A novel multivariate factor GARCH specification is used to obtain conditional covariance matrices of minimum variance portfolios containing a very large number of assets. The approach allows for time varying factor loads, and achieves great flexibility by allowing alternative specifications for...

The predictive power of recently introduced components affecting correlations is investigated. The focus is on models allowing for a flexible specification of the short-run component of correlations as well as the long-run component. Moreover, models allowing the correlation dynamics to be...

Given the importance of accurate performance evaluation for the banking industry, this paper uses data on Taiwanese domestic banks and investigates whether it is useful to construct an integrated performance model in order to address the problems of efficiency-analysis with the aid of an...

The emergence of the internet has forced a wealth of firms to explore a new form of channels of distribution, i.e., internet channels. Managing the impact of introducing an internet channel into an existing distribution system is probably one of the greatest challenges today. This research...

This paper presents an exploratory study of service productivity index (SPI). Given the weakness of the previous service productivity measurements, this paper presents an improvement in measuring service productivity. With regard to the basic principal of productivity, it is proposed to measure...

Tenix won the ANZAC Ship Contract in November 1989 to build ten guided missile frigates for the navies of Australia and New Zealand. The ships are planned to have a service life of 25 to 30 years. Within this time period, there will be changes in the operational requirements for these vessels....

The economy has undergone a profound structural transformation in the last two decades. The Information Technology (IT) revolution has expanded well beyond the cutting-edge high-tech sector redefining the rules of global competition. In general, a direct correlation between IT spending and...
