摘要：We study the optimal management of evolving hierarchies of revenue-generating agents. The initiator invests into expanding the hierarchy by adding another agent, who will bring revenues to the joint venture and who will invest herself into expanding the hierarchy further, and so on. The higher the investments (which are private information), the higher the probability of expanding the hierarchy. An allocation scheme specifies how revenues are distributed, as the hierarchy evolves. We obtain sc...

摘要：Many retailers are reducing store footprint and downsizing their assortments accordingly to improve store productivity. Some of the revenue for items removed from the assortment may be recouped by substitution, but also some of the revenue for items kept in the assortment may be lost due to basket abandonment. For a practical setting where baskets may contain any subset of items from thousands of products, estimating both substitution and basket effects is a challenge. To address this, we deve...

摘要：We propose and analyze the first model for clinical trial design that integrates each of three important trends intending to improve the effectiveness of clinical trials that inform health-technology adoption decisions: adaptive design, which dynamically adjusts the sample size and allocation of interventions to different patients; multiarm trial design, which compares multiple interventions simultaneously; and value based design, which focuses on cost-benefit improvements of health interventi...

摘要：An increase in a country's sovereign risk, as measured by credit default swap spreads, is accompanied by a contemporaneous depreciation of its currency and an increase of its volatility. The relation between currency excess returns and sovereign risk is mainly driven by default expectations (rather than distress risk premia) and exposure to global sovereign risk shocks and also emerges in a predictive setting for currency risk premia. We show that a sovereign risk factor is priced in the cross...

摘要：Nonprofits regularly use conditional thank you gifts to entice prospective donors to give, yet experimental evidence suggests that their effects are mixed in practice. This paper uses multiple laboratory experiments to test when and why thank you gifts vary in effectiveness. First, we demonstrate that although gifts often increase donations to charities that donors did not rate highly, many of the same gifts had no effects or negative effects for charities that prospective donors already liked...

摘要：Classic inventory theories typically focus on the operational trade-offs to optimize inventory decisions. However, managers of public firms who obtain stock-based incentives may alter inventory operations to influence the stock price. We develop a stylized model, which shows that, in the presence of an interest in the stock price, managers over-install inventory when it can either inflate sales or deflate the reported cost of goods sold even if the market anticipates such actions. We analyze t...

摘要：We examine how the introduction of monetary incentives by a knowledge-sharing platform affects the nonrewarded knowledge activity on the platform. Our setting is a question-and-answer platform that provides monetary incentives for holding live talks. Using a combination of coarsened exact matching and difference-in-differences estimation techniques, we find that the launch of the paid feature creates a positive spillover effect on the hosts' free contributions, specifically, 9.4%-40.8% more an...

摘要：When confronted with a new product, consumers often find it difficult to predict how it will perform, and such uncertainty reduces consumers' willingness to adopt the product. In this paper, we consider a market whereby consumers decide when and which product to buy, given that they know the product quality of the incumbent but are uncertain about that of the entrant. We investigate how consumer uncertainty about product quality affects firms' behavior-based pricing and customer acquisition an...

摘要：Medicare does not pay for a skilled nursing facility (SNF) unless a fee-for-service patient has stayed in the hospital for at least three days. This Medicare reimbursement rule, or the three-day rule, provides full coverage for the first 20 days and partial coverage for days 21-100 for skilled nursing care provided at any Centers for Medicare and Medicaid Services-approved SNF. In this paper, we study how this Medicare reimbursement rule affects patient routing to SNFs and whether an SNF disch...

摘要：We examine the impact of providing access to mobile savings accounts and im-proving financial management skills on the performance of microenterprises in Mozambique. The effects are highly heterogeneous: Combining both types of support is associated with a large increase in both short-and long-term firm profits and in financial security for female microentrepreneurs. This allowed female-headed microenterprises, particularly those with a higher level of profits at baseline, to close the gender ...
