摘要：We study the effect of on-the-job experience on base-rate neglect, which is a common bias in assessing conditional probabilities. We do so by carrying out experiments with medical professionals, who are routinely exposed to conditional-probability problems in the form of diagnostic tests, and nonmedical professionals, who are not. As such, medical workers with more years of experience will have had more exposure to base-rate type problems than nonmedical workers with similar years of experienc...

摘要：Exploitation of consumer data allows online retailers to enhance services provided to consumers but at the risk of causing unintended privacy issues. There has been debate about whether to devise regulation policies to restrict data collection and usage by online retailers. This paper studies the implications of newly adopted privacy policies, such as the General Data Protection Regulation (GDPR), for an online retail supply chain comprising a retailer and a supplier. We find that despite the ...

摘要：Although investor attention is fundamental to the efficient functioning of capital markets, it is also an elusive construct that researchers struggle to measure. In recent years, the search volume index (SVI) of ticker searches on Google has become a ubiquitous measure of investor attention, but the amount and effects of measurement error in ticker SVI are unknown. We investigate measurement error in ticker SVI using a data set of 2.7 billion website visits following Standard and Poor's 500 fi...

摘要：Amid an unprecedented loss of biodiversity, a pressing issue is how to improve the efficiency of conservation with limited resources and information. Collecting data on species with a small population is costly and time consuming, and many high-stakes decisions need to be made based on limited data. We develop a partially observable Markov decision processes model with unknown parameters to jointly optimize the information collection and protection efforts for threatened species. The model tak...

摘要：We document strong global commonality in country idiosyncratic return variances across 23 developed markets, which is stronger than international return commonality. The global common factor of idiosyncratic return variances is highly correlated with that of idiosyncratic cash flow variances and is also significantly related to variables capturing aggregate discount rate variation and the conditional market variance. Furthermore, aggregate idiosyncratic return and cash flow variances are mostl...

摘要：More than $60 billion per year in the United States is spent on policies aimed to increase fruit and vegetable (FV) consumption among low-income households. Many of these policy interventions are either monetary (e.g., financial incentives) or education related. The goal of this paper is to improve the performance of these interventions through a more strategic and personalized allocation of funds. This paper introduces a consumer behavioral model for grocery shopping decisions, which is neste...

摘要：This study finds that the requirement of Accounting Standard Codification (ASC) 842 for firms to capitalize operating leases in financial statements beginning in 2019 resulted in firms affected by the standard reducing the reliance on existing debt (debt not associated with the capitalization of operating leases) by 7%-10% on average relative to unaffected firms. We find that firms with greater operating lease capitalization as a result of implementation of ASC 842 have the largest reductions ...

摘要：Fueled by the widespread adoption of algorithms and artificial intelligence, the use of chatbots has become increasingly popular in various business contexts. In this paper, we study how to effectively and appropriately use voice chatbots, particularly by leveraging the two design features identity disclosure and anthropomorphism, and evaluate their impact on the firm operational performance. In collaboration with a large truck-sharing platform, we conducted a field experiment that randomly as...

摘要：We analyze the impact of the 2021 Child Tax Credit (CTC) expansion using detailed transaction data from nearly two million individuals and difference-in-difference analyses around monthly CTC payments. We find that recipients significantly increase their consumption in the week following the payment versus the prior week, with more pronounced effects for lower-income recipients and those with more children. We also find a significant reduction in liquidity constraints for lower-income recipien...
