    Product Market Regulation in Bulgaria : A Comparison with OECD Countries
    (World Bank, Washington, DC, 2007-11) Fay, Marianne; Ilieva, Stella
    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.

    Economic Structure, Productivity, and Infrastructure Quality in Southern Mexico
    (World Bank, Washington, DC, 2002-10) Deichmann, Uwe; Fay, Marianne; Koo, Jun; Lall, Somik V.
    There are large and sustained differences in the economic performance of sub-national regions in most countries. The authors examine the economic structure and productivity in Southern Mexico and compare it with the rest of the country. The authors use firm level data from Mexican manufacturing to test the relative importance of firm level characteristics (such as human capital and technology adoption) compared with external characteristics (such as infrastructure quality and regulatory environment) in explaining productivity differentials. The authors find that the economic structure of Southern Mexico is considerably different from the rest of the country, with the economic landscape dominated by micro enterprises and a relative specialization in low productivity activities. This, coupled with low skill levels and fewer skill upgrading opportunities, reduces the performance of Southern firms. Productivity differentials between Southern firms and others, however, only exist for micro enterprises. The econometric analysis shows that while employee training and technology adoption enhance productivity, access to markets by improving transport infrastructure that link urban areas also have important productivity effects.

    Funding and Financing Infrastructure: The Joint Use of Public and Private Finance
    (World Bank, Washington, DC, 2018-06) Martimort, David; Fay, Marianne; Straub, Stephane
    The paper addresses the issue of the feasible level of private finance in a contracting model of infrastructure finding and financing. It characterizes the structure of financial contracts, deriving the conditions under which both public and private finance coexist. A key feature is that access to outside finance and the regulatory decision on pricing and the amount of public subsidy, hence the extent of price recovery, are jointly determined. Mobilizing private finance requires a combination of price for the service and subsidy to the service provider that is large enough, exacerbating the fundamental tensions between financial viability through cost recovery and social inclusion. The paper then shows that the feasibility trade-off responds in non-trivial ways to changes in the economic and institutional environment likely to occur along the development path. While improvements along some of these dimensions, notably in the efficiency of bankruptcy procedures, appear to ease access to private finance, others, such as the cost of public funds, actually makes public finance more efficient. Using project data from the PPI database including information on the financial structure, the authors uncover an inverse U-shaped pattern in the share of private finance, peaking for countries in the upper-middle income range, which echoes their theoretical findings.

    Rising Incomes and Inequality of Access to Infrastructure among Latin American Households
    (World Bank, Washington, DC, 2017-02) Straub, Stephane; Fay, Marianne
    This paper documents access to services and ownership of infrastructure-related durables in the water, energy, telecom, and transport areas, based on harmonized household survey data covering 1.6 million households in 14 Latin American countries during 1992 to 2012. The paper provides a systematic disaggregation of access and ownership rates at different levels of income and over time, and econometrically derives the country infrastructure premium, a measure of how much a household benefits from simply being located in a given country. The results show extensive inequality of access, within countries across the income distribution, but also across countries for households at similar levels of income. For water and electricity, for example, up to two-thirds of the variability in individual percentile access to infrastructure services and consumption of related assets can be explained by country residence only. In addition, few country fundamentals appear to be significant in explaining this variability, pointing to policy differences as an important determinant. The paper derives the income elasticity of infrastructure access for the full set of indicators, and uses these to estimate the time that would be needed to close the remaining gap for households at different levels of the income distribution under a "business as usual" hypothesis. Under that scenario, universal access appears to be decades away for many countries in the region. The last part discusses the policy challenges, arguing that in a context in which public budgets face strong constraints and significant increases in private investment are unlikely to be forthcoming, a large part of the solution lies in refocused investment strategies, better demand management, and improved public spending efficiency.

    Rethinking Infrastructure in Latin America and the Caribbean: Spending Better to Achieve More
    (World Bank, Washington, DC, 2017-04-06) Fay, Marianne; Andres, Luis Alberto; Staub, Stephane; Narloch, Ulf
    Latin America and the Caribbean does not have the infrastructure it needs, or deserves, given its income. Many argue that the solution is to spend more; by contrast, this report has one main message: Latin America can dramatically narrow its infrastructure service gap by spending efficiently on the right things.

    From Growth to Green Growth : A Framework
    (2011-11-01) Hallegatte, Stephane; Fay, Marianne
    Green growth is about making growth processes resource-efficient, cleaner and more resilient without necessarily slowing them. This paper aims at clarifying these concepts in an analytical framework and at proposing foundations for green growth. The green growth approach proposed here is based on (1) focusing on what needs to happen over the next 5-10 years before the world gets locked into patterns that would be prohibitively expensive and complex to modify and (2) reconciling the short and the long term, by offsetting short-term costs and maximizing synergies and economic co-benefits. This, in turn, increases the social and political acceptability of environmental policies. This framework identifies channels through which green policies can potentially contribute to economic growth. However, only detailed country- and context-specific analyses for each of these channels could reach firm conclusion regarding their actual impact on growth. Finally, the paper discusses the policies that can be implemented to capture these co-benefits and environmental benefits. Since green growth policies pursue a variety of goals, they are best served by a combination of instruments: price-based policies are important but are only one component in a policy tool-box that can also include norms and regulation, public production and direct investment, information creation and dissemination, education and moral suasion, or industrial and innovation policies.

    Decarbonizing Development: Three Steps to a Zero-Carbon Future
    (Washington, DC: World Bank, 2015-06) Fay, Marianne; Hallegatte, Stephane; Vogt-Schilb, Adrien; Rozenberg, Julie; Narloch, Ulf; Kerr, Tom
    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.

    Rethinking Infrastructure in Latin America and the Caribbean: Spending Better to Achieve More
    (World Bank, Washington, DC, 2017-07-18) Fay, Marianne; Andres, Luis Alberto; Straub, Stephane; Narloch, Ulf
    Latin America and the Caribbean (LAC) does not have the infrastructure it needs, or deserves, given its income. Many argue that the solution is to spend more; by contrast, this report has one main message: Latin America can dramatically narrow its infrastructure service gap by spending efficiently on the right things. This report asks three questions: what should LAC countries’ goals be? How can these goals be achieved as cost-effectively as possible? And who should pay to reach these goals? In doing so, we drop the ‘infrastructure gap’ notion, favoring an approach built on identifying the ‘service gap’. Benchmarking Latin America in this way reveals clear strengths and weaknesses. Access to water and electricity is good, with the potential for the region’s electricity sector to drive competitive advantage; by contrast, transport and sanitation should be key focus areas for further development. The report also identifies and analyses some of the emerging challenges for the region—climate change, increased demand and urbanization—that will put increasing pressure on infrastructure and policy makers alike. Improving the region’s infrastructure performance in the context of tight fiscal space will require spending better on well identified priorities. Unlike most infrastructure diagnostics, this report argues that much of what is needed lies outside the infrastructure sector – in the form of broader government issues—from competition policy, to budgeting rules that no longer solely focus on controlling cash expenditures. We also find that traditional recommendations continue to apply regarding independent, well-performing regulators and better corporate governance, and highlight the critical importance of cost recovery where feasible and desirable, as the basis for future commercial finance of infrastructure services. Latin America has the means and potential to do better; and it can do so by spending more efficiently on the right things.

    Infrastructure in Latin America and the Caribbean : Recent Developments and Key Challenges
    (Washington, DC: World Bank, 2007) Fay, Marianne
    This book reviews Latin America's experience with infrastructure reform over the last fifteen years. It argues that the region's infrastructure has suffered from public retrenchment and unrealistic expectations about private involvement. Poor infrastructure now hampers productivity, growth, and poverty reduction. Addressing this requires more and better spending, and acceptance that governments remain central to infrastructure provision and supervision, although the private sector still has an important role to play.

    Current Debates on Infrastructure Policy
    (World Bank, Washington, DC, 2007-11) Estache, Antonio; Fay, Marianne
    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).
