Optimal performance fee and flow of funds in asset management contracts

This paper investigates the importance of ow of funds as an implicit incentive in the asset management industry. We build a two-period bi- nomial moral hazard model to explain the trade-o¤s between ow, per- formance and fees where e¤ort depends on the combination of implicit ( ow of funds) and explicit (performance fee) incentives. Two cases are considered. With full commitment, the investor s relevant trade-o¤ is to give up expected return in the second period vis-à-vis to induce e¤ort in the rst period. The more concerned the investor is with today s pay- o¤, the more willing he will be to give up expected return in the second period by penalizing negative excess return in the rst period. Without full commitment, the investor learns some symmetric and imperfect infor- mation about the ability of the manager to obtain positive excess return. In this case, observed returns reveal ability as well as e¤ort choices. We show that powerful implicit incentives may explain the ow-performance relationship with a numerical solution. Besides, risk aversion explains the complementarity between performance fee and ow of funds.

Tests of conditional asset pricing models in the brazilian stock market

In this paper, we test a version of the conditional CAPM with respect to a local market portfolio, proxied by the Brazilian stock index during the period 1976-1992. We also test a conditional APT modeI by using the difference between the 3-day rate (Cdb) and the overnight rate as a second factor in addition to the market portfolio in order to capture the large inflation risk present during this period. The conditional CAPM and APT models are estimated by the Generalized Method of Moments (GMM) and tested on a set of size portfolios created from individual securities exchanged on the Brazilian markets. The inclusion of this second factor proves to be important for the appropriate pricing of the portfolios.

A stochastic discount factor approach to asset pricing using panel data

Using the Pricing Equation, in a panel-data framework, we construct a novel consistent estimator of the stochastic discount factor (SDF) mimicking portfolio which relies on the fact that its logarithm is the ìcommon featureîin every asset return of the economy. Our estimator is a simple function of asset returns and does not depend on any parametric function representing preferences, making it suitable for testing di§erent preference speciÖcations or investigating intertemporal substitution puzzles.

Exact arbitrage, well-diversified portfolios and asset pricing in large markets

: In a model of a nancial market with an atomless continuum of assets, we give a precise and rigorous meaning to the intuitive idea of a \well-diversi ed" portfolio and to a notion of \exact arbitrage". We show this notion to be necessary and su cient for an APT pricing formula to hold, to be strictly weaker than the more conventional notion of \asymptotic arbitrage", and to have novel implications for the continuity of the cost functional as well as for various versions of APT asset pricing. We further justify the idealized measure-theoretic setting in terms of a pricing formula based on \essential" risk, one of the three components of a tri-variate decomposition of an asset's rate of return, and based on a speci c index portfolio constructed from endogenously extracted factors and factor loadings. Our choice of factors is also shown to satisfy an optimality property that the rst m factors always provide the best approximation. We illustrate how the concepts and results translate to markets with a large but nite number of assets, and relate to previous work.

A stochastic discount factor approach to asset pricing using panel data asymptotics

Using the Pricing Equation in a panel-data framework, we construct a novel consistent estimator of the stochastic discount factor (SDF) which relies on the fact that its logarithm is the "common feature" in every asset return of the economy. Our estimator is a simple function of asset returns and does not depend on any parametric function representing preferences. The techniques discussed in this paper were applied to two relevant issues in macroeconomics and finance: the first asks what type of parametric preference-representation could be validated by asset-return data, and the second asks whether or not our SDF estimator can price returns in an out-of-sample forecasting exercise. In formal testing, we cannot reject standard preference specifications used in the macro/finance literature. Estimates of the relative risk-aversion coefficient are between 1 and 2, and statistically equal to unity. We also show that our SDF proxy can price reasonably well the returns of stocks with a higher capitalization level, whereas it shows some difficulty in pricing stocks with a lower level of capitalization.

O modelo de avaliação de ativos: (Capital asset pricing model)

Examina o modelo de seleção de portfólios desenvolvido por Markowitz, principalmente no que concerne: as suas relações com a teoria da utilidade de Von Neumann-Morgenstern; aos algo ritmos de solução do problema de Programação Quadrática paramétrica dele decorrente; a simplificação proporcionada pelo Modelo Diagonal de Sharpe. Mostra que a existência de um título sem risco permite a especificação do Teorema da Separação e a simplificação do problema de seleção de portfólios. Analisa o modelo denominado por CAPM, de equilíbrio no Mercado de Capitais sob condições de incerteza, comparando os processos dedutivos empregados por Lintner e Mossin. Examina as implicações decorrentes do relaxamento dos pressupostos subjacentes ã esse modelo de equilíbrio geral, principalmente a teoria do portfólio Zero-Beta desenvolvida por Black.

Asset pricing when risk sharing is limited by default: a theoretical framework

We study the asset pricing implications of an endowment economy when agents can default on contracts that would leave them otherwise worse off. We specialize and extend the environment studied by Kocherlakota (1995) and Kehoe and Levine (1993) to make it comparable to standard studies of asset pricillg. We completely charactize efficient allocations for several special cases. We illtroduce a competitive equilibrium with complete markets alld with elldogellous solvency constraints. These solvellcy constraints are such as to prevent default -at the cost of reduced risk sharing. We show a version of the classical welfare theorems for this equilibrium definition. We characterize the pricing kernel, alld compare it with the one for economies without participation constraints : interest rates are lower and risk premia can be bigger depending on the covariance of the idiosyncratic and aggregate shocks. Quantitative examples show that for reasonable parameter values the relevant marginal rates of substitution fali within the Hansen-Jagannathan bounds.

Asset float and speculative bubbles

We model the relationship between ftoat (the tradeable shares of an asset) and stock price bubbles. Investors trade a stock that initiaUy has a limited ftoat because of insider lock-up restrictions but the tradeable shares of which increase over time as these restrictions expire. A speculative bubble arises because investors, with heterogeneous beliefs due to overconfidence and facing short-sales constraints, anticipate the option to reseU the stock to buyers with even higher valuations. With limited risk absorption capacity, this resale option depends on ftoat as investors anticipate the change in asset supply over time and speculate over the degree of insider selling. Our model yields implications consistent with the behavior of internet stock prices during the late nineties, such as the bubble, share turnover and volatility decreasing with ftoat and stock prices tending to drop on the lock-up expiration date though it is known to aU in advance.

Temporary exchange rate-based stabilization programs under asset market segmentation

This paper analyses the welfare consequences of temporary exchange rate-based stabilization programs. Differently than previous papers, however, here we assume that only a fraction of households participates in asset market transactions. With this asset market segmentation assumption, the effects of temporary programs on welfare may change drastically. Households with access to the bonds market are able to protect themselves better from the changes in the inflation rate – although at the cost of a distortion in their consumption path. As a consequence, they may decrease their inflation tax burden – which would increase for the other group of households. By the other side, when these agents that lack the access to the asset markets are credit constrained, they may welcome the program, since the government Is temporally reducing the inflation tax they have to pay. The temporary program could end up benefiting both groups, what could help to understand their popularity.

Optimal provision of implicit and explicit incentives in asset management contracts

This paper investigates the importance of the fiow of funds as an implicit incetive provided by investors to portfolio managers in a two-period relationship. We show that the fiow of funds is a powerful incentive in an asset management contract. We build a binomial moral hazard model to explain the main trade-ofIs in the relationship between fiow, fees and performance. The main assumption is that efIort depend" on the combination of implicit and explicit incentives while the probability distrioutioll function of returns depends on efIort. In the case of full commitment, the investor's relevant trade-ofI is to give up expected return in the second period vis-à-vis to induce efIort in the first período The more concerned the investor is with today's payoff. the more willing he will be to give up expected return in the following periods. That is. in the second period, the investor penalizes observed low returns by withdrawing resources from non-performing portfolio managers. Besides, he pays performance fee when the observed excess return is positive. When commitment is not a plausible hypothesis, we consider that the investor also learns some symmetríc and imperfect information about the ability of the manager to generate positive excess returno In this case, observed returns reveal ability as well as efIort choices exerted by the portfolio manager. We show that implicit incentives can explain the fiow-performance relationship and, conversely, endogenous expected return determines incentives provision and define their optimal leveIs. We provide a numerical solution in Matlab that characterize these results.

Docagem ou afretamento de UMS: a escolha ótima para a extensão da vida útil das plataformas de petróleo de campos marítimos maduros sob o enfoque das opções reais

O objetivo deste trabalho é propor a utilização do arcabouço teórico das opções reais e a posterior aplicação do modelo binomial na avaliação de projetos relacionados à exploração e produção de petróleo, tendo em vista a flexibilidade gerencial, os riscos e as incertezas técnicas e de mercado que norteiam o setor petrolífero upstream. Ademais, a aplicação do modelo proposto capta o papel crucial da volatilidade do preço do petróleo na avaliação da decisão de investimento e revela a existência dos custos irrecuperáveis extremos decorrentes do ativo real, neste caso, a unidade marítima de petróleo. Assim, com o intuito de prolongar o ciclo de produção de unidade marítima de petróleo com características preestabelecidas, propõe-se a avaliação econômica de duas alternativas tecnológicas para a extensão de vida útil da plataforma marítima objeto de estudo, sendo estas alternativas tratadas como opções de expansão. As alternativas propostas são duas: o afretamento da UMS (Unidade de Manutenção e Segurança) acoplada à plataforma e a docagem da plataforma a partir da desmobilização, isto é, o descomissionamento, e envio da plataforma ao estaleiro. Na aplicação da primeira opção, a UMS se configura em uma embarcação equipada com toda a estrutura necessária para a realização de serviço de manutenção e revitalização, sem que ocorra interrupção da produção de petróleo. Por outro lado, a opção de descomissionamento é desprovida de receita até o retorno da plataforma do estaleiro. No que tange à metodologia do presente trabalho, o modelo binomial com probabilidades de risco neutro é aplicado considerando a receita proveniente da produção de petróleo de uma plataforma marítima com sistema de produção flutuante com 14 poços, sendo 10 produtores e 4 injetores e sustentada por 8 linhas de ancoragem. Também é definida a volatilidade do projeto como sendo a volatilidade do preço do petróleo. Por fim, as opções de expansão podem ser exercidas a qualquer momento antes da data de expiração das opções, data esta coincidente para ambas as opções e referente ao término de contrato de afretamento da UMS, que corresponde ao período de cinco anos. Neste período de cinco anos, as duas alternativas são exercidas a partir do primeiro ano, com receitas e custos distintos em virtude das especificidades decorrentes das alternativas tecnológicas propostas. A partir da aplicação do modelo binomial com probabilidades de risco neutro sob o enfoque das opções reais, as duas alternativas tecnológicas são tratadas como opções americanas na avaliação econômica da revitalização e manutenção da plataforma marítima. Também realiza-se a análise tradicional do VPL para as duas alternativas. As duas análises apontam para a escolha da UMS como alternativa ótima de expansão da vida útil da plataforma. Ademais, a análise sob o enfoque das opções reais capta um valor adicional em ambas as alternativas tecnológicas, fruto das características inerentes à indústria petrolífera. Quanto à estrutura do trabalho em questão se divide em cinco capítulos: introdução, referencial teórico, metodologia, apresentação dos resultados e as considerações finais.

Revamping asset quality to maximize income in office markets

We use a unique dataset of c. 2200 commercial towers located in the city of Sao Paulo from 2005:Q3 to 2014:Q3 to study the relationship between asset quality and potential income in different niches of the office market. Our evidence suggests a rent premium in the market for larger office space (corporate) and that building quality is more relevant in this segment. We hypothesize such difference is due to larger competition and commoditization in the market for smaller office space (office) as income in this segment tends to be insensible to different levels of asset quality when we control for spatial variation. We also find that rent premiums associated with building class are monotonically increasing, but not strictly positive across certain quality thresholds. Thus, landlords and developers should take into consideration the market niche and acceptable target building class levels when designing their investment plans in order to maximize income .
