A comprehensive empirical analysis of the return and conditional variance of Tel Aviv Stock Exchange (TASE) indices is performed using GARCH models. The prediction performance of these conditional changing variance models is compared to newer asymmetric GJR and APARCH models. We also quantify...

Yitzhaki (1996) showed that the OLS estimator of the slope coefficient in a simple regression is a weighted average of the slopes delineated by adjacent observations. The weights depend only on the distribution of the independent variable. In this paper I demonstrate that equal weights can only...

Stochastic dominance rules provide necessary and sufficient conditions for characterizing efficient portfolios that suit all expected utility maximizers. For the finance practitioner, though, these conditions are not easy to apply or interpret. Portfolio selection models like the mean-variance...

This paper compiles the risk measures associated with the Lorenz curve. The Lorenz curve is the main tool in economics for measuring income distribution and inequality. For the past decades some of the Lorenz curve spin-offs have been used in risk analysis and finance. In particular, the Lorenz...
