Three Essays in International Economics
This dissertation consists of three essays on the impact that import competition and importing opportunities can have on households. Specifically, I aim to quantify the effects that reductions in trade costs and access to new inputs have on income and on the menu of options available to consumers. I achieve these goals by focusing on the differential impact of import competition on workers with different occupations and different skill levels, and by examining the extent to which import opportunities change firms' output decisions.
Chapter 1 examines the role of occupations in understanding who gains and who loses from changes in import costs. From estimating a structural model of the Danish labor market, I find that a substantial portion of the variation in income changes induced by the decline in import costs from 1996 to 2005 is accounted for by one's occupation at the time that costs decrease. Moreover, I find that when workers must engage in costly occupational reallocation, the short run variation in changes to workers' incomes can be substantially larger than in the long run.
While chapter 1 explores how workers' incomes respond to changes in import costs, chapter 2 focuses on how firms respond to new importing opportunities. This chapter, co-authored with Valerie Smeets and Frederic Warzynski, uses data on Danish apparel firms to estimate how firms change the quality of their goods when trade costs decrease. We find that access to imports from poorer countries tends to lead firms that produce lower quality goods to upgrade their products, and firms that produce higher quality goods to downgrade theirs. Thus, import competition tends to reduce the dispersion in quality of domestically produced goods.
Finally, in the third chapter, I return my focus to workers to explore how the elasticity of substitution between imported intermediates and workers of different skill levels varies across industries. I find significant heterogeneity in this parameter across industries and build a model to demonstrate how this elasticity of substitution can affect how wages between skilled and unskilled workers responds to changes in import costs
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
Foxes and Hedgehogs: The Role of Personality in Labor Market Adjustment
We study the role of personality and non-cognitive skills in labor market adjustment in response to trade shocks. Specifically, we focus on how these traits mediate the adverse consequences for U.S. workers of rising Chinese imports. We identify plausibly exogenous variation in Chinese import competition across industries in the U.S. using the instrument of Pierce and Schott (2016) and find that personality characteristics (as identified by the Big Five personality test and measures of locus of control) are correlated with an individual’s propensity to switch industry, occupation, and transition out of employment in response to a trade shock. These results are important for understanding labor market adjustment costs, which are a key determinant of the welfare and distributional impacts of trade. For example, these traits can help explain the concurrent increase in mortality of workers dislocated by import competition. The efficacy of job retraining and trade-related retraining also hinge on understanding dislocated workers’ non-cognitive as well as cognitive traits
Appropriate Similarity Measures for Author Cocitation Analysis
We 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
We 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
We 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
