摘要：We examine a prevalent form of client-agent interaction through a feedback-giving game. In this game, a client undertakes a nontrivial task and is compensated based on her task performance, which is only made known to her when the client-agent interaction ends. Meanwhile, her performance is disclosed to an agent, who must then give the client feedback on her performance. Upon receiving the feedback, the client reports her happiness level, which in turn determines the agent's payoff. In eight s...

摘要：To explore the effects of different incentives on crowdsourcing participation and submission quality, we conduct a randomized field experiment on Taskcn, a large Chinese crowdsourcing site using mechanisms with features of an all-pay auction. In our study, we systematically vary the size of the reward as well as the presence of a soft reserve, or early high-quality submission. We find that a higher reward induces significantly more submissions and submissions of higher quality. In comparison, ...

摘要：Mobile technologies enable marketers to target consumers by time and location. This study builds on a large-scale randomized experiment of short message service (SMS) texts sent to 12,265 mobile users. We draw on contextual marketing theory to hypothesize how different combinations of mobile targeting determine consumer responses to mobile promotions. We identify that temporal targeting and geographical targeting individually increase sales purchases. Surprisingly, the sales effects of employi...

摘要：Motivated by the availability of real-time data on customer characteristics, we consider the problem of personalizing the assortment of products for each arriving customer. Using actual sales data from an online retailer, we demonstrate that personalization based on each customer's location can lead to over 10% improvements in revenue compared to a policy that treats all customers the same. We propose a family of index-based policies that effectively coordinate the real-time assortment decisio...

摘要：The use of global suppliers has increased considerably over the last three decades. Operations management theory establishes that global sourcing requires more units of inventory, but since these units are often procured at a lower cost from global suppliers the capital invested in inventory and the consequent financial burden may increase or decrease with global sourcing. This study provides rigorous firm-level empirical evidence that links the global sourcing practices of public U. S. firms ...

摘要：We present a model of optimal allocation to liquid and illiquid assets, where illiquidity risk results from the restriction that an asset cannot be traded for intervals of uncertain duration. Illiquidity risk leads to increased and state-dependent risk aversion and reduces the allocation to both liquid and illiquid risky assets. Uncertainty about the length of the illiquidity interval, as opposed to a deterministic nontrading interval, is a primary determinant of the cost of illiquidity. We al...

摘要：This paper presents theory and experiments where people's prosocial attitudes fluctuate over time following the violation of an internalized norm. We report the results of two experiments in which people who first made an immoral choice were then more likely to donate to charity than those who did not. In addition, those who knew that a donation opportunity would follow the potentially immoral choice behaved more unethically than those who did not know. We interpret this increase in charitable...

摘要：Taking advantage of recently augmented corporate bond transaction data, we examine the pricing implications of informed trading in corporate bonds and its ability to predict corporate defaults. We find that microstructure measures of information asymmetry seem to capture adverse selection in corporate bond trading reasonably well. We demonstrate that information asymmetry in bond trading has explanatory power for corporate bond yield spreads, and this result holds after controlling for the tra...

摘要：We consider Cournot competition in the presence of congestion effects. Our model consists of several service providers with differentiated services, each competing for users who are sensitive to both price and congestion. We distinguish two types of congestion effects, depending on whether spillover costs exist, that is, where one service provider's congestion cost increases with the other providers' output level. We quantify the efficiency of an unregulated oligopoly with respect to the optim...

摘要：We propose an approach for using individual-level data on social interactions (e. g., number of recommendations received by consumers, number of recommendations given by adopters, number of social ties) to improve the aggregate penetration forecasts made by extant diffusion models. We capture social interactions through an individual-level hazard rate in such a way that the resulting aggregate penetration process is available in closed form and nests extant diffusion models. The parameters of ...
