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：Many centralized school admissions systems use lotteries to ration limited seats at oversubscribed schools. The resulting random assignment is used by empirical researchers to identify the effects of schools on outcomes like test scores. I first find that the two most popular empirical research designs may not successfully extract a random assignment of applicants to schools. When are the research designs able to overcome this problem? I show the following main results for a class of data-gene...

摘要：This paper proposes a measure of dissimilarity between stochastic discount factors (SDFs) in different economies. The SDFs are made comparable using the respective bond prices as the numeraire. The measure is dimensionless, synthesizes features of the risk-neutral moments of excess currency returns, and can be extracted from currency option prices. Linking theory to data, we provide evidence gathered from (i) the cross section of 45 currency option prices, (ii) the time series of currency retu...

摘要：Using data from over 300,000 visits to an emergency department (ED), we study the accuracy of gatekeeping decisions-the choices that physicians make regarding patient discharge or admission to the hospital. In our study context, we focus specifically on the effectiveness of a second gatekeeping stage in the ED-a clinical decision unit (CDU). Although only 9.9% of patients in our sample are routed through the CDU, we find that had the unit not been in place during the observation period, the ra...

摘要：Scholars generally assume that consumer ratings reflect consumer satisfaction, but ratings can be influenced by the design of the rating system. We examine two rating designs-single-dimensional rating systems, which elicit overall ratings only, and multidimensional (MD) rating systems, which elicit both dimensional and overall ratings-and how they impact overall ratings. Drawing on the accessibility-diagnosticity framework, we argue that dimensional ratings in MD systems influence overall rati...

摘要：The most important rule to determine payments in real-life bankruptcy problems is the proportional rule. Many such bankruptcy problems are characterized by network aspects, and the values of the agents' assets are endogenous as they depend on the extent to which claims on other agents can be collected. These network aspects make an axiomatic analysis challenging. This paper is the first to provide an axiomatization of the proportional rule in financial networks. Our main axiom is invariance to...

摘要：We investigate a firm's decision to initiate earnings guidance during its first year as a public company following its initial public offering (IPO), which we label early guidance. Using a sample of firms with IPOs between 2001 and 2010, we find that almost 60% provide early guidance and that only one-third of the firms that do not provide guidance during the first year subsequently decide to guide. Consistent with the importance of liquidity incentives following the IPO, we find that firms ar...

摘要：We study the interdependencies between transaction costs, portfolio characteristics, and mutual fund performance. Using a novel data set of actual mutual fund trades, we find that, controlling for investment style, larger funds realize lower percentage transaction costs than smaller funds. Larger mutual funds trade less frequently and hold bigger stocks to actively avoid incurring higher trading costs. Gross returns of larger funds are lower than those of smaller funds due, in part, to the cha...

摘要：Social media platforms for healthcare services are changing how patients choose physicians. The digitization of healthcare reviews has been providing additional information to patients when choosing their physicians. On the other hand, the growing online information introduces more uncertainty among providers regarding the expected future demand and how different service features can affect patient decisions. In this paper, we derive various service-quality proxies from online reviews and show...

摘要：For the first time, new regulatory data allow precise measurement of price discrimination against nonfinancial clients in the foreign exchange derivatives market. Consistent with the theoretical literature, transaction costs vary systematically with measures of client sophistication. The median client pays 10.9 pips more than blue-chip companies because of its lower level of sophistication, which compares with a sample average effective spread of 6.9 pips. However, price discrimination is full...
