Finance and Market Concentration Using Agent-Based Modeling: Evidence from South Korea
No full textThis study investigates the role of finance in shaping the global trend of increasing market concentration. Using agent-based modeling (ABM), we conduct qualitative and quantitative analyses to examine the impact of financial policies on market concentration. Additionally, we analyze their simultaneous effects on economic growth and labor income share as key macroeconomic indicators. Building upon the Keynes meets Schumpeter (K+S) model, we conduct policy experiments using a model validated against the historical trends in South Korea. For the policy variables, we apply the debt-to-sales ratio (DSR) limit and interest rate as levers to regulate the quantity and cost of finance, respectively. The simulation results show that lowering interest rates alleviates market concentration while DSR regulation exhibits nonlinear effects on it.As the DSR limit increases, market concentration initially decreases but rises again beyond a certain threshold. To investgiate the rationale behind this phenomenon, we examine how finance affects individual firms at a micro level through firm-level analysis. Our findings underscore the value of ABM in addressing this complex issue from both the micro and macro perspectives. Moreover, they highlight that the impact on market concentration varies based on the nature of financial policies, and suggest that coordinating DSR regulatory policies with monetary policies such as interest rates can help policymakers manage market concentration.
Jurassic-Lower Cretaceous stratigraphy and palaeogeographic evolution of the Southern part of Northwestern Anatolia (Turkey)
No full textExtinction, survival, and recovery of lagenide foraminifers in the permian-triassic boundary interval, central Taurides, Turkey
No full textThe assemblage of lagenide foraminifers in uppermost Permian rocks of the central Taurides consists of 22 species ill 16 genera. including the new species Rectostipulina pentamerata, plus additional unidentified elements. Of these, only two identifiable species in "Nodosaria" and indeterminate syzraniids survived the end-Permian mass extinction. The last occurrences of most taxa fall within the upper half-meter of the Permian System, a pattern consistent with abrupt extinction when tested for the Signor-Lipps effect. Permian survivors are joined locally in the Lower Triassic and lower Middle Triassic by three additional species. Globally, lagenide species diversity remained low until latest Anisian time, and probably did not reach pre-extinction levels until Late Triassic or Early Jurassic time. The survival of the lagenide clade, in contrast to the complete elimination of fusulinoidean fusulinides, may be linked to the lagenides' comparatively greater paleoenvironmental tolerances and wider paleogeographic distribution. Evaluation of lagenide extinction and survival across the Permian-Triassic boundary in the central Taurides is complicated by a facies change from bioclastic wackestones and pack-stones to oolitic grainstones near the top of the Permian, and by the development of variably dolomitized and pyritic stromatolites and overlying oolites in the lowest Triassic. The stromatolitic and oolitic Lower Triassic lithologies represent a sedimentologic response to the end-Permian mass extinction and unusual Early Triassic marine environments. Stromatolites likely became established as disaster forms in all ecologically permissive period that lacked normal marine grazing and bioturbating benthos. Their calcification and preservation may have been promoted by high carbonate saturation levels. Oolites, which are found in recurring facies associations with stromatolites and other anachronistic carbonates in Lower Triassic rocks throughout the Tethyan embayment. probably also formed in response to elevated saturation levels and the absence of a skeletal sink for carbonate
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
Decapoalina n. gen. (Miliolata, Milioliporidae; Late Triassic), a new foraminiferal genus for “Sigmoilina” schaeferae Zaninetti, Altiner, Dager & Ducret, 1982
No full textThe wall of the type specimens of “Sigmoilina” schaeferae Zaninetti, Altiner, Dager & Ducret, 1982, described from thin sections of the Norian-Rhaetian reef limestone of the Taurus Mountains (Turkey), originally interpreted to be porcelaneous imperforate, is micritized. In this study, the presence of coarse pseudopores is demonstrated in the specimens collected from the Rhaetian Dachstein-type reef limestone of Mt. Begunjščica (southern Karavanke Mts, northern Slovenia) and the new genus Decapoalina Gale, Rettori & Martini, is established to comprise this particular species
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
