Final answer:
While the required reading does not provide specific phrases matching the question's options, principles of effort and compensation suggest equity as a key element of monetary reward systems, along with efficiency and motivation. The nuances of how rewards affect individuals must also be considered.
Step-by-step explanation:
According to this week's required reading on 'What monetary rewards can and cannot do', two of the five general principles to guide the design of successful monetary reward systems are not directly provided in the options a) Equity and certainty, b) Efficiency and exclusivity, c) Exclusivity and variability, or d) Certainty and variability. However, principles such as effort and compensation suggest that individuals should be rewarded in relation to the effort they put into their work and the costs they incur. The concept of equity, which is fairness in compensation, can be inferred to be a guiding principle based on the reading materials provided.Economic theories such as economic performance, economic freedom, economic efficiency, and the balance between incentives and economic equality also play roles in the design of monetary reward systems.
Monetary rewards have their limitations, and their impact on motivation is particularly nuanced, depending on whether they are expected or come as a surprise.Thus, while the exact answer to the student question may not be provided, understanding monetary reward systems involves balancing various economic principles to achieve the right mix of efficiency, equity, motivation, and economic output.
