Credit Rating Agency Announcements and the Eurozone Sovereign Debt Crisis
This paper studies the impact of credit rating agency (CRA) announcements on the value of the Euro and the yields of French, Italian, German and Spanish long-term sovereign bonds during the culmination of the Eurozone debt crisis in 2011-2012. The employed GARCH models show that CRA downgrade announcements negatively affected the value of the Euro currency and also increased its volatility. Downgrading increased the yields of French, Italian and Spanish bonds but lowered the German bond's yields, although Germany's rating status was never touched by CRA. There is no evidence for Granger causality from bond yields to rating announcements. We infer from these findings that CRA announcements significantly influenced crisis-time capital allocation in the Eurozone. Their downgradings caused investors to rebalance their portfolios across member countries, out of ailing states' debt into more stable borrowers' securities
The Power of Opinion: More Evidence of a GIPS-Markup in Sovereign Ratings During the Euro Crisis
This paper examines whether the Big Three credit rating agencies actually played as active a role in the Euro Crisis as previously asserted. On the basis of panel data methods for a set of 11 EMU countries, the analysis reveals significant evidence for an arbitrary markup on the GIPS group of countries across agencies. This markup, which ranges from 1.5 notches for Moody's to 2.2 notches for S&P, suggests that GIPS countries were treated worse than other EMU members since the start of the Eurozone crisis in 2009, irrespective of economic and institutional fundamentals. A subsequent analysis of the markup's effect on yield spreads shows that this markup had significant effects on financial markets, leading to risk premiums for these countries of up to 1.6 points
Adverse events in faecal microbiota transplant: a review of the literature.
Faecal microbiota transplant (FMT) is the infusion of donor faeces into the gut with the aim of improving microbial diversity. The procedure has gained significant interest recently in the treatment of recurrent Clostridium difficile infection (CDI). The literature is currently dominated by small case series and isolated case reports. There is no standardization of methods and recording of outcomes.Submitted (immediately with CC-BY-NC-ND), or accepted after 12 month embargo (CC-BY-NC-ND
Our Experience with Vaginal Prostaglandin-E2 for Induction of Labor in Qatar: Six Months Review
In order to review our experience with prostaglandin-E2 for the induction of labour and to evaluate its safety and outcomesa retrospective study was carried out at the Women's Hospital, Hamad Medical Corporation, over a six-month period. Three hundred and thirty four patients (7% of total deliveries) were induced by PGE2 (Dinoprostone), including 105 (30%) nulliparae and 229 (70%) multiparae. Patients with a history of one previous lower segment caesarean section were also included. Post date pregnancy and diabetes were the most common indications for induction.
There were significant differences in the two groups regarding the number of doses and the mean total dose of PGE2 used. The need for syntocinon augmentation was more in the nulliparae (41% vs 22%). Failed induction occurred only in nulliparae. The rate of caesarean section in induced labour remained significantly low compared with a spontaneous labour (11.6% vs 10.7%). The caesarean section rate was higher in the nulliparae (16.0% vs 9.6%) but this was not statistically significant. The caesarean section rate was higher when Bishop score 0-4 (76% vs 24%). Only two of the babies in the study group had an Apgar score less than 7 at 5 minutes. There was one caesarean hysterectomy because of postpartum hemorrhage associated with the PGE2 induction.
Conclusion: The calculated induction rate with PGE2 was 7% of total deliveries. Induction of labour with PGE2
in a grandmultiparae and previous caesarean section is relatively safe but further multicentre studies are needed to confirm our findings.</jats:p
Sovereign rating changes and realized volatility in Asian foreign exchange markets during the Asian crisis
This article explores the impacts of sovereign rating changes by multiple rating agencies on foreign exchange rate volatility during the Asian crisis. We extend the existing literature to explore the impacts of multiple agency sovereign rating changes on the realized volatility of foreign exchange markets. Our findings show that the rating downgrades are associated with increases in foreign exchange volatility, and that multiple downgrades lead to a much higher increase in volatility as compared to single downgrades. Our results demonstrate that rating downgrades are part of the important news for the national markets consistent with the analysis of contagion analysis in Baur and Fry (2006, 2009).realized volatility, sovereign rating changes, foreign exchange market,
Reforming Rating Agencies
Rating agencies have been under the spotlight since the beginning of the century. Financial disasters and the subprime crisis of 2008 brought about the birth of such preoccupations as many investors and regulators became sceptical about their activities. In this chapter, the authors highlight the main characteristics of this activity, sum up the criticisms they had to face, analyse the usefulness of the agencies for investors and the financial market as a whole, and present some possible paths for reforming rating agencies
