rao, Vijayendra
    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.

    Institutional Capacity for Policy Implementation: An Analytical Framework
    (Washington, DC: World Bank, 2026-01-07) Kim, Galileu; Kumar, Tanu; Ramalho, Rita; Russell, Stuart
    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.

    Closing the Gender Gap in Entrepreneurship: Overcoming Challenges in Law and Practice for Female Entrepreneurs
    (Washington, DC: World Bank, 2026-01-07) Behr, Daniela M.; Xi, Yue
    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.

    Turkey - Improving Conditions for SME Growth Finance and Innovation
    (Washington, DC, 2011-08) World Bank
    Facilitating the growth of Small- and Medium-sized Enterprises (SMEs) is central to creating jobs for an underutilized and growing labor force in Turkey as SMEs account for 79 percent of jobs in Turkey. Creating jobs for Turkey's unemployed and for the rapidly growing labor force, though partly a social challenge, is an important economic opportunity. Turkish SME growth performance and productivity is currently poor, and these related challenges must be simultaneously addressed. First, Turkish SMEs grow slower than both large enterprises in Turkey and SMEs in comparator countries. Second, not only are SMEs in Turkey less productive than larger firms, but the gap across firm size is larger in Turkey than in other countries. Although growth and productivity may be affected by different aspects of the business environment, productivity is needed for firms to be competitive and thus be able to sustain growth in the long term. Therefore, growth and productivity must be simultaneously addressed to enable the sustainable creation of well paying jobs. The two main priorities for SMEs are: a) access to finance, and b) the ability to adopt and use technology and to innovate, and this report addresses these topics. The main constraint for the growth of SMEs is access to finance, and new microeconomic evidence shows that the development of medium term finance contributes significantly to SME performance in terms of employment, sales, and investment. Specific interventions in the form of credit guarantees and credit line financing of financial institutions dedicated to support SME financial products have been used to speed up the development of the SME medium term credit market, and they may continue to play a role.

    OECS Private Sector Financing : Ridging the Supply-Demand Gap
    (Washington, DC, 2007-11) World Bank
    The high levels of public debt and persistent fiscal deficits limit Organization of Eastern Caribbean States (OECS) governments' ability to pursue counter-cyclical fiscal policies during future economic downturns, leaving private investment as the key driver of future growth. This study on private sector financing in the OECS analyzes the issue of access to finance from three different angles: the demand side; the supply side; and the enabling environment. It is not possible to fully analyze problems of access to finance without a broad approach. Demand side, supply side and the enabling environment are jointly analyzed in this study to identify key measures that could be applied in order to improve the enabling environment, create better opportunities for business growth and innovation (diversification), and place financial sector institutions in a position to provide finance, especially to SMEs, in a sustainable way.

    SMEs for Job Creation in the Arab World
    (World Bank, Washington, DC, 2012) Nasr, Sahar; Pearce, Douglas
    The Arab Spring in the Middle East and North Africa (MENA) region has brought to the forefront key challenges: the need to create job opportunities, equal access, a level playing field, transparency and accountability, and a fair and competitive environment. Crony capitalism, the privileged access of certain elites to favorable legal and regulatory treatment, access to markets, and the coincidence of political and economic power, was a major concern contributing to the uprising. Many saw privilege and corruption as the source of unemployment and inequality, effectively raising barriers to entry and growth for the majority of entrepreneurs. At the same time, practices such as connected lending and preferential land allocations, contributed to poor performance of key institutions, underpinning the market economy. It is critical for the MENA countries to achieve the aspirations of their people and attain sustainable and inclusive development by expanding private-led employment and creating entrepreneurship opportunities. This report assesses the supply and demand of financial services to small and medium enterprises (SMEs) in the MENA region, as well as the regulatory, institutional and policy environment that determines the cost, risk, and scale of SME finance. Emerging and promising SME finance models for banks, investors, government and regulators are outlined. These could significantly improve the outreach, viability, risk management, and development impacts of SME finance in the MENA region. SMEs need access to longer term credit products and equity, in addition to working capital loans and trade finance. They also need payment and card services, deposit facilities, liquidity management, risk management tools and insurance. The principal role of the state is as an enabler and regulator, providing the financial infrastructure, and legal and policy frameworks that financial institutions need to be able to meet the range of SME financial needs profitably. All this will contribute to attaining a more sustainable and inclusive system that can play a more important role in economic growth, and the regions prosperity.

    Formal Versus Informal Finance : Evidence from China
    (World Bank, Washington, DC, 2008-01) Ayyagari, Meghana; Demirgüç-Kunt, Asli; Maksimovic, Vojislav
    China is often mentioned as a counterexample to the findings in the finance and growth literature since, despite the weaknesses in its banking system, it is one of the fastest growing economies in the world. The fast growth of Chinese private sector firms is taken as evidence that it is alternative financing and governance mechanisms that support China's growth. This paper takes a closer look at firm financing patterns and growth using a database of 2,400 Chinese firms. The authors find that a relatively small percentage of firms in the sample utilize formal bank finance with a much greater reliance on informal sources. However, the results suggest that despite its weaknesses, financing from the formal financial system is associated with faster firm growth, whereas fund raising from alternative channels is not. Using a selection model, the authors find no evidence that these results arise because of the selection of firms that have access to the formal financial system. Although firms report bank corruption, there is no evidence that it significantly affects the allocation of credit or the performance of firms that receive the credit. The findings suggest that the role of reputation and relationship based financing and governance mechanisms in financing the fastest growing firms in China is likely to be overestimated.

    Financial Sector Assessment : Kenya
    (Washington, DC, 2005-03) World Bank
    This Financial Sector Assessment (FSA) is based on the work of the joint International Monetary Fund (IMF)- World Bank missions that visited Kenya from July 15 to July 24,2003, and from September 30 to October 15, 2003, in the context of the Financial Sector Assessment Program (FSAP). The principal objective of the missions was to assist the Kenyan authorities in assessing the development needs and opportunities for the financial sector and identifying potential vulnerabilities of financial institutions and markets to macroeconomic shocks, as well as the risks to macroeconomic stability from weaknesses and shortcomings in the financial sector. In this context, Kenya's compliance with the Basel core principles for Effective Banking Supervision (BCP); International Organization of Securities Commissions (IOSCO) principles for securities regulation; and corporate insolvency and creditor rights issues was formally assessed. A separate mission to assess Anti-Money Laundering (AML) or Combating the Financing of Terrorism (CFT) took place in October and November 2003; the Report on Observance of Standards and Codes (ROSC) from that mission is included in the FSAP documentation.

    Governance Matters VIII : Aggregate and Individual Governance Indicators 1996–2008
    (2009-06-01) Kaufmann, Daniel; Kraay, Aart; Mastruzzi, Massimo
    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.

    Government Matters III : Governance Indicators for 1996-2002
    (World Bank, Washington, DC, 2003-08) Kaufmann, Daniel; Kraay, Aart; Mastruzzi, Massimo
    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.

    Breaking the Conflict Trap : Civil War and Development Policy
    (Washington, DC: World Bank and Oxford University Press, 2003) Collier, Paul; Elliott, V. L.; Hegre, Håvard; Hoeffler, Anke; Reynal-Querol, Marta; Sambanis, Nicholas
    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.

    Governance Matters IV : Governance Indicators for 1996-2004
    (World Bank, Washington, DC, 2005-06) Kaufmann, Daniel; Kraay, Aart; Mastruzzi, Massimo
    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.
