Abstract
This paper proposes a measure of the extent to which a financial sector is connected to the real economy. The Measure of Connectedness is a measure of the composition of assets, namely the share of credit to the non-financial sectors over the total credit market instruments. The aggregate Measure of Connectedness for the United States declines by about 27 percent in the period 1952-2009. The authors suggest that this increase in disconnectedness between the financial sector and the real economy may have dampened the sensitivity of the real economy to monetary shocks. They present a stylized model that illustrates how interbank trading can reduce the sensitivity of lending to the entrepreneur's net worth, thereby dampening the credit channel transmission of monetary policy. The Measure of Connectedness is interacted with both a structural vector autoregressive model and a factor-augmented vector autoregressive model for the United States economy. The analysis establishes that the impulse responses to monetary policy shocks are dampened as the level of connection declines.

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 South Africa’s Fragmented Cities: The Unequal Burden of Labor Market Frictions(Washington, DC: World Bank, 2026-01-08)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.Publication The Evolution of Local Participatory Democracy in Nepal(Washington, DC: World Bank, 2025-11-05)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.Publication Institutional Capacity for Policy Implementation: An Analytical Framework(Washington, DC: World Bank, 2026-01-07)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.Publication Closing the Gender Gap in Entrepreneurship: Overcoming Challenges in Law and Practice for Female Entrepreneurs(Washington, DC: World Bank, 2026-01-07)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.

Publication The U.S. Subprime Mortgage Crisis(World Bank, Washington, DC, 2008)The subprime mortgage crisis ranks among the most serious economic events affecting the United States since the great depression of the 1930s. This study analyzes key issues raised by the crisis at three levels: (i) issues directly and specifically relating to subprime mortgage lending; (ii) issues relating to the securitization of subprime mortgages; and (iii) issues affecting financial markets and institutions. These issues are fundamental to risk bearing, sharing, and transfer in financial markets and institutions around the world. Many of the issues raised by the U.S. subprime crisis also apply to high-risk loan markets in developing countries. The framework applied in the paper analyzes subprime mortgage lending as a major financial market innovation. Although conditions were conducive for subprime lending to arise as a financial innovation, financial innovations are necessarily risky undertakings, all the more so when they create new classes of risky loans and securities. The lessons learned from the crisis can thus be usefully applied to issues of the growth and development of emerging economies, as well as pointing the way to the design of new and efficient policies for subprime lending in the developed economies.Publication The Unexpected Global Financial Crisis : Researching Its Root Cause(2012-01-01)The world is currently still struggling with the aftermath of the worst economic crisis since the Great Depression. Following a description of the eruption, evolution and consequences of the global crisis, this paper reviews alternative hypotheses for the causes of the global financial crisis as well as their empirical evidence. The paper refutes the frequently voiced view that the global crisis was caused by global imbalances that reflected economic policies of East Asian countries. Instead, it argues that global imbalances were the result of excess demand in the United States, resulting from both the public debt in the United States arising from the Afghanistan and Iraqi wars and tax cuts and the overconsumption by households supported by the wealth effect from the housing bubble in the United States. The housing bubble itself was the outcome of the Federal Reserve's low interest rate policy in the aftermath of the burst of the "dot-com" bubble in 2001, the lack of appropriate financial regulation, and housing policies aimed at expanding the mortgage market to low-income borrowers. It was possible to maintain the large trade deficits of the United States for such a long period of time because of the dollar's reserve currency status. When the housing bubble in the United States burst, the global crisis ensued. The paper also analyzes why China's trade surplus increased significantly in general and with the United States in particular in recent years, and argues that this increase was caused by both the relocation of the labor-intensive tradable sector of East Asian economies to China and high corporate saving rates in China as a result of its dual-track approach to reform.Publication Financial Sector Assessment : Barbados(World Bank, Washington, DC, 2014-03)The financial system faces a weak economic outlook and a deteriorating fiscal position posing substantial macroeconomic risks. As a result, sovereign risk has increased while the fixed exchange rate further limits policy options. The financial system has sizeable sovereign risk exposures and non-performing loans are rising although high capital and liquidity buffers in combination with strong parent entities mitigate risks. Credit unions appear more vulnerable. Since the 2008 financial sector assessment program (FSAP), the regulatory and supervisory framework has improved across all sectors. Consolidated risk-based supervision was introduced in the banking sector along with a formalization of supervisory methodologies. The government has committed a major adjustment package aimed at stabilizing international reserves and consolidating the fiscal position. Even if planned policies are successful, Barbados will continue to face challenging growth prospects, driven by weakened tourism markets, including Canada, the United Kingdom, and the United States; increased competition from other offshore jurisdictions; and appreciation of the real effective exchange rate.Publication Malaysia : Bond Market Development(World Bank, Washington, DC, 2013-01)This paper pertains to the bond market development in Malaysia, and provides an overview of the market scenario in the country. Malaysia has been successful in developing the capital markets, particularly bond markets, in the recent past. Now, it faces the challenge of how to improve broader access and efficiency of the bond market. A high degree of investor concentration, dominated by government pension funds, plays a significant role in impeding the growth of higher-yield bond market. The role of the government in stimulating the growth of the bond markets should be now shifted toward encouraging more diversity. In order to promote risk diversity, significant measures should be taken to increase competition on the demand side. Another important challenge for the bond markets going forward is improving transparency to make them more attractive to a broader constituency. To improve liquidity and transparency, the authorities should encourage the establishment of open, independent electronic platforms that integrate price search, negotiation, and trading of bonds. It is felt that while Malaysia has seen success in the bond markets, there is scope for further improvement.Publication Enabling Conditions for Second Pillars of Pension Systems(2009-04-01)This note adds to the existing literature by examining the enabling conditions for the creation of mandatory funded pension funds, and identifying additional factors that are important to consider in the early stages of the reform. The note stresses the importance of some factors that had already been identified in previous literature but not fully observed by reforming countries, including the strong and lasting commitment of the authorities with the reform, the fiscal commitment with the reform, and some basic financial infrastructure. The analysis is also extended to analyze the role of supervision in the early stages of the reform and the role of the government in fostering the development of the domestic capital market.

Publication Monetary Policy Strategies for Latin America(World Bank, Washington, DC, 2001-10)The authors examine possible monetary policy strategies for Latin America that may help lock in the gains the region attained in the fight against inflation in the 1990s. Instead of focusing the debate about the conduct of monetary policy on whether the nominal exchange rate should be fixed or flexible, the focus should be on whether the monetary policy regime appropriately constrains discretion in monetary policymaking. Three basic frameworks deserve serious discussion as possible long-run strategies for monetary policy in Latin America. The authors examine the advantages and disadvantages of a hard exchange-rate peg, monetary targeting, and inflation targeting, in light of monetary policy's recent track record in several Latin American countries, looking for clues about which of the strategies might be best suited to economies in the region. The answer: It depends on the country's institutional environment. Some countries appear not to have the institutions to constrain monetary policy if discretion is allowed. In those countries, there is a strong argument for hard pegs, including full dollarization, that allow little or no discretion to monetary authorities. In countries such as Chile, which can constrain discretion, inflation targeting is likely to produce a monetary policy that keeps inflation low yet appropriately copes with domestic and foreign shocks. Monetary targeting as a strategy for Latin America is not viable because of the likely instability of the relationship between inflation and monetary aggregates, of which there is ample international evidence. No monetary strategy can solve the basic problems that have existed in Latin American economies for a long time. The authors welcome the recent move in Latin American countries toward inflation targeting, but say no policy will succeed unless government policies also create the right institutional environment.Publication Digital Africa(Washington, DC: World Bank, 2023-03-13)All African countries need better and more jobs for their growing populations. "Digital Africa: Technological Transformation for Jobs" shows that broader use of productivity-enhancing, digital technologies by enterprises and households is imperative to generate such jobs, including for lower-skilled people. At the same time, it can support not only countries’ short-term objective of postpandemic economic recovery but also their vision of economic transformation with more inclusive growth. These outcomes are not automatic, however. Mobile internet availability has increased throughout the continent in recent years, but Africa’s uptake gap is the highest in the world. Areas with at least 3G mobile internet service now cover 84 percent of Africa’s population, but only 22 percent uses such services. And the average African business lags in the use of smartphones and computers as well as more sophisticated digital technologies that catalyze further productivity gains. Two issues explain the usage gap: affordability of these new technologies and willingness to use them. For the 40 percent of Africans below the extreme poverty line, mobile data plans alone would cost one-third of their incomes—in addition to the price of access devices, apps, and electricity. Data plans for small- and medium-size businesses are also more expensive than in other regions. Moreover, shortcomings in the quality of internet services—and in the supply of attractive, skills-appropriate apps that promote entrepreneurship and raise earnings—dampen people’s willingness to use them. For those countries already using these technologies, the development payoffs are significant. New empirical studies for this report add to the rapidly growing evidence that mobile internet availability directly raises enterprise productivity, increases jobs, and reduces poverty throughout Africa. To realize these and other benefits more widely, Africa’s countries must implement complementary and mutually reinforcing policies to strengthen both consumers’ ability to pay and willingness to use digital technologies. These interventions must prioritize productive use to generate large numbers of inclusive jobs in a region poised to benefit from a massive, youthful workforce—one projected to become the world’s largest by the end of this century.Publication On the Effects of Enforcement on Illegal Markets(Published by Oxford University Press on behalf of the World Bank, 2017-06-01)This paper studies the effects of enforcement on illegal behavior in the context of a large aerial spraying program designed to curb coca cultivation in Colombia. In 2006, the Colombian government pledged not to spray a 10 km band around the frontier with Ecuador due to diplomatic frictions arising from the possibly negative collateral effects of this policy on the Ecuadorian side of the border. We exploit this variation to estimate the effect of spraying on coca cultivation by regression discontinuity around the 10 km threshold and by conditional differences in differences. Our results suggest that spraying one additional hectare reduces coca cultivation by 0.022 to 0.03 hectares; these effects are too small to make aerial spraying a cost-effective policy for reducing cocaine production in Colombia.Publication China’s Export Growth and the China Safeguard : Threats to the World Trading System?(2010-05-01)Is there evidence from China's pre-WTO accession period that newly imposed U.S. or EU import restrictions deflect Chinese exports to third markets? The authors examine this question by drawing on a newly constructed data set of U.S. and EU product-level import restrictions on Chinese trade imposed between 1992 and 2001 and estimate their impact on Chinese exports to 38 alternative markets. There is no systematic evidence that the import restrictions imposed during this period resulted in Chinese exports surging to such alternate destinations. To the contrary, there is weak evidence of a chilling effect on China's exports to third markets.Publication Road Capacity, Domestic Trade and Regional Outcomes(World Bank, Washington, DC, 2021-09)What is the impact on intranational trade and regional economic outcomes when the quality and lane capacity of an existing paved road network is expanded significantly? This paper investigates this question for the case of Turkey, which undertook a large-scale public investment in roads during the 2000s. Using spatially disaggregated data on road upgrades and domestic transactions, the paper estimates a large positive impact of reduced travel times on trade as well as local manufacturing employment and wages. A quantitative exercise using a workhorse model of spatial equilibrium implies heterogeneous effects across locations, with aggregate real income gains reaching 2–3 percent in the long run. Reductions in travel times increased the local employment-to-population ratio but had no effect on local population. The model is extended by endogenizing the labor supply decision to capture this finding. The model-implied elasticity of employment rates to travel time reductions captures about one-third of the empirical elasticity.
