摘要:Many firms conduct A/B tests to find a marketing action that improves a value of interest, such as revenue or profit. We develop the asymptotic minimax regret (AMMR) criterion, a practical decision-theoretic approach for choosing among binary marketing actions based on A/B tests. The AMMR is a general large-sample approximation of the minimax-regret criterion from a frequentist standpoint. Our method directly optimizes the decision-relevant metric, accounting for the product of the error proba...

摘要:We propose a financial statement (FS) fraud detection framework, called PeerMeta, that makes improvements in all three components of the detection procedure: label measurement, feature set, and detection model. For the label measurement, prior studies mainly adopt FS fraud events that have already been disclosed and confirmed. We construct a new measure based on news coverage that can reflect unrevealed FS fraud behaviors as well. For the feature set, we innovatively add peer factors learned t...

摘要:This paper explores the connection between tenant riskiness, commercial lease length, and the term structure of lease contracts. Theory shows that the possibility of default on a long-term lease generates a risk/lease-length connection. The empirical work uses a large CompStak lease data set combined with tenant characteristics (including risk) from Dun & Bradstreet (D&B). Regressions show that lease length is inversely related to the D&B risk measures, as predicted, and that risky tenants pay...

摘要:In this article, we investigate how information about production externalities, such as ecolabels, can be presented to create market pressure on firms to reduce these externalities. Specifically, we explore whether integrating information on externalities with consumer product ratings into a single combined rating can generate pressure to reduce externalities from all consumers, not just environmentally conscious ones. Theoretically, we demonstrate the existence of an equilibrium where produce...

摘要:Effective information sharing is critical for the success of organizations and governments. Because information that is easy to access is more likely to be adopted, leaders often minimize friction in information delivery. However, one type of friction may increase engagement: piquing curiosity by posing relevant questions prior to sharing information. To test this, we shared identical information about COVID-19 in either question-andanswer format or via direct statements across two preregister...
