Evaluating cost and profit efficiency: a comparison of parametric and nonparametric methodologies

The objective of this article is 2-fold. First, it provides an empirical assessment of the cost and profit stochastic frontiers based on a panel dataset of Greek commercial banks over the period 1993 to 2005. Second, on the basis of the same sample, it also compares the most widely used parametric and nonparametric techniques to cost efficiency measurement, namely, the Stochastic Frontier Approach and Data EnvelopmentAnalysis. The results suggest greater similarities between the predictions of cost and profit efficiency methods than between parametric and nonparametric techniques. Such evidence is new in the literature and calls for a more technically level playing field for estimating bank efficiency.Bank cost and profit efficiency; Parametric and non-parametric methods

Banking Performance in South-Eastern Europe During the Interwar Period

In the framework of the broader political and economic development of the individual states on Balkan Peninsula the author has made the comparison between the performance of the banking sector in Yugoslavia, Romania, Greece and Bulgaria. The analysis was carried out on the sample of balance sheets for the most important joint stock banking companies in the respective countries in the years 1928 and 1929 which represent the peak of the activity and performance of banks in region. In the following years the whole region sank in the abyss of the Great Depression of the thirties when the issue of banking performance was considered on the different way. One of the common features of the banks in region is certainly the prevailing role of short-term resources and a huge imbalance in interest incomes and incomes from other bank transactions. This fact does not only testify to high margins and effective interest rates, but also to a limited portfolio in bank services and other transactions, which was the consequence of the social and economic environment that banks had to operate in.South-eastern Europe; Banks; Banking; Balance sheets.

The prevalence of credit risk in Greek Banking: Risk management & methodology for evaluating corporate credit risk and Greek Business Environment

Our article consists of the following 4 parts: - In the first part: documented the importance of credit risk with the presentation - analysis of the growth of 6 Greek major financial institutions loan portfolio, for the period 2001 to 2008 and comparison of the loan amount with their own funds and total assets them (based on published accounts). - In the second part: we refer to the approval and monitoring procedures that should be followed by banks using the internal ratings (IRB) methods for corporate loans. Our interest is focused on linking credit ratings to the terms of financing (collateral costs) and on the importance of evaluation / assessment and collateral for the balance of exposures. For typesetting the above is estimated the Risk Weight Assets for PD rating scale (National Bank of Greece published data) and relevant Figure/diagram. - In the third part: we analyse the methodology of key criteria for evaluating the creditworthiness of companies. At the same time for a short description of Greek Business environment we used the -List Easy of Doing Business index 2010- of the World Bank and the results of the assessment of business sectors in Greece according to the model of Credit Risk Tracker Greece's Standard & Poor's, as published by the Hellastat. (The key criteria for evaluating creditworthiness of companies mainly come from research on the websites of the companies Fitch, S & P, Moody's KMV, Hellastat, Easy of Doing Business index). - In fourth part: presented, properly treated, the results of empirical research conducted through distribution of questionnaire to 25 experienced in Risk Management, executives, which was called to assess 20 companies on the basis of their specific quantitative and qualitative characteristics. Finally it is noted that in this final part are also presented all the findings and related conclusions, resulting from the scientific research throughout this paper.

Testing for persistence in mutual fund performance and the ex post verification problem: Evidence from the Greek market

The present study examines a series of performance measures as an attempt to resolve the ex post verification problem. These measures are employed to test the performance persistence hypothesis of domestic equity funds in Greece, during the period 1998-2004. Correctly adjusting for risk factors and documented portfolio strategies explains a significant part of the reported persistence. The intercept of the augmented Carhart regression is proposed as the most appro- priate performance measure. Using this measure, weak evidence for persistence, only before 2001, is documented. The growth of the fund industry, the direction of flows to past winners and the integration in the international nancial system are suggested to be the reasons for the absence of performance persistence

Shareholder wealth effects from mergers and acquisitions in the Greek banking industry

This paper examines the shareholder wealth effects of mergers and acquisitions in the Greek banking industry from 1995 to 2001, using the “event study methodology”. The results suggest that targets’ shareholders earned significant abnormal returns upon the announcement of horizontal and diversifying deals. On the other hand, bidders’ shareholders had significant losses in cases of horizontal and zero effects in diversifying deals. Although mergers and acquisitions in the Greek banking industry are not found to be value-enhancing, they can be rationalized as an external growth strategy, whose goal was to strengthen the position of the participants in the domestic market and help them become more tenacious in a fiercely competitive international environment.Mergers and Acquisitions; Banking; Valuation effects

Cost Efficiency in Greek Banking

TThis study uses the distribution free approach to investigate cost efficiency in a panel of Greek banks over 1993-1999, a period characterized by major changes in the banking sector brought about by gradual financial deregulation. These reforms were supposed to provide an opportunity to Greek banks to improve their efficiency and to enhance their competitiveness in view of ongoing financial integration in Europe and the introduction of the euro. The results obtained indicate that important cost X-inefficiencies are in place. Some evidence is provided that bank characteristics such as bank size, type of ownership and risk behaviour do play a role in explaining differences in measured inefficiencies. Scale economies are also examined and the findings indicate that the Greek banking industry experiences economies of scale, though they have declined throughout the observed period. This suggests that competitive viability may be an important factor for further consolidation in the Greek banking industry.X-efficiency, scale economies, panel data

Disentangling Within- and Between-Country Efficiency Differences of Bank Branches

In this paper we propose a framework to assess the efficiency of bank branch networks operating in different financial environments. The framework can be used to disentangle within- from between-country performance differences. The framework is constructive in that it identifies operational aspects responsible for superior performance and suggests guidelines for branch improvement. We report results from three bank branch networks in the U.K., Greece and Cyprus, and demonstrate how branch networks can benefit from such international comparisons.Bank Branch Efficiency, International Benchmarks, Data Envelopment Analysis.

Strategic decision-making process (SDMP) in times of crisis:evidence from Greek banks

This paper investigates the strategic decision making process (SDMP) of Greek banks’ top management in the context of profound organisational changes introduced in 2012 due to the aftermath of the 2008 global financial crisis. It focuses on the impact of three key dimensions of the SDMP, namely, rationality, intuition and political behaviour, relating to four changes introduced, namely, mergers and acquisitions, branch network rationalisation, integration of information technology (IT) and downsizing of operations and personnel. A survey questionnaire was conducted, targeting Greek banks’ top management. Out of 140 questionnaires, 78 were returned, a 55.71% response rate. Data was analysed using structural equation modelling. Research findings identify rationality as a key dimension of SDMP for all organisational changes, as there was high focus on identifying and analysing all required information, use of external financial advisors, and reliance on multiple methods of information gathering. Decision-makers used their intuition in the form of past experience when making acquisition decisions, whilst their personal judgment and “inner voice” were neglected.Finally, political behaviour was not displayed during this process, as decision-makers were open with each other about their interests and preferences, and there was no bargaining, negotiation or use of power amongst them. One limitation was that of not considering all the factors that might help measure SDMP. Also, this study was conducted in a period of political and financial uncertainty for Greek banks, as well as for the Greek economy in general, so findings may not be generalizable to other industries and countries. Conducting interviews could have offered deeper insight as well. This study’s value lies in the fact that the organisational changes were determined by Greece’s leaders, and thus the Greek banks had to operate under a dynamic, inflexible and non-autonomous environment. Also, this study extends prior SDMP research by examining the impact of the three key SDMP dimensions on four types of organisational change
