摘要：Search advertising is the ordered list of advertisements that appears when a user searches for something in an online search engine. By construction, these ads differ in prominence: ads higher up the list are more prominent than ads lower down the list. However, search ads also differ in prominence in another way: prominence of advertiser. This paper examines how these two types of prominence interact in determining the click-through rate (CTR) of these ads. Using individual-level click-stream...

摘要：This paper examines the impact of improvements in marketing skills relative to finance skills among small-scale entrepreneurs. It addresses three important questions: (1) What is the impact of marketing or finance skills on business profits? (2) How do improvements in marketing and finance skills respectively affect different business outcomes? (3) When are increases in marketing relative to finance skills more beneficial? Through a randomized control study of 852 firms in South Africa, the an...

摘要：Secure messaging, or e-visits, between patients and providers has sharply increased in recent years, and many hope they will help improve healthcare quality, while increasing provider capacity. Using a panel data set from a large healthcare system in the United States, we find that e-visits trigger about 6% more office visits, with mixed results on phone visits and patient health. These additional visits come at the sacrifice of new patients: physicians accept 15% fewer new patients each month...

摘要：We introduce feature valuations, a new class of valuations that compactly capture preferences of agents who value items based on the features they possess. Such preferences are relevant in many important practical settings, such as Internet advertising markets (where impressions have associated attributes), labor markets (where workers' skills/titles correspond to features), and long-term bond markets (where coupon payments can be associated with features). We focus on settings where features ...

摘要：We model a corporate board evaluating a chief executive officer (CEO) of uncertain management ability. Each director receives a noisy private signal about CEO ability, after which directors discuss this ability and vote to retain or replace the CEO. Directors care about true CEO ability, since it affects their equity holding values; however, a CEO may impose costs of dissent on a director who votes to fire but fails to oust her. We relate the equilibrium CEO firing decision to board size, boar...

摘要：We study a two-stage model in which the agent's ability is initially unknown to any party, but the principal can choose a prehire screening scheme to discover the agent's ability before offering a contract. Perfect screening enables the principal to fine-tune the contract to the agent's ability, but it also prevents her from enforcing a contract that is contingent on subjective interim performance measures. Given that interim performance measures are critical for motivating first-stage effort,...

摘要：Can distance-related information asymmetries in credit markets be overcome with contract design and credit scoring models? To answer this question, we explore differences in foreign and domestic banks' credit contract terms and pricing models. Using a sample of firms that borrow from both domestic and foreign banks in the same month, we show that foreign banks are more likely to demand collateral and grant shorter maturity loans than domestic banks. Foreign banks also base their pricing on int...

摘要：We study a multiserver queueing model of a revenue-maximizing firm providing a service to a market of heterogeneous price-and delay-sensitive customers with private individual preferences. The firm may offer a selection of service classes that are differentiated in prices and delays. Using a deterministic relaxation, which simplifies the problem by preserving the economic aspects of price-and-delay differentiation while ignoring queueing delays, we construct a solution to the fully stochastic ...

摘要：When a cardiac lead fails, physicians implant a new lead and may opt to extract the failed lead and/or any previously abandoned leads. Because the risk of extraction increases in lead age, physicians may extract leads to reduce the future risk of mandatory extraction, due to either infection or limited space in the vein. We develop discrete-time semi-Markov decision process models for various types of cardiac devices to determine patient-specific, lifetime-maximizing extraction policies as a f...
