    Paralleltitel: Estache, Antonio Bidders' entry and auctioneer's rejection
    Kurzfassung: "Limited competition has been a serious concern in infrastructure procurement. Importantly, however, there are normally a number of potential bidders initially showing interest in proposed projects. This paper focuses on tackling the question why these initially interested bidders fade out. An empirical problem is that no bids of fading-out firms are observable. They could decide not to enter the process at the beginning of the tendering or may be technically disqualified at any point in the selection process. This paper applies the double selection model to procurement data from road development projects in developing countries and examines why competition ends up restricted. It shows that bidders are self-selective and auctioneers also tend to limit participation depending on the size of contracts. Therefore, limited competition would likely lead to high infrastructure procurement costs. "--World Bank web site

    Paralleltitel: Estache, Antonio Auctions with endogenous participation and quality thresholds
    Kurzfassung: "Infrastructure projects are often technically complicated and highly customized. Therefore, procurement competition tends to be limited. Competition is the single most important factor toward auction efficiency and anti-corruption. However, the degree of competition realized is closely related to bidders' entry decision and the auctioneer's decision on how to assess technical attributes in the bid evaluation process. This paper estimates the interactive effects among quality, entry, and competition. With data on procurement auctions for electricity projects in developing countries, it is found that large electricity works are by nature costly and can attract only a few participants. The limited competition would raise government procurement costs. In addition, high technical requirements are likely to be imposed for these large-scale projects, which will in turn add extra costs for the better quality of works and further limit bidder participation. The evidence suggests that quality is of particular importance in large infrastructure projects and auctioneers cannot easily substitute price for quality. "--World Bank web site

    Schlagwort(e): Government purchasing ; Infrastructure (Economics) ; Sanitation ; Water-supply ; Government purchasing ; Infrastructure (Economics) ; Sanitation ; Water-supply
    Kurzfassung: "Competition in public procurement auctions in the water supply and sanitation sector is largely limited. This is partly because of high technical complexity and partly because of auction design flaws. The division of lot contracts is an important policy choice for auctioneers to achieve efficiency. In general, there is a tradeoff between competition in auctions and size of contracts. Larger works could benefit from economies of scale and scope, but large contracts might undermine competition. Using data on public procurement auctions for water and sewage projects in developing countries, this paper shows that bidder entry is crucially endogenous, especially because it is determined by the auctioneer's bundling and unbundling strategy. If water treatment plant and distribution network works are bundled in a single lot package, competition would be significantly reduced, and this adverse entry effect would in turn raise the public procurement costs of infrastructure. There is no evidence of positive scope economies in the bidder cost structure. It is important to account for the underlying cost structure for designing efficient auction mechanisms.

    Paralleltitel: Estache, Antonio Ppi partnerships versus ppi divorces in developing countries (or are we switching from pppi to ppdi?)
    Schlagwort(e): Infrastructure (Economics) ; Privatization ; Public-private sector cooperation ; Infrastructure (Economics) ; Privatization ; Public-private sector cooperation
    Kurzfassung: "Thirty years ago, in 1974, Chile launched the first large-scale privatization in a developing country. About 15 years later, Argentina provided a new model of global infrastructure management. Since then a variety of public-private partnerships in infrastructure have been adopted throughout the developing and transition world. These experiences add up to a large and heterogeneous enough sample of experiences from which some fairly robust conclusions on who benefited from the reforms and who did not. Because many of these experiences are also turning sour and the 'privatization' fad of the 1990s seems to be turning into an 'antiprivatization' fad, it seems important to separate facts from emotions. Estache argues that the wide differences in interpretations of the facts can be explained by wide differences in the assessment criteria used by analysts, including the definition of the baseline data chosen to assess the incremental effect of reforms. It is also driven by the sectors, the regions, and probably most important, the actors on which the analysis tends to focus. Once all these factors have been considered, a relatively fair and quantitative assessment of the prospects of the public-private relationship in infrastructure is possible. This paper--a product of the Office of the Vice President, Infrastructure Network--is part of a larger effort in the network to stimulate a debate on the effectiveness of infrastructure reforms"--World Bank web site

    Paralleltitel: Benitez, Daniel A How concentrated are global infrastructure markets?
    Schlagwort(e): Globalization ; Infrastructure (Economics) ; Globalization ; Infrastructure (Economics)
    Kurzfassung: "In infrastructure, the possibility of a positive relationship between operators' profitability and the degree of concentration is a major political issue in view of the wide diversity of feelings about the potential role of the private sector. This is particularly important because of (1) the large residual degree of monopolies, (2) the protection they are granted through exclusivity clauses built in service delivery contracts, and (3) the widespread sense that the same operators tend to be present in most of the privatized operations. The main purpose of this paper is to provide a first set of quantitative assessments of the degree of concentration in infrastructure at the global and the regional levels. Concentration issues were identified in only about 20 percent of the cases studied, and a presumption of concentration was found in another 30 percent of the cases. Benitez and Estache find no correlation between the degree of concentration and the degree of reform adopted by a region or a sector. In more general terms, they find no scope for simple encompassing regional or sectoral statements because issues are region- and sector-specific. The authors conclude by arguing that there are a few cases and regions in which it would make sense for a supranational competition or regulation agency to ensure that the interests of the users are protected more effectively against the risks of collusion and other types of anti-competitive behaviors local regulators would not be equipped to address. This paper--a product of the Office of the Vice President, Infrastructure Network--is part of a larger effort in the network to document the state of the sector"--World Bank web site

    Schlagwort(e): Infrastructure (Economics) ; Infrastructure (Economics)
    Kurzfassung: "Estache, Laffont, and Zhang develop a model to analyze the effects of asymmetric information on optimal universal service policy in the public utilities of developing countries. Optimal universal service policy is implemented using two regulatory instruments pricing and network investment. Under discriminatory pricing, asymmetric information leads to a higher price and smaller network in the rural area than under full information. Under uniform pricing, the price is lower but the network is even smaller. In addition, under both pricing regimes, not only the firm but also taxpayers have incentives to collude with the regulator.

    Paralleltitel: Estache, Antonio Are returns to private infrastructure in developing countries consistent with risks since the Asian crisis?
    Schlagwort(e): Business cycles ; Infrastructure (Economics) ; Business cycles ; Infrastructure (Economics)
    Kurzfassung: "Estache and Pinglo present a basic assessment of the financial performance of infrastructure service operators in developing countries. They rely on a new database of 120 companies put together to track the evolution of the cost of capital, the cost of equity, and the return of equity for electricity, water and sanitation, railways, and port operators in 32 developing countries distributed evenly across low-income, low-middle-income, and upper-middle-income countries. The authors show that between 1998 and 2002, the average cost of capital in developing countries varied from less than 11 percent to over 15 percent across regions and sectors, while the cost of equity varied from around 13 percent to over 22 percent. Low-middle-income countries have recovered relatively well from the East Asia crisis, while low-income and upper-middle-income countries have seen their situation deteriorate since the crisis. At the regional level, the main story is that East Asia is recovering quite well from its crisis, and that the financial performance of the operators in Africa and Latin America has deteriorated. Eastern Europe and South Asia are doing relatively better but show a large volatility of returns over time and within sectors. At the sector level, the railways and the energy sectors have seen their performance deteriorate significantly over the period, while the water and port sectors have done relatively better. In all sectors and regions, the average return to equity has been lower than the cost of equity since the Asian crisis.

    Paralleltitel: Estache, Antonio Have consumers benefited from the reforms in the electricity distribution sector in Latin America?
    Schlagwort(e): Infrastructure (Economics) ; Infrastructure (Economics)
    Kurzfassung: "Estache and Rossi bring new empirical evidence on the impact of the choice of ownership and regulatory regime on firms' productivity and prices paid by consumers. They collect the evidence from a sample of electricity distribution companies in Latin America. The authors rely on estimations of labor and operation and maintenance (O&M) input requirement functions using alternative econometric approaches. Their main conclusions are: Private firms perform better (approximately 30 percent) than public firms. The regulatory regimes matter, so that price-cap regulated firms do better than rate-of-return regulated firms, and firms regulated under hybrid regimes have intermediate performance. Private firms operating under rate of return are at most as efficient as public firms. There is no clear pattern of differences in electricity prices according to the regulatory regime. Final prices fell in general but the drop did not match the productivity gains, implying that the operators and the state share some of the gains in the form of rents and higher tax revenue, respectively.
