Finansinis stabilumas ir koncentracija: besivystančios Europos tyrimas

2016

Šiame straipsnyje tiriamas bankų sektoriaus koncentracijos poveikis finansiniam stabilumui naudojant 134 komercinių bankų iš 17 Vidurio ir Rytų Europos šalių 2007-2012 m. laikotarpio duomenis. Empirinio tyrimo rezultatai pabrėžia vadinamąją „koncentracijos trapumo“ hipotezę, parodydami, kad aukštas koncentracijos lygis bankų sektoriuje yra siejamas su didesne bankų, ypač mažesniųjų, įsipareigojimų neįvykdymo tikimybe. Taip pat parodoma, kad neigiamas koncentracijos poveikis gali būti sumažintas taikant griežtą priežiūros sistemą. Pirmiausia - griežtas oficialus bankų sektoriaus priežiūros įgaliojimas. Antra - skirtingi priimančiosios šalies ir buveinės šalies priežiūros įgaliojimai gali žym…

Financial Sector Reform After the Crisis: Has Anything Happened?

2013

We analyze the reactions of stock returns and CDS spreads of banks from Europe and the United States to four major regulatory reforms in the aftermath of the subprime crisis, employing an event study analysis. In contrast to the public perception that nothing has happened, we find that financial markets indeed reacted to the structural reforms enacted at the national level. All reforms succeeded in reducing bail-out expectations, especially for systemic banks. However, banks' profitability was also affected, showing up in lower equity returns. The strongest effects were found for the Dodd-Frank Act (especially the Volcker rule), whereas market reactions to the German restructuring law were …

German Bank Lending During Emerging Market Crises: A Bank Level Analysis

2007

This paper studies German bank lending during the Asian and Russian crises, using a bank level data set, which has been compiled from credit data at the Deutsche Bundesbank. Our aim is to gain more insight into the pattern of German bank lending during financial crises in emerging markets. We find that German banks reacted to the Asian crisis mainly by reallocating their portfolios among emerging markets. This behaviour is consistent with active portfolio management and does not necessarily indicate a spontaneous reaction to the Asian crisis. By contrast, the banks' behaviour during the Russian crisis is characterised by a general withdrawal from emerging markets. The use of micro data allo…

Does the EMU Need a Fiscal Transfer Mechanism?

2004

Summary: The aim of this paper is to investigate how the birth of a central fiscal authority or the creation of a fiscal transfer mechanism could improve the action of fiscal policy in terms of stabilization in the EMU. In particular, the paper examines the theoretical reasons to support this conclusion and provides empirical evidence that shows how the EMU is not able to face asymmetric and symmetric idiosyncratic shocks. Zusammenfassung: Die zentrale Frage des Aufsatzes lautet: Ob und wie kann eine zentrale Fiskalbehorde oder ein fiskalischer Transfermechanismus die fiskalpolitische Stabilisierung in der EWU verbessern? Dazu werden theoretische Argumente und empirische Evidenz prasentiert…

Modeling the electromechanical impedance technique for the assessment of dental implant stability

2015

We simulated the electromechanical impedance (EMI) technique to assess the stability of dental implants. The technique consists of bonding a piezoelectric transducer to the element to be monitored. When subjected to an electric field, the transducer induces structural excitations which, in turn, affect the transducer's electrical admittance. As the structural vibrations depend on the mechanical impedance of the element, the measurement of the transducer's admittance can be exploited to assess the element's health. In the study presented in this paper, we created a 3D finite element model to mimic a transducer bonded to the abutment of a dental implant placed in a host bone site. We simulate…

Fiscal Rules and Macroeconomic Stability

2005

In this paper we analyze the impact of fiscal rules on the effectiveness of fiscal policy as a macroeconomic stabilizing instrument. First, we review the available evidence on the effects of fiscal policy to affect output in the short run and real interest rates and investment and growth in the long run, and we show how the use of fiscal rules has proved useful in restraining debt and deficits. Secondly, we discuss if debt consolidation rules trade off higher output instability in exchange for lower deficits, using three alternative representations of the intertemporal substitution mechanism in a SDGE framework. Our main conclusion is that both the impact of discretionary fiscal policy and …

Stability and synthesis of superheavy elements: Fighting the battle against fission – example of $^{254}$No

2016

International audience; Superheavy nuclei exist solely due to quantum shell effects,which create a pocket in the potential-energy surface of the nucleus, thusproviding a barrier against spontaneous fission. Determining the height ofthe fission barrier and its angular-momentum dependence is important toquantify the role that microscopic shell corrections play in enhancing andextending the limits of nuclear stability. In this talk, the first measurement ofa fission barrier in the very heavy nucleus 254No will be presented.

Network Physiology of Cortico–Muscular Interactions

2020

Skeletal muscle activity is continuously modulated across physiologic states to provide coordination, flexibility and responsiveness to body tasks and external inputs. Despite the central role the muscular system plays in facilitating vital body functions, the network of brain-muscle interactions required to control hundreds of muscles and synchronize their activation in relation to distinct physiologic states has not been investigated. Recent approaches have focused on general associations between individual brain rhythms and muscle activation during movement tasks. However, the specific forms of coupling, the functional network of cortico-muscular coordination, and how network structure a…

Behavior adaptation and selection.

2010

6 pages; The evolutionary approach to behavior is concerned with the evolutionary origin and adaptive function of behavioral traits. Like any other part of the phenotype, behavior can be shaped by natural selection to produce adaptations. However, behavior often shows large phenotypic variation and flexibility, and can be both – subject to selection and a major agent of selection. Therefore, the study of adaptation and evolution of behavior is a particularly complex one, involving a wide range of methodologies and techniques, including mathematical modeling, comparative methods, phenotypic engineering, quantitative genetics, genetic dissection, and artificial selection.
