摘要：We examine the impact of social investing on charitable donations using a unique data set consisting of investment behaviors and donation transactions for more than 10,000 customers of an investment app platform. We find that investors switching to a recently introduced social fund reduced their donations, mainly in charities supporting causes similar to those of the social fund. However, 79% of the investors that switched to the social fund did not donate before switching, so the social fund ...

摘要：Decision makers often want to target interventions so as to maximize an outcome that is observed only in the long term. This typically requires delaying decisions until the outcome is observed or relying on simple short-term proxies for the long-term outcome. Here, we build on the statistical surrogacy and policy learning literatures to impute the missing long-term outcomes and then approximate the optimal targeting policy on the imputed outcomes via a doubly robust approach. We first show tha...

摘要：We explore the statistical and economic importance of restrictions on the dynamics of risk compensation from the perspective of a real-time Bayesian learner who predicts bond excess returns using dynamic term structure models (DTSMs). The question on whether potential statistical predictability offered by such models can generate economically significant portfolio benefits out-of-sample is revisited while imposing restrictions on their risk premia parameters. To address this question, we propo...

摘要：Folklore suggests that policy gradient can be more robust to misspecification than its relative, approximate policy iteration. This paper studies the case of state-aggregated representations, in which the state space is partitioned and either the policy or value function approximation is held constant over partitions. This paper shows a policy gradient method converges to a policy whose regret per period is bounded by epsilon, the largest difference between two elements of the state-action val...

摘要：Using an administrative payroll data set for 2.6 million retail workers, we find that the staggered rollout of a major e-commerce firm's fulfillment centers reduces traditional retail workers' income in geographically proximate counties by 2.4%. Wages of hourly workers, especially part-time hourly workers, decrease significantly driven by a drop in the number of hours worked. We observe a U-shaped pattern in which both young and old workers experience a sharper decrease in wage income. Consequ...

摘要：We consider a dynamic pricing problem in which a firm sells one item to a single buyer to maximize expected revenue. The firm commits to a price function over an infinite horizon. The buyer arrives at some random time with a private value for the item. He is more impatient than the seller and strategizes over the timing of the purchase in order to maximize his expected utility, which implies either buying immediately, waiting to benefit from a lower price, or not buying. We study the value of ...

摘要：Models of statistical discrimination typically assume that employers make rational inference from (education) signals. However, there is a large amount of evidence showing that most people do not update their beliefs rationally. We use a model and two experiments to show that employers who are conservative, in the sense of signal neglect, discriminate more against disadvantaged groups than Bayesian employers. We find that such non-Bayesian statistical discrimination deters high-ability workers...

摘要：Effective treatment of Parkinson's disease (PD) is a continual challenge for healthcare providers, and providers can benefit from leveraging emerging technologies to supplement traditional clinic care. We develop a data-driven reinforcement learning (RL) framework to optimize PD medication regimens through wearable sensors. We leverage a data set of n = 26 PD patients who wore wrist-mounted movement trackers for two separate six-day periods. Using these data, we first build and validate a simu...

摘要：As the industrial Internet-of-things (IIoT) is becoming increasingly valuable, manufacturers are eager to establish IIoT-based platforms for preventative maintenance (PM). These platforms reposition the roles of manufacturers and reshape the patterns of the after-sales service market. Manufacturers can adopt either the competitive strategy by introducing improved after-sales services to compete with independent maintenance, repair, and operations firms (MROs) or the coopetitive strategy by sim...

摘要：Counterfeits are available across many marketplaces. In emerging markets, in particular, consumers often observe a mix of counterfeits and authentic products sold by retailers. It is difficult for some consumers to distinguish between the two types of products. From these consumers' perspective, the products can be considered as probabilistic goods, and we term retailers' strategies probabilistic selling of counterfeits. Retailers who sell counterfeits are subject to a penalty by regulation. W...
