One problem with boni is that they become mali if one does not get what one expects. This is especially problematic when it affects the better part of a company's workforce. Then the company is demotivating their best employees. A related hypothesis: There is an asymmetry because overvaluations do not have an equivalent motivating effect as undervaluations have a demotivating effect. Boni without an objective measure are therefore on average rather demotivating.
