Conflict, climate, and cells: a disaggregated analysis
No full textWe conduct a disaggregated empirical analysis of civil conflict at the subnational level in Africa over 1997 to 2011 using a new gridded data set. We construct an original measure of agriculture-relevant weather shocks exploiting within-year variation in weather and in crop growing season and spatial variation in crop cover. Temporal and spatial spillovers in conflict are addressed through spatial econometric techniques. Negative shocks occurring during the growing season of local crops affect conflict incidence persistently, and local conflict spills over to neighboring cells. We use our estimates to trace the dynamic response to shocks and predict how future warming may affect violence
Essays in development economics
No full textThesis: Ph. D., Massachusetts Institute of Technology, Department of Economics, 2016.Cataloged from PDF version of thesis.Includes bibliographical references (pages 149-159).This thesis consists of three essays in development economics. The first chapter investigates urban form in India. I focus on one of the determining factors of urban commuting efficiency, highlighted by urban planners but overlooked by economists: city shape. I retrieve the geometric properties of urban footprints in India over time, using satellite data on nighttime lights and historic maps. I propose an instrument for urban shape based on the interaction between topographic obstacles arid mechanically predicted city growth. I then investigate how city shape affects the location choices of consumers and firms, in a spatial equilibrium framework. More compact cities are characterized by larger population, lower wages, and higher rents, consistent with compact shape being a consumption amenity. The welfare cost of deteriorating city shape is estimated to be sizeable. The effects of unfavorable topography appear to be exacerbated by building height restrictions, and mitigated by infrastructure. The second chapter examines the human capital effects of inheritance law in Kenya. I study a 1981 statutory law reform granting Kenyan women equal inheritance rights. I employ a difference-in-differences strategy, exploiting variation in pre-reform inheritance rules across religious groups. Women exposed to the reform are more educated, less likely to undergo genital mutilation and more likely to be medically assisted during childbirth; they also tend to delay childbearing and to have better marriage market outcomes. These effects are more pronounced for women with fewer siblings, for whom the absolute inheritance share is potentially larger. In the third chapter, my coauthor Eliana La Ferrara and I conduct a disaggregated empirical analysis of civil conflict at the sub-national level in Africa over 1997-2011, using new gridded data. We construct an original measure of agriculture-relevant shocks exploiting within-year variation in weather and in crop growing season, and spatial variation in crop cover. Temporal and spatial spillovers in conflict are addressed through spatial econometric techniques. Negative shocks during the growing season of local crops affect conflict incidence persistently, and local conflict then spills over in space. We use our estimates to trace the dynamic response to shocks and predict how future warming may affect violence.by Mariaflavia Harari.Cities in Bad Shape: Urban Geometry in India -- Women's Inheritance Rights and Bargaining Power: Evidence from Kenya -- Conflict, Climate and Cells: a Disaggregated Analysis.Ph.

The Effect of Culture on the Functioning of Institutions: Evidence from European Regions
No full textColonial Legacy and Land Market Formality
Full text linkWe study the role of Dutch colonial institutions on urban development for the megacity of Jakarta, Indonesia. Using historical maps of Dutch settlements and a rich granular database, we implement a boundary discontinuity design comparing locations within 200 meters of Dutch boundaries. We find that historical Dutch areas today have significantly lower parcel density, are more likely to have formally registered parcels, and have more regular parcel layout, pointing to the importance of planning and mapping. Dutch settlements are also more likely to appear formal, as per a photographic index that ranks the appearance of neighborhoods. More broadly, Dutch areas are 11 percentage points more likely to have tall buildings (with more than 3 floors) and have 17 log points higher assessed land values. We consider channels such as natural advantage, direct Dutch investments, and land market institutions
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
