Portfolio Delegation and Market Efficiency ∗

چکیده
We develop a two-period general equilibrium model of portfolio delegation with competitive, differentially skilled managers and convex compensation contracts. We show that convex incentives lead to significant equilibrium mispricing, but reduce price volatility. In particular, price informativeness and volatility may exhibit opposite behaviour. Investors do not internalize the externality that their contract choice has on equilibrium prices. As a result, equilibrium incentives may be too strong or too weak and hurt investors as a whole. For example, investors’ utility may be decreasing in the average managers’ skill. Convex incentives amplify this negative externality. Indirect incentives due to future fund flows may induce investors to choose stronger convex direct incentives, amplifying inefficiencies even further. Inference of skill from performance is asymmetric: past bad performance is indicative of low skill, but past good performance is not indicative of high skill. JEL Classification:

The present study is an attempt toward evaluating the performance of portfolios and assets selecting using modified mean-variance models by utilizing a non-parametric efficiency analysis tool, namely Data Envelopment Analysis (DEA). Huge amounts of money are being invested in financial market. As a result, portfolio performance evaluation has created a great deal of interest among people. We kn...
متن کاملRobustness-based portfolio optimization under epistemic uncertainty
In this paper, we propose formulations and algorithms for robust portfolio optimization under both aleatory uncertainty (i.e., natural variability) and epistemic uncertainty (i.e., imprecise probabilistic information) arising from interval data. Epistemic uncertainty is represented using two approaches: (1) moment bounding approach and (2) likelihood-based approach. This paper first proposes a ...
متن کاملRobustness and bootstrap approaches to SSD portfolio efficiency testing
This paper deals with portfolio efficiency testing with respect to second-order stochastic dominance (SSD) criteria. Unlike the pair-wise tests the portfolio efficiency tests allow for full diversification across the assets. As usual in SSD testing, the returns of assets are modeled by scenarios. We apply a computationally attractive method to test whether a US market portfolio, proxied by CRSP...
متن کاملRobust Portfolio Optimization with risk measure CVAR under MGH distribution in DEA models
Financial returns exhibit stylized facts such as leptokurtosis, skewness and heavy-tailness. Regarding this behavior, in this paper, we apply multivariate generalized hyperbolic (mGH) distribution for portfolio modeling and performance evaluation, using conditional value at risk (CVaR) as a risk measure and allocating best weights for portfolio selection. Moreover, a robust portfolio optimizati...
