Esta tesis elabora una caracterización teórica de problemas de agencia dinámicos, basada en métodos recursivos duales. Respecto a las actuales estrategias de solución, la mayor ventaja de mi método es la posibilidad de analizar modelos complicados con muchas variables de estado, como es el caso en muchas situaciones macroeconómicas. El primer Capitulo introduce la metodología y presenta algunos ejemplos numéricos. El segundo Capitulo caracteriza contratos óptimos de participación al riesgo, en los dos casos de economía de dotación y de economía con producción, y demuestra que el método es muy simple en su aplicación a estos problemas. El tercer Capitulo analiza el seguro óptimo de desempleo bajo diferentes supuestos sobre el acceso al mercado financiero y la evolución del capital humano. / This thesis elaborates a theoretical characterization of general dynamic agency problems based on recursive duality methods. With respect to current solution strategies, the main advantage of my approach is the possibility to analyze complicated models with many state variables, as it is the case in several macroeconomic situations. The first Chapter introduces the methodology and provides some numerical example. The second Chapter provides a characterization of optimal risk sharing contracts both in endowment and production economies, and shows how the approach is easy to apply to these problems. The third Chapter analyzes optimal unemployment insurance under different assumptions on access to financial markets and human capital trends.

The first article, 'Simple Contracts under Simultaneous Adverse Selection and Moral Hazard', considers a principal-agent problem under the simultaneous presence of both moral hazard and adverse selection, where the adverse selection dimension is given over the outcome conditional probabilities given the agents actions. The second article, 'Public-Private Partnerships in the Presence of Adverse Selection' analyses the optimality of private-public partnerships under the presence of adverse selection. The third article, 'Regulation Under Stock Market Information Disclosure', by its turn, considers the problem of regulating publicly traded companies, where firms have incentives to send opposing signals to the regulator and the market. / Esta tese é composta de três artigos. No primeiro artigo, 'Simple Contracts under Simultaneous Adverse Selection and Moral Hazard', é considerado um problema de principal-agente sob a presença simultânea dos problemas de risco moral e seleção adversa, em que a dimensão de seleção adversa se dá sobre as distribuições de probabilidade condicionais as ações do agente. No segundo artigo, 'Public-Private Partnerships in the Presence of Adverse Selection' é analisada a otimalidade de parcerias público-privadas sob a presença de seleção adversa. No terceiro artigo, 'Regulation Under Stock Market Information Disclosure', por sua vez, é considerado o problema da regulação de firmas de capital aberto, onde as firmas possuem incentivos para mandar sinais opostos para o regulador e o mercado.

The discussion is based on the empirical approach proposed by Lafontaine (1992). The models are estimated using a database containing information on 350 Brazilian franchisors. The results suggest that moral hazard problems from franchisee side as well as risk sharing are relevant to the definition of royalty rate value. Particularly, in business where the franchisee effort has significant influence on the input quality of the services provided, the royalty rate tends to decrease. Our results fails to identify a negative tradeoff between risk and incentives. CConcerning the expansion strategy option, as expected by the theory, results indicate that firms tend to expand through franchising when agent effort is relevant. However, opposed to the capital constraint hypothesis, our findings suggests that decisions to adopt franchising as a growth strtategy are not related to capital restrictions. / O presente estudo tem um duplo objetivo: (i) analisar os determinantes da escolha das firmas por um modelo de franchising na estratégia de expansão de seus negócios, e (ii) analisar como os termos de um contrato de franchising podem potencialmente ser influenciados por questões relativas a compartilhamento de risco, problemas de incentivo relacionados ao risco moral (moral hazard) e restrições de recursos financeiros. Essa discussão se dará seguindo a abordagem empírica proposta por Lafontaine (1992). Os modelos são estimados a partir de dados para uma amostra de 350 redes de franquias brasileiras relativas ao ano de 2011. Os resultados sugerem que a definição do valor da taxa de royalties leva em conta os problemas decorrentes do risco moral por parte dos franqueados e do compartilhamento de risco. Em particular, nos negócios onde o esforço dos franqueados afeta significativamente a provisão dos serviços prestados, observa-se uma tendência de cobrança de menores taxas de royalties e uma relação positiva entre risco e incentivos, com a cobrança de menores taxas de royalties em setores de atividade com maior risco. Em relação ao percentual de unidades franqueadas, obteve-se resultados coerentes com a expectativa teórica para o problema de risco moral do franqueado, de modo que quanto mais importante o trabalho do agente, maior o índice. Entretanto, para a restrição de capital, contrário a expectativa teórica, quanto maior a disponibilidade de recursos maior o número de franquias.

Were evaluated the most relevant failure point in the relationship of the financial system in the moments that preceded the 2008s crisis, looking for information distortions that could take to a financial crisis. After that, it was presented a theoretical model which defines the equilibrium conditions of the financial system and then presented some applications of the deviations observed in reality to create an operation system that modifies this equilibrium taking it to grow the number of projects that are financed based on an increase of the moral hazard and also the risk of failure of these projects. In the end it was presented methodologies to mitigate the risks of crisis like the one experienced in the last few years. / O presente trabalho tem por objetivo adaptar um modelo de intermediação financeira, incluindo nele elementos chave que levam a uma crise no setor financeiro tal qual observado no mundo real. Foram avaliados os principais pontos de falha nas relações do sistema financeiro no período que precedeu a crise de 2008, buscando distorções de informações que possam levar a crises financeiras. Na sequência, foi apresentado um modelo teórico que define as condições de equilíbrio do sistema financeiro, a partir dele foram aplicadas as distorções levantadas da realidade de modo a criar um sistema de operação que modifica as condições de equilíbrio, aumentando a quantidade de projetos sendo financiados com base em um aumento do risco de falha desses projetos. Por fim foram apresentadas metodologias que mitigam os riscos de ocorrência de crises como as recém observadas.

At the same time, the degree of sophistication of its legal environment and contractual structures has increased to cope with the particularly intense agency problems present due to (i) low liquidity of assets; (ii) the long term nature of contracts; (iii) the potentially huge asymmetry of information between investors and managers. This dissertation explores the presence of restrictions to the venture capital fund managers’ activities; and shows that there is a strong relation between the number of restrictions and the intensity of agency problems, but inconclusive evidence relating the restrictions to demand conditions. / Nas duas últimas décadas, o papel dos setores de private equity e venture capital no Brasil aumentou significativamente, com a expansão do volume de recursos sob gestão e do número de transações. Ao mesmo tempo, a sofisticação do marco legal e das formas de contratação aumentou para que fosse possível lidar com os problemas de agência, que são particularmente intensos devido (i) à baixa liquidez dos ativos em que investe, (ii) à duração do compromisso entre as partes e (iii) à potencialmente elevada assimetria de informação entre elas. Este trabalho explora a presença de restrições às atividades dos gestores de recursos de private equity e venture capital, e mostra que há uma forte correlação entre a quantidade de restrições e a intensidade dos problemas de agência, mas que as evidências quanto à relação entre as restrições e as condições de demanda não são conclusivas.

We used a series of multiple linear regressions with OLS estimation to investigate whether compensation is positively associated with shareholder return. Our sample includes 525 observations and comprises a three-year period (2014, 2015 and 2016). We find that, in general, pay is positively associated with performance but that this sensitivity is not sufficiently large. We also confirm that stock-based compensation and a higher governance level are important for aligning pay and performance. Firms with concentrated ownership tend to pay less, which suggests that monitoring decreases the need of pay to align incentives or reduces the power of executives to set their own compensation. Finally, our model suggests that fixed compensation is adjusted to meet the reservation utility and information rent whereas variable compensation serves to address moral hazard. / Este estudo enfoca a relação entre remuneração dos executivos, desempenho da empresa e retorno para o acionista de executivos de empresas brasileiras de capital aberto. Utilizamos uma série de regressões lineares múltiplas com estimativa de mínimos quadrados comuns (OLS) para investigar se a remuneração dos executivos está positivamente associada ao retorno do acionista. Nossos dados foram coletados do Formulário Referência da BM&FBOVESPA (equivalente ao SEC 20-F), Economatica e Bloomberg, e nossa amostra incluiu 525 observações e compreende um período de três anos (2014, 2015 e 2016) com dados de 175 empresas. Concluímos que, em geral, o pagamento está positivamente associado ao desempenho, mas que essa sensibilidade não é suficiente. Também confirmamos que a remuneração que inclui opções, bem como empresas com um nível de governança superior são fatores importantes para alinhar o salário e o desempenho. As empresas com controle concentrado tendem a pagar menos, o que sugere que o monitoramento diminui a necessidade de incentivos financeiros para alinhar interesses ou diminui o poder dos executivos para estabelecer sua própria remuneração.

A presente dissertação analisa como a ausência de incentivos adequados no seguro saúde ocasiona o surgimento do fenômeno conhecido como risco moral e suas conseqüências na determinação da demanda de serviços médicos. O trabalho envolve a revisão da literatura e a estimação de um modelo econométrico que avalia a efetividade dos mecanismos de regulação no controle do risco moral por parte do paciente. A principal conclusão é que o risco moral por parte do paciente é importante para os serviços ambulatoriais, mas não ocorre nos serviços hospitalares. / This dissertation analyses how the lack of appropriate incentives motivates the emergence of moral hazard in health insurance and its consequences in the determination of medical services demand. The involves the literature review and the estimation of a econometric model, which evaluates the effectiveness of rationing mechanisms in the control of moral hazard motivated by the patient. The main conclusion is that moral hazard motivated by the patient is significant for ambulatory care, but it does not occur for inpatient care.

I find that the TARP capital injection significantly enlarged the interbank exposure for the TARP recipients relative to others, particularly for banks in smaller size, with lower level of interbank trading and located in relatively poor economic conditions. I further test whether the distorted interbank liquidity position of the TARP recipients stimulated their credit risk appetite. I find that TARP recipient banks with larger interbank exposure also significantly shifted to riskier credit portfolios than others after the TARP implementation, suggested by estimates on forward- and backward-looking risk measures. Results are robust to the instrumental variable analysis, the sample self-selection model, the propensity score matching analysis, various placebo experiments and alternative econometric models. My results are most consistent with the “capital spillover” hypothesis that banks used the TARP capital to develop more interconnected interbank relationships, and the moral hazard effect that higher future bailout expectation and increased systemic relevance jointly construct a “new government safety net” for the TARP beneficiaries to take excessive credit risks under the implicitly perceived “too interconnected to fail” protection.
