Product Market Regulation in Bulgaria : A Comparison with OECD Countries
(World Bank, Washington, DC, 2007-11)Less restrictive product market policies are crucial in promoting convergence to higher levels of GDP per capita. This paper benchmarks product market policies in Bulgaria to those of OECD countries by estimating OECD indicators of Product Market Regulation (PMR). The PMR indicators allow a comprehensive mapping of policies affecting competition in product markets. Comparison with OECD countries reveals that Bulgaria has made substantial progress towards less restrictive product market policies but also emphasizes a number of areas where further reform is needed. These include adoption of a regulatory process based on incentive-based rather than command-and-control approach, reduction of state interference in the decision of state-owned enterprises, further streamlining of business licensing procedures, and improvement in the communication of rules and procedures to affected parties. -

Product Market Regulation in Romania : A Comparison with OECD Countries
(World Bank, Washington, DC, 2007-11)Less restrictive product market policies are crucial in promoting convergence to higher levels of GDP per capita. This paper benchmarks product market policies in Romania to those of OECD countries by estimating OECD indicators of Product Market Regulation (PMR). The PMR indicators allow a comprehensive mapping of policies affecting competition in product markets. Comparison with OECD countries reveals that Romania's product market policies are less restrictive of competition than most direct comparators from the region and not far from the OECD average. Nonetheless, this achievement should be interpreted in light of the fact that PMR approach measures officially adopted policies. It does not capture implementation and enforcement, the area where future reform efforts should be directed if less restrictive policies are to have an effective impact on long-term growth prospects. -

Current Debates on Infrastructure Policy
(World Bank, Washington, DC, 2007-11)This paper provides an overview of the major current debates on infrastructure policy. It reviews the evidence on the macroeconomic significance of the sector in terms of growth and poverty alleviation. It also discusses the major institutional debates, including the relative comparative advantage of the public and the private sector in the various stages of infrastructure service delivery as well as the main options for changes in the role of government (i.e. regulation and decentralization). -

Green Industrial Policies : When and How
(World Bank, Washington, DC, 2013-10)Green industrial policies can be defined as industrial policies with an environmental goal -- or more precisely, as sector-targeted policies that affect the economic production structure with the aim of generating environmental benefits. This paper provides a framework to assess their desirability depending on the effectiveness and political acceptability of price instruments. The main messages are the following. (i) Greening growth processes to the extent and with the speed needed cannot be done without industrial policies, even if prices can be adjusted to reflect environmental objectives. (ii) "Sunrise" green industrial policies are needed because they support the development of critical new technologies and sectors, bring down costs, and allow for reduced emissions in the short term even in the absence of carbon pricing. (iii) "Sunset" green industrial policies and trade policies may be needed in conjunction with safety nets to make carbon pricing politically or socially acceptable. They can help mitigate the impact of a carbon price on competitiveness and unemployment and smooth the transition by helping industries adjust to the new conditions. (iv) Green or not, industrial policy requires carefully navigating the twin dangers of market and governance failure. The viability of supported technologies and sectors is difficult to assess through a market-test given their dependence on continued environmental policies or pricing -- such as a carbon price. Particular attention must be paid to avoid potential unintended negative effects, such as rebound effects (especially if prices are inappropriate), misallocation of capital, or capture and rent-seeking behaviors. -

Investing in infrastructure : What is Needed from 2000 to 2010?
(World Bank, Washington, DC, 2003-07)The authors estimate demand for infrastructure services over the first decade of the new millennium based on a model that relates demand for infrastructure with the structural change and growth in income the world is expected to undergo between now and 2010. It should be noted that predictions are based on estimated demand rather than on any absolute measure of "need" such as those developed in the Millenium Development Goals. The authors also provide estimates of associated investment and maintenance expenditures and predict total required resource flows to satisfy new demand while maintaining service for existing infrastructure. -

Achieving the Millennium Development Goals : The Role of Infrastructure
(World Bank, Washington, DC, 2003-11)The authors provide an empirical analysis of the determinants of three child-health outcomes related to the Millennium Development Goals: the infant mortality rate, the child mortality rate, and the prevalence of malnutrition. Using data from Demographic and Health Surveys, they go beyond traditional cross-country regressions by exploiting the variability in outcomes and explanatory variables observed within countries between asset quintiles. The authors show the relationships existing between the prevalence of diseases (diarrhea and malnutrition) and mortality. Their findings suggest that apart from traditional variables (income, assets, education, and direct health interventions), better access to basic infrastructure services has an important role in improving child health outcomes. Their analysis of interaction effects between interventions also suggests the importance of combining interventions to meet the Millennium Development Goals. -

Financing the Future : Infrastructure Needs in Latin America, 2000-05
(World Bank, Washington, DC, 2001-02)To assess five-year demand for infrastructure investment in Latin America and the Caribbean, and the private sector's role in meeting this demand, the author developed a model to predict future demand for infrastructure - defined as what consumers and producers would ask for, given their income and level of economic activity. Overall projections over the next five years: a) A doubling of telephone mainlines per capita. b) A steady increase in electricity generating capacity. c) Small increases in water and sanitation coverage. d) Steady expansion of road infrastructure, with rail transport becoming less important. Investments of $57 billion annually for 2000-05 (roughly 2.6 percent of Latin America's GDP) are expected to be absorbed largely by electricity ($22 billion), roads ($18 billion), and telecommunications ($ 6 billion). A surge in private finance of infrastructure in recent years (roughly $35 billion in 1998, excluding divestiture payments) has disproportionately favored telecommunications ($14 billion) and transport ($12 billion). Private investment exceeds predicted need for telecommunications (although the model did not include costs associated with the emergence of cellular phones), covers about half the demand for roads, and meets just a fraction of needs in power and water and sanitation - where there will be a shortfall in investments. Projections are likely to be on the low side because they cover new investments, not rehabilitation or maintenance. -

Climate Change and Poverty : An Analytical Framework
(World Bank Group, Washington, DC, 2014-11)Climate change and climate policies will affect poverty reduction efforts through direct and immediate impacts on the poor and by affecting factors that condition poverty reduction, such as economic growth. This paper explores this relation between climate change and policies and poverty outcomes by examining three questions: the (static) impact on poor people's livelihood and well-being; the impact on the risk for non-poor individuals to fall into poverty; and the impact on the ability of poor people to escape poverty. The paper proposes four channels that determine household consumption and through which households may escape or fall into poverty (prices, assets, productivity, and opportunities). It then discusses whether and how these channels are affected by climate change and climate policies, focusing on the exposure, vulnerability, and ability to adapt of the poor (and those vulnerable to poverty). It reviews the existing literature and offers three major conclusions. First, climate change is likely to represent a major obstacle to a sustained eradication of poverty. Second, climate policies are compatible with poverty reduction provided that (i) poverty concerns are carefully taken into account in their design and (ii) they are accompanied by the appropriate set of social policies. Third, climate change does not modify how poverty policies should be designed, but it creates greater needs and more urgency. The scale issue is explained by the fact that climate will cause more frequent and more severe shocks; the urgency, by the need to exploit the window of opportunity given to us before climate impacts are likely to substantially increase. -

Urbanization without Growth : A Not-So-Uncommon Phenomenon
(World Bank, Washington, DC, 2000-08)To find out why African countries' experience with urbanization and sustained growth appeared to differ from that of other countries, the authors investigated the determinants of urbanization across countries over 40 years. Rather than studying individuals' decisions to migrate, they relied on macroeconomic data and cross-country comparisons. A central hypothesis of their study: that individuals move (with varying degrees of ease) in response to economic incentives and opportunities. If location incentives are distorted, so is growth. The authors find that urbanization levels are closely correlated with levels of income. But urbanization continues even during periods of negative growth, carried by its own momentum, largely a function of the level of urbanization. From that viewpoint, Africa's urbanization without growth is not a puzzle. Factors other than income that help predict differences in levels of urbanization across countries include: a) income structure; b) education; c) rural-urban wage differentials; d) ethnic tensions; and e) civil disturbances. In addition, the relationship between economic incentives and urbanization is weaker in countries with fewer civil or political liberties. Factors other than initial urbanization level that help explain the speed of urbanization include: 1) The sector from which income growth is derived; 2) ethnic tensions; 3) civil disturbances and democracy (these two slow the pace of urbanization if all else is constant); 4) rural-urban wage differentials, whether they represent an urban bias or simply lower productivity in agriculture relative to other sectors. The weak relationship that this study shows between urbanization and traditionally accepted migration factors suggests that in Africa economists are overlooking part of the urbanization story. The fact that the informal sector appears to provide a significant source of income for urban migrants, coupled with the overlap between rural and urban activities, may shed light on the nature of urbanization in Africa. -

Decarbonizing Development: Three Steps to a Zero-Carbon Future
(Washington, DC: World Bank, 2015-06)The science is unequivocal: stabilizing climate change implies bringing net carbon emissions to zero. And this must be done by 2100 if we are to keep climate change anywhere near the 2 C. degree warming that world leaders have set as the maximum acceptable limit. Decarbonizing Development looks at what it would take to decarbonize the world economy by 2100 in a way that is compatible with countries’ broader development goals. It argues that the following are needed: Act early with an eye on the end-goal; Go beyond prices with a policy package that triggers changes in investment patterns, technologies and behaviors; Mind the political economy and smooth the transition for those who stand to be most affected.
