摘要：This paper studies a canonical general scheduling model that captures the fundamental trade-off between processing jobs and performing diagnostics (testing). In particular, testing reveals the required processing time and urgency of need-to-schedule jobs to inform future scheduling decisions. The model captures a range of important applications. Prior work focused on special cases (e.g., jobs with independent and identically distributed processing time) to devise optimal policies. In contrast,...

摘要：We measure the willingness to compete of entrepreneurs and salaried workers in an experiment. Participants can choose between a piece rate and a tournament scheme in either private or public. We find that in the private condition, entrepreneurs are less competitive than salaried workers, but in the public condition, this ordering is reversed. Survey data suggest that perceived norms of appropriate behavior, along with beliefs about the instrumental value of competitiveness for professional suc...

摘要：Using a unique data set with detailed information on Danish households and their mortgages, we show that young and old households are more likely to use interestonly (IO) mortgages compared with middle-aged households. Young households use IO mortgages because they expect higher future income and old households because IO mortgages allow them to circumvent an otherwise binding liquidity constraint. Through different channels, IO mortgages thus facilitate consumption smoothing for young and old...

摘要：We study the link between a previously neglected form of intangible firm asset- country reputation-and corporate sales. By exploiting variation in nationalities of foreign victims in local terror attacks, we detect unanticipated distortions in reputations of local countries in foreign countries and we pin down reductions in sales of local country firms in foreign markets. The reductions in sales are economically and statistically significant, persistent, and more pronounced after attacks with ...

摘要：We find evidence for the beta anomaly in mutual fund performance. This anomaly is not accounted for in the standard four-factor framework, nor by the addition of a betting-against-beta factor to the benchmark model. We identify the active component of alpha (active alpha) not attributable to the passive effects related to beta. Active alpha is persistent and associated with superior portfolio performance. We find that, although many investors use standard alpha to allocate capital, a subset of...

摘要：The investment capital asset pricing model, in which expected returns vary cross-sectionally with investment, profitability, and expected growth, provides an equilibrium foundation for Graham and Dodd's security analysis. The q5 model is a good start to explaining prominent security analysis strategies, such as Abarbanell and Bushee's fundamental signals, Frankel and Lee's intrinsic to market, Greenblatt's magic formula, Asness et al.'s quality minus junk, Bartram and Grinblatt's agnostic anal...

摘要：We investigate how market participants price and manage counterparty credit risk using confidential trade repository data on single-name credit default swap (CDS) transactions. We find that counterparty risk has a modest impact on the pricing of CDS contracts but a large impact on the choice of counterparties. For contracts ineligible for central clearing, we show that market participants are significantly less likely to trade with counterparties whose credit risk is highly correlated with the...

摘要：As the prevalence of user-generated reviews has been growing, the pervasiveness of fraudulent reviews has been increasing as well. In an effort to alleviate the consequences of fraudulent reviews, platforms have been using machine-learning algorithms for fraudulent review detection. However, the current business practice of simply removing fraudulent reviews might not be sufficient, as even their temporary presence might forge spillover effects propagating through other shopping tools. In part...
