  Commonwealth Bank of Australia: Unbanklike Experimentation

  Ryan W. Buell and Leslie K. John

  In August 2017, Commonwealth Bank of Australia was looking for ways to differentiate itself from competing banks, and was also trying to improve the financial wellbeing of its customers. One domain where this was particularly relevant was in its bank-issued credit card business, where customers routinely selected cards that although profitable for the bank could be a poor fit for customers’ needs – leading to low satisfaction scores, cancellations, and occasionally, financial distress. To that end, the company’s Behavioral Economics team had developed a provocative experiment dubbed “The Good and the Bad.” Rather than just presenting the strengths of its various credit card offerings, they proposed also promoting each credit card’s less-obvious drawbacks. Being transparent with customers might help them make better choices, but would those choices come at the expense of bank performance? Should a company choose to be in the sales prevention business?

  Discretionary Task Ordering: Queue Management in Radiological Services

  Maria Ibanez, Jonathan R. Clark, Robert S. Huckman and Bradley R. Staats

  Work-scheduling research typically prescribes task sequences implemented by managers. Yet employees often have discretion to deviate from their prescribed sequence. Using data from 2.4 million radiological diagnoses, we find that doctors prioritize similar tasks (batching) and those tasks they expect to complete faster (shortest expected processing time). Moreover, they exercise more discretion as they accumulate experience. Exploiting random assignment of tasks to doctors’ queues, instrumental variable models reveal that these deviations erode productivity. This productivity decline lessens as doctors learn from experience. Prioritizing the shortest tasks is particularly detrimental to productivity. Actively grouping similar tasks also reduces productivity, in stark contrast to productivity gains from exogenous grouping, indicating deviation costs outweigh benefits from repetition. By analyzing task completion times, our work highlights the tradeoffs between the time required to exercise discretion and the potential gains from doing so, which has implications for how discretion over scheduling should be delegated.
