This thesis studies bank behaviour in response to financial regulation and monetary policy. In the first chapter a novel approach to address issues of endogeneity in estimating a causal effect of leverage on risk taking by banks is used. By using data on local bank office deposits and local unemployment an instrument is constructed to use in a regression of leverage on a measure of risk taking constructed from new issuance of loans. The results are consistent with a theoretical prediction that due to limited liability banks increase their risk taking after an exogenous increase in leverage. The second chapter estimates the effect of deposit insurance on the risk-taking behaviour of banks. As shown in the theoretical literature, deposit insurance may induce moral hazard and incentivise banks to take on more risk. This chapter provides an experimental setup in which an increase in the coverage limit of deposit insurance in the U.S. is exploited in order to identify the difference in risk taking by banks that were affected and banks that were not. This difference comes from the fact that state chartered savings banks in Massachusetts had unlimited deposit insurance coverage at the time when it was increased for all other banks in the US. Given that all banks in the sample are subject to the same regulatory and supervisory requirements, and that they are similar in other characteristics, the effect of such increase in deposit insurance can be isolated. The findings suggest that, contrary to the literature, an increase in deposit insurance did not increase bank risk-taking, nor did it affect market discipline, evident through a lack of effect on deposit rates. Motivated by substantial differences in employment dynamics across different geographical areas and substantial differences across banks which operate in these geographical areas, the third chapter estimates the effect of characteristics of banks operating in a particular location on the impact of monetary policy on the local economic outcomes. The results suggest that the effect of monetary policy on local employment and local total payroll intensifies as the capital structure of local banks improves and the credit risk associated with local banks decreases. These findings go in line with a prediction that healthy banks find it easier to attain alternative sources of funding following a monetary tightening. The results also show that size and liquidity position of local banks does not affect the impact of monetary policy.

Texte intégralThe search for greater availability of long-term credit for productive investments in Brazil has been gaining importance since it enables companies to engage in medium and large-scale businesses, feeding the economic growth and development processes. The line of credit provided by BNDES, called Financing to Enterprises (Finem), is one of the few lines existing in Brazil which offers the possibility of financing investment projects with large amounts and long-term maturity. However, the amount provided by this line has shown little progress in relation to GDP. It was expected an increase of that availability with the Real Plan and the creation of an economic environment favorable to long-term planning, which did not occur. Thus, this study aims to evaluate the main factors influencing the availability of long-term credit in Brazil for productive investments, not only in order to expand it but also creating conditions for multiple banks to effectively participate in that process. The model specified for this study included variables such as the disbursements of the Finem line of credit, representing the availability of that credit, and others related to macroeconomic issues, theoretical framework of market failures and government intervention and BNDES performance, with data collected between 2001 and 2011. Using an Autoregressive Model with Vector Error Correction (VEC), this study notes the importance of government intervention, through allocation of resources, in providing this type of credit, confirming the hypothesis that although BNDES presents good levels of performance and seeks to diversify its funding sources, government intervention is still an essential alternative to increase the availability of that line of credit. This study also shows that economic stability is a relevant factor, for allowing long-term planning, by empirically confirming previous studies on the subject. Other factors such as economic growth, availability of alternatives and BNDES lending performance are directly related to the availability of such credit. On the other hand, BNDES profits have little importance on Finem disbursements, a result that is justified by the BNDES Basel Ratio ascertained in that period. The result concerning the influence of Brazil Risk index, in turn, shows that the external funds obtained by BNDES may have been guided by other factors such as budgetary issues or government policies. The results indicate that policy makers would consider government intervention in the allocation of resources to multiple banks, so that they can intensify the availability of such credit. Finally, this study exposes the necessity to dedicate more attention to the destination of resources from this particular type of credit, so that it can effectively contribute to promote growth and development in Brazil.

Notre analyse se concentre sur les stratégies institutionnelles des fédérations syndicales sectorielles européennes et sur leurs implications en matière d’européanisation de la politique salariale. Nous avons démontré que le développement des processus de coordination européenne des négociations collectives nationales, en particulier au niveau sectoriel, peut contribuer à renouveler la conception de la négociation collective et des relations professionnelles dans l’espace européen jusqu’alors appréhendée dans la littérature par le dialogue social. Nous avons identifié trois obstacles à la négociation collective européenne :le salaire « dépolitisé » dans le partenariat économique, le patronat devenu « partenaire-lobby » dans le dialogue social sectoriel, et la difficile européanisation syndicale.

In this thesis, I show that governments bail out banks because banks are critical to capitalist democracies. Banks enjoy a public safety net. Governments, however, can make banks pay for this protection. Two of this dissertation’s conclusions stand out. The first is that the influence of business through lobbying and other channels of instrumental power is exaggerated. Banks cannot secure sweetheart deals by pointing to their track record of campaign contributions. Bailouts are not for sale. During crises, governments can use banks’ dependence on the domestic market to force them to bear the bailout costs. Only highly international banks, can parry this threat by using their structural power strategically. The second conclusion is that financial crises remove veto points. They create a large threat and leave little time for deliberation, which prompts lawmakers defer to the executive branch. Thus, financial crises shift power from legislatures—even strong ones, like the US Congress—to the head of government.

This thesis is a nexus of three topics; financial stability, banking regulation and financial influence. In four separate chapters, this work examines how financial institutions interact with their regulators, in particular after the financial crisis of 2008. Size, incentives, guarantees, moral hazard, treatment, capture and influence play an important role in the analysis. The first chapter focusses on the relation between bank size and support, confirming the hypothesis that bank size is positively related to support ratings. It also finds evidence that the effect is non-linear, confirming the ‘too-big-to-rescue’ theory. Chapter two tests whether the expectation of individual and systemic government support induces moral hazard. It shows that banks tend to be more leveraged, funded with capital of lower quality, more heavily invested in risky assets and exposed to more severe liquidity mismatch when they are perceived as being more likely to benefit from government support. In the last two chapters the focus is shifted to banks’ political activities and connections. Both chapters leverage a unique dataset that links U.S. banks’ sources of influence (e.g., lobbying expenditures, proximity to the relevant legislative committee, prior affiliation with regulatory or government institutions) to bank financial data, actual bank supervisory actions, and market-inferred expected government support. The findings in chapter three suggest that banks’ political influence indeed matters for the regulatory treatment of distressed banks, as well as for the expectation of support regardless of bank distress. Chapter four further dives into determinants of bank lobbying, and explores whether political connections and risk taking influence the decision to lobby. In combination, these findings are instructive for understanding the political landscape surrounding banks and their regulators. It also helps us to have a broader understanding of what drives government support to banks, and how in turn that support can trigger moral hazard within banks.

Texte intégralWe assemble a new data set on bank failures, bailout with public finances, in the European Union (E.U.), in the wake of the on-going financial crisis. Our model is estimated with data on 444 commercial banks from 19 countries in Europe over 2004-2010, which yields a sample of 1,504 unbalanced panel observations. Results show that bank failures were critically determined by financial accounting information and macroeconomic conditions, and that macroeconomic information improves the forecasting ability of our model over and above financial accounting information. The predictors from our model can be used by monetary authorities to predict bank failures, and the probabilities to assess pressure in the banking sector, the pricing of credit, and their derivatives. Our findings are consistent with recent regulatory impositions in the Basel setting that require banks to hold higher capital levels and lower risks.
Reunimos um conjunto de dados recentes sobre bancos com eventos de incumprimento e de resgate financeiro estatal, na União Europeia (U.E.), no contexto da actual crise financeira. O modelo foi estimado com dados de 444 bancos comerciais de 19 países da U.E. para o período de 2005-2010, o que produziu uma amostra de 1.504 observações, em painel não balanceado. Os resultados mostram que os eventos de incumprimento e resgate nos bancos considerados foram significativamente influenciados pelos seus dados contabilísticos e pelas condições macroeconómicas do país de origem, sendo que os dados macroeconómicos aumentam a capacidade de previsão do modelo muito além dos dados contabilísticos. As variáveis explicativas do nosso modelo podem ser usadas pelas autoridades monetárias a nível mundial para prever eventos de incumprimento de bancos e avaliar eventuais pressões no sector financeiro resultantes das políticas de crédito. Os nossos resultados são consistentes com as recentes imposições regulamentares de Basileia, que exigem que os bancos mantenham níveis mais altos de capital e níveis de risco mais baixos.

Texte intégralThis paper studies the efficacy of bank bailouts in restoring financial stability during financial crises. Stability is measured in terms of stock market volatility. The volatility dynamics associated with banking crises in South Korea, Malaysia, Indonesia, Thailand, and the United States (US) are investigated. Using daily returns data from 1 January 1997 to 8 October 2012, two specific methods are used to measure the impact of bailouts on financial stability. Firstly, dummy variables that account for the timing of bailout policies are included in the variance equation of Exponential Generalised Autoregressive Conditional Hetereoskedasticity (EGARCH) models that are estimated for the overall stock market index of each of the affected countries. Secondly, EGARCH models are estimated using 30-day rolling windows in order to control for shifts in unconditional volatility that may result from bailouts. The Spearman Rank-Order correlation test is used to assess the rank-order relationship between the EGARCH 30-day rolling window conditional volatility and actual volatility, which is estimated as a 30-day moving average of squared returns. Three main findings form the conclusion of this study. The first is that, in some cases, bailouts are successful in reducing volatility in some of the East Asian and US stock markets. Secondly, although the creation of centralised asset management companies and the implementation of guarantees of liabilities as bailout policies are effective at reducing volatility in the East Asian markets, closures of, and interventions in, banks and other financial institutions, liquidity support, and capital support are not effective in reducing volatility in the East Asian markets. This illustrates that different bailout policies have different impacts on volatility. Finally, although bailout policies reduce volatility, liquidity support, and capital support, bailout policies are more effective at reducing volatility in the United States than in the East Asian countries. This illustrates that the same bailout policies cannot be used in different types of economies, namely developed and developing economies, with the hope of the same outcome being realized.

Texte intégralI investigate the effects of the European Central Bank monetary policy over the European government bonds market. To obtain the instantaneous reactions of government bonds, I use event studies to evaluate the impact of changes on monetary policy – the events – over the cumulative average abnormal return of bond yields. I conclude that the European Central Bank monetary policy did have significant effects on Euro-zone government bonds and other European countries. Among eight countries, the German 5-year government bonds were the most responsive to the events. On the other hand, the United Kingdom, which does not belong to the Euro-zone, was the least responsive. I also find that the event with the strongest impact on the bond markets is the announcement of 4th September 2014. Most of bond yields show significant reactions on the day after the announcement date, but the 5-year government bonds is affected much more than the 10-year government bonds.
Investigamos o efeito da decisão da política monetária do Banco Central Europeu em relação aos principais ajustes das taxas de juros no mercado de obrigações governamentais em vários países da União Europeia. Para obter as respostas instantâneas dos títulos do governo, é utilizado o Estudo de Eventos para avaliar o impacto das decisões através do retorno anormal médio acumulado das taxas de rendibilidade das obrigações. O estudo consegui que a política monetária do BCE teve um efeito significativo nos títulos do governo da zona do euro e não só. A maturidade de cinco anos da Alemanha revelou ser o mais sensível aos eventos entre oito países analisados. Por seu turno, o Reino Unido, país fora da zona Euro, foi aquele cujas obrigações menos reagiram. O estudo confirma um impacto mais relevante sobre as obrigações governamentais relativamente ao anúncio da decisão de 4 de setembro de 2014. A maior parte dos rendimentos das obrigações apresentou reações significativas no dia seguinte à data do anúncio, mas as obrigações a cinco anos revelaram ser mais afetadas do que as a 10 anos.

Abstract In the recent years, real estate market pricing including housing price in part of areas in Taiwan has been increased. The reasons for such increase include too many hot monies without proper investment vehicles, low-interest investment environment, and problems of tax policies with respect to real estate. And people have started to doubt policies related to the right of adequate and affordable housing implemented by the Government. Recently, main focus of real estate market lies on that price thereof has been overly high and problems of tax policies which have leaded to real estate tax policies reform. In order to improve real estate tax policies, the Government needs to take care of real estate market, the right of adequate and affordable housing and fairness of tax rate. Credit business is the main business of financial institutions and the expected effects of policy already caused the trading volume of real estate market shrinking. In the event that the prosperity of the economic environment and the real estate market turn down, overdue loans and bad debts will increase. Financial institutions should act sooner and implement related measures in order to response to the real estate tax policies to be reformed by the Government, and to lower its own risks regarding real estate credit business. When making real estate loans including housing loans, financial institutions should consider whether the location of the subject real estate is good, the financial status and reputation of the construction company and its past projects and should investigate the company’s financial source and its ability to raise funds. In order to control the risk of residential real estate loans, loan commitment for owner-occupied residence could lower the risk weight of capital charge, and improve the Bank of International Settlement ratio:BIS ratio Therefore, more loan commitment for owner-occupied residence is advised for the banking industry.

Texte intégralEsta dissertação é constituída por três artigos sobre gestão de risco de crédito e engloba diferentes tipos de empresas que podem ser observadas na carteira de crédito de um banco. Foi usada uma extensa base de dados do Banco de Portugal, com cerca de 43.000 demonstrações financeiras de mais de 16.000 empresas, no periodo compreendido entre 1997 e 2003. Cerca de 2.500 observações pertencem a empresas que entraram em incumprimento de crédito, conforme a definição de Basileia II, representando 6% do total de observações da base de dados em estudo. No desenvolvimento das estimações empíricas, foram aplicadas diferentes metodologias e sub-grupos de observações da base de dados principal, no sentido de garantir a qualidade dos dados usados, bem como a robustez dos resultados obtidos. O primeiro artigo, no capítulo 1, estuda a influência da avaliação do auditor externo sobre a capacidade de continuidade de uma empresa através da análise dos eventos de incumprimento de crédito após a produção do relatório do auditor. Os requisitos profissionais da função de auditoria implicam que o auditor externo, na elaboração da sua opinião, tenha em consideração e informe explicitamente sempre que existam dúvidas significativas sobre a capacidade de continuidade de uma empresa. A primeira intenção do estudo foi determinar se a avaliação sobre a capacidade de continuidade de uma empresa, por parte do auditor externo, conteria informação substancial, examinando para isso as empresas que entraram em incumprimento de crédito após a emissão de dúvidas por parte do auditor. Nesse sentido, foram usados 12.199 relatórios de auditoria relativos a cerca de 2.000 empresas obrigadas por lei a ter as respectivas contas auditadas anualmente. A estimação empirica de um modelo logit, controlando informação contabilística de cash flows bem como variáveis não contabilísticas, mostra que nas empresas que receberam, na opinião do auditor externo, dúvidas sobre a capacidade de continuidade, a probabilidade de incumprimento de crédito é 2,792 vezes superior em comparação com as empresas sem esse tipo de opinião. Os testes de Likelihood ratio para a omissão de variáveis confirmam o valor incremental preditivo da opinião do auditor externo sobre a capacidade de continuidade das empresas, quando comparado com variáveis contabilísticas e não contabilísticas, na estimação de base e nas estimações através de bases de dados de comparação (out-ofsample). No grupo de empresas que não entraram em incumprimento de crédito, a taxa média de incumprimento estimada é de 6.05%, enquanto no grupo de empresas que entraram em incumprimento a taxa média de incumprimento estimada é de 17.78%. A taxa de incumprimento estimada de crédito para o grupo de empresas que não entraram em incumprimento e que receberam uma opinião de incerteza sobre a capacidade de continuidade, por parte do auditor externo, é de 9.92%, enquanto para as restantes empresas a taxa média é de 5.96%. No grupo de empresas que entraram em incumprimento de crédito, e nesse grupo, as empresas que receberam uma opinião de incerteza por parte do auditor externo, a taxa média estimada é de 35.49%, enquanto para as restantes empresas do mesmo grupo, a taxa média estimada é de 16.96%. A confirmação da robustez das conclusões através da análise de diferentes dimensões de empresas, antiguidade das empresas, sectores e regiões geográficas indicam que as empresas que receberam uma opinião de incerteza de capacidade de continuidade por parte do auditor externo, em média, entram mais em incumprimento de crédito do que as empresas que não têm qualquer opinião de incerteza por parte do auditor externo. O segundo artigo, no capítulo 2, usa a totalidade dos dados e analisa os eventos de incumprimento de crédito para sociedades anónimas não cotadas e para sociedades por quotas, no sentido de perceber as características de incumprimento de crédito para cada um dos grupos de empresas. São estudadas seis hipóteses teóricas que relacionam a influência de rácios contabilísticos e as respectivas propriedades distributivas relacionadas com o incumprimento de crédito. Adicionalmente, duas hipóteses são testadas relacionando a influência do enquadramento e responsabilidade legal e o incumprimento de crédito, bem como o incremento da capacidade preditiva do enquadramento legal relativamente aos rácios contabilísticos na estimação de incumprimento de crédito. Os seguintes rácios: cash flow sobre a divida total; cash flows operacionais sobre os custos financeiros da dívida; capitais próprios sobre o total de activos; e liquidez; têm uma relação negativa com o incumprimento de crédito. A dimensão da empresas e a respectiva idade também estão relacionados negativamente com o incumprimento de crédito. As sociedades anónimas estão relacionadas positivamente com o incumprimento de crédito comparativamente às sociedades por quotas. A probabilidade de incumprimento estimada para sociedades por quotas é 0,83 vezes a probabilidade de incumprimento das sociedades anónimas. Os testes de Likelihood ratio para a omissão de variáveis também confirmam o valor incremental preditivo do enquadramento legal, quando comparado com informação contabilística, na estimação de base e estimações através de bases de dados de comparação (out-of-sample). No grupo de empresas que não entraram em incumprimento de crédito, para sociedades anónimas, a taxa média de incumprimento estimada é 0.53% superior à taxa de incumprimento estimada para sociedades por quotas. A mesma diferença é 2,07% superior no grupo de empresas que entraram em incumprimento de crédito. A confirmação da robustez das conclusões através da análise de diferentes dimensões de empresas indicam que a vantagem das sociedades por quotas diminui com a dimensão das empresas. O terceiro artigo, no capítulo 3, apresenta um modelo baseado em rácios contabilísticos e não contabilísticos para determinar o incumprimento de crédito de empresas não cotadas e um método de estimação de probabilidades de incumprimento de crédito o qual pode ser usado pelo banco central em Portugal para calcular os requisitos minimos de capital regulamentar dos bancos, bem como a sua utilização como benchmarks na validação de modelos de rating internos da banca comercial. O Comité de Supervisão Bancária de Basileia refere a necessidade de os bancos centrais e a banca comercial modelizarem e estimarem probabilidades de incumprimento de crédito tendo em consideração as respectivas especificidades dos portfólios e países em questão. Relativamente a empresas não cotadas existem poucos estudos relacionados com incumprimentos de crédito. Nesse sentido, é usada uma base de dados do Banco de Portugal com 31.025 demonstrações financeiras de empresas não cotadas. Os dados usados incluem 30 rácios contabilísticos e informação não contabilística sobre a dimensão e idade das empresas, sector, e região geográfica. Em relação aos rácios contabilísticos: os custos financeiros sobre os resultados brutos; solvabilidade; e a formação bruta de capital fixo sobre o total de activos têm a influência mais significativa na probabilidade de incumprimento de crédito. Os rácios contabilísticos que apresentam menor influência marginal na probabilidade de incumprimento de crédito são a: rendibilidade dos activos; cobertura financeira; prazo médio de pagamentos; prazo médio de recebimentos; e rendibilidade dos capitais próprios. Adicionalmente, e ao contrário das observações no contexto de empresas cotadas, a dimensão da empresa aparece positivamente relacionada com o incumprimento de crédito, e apesar da idade da empresa surgir negativamente relacionada, a sua contribuição marginal na influência da estimação de probabilidades de incumprimento é reduzida. A análise da influência conjunta de variáveis contabilísticas e não contabilísticas mostra que a dimensão das empresas altera a relação de algumas variáveis com o evento de incumprimento de crédito. Os resultados também indicam variações sectoriais e geográficas nos dados de incumprimento de crédito. Os resultados sugerem que a informação relacionada com empresas cotadas não pode ser generalizada nem aplicada igualmente pelos reguladores às empresas não cotadas. Em suma, os resultados dos três artigos apresentam informação importante não apenas para a gestão de risco de crédito de instituições financeiras, mas também para os reguladores e autoridades de supervisão financeira.
