Reviving project appraisal at the World Bank
Get PDFThe authors focus on two broad questions: 1) what is the proper role for project evaluation in today's world, where countries have reduced major economic distortions and are reconsidering the role of the state? and 2) besides project evaluation, how else can economic analysis ensure high-quality projects? The authors argue for a shift in the emphasis of project evaluation away from a concern with precise rate of return calculations to a broader examination of the rationale for public provision. In this context, three areas critical for proper project appraisal are the counterfactual private sector supply response, the fiscal impact, and the fungibility of lending. (1) Counterfactual private sector supply response. Any type of cost-benefit analysis - be it in the public or the private sector - requires the project evaluator to specify the counterfactual: what wouldthe world have looked like in the absence of the project? Since World Bank projects are public sector projects, the relevant counterfactual involves assessing what the private sector would have otherwise provided, and the relevant magnitude for evaluation purposes is the net contribution of the public project. Failure to consider explicitly the private sector counterfactual during evaluation biases the lending mix of the Bank away from projects with strong public good characteristics toward projects with private good characteristics. (2) Fiscal impact. Applying the private sector couterfactual would lead the Bank to undertake projects with a reasonable case for public intervention, such as basic infrastructure, primary education, and rural health. These projects typically share the characteristics that costs are borne by the public sector while benefits are enjoyed by the private sector. But in the absence of nondistortionary, lump sum taxes, there is likely to be a positive marginal cost of taxation and a premium on public income. Since the Bank has not used such a premium and treats public costs and private benefits equally, it has systematically overestimated the net benefits of these projects. (3) Fungibility of lending. Project-specific appraisal can at best assess only the rate of return and the acceptability of the project being appraised. This limitation is problematic because the project might have been undertaken even without Bank financing. If that is the case, the Bank is actually financing some other project - one not subject to appraisal by the Bank - that would not have been in the investment program without Bank financing. This problem arises because financial resources are fungible to some extent. One way to alleviate this concern is to conduct public expenditure reviews before embarking on the appraisal and financing of specific projects. Furthermore, financing a portion of the government's sectoral investment program may be more effective than project-specific lending.Decentralization,Health Economics&Finance,Public Health Promotion,Poverty Monitoring&Analysis,Environmental Economics&Policies,Health Economics&Finance,Environmental Economics&Policies,Poverty Monitoring&Analysis,Economic Theory&Research,Health Monitoring&Evaluation
Equity and growth in developing countries : old and new perspectives on the policy issues
Get PDFThe"stylized fact"that distribution must get worse with economic growth in poor countries before it can get better turns out not to be a fact at all. Growth's effects on inequality can go either way and are contingent on several other factors. The authors found no sign in the new cross-country data they assembled that growth has any systematic impact on inequality. Possibly measurement errors confound the true relationship, but they think it more likely that the relationship between growth and distribution is not as simple as some theories have held. Since distribution does not worsen, growth reduces absolute poverty. Indeed, absolute poverty measures typically respond quite elastically to growth, and the benefits are certainly not confined to those near typical poverty lines. Of course, one cannot say that growth always benefits the poor or that none of the poor lose from pro-growth policy reform. Only aggregate effects are studied. But for 17 of the 20 countries for which they assemble quite good data (from at least two surveys since the mid-1980s), the mean and the proportion of people living below $1 a day moved in opposite directions. The gains to poor people from a distribution-neutral growth process will tend to be lower, the higher the extent of initial inequality. A smaller share of total income must imply a smaller absolute gain from a given increment to total income. Compensatory direct interventions can be important, provided they are integrated into a framework of fiscal and monetary discipline. The evidence does not suggest that growth is always distribution-neutral, and it would be wrong to conclude that changes in distribution are of little consequence. The point is not that distribution is irrelevant or that it never changes, but that its changes are roughly uncorrelated with economic growth. There is no intrinsic tradeoff between long-run aggregate efficiency and overall equity. Policies aimed at helping the poor accumulate productive assets--especially policies to improve schooling, health, and nutrition--when adopted in a relatively nondistorted framework, are important instruments for achieving higher growth.Services&Transfers to Poor,Environmental Economics&Policies,Economic Conditions and Volatility,Health Monitoring&Evaluation,Public Health Promotion,Achieving Shared Growth,Inequality,Governance Indicators,Safety Nets and Transfers,Rural Poverty Reduction
The impact of labor market regulations
Get PDFThe authors investigate the impact of labor market regulations in settings where compliance is incomplete. They review some stylized facts about labor market behavior, present an analytical model that may explain such behavior, and provide a checklist for assessing the distortionary impact of a regulation such as the minimum wage. They take as their starting point the limited evidence about the distortionary effects of such regulations and argue that there may be natural limits on the efficiency losses engendered by labor market regulations. First, the regulations may not be binding at market equilibrium. For example, minimum wages may be set so low that they are ineffective. Second, even if they are binding, the relevant elasticities of supply and demand may be so low that the regulations have little impact on efficiency. Third, even if the regulations are binding and elasticities are sizable, compliance may be low. The authors argue that the likelihood of compliance will be greatest when the regulations are binding and the relevant elasticities are sizable. That is, if the distortionary costs of regulations are not rendered insignificant by the first two reasons, then the returns to noncompliance will be high and, other things being equal, employers will evade or avoid the regulations, thereby minimizing the imact on efficiency. The argument rests on profit maximization subject to a hard budget constraint. Public enterprises, which are not concerned only with profit maximization and often have softer budget constraints than the private sector, may be more willing to conform to profit-reducing regulations, but in this case the authors argue that compliance may reduce already-existing efficiency losses.Environmental Economics&Policies,Health Monitoring&Evaluation,Labor Policies,Public Health Promotion,Banks&Banking Reform,Health Monitoring&Evaluation,Banks&Banking Reform,Municipal Financial Management,Poverty Assessment,Environmental Economics&Policies
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
