摘要：Existing literature suggests that hospital occupancy matters for quality of care, as measured by various patient outcomes. However, estimating the causal effect of increased hospital busyness on in-hospital mortality remains an elusive task due to statistical power challenges and the difficulty in separating shocks to occupancy from changes in patient composition. Using data from a large public hospital system in Mexico, we estimate the impact of congestion on in-hospital mortality by exploiti...

摘要：We provide evidence of delayed attention and inaction in response to COVID19 in countries that did not experience SARS in 2003. Using cross-country data, we find that individuals in countries that had SARS infections in 2003 searched more intensively for COVID-19-related information on Google in late January 2020, the time of the first known outbreak in Wuhan, China. Early attention to the novel virus, as measured by Google searches, is associated with deeper stock market drops in countries wi...

摘要：We trace the evolution of research on organizational learning. As organizations acquire experience, their performance typically improves at a decreasing rate. Although this learning-curve pattern is found in many industries, organizations vary in the rate at which they learn. In order to understand this variation, we separate organizational learning into four processes: search, knowledge creation, knowledge retention, and knowledge transfer. Within each process, we present research on how dime...

摘要：We consider a setting in which a nonexclusive reseller procures partially substitutable products from two suppliers, one of whom introduces a direct channel. We find that the presence of the second supplier alters many of the existing results about the interactions between a reseller and an encroaching supplier. For instance, the reseller's and the supply chain's benefit from the direct channel disappears when the product substitutability is sufficiently large. In addition, when the reseller i...

摘要：Theories of organizations are sympathetic to long-standing ideas from network science that organizational networks should be regarded as multiscale and capable of displaying emergent properties. However, the historical difficulty of collecting individuallevel network data for many (N >> 1) organizations, each of which comprises many (n >> 1) individuals, has hobbled efforts to develop specific, theoretically motivated hypotheses connecting micro- (i.e., individual-level) network structure with...

摘要：We consider a large decentralized freelance platform where buyers with private information about their quality preferences are matched with freelancers that differ in quality. When posting their job requests, buyers can report their quality preferences via cheap talk, which influences freelancers' application and pricing strategies. By exaggerating one's quality preference, a buyer attracts not only more applications from freelancers, but also those with higher quality, at the cost of a higher...

摘要：Retailers use lenient return policies to stimulate demand and increase revenues, as such policies help customers assess uncertain product valuations at low (or no) return cost and yield higher equilibrium prices. However, generous refunds also yield unintended consequences such as opportunistic returns, which take place when customers intentionally rent a product for short-term use. Accounting for 11% of all product returns in the United States in 2017, opportunistic returns prompt retailers t...

摘要：In this paper, I provide some observations on how the academic field of operations management has changed over the past 40 years. For this purpose, I have identified and classified the operations management (OM) papers published in Management Science in 1976 and in 2016. From this review, I comment on what's changed, what's new, and what we might see in the future. In reflecting on these changes, I also document and discuss how the OM editorial structure and mission have evolved at Management ...
