“…Many scholars argue that this situation is due to several reasons: first, previous studies had much conceptually explained the definitions, purposes, significance and characteristics of the various kinds of performance-based reward in organizations Brown et al, 2010). Second, previous studies had largely utilized a simple survey and correlation analysis method to identify employee perceptions about various types of reward system, as well as simple variance analysis to differentiate the effect of each performance based reward components on various types of performance based reward (Ismail et al, 2011a(Ismail et al, , 2011bMcCausland et al, 2005). Finally, previous studies had much been affected by macro econometric data and statistical formula to design and administer wage and salary system; but these approaches neglect to measure the effect size and nature of performance based reward administration on interactional justice in the reward management research literature Sabeen & Mehboob, 2008;Sogra et al, 2009).…”
