Fiscal space for investment in infrastructure in Colombia
Get PDFFor the evaluation of macroeconomic policies Colombian authorities rely heavily, if not exclusively, on the operational framework known as the Financial Programming Model developed by the International Monetary Fund in the 1950s. Based on this static framework, the formulation of fiscal policy in the country, just as in various Latin American countries, focuses primarily on fiscal deficit and gross debt targets. However, the type of fiscal policy advice derived from it is not useful for understanding the asset-creating nature and the inter-temporal tradeoffs involved in public investment decisions. The author develops a perfect foresight, dynamic small open economy model to provide an alternative framework for fiscal analysis and policy purposes. He shows that the two competing frameworks deliver differing paths for the expected behavior of the Colombian economy. He then uses the proposed framework to study the likely consequences of using public capital spending to achieve deficit targets since, in addition to an already high public debt, in the years ahead unfunded pension obligations will put enormous pressure on the Colombian government's solvency. The results indicate that public capital compression is costly in terms of foregone growth and very ineffective in achieving fiscal consolidation. The adoption of fiscal rules such as the golden rule or the permanent balance rule to shield public investment from undue budgetary pressures makes little sense in the presence of sustainability concerns. The author shows that a transitory capital spending increase is not self-amortizing in the long run; hence an extra peso of public capital spending deteriorates the inter-temporal fiscal position. A permanent increase largely pays for itself in terms of additional tax revenue but this effect is offset by a deterioration of infrastructure user charges, as long as public prices are determined competitively.Economic Theory&Research,Environmental Economics&Policies,Banks&Banking Reform,Public Sector Economics&Finance,Economic Stabilization
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
Raising revenue with transaction taxes in Latin america - or is it better to tax with the devil you know?
Get PDFIn recent years, various Latin American governments have resorted to taxes on bank debits and financial transactions as alternative ways of raising revenue. Considerable interest has developed in understanding the consequences of such reforms. The author constructs a dynamic general equilibrium model to assess the size of distortions and other quantitative implications associated with a transaction tax. The distinctive feature of the model is the non-neutrality property of the tax in the sense that it distorts the structure of relative prices of intermediate transactions, giving rise to tax"pyramidation."The effective tax rate ultimately borne by the economy is shown to depend on the complexity of the transaction structure. Calibrated for Latin America, the model finds that, contrary to existing evidence and conventional wisdom, a transaction tax is not a particularly burdensome levy in terms of economic growth and efficiency costs. The model also shows that if a government can credibly commit itself to an announced two-step reform in which it first uses a transaction tax temporarily and then replaces it with any other conventional tax, this policy will improve economic welfare relative to a tax reform where a consumption tax (or a labor income tax or a capital earnings tax) is exclusively used from the start to raise the required additional revenue.Public Sector Economics&Finance,Economic Theory&Research,Labor Policies,Environmental Economics&Policies,Banks&Banking Reform,Economic Theory&Research,Environmental Economics&Policies,Public Sector Economics&Finance,Banks&Banking Reform,Economic Growth
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
