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...

"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...

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...

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...

This study presents several revenue optimisation models for hotel room reservations for a future target day with multiple-day stays. Assume that the hotel has only one type of room but the unit rate for the room may be different during every booking period and every reservation may cover several...
