Trade, Growth, and the International Transmission of Financial Shocks
Get PDFThis study develops a two-country model to explore how financial shocks in one country affect its partner country's business cycles through international trade. Unlike existing studies, I introduce the mechanism of endogenous trade patterns, by which a shock can affect both the intensive and extensive margins of trade. I also embed the mechanism of endogenous growth into the model to indicate the potential for prolonged recessions, even for a transitory shock. I obtain the following four main findings. First, an adverse financial shock in one country induces a global recession, even in the absence of international financial transactions. Second, although the downward shift of real GDP in the partner country is not so large, it can be very prolonged. Third, the real value of exports in the partner drops more seriously than its real GDP. Finally, this drop is caused mainly by a change at the intensive margin rather than the extensive margin
Financial Shocks to Banks, R&D Investment, and Recessions
Get PDFIn some classes of macroeconomic models with financial frictions, an adverse financial shock successfully explains a drop in GDP, but simultaneously induces a stock price boom. The latter theoretical result is not consistent with data from actual financial crises. This study develops a simple macroeconomic model featuring a banking sector, financial frictions, and R&D-led endogenous growth to examine the impacts of an adverse financial shock to banks on firms' R&D investments and equity prices. Both the analytical and numerical investigations show that a shock that hinders the banks' financial intermediary function can be a key to generating both a prolonged recession and a drop in the firms' equity prices
International Transmission of Financial Shocks without Financial Integration
Get PDFThis study analyzes how financial shocks in one country transmit to another country through international trade. To this end, it develops a dynamic general equilibrium model of two-country Ricardian trade with a continuum of goods. Financial frictions exist in each country and the two countries can be asymmetric in terms of the degree of frictions, which can be a novel source of comparative advantage. In the case of a permanent credit crunch, we can analytically show that such a shock reduces the long-run investment, GDP, wage income, and aggregate income of heterogeneous entrepreneurs in both countries. We also numerically investigate the transitory responses to a temporal credit shock and show that such an internationally synchronized economic downturn is also observed during transition periods
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
Welfare Implications of Non-unitary Time Discounting
Get PDFThis study proposes a model of non-unitary time discounting and examines its welfare implications. A key feature of our model lies in the disparity of time discounting between multiple distinct goods, which induces an individual's preference reversals even though she normally discounts her future utilities for each good. After characterizing the time-consistent decision-making by such an individual in a general setting, we compare welfare achieved in the market economy and welfare in the planner's allocation from the perspective of all selves across time. Under certain situations, the selves in early periods strictly prefer the social planner's allocation, whereas the selves in future periods strictly prefer the market equilibrium. Therefore, the welfare implications of our model are quite different from those in the canonical discounting model and in models of other time-inconsistent preferences
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
