Suppose Yi is an estimator or sufficient statistic for a location parameter [theta]i (i = 1,...,k) of a location family. Let [theta](1) [less-than-or-equals, slant] 0(2) [less-than-or-equals, slant] ··· [less-than-or-equals, slant] [theta](k) be the ordered parameters. This paper deals...

Recently, as an alternative to the GARCH model, the autoregressive random variance (ARV) model has been gaining popularity in the modelling of changing volatility, mainly because of the capability in capturing the stochastic nature of volatility. This article highlights the ARV model as an...

"This paper investigates the volatility persistence, volatility variability from day to day and transmission of volatility in seven Southeast Asian stock markets from 1980 to 1991 using the ARV approach. We found strong evidence that shocks to volatility are persistent in Taiwan. Moreover, the...

Suppose that we have k candidates in an election and that the top m winners will be elected. Assume that the voters can select up to m (

In the presence of transaction cost, the ‘perfect’ timing strategy which holds stocks in a period with positive excess return and holds cash in a period with negative excess return is not necessarily perfect. Using the optimal growth criterion, this paper derives the truly perfect timing...

In this paper, we consider the pair of symmetric dual multiobjective variational mixed integer programs proposed by Chen and Yang [X. Chen, J. Yang, Symmetric duality for minimax multiobjective variational mixed integer programming problems with partial-invexity, European Journal of Operational...

Retailing channels are increasingly being dominated by 'power' retailers who are in a position to dictate prices and ordering schedules to manufacturers and suppliers. A dominant retailer, such as Wal-Mart, has the 'power' to decide retail prices of products because there are so many...
