Evaluating productive efficiency : comparative study of commercial banks in Gulf countriesAnouze, Abdel January 2010 (has links)
Financial institutes are an integral part of any modern economy. In the 1970s and 1980s, Gulf Cooperation Council (GCC) countries made significant progress in financial deepening and in building a modern financial infrastructure. This study aims to evaluate the performance (efficiency) of financial institutes (banking sector) in GCC countries. Since, the selected variables include negative data for some banks and positive for others, and the available evaluation methods are not helpful in this case, so we developed a Semi Oriented Radial Model to perform this evaluation. Furthermore, since the SORM evaluation result provides a limited information for any decision maker (bankers, investors, etc.), we proposed a second stage analysis using classification and regression (C&R) method to get further results combining SORM results with other environmental data (Financial, economical and political) to set rules for the efficient banks, hence, the results will be useful for bankers in order to improve their bank performance and to the investors, maximize their returns. Mainly there are two approaches to evaluate the performance of Decision Making Units (DMUs), under each of them there are different methods with different assumptions. Parametric approach is based on the econometric regression theory and nonparametric approach is based on a mathematical linear programming theory. Under the nonparametric approaches, there are two methods: Data Envelopment Analysis (DEA) and Free Disposal Hull (FDH). While there are three methods under the parametric approach: Stochastic Frontier Analysis (SFA); Thick Frontier Analysis (TFA) and Distribution-Free Analysis (DFA). The result shows that DEA and SFA are the most applicable methods in banking sector, but DEA is seem to be most popular between researchers. However DEA as SFA still facing many challenges, one of these challenges is how to deal with negative data, since it requires the assumption that all the input and output values are non-negative, while in many applications negative outputs could appear e.g. losses in contrast with profit. Although there are few developed Models under DEA to deal with negative data but we believe that each of them has it is own limitations, therefore we developed a Semi-Oriented-Radial-Model (SORM) that could handle the negativity issue in DEA. The application result using SORM shows that the overall performance of GCC banking is relatively high (85.6%). Although, the efficiency score is fluctuated over the study period (1998-2007) due to the second Gulf War and to the international financial crisis, but still higher than the efficiency score of their counterpart in other countries. Banks operating in Saudi Arabia seem to be the highest efficient banks followed by UAE, Omani and Bahraini banks, while banks operating in Qatar and Kuwait seem to be the lowest efficient banks; this is because these two countries are the most affected country in the second Gulf War. Also, the result shows that there is no statistical relationship between the operating style (Islamic or Conventional) and bank efficiency. Even though there is no statistical differences due to the operational style, but Islamic bank seem to be more efficient than the Conventional bank, since on average their efficiency score is 86.33% compare to 85.38% for Conventional banks. Furthermore, the Islamic banks seem to be more affected by the political crisis (second Gulf War), whereas Conventional banks seem to be more affected by the financial crisis.

Complex ownership structures, banks' capital structure and performance / Structures actionnariales complexes, structure du capital et performance des banquesZedek, Nadia 29 September 2014 (has links)
Cette thèse examine l’impact de la structure actionnariale sur la structure du capital et la performance des banques commerciales européennes sur la période 2002-2010. Elle est composée de trois essais empiriques. Le premier chapitre teste l'effet de la divergence entre les droits de contrôle et les droits pécuniaires d'un actionnaire ultime sur l’ajustement du ratio du capital à son niveau optimal et sur l’offre de crédit par les banques. Les résultats montrent qu’en présence de divergence entre les droits de contrôle et les droits pécuniaires, les banques n’émettent pas du capital pour augmenter leur ratio et, au contraire, elles réduisent leur taille en ralentissant leur offre de prêts. Le chapitre 2 teste l’effet de cette divergence sur la rentabilité et le risque bancaires en temps normal et en temps de crise. Les résultats montrent que bien qu'une divergence entre les droits de contrôle et les droits pécuniaires soit associée en temps normal à une rentabilité plus faible et un risque plus élevé elle a, à contrario, amélioré la rentabilité et contribué à la résilience des banques pendant la crise financière de 2007-2008. Le troisième chapitre teste si le réseau des actionnaires auquel la banque est liée au sein d’une chaîne de contrôle affecte la relation entre la diversification et la performance. Les résultats montrent que la présence des investisseurs institutionnels dans les chaînes de contrôle aide les banques à tirer des bénéfices lorsqu’elles diversifient leurs activités. / This dissertation examines the role of ownership structure in explaining capital structure and performance of European commercial banks from 2002 to 2010. It comprises three empirical essays. The first chapter explores the effect of greater control rights than cash-flow rights of an ultimate owner on the bank’s capital ratio adjustment and its lending decisions. The results show that whenever control rights exceed cash-flow rights, banks do not issue equity to increase their capital ratio and, instead, downsize by mainly slowing their lending. Chapter 2 provides evidence on how the divergence between control and cash-flow rights affects bank profitability and risk during normal times and distress times. The findings emphasize that during normal times the divergence between control and cash-flow rights is associated with lower profitability and higher risk. Conversely, during the acute financial crisis period (2007-2008), such a divergence improves profitability and banks’ resilience to shocks. The third chapter takes into account differences in the strength of ownership network to which banks belong when assessing the effect of greater activity diversification on bank performance. The results show that diseconomies of diversification vanish the stronger is the ownership network surrounding the bank in the control chain. Such mitigating roles are attributable to the presence of domestic and foreign institutional owners in the pyramid.

Die gebruik van verhoudingsgetalle om kapitaaltoereikendheid van bankinstellings te ontleedBrink, Arend 01 1900 (has links)
Text in Afrikkans / Summaries in English and Afrikaans / The capital-adequacy problem is essentially concerned with the amount of capital that a bank should
maintain in order to conduct its operations in a prudent manner. Because one of the primary
functions of bank capital is to act as a risk cushion for the protection of a bank's depositors, a bank's
capital funds are often regarded as comprising an insurance element. The capital-adequacy concept,
therefore, may be seen as part of the overall banking risk, or prudential management.
An attempt has been made to indicate that bank supervisors should use not only capital ratios when
analysing a bank's capital position. Other factors, such as asset quality and other financial risks,
should also be taken in consideration.
Financial ratio analysis, however, provides bank supervisors with useful information. When
combining ratio analysis with non-quantifiable factors, bank supervisors may indeed achieve their goal
of determining capital adequacy. / Die kapitaaltoereikendheidsprobleem is hoofsaaklik gebaseer op die hoeveelheid kapitaal waaroor 'n
bankinstelling moet beskik, ten einde die bankbesigheid op 'n verstandige wyse te bedryf. Een van
die primere funksies van kapitaal is om te dien as verliesabsorberingsbuffer ter beskerming van 'n
bankinstelling se deposante, en daarom word toereikende kapitaal dikwels geag om 'n soort
versekeringselement te bevat. Die konsep van kapitaaltoereikendheid kan dus beskou word as deel
van die totale risikobestuurskonsep.
Daar is tydens die studie gepoog om aan te dui dat banktoesighouers nie net kapitaalverhoudings
behoort te gebruik om 'n bankinstelling se kapitaalposisie te ontleed nie. Ander faktore, soos
batekwaliteit en antler finansiele risiko's, moet ook in ag geneem word.
Finansiele verhoudingsgetalontledings voorsien banktoesighouers van waardevolle inligting. Indien
verhoudingsgetalle egter met nie-gekwantifiseerde inligting gekombineer sou word, kan
banktoesighouers hul doel om kapitaaltoereikendheid te bepaal, bereik. / M.Com. (Business Management)
