摘要：The growing market for retail structured investment products and empirical evidence for excessive pricing of such products raise the hypothesis that private investors show increased risk appetite in structured investment contexts. A two-stage framed field experiment building on cumulative prospect theory is designed to test this hypothesis. Subjects' expectations regarding the future performance of an underlying index are elicited first. A bisection algorithm is then applied to derive the cert...

摘要：We investigate what fraction of all significant results in website A/B testing is actually null effects (i.e., the false discovery rate (FDR)). Our data consist of 4,964 effects from 2,766 experiments conducted on a commercial A/B testing platform. Using three different methods, we find that the FDR ranges between 28% and 37% for tests conducted at 10% significance and between 18% and 25% for tests at 5% significance (two sided). These high FDRs stem mostly from the high fraction of true null ...

摘要：We consider an online assortment optimization problem where we have n substitutable products with fixed reusable capacities c(1), ...,c(n). In each period t, a user with some preferences (potentially adversarially chosen) who offers a subset of products, S-t, from the set of available products arrives at the seller's platform. The user selects product j is an element of S-t with probability given by the preference model and uses it for a random number of periods,(t) over tilde (j), that is dis...

摘要：We analyze demand information sharing collaboration between two manufacturers and a retailer under upstream competition. The manufacturers produce partially substitutable products, which are stocked by the retailer that sells them in the market characterized by random demand. The manufacturers are privately informed about uncertain demand and decide on whether to share this information with the retailer. We show that by not sharing information, a manufacturer ends up distorting its wholesale p...

摘要：We study the effects of village credit information sharing on individual microloan repayment, using a randomized experiment with loan applicants from 40 villages in rural China. In our main treatment, customers received a message on the loan application form that overdue payment (40 days after each installment due date) will be considered for public disclosure among the village by showing debtors' names on a blackboard outside the village office of the microlending institution. On average, thi...

摘要：Most retailers today sell products through an online channel in addition to traditional physical stores. We investigate how such a multichannel or omnichannel retailer should decide the number and size of physical stores. We show that a higher return rate for online purchases can incentivize the retailer to have fewer physical stores that are larger in size. As online shopping becomes more convenient, a retailer may prefer to have more physical stores that are smaller in size. We also study th...

摘要：Although innovation sharing between a buyer and a supplier-a common practice in the automotive industry-can increase the efficiency and total profit of a supply chain, suppliers are often reluctant to do so. Sharing innovations would leave the supplier in a vulnerable position if the buyer were to exploit the information (e.g., by resharing the supplier's innovation with competing suppliers). Anecdotal evidence from automotive suppliers tells us that the nature of a supplier-buyer relationship...

摘要：We study the optimal contracting problem with subjective evaluation when the principal can ask the agent to revise his work. The possibility of revision benefits the principal by providing the option value of making another attempt at the work. However, it also introduces a new type of incentive problem for the principal: she may ask for revision even if it is inefficient to do so. This new incentive issue for the principal also affects the incentive of the agent: he may procrastinate his effo...

摘要：This paper estimates the heterogeneity in peer effects among research scientists in terms of network position. I propose a new measure, brokerage degree, that determines the extent to which a scientist depends on a coauthor to provide him unique access to other scientists further away. I apply this measure to the coauthorship network of medical scientists. I show that network position is crucial for productivity by facilitating access to nonredundant knowledge. Identification results from vari...

摘要：This paper explores how firms that lack expertise in machine learning (ML) can leverage the so-called AI Flywheel effect. This effect designates a virtuous cycle by which as an ML product is adopted and new user data are fed back to the algorithm, the product improves, enabling further adoptions. However, managing this feedback loop is difficult, especially when the algorithm is contracted out. Indeed, the additional data that the AI Flywheel effect generates may change the provider's incentiv...
