The Role of Collateral in Entrepreneurial Finance

Previous research has suggested collateral has the role of sorting entrepreneurs either by observed risk or by private information. In order to test these roles, this paper develops a model which incorporates a signalling process (sorting by observed risk) into the design of an incentivecompatible menu of loan contracts which works as a self-selection mechanism (sorting by private information). It then tests this Sorting by Signalling and Self-Selection Model, using the 1998 US Survey of Small Business Finances. It reports for the first time that: high type entrepreneurs are more likely to pledge collateral and pay a lower interest rate; and entrepreneurs who transfer good signals enjoy better contracts than those transferring bad signals. These findings suggest that the Sorting by Signalling and Self-Selection Model sheds more light on entrepreneurial debt finance than either the sorting-by-observed-risk or the sorting-by-private information paradigms on their own.

Essays on robust portfolio selection and pension finance

This thesis examines three different, but related problems in the broad area of portfolio management for long-term institutional investors, and focuses mainly on the case of pension funds. The first idea (Chapter 3) is the application of a novel numerical technique – robust optimization – to a real-world pension scheme (the Universities Superannuation Scheme, USS) for first time. The corresponding empirical results are supported by many robustness checks and several benchmarks such as the Bayes-Stein and Black-Litterman models that are also applied for first time in a pension ALM framework, the Sharpe and Tint model and the actual USS asset allocations. The second idea presented in Chapter 4 is the investigation of whether the selection of the portfolio construction strategy matters in the SRI industry, an issue of great importance for long term investors. This study applies a variety of optimal and naïve portfolio diversification techniques to the same SRI-screened universe, and gives some answers to the question of which portfolio strategies tend to create superior SRI portfolios. Finally, the third idea (Chapter 5) compares the performance of a real-world pension scheme (USS) before and after the recent major changes in the pension rules under different dynamic asset allocation strategies and the fixed-mix portfolio approach and quantifies the redistributive effects between various stakeholders. Although this study deals with a specific pension scheme, the methodology can be applied by other major pension schemes in countries such as the UK and USA that have changed their rules.

Sine ira et studio : En kvalitativ analys av institutionaliseringsprocessens konsekvenser inom den nypaganistiska rörelsen Church of All Worlds

Uppsatsen har för avsikt att undersöka hur den nypaganistiska, och i första hand nordamerikanska, rörelsen Church of All Worlds reagerar mot förändring och institutionalisering. För att förstå institutionaliseringsprocessens bakomliggande krafter och identifiera dess konsekvenser, är det övergripande syftet med uppsatsen att utifrån en fallstudie av Church of All Worlds undersöka hur organisationen under sina verksamhetsår förändrats i fråga om (1) förhållande till samhället, (2) ideologi, (3) organisatorisk struktur och (4) ledarskap. Utgångspunkten är att betrakta rörelsen som dels religiös och spirituell, dels organisatorisk och ekonomisk, varför uppsatsen lutar sin teoribildning mot både religions- och samhällsvetenskapen och mot organisationsteorin. Som samhälleliga samt organisatoriska faktorer till Church of All Worlds institutionalisering finner vi den postmoderna motreaktionen mot industrisamhällets missförhållanden samt kritiken mot existensen av den objektiva sanningen. Institutionaliseringens följder är emellertid att rörelsen slutligen upptas som en del av det sen-moderna samhällssystemet. Förändringen märks i första hand då rörelsen under 80-talet förvandlas till en ekonomiskt intresserad organisation med tjänstehierarkier och reglerat ansvar som påföljder. Den byråkratiska arbetsordningen urlakar inte bara rörelsens ideologi, utan tvingar också den nu demokratiskt tillsatte ledaren till radikala åtgärder för att återfå sin makt, något som når sin kulmen i en konflikt med ledarens sorti som yttersta konsekvens.

"Vox Populi, Vox Dei" - A Discussion of Dissent Within the Modern Catholic Church

The final question is: what happens in the meantime? Is it effective to dissent while conservatives hold power and clearty are not about to make any major changes? What good does it do to repeatedly bang one's head against the wall when progress is not being made? There is no one simple answer to this question, but rather several applicable ones. The first possible answer is that dissent currently does little good. The conservative hierarchy is still the dominant force within Catholicism. This hierarchy has made a habit, evidenced by the birth control debate, of pressing its conservative agenda despite popular opposition. Many people think, that if this hierarchy has not given in to the mass of opinion against it yet, dissent is futile and useless. Why argue with someone who does not listen to your argument?

Opening the Windows of the Church to the World: The Creation of Nostra Aetate and Its Impact on the Christian-Jewish relationship

It is important to assert that this study is not a work to inflict guilt on the Catholics or Catholicism for their silence and indifference during the Holocaust. Instead, this study is about the process of moving on from the Catholic Church's past to where the Jewish community's theological existence was finally recognized and the Jewish people were no longer seen as the Others who killed Christ. This was, achieved through a church declaration titled Nostra Aetate (In Our Time). This study records the journey traversed by this declaration, the insurmountable odds it faced in its creation until its promulgation and the impact it has on the Jewish-Christian relationship.

Avaliando questionários de risco e o comportamento do investidor sobre a ótica de behavioral finance

Tolerância ao risco é fundamental quando se tomam decisões financeiras. No entanto, a avaliação da tolerância ao risco tem se baseado ao longo dos anos em diferentes metodologias, tais como julgamentos heurísticos e a teoria da utilidade esperada que tem como base a hipótese dos mercados eficientes. Foi dentro desta ótica que este trabalho se desenvolveu. O objetivo é analisar três diferentes questionários de avaliação ao risco que são na prática amplamente utilizados por consultores financeiros. Foi assumido para isso que os investidores são considerados racionais, conhecem e ordenam de forma lógica suas preferências, buscam maximizar a "utilidade" de suas escolhas, e conseguem atribuir com precisão probabilidades aos eventos futuros, quando submetidos a escolhas que envolvam incertezas. No entanto, em uma análise preliminar dos questionários, estes poderiam estar utilizando conceitos de behavioral finance para avaliarem a tolerância ao risco, ao invés de utilizarem somente a metodologia tradicional da teoria da utilidade esperada. Dessa forma tornou-se necessário o estudo dos conceitos de behavioral finance. O primeiro capítulo então trata dos aspectos psicológicos do investidor, procurando entender como este se comporta e como este forma suas preferências. Apesar do estudo assumir racionalidade nas decisões, se a teoria de behavioral estiver correta e os investidores apresentarem desvios a racionalidade, como a teoria prospectiva afirma, o questionário poderia ser o veículo ideal para identificar tais desvios, sendo possível então educar e orientar o indivíduo em suas escolhas financeiras, afim de maximizá-las. O capitulo dois coloca a análise dos questionários inserida no contexto da teoria moderna de finanças, falando das escolhas de portfólio para investidores de longo prazo. O capítulo mostra de forma bem resumida e simplificada como o investidor maximiza a sua utilidade da riqueza. A idéia desse capítulo é entender como alguns julgamentos heurísticos assumidos na prática por consultores financeiros afetam as escolhas de portfólio e em quais condições esses julgamentos heurísticos são verdadeiros. Isso se torna importante pois os questionários mesclam medidas de risco com horizonte de investimentos do investidor. Estes questionários são utilizados para traçar uma política de investimentos completa para o investidor. Para cada perfil de risco encontrado a instituição traça um modelo de alocação de portfólio. O capítulo três trata da avaliação dos questionários em si tendo como base a teoria da utilidade esperada, os conceitos de behaviral finance e as lições tiradas das escolhas de portfólio para investidores de longo prazo.

Essays on asymmetric information problems without the single-crossing property: applications to corporate finance

The objective of this dissertation is to re-examine classical issues in corporate finance, applying a new analytical tool. The single-crossing property, also called Spence-irrlees condition, is not required in the models developed here. This property has been a standard assumption in adverse selection and signaling models developed so far. The classical papers by Guesnerie and Laffont (1984) and Riley (1979) assume it. In the simplest case, for a consumer with a privately known taste, the single-crossing property states that the marginal utility of a good is monotone with respect to the taste. This assumption has an important consequence to the result of the model: the relationship between the private parameter and the quantity of the good assigned to the agent is monotone. While single crossing is a reasonable property for the utility of an ordinary consumer, this property is frequently absent in the objective function of the agents for more elaborate models. The lack of a characterization for the non-single crossing context has hindered the exploration of models that generate objective functions without this property. The first work that characterizes the optimal contract without the single-crossing property is Araújo and Moreira (2001a) and, for the competitive case, Araújo and Moreira (2001b). The main implication is that a partial separation of types may be observed. Two sets of disconnected types of agents may choose the same contract, in adverse selection problems, or signal with the same levei of signal, in signaling models.

Essays on international finance, default and inflation

This thesis is composed by three papers, each one of them corresponding to one chapter. The first and the second chapters are essays on international finance appraising default and inflation as equilibrium outcomes for crisis time, in particular, for confidence crisis time that leads to speculative attack on the external public debt issued by emerging economies. With this background in mind, welfare effects from adopting common currency (chapter 1) and welfare effects from increasing the degree of economic openness (chapter 2) are analyzed in numerical exercises, based on DSGE framework. Cross-countries results obtained are then presented to be compared with empirical evidence and to help on understanding past policy decisions. Some policy prescriptions are also suggested. In the third chapter we look to the inflation targeting regime applied to emerging economies that are subject to adverse shocks, like the external debt crisis presented in the previous chapters. Based on a more theoretical approach, we appraise how pre commitment framework should be used to coordinate expectations when policymaker announcement has no full credibility and self fulfilling inflation may be possible.
