摘要：The United States spends more than $4 trillion per year on health care, largely conducted by private providers and reimbursed by insurers. A major concern in this system is overbilling and fraud by hospitals, who face incentives to misreport their claims to receive higher payments. In this work, we develop novel machine learning tools to identify hospitals that overbill insurers, which can be used to guide investigations and auditing of suspicious hospitals for both public and private health i...

摘要：A number of large companies deploy facilities-factories, warehouses, shopping malls-that employ thousands of people directly and indirectly. Local governments have been enticing these companies with various financial incentives. But how much economic growth do these facilities promote, if any? We study this question using Amazon distribution facilities as the case in point. We show evidence of a positive effect of opening Amazon's distribution facilities on counties' economic outcomes. We focu...

摘要：Schools often overlook how structuring student and teacher schedules may impact educational outcomes. We analyze the impact of nontraditional school calendars on student and teacher productivity. These calendars differentially allocate mandated instructional time by choosing (1) the number of hours in the school day, (2) the number of school days each year, and (3) the distribution of school days throughout the year. To do this, we use administrative data on over 2 million students and exploit...

摘要：Evaluating the comparative performance of U.S. federal agencies is difficult, particularly since both tasks and missions vary so dramatically. In addition, forces beyond an agency's control (e.g., COVID, an economic downturn, etc.) can determine outcomes even when agencies are performing at a high level. In this paper, we introduce a new approach to measuring organizational performance, something conceptually distinct from, but correlated with, both organizational inputs and outcomes. This mea...

摘要：Many are concerned about the large decline in K-12 student achievement since 2019. And rightly so, given what it signals about student learning and later life outcomes. Less noted is the pre-pandemic sustained decline in student achievement growth that followed more than 30 years of increases. We examine the nature of achievement decline as measured by national and state NAEP scores. Our analysis suggests that pre-pandemic achievement declines are large, began earlier than commonly thought, an...
