Temas tradicionales sobre ciclos Stop-Go y devaluaciones contractivas
Get PDFEl interés por estudiar con una perspectiva analítica rasgos particulares del desempeño macroeconómico del país tiene larga historia en la Argentina. En los 1960s y 1970s, un rico conjunto de trabajos investigó patrones de comportamiento salientes, como las intensas fluctuaciones de actividad y precios asociadas con la variable disponibilidad de divisas (stop go). En este artículo se vuelve sobre estos temas, en un marco analítico similar al empleado en la literatura tradicional, y poniendo énfasis en las implicancias de las restricciones macroeconómicas de presupuesto. Los resultados permiten precisar condiciones para la validez de efectos como las devaluaciones contractivas.Fil: Heymann, Daniel. Universidad de Buenos Aires. Facultad de Ciencias Económicas.

Ciclos en la distribución del presupuesto nacional entre provincias en contextos de asimetría de información entre votantes : teoría y evidencia para Argentina
Get PDFFil: Nakab, Alejandro. Universidad de San Andrés. Departamento de Economía; Argentina.En este estudio se analiza cómo son los ciclos en la distribución del presupuesto nacional entre
provincias en contextos donde el gobernante quiere permanecer en el poder y donde existe asimetría
de información entre votantes. Se plantea un modelo teórico en el cual el gobernante maximiza la
probabilidad de ser reelecto (eligiendo el nivel de transferencias óptimas), explotando la asimetría de
información entre votantes. Asimismo, los votantes presentarán una estrategia de votación
retrospectiva en donde premiarán o castigarán al incumbente votando o no por su reelección según
el bienestar directo que hayan recibido de dichas transferencias y según un juicio de valor sobre el
candidato basada en la distribución relativa de las transferencias entre regiones. Es así, que el voto
dependerá del bienestar directo de las transferencias y de la percepción que tengan del incumbente.
Particularmente, controlando por variables sociodemográficas y políticas, se encuentra que los
gobernantes benefician con mayores transferencias a las regiones más informadas por sobre las
menos informadas y que dicha diferencia se acrecienta en los años electorales, generando un ciclo
en la distribución del presupuesto. Además, se testea el modelo empíricamente para el caso de
Argentina, utilizando la inversión en servicios sociales y de salud del gobierno central en las
provincias y la circulación de diarios en dichas provincias como proxy de la variable de información.
Se halla evidencia congruente con las conclusiones teóricas presentadas
Public versus private pricing of real estate and fundamental value discovery
Get PDFFil: Nakab, Sebastián. Universidad de San Andrés. Departamento de Economía; Argentina.This paper examines the relationship between Real Estate Investment Trust ("REIT") stock prices and the value of direct real estate owned by REITs for the past 8 years. Using panel VAR models, we argue and find evidence that REIT prices explain private market valuations and can be used as a leading indicator of nominal cap rate movements and, effectively, net asset values. In fact, we show that no new information on values that affects REITs trading performance is baked into research estimates of private market valuations. We are able to get to these conclusions based on weekly data from Green Street Advisors (Wall Street's most respected real estate research firm) on nominal and implied capitalization rates as well as net asset values from November, 2011 through August, 2019
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

Essays on Workers' Human Capital Accumulation and Wage Experience Profiles
Get PDFThis dissertation consists of three chapters. Chapter 1 and Chapter 2 jointly offer an explanation for why workers in richer countries have faster rates of wage growth over their lifetimes than workers in poorer countries. We propose that workers in richer economies receive more firm-provided training. In Chapter 1, we document two main facts: the share of workers who receive firm-provided training increases with development, and that this is a key determinant of worker human capital investments. In Chapter 2 we build a general equilibrium search model with firm-training investments and frictional labor markets. Our model suggests firm-training accounts for a large share of the cross-country wage growth differences. We find that self-employment is a key factor explaining the lack of training in the poorest economies, whereas labor market frictions are key to explaining training differences within firms as countries develop. Finally, our model predicts considerable inefficiencies in human capital investments and sizeable aggregate gains from training subsidies to firms, which may be particularly desirable in poor countries where economic environments disincentivize training. Chapter 3 studies how exporting shapes experience-wage profiles. Using detailed Brazilian employer-employee and customs data, we document that workers' experience-wage profiles are steeper in exporters than in non-exporters. Aside from self-selection of firms with higher returns to experience into exporting, we show that workers' experience-wage profiles are steeper when firms export to industrialized destinations. We propose that this result is likely driven by faster human capital accumulation of workers in firms that export to advanced economies. To support our preferred hypothesis, we use the World Bank Enterprise Surveys and document that exporters are more likely to train workers than non-exporters, especially when they adopt foreign technology
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
