Loulid, Hanane. "Analyse comportementale du risque de crédit : cas du Crédit Immobilier Général." Thesis, Paris Est, 2010. http://www.theses.fr/2010PEST3014.
Full textThis thesis focuses on the assessment of credit risk with a behavioral approach in a context of asymmetric information and bounded rationality. We seek through this analysis, to reconcile the "business experts" and statisticians, incorporating human behavior into the design of tools for quantitative assessment of credit risk in order to optimize the management of this risk.The assessment of credit risk is based on models and statistical techniques more advanced. We cite as examples of models JP Morgan Credit Metrics, model and KMV's Portfolio Credit Model Mekinsey or scoring models introduced to assess the quality of the risk of borrowers. Several studies underline the importance of these quantitative models. Indeed, Scot FRAME and AL showed that the use of scoring models is effective in reducing the cost of information in large U.S. banks. The results of these models depend on the realization of the risk factors specific to each borrower and systemic risk factors. However, the current financial crisis has highlighted the failure of these models, both theoretical models that rating business models used by practitioners in assessing credit risk. All these constructions have not been able to integrate fully all the information and treat the complexity of interactions between variables determining the risk because they are based on purely statisti cal techniques who can represent the linear relationships between risk default and the variables that are at the origin without taking into account the behavior of credit risk manager, in optimizing its management.Given the limitations of the quantitative approach, we have converged on a behavioural approach that combines statistical techniques and human behaviour based on consideration and validation of collective decision rules emerging from the discussions and confrontations. This behavioural approach that takes into account the rationality of decision makers through an expert model we will firstly build a normative framework for analysis to identify and assess credit risk and also integrate these rules systems in operational decisions.Our research has a substantial multiple. It sheds light on the theoretical optimization of the decision of the banks in a context of uncertainty through a model bearing both on the quantitative assessment models of credit risk and human behavior. The assessment of credit risk through our approach will also determine the amount of capital necessary to cover credit risk. Thus, it will allow banks to establish an optimal allocation of capital and adequate pricing of loans based on an accurate assessment of credit risk. This brings great interest to banks and customers too

Full textThe purpose of the present thesis is twofold. The first is to identify the new legitimacy of the credit cooperative institutions within the modem economy. The second is to work out an analytical framework for the study of credit cooperatives. Credit cooperatives today have become major banking institutions in many countries. However, since the beginning of 1980s they have undergone tremendous changes in their internal organization and external environment due to the recent transformations of the world financial system. Under the pressure of these changes and growing critics about their organizational and economic inefficiency, credit cooperatives face new complex alternatives : either to maintain their cooperative structure thus limiting the scope of their activities and taking the risk of gradual extinction; or to integrate into the market system, thus accepting the rule of so called "financial technicians" and the possibility of their demutualization. However, according to our hypothesis, in spite of ail these changes, cooperative credit is not yet outdated and it still plays an important role in the banking sector. Consequently, we believe that the cooperative credit institutions can still be differentiated from commercial banks not only by their organizational structure but also by their banking activities properly speaking. This fundamental difference is crucial since it explains their complementary role in the banking sector along with the commercial banks and other financial institutions. Our main task consists in analyzing the economic role and significance of credit cooperatives in various countries in order to identify their main common features and to justify their existence and utility. We also present a new analytical model specifically elaborated for the study of organizations which have a cooperative structure and credit function

Full textIn this thesis we study the impact of informational problems on economic agents' behaviour in the french case. The basic idea is that, due to informational problems, external financing is an imperfect substitute to internal financing. Any shock to this external financing premium is immediately transmitted and amplified. This thesis aims to answer to the question of the existence of a credit channel in France by using french individual data. After a survey of the existing literature we model the behaviour of a borrowing firm. We consider different cases : no informational problem between the firm and the bank, informational asymmetry between the firm and the bank (this is the large credit channel case), problems of refinancing for the bank (this is the strict credit channel case where the bank's financing conditions impact on the firm's investment behaviour). This three-floors model is the reference scheme for our econometric estimations. We firstly use data from the Banque de France on banks' refinancing conditions. The estimations done lead to reject the existence of a strict credit channel in France. We then examine data from the Banque de France on the credit cost. The data show that the spread between the borrowing rates on different amounts rises when the refinancing rate decreases. We explain such a behaviour with a credit channel interpretation : when the refinancing rate decreases, firms that were too risky to borrow until now, are allowed to enter the credit market and this effect exceeds to overall interst rates decrease. Our estimations confirm this phenomenon. This is in line with the existence of a large credit channel in France

Full textSovereign debt is a powerful instrument of the public policy. With its dramatic increase in the western economies, on the one hand, and the fundamental change of its structure in the emerging markets, on the other, understanding the determinants of the sovereign default risk has became a subject of major concern for both researchers and investors. This dissertation investigates aspects of sovereign default risk in advanced and emerging economies.The theoretical section explores the sovereign default risk. The main results show that the choice of the currency of issue represents an important aspect of the sovereign's risk profile.Three empirical studies have been conducted. In the first, a detailed analysis of the sovereign defaults using a new database which includes 100 countries observed over the period 1966-2012 has been conducted. The results show that sovereigns typically default under different economic and financial conditions depending on the bond's currency denomination and the investor's base.The key contribution of the second research is to assess the importance of the currency of issuance in the rating of sovereign debt. The study demonstrates that countries whose debt is largely - or entirely - denominated in their own currency enjoy a substantial advantage over government issuing debt in foreign currency.The last empirical section explores the market price ofs overeign risk. It arugues that the default probability on sovereign bonds is unrelated to global factors.The main results imply that any sovereign default risk modeling requires a distinction between local currency and foreign currency

Full textWe analyse credit availability in order to evaluate the impact of a capital crunch and monetary shocks on agreggate investment. We show that the heterogeneity of lenders (in terms of capital and expertise) and borrowers (in terms of wealth) explains the asymetrical transmission of exogenous shocks on economic activity. In a model of endogeneous credit allocation, we show that imperfect substitutability between the different sources of external funds explains firms' optimal choice of financing: investors finance large firms wheareas large (small) banks finance medium (small) firms. A negative monetary shock leads to a contraction in investment and to a flight to quality effect. We stress that a shock on the capital of small banks leads to a contraction of credit and total investment higher than a shock of the same length on the capital of large banks. Thus, there are exclusively small bank dependent firms

Full textIn the aftermath of the 2007-2009 crisis, several studies led by the Base! Committee showed a large dispersion of risk-weighted assets (RWA) among banks, a significant part of which would come from the internal model's assumptions. Consequently, new regulations aiming at finding a balance between risk sensitivity, simplicity and comparability have then been developed. These ones notably include constraints on models / parameters for the internal assessment of the credit RWA for both the banking and the trading books. ln this context, the thesis work mainly consists in analyzing the relevance of such constraints to reduce the RWA variability. It makes extensive use of sensitivity analysis methods, particularly the ones based on the Hoeffding's decomposition. Regulatory treatments of the credit parameters (default correlations, default probabilities -DP -and loss given default -LGD) form the backbone of the developments. The findings suggest mixed results of the reforms. On the one hand, the constraints on the correlations for the trading book have a low impact on the RWA variability. On the other hand, the constraints on OP and LGD parameters, having a greater impact on the RWA variability, should be considered with more caution. The studies finally provide evidence that variability is amplified by the regulatory measurement of the risk and the multiple sources of calibration data.javascript:nouvelleZone('abstract');_ajtAbstract('abstract')

Full textFrom the general hypothesis that the rural sector can mobilise internal financial resources through savings to support its development, this thesis analyses the functioning and assess performances of the rural saving system of cameroon, using the west province as a case study. A field survey was carried, and followed by both quantitative and qualitative analysis to assess saving behaviour of rural populations and understand the institutional setting of the saving collection system, in order to determine its performances. The study of individual saving behaviour, using a socieconomic approach shows that there is a broad diversity in saving practices recorded, but they can be classified into savings in kind and savings in cash. The results obtained also show that economic factors, including interest rate play a limited role as saving determinants. They are overwhelmed by social factors which appear to be more important than expected. Savers attach a great importance to the security of their savings, which are mainly used to finance investment projects. The saving system was then divides into three components : informal, semi-formal and formal for analytical purposes. A performance evaluation matrix was designed, using both social and economic criteria, and combining quantitative and qualitative analyses. Its application to the saving collection system shows a sizeable disparity among the various components. The major conclusion is that despite its limitations, the rural saving system can mobilise enough funds for appropriate funding of the rural sector, provided some adjustments are made, including state intervention to secure adequate funding for agriculture and to preserve food security in the country

Full textThe purpose of this thesis is to contribute to the understanding of the carbon price quota structure, the analysis of its fluctuation, and the interactions that may exist between on the one hand the EU system of emission quota exchange (ETS) and the mechanism for clean development (CDM) and on the other hand between carbon quota market and the quota in the energy sector. For this study, we introduced the hypothesis of heterogeneity of agents' behavior on the carbon market where coexist multiple scales of investments.To achieve this, we used a time-frequency approach (wavelets) that can analyze the local behavior of a signal by isolating the components related to the agents’ trading frequency. This method allows variance decomposition of a time series into different frequency components. The time investment horizons are assigned to each frequency band associated with a degree of market risk. High frequency bands obtained by wavelet decomposition contain information pertaining to the short-term time series structure; the medium and the low frequencies respectively capture the structures of the time series in the medium and long term.To complete this project we proposed developing of our research in 3 chapters:The first chapter presents the carbon market, its creation, its operation, and the various actors who animate it. The formation of the CO2 price, its evolution and its determinants were also analyzed during this chapter.The second chapter develops a multi-scale analysis of the co-movement between price of quota (ETS) and carbon credit (CDM). This particular study was based on two assumptions:- The first assumption was the homogeneity of the various agents’ behaviors. The co-movement relationship between the price of quota (ETS) and carbon credit (CDM) assumes that market participants have the same investment strategy especially since all stakeholders agents invest in these markets on the same horizons. This relationship is studied using standard econometric tools such as Analysis of Co-integration of causality and Vector Autoregressive modeling.The main result of this specific part highlights the existence of a unidirectional causality from the ERC to the EUA with an observed acceleration of the mechanism for clean development (CDM). Manufacturers have a strong interest in the CDM which has had a direct impact on the price of EUAs on the European carbon market. We also observed a dynamic interconnection through the VAR (1) between EUA and CER.- The second assumption is the heterogeneity of agents' behavior. We highlighted the relationship of co-movement between price of quota (ETS) and carbon credit (CDM) to a multi-scale analysis derived from wavelet theory. We show that whatever the different investment horizons retained (short, medium and long term), there is a significant positive relationship between the two sets of prices. The more dynamic causal wavelet on each pair of frequency bands detects an unstable relationship between EUA and CER which confirms our working hypothesis.And finally, a third chapter that complements the previous analysis by the co-movement between multi-scale carbon allowance prices resulting from the ETS to those energy markets (oil, coal and gas). Using coherence wavelet, it examined the simultaneous dependence (co-movement) between two price series in time and frequency. It can be interpreted as a local measurement of correlation calculated non-parametrically. Overall, this study is the first attempt at a multi-scale analysis of the co-movement relationship between the CO2 market, Oil, Gas and Coal which is based on the hypothesis of heterogeneity of agents using a template from wavelet algorithm. The model used in this study will allow stakeholders agents on the carbon market to have a great range of choices for their strategies to be able to anticipate wisely because of the high volatility of carbon prices on their different investment horizons

They point out also that this effect can be equally attributed to the gain of transparency occasioned by the IFRS but also to the selective and conservative approach of the French Central Bank Credit Methodology

Full textThis thesis contributes to analyze the extent to which financial cooperatives contribute to povertyreduction. From this point of view, our analysis focused on both the adequacy of the conceptualframework of these institutions and their impact on members. As for their operation, our analysis showsin the case of Benin that cooperative principles generally applied. However, they face problems offinancial sustainability and governance related to the growth of membership.With regard to their impact on shareholders, our results suggest that in the short term, the integratednature of these institutions has proven globally relevant. As for the financial dimension, it appears fromthe results that the community loan contributes positively to the growth of household income, theincrease of investment in human capital for children through higher education and health spending, butwith a relatively small range. However, the community loan had no effect on the growth of savings. As forthe non-Financial dimension, our results suggest that non-Financial services offered exercise through thestakeholder-Status, a positive influence on the formation of the income of households that arebeneficiaries of the cooperative loan.In the same vein, in terms of economic mobility, our results suggest, in short-Term a relatively lowmobility of recipient households which is also related to the initial state of well-Being. In other words, thefrequency of mobility is upward for all states of welfare for all recipients, except for the poorestshareholder households. Compared to non-Beneficiaries, our results suggest in some ways, a high upwardmobility for beneficiary households. Over a longer term, our results suggest a very slow convergence ofmembers to a state of higher well-Being when the cooperatives are not subject to change in their povertyreduction strategies.In addition, the analysis of the influence of the degree of credit constraints revealed by the shareholderswho were beneficiaries of the community loan, shows that the existence of credit constraints in the supplyside does not seem to have influenced the living standards of beneficiaries who rated the value of the loanreceived as "insufficient" or "very insufficient" in the short term. But, compared to recipients who foundthe value of the loan received "sufficient", our results suggest at first, the existence of a selection bias andin a second step, the chance to escape poverty is lower for this category of beneficiaries compared to therest of the population with the same characteristics but who feel very constrained ("loan received is veryinsufficient") or partially constrained ("loan received is insufficient".)In total, our results highlight that the integrated nature of cooperatives can contribute to economic growthand improve the welfare of poor and vulnerable members, provided that these cooperatives clearly definea strategy in that direction and spread it over a defined period of time. In addition, to achieve this, theseinstitutions need to be supported by external grants or other complementary programs, when oneconsiders their endogenous mode of resource mobilization

Full textWe show that the bank lending channel can generate several regimes in the transmission process. It may either amplify or attenuate the effectiveness of monetary policy. On certain conditions, the direction of change in the spread between a loan rate and a riskless rate, a proxy of the monetary policy rate, contains a useful information for distinguishing different regimes. Empirically, we explain the effectiveness of monetary policy in Poland in the 90s. The weakness of monetary policy impulses between 1994 and 1999 results from a fixed exchange rate system, an attenuation regime and a demand-driven disequilibrium in the loan market. The existence of a stronger transmission since 1999 is linked to the adoption of a floating exchange rate system, the appearance of a neutrality regime and a supply-driven disequilibrium in the loan market

Full textWe define secondary market of less developing countries (ldc) as a transaction space of bank credit grant to sovereign nations. The object of this thesis is to analyze how this market works and understanding determinants of secondary market debt prices. We study the international economic and financial framework in which euro-credit boom took place. We also study analysis of country-risk. Thus, we can draw the origins of secondary market debt. Then, we answer to the questions : who, how and why operate on this market. Initialy, secondary market debt was a subcontracting market, exclusively interbank and dominated by subparticipations. In the 1980s, debt crisis alter his physiognomy. Debt-debt swaps take over from subparticipations. Market debt open to new party, in particuler to multinational firms, as mods of intervention increase (assignements, debt-equity swaps). Market value of credit sovereign bank, in period of debt crisi and renegociation is also analyze. We question about use of traditional actural techniques to estimate market value of this kind of bonds, and decote is define as a synthetic expression of subjective banks anticipations of defaul payments. We study debtor countries according to the level and the evolution of market debt prices. Theorics and econometrics works about determinants of market prices are presented and discussed. Taking into account strategic (opportunist) behaviour on the market seems to be an interesting future way of research

Full textConsumer credit outstanding stands at 7 or 8 per cent of the GDP. The regulation frame of consumption credit was profoundly modified by the Consumer credit directive 2008/48/CE and the « Lagarde Law » n°2010-737. Consequently, the question we address in this research is: what type of relationship exists between lenders and borrowers in consumer credit market? Are these relations specific? Three objectives are proposed. In any case, we present a lender position and a borrower position. The first one, linked to regulation evolutions, shows that information is the cornerstone of such a relation and any information impacting it. The second objective, more strategic, shows those behavioral biases considerations (overconfidence and optimism bias) or the elaboration of a long run relationship banking between lenders and borrowers impacts on the decisions of granting credit. The third objective, more financial, shows that this relationship defines “optimal” ways of household's indebtedness and also reduces the loan portfolio risk of a lender. A methodology both qualitative and quantitative is used. It is shown that the equilibrium is a pooling equilibrium and that the relationship banking indirectly impacts the consumer credit market. A composition involving a behavior bias yields a less risked loan portfolio for the lenders. The lender borrower relationship is analyzed from the information sharing systems in the 27 EU countries

Full textThis thesis focuses on two parts: providing theoretical understanding and investigation of technical efficiency score in Islamic and conventional banks. This study is divided into two parts. In the first part, the study provides useful theoretical illustrations regarding the comparison between conventional banks and Islamic banks in greater details, covering the difference in banking scheme, organization structure, money creation, balance sheet structure, the function of a central bank, and the difference on impact to economic system and economic cycles. The second part is the calculation of technical efficiency score to understand how the distribution of score across banks under three primary assumptions: Constant Return to Scale, Variable return to Scale and Scale Efficiency. The second part involves regression analysis in understanding financial variables affecting technical efficiency and how different the score between Islamic and conventional banks. The sample of this study is 1,425 commercial banks and 85 Islamic banks (Data downloaded from Bankscope Database). The method used in the first part is Data Envelopment Analysis and Descriptive Analysis, while the method used in the second part is Tobit regression. The findings in this study shows that Scale Efficiency score is better to represent efficiency score compared to Variable Return to Scale and Constant Return to Scale. The study also shows that Islamic banks are statistically more efficient than conventional banks. Moreover, the study found that return on average asset, net loan to total asset ratio, net interest margin, and equity to total asset ratio significantly affect the efficiency score

First of all, good practices that are based on the financial theory have been identified. Also, real practices have been explored from an evaluation of some real cases consisting in indebted dairy farms in operation for many years. Results demonstrate that, for the sample of farms subjected to special conditions, some cases present practices that are not strict enough. Furthermore, behavior study and risk evaluation of the farmers in regards to the bank credit bring to conclude that the situation is not going to improve easily if there is no future change. So, it is demonstrated that funding practices can be a factor that explains why some results of the indebted dairy farms are not attractive.

Full textThis thesis analyses, trough a case study, the operation of a rural micro-credit program implemented by Plan international NGO. It has then been changed into a formal institution and integrated into one of the largest network of mutual organizations in Senegal: UMPAMECAS. Our objective was to show how micro-finance organizations reconcile social and financial logics that are primarily contradictory, in their action after institutional changes. Considering the diversity of rules and operation modes observed in the institutions under scrutiny, we have mobilized the convention economy to build the framework of our analysis. The thesis is based on a diachronic quantitative analysis of those logics to understand what underlies them, power mechanism and stakes that make them evolve and stabilize. For a period from 2006 through 2008, we surveyed 169 people from different (wages-earners, elected, credits beneficiaries, etc.). This work has cast light on the transformation process of rural microfinance and its stakes. We have shown that, thanks to a methodology combining several principles from different cities, but essentially related to a “social logic”, the first generation of microfinance institutions have enabled several people living in rural areas, whose economic profile did not appeal to commercial banks, to get access to financial services. The institutional transformations induced by endogenous and exogenous facts have brought changes which should be dealt with by the institutions to ensure their sustainability. Our research has shown that to survive the transition and avoid conflicts, consultations should be conducted all through the process with all the stakeholders for all to agree on the objective of the transition, the way the process should be conducted and the reforms that need to be implemented. Besides, the newly implemented procedures should match local specificities. Furthermore, this thesis has shown the supremacy of the “tontine” systems (rotating saving and credit associations). Those systems have deeply evolved and enriched due to the hybridization of commercial, domestic and civic rules that make them today local organizations that strongly challenge formal structures in the collecting of savings

Full textWhy don't Camerouun rural households refer to microfinance institutions for their financial services needs ? Why are social exprenses so important in their budget ? These questions are relevant to the atypic financial behavior of rural households, as regarding the microfinance and rural development actions. They suggested this thesis on rural financial behavior, and the demand side approach based on households personal characteristics. The objective is to show the rationality underlying their financial choices. Based on the househoulds economic portofolio model, empirical analysis to characterize households was developped, then a theoretical analysis to explain the observed behavior was conducted. The results are sumarized in five main points : 1 - households are rational in the sense of "Homo Africanus" ; 2 - their level of education and existence of secondary activities, together with social objectives to meet their basic needs, act to motivate and interest in financial institutions ; 3 - general poverty and precarity exclude many households from financial institutions, depending however on educational level, activities, size of household and sex, women are worst off ; 4 - the demand for savings, insurance, specific production and social needs'credit is not covered by local informal structures, leaving rural households in "financial disarray" ; 5 - very few rural people have knowledge on microfinance institutions, the later are more located in urban areas where their clients allow for higher returns.

The thesis comes to the conclusion that low financial deepending and households'personal characteristics are the reasons why supply and demand for financial services seldom meet

These have chosen to conduct policies aiming at price stability essentially through the control of the money supply in order to guarantee a steady and durable growth. Through a three case study (France, Great-Britain, United-States), the relevance of these objectives will be tested by identifying which instruments are at the monetary authorities' disposal to control the monetary creation and if they hold such a power. Besides, the validity of the monetary aggregates intermediate target is based on a relationship between money and prices which will be necessary to enlighten. Finally, is the price stability set by the final goal enough to ensure a sustained growth ?

Full textGiven the share of the residential sector in households' energy consumption, residential energy retrofitting is a burning issue in the climate change policy strategy. All the investment barriers faced by households invite us to explore the investment factors and to assess the efficiency of public policies. In a first part, the thesis studies the investment factors by estimating a discrete choice model on data from the French annual "Energy Management" survey conducted by Ademe, particularly focusing on factors heterogeneity among retrofitting types. A second part of the thesis deals with the assessment of public policy promoting energy efficiency, both from the demand and the supply sides of the energy efficiency markets. Regarding the demand side, the thesis uses two complementary methods: an ex-post econometric study focuses on the French tax credit called Credit d'lmpot Developpement Durable implemented in 2005 while an ex-ante study uses a hybrid energy-economy model to compare different policies. Regarding the supply side, given the high degree of concentration on the energy efficiency markets, we use a theoretical model to assess public policy efficiency in the presence of three markets imperfections: the negative externality linked to C02 and the imperfections of market competition and information inducing price-quality discrimination

Full textThe goal of this thesis is to explore the implications for corporate finance of the rising importance of intangible capital in shaping firm’s growth and competitive edge. In the first chapter (with C. Lenoir from CREST), we look at the role of liquidity constraints in the accumulation of customer capital. We show that both financing and product market frictions lead firms to under-invest in customer capital. In the second chapter (with T. Libert from PSE and C. Hurlin from U. of Orléans), we study the implications of the under-diversification of the borrower base of banks. We find that it exposes lenders to considerable borrower idiosyncratic risk and leads credit variations to be more synchronized across banks. In the third chapter (with V. Lyonnet from OSU and C. Hebert from Paris Dauphine/Tilburg U.), we study how human capital shape firms’ boundaries. Our results suggest that firms use M&As as a way to acquire specialized human capital when external hiring is too costly

A legislação sobre as atividades dos bancos de desenvolvimento determina que os mesmos conciliem aspectos da análise de projetos com a análise de crédito nas decisões relativas à concessão de empréstimos. Em outras palavras, busca-se não somente analisar a rentabilidade do empreendimento, mas também levantar a capacidade de pagamento da empresa. Visando verificar a operacionalização destes critérios foi feita uma pesquisa em uma amostra destes bancos. A pesquisa mostrou que as metodologias de análise de projetos têm sido baseadas na análise de crédito, sem considerar a rentabilidade do empreendimento. Além disso, o BNDES, instituição que fornece a maior parte dos recursos dos bancos de desenvolvimento, determinou que sejam aprovados exclusivamente projetos competitivos. Como as metodologias pesquisadas demontraram que esses bancos não têm atribuído a devida atenção à determinação da capacidade competitiva da empresa e do projeto analisado, foi elaborado um modelo de análise de projetos incluindo indicadores que procuram apurar o fator competitividade nas operações de financiamento. O modelo traz outras contribuições, tais como: estruturação na forma de rattings, inclusão de indicadores sobre o rendimento do projeto, e sobre os reflexos no portfólio de negócios do grupo.

Full textIn finance, model risk is the risk of loss resulting from using models. It is a complex risk which recover many different situations, and especially estimation risk and risk of model misspecification. This thesis focuses: on model risk inherent in yield and credit curve construction methods and the analysis of the consistency of Sobol indices with respect to stochastic ordering of model parameters. it is divided into three chapters. Chapter 1 focuses on model risk embedded in yield and credit curve construction methods. We analyse in particular the uncertainty associated to the construction of yield curves or credit curves. In this context, we derive arbitrage-free bounds for discount factor and survival probability at the most liquid maturities. In Chapter 2 of this thesis, we quantify the impact of parameter risk through global sensitivity analysis and stochastic orders theory. We analyse in particular how Sobol indices are transformed further to an increase of parameter uncertainty with respect to the dispersive or excess wealth orders. Chapter 3 of the thesis focuses on contrast quantile index. We link this latter with the risk measure CTE and then we analyse on the other side, in which circumstances an increase of a parameter uncertainty in the sense of dispersive or excess wealth orders implies and increase of contrast quantile index. We propose finally an estimation procedure for this index. We prove under some conditions that our estimator is consistent and asymptotically normal

Full textAs cooperativas de crédito são regidas pelos mesmos princípios cooperativistas, mas agregam funções financeiras como os bancos tradicionais. A solidariedade na área financeira permite que as cooperativas de crédito levem aos seus cooperados os fundos poupados ou repassando os de desenvolvimento governamental das políticas públicas em forma de crédito. É evidente, no entanto, que nem sempre os “apoios” são devolvidos da mesma maneira como foram recebidos, neste mundo de muita perfeição e de alta competitividade. Assim, integra o elemento estranho no meio onde se imagina seu difícil acesso, a falta de confiança no cumprimento do contrato de crédito contraído pelos credores (cooperados). É conhecido como Risco de Crédito ou de um eventual não pagamento das dívidas contraídas pelos cooperados, o principal fator para processo de Gestão de Risco de Crédito nas instituições cooperativas do mundo. Desse modo, se insere o problema da pesquisa, sendo nova a gestão de risco nas cooperativas de crédito e num mercado assombrado pelas crises financeiras, e com isso se questiona: em que medida ou em que ponto o cumprimento das normas da gestão de risco de crédito nessas instituições vem sendo atendido? Com base nessa preocupação, traçaram-se os objetivos, que apontam em avaliar as práticas de gestão de risco em cooperativas de crédito do Sudoeste do Paraná (PR) de acordo com as resoluções do Conselho Monetário Nacional (CMN). Para isso, tem-se como objetivos específicos: listar as práticas de gestão de risco necessárias para a concessão de crédito; identificar de que forma estão sendo abordadas as práticas de gestão de risco de crédito, considerando-se normas de CMN; verificar qual é o impacto da gestão de risco percebido pelos gestores nas cooperativas de crédito; levantar em termos quantitativos quanto essas cooperativas perdem anualmente em inadimplência (default); comparar as práticas das cooperativas pesquisadas entre si e com as resoluções do CMN. O trabalho se justifica pela importância do processo de gestão de risco para as instituições cooperativas, para a academia e pela contribuição no reforço àquilo que o CMN vem recomendado nas suas resoluções. Para se atingir os resultados pretendidos, foi aplicado um estudo de caso múltiplo nas cooperativas CRESOL, SICOOB e SICREDI/PR, com abordagem qualitativa e quantitativa, em parte com dados secundários e primários. Os dados secundários foram levantados por meio da revisão da literatura referente às áreas de cooperativismo em geral e de crédito, a gestão de risco de crédito e normas e as resoluções do CMN sobre o tema, além de informações nos Relatórios Financeiros das três cooperativas. Os dados primários foram levantados por meio de aplicação de questionário nessas instituições, sendo entrevistados os Gerentes de Crédito, o Assessor Sênior da Controladoria e o Assessor e Supervisor de Crédito. Os dados levantados foram comparados entre as informações dos entrevistados da mesma instituição e depois com as outras, sendo que, na análise dos dados, os nomes das mesmas (instituições) deixaram de ser citadas e foi atribuído o nome de CASO (CASO1, CASO2, e 3 ). Foi identificada uma preocupação com a gestão de risco nessas instituições. Também se percebeu que o crédito só é liberado quando passa por análise de, no mínimo, três pessoas. Existem procedimentos de análise de crédito que seguem todas as alçadas necessárias para que a proposta seja deferida e também são avaliados de acordo com a renda do proponente e as cooperativas singulares são classificadas de acordo com seus patrimônios de Referências (PR) e Patrimônios de Referências exigidas (PRE), para receberem crédito das suas centrais e até para liberarem crédito aos seus cooperados Pessoa Jurídica, caso existam. Mesmo assim, foram localizadas as perdas (prejuízos), algumas mais acentuadas do que outras. Percebe-se que ainda existem reduzidos estudos sobre gestão de risco nas cooperativas de crédito, dada à situação em que se encontravam as mesmas, mas atualmente vale reforçar as pesquisas para conhecer como essas instituições lidam com a gestão de risco de crédito e outros riscos.
Credit unions are governed by the same cooperative principles but add financial functions as traditional banks. Solidarity in the financial area allows credit unions to take to their members or transferring funds spared government development of public policy in the form of credit. But it is not always clear that the "support" are returned the same way they were received, in this world of too much perfection and high competitiveness. Integrates the foreign element in the middle where you think its difficult access, lack of confidence in the fulfillment of the credit agreement contracted by creditors (cooperative). Known as credit risk or a possible non-payment of debts contracted by the cooperatives the main factor for Credit Risk Management process in cooperative institutions in the world. Thus falls the research problem, and new risk management in credit unions and a market haunted by financial crises, and if it asks: To what extent or at what point the compliance of the management of credit risk these institutions has been met? Based on this concern were traced objectives, which aim to assess the practices of risk management in credit unions Southwest of Paraná (PR) according to the resolutions of the National Monetary Council (CMN). For this, one has the following specific objectives: List the risk management practices needed to grant credit; Identify how they are being addressed management practices of credit risk considering CMN standard; Ascertain the impact of the management of risk perceived by managers in credit unions; Rise in quantitative terms as these cooperatives lost annually in default; Compare practices of cooperatives surveyed each other and with the resolutions of the CMN. The work is justified by the importance of the risk management process for cooperative institutions, academia and the contribution to the reinforcement to what the CMN has been recommended in its resolutions. And to achieve the desired results a study of multiple case was applied in cooperative CRESOL, SICOOB and SICREDI / PR, with qualitative and quantitative approach in part with secondary and primary data. The secondary data were collected by reviewing the literature pertaining to the areas of cooperative movement in general and credit risk management and credit standards and CMN resolutions on the topic, also collected in the Financial Reports of the three Credit unions. Primary data were collected through a questionnaire in these institutions, being interviewed Managers of Credit, Senior Advisor of the Comptroller, Assessor and Supervisor of Credit. And the data obtained were compared to the information of the respondents from the same institution and then with the other, in the data analysis of the same names (institutions) are no longer quoted and was assigned the name of CASE (case1 case2 and 3). A concern with risk management in these institutions was identified. Also noticed that credit is only been released when passing by analysis of at least three people. There are procedures for credit analysis that follows all the necessary limits for the proposal to be granted and are evaluated according to the income of the applicant and the individual cooperatives are classified according to their Wealth of References (PR in Portuguese) and Heritage References Required (PRE in Portuguese), to receive credit of their plants and up to release credit to their members Corporations if any. Yet losses were located some steeper others do not. Realize that there are still smaller studies on risk management in credit unions, given the situation they were in the same, but is currently worth strengthen research to know how these institutions deal with the management of credit risk and other risks.

Full textThis work presents a methodology for credit risk prediction, comparing the performance of three statistical techniques used in the prediction process: discriminant analysis, logistic regression and neural networks. The proposed method (entitled PRC Model) embraces six steps: (i) population definition, (ii) sampling, (iii) preliminary analysis, (iv) model development, (v) model selection and (vi) implementation steps. The PRC Model was applied to a sample of 17,005 customers from an organization, which manages his own credit system and controls a pool of drugstores. The results show the superiority of neural networks over the other two techniques. This was expected due to the non-linear approach of the neural network when dealing with the explanatory variables. Considering the neural network model and the annual sales due to customers included on this study, the use of the proposed methodology indicates a 65% potential profits.

Full textThis research deals with the credit limit stipulation for corporate clients, automatically, with the use of Computational Intelligence techniques, specifically artificial neural networks (ANN). In the analysis of credit, the two most critical situations are release of credit, according to the customer profile, and maintain the credit according to the customer history. The object of this work aims at automating the stipulated credit limit at the time of initial registration of the customer. The main focus of this work is to make an ANN can provide the credit limit, learning from situations that have occurred with other clients of similar profile and is able to make decisions based on the credit policy seized with a Credit Analyst. The goal is to make the system more secure credit to the lender, for a correct analysis of the creditworthiness of a customer drops considerably default rates and maintains a sales plateau great. For this analysis, we used the VB.Net programming language for the registration system of MatLab and was used for training ANNs. The paper presents a case study, which shows how to apply this software to credit analysis. The results obtained applying the techniques ANNs were satisfactory showing an efficient way to determine the credit limit.

In the last two decades due to expansion of the credit market, it became necessary to develop risk classification models that not only capture the probability of default, but also when" is the time of default. This study investigated the probability of default is affected by general economic conditions over time due to the use of Survival Analysis technique. Using data from credit card holders of a financial bank the objective was to analyze potential influences of variables of record, register and macroeconomic variables on survival time, it means, not default. The results suggest that models incorporating macroeconomic factors allow the improvement of the explanation of survival time compared to models that utilize only data register/records. Considering records/registers variables, statistical tests showed that females had higher survival, indicating that men tend to go into default earlier in the studied sample. Regarding the macroeconomic variables, the level of monthly unemployment has more relevance in explaining default.
Nas duas últimas décadas, devido à expansão do mercado de crédito, tornou-se necessário o desenvolvimento de modelos de classificação de risco que não somente capturassem a probabilidade de inadimplência, mas que estimassem quando ocorreria o momento de default. Este estudo investiga se a probabilidade de default é afetada pelas condições gerais da economia ao longo do tempo, utilizando a técnica de Análise de Sobrevivência. Usando dados de titulares de cartões de crédito de uma financeira ligada a um banco, analisaram-se potenciais influências de variáveis de cadastro e de variáveis macroeconômicas no tempo de sobrevivência, ou seja, de não inadimplência. Os resultados sugerem que modelos que incorporam variáveis macroeconômicas possibilitam melhorar o nível de explicação do tempo de sobrevivência, comparativamente a modelos que utilizam somente dados de cadastro. Considerando variáveis de cadastros, os testes estatísticos apontaram o sexo feminino possui maior sobrevivência, indicando que homens tendem a entrar em inadimplência mais cedo na amostra estudada. Com relação às variáveis macroeconômicas, o nível de desemprego mensal tem maior relevância na explicação de inadimplência.

Full textThis thesis is concerned with credit decision and not with financial statements analysis. More specifically, it is focused on the decision making process of the credit committee once the results of a competent anlysis is avalaible. The thesis is divided in four parts. In the first we present a review about credit, from its historical developments up to the applications of sophisticated portfolio management models and other modern techniques. The second part deals with the fundamentals of decision theory. We discuss ans analyze political and rational decision behaviors within organizations, and phenomenon such as escalation, groupthink and bandwagon. The third part presents, initially, the research problem, its methodology and the hypothesis to be tested. Subsequently, based on eighteen interviews with bank executives in Brazil, we describe the decision processes employed in the concession of credits to large corporations. We also analyze seven cases of unsuccessful credit decisions. Finally we present the statistical analysis of a survey by questionnaires from 54 Brazilian banks. In the fourth and last part we present the conclusions of this thesis. The key results in the importance of behavioral aspects in the credit decision processes: the statistical tests confirm that the rational behavior mitigates the bankruptcy index; while the political behavior, escalation and groupthink contribute to an increment of the banruptcy index.

Dado a importância da gestão de risco associada às operações de crédito, modelos estatísticos que avaliam o risco de inadimplência tornaram-se fundamentais na mensuração do risco associado a um cliente. Neste contexto, foi desenvolvido um modelo dinâmico de crédito utilizando variáveis características dos clientes, comportamentais e macroeconômicas através da Análise de Sobrevivência aplicada a dados discretos. Os resultados obtidos indicam que a inclusão de variáveis macroeconômicas provoca um efeito significativo, porém baixo, no ajuste do modelo. Entretanto, nota-se uma melhora expressiva no poder de previsão da taxa de inadimplência do portfólio quando aplicado a um conjunto de dados de validação.
Statistical models became fundamental in risk measuring associated with a client, mainly when the risk management had grown up his importance associated to credit transactions. In this context, a dynamic credit model was developed using client characteristics, behavioral and macroeconomic variables applying survival analysis to a discrete data. The results indicated the macroeconomics variables inclusion lead to a significant, but low effect in model fit. However, there is a significant improvement in the default rate predictive power of the portfolio when applied to a validation dataset.
