Local-Thinking Bias

The Accounting Review 2025 100(6), 87-112 open access
ABSTRACT Local-thinking bias, wherein agents overweight information that comes readily to mind, is a prominent finding in cognitive psychology. In this study, we investigate local-thinking bias in the context of sell-side analysts and measure each analyst’s “local” information as news stemming from their individual coverage portfolio. Tests examining multiple analysts forecasting on the same focal firm at the same time find that individual analysts overweight idiosyncratic local news and underweight news from economically linked firms that are not in their coverage portfolios. Market prices track the analyst bias from local news, leading to predictable and economically significant return reversal patterns in the future. A trading strategy that adjusts for analysts’ biases earns meaningful abnormal returns. We discuss the implications of these findings for three literatures: (1) cognitive psychology, (2) analyst behavior, and (3) behavioral asset pricing.

The Effects of Relative Performance Information and Work-Training Tradeoff on Employees’ Skill Development: An Experimental Investigation

The Accounting Review 2025 100(3), 35-58 open access
ABSTRACT Employees’ skill development is key to organizations’ competitiveness in a global, knowledge-based economy. Prior research in accounting, however, has mainly focused on motivating the provision of transitory effort. This study investigates how relative performance information (RPI) as a management control influences employees’ willingness to engage in skill development and whether the effect of RPI depends on whether employees face a tradeoff between training and current work performance. We predict and find that RPI increases the likelihood of taking training when a work-training tradeoff is absent but decreases it when a work-training tradeoff is present. We also predict and find RPI increases employee performance when a work-training tradeoff is absent and the effect is less positive (and directionally negative) when a work-training tradeoff is present. Our paper is an important first step in investigating how management controls interfere with employees’ investment in skill development and its tradeoff with transitory effort provision.

Ambulance Taxis: The Impact of Regulation and Litigation on Health-Care Fraud

Journal of Political Economy 2025 133(5), 1661-1702 open access
We study the effectiveness of pay-and-chase lawsuits and upfront regulations for combating health care fraud. Between 2003 and 2017, Medicare spent $7.7 billion on 37.5 million regularly scheduled ambulance rides for patients traveling to and from dialysis facilities even though many did not satisfy Medicare's criteria for receiving reimbursements. Using an identification strategy based on the staggered timing of regulations and lawsuits across the US, we find that adding a prior authorization requirement for ambulance reimbursements reduced spending much more than pursuing criminal and civil litigation did on their own. We find no evidence that prior authorization affected patients' health.
