Diversification-consistent DEA-risk tests – solution techniques and an empirical comparison
نویسنده
چکیده
In this paper, we will propose numerically tractable formulations of the diversification-consistent DEA tests, which generalize traditional DEA tests as well as mean-risk models. We employ general deviation measures to measure risk of the investment opportunities. We will compare strength of the tests and give characterizations of efficient and inefficient investment opportunities. US industry representative portfolios will be ranked using the proposed DEA tests.

Influence of short sales and margin requirements on portfolio efficiency - a DEA-risk approach
We focus on efficiency of assets and portfolios available to investors on financial markets. We employ diversification consistent DEA-risk models with CVaR deviations as the inputs and expected rate of return as the output. Moreover, we allow short selling and take into account margin requirements. Our model is then employed in an empirical study where selected assets from US stock market are i...
متن کاملData envelopment analysis of mutual funds based on second-order stochastic dominance
Although data envelopment analysis (DEA) has been extensively used to assess the performance of mutual funds (MF), most of the approaches overestimate the risk associated to the endogenous benchmark portfolio. This is because in the conventional DEA technology the risk of the target portfolio is computed as a linear combination of the risk of the assessed MF. This neglects the important effects...
متن کاملAn Empirical Comparison of Distance Measures for Multivariate Time Series Clustering
Multivariate time series (MTS) data are ubiquitous in science and daily life, and how to measure their similarity is a core part of MTS analyzing process. Many of the research efforts in this context have focused on proposing novel similarity measures for the underlying data. However, with the countless techniques to estimate similarity between MTS, this field suffers from a lack of comparative...
متن کاملInternationalization and Bank Risk
This paper documents a positive relation between internationalization and bank risk. This is consistent with the empirical dominance of the market risk hypothesis – whereby internationalization increases banks’ risk due to market-specific factors – over the diversification hypothesis – whereby internationalization allows banks to reduce risk through increased diversification of their operations...
