摘要:Two-stage screening programs for colorectal cancer (CRC) detection typically involve a first-stage test that evaluates fecal-hemoglobin (f-Hb) concentration in stool samples, with positive results leading to a recommended second-stage diagnostic test (colonoscopy). We explore the design of the first-stage test-specifically the selection of f-Hb cutoffs to report test outcomes-to balance screening effectiveness (CRC and polyp detection) and efficiency (colonoscopy costs), considering that not a...

摘要:GAAP's Management Approach to segment reporting (ASC 280) requires firms to report segment profit/loss as the measure managers use when allocating resources internally across segments under the assumption that investors benefit from viewing segment performance through the eyes of management. We examine how segment performance measurement aligns with the way that investors use segment profit/loss measures externally. We first survey professional investors and find that they primarily use segmen...

摘要:Marketers rely on various online advertising channels to reach customers and are increasingly interested in multi-touch attribution, which evaluates the contribution of each touchpoint to a conversion. However, as the numbers of marketing channels and touchpoints increase, the attribution challenge becomes more intricate because of the complex interplay among different touchpoints within and across channels. Utilizing customer path-to-purchase data, this article addresses this challenge by dev...

摘要:This paper studies the impacts of financial shocks on firm insurance, firm dynamics, and macroeconomic implications. A key departure from the literature is that firms provide wage insurance contracts to risk-averse workers in a long-term relationship. Such contracts endogenously impose a form of inflexible debt liability to firms, and make firms with limited financial net worth more vulnerable to shocks than others. In our model, firms have heterogenous productivity and financial net worth, an...

摘要:We consider the common setting where one observes a large number of opinionated text documents and related covariates, such as the text of online reviews along with the date of the review and the author demographic information. In this setting it can be of interest to understand how the covariates determine the text composition, as well as the prevalence, sentiment, and/or discourse of various discussion themes. Yet, most topic modeling methods in the machine learning literature are designed t...

摘要:We consider the problem of managing resources in shared micromobility systems (bike sharing and scooter sharing). An important task in managing such systems is periodic repositioning/recharging/sourcing of units to avoid stockouts or excess inventory at nodes with unbalanced flows. We consider a discrete-time model; each period begins with an initial inventory at each node in the network, and then, customers (demand) materialize at the nodes. Each customer picks up a unit at the origin node an...

摘要:The racial disparity in mortgage approval rates decreases by four percentage points as a result of hedge fund activism targeting banks. Target banks experience a higher turnover of mortgage officers and open new bank branches in areas with greater racial disparities in mortgage approval rates. We show that the results are driven by hedge fund activists' efforts to increase profitability and comply with the community reinvestment act. Our results suggest that hedge funds' incentives to maximize...

摘要:The shift to a service-oriented economy has driven traditional product-oriented manufacturing firms to integrate various services into their businesses. This study aims to provide empirical evidence on how manufacturers' service offerings impact demand variability and intrafirm bullwhip effects. Through bag-of-words text mining on 10-K filings of U.S.-listed manufacturing firms, we propose a novel measurement to identify annual services offered. We validate the measurement's statistical and ec...

摘要:Mediation (assisted negotiation) is the preferred alternative dispute resolution approach that has given rise to a multibillion-dollar industry worldwide. Online dispute resolution (ODR) providers rely heavily on mechanized e-negotiation systems. Inspired by their structured negotiation systems, we follow a market design approach and develop a tractable framework in search of strategy-proof, efficient, and individually rational mediation mechanisms. We characterize the full family of such mech...
