A Simple Early Warning System for Evaluating the Credit Portfolio's Quality
Nicolae Dardac,Iustina Alina Boitan
Theoretical and Applied Economics , 2009,
Abstract: The last decade has witnessed the development of a vast literature devoted to the study of several phenomena like banking crises or episodes of vulnerability and distress, characterized by inadequate capitalization, impairment of the asset quality and of the credit institutions' rating. The purpose of this study is to design an early warning system in order to highlight at an earlier stage the likelihood of deterioration of the Romanian banking system credit portfolio's quality. We have applied an econometric model which constitutes a reference for this type of analysis, having as purpose the identification of a significant correlation between increasing weight of bad loans in total assets, on the one hand, and a number of macroeconomic variables and indicators of the banking system, on the other hand.
Malmquist Index, an Alternative Technique for Measuring Credit Institutions Productivity
Nicolae Dardac,Iustina Alina Boitan
Theoretical and Applied Economics , 2008,
Abstract: The present study tackles the banking system’s productivity in a more complex manner, that integrates multiple input, multiple output variables, abdicating from the reductionist perspective of clasical methods, which imposed limits in the number of variables, in the process of productivity measurement and interpretation. The advantage of Malmquist productivity indexes consists both in a quantitative evaluation of the global productivity of a credit institution over a specified period of time, and in the decomposition of productivity, in order to underline how much of its change is due to the catch-up effect, and, respectively, to the implementation of new technologies. The results obtained revealed that credit institutions placed on the first three places in the banking system, according to assets value, maintained constant their productivity level during the analysed period, meanwhile the other institutions in our sample registered a slowly improvement in productivity, determined, mainly, by technological changes.
Evaluation of Individual and Aggregate Credit Institutions Management’s Performance
Nicolae Dardac,Iustina Alina Boitan
Theoretical and Applied Economics , 2008,
Abstract: Data Envelopment Analysis method allows both the measurement of the relative efficiency of an homogenous group of credit institutions, and the identification of those banking activity’s components generating a state of inefficiency. The present study focuses on this last issue, by proposing an interpretation of inefficiency signals and by strengthening the major role played by the credit institution’s executive board in designing a viable, coherent business strategy and in defining its risk profile.DEA method places all the efficient credit institutions on the efficiency frontier, without allowing their differentiation. In order to exceed this limit, we have analysed and compared two ranking techniques. The results obtained suggest that the hierarchy generated by the two techniques hasn’t changed significantly for almost 60% of our sample of credit institutions.
Implications of the single supervisory mechanism on ECB's functions and on credit institutions' activity
Teodora Cristina BARBU,Iustina Alina BOITAN
Theoretical and Applied Economics , 2013,
Abstract: The European Commission's proposal launched on September 12, 2012 for conferring the European Central Bank extended powers in the field of Euro zone banking supervision has become a hotly debated topic across EU member states. Until now, there is still strong resilience of the EU countries outside the single currency area.The prospects for its practical implementation raised, however, a series of questions related to its technical feasibility. Our paper intends to shed light on some issues concerning the implications of the single monitoring mechanism on the traditional functions of the ECB, on the coexistence between supranational supervision and the national one, and on various facets of the impact that the new architecture of European banking supervision will have on the business of credit institutions, in terms of performance indicators, efficiency, risk and competition.

Abstract: Bank performance measurement, as an expression of banks’ ability to generate sustainable profits, is a topic of major interest, located in the core of all categories of participants involved in the banking business: banking supervisory authorities, rating agencies, shareholders, investors and analysts of banking activity. Recent developments in bank profitability during the global financial crisis have highlighted a number of limitations of traditional banking performance measurement indicators, in respect of their capacity to provide relevant, credible and genuine information related to credit institutions’ activity. In this article we intend to argue, by investigations at conceptual and quantitative level, the extent to which traditional indicators of bank profitability provide a comprehensive and real insight into the credit institutions’ financial performance. The empirical study applies the stress test methodology, through which is assessed the extent to which Romanian banking system‘s performance, represented by ROE, changes in the context of defining adverse, but plausible scenarios. Hence, it had been simulated ROE’s degree of response for three types of scenarios. We have applied both univariate stress tests (sensitivity analysis) in order to isolate the potential impact of each risk factor on bank profitability, and multivariate stress tests, which allow the simultaneous application of multiple shocks on risk factors. The results show the most important risk factors that adversely affect banking system’s profitability and the concrete value by which profitability is expected to decrease for each scenario analyzed.
Impact of Credit Restructuring on the Quality of Bank Asset Portfolio. A Cluster Analysis Approach
Nicolae Dardac,Teodora Cristina Barbu,Iustina Alina Boitan
Acta Universitatis Danubius : Oeconomica , 2011,
Abstract: In this paper we proposed an analysis of the financial crisis impact on the procedures formanagement of loan portfolios in several banking systems. Despite ample liquidity injectionprograms implemented by major central banks and government actions, credit risk remains a keychallenge of the current banking systems. On a medium term, the high percentage of bad loans hasbecome a structural vulnerability. To maintain an acceptable quality of loan portfolios and not todamage the prudential and profitability indicators, credit institutions in EU member states haveproceeded to apply various techniques for credit restructuring. The quantitative analysis carried out inthe last part of the paper revealed a relatively moderate granularity of banking systems considered, interms of capitalization, volume of bank reserves and net provisions, in response to the persistent trendof loan portfolio deterioration.

Abstract: The purpose of this study is to assess to what extent the business model practiced by investment banks, before the beginning of the financial crisis, has influenced their performance indicators, and especially those who express shareholders' satisfaction. To this end, we have applied a nonparametric method, called Data Envelopment Analysis, which allows obtaining the efficiency scores for each financial institution considered. The sample included two pure investment banks, Lehman Brothers and Goldman Sachs, and seven international financial groups carrying out investment banking activities. The model tested assumed the maximization of selected output variables (ROE and the dividend distributed), by considering several input variables, meant to summarize the risk profile and costs arising from implementing a particular business model. The results obtained, in the form of high inefficiency scores, indicate that the business model of investment banks was not better performing than that applied by financial groups, because it failed to ensure a balance between ownership compensation and sustainable expansion of financial activity.
Central Banks’ Response to the Current Financial Crisis – Between Costs and Benefits
Teodora Cristina Barbu,Iustina Boitan
International Journal of Economics and Financial Issues , 2012,
Abstract: Our study is inserted in the thematic area dedicated, during recent years, to the research on central banks’ response to financial crisis. The global financial crisis has outlined a series of weaknesses located at regulatory and supervisory activities’ level, causing major central banks to face a new operating environment, in which traditional monetary policy tools are ineffective (key interest rate close to zero) in restoring the financial markets’ proper functioning. The unconventional monetary policy measures, the dramatic fall of the key interest rate, the balance sheet structure modification and extension of collateral accepted by central banks are the main issues on which we focused our attention, to highlight the costs and benefits recorded by these institutions. All major central banks have implemented highly innovative, flexible facilities and the main beneficiaries have been the banking systems in their entirety.
Northern Labyrinth—A Key to Time, Space, Information  [PDF]

Natural Resources (NR) , 2013, DOI: 10.4236/nr.2013.44042

Northern labyrinths are stone constructions of different shapes, dating back to III-I century BC. They mainly appear on capes on peninsulas and islands up to 13-25 metresabove the sea level. Their area begins from Scilly Isles (England) and in the White Sea (Russia). Opinions of scientists concerning their designation are controversial. Assumptions about their practical meaning haven’t been proved: no burials have been found underneath; fishing equipment cannot be located so far from the area of tides. Most of the scientists link labyrinths with the sphere of spiritual culture: sanctuaries, altars, sacred places, schemes of rituals and magical centers. Assumptions about calendar designation link the picture of labyrinth with schemes of orbits of the Sun, the Moon, planets and stars. However they do not explain the application of this technology. The author’s concept is based on the opposite astronomical alignment by the shade of gnomon and considers peculiarities of the geographical space of Northern regions (polar days and white nights). The aim of the research is to prove that the key to decoding the picture of a classic Northern labyrinth is a gnomon located in the centre of the construction. Field research has been conducted on Zayztskiy Island in Solovetskiy Archipelago. Experiments of imitation modeling have been done, analysis of linguistic and toponymic materials, archeological, astronomical, ethnographical and mythological and other sources has been implemented. The research has proved that observations of the shade can help to create a calendar in a shape of a bispiral labyrinth. The structure of labyrinth is convenient for defining the North, dividing daytime and defining geographical altitude of the observation point. Orientation in space and time has become the basis for navigation frame of the territory. A set of stone instruments is the key of a navigation frame of the territory. Life-essential stages of the yearly lighting are reflected in specific geometry shapes of shades. They have been preserved in mythological images of the Sun, solar symbols and modern sign systems. Languages, alphabets, numeric systems can be considered as models of geographical space and have evolved thanks to observations of the light movement. Key results of the
