International E-Banking: ICT Investments and the Basel Accord

This study investigates how the Basel Accord and Information and Telecommunications Technologies (ICT) investments affect the commercial banking industries across countries. We employ the stochastic frontier approach to explore a data set composed of commercial banks from 51 countries. We find that telecommunications investment reduces, and the Basel Accord proxy enhances, the cost efficiency of commercial banks under study. Moreover, it is found that ICT investments improve cost efficiencies of commercial banks for countries in which the regulations are consistent with the international supervision

Relative Sizes of Information Technology Investments and Productive Efficiency: Their Linkage and Empirical Evidence

The contribution of information technology (IT) to organizational performance has been investigated extensively in recent IS research. A number of economic and financial measures have been employed by researchers to gauge the impact of IT on organizational performance. The results of previous research can be described as inconclusive at best. This paper uses stochastic frontiers to examine the relationship between the relative size of IT investments by firms and their productive efficiency in the production process. Assuming different production frontiers (including the popular generalized Cobb-Douglas, the more general Box-Cox transformation, and the most general Box-Tidwell transformation for the production process), we find consistent empirical evidence that the relative level of IT investments has a positive effect on the firm\u27s productive efficiency, implying that firms investing comparatively more in IT are likely to be more efficient in their production processes than those investing less. This study confirms the positive effect of IT on the firm\u27s efficiency in the production process, provides a source to explain the disappearance of the productivity paradox, and suggests a direction for future research that may integrate both economic and financial aspects of previous research on IT benefits

The Relationships Among Managerial Discretion, Firm Performance, And Chief Executive Officer Compensation: A Simultaneous Equations System Approach

Prior executive compensation studies overlooked the endogeneity of firm performance and the simultaneity of managerial discretion, firm performance, and CEO pay. To overcome these two shortcomings, we propose a novel simultaneous equations system model to investigate the cause-and-effect relationships among research & development (R&D), advertising, firm performance, and CEO compensation, which are jointly affected by CEO’s tenure, age, ownership, firm size, risk, and industry. Although the feedback loops are positive between firm performance and CEO pay and between advertising and firm performance, the feedback loop is negative between R&D and firm performance. Firm size has a direct and indirect effect on R&D, advertising, firm performance, and CEO pay. Large firm size may entice CEOs to invest excessively in R&D, leading to poor performance and low pay. Our study implies that the positive relationship between firm performance and CEO pay depends upon the appropriateness of the strategic choices that CEOs make

An econometric analysis of the desktop computer hardware market

The purpose of this study was to compare six competing econometric models which depict the relationship between hardware characteristics and machine cost for the desktop computer market. The Box-Cox methodology and multiyear data were used to facilitate this comparison. The analysis validated that the Box-Cox methodology is a viable means for evaluating competing model formulations within the field of information systems research. The results were consistent with past research that suggested a double natural log model formulation for representing the functional relationships among variables when modeling machine cost as a function of hardware attributes. Further, the more complex power transformation model formulations suggested by the Box-Cox methodology did not significantly outperform the more traditional and simpler double natural log model. More specifically, the results indicated that variables related to primary memory and microchip tedinology have the largest impact on machine cost. Additionally, variables related to madiine connectivity, machine expandability, and year of observation were also found to be significant explanatory variables for machine cost

Scheduling with Sequencing Flexibility *

This study examines the effects of sequencing flexibility on the performance of rules used to schedule operations in manufacturing systems. The findings show that taking advantage of even low levels of sequencing flexibility in the set of operations required to do a job results in substantial improvement in the performance of scheduling rules with respect to mean flowtime. Differences in the mean flowtime measure for various rules also diminish significantly with increasing sequencing flexibility. Performance improvements additionally result for such due-date related performance measures as mean tardiness and the proportion of jobs tardy. At high levels of sequencing flexibility, some nonparametric scheduling rules outperform the shortest processing time rule in terms of the mean flowtime criterion. Rules based on job due dates also outperform rules based on operation milestones in terms of tardiness related criteria at high levels of sequencing flexibility. The implications of these findings for the design of manufacturing systems and product design are noted.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/73893/1/j.1540-5915.1993.tb00477.x.pd

Measurement of the cross-section and charge asymmetry of WW bosons produced in proton-proton collisions at s=8\sqrt{s}=8 TeV with the ATLAS detector

This paper presents measurements of the $W^+ \rightarrow \mu^+\nu$ and $W^- \rightarrow \mu^-\nu$ cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS experiment at the LHC and correspond to a total integrated luminosity of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the 1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured with an uncertainty between 0.002 and 0.003. The results are compared with predictions based on next-to-next-to-leading-order calculations with various parton distribution functions and have the sensitivity to discriminate between them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables, submitted to EPJC.
