Abstract
The authors explore how Koreas financial structure affects the volatility of asset prices. Documented empirical evidence of the relationship between financial structure and financial crisis, sheds light on the relationship between asset price volatility - extreme variations in price - and financial structure. And the volatility of financial and non-financial asset prices provides an indirect link between an economys financial structure and the likelihood of financial crisis. Using time-series data on a se of indicators measuring financial structure, the authors examine how Koreas financial structure affects the volatility of the real effective exchange rate, the money market rate, government bond yields, and stock prices. They find: 1) There is a stable long-term relationship between financial structure and volatility in the real effective exchange rate, the money market rate, stock prices, and the yield on government housing bonds. 2) Financial structure affects asset price variables asymmetrically. Some variables volatility increases, and others diminish, suggesting that monetary policies should target different asset markets to achieve different goals. If the goal of the monetary authority is to stabilize the money market rate, for example, intervening in the banking sector is more efficient than intervening in other financial sub-sectors. 3) The higher volatility of stock prices reflects the thin stock market in Korea. 4) The stability of the yield on government housing bonds reflects the Korean governments policy of stabilizing the nations housing supply by isolating the housing market from the impact of Koreas financial structure. 5) Restrictions on foreigners ownership of domestic stock in Korea during the period analyzed, and the fact that most capital flows through commercial banks, affect the exchange rate, which is determined (at least in the short run) by capital flows in the foreign exchange market.

Publication The Economic Value of Weather Forecasts: A Quantitative Systematic Literature Review(Washington, DC: World Bank, 2025-09-10)This study systematically reviews the literature that quantifies the economic benefits of weather observations and forecasts in four weather-dependent economic sectors: agriculture, energy, transport, and disaster-risk management. The review covers 175 peer-reviewed journal articles and 15 policy reports. Findings show that the literature is concentrated in high-income countries and most studies use theoretical models, followed by observational and then experimental research designs. Forecast horizons studied, meteorological variables and services, and monetization techniques vary markedly by sector. Estimated benefits even within specific subsectors span several orders of magnitude and broad uncertainty ranges. An econometric meta-analysis suggests that theoretical studies and studies in richer countries tend to report significantly larger values. Barriers that hinder value realization are identified on both the provider and user sides, with inadequate relevance, weak dissemination, and limited ability to act recurring across sectors. Policy reports rely heavily on back-of-the-envelope or recursive benefit-transfer estimates, rather than on the methods and results of the peer-reviewed literature, revealing a science-to-policy gap. These findings suggest substantial socioeconomic potential of hydrometeorological services around the world, but also knowledge gaps that require more valuation studies focusing on low- and middle-income countries, addressing provider- and user-side barriers and employing rigorous empirical valuation methods to complement and validate theoretical models.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 Labor Demand in the Age of Generative AI: Early Evidence from the U.S. Job Posting Data(Washington, DC: World Bank, 2025-11-18)This paper examines the causal impact of generative artificial intelligence on U.S. labor demand using online job posting data. Exploiting ChatGPT’s release in November 2022 as an exogenous shock, the paper applies difference-in-differences and event study designs to estimate the job displacement effects of generative artificial intelligence. The identification strategy compares labor demand for occupations with high versus low artificial intelligence substitution vulnerability following ChatGPT’s launch, conditioning on similar generative artificial intelligence exposure levels to isolate substitution effects from complementary uses. The analysis uses 285 million job postings collected by Lightcast from the first quarter of 2018 to the second quarter of 2025Q2. The findings show that the number of postings for occupations with above-median artificial intelligence substitution scores fell by an average of 12 percent relative to those with below-median scores. The effect increased from 6 percent in the first year after the launch to 18 percent by the third year. Losses were particularly acute for entry-level positions that require neither advanced degrees (18 percent) nor extensive experience (20 percent), as well as those in administrative support (40 percent) and professional services (30 percent). Although generative artificial intelligence generates new occupations and enhances productivity, which may increase labor demand, early evidence suggests that some occupations may be less likely to be complemented by generative artificial intelligence than others.Publication The Lasting Effects of Working while in School(Washington, DC: World Bank, 2025-08-18)This paper provides the first experimental evidence on the long-term effects of work-study programs, leveraging a randomized lottery design from a national program in Uruguay. Participation leads to a persistent 11 percent increase in formal labor earnings, observable seven years after the program. Effects are stronger for youth who participate during pivotal educational transitions and are larger for vulnerable youth and men, while remaining positive for women and non-vulnerable youth. The program is highly cost-effective, with average impacts exceeding those of job training programs and comparable to early childhood investments.Publication It’s Not (Just) the Tariffs: Rethinking Non-Tariff Measures in a Fragmented Global Economy(Washington, DC: World Bank, 2025-10-22)As tariffs have declined, non-tariff measures (NTMs) have become central to trade policy, especially in high-income countries and regulated sectors like food and green technologies. Although NTMs may serve legitimate goals, they could also sort countries and firms into or out of markets based on compliance capacity and differences in product mix. Documenting recent advances in the estimation of ad valorem equivalents (AVEs), this paper uncovers new patterns of use and exposure of NTMs. High-income countries rely more heavily on NTMs relative to tariffs, while low- and middle-income countries face steeper AVEs on their exports. Firm-level evidence shows that NTMs disproportionately affect smaller firms, leading to market exit and concentration. Poorly designed NTMs can harm productivity and welfare, while coordinated, capacity-aware use can deliver inclusive outcomes. Policy design, transparency, and diagnostics must evolve to reflect the growing role—and risks—of NTMs in a fragmented global trade landscape.

Publication Republic of Korea Financial Sector Assessment Program : Detailed Assessment of Observance - Basel Core Principles folr Effective Banking Supervision(World Bank, Washington, DC, 2014-09)This assessment of the current state of the implementation of the Basel core principles for effective banking supervision (BCP) in the Republic of Korea has been completed as part of a financial sector assessment program (FSAP) update undertaken by the international monetary fund (IMF) and the World Bank (WB) during 2013. It reflects the regulatory and supervisory framework in place as of the date of the completion of the assessment. An assessment of the effectiveness of banking supervision requires a review of the legal framework, and detailed examination of the policies and practices of the institution(s) responsible for banking regulation and supervision. In line with the BCP methodology, the assessment focused on the financial services commission - financial supervisory authority (FSC-FSS). This FSAP provides introduction; information and methodology used for assessment; institutional and macroeconomic setting and market structure - overview; preconditions for effective banking supervision; summary compliance with the Basel core principles; and detailed assessment.Publication Growth Volatility in Paraguay : Sources, Effects, and Options(Washington, DC, 2014-06-05)The purpose of the current study is to contribute to a deeper understanding of growth volatility in Paraguay and to provide an input into the discussion on how to better manage it. In particular, the study will ask three questions: i) what are the sources of volatility in Paraguay? ii) How does growth volatility, in particular that arising from the strong dependence on the agricultural sector, impact the rest of the economy? iii) What are optimal policies for managing the types of volatility observed in Paraguay?Publication Is Fiscal Policy the Answer? A Developing Country Perspective(Washington, DC: World Bank, 2013)Fiscal policy is an important instrument for maintaining and improving living standards. Such living standards can be viewed as an outcome of the interaction between the opportunities offered by society and the readiness and ability of each person to exploit them. Under certain circumstances, public finance can make an important contribution to the creation of opportunities within a given society by raising resources from the private sector through taxation or borrowing (domestic and external) and allocating those resources effectively and equitably in the form of public spending, including through public goods and transfers. The first chapters in this volume sketch out a framework that policy makers can use in adopting a more cohesive or integrated approach to the short- and long-term dimensions of fiscal policy. Here the traditional threefold rationale for fiscal policy proposed by Musgrave-stabilization, resource allocation, and distribution-continues to be useful. Other chapters in this volume take up some of the critical institutional challenges in implementing fiscal policy for longer-term growth and development. These chapters also look at the tools and approaches being developed to address these challenges. Improving the quality of public investment management is a particular priority in view of the recent evidence that as little as half of all public investment expenditure translates into productive capital stock. The last chapter in this volume is a case study of fiscal responses to the great recession in low-income Sub-Saharan Africa, looking at stabilization and the longer-run growth, as well as distributional aspects of such responses. The growing depth of domestic financial markets in many African countries rather unexpectedly is turning out to be a critical source of financing for fiscal policy responses.Publication Bank Risk and Deposit Insurance(2002-01)Arguing that a relatively high cost of deposit insurance indicates that a bank takes excessive risks, this article estimates the cost of deposit insurance for a large sample of banks in 14 economies to assess the relationship between the risk-taking behavior of banks and their corporate governance structure. The results suggest that banks with concentrated ownership tend to take the greatest risks, and those with dispersed ownership engage in a relatively low level of risk taking. Moreover, as a proxy for bank risk, the cost of deposit insurance has some power in predicting bank distressPublication Korea : Financial Sector Assessment(World Bank, Washington, DC, 2003-06)Since the financial crisis in 1997-98, Korea has made major progress in financial, and corporate sector reform - the supervisory and regulatory regime for the financial sector has been substantially strengthened, and recent reforms helped achieve a high degree of observance of international standards, and codes. Moreover, significant consolidation in the banking system took place, with banks becoming more profit oriented, and their operations streamlined. The impressive macroeconomic performance led to strong real growth, low inflation, and growing official foreign reserves, facilitating the improvement of measured financial sector soundness. However, important reform measures were delayed, e.g., addressing issues in the areas of insurance and securities, adopting the insolvency framework, and in the completion of corporate restructuring, reforms crucial to prevent an economic downturn. Despite progress in prudential supervision, concerns remain on the regulator's ability to supervise risks, and, information and monitoring of connected lending and cross ownership in the financial crisis, also remain issues of concern. Key recommendations suggest that steps should be taken to reassure markets that the independence of the regulator is important; that measures to strengthen provisioning for household lending are welcome; that a full examination of the Korea Development Bank should be conducted, including a review of the derivatives-related accounting systems, complemented by a targeted external audit of the bank; a continued pension reform is urgent given the rapidly aging population; and, particularly worrisome is the seemingly inadequate supervision of the problems arising from non-bank deposits taking institutions' face soundness, where tighter supervision of securities is warranted. Similarly, corporate governance and disclosure need further steps, aligning accounting and auditing reforms with evolving internal best practices.

Publication Argentina Country Climate and Development Report(World Bank, Washington, DC, 2022-11)The Argentina Country Climate and Development Report (CCDR) explores opportunities and identifies trade-offs for aligning Argentina’s growth and poverty reduction policies with its commitments on, and its ability to withstand, climate change. It assesses how the country can: reduce its vulnerability to climate shocks through targeted public and private investments and adequation of social protection. The report also shows how Argentina can seize the benefits of a global decarbonization path to sustain a more robust economic growth through further development of Argentina’s potential for renewable energy, energy efficiency actions, the lithium value chain, as well as climate-smart agriculture (and land use) options. Given Argentina’s context, this CCDR focuses on win-win policies and investments, which have large co-benefits or can contribute to raising the country’s growth while helping to adapt the economy, also considering how human capital actions can accompany a just transition.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 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 Dominican Republic Poverty Assessment 2023(Washington, DC: World Bank, 2023-11-08)In recent decades, economic growth in the Dominican Republic (DR) has been steady. However, growth has not occurred in such a way as to make the benefits widely and evenly available. In fact, although the DR economy grew faster than that of other LAC countries before the Covid-19 pandemic, its poverty rates and social outcomes remain broadly similar to them. This report seeks to explain this conundrum, as well as to expand the knowledge base to improve the effectiveness of ongoing poverty reduction policies in the DR. The Poverty Assessment draws primarily on new analytical work conducted in the DR, structured around four background notes on: (i) trends in monetary poverty and inequality, as well as the key drivers of those changes; (ii) nonmonetary poverty and its spatial dimensions; (iii) social assistance programs and their role in mitigating poverty; and (iv) climate change and its interaction with poverty. By helping to reduce the evidence gap in each of these areas, our analysis hopes to inform government policies and the national dialogue on poverty reduction. In addition, the note integrates existing analytical work and evidence produced inside and outside the Bank, including from its operations in the country.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.
