摘要：Within the affine framework, many have observed a tension between matching conditional first and second moments in dynamic term structure models (DTSMs). Although the existence of this tension is generally accepted, less understood is the mechanism that underlies it. We show that no arbitrage along with the rich information in the cross section of yields has strong implications for both the dynamics of volatility and the forecasts of yields. We show that this link implied by the absence of arb...

摘要：The shortest-remaining-processing-time (SRPT) scheduling policy has been extensively studied, for more than 50 years, in single-server queues with infinitely patient jobs. Yet, much less is known about its performance in multiserver queues. In this paper, we present the first theoretical analysis of SRPT in multiserver queues with abandonment. In particular, we consider the M/GI/s + GI queue and demonstrate that, in the many-sever overloaded regime, performance in the SRPT queue is equivalent,...

摘要：In over-the-counter markets for assets, such as bonds and securitizations, large volumes can be split into smaller pieces and gradually sold to several final investors with the intermediation of multiple dealers. This paper proposes a model to study this process, called asset dissemination. A dealer buys several units of an asset from a customer and then sells some units to the dealer's customers and to a second dealer, who sells to the second dealer's customers and to a third dealer, and so o...

摘要：Experiments detecting ambiguity aversion often rely on the assumption that probabilities are exogenously given for some uncertain events. However, the canonical models that accommodate ambiguity into economic theory, such as the maxmin expected utility (MEU) and Choquet expected utility (CEU) models, are purely subjective. These models do not specify how subjects could incorporate exogenous probabilities into decisions. We study two approaches for embedding exogenous probabilities in the conte...

摘要：Using a newly assembled 50-country firm-level database spanning 19 years, we document a bright side for employees of business group-affiliated firms: less pronounced fluctuations in employment than unaffiliated firms in response to macroeconomic shocks. The results are robust to a variety of tests designed to mitigate endogeneity concerns, including propensity score matching and comparisons of successful and failed group integrations, and are present in both booms and recessions. Our results a...

摘要：Most online content publishers have moved to subscription-based business models regulated by digital paywalls. But the managerial implications of such freemium content offerings are not well understood. We, therefore, utilized microlevel user activity data from the New York Times to conduct a large-scale study of the implications of digital paywall design for publishers. Specifically, we use a quasi-experiment that varied the (1) quantity (the number of free articles) and (2) exclusivity (the ...

摘要：We analyze the bidding behavior of expectations-based loss-averse bidders in auctions with interdependent values. We emphasize the difference between the risk bidders face over whether they win the auction (extensive risk) and the risk they face over the value of the prize conditional on winning (intensive risk). The extensive risk creates an attachment effect, whereas the intensive risk operates via a comparison effect. How loss-averse bidders react to these different risks depends on whether...

摘要：In November 2011, the U.S. Securities and Exchange Commission implemented the final provision of Rule 15c3-5 curbing unfiltered market access. The provision mandated that brokers verify their clients' order flow for compliance with credit and capital thresholds before routing to market centers. We find that the new checks introduce latency to order flow and force some latency-sensitive strategies out of the market. As a result, liquidity providers are better able to revise their quotes in resp...

摘要：General hospitals across the world are becoming larger (i.e., admitting more patients each year) and more complex (i.e., offering a wider range of services to patients with more diverse care needs). Prior work suggests that an increase in patient volume in a hospital service is associated with reduced costs per patient in that service. However, it is unclear how volume changes in one service affect the costs of the other services in the same hospital. This paper investigates such volume-cost s...
