Sovereign risk in the Euro area: a multivariate stochastic process approach
In this paper we jointly model financial and real components of sovereign risk, by means of correlated stochastic processes, and apply the model to Euro Area countries.
For each country we consider, as a target measure, the Debt/GDP ratio. We model the time dynamics of both the Debt and the GDP by means of a linear combination of two stochastic equations: an Euro Area systematic process and a country specific idiosyncratic process.
Doing so, we provide an early warning predictive model of sovereign debt sustainability, considering both the financial and the real economy sides, and in terms of both common and country-specific factors.
We provide an estimation procedure for the parameters of the processes, which allows to calculate the implied probabilities of default for each country.
The empirical findings show a clear clustering effect between northern and southern countries, especially on the financial side. The inclusion of the GDP growth rate in the derivation of default probabilities partially changes the clustering structure, showing that the sovereign risk of some countries (especially that of France and Italy) is strongly affected not only by the debt evolution, but also by the growth of the GDP.1
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
The double materiality of climate physical and transition risks in the euro area
We analyse the double materiality of climate physical and transition risks in the euro area economy and banking sector. First, by tailoring the EIRIN Stock-Flow Consistent behavioural model, we provide a dynamic balance sheet assessment of the Network for Greening the Financial System (NGFS) scenarios. We find that an orderly transition achieves early co-benefits by reducing CO2 emissions (12% less in 2040 than in 2020) while supporting growth in economic output. In contrast, a disorderly transition worsens the economic performance and financial stability of the euro area. Further, in a disorderly transition with higher physical risks, real GDP decreases by 12.5% in 2050 relative to an orderly transition. Second, we analyse how firms’ expectations about climate policy credibility (climate sentiments) affect investment decisions in high or low-carbon goods. Firms that trust an orderly policy introduction do anticipate the carbon tax and switch earlier to low-carbon investments. This, in turn, accelerates economic decarbonization and decreases the risk of carbon-stranded assets for investors. Our results highlight the crucial role of early and credible climate policies to signal investment decisions in the low-carbon transition
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
Bail-In or Bail-Out? Correlation Networks to Measure the Systemic Implications of Bank Resolution
We propose a statistical measure, based on correlation networks, to evaluate the systemic risk that could arise from the resolution of a failing or likely-to-fail financial institution, under three alternative scenarios: liquidation, private recapitalization, or bail-in. The measure enhances the observed CDS spreads with a risk premium that derives from contagion effects across financial institutions. The empirical findings reveal that the recapitalization of a distressed bank performed by the other banks in the system and the bail-in resolution minimize the potential losses for the banking sector with respect to the liquidation scenario, thus posing limited systemic risks. A closer comparison between the private intervention recapitalization and the bail-in tool shows that the latter slightly reduces contagion effects with respect to the private intervention scenario
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
