Final answer:
Arvid's boss uses a fixed ratio reinforcement schedule to motivate the workers, where a bonus is awarded for selling more than 30 smoothies, prioritizing quantity of sales to encourage higher productivity.
Step-by-step explanation:
Arvid's boss is primarily using a fixed ratio reinforcement schedule to incentivize employees at the new smoothie shop. Similar to the example where Carla earns a commission for each pair of glasses sold, Arvid and his coworkers will receive a bonus for every sale beyond the threshold of 30 smoothies. The bonus serves as a direct reward for the quantity of smoothies sold, aiming to boost productivity and sales within the shop.
The quality of the smoothies isn't the focus of this reinforcement schedule; instead, it emphasizes quantity to achieve a higher productivity. However, in workplaces that operate in competitive markets, employers often have an incentive to make decisions based on economic factors, such as paying a wage based on productivity. If workers are rewarded for their productivity, they'll potentially be more efficient and effective, aligning with the overall goal of a profit-maximizing firm which hires workers up to the point where the marginal revenue product equals the market wage, as detailed in the provided information.
