Fundamentals, Contagion and Currency Crises: An Empirical Analysis

Mark Kruger, Patrick N. Osakwe, Jennifer Page
2000 Development Policy Review  
In cases where a significant relationship is found, the result is not robust in the sense that the relationship becomes insignificant when there is either a change in the sample size or the definition  ...  Our paper also provides empirical evidence in support of the idea that currency crises could be contagious.  ...  The difference between the two concepts is that currency crashes deal with successful speculative attacks alone while currency crises incorporate both successful and unsuccessful speculative attacks. on  ...

Empirics of currency crises: A duration analysis approach

Mohammad Karimi, Marcel-Cristian Voia
2019 Review of Financial Economics  
The main contributions are in three areas. First, it tests for contagious crises and attempts to recognize contagion channels by employing a duration analysis.  ...  This approach lets the researchers take into account both successful and unsuccessful attacks and, in a dynamic way, it distinguishes between before and after the attack periods.  ...  At the time of the attack the central bank should voluntarily devalue or float the exchange rate, otherwise intervention to support the fixed rate would not be successful and would only result in the instant  ...

Investigating the Comparability of Two Multi-Item-Scales for Cyber Bullying Measurement

Julia Fluck
2018 International Journal of Environmental Research and Public Health  
In the first study, the items cover victimization experiences while in the second study they cover estimation of severity.  ...  In current cyberbullying literature, researchers assess the phenomenon using a large variety of measurement approaches. This poses a problem in light of comparability of study results.  ...  A chi² difference test shows no significant difference in model fit.  ...

Defending against speculative attacks – It is risky, but it can pay off

Alexander Erler, Christian Bauer, Bernhard Herz
2014 Journal of Banking & Finance  
We find that a central bank has two options to mitigate the costs of speculative attacks, namely an immediate depreciation and a successful defense.  ...  defense or (iii) an unsuccessful defense in the case of an intervention.  ...  In particular, the very helpful comments by Brian Lucey, Mario Larch and Frank Westermann are gratefully acknowledged.  ...

Lei Jia, Yaxiong Sun, Alexandre G. de Brevern
2017 PLoS ONE  
In this work, we focus on prediction models for asparagine (Asn) deamidation.  ...  It still dominates deamidation evaluation process in most pharmaceutical setup due to its convenience.  ...  The side chain torsion chi2 is more important than chi1. Chi2 is closer to the nucleophilic attacked carbonyl than chi1. Backbone torsions are generally more important that the side chain torsions.  ...
