“…Some researchers have argued that non-financial motivators such as "a sense of achievement" and "recognition" are more important than salary in low-income country settings (Alihonou, Soude, & Hounye, 1998;Mathauer & Imhoff, 2006;Stilwell, 2001). However, others point out that in environments where salaries are very low, low motivation is to be expected (Ferrinho, Van Lerberghe, Fronteira, Hipolito, & Biscaia, 2004) and financial incentive schemes have had some success in improving healthworker motivation and performance in low-income country settings (Biai, Rodrigues, Gomes, Ribeiro, Sodemann, Alves et al, 2007;Mliga, 2003;Rodrigues, 1989). Herzberg categorised salary as a "dissatisfier" rather than a "satisfier" (Herzberg, Mausner, & Snyderman, 1959), arguing that low salaries have the potential to demotivate workers but that salary in itself does not motivate workers.…”
