Business Failures, Macroeconomic Risk and the Effect of Recessions on Long-Run Growth: a Panel Cointegration Approach
No full textUdgivelsesdato: Nov.-Dec.This paper uses panel data on Italian regions to test two competing theories of long-run productivity dynamics: the opportunity-cost model, according to which productivity-enhancing activities have a comparative advantage during recessions; and the risk-aversion model, which predicts a negative relationship between transitory disturbances and productivity growth. Panel ECM estimates suggest that macroeconomic risk factors impinge on business failures on the same direction both in the short and in the long-run, and that the adjustment to the steady-state relationship is quite slow. Thus, our findings lend support to the risk-aversion theory of productivity growth and indicate that bankruptcy risks play a significant role in the propagation of macroeconomic shocks
Financial Markets imperfections, heterogeneity and growth
Full text linkThis paper offers a model of growth with heterogeneous agents in which, due to asymmetric information, financial markets do not work properly. In such a world, the Modigliani-Miller theorem fails to hold, a financial hierarchy emerges and ‘how to finance’ the engine of growth – in our case represented by uncertain endeavours in R&D - matters. In turn, heterogeneity means that agents lack sufficient information on the behaviour adopted by the others, forcing them to make use of naive rules in forming expectations and in calculating their probability of bankruptcy. The basic properties of the model are explored via simulations. In particular, it is possible to appreciate how a worsening of financial conditions (e.g. an increase of the contractual interest rate on loans or of the probability of bankruptcy) affects negatively the long-run average rate of growth
Clearing mechanism in real and financial markets
Full text linkThe present thesis is a collection of contributions concerning the application of the clearing principle in real and financial markets. In particular, two issues are deepened. The first concerns the effect of bilateral clearing of interbank deposits in the reduction of systemic risk. The second focuses on the endogenous formation process of clearing houses that manage payments. The methodology applied in the three contributions is the network analysis combined with agent-based models and computer simulations. The work is structured in four sections. The first defines and describes the more popular clearing agreements from a legal and economic point of view and provides a presentation of the three collected papers. The second section investigates the effect of bilateral netting on financial stability during a liquidity crisis. The third section analyzes how bilateral netting affects the resilience of an interbank credit network in the event of a shock affecting the assets of an intermediary. The fourth section analyzes the endogenous formation of clearing houses in both corporate barter circuits and interbank payment networks
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
